teristics of a design-basis flood (DBF) and the SSCs that should be designed to withstand the effects of such an event and still remain functional. The CSF provides makeup water to systems that remove heat from the reactor if normal heat removal systems fail or are unavailable. In the event of a DBF, severe damage may occur to those systems that are not designed to withstand these effects. Compliance with GDC 2 provides assurance that the CSF will perform its safety function in the event of a DBF. 2. GDC 5 prohibits the sharing of SSCs among nuclear power plant units unless it can be shown that such sharing will not significantly impair their ability to perform their safety functions, including, in the event of an accident in one unit, an orderly shutdown and cooldown of the remaining units. The CSF provides a source of water for decay heat removal from the reactor core in those plants for which the design includes this system to support the plant in its response to an accident. Meeting the requirements of GDC 5 provides assurance that the unacceptable effects of equipment failures or other events occurring in one unit of a multiunit site will not propagate to the unaffected units. 3. GDC 44 requires that a system be provided to transfer heat from SSCs important to safety to an ultimate heat sink and specifies performance and design requirements that the system must meet. In those plants with a design that includes the CSF as a support function for heat transfer from SSCs important to safety, compliance with GDC 44 will ensure that the system will function to provide decay heat removal during normal operations, anticipated operational occurrences, and accident conditions. 4. Compliance with GDC 45 requires that the systems that provide essential cooling for safety-related equipment be designed to permit appropriate periodic inspection of important components such as heat exchangers and piping to ensure the integrity and capability of the system. The CSF can be
