SUBJECT:
REQUEST FOR APPROVAL STATUS OF WCAP-9230 l
REFERENCE:
- 1. Telefax from Ray Ashley, AIB VINCOTTE NUCLEAIRE, to Robert Jones, USNRC, April 22, 1992
- 2. WCAP-9230, " Report On the Consequences of a Postulated I
Main Feedline Rupture." (Propreitary), January 1978 i
Dear Mr. Ashley,
In your Telefax (Ref. 1), dated April 22, 1992, a request was made for the approval status of reference 2 above (WCAP-9230). Your request stated that in 1985 a copy of the Westinghouse WCAP-9230 was received.
However, it was not approved at that time by NRC and no assessment of the report was available.
This report has not been formally reviewed and approved by the NRC for generic i
applications. However, this report has been used and accepted as a reference for over ten years for plant specific applications submitted to NRC. We note that the principal methods for analysis used in WCAP-9230 use three computer programs; NOTRUMP, for the detailed steam generator simulation, LOFTRAN, for
[
the complete transient analysis, and FACTRAN, to calculate the transient temperature distribution in the cross section of fuel rod and the heat flux at the surface of the rod. These three codes were not listed as approved at the time WCAP-9230 was issued but are now currently approved.
