icipated reactor conditions. (See Table 1 of the letter from Westinghouse Electric Corporation to U.S. Nuclear Regulatory Commission, July 16, 1975, for the cases that must be analyzed to form such an envelope.) 2. A description of the codes used, how cross-sections for cycle were determined, and what Fxy values were used. 3. A commitment to perform load-follow tests wherein FQ is determined by taking in-core maps during the transient. (Note: Westinghouse has outlined for both the NRC staff and the Advisory Committee on Reactor Safeguards (ACRS) an augmented startup test program designed to confirm experimentally the predicted power shapes. This program is presented in the Westinghouse Electric Corporation publication on, “Augmented Startup and Cycle 1 Physics Program,” WCAP-8575, August 1975 describes this program. The tests will be carried out at several representative - both 15 × 15 and 17 × 17 - reactors. The staff has endorsed these tests as has the ACRS in its June 12, 1975, letter for the Diablo Canyon plant. In addition, for the near term, the staff plans to require that those licensees who propose to depart from the previously approved peaking factor and target bandwidth perform similar tests (the precise ones will be determined on a case-by-case basis) to broaden the confidence in analytical methods by extending the comparison of prediction with measurement to include more and more burnup histories.
