EN Revision Text: PART 21 - ISSUES IDENTIFIED WITH THE ENTERPRISE DIESEL ENGINE SUBCOVER The following information is excerpted from a facsimile report submitted: "Engine Systems Inc. (ESI) began a 10 CFR 21 evaluation on November 18, 2016 upon notification of an issue with a subcover assembly at Perry Nuclear Plant. Attempts to install the subcover on their Enterprise diesel engine revealed two issues that prevented successful installation. First, one of the bolt holes was not fully machined through the entire depth of the subcover. Though the bolt could be inserted into the top of its corresponding hole, it would not pass completely through. The second issue was an interference between the rocker arm shaft and its mating pedestal. It was found that incomplete machining of the pedestal prevented the shaft from sitting flat on the pedestal. "The evaluation was concluded on 12/21/16 and it was determined that this issue is a reportable defect as defined by 10 CFR 21." The affected facilities are: First Energy - Perry Georgia Power - Vogtle Also listed was the following affected facility: Korea - Yonggwang Component: Subcover Assembly, P/N 1A-7846 * * * UPDATE ON 12/4/20 AT 1435 EST FROM DAN ROBERTS TO THOMAS KENDZIA * * * The following is the summary of a facsimile: Engine Systems Inc.

EN Revision Text: PART 21 REPORT - AMETEK 85-RP2675-01 POWER SUPPLY MOUNTING HARDWARE The following is a synopsis of a Part 21 report received by email: "SUMMARY - AMETEK Solidstate Controls recently discovered a concern with the structural integrity of the 85-RP2675-01 Rack Mounted Power supply. While qualifying a replacement part for an obsolete breaker, the left panel of the power supply came loose after the hardware had sheared during the seismic simulation testing of the qualification. The loss of structural integrity of the power supply led to internal shorting and a premature stoppage of the simulation testing. "PROBLEM - During a seismic event, a structural failure of the power supply enclosure resulting in a loss of output could occur. At this point, it is suspected that the failure is related to a variation in the components that increased strain on the power supply enclosure, and it is indeterminate if there is a widespread deviation. It is also possible that the cause of the failure is attributed to inadequately sized hardware that supports the bottom panel of the power supply. In the current design, there are 3 #10-32 machine screws through each of the side panels that fasten to the bottom panel to support the transformer. "AMETEK is unable to identify the actual structural support of power supplies in the field. In the recent testing performed, no support was provided under the power supply during the testing. If there is support in the end application from the bottom of the power supply, there may not be a structural concern as the connection screws would not be exposed to the same forces. In this instance, the power supply had been exposed to a peak acceleration of approximately 4.8 giga second. It should also be noted that acceptable results have been obtained in previous seismic tests and changes have not been made to the structure of the power supply since its initial design in 1996. "ACTION RECOMMENDED - At this time, there are no actions to take as the evaluation is ongoing. The next step is to determine if the screws are likely to become overstrained with enough seismic force. To do this, AMETEK is repeating the test with two new power supplies. One power supply will not have any changes made to the structure while the second power supply will be enhanced to improve its seismic withstand capabilities. "The enhancement is an increase in the size of the hardware to 1/4 inch bolts that connects the side panels to the bottom panel through 5/16 inch through holes with a nut and washers. In combination, these changes will increase the force required to shear the hardware [and] reduce the force on the bolt itself by allowing some movement to dampen the forces during a seismic event. While AMETEK believes this solution will be suitable, it has not been validated with a follow up seismic simulation test. Additionally, AMETEK is unable to determine the criticality of the applications the power supplies are installed in and if the safety function is required to be maintained during a seismic event, which will determine the need to take corrective actions. "A report of the next seismic test results will follow upon completion as a final evaluation. The current expected date for completion is May, 2020. For questions or clarifications in the meantime, please contact Ethan Salsbury, Quality Director, at 1-614-410-6293." * * * UPDATE ON 12/09/2020 AT 0819 EST FROM ETHAN SALSBURY TO OSSY FONT * * * The following is an update of a Part 21 report received by email: "ACTION RECOMMENDED - AMETEK does not consider this to be a likely failure based on these test results. Additionally, AMETEK is unable to determine the criticality of the applications the power supplies are installed in and if the safety function is required to be maintained during a seismic event, which will determine the need to take corrective actions. The following enhancements can be applied to power supplies in operation: - Add a #10-32 nut to each of the six (6) mounting screws to avoid any lateral movement of the sheet metal parts that would lead to potential elongation or striping of the fastener. - Add support to the bottom of the transformer to prevent horizontal forces on the support screws "Although recent testing did not result in a similar failure, AMETEK is taking actions to enhance the design of the power supply. On new power supplies, the mounting hardware will use ¬" bolts that connect the side panels to the bottom panel through 5/16" through holes with a nut and washers. In combination, these changes will increase the force required to shear the hardware reduce the force on the bolt itself by allowing some movement to dampen the forces during a seismic event."

