PART 21 NOTIFICATION - NAMCO LIMIT SWITCH FAILED TEST DUE TO INSUFFICIENT LUBRICATION

The following information was received via email from Curtiss Wright:

"Curtiss-Wright was notified on August 7, 2018 by Exelon's Dresden Plant that a Curtiss-Wright Supplied Namco Limit Switch, P/N: EA700-90964 had failed during a planned maintenance test.

"The switch contacts were found to be sluggish in returning to the normal shelf state after actuation, or would not return at all. The switch was identified as Curtiss-Wright Tag Number 5T34603 and was provided as a safety related component to Exelon in September 2005. According to Exelon, the item was stored for 8 years, then failure occurred approximately 5 years into service. The part has a manufacturer date coded as August 2005.

"The switch was subsequently sent to Exelon Powerlabs where a detailed failure evaluation was performed. Exelon Powerlabs confirmed the failure mode and determined that there was insufficient lubrication in place to support normal switch function. The switch was then sent to Namco for further evaluation and Namco confirmed the lack of lubricant was the likely cause of the failure.

"Curtiss-Wright is currently investigating this issue and will provide a follow up report by November 15, 2018."


* * * UPDATE FROM TIM FRANCHUK TO DONALD NORWOOD AT 1335 EST ON 11/16/2018 * * *

The following information was received via E-mail:

"In reference to the Curtiss-Wright Interim Notification Report dated 10/8/2018 for an EA700-90964 limit switch failure, the following clarifications and updates are provided.

"The subject switch was originally supplied by Curtiss-Wright to Exelon's Dresden plant. Subsequently Dresden transferred the switch to Quad Cities where it was installed and found degraded and inoperable during a planned maintenance test. The initial notification of failure to Curtiss-Wright was by Quad Cities personnel, and not Dresden personnel. The switch was previously identified as Curtiss-Wright Tag Number 5T34603, which was incorrect. The actual Tag Number of the failed unit is 5T36403.

"The failure is still under investigation and Curtiss-Wright has been in communication with the manufacturer, Quad Cities personnel and Exelon Powerlabs personnel concerning the failure and application. A key factor in the failure appears to be heat related, specifically the switches operating temperature. As such, additional operating temperature data is being taken by Exelon personnel which will conclude in late February or early March 2019. Once this data is made available, a final conclusion as to the root cause of the failure can be determined.

"We therefore request additional time to complete our evaluation and should have our final report issued by March 8th, 2019."

AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE

The following was received via email from the State of Texas:

"On November 6, 2018, the licensee notified the Agency [Texas Department of State Health Services] that one of its Troxler model 3411 moisture/density gauges had been damaged at a temporary work site. The gauge contains an 8 milliCurie Cesium - 137 source and a 40 milliCurie Americium source. The initial report stated the casing and electronics were damaged but the shielding and insertion rod were not damaged.

"The licensee's Radiation Safety Officer (RSO) stated that at approximately 1430 [CST] on November 6, 2018, one of their technicians was working at a temporary job site. He had left the Troxler model 3411 moisture/density gauge on the ground about 10 feet behind him while he was preparing the test hole. A front end loader came into the area and struck the gauge with its back tire. The outer casing/shell of the device was broken as were the electronics. The source had been inside the gauge at the time. The insertion rod did not appear to be bent (didn't push it out to make sure), the shielding was not damaged, and survey did not detect any radiation above the same levels when sources are known to be fully shielded. The gauge was placed inside its transport case and transported to the licensee's facility for storage. The RSO stated the gauge would be taken to the service company for repair or disposal.

"On November 7, 2018, the Agency contacted the RSO and requested a picture of the device. The Agency received the pictures later that day. The Agency reviewed the pictures and the insertion rod for the cesium source appeared to have a slight bend in it. The Agency sent an e-mail request to the RSO and asked if the rod was operable.

"On November 8, 2018, the RSO responded to the Agency and stated they had not operated the source rod and he believed it would not be operable because of a slight curving bend in the operating rod. The gauge is still in storage at the licensee's location. The Agency will not ask the licensee to try and operate the rod as there is the risk that the source could get stuck in an unshielded position.

"Additional information will be provided as it is received in accordance with SA-300."

