lk REQUEST FOR ADDITIONAL INFORMATION ON THE SAFETY ANALYSIS TO SUPPORT

{

, THE TS CHANGES PROPOSED BY WPSC FOR KNPP (TAC NOS: MA1557)

- 1.

As a result of the findings of the Maine Yankee Lessons Learned Task Force, the staff has taken a position that licensees must verify conformance to any l

, conditions and limitations identified in the safety evaluation reports (SERs) that L

approved the analytical methodologies used in safety analyses supporting l

licensing applications. Accordingly, you are requested to confirm comformance to the conditions and limitations, if any, specified in the SERs for the methodologies used for the LOCA and non-LOCA transients analysis supporting y

the TS change 8.

2.

The non-LOCA analysis was performed for a full core design of SPC heavy fuel (Attachment 5, Page 2.) However, it appears (Attachment 4, Page 2) that the proposed Cycle 23 core is a mixed core with both SPC heavy fuel and SPC standard fuel. Please clarify the types of fuel used in the core. If a mixed core is proposed as a transition core for operation, discuss the mixed core penalty on t

the DNBR calculations and the methods used for assessment. Present the results showing that the ssfety DNB limits are not violated for the applicable i

trans!ents.

3.'

The discussions of the LOCA analyses does not identify the specific breaks that were analyzed and the limiting breaks for both small break and large break l"

LOCA cases.. Provide this information and explain you rationale for concluding L

that the limiting cases were identified and analyzed.

4.

The application does not include information for the steam generator tube l

rupture (SGTR) event. Explain why tne SGTR event was not considered in the l

application.

5.

For the locked rotor event, the application states that the percentage of fuel rods experiencing DNB depends on the reload calculation, however, no number was provided (Attachment 5, Page 5.) Please provide information to show that the acceptance criteria in SRP 15.3.3 for the locked rotor event are met.

Specifically, acceptance criterion ll.2 requires that "Any fuel damage calculated t

to occur must be of sufficiently limited extent that the core will remain in place and intact with no loss of core cooling capability," and acceptance criterion l1.3 W

requires that ".Any activity release must be such that the calculated doses at the

. site bcundary are a small fraction of the 10 CFR Part 100 guidelines."
