t removal from the reactor core in those plants where the design includes this system for support to the plant in its response to an accident. Meeting the requirements of GDC 5 provides assurance that unacceptable effects of equipment failures or other events occurring in one unit of a multi-unit site will not propagate to the unaffected unit(s). 3. GDC 44 requires that a system be provided to transfer heat from structures, systems, and components important to safety to an ultimate heat sink, and specifies performance and design requirements that the system must meet. In those plants whose design includes the CSF as a support function for heat transfer from structures, systems, and components important to safety, compliance with GDC 44 will ensure the system will function to provide decay heat removal during normal, anticipated operational occurrences, and accident conditions. 4. Compliance with GDC 45 requires that the systems which provide essential cooling for safety-related equipment be designed to permit appropriate periodic inspection of important components, such as heat exchangers and piping, to assure the integrity and capability of the system. The CSF can be included in the plant design to provide a source of cooling of the reactor core. In these plants, the CSF needs to be designed such that the ability to perform these safety-related functions can be periodically verified. By allowing for periodic monitoring to detect signs of system degradation or incipient failure, compliance with GDC 45 provides assurance that the CSF will reliably function to provide decay heat removal and/or cooling to safety-related equipment. 5. GDC 46 requires that systems that provide essential cooling for safety-related equipment be designed to permit appropriate periodic pressure and functional testing to assure the structural and leak-tight integrity of its components. The CSF can be included in the plant design to provide a source of cooling of the reactor core. This testing
