SUMMARY
OF MEETING ON MARCH 18, 1997, REGARDING SOLUTION SET FOR EMERGENCY FEEDWATER AND EMERGENCY DIESEL GENERATOR LOADING PROBLEMS On March 18, 1997, representatives of the Florida Power Corporation, licensee for Crystal River Nuclear Plant, Unit 3 (CR3) met with members of the staff at NRC Headquarters in Rockville, Maryland to present their potential success path for emergency feedwater (EFW) flow and emergency diesel generator (EDG) loading concerns during a small break loss of coolant accident (SBLOCA) design basis scenario. is a list of attendees. contains copies of handouts distributed at the meeting.
The licensee discussed the composition of the team that is involved in resolving the design concern. The licensee stated that the limiting scenario affecting the EFW and EDG operation is the SBLOCA, loss of offsite power (LOOP) and three limiting single failures. The licensee indicated that its established success objective is to maintain one high pressure injection (HPI) pump and EFW flow. The licensee presented details about various modifications and analyses that would be necessary to meet its established objective.
The licensee also discussed its other long-term solutions including a diesel EFW pump or increased EDG capacity.
The staff questioned whether the licensee had considered the impact of other initiatives and corrective actions on the EFW/EDG resolution strategy. The licensee indicated that its team is generally aware of the other issues and does not expect them to affect the options discussed in the meeting.
The meeting was informational in nature and did not represent the licensee's final solution to the EFW/EDG concerns. The licensee did not request, and the staff did not make a determination on the acceptability of the information presented in the meeting. The licensee expects to finalize its position and raake appropriate submittals to the staff soon.
