Subject:

NMP2 EPU - SBO scenario clarification

John, The technical staff requests additional clarification in NMPNS RAI response dated May 9, 2011, regarding the operation of the pumps during an SBO, particularly after the coping period. The RAI response stated that the SBO scenario was not included in the licensees evaluation as the RCIC pump is relied upon during the coping period. Nothing was said in the response about operation of other pumps past the SBO coping period. While the staff does not believe this to be a major concern in the completion of the associated draft SE section, its best to get a full understanding at this time as we prepare for our presentation/discussions with the ACRS.

Please let me know when you can support a conference call next week to discuss this area w/the tech staff. How about Wednesday 8/3?

Thanks, Rich Rich Guzman Sr. Project Manager NRR/DORL US NRC 301-415-1030 Richard.Guzman@nrc.gov