The physician mistakenly delivered the larger dose (approximately 30 mCi) to the liver lobe that was to get the smaller dose (approximately 13 mCi). The dose to the second lobe was adjusted with left over Y-90 from the dose draw to give the proper dose to the other lobe (approximately 30 mCi). So one lobe received much greater than the intended dose, while the other lobe received the proper dose. RHB will follow up on this investigation." California 5010 Number: 101620 * * * UPDATE FROM ROBERT GREGER TO DONALD NORWOOD AT 1816 EST ON 12/2/2020 * * * The following information was received via E-mail: "The authorized user prescribed 31.57 mCi (1.17GBq) Y-90 to the right lobe of the liver and 13.22 mCi (0.49GBq) to the left lobe of the liver. "The higher dosage, 31.57 mCi (1.17GBq) Y-90 was delivered to the left lobe of the liver. "The prescribed dosage of 13.22 mCi (0.49GBq) would result in a dose to the left lobe of 7,000 rad (70Gy), however the delivered dose was 17,500 rad (175 Gy).

EN Revision Text: AGREEMENT STATE REPORT - DAMAGED GAUGE The following information was received from the Commonwealth of Virginia via email: "On October 20, 2020, a representative of the Virginia Radioactive Materials Program (VRMP) received a report from a licensee via email that a portable nuclear moisture/density gauge was damaged in a vehicle accident at the intersection of Airport Road and Hwy 156 in Sandston, Virginia. The report indicated that a Troxler soil density gauge (Model 3430, Serial # 36803, containing 8 milliCuries of Cesium-137 and 40 milliCuries of Americium-241/Beryllium) was being transported in its case in the bed of a truck. During the accident, the case was damaged and the gauge housing was cracked, but there appeared to be no significant damage to the baseplate, rod, shielding or sources. The licensee's survey of the gauge yielded readings of 8-10 mR/hr at a 6 inch distance from the gauge. The gauge was returned to the Ashland office then transferred to an intact case and transported to North East Technical Services [(NETS)] for further evaluation. The VRMP is working with the licensee to obtain additional information and this report will be updated once the licensee's investigation is complete and the information is received." VA incident no.: VA20005 * * * RETRACTION ON 12/08/20 AT 0922 EST FROM ASFAW FENTA TO SOLOMON SAHLE * * * The following retraction was received from the Commonwealth of Virginia via email: "On November 4, 2020, VRMP performed a reactive inspection. The inspector noted that on October 20, 2020, the licensee sent the gauge to NETS for leak testing and evaluation. The record from NETS indicated that no removable contamination was detected. It also concluded that every component of the gauge is functioning as it should and the gauge was deemed serviceable for field use. The licensee, however, reported this initially as a damaged gauge because of the small crack observed on the plastic case of the gauge. Since the gauge still functioned properly with no damage to any shielding components, the incident does not meet the reporting requirements of 12VAC5-481-1110 B. 2.(10 CFR 30.50 b.2). Thus, VRMP requests the NRC Operation Center retract this event report. " Notified R1DO (Bower) and NMSS Event Notification via email.|

