SUBJECT:
COMPLETION OF LICENSING ACTION FOR GENERIC LETTER 97 EDWIN 1. HATCH NUCLEAR PLANT, UNIT 2 (TAC NO. M99997)
Dear Mr. McCoy:
)
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, l
1997. Tne 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 Emergency Core Cooling System suction strainers.
- 3. Specify whether the current design-basis NPSH analysis differs from the most recent
/
analysis reviewed and approved by the NRC for which a safety evaluation was issued.
o
- 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.
