The following information was sent by the State of Texas via email:
"On April 13, 2012, the Agency [Texas Department of Health] was notified by the licensee that a therapy event had occurred on April 11, 2012. A patient was prescribed 105 grays using Yttrium-90 microspheres. The patient received only 77.4 grays. The licensee stated that the reduced exposure was because a flow clamp was not in the fully opened position allowing microspheres to plate out in the flow tube instead of being administered to the patient. The licensee stated that there were no adverse effects on the patient.
"Additional information will be provided as it is received in accordance with SA-300."

This interim Part 21 is in regard to San Onofre Nuclear Generating Station, Unit 2, Steam Generator replacement.
"During the first refueling outage following steam generator replacement, eddy current testing identified ten total tubes with depths of 90 to 28 percent of the tube wall thickness. Some of the affected tubes were located adjacent to retainer bars. The retainer bars are part of the floating anti-vibration bar (AVB) structure that stabilizes the u-bend region of the tubes.
"Other tubes in the two steam generators had detectable wear associated with support points elsewhere in the AVB structure. Each steam generator has 9727 tubes with an 8 percent (778 tubes) design margin for tube plugging.
"Discovery Date: February 13, 2012
"Evaluation completion schedule date: May 31, 2012"

"On January 31, 2012, San Onofre Unit 3 shut down due to indications of a steam generator [SG] tube leak. Steam generator tube inspections confirmed one small leak on one tube in one of the two steam generators. Continuing inspections of 100% of the steam generator tubes in both Unit 3 steam generators discovered unexpected wear, including tube to tube as well as tube to tube support structural wear. Inspection, testing, and analysis of SG tube integrity in both Unit 3 SGs is ongoing. In-situ pressure testing identified eight Unit 3 SG tubes that did not meet the target performance criteria in Technical Specification for tube integrity. One of the failed tubes was the leaking tube that required the Unit 3 shutdown.

| This material event contains a "Category 3" level of radioactive material. | Event Text LOST STATIC ELIMINATOR
The licensee notified the Kentucky Department of Public Health and Safety, Radiation Health Branch on April 16, 2012 at 1135 (CDT) of a missing static eliminator. The static eliminator was discovered to be missing by an oncoming operator on April 13, 2012 at 0700 (CDT). An operator on the previous shift reported the device to be in place. The Director of Facility Operations was not in the office on April 13, 2012 and was not made aware of the missing device until April 16, 2012 at 0715 (CDT). The licensee initiated a search for the device on April 16, 2012 at 0715 (CDT) but has been unsuccessful in locating the device. The licensee plans to continue searching for the device. The licensee does not suspect tampering or theft and no exposures to personnel have occurred or are expected at this time. The device is a Model P-2021 Static Eliminator, Serial # A2HU670, with a 10 mCi Po-210 source.
Kentucky Radiation Health Branch Report number KY120007.
No other notifications have been made by the licensee.
THIS MATERIAL EVENT CONTAINS A "CATEGORY 3" LEVEL OF RADIOACTIVE MATERIAL
Category 3 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for some hours. It could possibly - although it is unlikely - be fatal to be close to this amount of unshielded radioactive material for a period of days to weeks. These sources are typically used in practices such as fixed industrial gauges involving high activity sources (for example: level gauges, dredger gauges, conveyor gauges and spinning pipe gauges) and well logging. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
Note: This device is assigned an IAEA Category 3 value based on the actual radioactivity of the source, not on the device type. (Reference IAEA RG-G-1.9) |

"Limerick Unit 1 was manually scrammed from 100% power at 0753 hours on 4/19/12 in accordance with plant procedure OT-112 'Recirculation Pump Trip' when both 1A and 1B Recirculation Pump Adjustable Speed Drives (ASDs) tripped due to an electrical fault affecting the 144D and 114A non-safety related 480V Load Centers. The shutdown was normal and the plant is stable in Hot Shutdown with normal pressure control via the Main Steam Bypass valves to the main condenser and normal level control using feedwater. The manual RPS actuation is reportable under 10 CFR 50.72(b)(2).
"The Technical Support Center (TSC) Normal Air conditioning systems shut down due to loss of power from the 144D Load Center. The loss of power also affects the flow indication for the Emergency Ventilation system. This is considered a Loss of Emergency Assessment Capability, and reportable under 10 CFR 50.72(b)(3)(xiii). The Emergency TSC Ventilation system is available but flow cannot be verified. During a required activation the TSC, responders would report to the TSC. If conditions required use of the Emergency Ventilation system, the Station Emergency Director would assess habitability in accordance with Station procedures. TSC relocation of personnel would be directed as required until such time that the TSC ventilation system is returned to service"

