REQUESTS FOR ADDITIONAL INFORMATION (RAI)

ENERGY NORTHWEST COLUMBIA GENERATING STATION RELIEF REQUESTS RP-01, RP-02, RP-03 REQUEST FOR ALTERNATIVE RP-06 DOCKET NUMBER 50-387 By application dated April 2, 2014, to the U.S. Nuclear Regulatory Commission (NRC)

(Agencywide Document Access and Management System (ADAMS) Accession Number ML14101A365), Energy Northwest, the licensee, submitted a series of relief requests for the Columbia Generating Station Fourth Ten-Year Interval Inservice Testing Program.

Based on its review, the NRC staff requests the following additional information in order to complete their technical review.

EPNB-RAI-RP-01-1 Please provide the discharge pressures for standby service water pumps SW-P-1A and SW-P-1B, and standby service water, HPCS pump HPCS-P-2 from the inservice tests for the past year.

EPNB-RAI-RP-02-1 It appears that this alternative request is requesting the use of parts of Code Case OMN-16 for the standby service water pumps and the standby service water, HPCS pump. Please confirm if this is correct. If this is correct, please explain how your proposed testing differs from Code Case OMN-16 and provide justification for the differences.

EPNB-RAI-RP-03-1 Relief request RP-03 lists several elements that are used to develop and implement the provided reference pump curves. Relief request RP-03 states that these elements follow the guidance of Code Case OMN-16. Please clarify what portions of ASME OM Code Case OMN-16 are being followed. Also, please explain any deviations from ASME OM Code Case OMN-16 that are being requested in relief request RR-03.

EPNB-RAI-RP-06-1 Alternative request RP-06 provides a table that compares the test flow rate to the design basis accident flow rate. Please provide a table that compares test differential pressure and design basis differential pressure for the pumps for which an alternative is requested.
