ploy design features that existing NRC guidance associates with the opposite reactor design (e.g., an advanced PWR design that employs an in-containment refueling water storage tank that is similar to the suppression pool of a current BWR design or an advanced BWR design that employs a large dry containment that is similar to a current PWR design). Therefore, for advanced PWR and BWR designs, the guidance provided for both PWRs and BWRs that is appropriate and consistent with the plant’s design features should be considered. Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. Compliance with GDC 38 requires that systems be provided to remove heat from the reactor containment. The system safety function is to rapidly reduce containment pressure and temperature after any LOCA and to maintain these indicators at acceptably low levels. This SRP section describes staff positions related to the design of containment heat removal systems. Requirements related to spray systems, heat removal systems, 6.2.2-6 Revision 5 - March 2007 cooling water sources, and cooling water recirculation are discussed. Regulatory Guide 1.82, Revision 3, provides guidance concerning sources of water that can be used for long-term recirculation cooling following a LOCA. Meeting the requirements of GDC 38 regarding the characteristics and designs of containment heat removal systems provides assurance that containment pressure and temperature will be reduced to and maintained at acceptably low levels after any LOCA, thereby protecting the safety function of the containment as an engineered safety feature. 2. Compliance with GDC 39 requires that the designs of containment heat removal systems allow for appropriate periodic inspection of important components, such as the torus, sumps, spray nozzles, and piping, to ensure the integrity and capability of these
