SUBJECT:
CATAWBA NUCLEAR STATION - COMPLETION OF REVIEW FOR RESPONSE TO GENERIC LETTER 97-04 (TAC M99973 AND M99974)
Dear Mr. Peterson:
The U.S. Nuclear Regulatory Commission (NRC) 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 net positive suction head (NPSH) available for emergency core cooling (including core spray and decay heat removal) and containment heat removal pumps under all design-basis 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 loss associated with the ECCS suction strainers.
2.
Identify the required NPSH and the available NPSH.
O 3.
Specify whether the current design-basis NPSH analysis differs from the mest 4If recent analysis 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 pressure of the sump or suppression pool fluid) was credited in the calculation of available NPSH. Specify the amount of overpressure needed and the minimum overpressure available.
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 containment pressure.
In response to GL 97-04, you provided a letter dated January 5,1998, for Catawba Nuclear Station. This submittal provided the information requested by GL 97-04. The staff has
