This document defines the user,s process and functional requirements which shall be used as the basis for the preparation of the design for Project CGI-905, Interim Modifications for improved Coolant Backup 100-B, C, D, DR, F, and H Reactors. The objective in making these modifications is to provide improved reliability and adequacy in the last ditch reactor cooling systems for current and short-range forecast conditions. Performance requirements for the last ditch cooling system are based on the reactor cooling System criteria set forth in Document HW 66929. These performance criteria require that the last ditch cooling system be independent of both the primary and secondary cooling system, including piping to the reactor manifold, and that it must be capable of providing shutdown flow indefinitely, assuming instantaneous loss of power to the primary system and concurrent failure of the secondary system to provide its rated flow. The purpose of this document is to define the process requirements of the modifications and additions to the last ditch cooling systems and to outline the functional descriptions of the proposed equipment.
