| ENS 41525 | 25 March 2005 01:53:00 | The following information was obtained from the licensee via facsimile (licensee text in quotes): This is an 8-hour notification being made to report exceeding the design basis for the reactor coolant leakage outside of containment. The event is being reported under paragraph (b)(3)(v) of 10CFR50.72. An event or condition that could have prevented mitigating the consequences of an accident. On 03/24/05 at 2015 operators discovered that a closed manual discharge valve for the positive displacement charging pump was leaking through allowing Reactor Coolant System to leak back to the refueling water storage tank. The leakage was 0.34 gallons per minute. This leakage is greater than the UFSAR limit for ECCS leakage outside containment. With leakage greater than the UFSAR allowed limits (greater than 3800 cc/hr), GDC-19 limits for control room habitability cannot be assured. Actions were taken and the leakage was stopped at 2040. The affected positive displacement charging pump is not a safety related pump and is not required for accident mitigation; however it is in the ECCS recirculation flow path during the cold leg injection phase of the accident mitigation. The licensee will notify the NRC Resident Inspector of this event. The licensee will be notifying local authorities. The licensee reported that the event had no impact on Unit 1. |
| ENS 40823 | 17 June 2004 03:38:00 | At 0338 EDT on 06/17/04, the licensee reported that at 0321 EDT on 06/14/04, the licensee identified that the Salem Unit 1 #12 charging pump was declared inoperable due to an inoperable discharge check valve. Repairs to the check valve are not expected to be completed by 0321 EDT on 06/17/04. At 0022 EDT on 06/17/04, the licensee commenced a shutdown of Salem Unit 1 from 100% power to comply with Tech Spec 3.5.2, Emergency Core Cooling System Inoperable (72 hour LCO). #15 service water pump and #11 auxiliary building exhaust fan have been declared inoperable for scheduled maintenance. There were no personnel injuries or radiological occurrences associated with this event. This event has no effect on Salem Unit 2 which is at 100% power. The licensee notified the NRC Resident Inspector and plans to notify State and Local officials. |
| ENS 40806 | 11 June 2004 12:58:00 | On April 12, 2004, Salem station made an 8 hr report titled ACCIDENT MITIGATION - COMMON CONTROL ROOM EMERGENCY AIR CONDITIONING SYSTEM per 10 CFR 50.72(b)(3)(v) (Event number 40670). This report was the result of an invalid Unit 1 Safety Injection signal during troubleshooting/testing of Train 'B' of Solid State Protection. During the troubleshooting a card was moved from one slot to another, when the card was inserted into the new slot a safety injection signal was generated. The failed part of the card (a malfunctioning isolator card) was not used in its prior position, thus the failed circuit remained undetected. Further investigation determined that the safety injection signal was invalid; it was not the result of a plant condition requiring the protective action. Therefore this event is not reportable per 10CFR50.72(b)(3)(iv)(A) 'Any event or condition that results in valid actuation of any of the systems listed in paragraph (b)(3)(iv)(B) of this section, except when the actuation results from and is part of a pre-planned sequence during testing or reactor operation.' This event is reportable as it 60-day phone call in accordance with 10CFR50.73(a)(2)(iv)(A)(1) 'Any event or condition that resulted in manual or automatic actuation of any of the systems listed in paragraph (a)(2)(iv)(B) of this section, except when: (1) The actuation resulted from and was part of a pre-planned sequence during testing or reactor operation; or (2) The actuation was invalid..' Licensee event report 311/04-003 is being submitted to report the loss of accident mitigation capability for Unit 2. Event number for reference 40670. The licensee notified the NRC Resident Inspector. |
| ENS 40115 | 29 August 2003 15:22:00 | A 2-hour notification was made to the New Jersey Department of Environmental Protection due to a discharge of 100,000 gallons of industrial waste water to the Delaware River. The water contained a concentration of 300 ppb (parts per billion) hydrazine. The discharge was immediately terminated upon discovery. This is a common water treatment system for both Salem Units, however, there is no impact on plant operations. The licensee has notified the NRC Resident Inspector and the LAC (Lower Alloways Creek) Township. The New Jersey Bureau of Nuclear Engineering will also be notified by the licensee. |
