e assurance that, if the inspections, tests, and analyses are performed and the acceptance criteria met, the facility has been constructed and will operate in conformity with the combined license, the provisions of the Atomic Energy Act, and the NRC's regulations. SRP Acceptance Criteria Specific SRP acceptance criteria 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 GDC 16 requirements for functional capability of the secondary containment, the analysis of pressure and temperature response of the secondary containment to a LOCA in the primary containment should follow these guidelines: A. Heat transfer from the primary to the secondary containment should be considered. i. Heat transfer from the primary containment atmosphere to the primary containment structure should be calculated by conservative heat transfer coefficients like those in Branch Technical Position (BTP) 6-2. ii. Conductive heat transfer through the primary containment structure and convective heat transfer to the secondary containment atmosphere should be considered. iii. Radiant heat transfer to the secondary containment should be considered. B. Adiabatic boundary conditions should be assumed for the surface of the secondary containment structure exposed to the outside environment. C. The compressive effect of primary containment expansion on the secondary containment atmosphere should be considered. D. Secondary containment in-leakage should be considered.