EN Revision Text: DAMAGED MOISTURE DENSITY GAUGE The following information was received from ALLWEST Testing & Engineering, Inc. via email: "On October 29, 2020, an ALLWEST employee [the authorized user] was testing the density of freshly placed asphalt on Painted Sky Street in the Spring Hollow Ranch subdivision in Nampa, Idaho using a CPN MC-1 portable nuclear densometer (SN 9216). At approximately 1115 Mountain Daylight time, the gauge was damaged by a Cat CCS9 combination roller under the direction of Nampa Paving. "[The authorized user] was in the process of running a density test in AC mode when the roller backed up and impacted the gauge. The roller moved off of the gauge after impact. After impact, the handle was oriented at a 45-degree angle from the base of the gauge and the case was detached from the base. [The authorized user] moved away from the damaged gauge and cordoned off the area to prevent anyone from approaching the damaged gauge. "[The authorized user] immediately contacted the Meridian office assistant RSO [radiation safety officer] who contacted the Corporate RS. [The assistant RSO] and another ALLWEST employee [the employee] responded to the accident and initiated ALLWEST's emergency protocol. [The assistant RSO] used a survey meter to obtain readings around the damaged gauge. The readings indicated the nuclear sources were not exposed and the shielding was intact. The handle was placed back in the case, and the handle, case and base were placed in the transport box. The transport box was then placed in an overpak barrel and transported back to the ALLWEST office. "Additional readings were taken using the survey meter around the gauge at the ALLWEST office. All readings were consistent with the sources being in a shielded condition. "[The assistant RSO] contacted lnstrotek and discussed the condition of the gauge and the readings obtained from the survey meter. lnstrotek representatives indicated it was acceptable to ship the damaged gauge to them for disposal in the transport box. As an additional precaution, [the assistant RSO] and [the employee] wrapped the damaged gauge in lead sheeting and placed the wrapped gauge in the transport box. The transport box with the damaged gauge was then shipped to lnstrotek for disposal. "ALLWEST sent the personal dosimetry badges for [the authorized user], [the assistant RSO], and [the employee] to Landaeur for immediate evaluation. The radiation dosimetry report from Landauer indicated minimal exposure to all three individuals." The gauge contained 10 mCi Cs-137 source and a 50 mCi Am-241 source.|

Attempts to free the tool while still attached to the wireline were unsuccessful and the wireline was pulled resulting in the rope socket leaving the cable head, two weight bars, gamma ray neutron tool, and a 3 Curie AmBe-241 sealed source lodged inside the tubing. The licensee's attempts to retrieve the source have so far been unsuccessful, partly due to windy weather conditions and 1500 pounds of gas pressure on the well. The licensee contacted the state of Kansas on 10/21/2020 to report a stuck radioactive source downhole. The licensee made the decision to wait until spring when the field had less pressure and the weather was better to clean out the tubing to enable the fishing tool to reach the stuck logging tool. Kansas agreed with the delay on source recovery for better weather and required that a sign matching the requirements of K.A.R. 28-35-362 [with the exception of (2)(C) and (2)(H)(i)] be placed at the wellhead no later than December 24, 2020. At this time this incident is not considered an abandoned source, however, The state of Kansas determined that it was appropriate to go ahead and report to the HOO out of an abundance of caution in the event that the source is unable to be retrieved in the spring of 2021."|

