St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 This letter provides the initial Florida Power and Light Company (FPL) response to Generic Letter (GL) 97-04, Assurance ofSufhcient Net Positive Suction Head for Emergency Core Cooling and Containment Heat Removal Pumps, for St. Lucie Units 1 and 2. The GL requested an initial response within 30 days of the date of the GL stating whether or not the requested information would be submitted, and whether or not the requested information willbe submitted within the requested time period.
As a result of recent inspection activities, licensee notifications, and licensee event reports (LER),
the NRC has identified a safety-significant issue that has generic implications and warrants action by the NRC to ensure that the issue is adequately addressed and resolved.
The issue is that the net positive suction head (NPSH) available for the emergency core cooling system (ECCS)
(including core spray and decay. heat removal) and containment heat removal pumps may not be adequate under all design-basis accident scenarios.
Licensees were requested to review the current design-basis analyses used to determine the available NPSH for ECCS and containment heat removal pumps that meet either of the following criteria:
(1) pumps that take suction from the containment sump or suppression pool following a design-basis LOCA or secondary line break, or (2) pumps used in "piggyback" operation that are necessary for recirculation cooling of the reactor core and containment (that is, pumps that are supplied by pumps which take suction directly from the sump or suppression pool).
FPL will provide the requested information for St. Lucie Units 1 and 2, but not within the requested time period.
St. Lucie Unit 1 commenced a steam generator replacement outage on October 20, '1997.
The outage duration, which is currently scheduled for 75 days, willhave a significant impact on the available Engineering resources.
Accordingly, FPL willprovide the 0
