phenomena, and the conservatism of calculational models and input parameters, in assessing containment design margins. General Design Criteria 52 and 53 provide design requirements to assure that the design can accommodate a periodic integrated leakage rate testing at design pressures, and to assure that the design permits periodic inspections and appro- priate surveillance programs. The basic functional design requirements for a leak tight containment barrier for piping systems penetrating the primary reactor containment are given in General Design Criteria 54 thru 57. The General Design Criteria provide design requirements for the installation of containment isola- tion valves on piping lines that penetrate the containment barrier. There are a number of different containment types and designs, and several aspects of containment functional design that are within the scope of SAR Section 6.2.1. The various containment types and aspects to be reviewed under this SRP section have been separated and assigned to a set of other SRP sections as follows: 1. Pressurized water reactor (PWR) dry containments, including sub-atmospheric containments (SRP Section 6.2.1.1.A). 2. Ice condenser containments (SRP Section 6.2.1.1.B). 3. Mark I, II, and III boiling water reactor (BWR) pressure-suppression type containments (SRP Section 6.2.1.1.C). 4. Subcompartment analysis (SRP Section 6.2.1.2). 5. Mass and energy release analysis for postulated loss-of-coolant accidents (SRP Section 6.2.1.3). 6. Mass and energy release analysis for postulated secondary system pipe ruptures (SRP Section 6.2.1.4). 7. Minimum containment pressure analysis for emergency core cooling system (ECCS) performance capability studies (SRP Section 6.2.1.5). A separate SRP section has been prepared for each of these areas. Areas related to the evaluation of the containment functional capability are treated in other SRP sections; e.g., Containment Heat Removal (SRP Section 6.2.2), Containment Isolation System
