SUBJECT:
COMPLETION OF LICENSING ACTION FOR GENERIC LETTER 97-04 LASALLE COUNTY STATION, UNITS 1 AND 2 (TAC NOS. MA0002 AND MA0003)
Dear Mr. Kingsley:
The U.S. Nuclear Regulatory Commission issued Generic Letter (GL) 97-04, " Assurance of Sufficient Net Positive Suction Head for Emergency Core Cooling and Containment Heat Removal Pumps," to all holders of operating licenses or construction permits on October 7,1997.
- The NRC issued GL 97-04 to confirm the adequacy of the not positive suction head (NPSH) l available for emergency core cooling (including core spray and decay heat removal) and containment heat removal pumps under all design-bas:s accident scenarios.
In GL 97-04, the NRC staff specifically requested that licensees provide the information outlined below for each of their facilities.
- 1. Specify the general methodology used to calculate the head lo ss associated with the emergency core cooling system (ECCS) suction strainers.
- 3. Specify whether the current design-basis NPSH analysis differs from the most recent analysis l'
reviewed and approved by the NRC for which a safety evaluation was issued.
- 4. Specify whether containment overpressure (i.e., containment pressure above the vapor l
- pressure of the sump or suppression pool fluid) was credited in the calculation of available j
NPSH. Specify the amount of overpressure needed and the minimum overpressure availab!e.
- 5. When containment overpressure is credited in the calculation of available NPSH, confirm that an appropriate containment pressure analysis was done to establish the minimum l
containment pressure.
