boundary. (2) The performance goals for the shutdown functions should be: (a) The reactivity control function should be capable of achieving and maintain- ing cold shutdown reactivity conditions. (b) The reactor coolant makeup function should be capable of maintaining the reactor coolant level above the top of the core for BWRs and be within the level indication in the pressurizer for PWRs. (c) The reactor heat removal function should be capable of achieving and main- taining decay heat removal. (d) The process monitoring function should be capable of providing direct readings of the process variables necessary to perform and control the above functions. (e) The supporting functions should be capable of providing the process cooling, lubrication, etc., necessary to permit the operation of the equipment used for safe shutdown functions. xAs defined in the Standard Technical Specifications. 9.5.1-32 Rev. 2 - July 1981 (3) The shutdown capability for specific fire areas may be unique for each such area, or-it may be one unique combination of systems for all such areas. In either case, the alternative shutdown capability shall be independent of the specific fire area(s) and shall accommodate postfire conditions where offsite power is available and where offsite power is not available for 72 hours. Procedures shall be in effect to implement this capability. (4) If the capability to achieve and maintain cold shutdown will not be avail- able because of fire damage, the equipment and systems comprising the means to achieve and maintain the hot standby or hot shutdown condition shall be capable of maintaining such conditions until cold shutdown can be achieved. If such equipment and systems will not be capable of being powered by both onsite and offsite electric power systems because of fire damage, an independent onsite power system shall be provided. The number of operating shift personnel, exclusive of fire brigade members, required to operate such equipment and systems
