- WASHINGTON, D.C. 20666 0001
\w/ j June 23, 1997 l APPLICANT: Westinghouse Electric Corporation PROJECT: AP600 i
SUBJECT:
I EUMMARY OF AP600 MEETING TO DISCUSS RESOLUTION OF OPEN ITEMS FOR REACTOR SYSTEMS PIRT/ SCALING CLOSURE REPORT L
The subject meeting was held on April 25, 1997, at the Rockville, Maryland, offices of Nuclear Regulatory Commission (NRC) between representatives of Westinghouse and the NRC staff. The purpose of the meeting was to provide the NRC staff an overview of how Westinghouse intends to closeout open items related to the reactor systems AP600 scaling and PIRT closure report (WCAP-14727).
Highlights from the meeting h cluded: l Westingbouse has prepared a matrix of all questions, comments, requests for additional information (RAIs), and commitments on the PIRT/ Scaling closure report from various sources.(NRC, ACRS, EPRI) to ensure that all outstanding issues are addressed in the revised report.
i' Westinghouse asserted that the final PIRT/ Scaling closure report will be a comprehensive, self-contained, stand-alone document. It will have an appendix that contains all applicable RAls and related issues. The report will also include an executive summary which provides an overview of the objectives, PIRTs, test facility scaling (both top-down and bottom-up) and a roadmap to appropriate sections of the report where detailed information can be found.
The report will include multi-loop systems (top-down) and a component (bottom-up) scaling analyses. The bottom-up scaling analyses will be compared with the PIRT and used to define success criteria to confirm tests with adequate scaling.
Westinghouse stated that the goal of the PIRT/ Scaling closure report is to show at least one test facility adequately scales to every high ranked phenomena in the PIRT.
Westinghouse noted that it was eliminating the NCTRUMP evaluation of pi-groups in Section 3 of the report and deleting Chapter 10 on the integration of test results into the codes. The NRC staff had no r M40 bjection to these changes.
Westinghouse and the staff reviewed the PIRT/ Scaling issues in the compliance matrix and noted the following actions:
The matrix will identify the specific ACRS meeting which each attributed ,

Matrix item 15 refers to a request from the staff to validate pi-groups l j using a mass balance approach. Westinghouse stated that mass balances j were previously used to analyze test results in the Quick Look and Final Data Reports. Instead, Westinghouse will' provide additional discussion in the report on pi-group validation using bottom-up scaling and will
] consider recent work done by INEL in this area.
1 Westinghouse agreed that the equation discussed in matrix item 29d was
! incorrect and will be fixed in the revised report.

Matrix item 36 should be combined with item 79. l For matrix item 49, Westinghouse needs to provide a reason why the use !
]- of governing equations, per Boure's paper, are not needed. l
! l Matrix items 55, 67, and 78 refer to oscillations observed during the i testing at 05U. The staff felt that the PIRT/ Scaling report should
] address the OSU oscillations to some extent. Westinghouse will
- re-examine this subject and determine if an appropriate discussion can l be included in the report.
j -
Matrix item 60 is missing the ACRS comment.
i Westinghouse needs to clarify why no action is necessary for matrix item i 62. I i i' 4
- Westinghouse also discussed schedules for the remaining PIRT/ Scaling actions.
- Westinghouse anticipated that the final report would be issued by the end of i May and was hoping to schedule an ACRS meeting in late June. In addition, j Westinghouse wanted to meet with the review staff once more after the report j was issued to finalize preparation for the ACRS.

Single Loop Analyses - Conclusions Conclusions from the Single Loop Systems Analyses are:
- Resistance / buoyancy, sensible heat / core power, boiling heat / core power, and convection heat / core power are the significant systems level X ratios.
- Inertia / buoyancy, phase change momentum flux / buoyancy (boiling and condensation) and single phase compliance / core power are insignificant and may be excluded from further consideration.
- SPES-2 sensible heat / core power during IRWST injection is distorted. This probably results from the small volume to surface ratio that accentuates the stored energy in the metal walls.
m.,,,. . .u.' 20
Single Loop Analyses - Conclusions Conclusions from the Single Loop Systems Analyses are:
- Both SPES-2 and OSU Two Phase Compliance / Core Power, One Phase Mechanical Compliance / Core Power, and Two-Phase Mechanical Compliance Core Power appear to be distorted. This may result from neglecting the steam volumes of non-active components.
- Scaling of both SPES-2 and OSU at the systems level demonstrates that these facilities are accurate simulations of the AP600 and between them, cover the important transfer processes within the distortion
- criterion.

- On basis of single loop scaling, expect bottom-up scaling to be successful
- Success criteria defined and numerical evaluations will be provided to confirm scaling
