Dynamic response of plant for full load rejection (loss of Offsite Power Testing) RG 1.68, App A 5.n.n IP 72517 IP 72582 100% of RTP with electrical system aligned for normal full- power operation and load rejection method should subject turbine to maximum credible overspeed condition Steady-state plant operations with greater than 10% generator output (IP 72517 & 72582). Trip of the plant with breakers in specified positions so that plant loads will be transferred directly to the DGs following loss of house power Recirculation system flow control mode specified Performance in accordance with design, including: Automatic transfer of plant loads as designed, automatic start of DGs, automatic load of DGs in the specified sequence Reactor pressure remains below the first safety valve setting. Pressurizer safety valves do not lift All safety systems such as RPS, HPCI, DGs, and RCIC function without manual assistance Normal reactor cooling systems should maintain adequate core temperatures, and prevent actuation of the Automatic Depressurization System; however selected relief valves may function to control pressure Turbine bypass system operates to maintain specified pressure value Steam system power-actuated pressure relief valves open and close at specified value Pressurizer spray valves open and close at specified values. Reactor coolant temperature/pressure relationship remains within prescribed values Pressurizer level is maintained within prescribed limits SG level remains within prescribed limits 15.2.6 Loss of Nonemergency AC Power to the Station Auxiliaries BIBLIOGRAPHIC DATA SHEET (See instructions on the reverse) NRC FORM 335 (9-2004) NRCMD 3.7 U.S. NUCLEAR REGULATORY COMMISSION 1.
