River Bend Station Request for Additional Information (RAI) Regarding 24 Month Cycle Amendment (ME1872)
Barry and Dave, By letter dated August 9, 2009 (Agencywide Documents Access & Management System (ADAMS) Accession No. ML092470152), Entergy Operations, Inc. (Entergy, the licensee), submitted a license amendment request (LAR) to support 24-month fuel cycles at the River Bend Station. Specifically, the change addresses certain Technical Specification Surveillance Requirement frequencies that are specified as 18 months by revising them to 24 months.
The NRC staff has determined that the following additional information is needed to complete its review of the subject LAR for RBS. This request was discussed with Danny Williamson of your staff on August 6, 2010, and it was agreed that a response would be provided within 7 days of receipt of this email. If circumstances result in the need to revise the requested response date, please contact me at (301) 415-1445 or via e-mail at Alan.Wang@nrc.gov.
This amendment request addresses certain TS Surveillance Requirement (SR) frequencies that are specified as 18 months by revising them to 24 months in accordance with the guidance provided in NRC Generic Letter (GL) 91-04. The NRC staff has the following questions regarding the proposed SR changes:
- 1. With respect to Setpoint calculations, the licensee stated in page19 to Attachment 1 of the LAR dated August 10, 2009, As necessary, RBS setpoint calculations, and affected calibration and functional test procedures, have been revised, or will be revised prior to implementation, to reflect the new 30-month drift values. To ensure compliance with TSTF-493, Revision 4, or RIS 2006-17, provide the necessary calculations and affected calibration and functional test procedures for all instrumentations where the projected drift values are outside the existing design allowances.
- 2. With respect ot SR 3.3.8.1.3 and SR 3.3.8.1.4, the licensee is proposing to perform SR 3.3.8.1.3, Channel Calibration, at 18 months frequency and SR 3.3.8.1.4, Logic System Functional Test, at 24 month frequency. Provide justification for how and why the SR 3.3.8.1.3 can be performed at 18 months frequency and the SR 3.3.8.1.4 at 24 months frequency.
