safety related if its failure does not affect the ability of the reactor facility to achieve and maintain safe shutdown conditions. 1. The ASB evaluates the system design information and drawings and, utilizing engineering judgment, operational experience, and performance characteristics of similar, previously approved systems, to verify that: a. The system is capable of fulfilling the requirements of the facility for makeup water on a day-to-day basis. b. The component redundancy necessary for the system to perform its design function is provided. c. The potential for leakage and accidental spills has been minimized. d. Instrumentation (e.g., a conductivity monitor) has been provided together with the capability to isolate the system should planned operating conditions be exceeded. e. Piping has been provided as necessary to direct solutions and regenerative wastes to the radwaste system or other specified areas for processing and disposal. 2. The ASB also verifies, with input from the CMEB as requested, the following: a. Precautions are taken or incorporated into the system design to properly store, handle, and dispense corrosive and toxic chemicals effectively and safely so that safety-related systems would not be adversely affected in the event of a leak or spill. b. The components utilized are compatible with the associated chemicals. The review for seismic design is performed by SEB and the review for seismic and quality group classification is performed by MEB as indicated in subsection I of this SRP section. The ASB reviews the interface between seismic and nonseismic portions of the system and the isolation capabilities to assure that a failure of the nonseismic portion would not affect the seismic Category I portion and will not prevent safe plant shutdown. IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and the review supports conclusions of the following type, to be included-in the staff's safety evaluation
