Dear Mr. Linder:
SEPB
SUBJECT:
TMI ACTION PLAN ITEM II.K.3.21; RESTART OF CORE SPRAY AND LOW PRESSURE COOLANT INJECTION We have completed our review of your September 3,1980 submittal (LAC-7112) on the above item. The NRC position is that automatic start of the high pressure core spray is required in the event of a loss of water level at any time; but, restart of low pressure core sprays in the event of low water level after the initiation of the low pressure emergency core cooling system is not required.
The La Crosse Emergency Core Cooling System is designed to automatically start both High Pressure Core Spray (HPCS) pumps on a low reactor water level signal. As stated in the September 3,1930 submittal, the HPCS purps may be stopped by manually switching the pump control switches to the off position.
If a pump is switched to the off position, the switch is spring loaded to return to the automatic position when the handle is released. A reactor low water level signal will immediately restart the pump. Only by placing the switch handle in the pullout position can the operation of the HPCS pumps be inhibited. We conclude that the La Crosse design meets the requirements of NUREG-0737, Item II.K.3.21 for automatic restart.
Sincerely, Original signed by/
