Request for Additional Information: Columbia Generating Station - LAR to Revise Technical Specifications End States (TSTF-423, Revision 1) - TAC No. MF4616 Attachments: MF4616 - RAI.pdf Ms. Williams, By application dated August 12, 2014, (Agencywide Documents Access and Management System (ADAMS)

Accession No. ML14234A457), Energy Northwest (the licensee) submitted a license amendment request (LAR) to revise the Technical Specifications (TS) at Columbia Generating Station (CGS). The proposed amendment would modify the TS requirements for end states associated with the implementation of the approved TS Task Force (TSTF) change traveler TSTF-423, Revision 1, Technical Specifications End States, NEDC-32988-A, dated December 22, 2009 (ADAMS Accession No. ML093570241). TS Actions End States modifications would permit, for some systems, entry into a hot shutdown (Mode 3) end state rather than a cold shutdown (Mode 4) end state, which is the current TS requirement.

Based on the review of the license amendment request (LAR), the NRC staff has determined that additional information is required to complete its review. The formal request for additional information (RAI) is attached to this email. A clarification call was held on Friday, March 7, 2015, with members of your staff, and it was agreed that Energy Northwest would respond to this RAI within 30 days, which is April 8, 2015. If you have any questions, or have issues with meeting this date, please email or call.

Sincerely, Andrea George Project Manager Nuclear Regulatory Commission Division of Operating Reactor Licensing andrea.george@nrc.gov 301-415-1081 1

REQUEST FOR ADDITIONAL INFORMATION RELATED TO ADOPTION OF TSTF-423, REVISION 1, CHANGE IN TECHNICAL SPECIFICATIONS END STATES (NEDC-32988-A)

ENERGY NORTHWEST COLUMBIA GENERATING STATION By application dated August 12, 2014, (Agencywide Documents Access and Management System (ADAMS) Accession No. ML14234A457), Energy Northwest (the licensee) submitted a license amendment request (LAR) to revise the Technical Specifications (TS) at Columbia Generating Station (CGS). The proposed amendment would modify the TS requirements for end states associated with the implementation of the approved TS Task Force (TSTF) change traveler TSTF-423, Revision 1, Technical Specifications End States, NEDC-32988-A, dated December 22, 2009 (ADAMS Accession No. ML093570241). TS Actions End States modifications would permit, for some systems, entry into a hot shutdown (Mode 3) end state rather than a cold shutdown (Mode 4) end state, which is the current TS requirement.

In the course of its review, the NRC staff has determined that additional information is required to complete its evaluation, as discussed below.

RAI-STSB-1 Section 6.0 of the NRC staffs Safety Evaluation (SE) for Topical Report (TR) NEDC-32988, Technical Justification to Support Risk-Informed Modification to Selected Required Action End States for BWR Plants, Revision 2 (ADAMS Accession No. ML022700603), provides justification for the approved end-states related changes for the BWR/4 and BWR/6 standard TS.

In its LAR, the licensee proposes changes to the TS end states associated with several of its TS limiting conditions for operation (LCOs), as listed in the application. The licensee states in Section 2.2 of its LAR:

The proposed TS changes are consistent with TSTF-423, Revision 1. The TSTF traveler is based on NUREG-1433 Revision 3.0, Standard Technical Specifications General Electric Plants, BWR/4, and NUREG-1434 Revision 3.0, Standard Technical Specifications General Electric Plants, BWR/6. While Columbias TS are based primarily on NUREG-1434, a few Columbia TS are based on NUREG-1433.

Therefore, adaption of the TS markups contained in TSTF-423, Revision 1 is required.

The proposed variations/deviations are described in Table 1 of this document.

Since CGS is a BWR/5 facility, the NRC staff requests the licensee to review the NRC staffs SE for TR NEDC-32988, Revision 2 (ADAMS Accession No. ML022700603), to determine whether Columbias plant-specific systems, functions and nomenclature for the proposed changes in TSTF-423 are equivalent to those addressed in the Staffs SE. Please provide the results of that review, including a discussion of any differences. Table 1 of the LAR does not provide this level of detail.
