e OPEN ITEM ASSOCIATED WITH CHAPTER 20-650.13F' Treatment of WCAP-13559 in the SSAR Westinghouse's evaluation for the incorporation of- operating l experience-in the AP600 design is addressed in WCAP-13559 Revi-sion 1 " Operational Assessment for AP600." However, the WCt,P is

not clearly referenced from the standard safety analysis report-(SSAR). The incorporation of operating experience needs to be specifically addressed in the SSAR. The staff would find a section in the SSAR on operating ex>erience that references the WCAP an acceptable resolution for 111s issue. The treatment of WCAP-13559 in the SSAR is an open item.

650.14F Treatment of Bulletins and Generic letters that are the responsi-bility of the Combined License applicant On page 1 of WCAP-13559, Westinghouse describes the process that was used-to determine the applicability of Bulletins and Generic Letters to the AP600 design certification. One of the categories for the disposition of individual documents is "Not Applicable to the design certification due to other reasons..." The reasons given in this category include: procurement issue, administrative communication, procedural issue, plant specific / isolated event,.

and maintenance / surveillance-issue. Westinghouse needs to state in the SSAR that the Bulletins and Generic Letters that fall into this category will be addressed by the Combined License applicant.

The treatment of Bulletins and Generic Letters that are the responsibility of the Combined License applicant is an epan issue, m