EN Revision Text: AGREEMENT STATE REPORT - STUCK OPEN SHUTTER The following information was obtained from the State of Iowa via email: "A maintenance technician at the 3M facility in Knoxville, Iowa discovered that a Thermo Fisher Scientific model SULP-77A fixed gauging device containing 661 milliCuries of Krypton-85 had a shutter that was stuck open and would not close. This discovery occurred when the production line was shutdown for routine maintenance. The RSO [Radiation Safety Officer] and backup RSO were notified and the gauge was isolated with caution tape to prevent personnel from getting close to the device. 3M maintenance personnel are authorized to perform shutter repair under the supervision of the RSO or backup RSO by Iowa radioactive materials license number 0042-1-63-FG. The licensee will provide a written follow-up report once repairs have been completed and the cause of the failure identified. "The licensee had a service provider operating under reciprocity with Iowa onsite November 17, 2020 to troubleshoot and repair the gauge. The root cause of the stuck shutter was a broken shutter return spring. A new shutter operating cylinder with a new return spring was installed and the gauge shutter was tested and found to be operating correctly. To minimize the chance of future shutter closure failures, the shutter operating cylinders will be replaced for all beta gauges of the same model that are currently in use at the site. Cylinder replacement will occur during future planned maintenance activities. These failures are exceedingly rare. This is the first occurrence in more than 20 years of using these gauges. The site is considering implementing a preventative maintenance replacement of these cylinders every 10 years." Iowa report number: IA200004|

The source rack, containing approximately 1.3 MCi of Co-60, was successfully returned to the shielded position and no exposures to personnel or the public resulted. All safety interlocks functioned as designed. This event did not result in any compromises to source security or to any safety or security systems. There is no indication of intentional misuse, theft or diversion at this time. "On 12/1/2020, the Agency was contacted by the Radiation Safety Officer for Sterigenics U.S., LLC, to advise that in the middle of performing scheduled routine safety checks on 11/30/2020, authorized engineers reported that the east source rack failed to return to the shielded position as designed upon completion of a check. The west source rack lowered as designed without incident. Sources contained in the east source rack remained unshielded from approximately 1400 CST until 1648 CST. The event was immediately reported to the Radiation Safety Officer by the two authorized engineers performing the safety checks that day. The Radiation Safety Officer immediately responded to the site to assist in assessment and formulation of an action plan. After consultation with the Corporate Radiation Safety Officer, the Radiation Safety Officer and staff engineers were able to use a hand winch to successfully lower the rack of sources into the shielded position within the pool. Safety and security systems remain operational and functioned as designed throughout the source lowering process. There is no immediate hazard to workers or members of the public as a result of this incident. "This morning [12/1/2020], source modules were removed without incident from the east source rack and are currently shielded and in safe storage at the bottom of the pool. Sterigenics staff are continuing their investigation into the cause for the stuck rack. All interlocks and safety systems were reported as operational. An action plan was formulated in conjunction with Corporate staff to safely and slowly raise the empty east rack using a hand winch so that it can be adequately inspected. IEMA staff will follow up later this afternoon for an update. "A reactive inspection by inspectors is planned for later this week." Illinois Reference Number: IL200024|

The source was extended and in use at the time. When the device was run over, the handle that is used to extend and retract the source rod broke off from the gauge completely, leading to concern that the source rod had also broken off. Personnel on site were evacuated and the area secured. "Because of the concern that the source rod had broken off, it was necessary to wait until a licensed entity that had the ability to handle the unshielded source arrived on site to continue recovery operations. Also, shortly after the incident, Northwest Technical Services (NTS), was hired for remedial action. "When NTS personnel arrived, they were able to determine that the source rod had not detached as feared. A leak test to check the integrity of the source revealed no leakage and the source rod was able to be retracted back into the shielded gauge. Radiation readings and additional leak tests in the area were conducted to ensure there were no remaining safety concerns. There were none.

"At 1908 EST on November 6, 2020, with Unit 3 in Mode 3, a partial invalid actuation of 'B' train Emergency Core Cooling System (ECCS) components occurred. The 'B' train SIH pump and the 'B' train RHS pump had started, and ran successfully on recirculation. Four Steam Generator Blowdown Containment isolation valves also closed. Due to this condition the 'B' Emergency Diesel Generator and the 'B' Emergency Generator Load Sequencer (EGLS) were declared inoperable and the required Technical Specification action statements were entered. Troubleshooting determined that this actuation was caused by a failure of one of the circuit boards in the 'B' train EGLS that caused a partial 'B' train 'SIS only' signal. Other 'B' Train components received the 'SIS only' signal but did not start because they were already running or were a backup to an already running component. Troubleshooting discovered a failed NAND gate on the 'B' Train EGLS XA93 circuit card. The card was replaced, retested, and the Technical Specification action statements were exited. "The pumps and valves responded in accordance with plant design. No other equipment was affected during this event. "There were no safety consequences or impacts on the health and safety of the public. The event was entered into the station's corrective action program. "The actuation was not due to actual plant conditions or parameters meeting design criteria for an ECCS actuation. Therefore, this is considered an invalid actuation.

