iteria acceptable to meet the relevant requirements of the NRC’s regulations identified above are as follows for the review described in this SRP section. The SRP is not a substitute for the NRC’s regulations, and compliance with it is not required. However, an applicant is required to identify differences between the design features, analytical techniques, and procedural measures proposed for its facility and the SRP acceptance criteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. 1. In meeting the requirements of GDC 16 and 50 regarding the design margin for BWR pressure-suppression plants at the operating license stage of review, the peak calculated values of pressure and temperature for the drywell and wetwell should not exceed the respective design values. Also, the peak deck differential pressure for Mark II plants should not exceed the design value. Acceptable methods for the calculation of BWR pressure-suppression containment environmental response to loss-of-coolant accidents are found in NUREG-0588. 6.2.1.1.C-5 Revision 7 - March 2007 For Mark III plants, the calculated results for drywell pressure and temperature, containment pressure and temperature, and differential pressure between the drywell and containment should be based on the General Electric Mark III analytical model that was used in the ABWR and Grand Gulf analyses. The use of this model at the construction permit stage is acceptable if an appropriate margin (see below) between the calculated and design differential pressures is used. The Mark III analytical model has been verified by the large-scale Mark III test results. If an analytical model other than the General Electric Mark III analytical model identified above is used, the model should be demonstrated to be physically appropriate and conservative to the extent that the General Electric model has been found acceptable. In addition, it