AGREEMENT STATE REPORT - RESIDUAL CONTAMINATION FOUND DURING SOURCE EXCHANGE

This report was received by the State of Illinois via e-mail:

"Varian Medical Systems reported that during a routine [high dose rate] HDR source exchange on 11/7/18, at Hinsdale Hospital, IL, they found residual contamination on a wipe sample of the wire from the source being removed from the device. The wipe activity measured less than leak test limits of 0.005 microCurie and measured 7.87 cps (40 Bq) with background measuring 0.45 cps. The source and wire were removed from the device. The wire was wiped prior to shipment to return the source to Alpha Omega. The area was immediately cordoned off by the engineer. Varian assumes this is a contaminated particle on the wire and that the source itself is not leaking. The wire is wiped prior to shipment from Alpha Omega and if contaminated it should not have been installed in the field. The source activity is now approximately 4.0 Ci of lr-192. The investigation is ongoing by the licensee and Varian."

STUCK OPEN SHUTTER ON PROCESS GAUGE

"In the process of performing the inventory/shutter check it was reported on November 09, 2018 at 1030 [EST] that our [Tilden Mining Co.] Kay Ray Model #7050, Serial #1412, 200mCi, Cs-137 gauge located on 6B DTU (Deslime Thickener U/Flow) in the deslime basement had a broken handle on the shutter mechanism, rendering the shutter non-operable. Work order (1836130) was entered into Ellipse. It was determined that the area in which the gauge is located does not create an exposure hazard.

"The plant process requires the shutter to remain in the open position during normal operation and does not create a hazard to individuals, the course of action will be to remove and replace the gauge at the first opportunity. Once the gauge is removed, it will be placed and locked in [a] cage. The gauge will be placed on top of the required amount of lead to remove any potential exposure hazard; surveys will be performed to confirm personal safety."

AGREEMENT STATE REPORT - IRRADIATOR SOURCE RACK FAILS TO RETRACT

The following was received via fax from the State of New York:

"The New York State Department of Health (NYSDOH) was notified by the radiation safety officer (RSO) of Pall Hauppauge (C1935) that they had a source rack which did not retract completely leaving the source partially exposed for a period of time. Pall Hauppauge is licensed to possess Cobalt 60 in sealed source use in a Nordian International dry panoramic storage irradiator.

"The RSO activated the radiation monitor remotely and confirmed elevated radiation readings. He indicated that he was able to raise the rack up and then lowered it down. This time it went completely down, resulting in the source being completely shielded.

"According to [the RSO], at no time were any workers exposed or potentially exposed, since there was no access to the vault. All other systems worked properly.

"[The RSO] indicated that they are conducting a root cause investigation. A written report will be forwarded to the Department."

AGREEMENT STATE REPORT - LOSS OF PET RADIOACTIVE MATERIALS DUE TO WILDFIRE

The following report was received from the State of California via email:

"On 11/09/18, RSO [Radiation Safety Officer] at Alliance Healthcare Services contacted the California OES [Office of Emergency Services] to report possible loss of control of radioactive materials that are located in one of their mobile PET [Positron Emission Tomography] Coaches stationed at the Feather River Hospital in Paradise, CA, due to a wildfire. A huge wildfire is still burning and spreading in the area and the extent of the damage is unknown, although the town of Paradise is reported to have been evacuated and heavily damaged in the fire. The PET Coach is believed to have contained Cs-137 (210 microCuries), Ba-133 (260 microCuries), and Ge-68 (3 milliCuries). RHB [California Radiation Health Branch] will be following up with the licensee once the area becomes accessible for inspection. This event report is being filed on the information that is known now about the extent of the fire and damage, and will be updated as appropriate when more complete information becomes available."

Notified the R4DO (Haire) and NMSS (via e-mail).

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.

EMERGENCY DIESEL GENERATOR ACTUATION DUE TO LOW VOLTAGE SIGNAL

"On 11/19/2018, at 1916 EST, with unit 2 in Mode 5 at 0 percent power, an actuation of the 'B' [Emergency Diesel Generator] EDG occurred during troubleshooting activities with the opposite train protected. The reason for the 'B' EDG auto-start was low voltage on the E-2 bus due to its supply breaker opening. The 'B' EDG automatically started as designed when the low voltage signal was received. Following the EDG start, required loads sequenced on as designed including the 'B' [Motor Driven Auxiliary Feedwater Pump] MDAFW Pump.

"This event is being reported in accordance with 10 CFR 50.72(b)(3)(iv)(A) as an event that results in a valid actuation of the Emergency AC Electrical Power System (Emergency Diesel Generator) and Auxiliary Feedwater System (Motor Driven Auxiliary Feedwater Pump).

"There was no impact on the health and safety of the public or plant personnel.

"The NRC Resident Inspector has been notified."