The keys are stamped "AFT" on one end to identify orientation during installation. Keys supplied by ESI have ''AFT" stamped on the opposite end of where they should be stamped. If installed incorrectly and the condition goes undetected during post-maintenance inspection activities, engine performance could suffer resulting in inability of the emergency diesel generator set to perform its safety-related function. This issue is therefore considered to be a reportable defect as defined by 10CFR-part 21. The key is used in early Cooper-Bessemer model KSV diesel engines to locate the fuel pump cam on the engine's camshaft. This design has a stepped arrangement to provide 4-1/2 degree timing retard. The key is stamped "AFT" to designate the end facing the generator end of the engine. An additional "CAM" tamping designates the cam (up) surface. In the event the key is stamped incorrectly, it is feasible the key could be installed backward which would advance the timing by 9 degree from the desired position. Date which the information of the defect or failure was obtained is October 20, 2020. The extent of condition is limited to the part number supplied on the following two orders: Part Number (KSV-16-6E#1) Customer (Nebraska Public Power District (NPPD) - Cooper Nuclear Station) Purchase Orders: 1. NPPD Purchase Order Number (4500106009), ESI Sales Order Number (3006001), Quantity - 5 2. NPPD Purchase Order Number (4500106222), ESI Sales Order Number (3006017), Quantity - 5 Corrective Actions For affected users: Camshaft keys installed on engines: No action is required provided post-maintenance injection timing was verified and subsequent engine performance was successful. An incorrectly installed key would be evident by a shift in fuel injection timing. If injection timing and/or engine performance has not been verified, then additional inspections should be performed to verify installed keys from the above referenced orders are oriented properly. Camshaft keys in inventory (not-installed) on engines: Cooper Nuclear may elect to correct the mislabeled condition or return to ESI for rework. To correct the condition, surface grind to remove the existing "AFT" stamping. Stamp opposite end with "AFT" designation. For affected ESI: The dedication report will be revised to add clarification of the correct end for the "AFT" stamping. This will be completed by December 18, 2020.

EN Revision Text: AUTOMATIC REACTOR SCRAM DUE TO LOW STEAM GENERATOR WATER LEVEL "On December 10, 2020 at 1608 CST, Arkansas Nuclear One, Unit 2 (ANO-2) experienced an automatic reactor scram from 100 percent power due to Low Steam Generator Water Level in 2E-24A Steam Generator. Emergency Feedwater actuated automatically due to low water level in the A Steam Generator. Due to inadequate control of the B Main Feedwater Control System, water level in the B Steam generator rose to a level requiring manual trip of the B Main Feedwater pump. Emergency Feedwater responded as designed to feed both steam generators automatically. "All other systems responded as designed. All electrical power is being supplied from offsite power and maintaining unit electrical loads as designed. "Unit 2 is currently stable in Mode 3 (Hot Standby) maintaining pressure and temperature via Emergency Feedwater and secondary system steaming. "There are no indications of a radiological release on either unit as a result of this event. "This report satisfies the reporting criteria of both 10 CFR 50.72(b)(2)(iv)(6) for the Reactor Protection System actuation and 10 CFR 50.72(b)(3)(iv)(A) for the actuation of the Emergency Feedwater System. "The Arkansas Nuclear One NRC Senior Resident Inspector has been notified." * * * UPDATE FROM JOHN LINDSEY TO DONALD NORWOOD AT 1605 EST ON 12/11/2020 * * * "The purpose of this [report] is to provide an update to NRC Event Number 55028. "The cause of the inadequate control of the B Main Feedwater Control System to control B Steam Generator Level was verified to be associated with the failure that led to the A Steam Generator low level condition. "After taking action to trip the B Main Feedwater Pump, Emergency Feedwater was manually actuated for the B Steam Generator and the Emergency Feedwater System was verified to maintain proper automatic control of both Steam Generator levels. "At the time of the initial event notification, plant temperature and pressure control had been transferred from Emergency Feedwater to Auxiliary Feedwater along with secondary system steaming." The licensee notified the NRC Resident Inspector. Notified R4DO (Kellar).|

