The assumed carryover fraction of 0.1% was discovered to | | be potentially closer to zero and therefore non-conservative in later model | | GE BWRs. | | | | "A review of Limerick Unit 2 moisture carryover data from an ASME PTC 6 test | | performed in October of 1999 found a moisture carryover value of 0.0277%, | | inducing an estimated bias of approximately 2.8 MWth.

CR-3 has identified a small defect in the | | reactor coolant system (RCS) pressure boundary. An RCS leak was suspected | | due to elevated radioactivity levels detected in the nuclear services closed | | cycle cooling water (SW) system since June 2001. Testing was conducted | | on-line in MODE 1 and could not determine the source of the leakage. | | Additional testing in MODE 6 has identified the seal area heat exchanger on | | the 1B reactor coolant pump (RCP-1B) as the most likely source of the | | leakage. The defect allowed a small amount of leakage to occur from the RCS | | to the SW system during the previous operating cycle. A definitive leak | | location could not be identified due to the extremely small size of the | | leak. However, since all components in the RCP heat exchanger are included | | as part of the class 1 RCS pressure boundary, this defect is reportable | | under 10 CFR 50.72(b)(3)(ii)(A). CR-3 was shutdown in MODE 6 at the time of | | the discovery. The RCP heat exchanger will be repaired prior to returning to | | power operation." | | | | The leak rate has been determined to be 0.02 gpm which exceeds the Technical | | Specification limit of 'No Pressure Boundary Leakage' and it appears to be a | | long term development. | | | | The licensee notified the NRC Resident Inspector. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 38349 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: RIVER BEND REGION: 4 |NOTIFICATION DATE: 10/04/2001| | UNIT: [1] [] [] STATE: LA |NOTIFICATION TIME: 16:10[EDT]| | RXTYPE: [1] GE-6 |EVENT DATE: 10/04/2001| +------------------------------------------------+EVENT TIME: 09:13[CDT]| | NRC NOTIFIED BY: DANNY WILLIAMSON |LAST UPDATE DATE: 10/04/2001| | HQ OPS OFFICER: FANGIE JONES +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: NON EMERGENCY |CLAUDE JOHNSON R4 | |10 CFR SECTION: | | |NONR OTHER UNSPEC REQMNT | | | | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 N N 0 Refueling |0 Refueling | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | OPERATING LICENSE CONDITION VIOLATION (POTENTIAL MAXIMUM POWER LEVEL | | VIOLATION) | | | | "This report is being made as required by River Bend Station license | | condition 2.E.

Both A and B Train Emergency Service Water Pumps (SWE) auto started | | as designed and Service Water header pressure returned to normal values. Due | | to a piping class break, safety/non-safety, between the SWS and SWE systems, | | the unit entered Technical Specification 3.0.3 due to two trains of Service | | Water being Inoperable. The unit entered and completed the Abnormal | | Operating Procedure for Loss of Service Water, and the Bravo Train of | | Service Water was restored Operable when 2SWE-P21 B was secured and isolated | | from the 'B' SWS header. 25W5-P21 B continued to operate normally during | | this event. Technical Specification 3.0.3 was exited at 0037 hrs. The plant | | is currently stable and operating at 100% power. Technical Specification | | 3.7.4.1 for Service Water (72-hour action) is applicable, as the only | | operating pump on the 'A' SWS header is 2SWE-P21A. The Alpha Service Water | | Pump, 2SWS-P21 A is unavailable due to Intake Structure Bay cleaning. | | Currently efforts are under way to recover the Intake Bay and restore | | 2SWS-P21A Operable. It is expected that both trains of Service Water will be | | Operable within 12 hours. The Non Safety Related Chiller units tripped due | | to the SWS low pressure conditions, and were recovered shortly there after. | | No additional failures or equipment challenges occurred as a result of this | | event." | | | | The licensee informed the NRC resident inspector. | +------------------------------------------------------------------------------+
