The following information was obtained from the Commonwealth of Pennsylvania Department of Environmental Protection via e-mail:
"On January 11, 2013 the licensee informed the Department's Southeastern Regional Office of the Medical Event. The event is reportable within 24 hours per 10CFR 35.3045(a)(1)(i). Both the patient and referring physician were notified.
"On December 4, 2012 the patient received an iodine-125 prostate seed implant. The patient returned for the 30 day post-treatment follow-up CT scan on January 9, 2013. Upon review of the CT results on January 10, 2013, it was discovered that the prostate received approximately 60% of the intended dose. The D90 was determined to be 56 Gy out of a prescribed dose of 110 Gy.
"The potential cause of the event was noted as possible organ shift or incorrect depth placement of needles.
"The licensee plans to compensate for the undertreated area with follow-up external beam therapy. They will provide the Department a written report in 15 days. The Southeastern Regional Office plans to follow up with a reactive inspection."
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient. |

"At 1641 on January 20, 2013, the Technical Support Center (TSC) became non-functional when the ventilation system was secured and disabled by a fire alarm. Investigation of the alarm condition determined the fire alarm was not valid and would not reset. At 1830, Technical Support Center ventilation was restored by disabling the deficient fire alarm by using guidance in alarm response procedure APP-FP-KBLDG. The Technical Support Center was restored to functional status at 1830 on January 20, 2013.
"This event is reportable per 10 CFR 50.72(b)(3)(xiii) as described in NUREG-1022, Rev. 2 since this condition affected an emergency response facility for greater than facility activation time (one hour).

"On Sunday, January 20, 2013, at 2050 hours, with the reactor at 100% core thermal power, the station entered a 24-hour action statement to initiate a controlled shutdown and be less than 104 psig reactor pressure due to suspected leakage across the first stage pilot of safety relief valve (SRV) RV-203-3B and subsequent declaration of the SRV inoperable due to criteria specified in Pilgrim plant procedure 2.2.23.
"As background, the pressure relief system includes four (4) SRVs and two (2) spring safety valves (SSVs). The SRVs discharge through their individual discharge piping, terminating below the minimum suppression pool (torus) water level. The four SRVs are installed on the main steam piping in containment between the reactor pressure vessel and the flow restrictors.
"While at full power, indication of a steam leak across the first stage pilot of RV-203-3B was determined in accordance with criteria specified in procedure 2.2.23. Specifically, the SRV is inoperable if the pilot stage thermocouple temperature is 35 degrees F below its baseline temperature (with a lower decrease at the 2nd stage thermocouple) and cannot be explained by a corresponding downpower. The safety relief valve was subsequently declared inoperable and the Limiting Condition for Operation (LCO) for Technical Specification (TS) 3.6.D was entered. Due to the valve being declared inoperable the station is required to be shutdown and reactor coolant pressure below 104 psig within 24 hours per TS 3.6.D.2.
"Currently a reactor shutdown is in progress to initiate safety relief valve repairs.
"This event has no impact on the health and/or safety of the public.
"The USNRC Senior Resident Inspector has been notified." |

"This is a non-emergency notification. At approximately 1300 [EST] on January 21, 2013 preplanned maintenance will be performed which will remove AH-17, one of three Technical Support Center (TSC) Supply Fans from service. The scope of the maintenance is to replace and align the fan's sheave with a contingency to replace its drive belt. This maintenance is expected to be performed and completed within approximately 7 hours. If an emergency condition should occur, the ventilation system will be restored, but potentially not within the time required for activation of the TSC. In addition, the ventilation system will be restored, but potentially not within the time required for activation of the TSC. In addition, the Harris Nuclear Plant (HNP) emergency plan has procedural guidance for use of an alternate location in the event the TSC is not habitable. The on-call TSC Site Emergency Coordinator and Emergency Response Manager have been notified."
The licensee notified the NRC Resident Inspector. |

"At 15:51 CST, Waterford 3 experienced an uncomplicated automatic reactor trip from 84.5% reactor power. The actuations of the Reactor Protection System (RPS) and the Emergency Feedwater Actuation System (EFAS) resulted from Steam Generator #1 Low Level, which is at a nominal 27.4% narrow range setpoint. Safety systems responded as expected.
"All three (3) Emergency Feedwater Pumps started and injected into Steam Generator #1. Auxiliary Feedwater pump has been started, feeding both Steam Generators (#1 and #2) at levels above the EFAS low level setpoint. All control rods inserted by the automatic RPS actuation. Electrical power is being supplied from normal off-site power and condenser vacuum is available for Steam Generator heat removal via the Steam Dump Bypass Control system. There are no safety systems out of service or inoperable, nor any safety system TS [Technical Specification] LCO [Limiting Condition for Operation] actions entered.
"The cause of the Steam Generator #1 Low Level condition, and associated Reactor Trip, is under investigation. This event occurred during the initial power escalation from refuel outage RF18, after attempting to place C Heater Drain Pump (HDP), the first of three, into service. After starting, C HDP tripped for a reason not yet verified. Subsequently, based on initial Control Room operator observations, the Steam Generator #1 Main Feedwater control valve position was observed to be at 10-20% open, but with an open position demand signal of 100%. Main Feedwater response to the reactor trip (Rector Trip Override) was as expected."