The station was conducting a surveillance test during a Unit 1 refueling outage to verify the proper responses of the EDG and the Engineered Safety Features Actuation Systems to simulated design basis events. During the test, technicians installed a jumper across incorrect relay points that caused the running Unit 1 'A' Train EDG to trip, resulting in a loss of power to the 'A' Train 4160 Volt Class Bus. "Following restoration of normal offsite power to the 'A' Train 4160 Volt Class Bus, the Loss of Power Actuation signal was reset, however, EDG start relay logic was not reset at the EDG Local Panel. This resulted in the Unit 1 'A' Train EDG and SP system actuations with the EDG running unloaded. The system actuations did not occur as a result of valid plant conditions or parameters and are therefore invalid. "The Unit 1 'A' Train EDG and SP system actuations were complete and the systems started and functioned successfully. "The event was attributed to a human performance error and entered into the corrective action program. There was no adverse impact to public health and safety nor to plant employees.

The AU felt the index rod loosen and then break off when he went to retrieve the gauge from its transport case. The gauge had been used the day before at a jobsite and did not experience any accidents. The gauge had not been dropped and was in the possession of the AU at all times during this event. The source remained in the shielded position within the gauge throughout this event. The AU contacted the radiation safety officer (RSO) and the gauge was transported to an authorized storage location. The RSO took measurements of the outer transport box surface (1 mR/hr) and the gauge surface (5 mR/hr). The gauge was placed into an authorized storage shed and readings at the surface of the shed were non-distinguishable from background. The gauge was a Troxler 3440 (s/n: 16938) with an 8 mCi Cs-137 source and a 40 mCi Am-241/Be source. NC event number: NC200023|

The shipper of the 475 mCi of iodine-131 Liquid (Yellow II label) delivered the package to the wrong address, a neighboring business. The package was delivered to the licensee by the recipient before the package was known to be 'lost', later on the scheduled delivery date. The surface reading of 12 mR/hr was obtained upon the licensee receiving the package. The package was estimated to be in the possession of the recipient for approximately 1 hour. The estimated dose was approximately 12 mrem if an individual had been in contact with the package for the entire time it was in the possession of the recipient. Since the material was delivered by the recipient within the time frame the shipper would normally deliver, and the facility had no reason to suspect the material was incorrectly delivered, the licensee will inform the shipper of the incident to handle training of their staff on proper delivery of radioactive packages." PA Event Report ID No.: PA200024 THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

Due to this inoperability, the system was in a condition that could have prevented the fulfillment of a safety function; therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v). All other emergency core cooling systems were operable during this time. "There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified." The high pressure core spray is inoperable because the water lake pump tripped. This inoperability puts the licensee in a 14-day limiting condition for operability.|

The gauge was locked in the transport case and placed in the vehicle, a pickup truck with a camper shell. During the short trip back to the office, the driver of another vehicle alerted the licensee's operator that the rear door of the camper shell was open. The licensee's operator then discovered that the gauge was missing, with one end of the chain used to secure the transport case loose. The licensee's operator backtracked to the jobsite in an attempt to find the gauge but did not locate it. The driver then notified the RSO and went to file a police report. Approximately 20-30 minutes after the RSO reported the incident to the Radiologic Health Branch, the RSO received a call from an individual who found the gauge. The gauge will be returned to the licensee. The gauge is a CPN International MC-3 (10 mCi Cs-137, 50 mCi Am-241:Be), S/N M39048766. The licensee's investigation into this event is ongoing and will be reviewed further by the California Department of Public Health."