"On 04/19/12 at 1430 while performing 1-SR-3.5.1.7, HPCI [High Pressure Coolant Injection] Main & Booster Pump Set developed head & flow rate at rated reactor pressure. The HPCI turbine failed to trip using the manual trip pushbutton. This manual trip pushbutton should have caused the 1-FCV-73-18, HPCI TURBINE STOP VALVE, to go closed. HPCI was secured by taking the 1-FCV-73-16, HPCI TURBINE STEAM SUPPLY VALVE, to close. The 1-FCV-73-18, HPCI TURBINE STOP VALVE, also failed to go closed locally using the 1-XCV-73-18, HPCI TURBINE MECHANICAL TRIP, nor did it go closed when the auxiliary oil pump was secured.
"With the 1-FCV-73-18, HPCI TURBINE STOP VALVE, open, the HPCI ramp generator is no longer in the circuit therefore, should an initiation occur and cause the 1-FCV-73-16, HPCI TURBINE STEAM SUPPLY VALVE, to open there is the potential for the HPCI turbine to over speed. Therefore, HPCI was isolated using 1-FCV-73-3, HPCI STEAM LINE OUTBD ISOL VALVE. This incident is reportable as an 8-hour ENS notification under 10CFR 50,72 (b)(3)(v) as 'any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident.'
"It also requires a 60 day written report in accordance with 10CFR 50.73(a)(2)(vii).

"On March 22, 2012, McGuire Nuclear Station notified the NRC of a condition which could result in fire induced spurious operation of the block valves for the Unit 2 Steam Generator (SG) Power Operated Relief Valves (PORVs). This potential condition could adversely affect the ability to achieve and maintain a cold shutdown of Unit 2. This represented a condition reportable as per the requirements of 10 CFR 50.72(b)(3)(ii)(B). Reference Event #47764 [for Unit-2].
"In accordance with 10 CFR 50.72(c)(2)(i), McGuire is reporting results of ensuing cause and extent of condition evaluation of Event #47764, which has identified a similar condition on McGuire Unit 1. This condition could result in a fire induced spurious operation of the block valves for the Unit 1 SG PORVs. This spurious operation could potentially damage these valves and render them inoperable. Since these valves are unisolable, they could not be repaired to allow the Unit 1 SGs to be used for Unit cool down if needed. This potential condition could adversely affect the ability of the plant to achieve and maintain a cold shutdown of Unit 1. This represents a condition reportable as per the requirements of 10 CFR 50.72(b)(3)(ii)(B). This potential condition is mitigated by existing compensatory measures (i.e. fire watches) which have been in place as part of McGuire's transition to NFPA 805."

"At approximately 1724 EDT on April 19, 2012 with the Harris Nuclear Plant operating at 90% power in mode 1, Air Handler 17 was discovered not operating. Air Handler 17 provides ventilation supporting environmental habitability to the Technical Support Center (TSC) to keep ambient temperatures habitable for personnel and to ensure communications and assessment equipment remains functional. This degrades the heating and cooling capacity of the TSC by approximately one third. Due to the cool weather in the forecast, the remaining cooling systems will be operating more efficiently than they would in the hot summer months, which mitigates the impact of the degraded ventilation system. The system has been repaired as of 1950 EDT on April 19, 2012. The cause of the equipment failure was a broken belt and a condition report has been entered into the site's corrective action program. This report is being made in accordance with 10 CFR 50.72, criterion (b)(3)(xiii) as a condition that may impair the functionality of an Emergency Response Facility. The plant continues to operate at 90%. Other equipment functioned as expected. The on call Emergency Response Manager and Site Emergency Coordinator (TSC) have been notified and the alternate TSC is available."
