as affected by adverse operational (i.e., water hammer) and environmental occurrences including cold weather protection, by abnormal operational requirements, and by accident conditions DRAFT Rev. 5 - April 1996 9.2.1-2 such as a loss-of-coolant accident (LOCA) with the loss of offsite power. Since the SWS normally has requirements that relate to cooling functions during normal plant operation as well as for safety functions, the review will include an evaluation of the capability of the system to perform these multiple functions. 2. The PSBSPLB also reviews the design of the SWS with respect to: 5 a. The capability for detection, control, and isolation of system leakage including the capability for detection and control of radioactive leakage into and out of the system and prevention of accidental releases to the environment. b. Measures to preclude long-term corrosion and organic fouling that would tend to degrade system performance. c. Provisions for system and component operational testing, including the instrumentation and control features that determine and verify that the system is operating in a correct mode (i.e., valve position, pressure and temperature indication). d. The effects of the failure of nonseismic Category I equipment, structures or components ofon safety-related portions of the SWS are taken into account in the 6 design. 3. The PSBSPLB reviews the SWS capability to flood the reactor containment should this 7 be required in a post-accident recovery situation. Review Interfaces8 The PSBSPLB reviews the system to determine that a malfunction, a failure of a component, or 9 the loss of a cooling source will not reduce the safety-related functional performance capabilities of the system. Specifically, PSBSPLB performs the following reviews under the SRP sections 10 indicated: 1. Review for flood protection is performed under SRP Section 3.4.1. 2. Review of the protection against internally-generated missiles is performed under SRP Section 3.5.1.1.
