A review of the supporting analysis shows that this penetration | | seal may not be qualified to withstand the hydraulic pressure which could | | result from a postulated internal flooding event occurring due to a service | | water system pipe failure filling the valve pit and its above compartment | | prior to operator intervention. A failure of this seal during a postulated | | internal flooding event may result in the loss of motor operated valve | | movement in both trains of the service water system that would be needed | | following a design basis accident (DBA). | | | | "This design basis calculation and the penetration seal capability are | | continuing to be evaluated. However, this seal could potentially have | | prevented the service water system from meeting single failure criterion | | during a postulated service water system pipe failure. Therefore, Technical | | Specification (TS) 3.7.4.1 was entered due to less than two trains of | | service water system being operable as a conservative decision based upon | | the limited information immediately available to show acceptable seal | | integrity at the postulated conditions. The TS Action requires restoration | | of two independent service water system trains within 72 hours. Actions are | | in progress to install a qualified seal which will prevent the unacceptable | | flooding conditions from being able to occur. | | | | "This condition is being reported pursuant to 10 CFR 50.72(b)(3)(ii) as an | | unanalyzed condition that significantly degraded plant safety since this | | seal has been installed for five months and may have invalidated the | | independence between the two service water system trains. The NRC resident | | has been notified of the degraded condition." | | | | * * * RETRACTION RECEIVED AT 1002 EST ON 3/07/2003 BY WITTER TO CROUCH * * * | | | | | | "Beaver Valley Power Station (BVPS) Unit No. 2 retracts the notification | | made on 01/20/2003 at 20:13 hrs [EST] regarding the event reported under 10 | | CFR 50.72(b)(3)(ii)(B) [ENS #39526]. The previous notification identified a | | potential issue with a seal penetration which may have invalidated the | | independence between two Service Water System trains. | | | | "Subsequent analysis of the event identified that the installed penetration | | seal between the two Service Water System valve pits would have been capable | | of performing its intended safety function. Therefore, the separation and | | independence between the two Service Water System trains, as required by | | Technical Specification 3.7.4.1, would have been satisfied. | | | | "Given that both trains of the Service Water System were able to perform | | their safety functions, this was not a condition that significantly degraded | | plant safety." | | | | The licensee has notified the NRC Resident Inspector. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |General Information or Other |Event Number: 39575 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | REP ORG: MA RADIATION CONTROL PROGRAM |NOTIFICATION DATE: 02/10/2003| |LICENSEE: PERKINELMER LIFE SCIENCES |NOTIFICATION TIME: 14:29[EST]| | CITY: BOSTON REGION: 1 |EVENT DATE: 07/18/2002| | COUNTY: STATE: MA |EVENT TIME: [EST]| |LICENSE#: 00-3200 AGREEMENT: Y |LAST UPDATE DATE: 03/07/2003| | DOCKET: |+----------------------------+ | |PERSON ORGANIZATION | | |GLENN MEYER R1 | | |DON COOL EO NMSS | +------------------------------------------------+ | | NRC NOTIFIED BY: CARPENITO | | | HQ OPS OFFICER: CHAUNCEY GOULD | | +------------------------------------------------+ | |EMERGENCY CLASS: NON EMERGENCY | | |10 CFR SECTION: | | |NAGR AGREEMENT STATE | | | | | | | | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | POTENTIALLY MISSING PHOSPHORUS-32 SHIPPING PACKAGES | | | | Single packages containing P-32 (~14 day half-life) were destined for four | | different out-of-state locations (in CA, KS, NY and TX).

Additionally, of the two isolation check valves in the line, | | testing was unable to determine which one was leaking. | | | | "Based on indications of leakage during the LLRT, maintenance activities | | were started on one of the valves (HPCI-15CV). Upon removal of the | | HPCI-15CV bonnet it was noticed that the valve was not properly seated. | | Engineering is continuing to evaluate this condition. To facilitate | | continuing troubleshooting HPCI-15CV was manually closed by pushing the disk | | into the valve seat. The bonnet was re-installed and the LLRT was repeated. | | The other check valve in this line (HPCI-44) was not touched or manipulated | | during the period of time between successive LLRT's. | | | | "The results of the repeat LLRT were well within acceptance criteria limits | | demonstrating that HPCI-44 was properly performing its containment isolation | | function. Since HPCI-44 was working properly, the conditions that required | | an 8 hour 50.72 notification no longer apply.
