July 26, 2002 Mr. Anthony Pietrangelo Nuclear Energy Institute 1776 I Street, N. W.
Suite 400 Washington, DC 20006-3708
Dear Mr. Pietrangelo:
The Nuclear Regulatory Commission (NRC) has completed its review of the Nuclear Energy Institute Technical Specification Change Travelers, TSTF-411, Surveillance Test Interval Extensions for Components of the Reactor Protection System and TSTF-418, RPS and ESFAS Test Times and Completion Times (WCAP-14333) proposed changes to NUREG-1431, Rev. 2, Standard Technical Specifications Westinghouse Plants. The staff recommends modification of the proposed generic changes to the Westinghouse (NUREG-1431) STS.
The staff recommendations are as follows: for TSTF-411, revise the allowed bypass time for reactor trip breaker testing and for maintenance on the undervoltage or shunt trip mechanisms, and the surveillance test frequencies for performing neutron flux channel operational tests; for TSTF-418 revise Reviewers Notes, and the allowed bypass times for testing other channels when one reactor coolant pump breaker position channel is inoperable. In addition, the staff recommends several Bases changes for both TSTFs. These changes to TSTF-411 and TSTF-418 will establish STS that are consistent with the analysis, as accepted by the staff in safety evaluations for WCAP-15376-P, Rev. 0 (Proprietary) and WCAP-15377-NP, Rev. 0 (Non-Proprietary), both entitled Risk-Informed Assessment of the RTS and ESFAS Surveillance Test Intervals and Reactor Trip Breaker Test and Completion Times and in WCAP-14333-P, (Proprietary), and WCAP-14334-NP, (Non-Proprietary), both entitled Probabilistic Risk Analysis of the RPS and ESFAS Test Times and Completion Times, respectfully.
In addition, TSTFs 411 and 418 propose different TS requirements for one RTB train inoperable (NUREG-1431, Condition O). For Condition O Required Actions, TSTF-418 adds a 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> surveillance test bypass time allowance as a third note whereas, TSTS-411 modifies note 1 and deletes note 2 but does not address any note 3 changes. Therefore, the staff requests the TSTF include the appropriate notations with the next revisions to TSTFs 411 and 418 to show how individual licensees can prepare TS amendment requests that adopt either or both TSTFs without deviating from the TS approved by the staff.
Mr. Anthony Pietrangelo July 26, 2002 My staff has been in contact with Mr. Steve Wideman, Westinghouse Owners Group regarding the review status of TSTF-411 and TSF-418. Copies of the specific recommendations have been provided and the integration issue for these TSTFs was discussed during a conference call held during the week of July 22, 2002. This completes review of TAC Nos. MB2156 and MB2879.
Please contact me at (301) 415-1161 or e-mail wdb@nrc.gov if you have any questions or need further information on these proposed changes.
Sincerely,
/RA/
