OF DISCUSSION March 25, 2011 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of PSEG Nuclear, LLC (PSEG or the applicant) held a telephone conference call on March 25, 2011, to discuss whether a gas turbine, known as Salem 3, should be in the scope of license renewal. Hope Creek Generating Station (Hope Creek) has recently submitted a license amendment request (LAR H1 0-03) to the NRC concerning changing the Tech Specs for the A and B emergency diesel generators (EDGs) to allow a 14-day allowable outage time (AOT). Previously the AOT was 72 hours. On February 14, 2011, in letter LR-N 11-0045, PSEG proposed to include the gas turbine generator (aka Salem Unit 3) in the EDG Tech Specs as part of the defense in depth for the 14-day AOT. The gas turbine had not been scoped as part of license renewal for Hope Creek. In addition, it is not mentioned in the Hope Creek license renewal application or safety evaluation report. The question was whether, if the NRC approves LAR H1 0-03, the gas turbine generator should be in the scope of license renewal. The staff noted that the gas turbine did not appear to be in the scope of license renewal by 10 CFR 54.4(a)(1) as it was not safety-related. | OF DISCUSSION March 25, 2011 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of PSEG Nuclear, LLC (PSEG or the applicant) held a telephone conference call on March 25, 2011, to discuss whether a gas turbine, known as Salem 3, should be in the scope of license renewal. | ||

SUMMARY
OF DISCUSSION March 25, 2011 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of PSEG Nuclear, LLC (PSEG or the applicant) held a telephone conference call on March 25, 2011, to discuss whether a gas turbine, known as Salem 3, should be in the scope of license renewal.
Hope Creek Generating Station (Hope Creek) has recently submitted a license amendment request (LAR H1 0-03) to the NRC concerning changing the Tech Specs for the A and B emergency diesel generators (EDGs) to allow a 14-day allowable outage time (AOT).
Previously the AOT was 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. On February 14, 2011, in letter LR-N 11-0045, PSEG proposed to include the gas turbine generator (aka Salem Unit 3) in the EDG Tech Specs as part of the defense in depth for the 14-day AOT.
The gas turbine had not been scoped as part of license renewal for Hope Creek. In addition, it is not mentioned in the Hope Creek license renewal application or safety evaluation report. The question was whether, if the NRC approves LAR H1 0-03, the gas turbine generator should be in the scope of license renewal.
The staff noted that the gas turbine did not appear to be in the scope of license renewal by 10 CFR 54.4(a)(1) as it was not safety-related. It was also not in the scope of license renewal by 10 CFR 54.4(a)(3) as it was not required to perform a function that demonstrates compliance with the Commission's regulations for station blackout. The staff asked for a discussion of whether the gas turbine was a non-safety related component whose failure could prevent the satisfactory function of the EDG during the 14-day AOT and thus be in the scope of license renewal by 10 CFR 54.4(a)(2).
During the discussion, it was noted that the gas turbine was
- not required for the station blackout rule or any other regulation
- not a part of the plant design basis
- normally credited in the Hope Creek probabilistic risk assessment (PRA) but not risk-significant and not credited in the Hope Creek PRA for the extended EDG AOT During plant operations, any three of Hope Creek's four EDGs is capable of mitigating the consequences of a loss of offsite power (LOOP) concurrent with a loss-of-coolant accident or LOOP event while operating at full power. In an extended hot or cold shutdown condition, only two EDGs are required.
The gas turbine was required in the amendment as a defense in depth measure to provide an alternative means of accomplishing the safety functions provided by the EDGs during the 14-day AOT.

-2 The staff considered the information provided during the discussion and later informed the applicant that for extended EDG AOTs, the gas turbine, Salem 3, was not within the scope of license renewal because it is considered a temporary component as part of a compensatory measure and is non-safety related.
