SUBJECT:
BROWNS FERRY NUCLEAR PLANT, UNITS 2 AND3 COMPLETION OF LICENSING ACTION FOR GENERIC LETTER 97-04 (TAC NOS.'99964 AND M99965)
Dear Mr. Zeringue
, 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 objective of GL 97-04 was 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.
GL 97-04 requested the following information:
1.
Specify the general methodology used to calculate the head loss associated with the Emergency Core Cooling System (ECCS) suction strainers.
2.
Identify the required NPSH and the available;NPSH.
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.
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.
