UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON> D.C. 20555-0001 May 12, 1998 LICENSEE: Niagara Mohawk Power Corporation FACILITY:
Nine Mile Point Nuclear Station, Unit No. 1
SUBJECT:
SUMMARY
OF TELEPHONE CONVERSATION OF MAY11, 1998, REGARDING SCHEDULE FOR MODIFICATIONSTO CONTROL ROOM AIR'TREATMENT
'YSTEM (TAC NO. MA1653)
On May 11, 1998, Mr. Steven Leonard of Niagara Mohawk Power Corporation (NMPC or licensee) called me to discuss the schedule for completing modifications to the Control Room Air Treatment System for Nine Mile Point Nuclear Station, Unit No. 1 (NMP1). These modifications, identified in NMPC's application for license amendment dated May 2, 1998, would automatically initiate the Control Room AirTreatment System on either a main steam line break or loss-of-coolant accident signal. The modifications are being made to correct deficiencies that caused the licensee to declare the system inoperable and shut NMP1 down on April28, 1998, until the modifications are completed and the NRC issues the license amendment.
Because the licensee expected to complete the modifications in 1 week, and because power operation cannot resume until the amendment is issued, the licensee requested in the application that the NRC issue the amendment on an emergency basis in accordance with 10 CFR 50.91(a)(5).
During the call, Mr. Leonard explained that since the application for amendment was issued, a project team, consisting of engineers from Sergeant 8 Lundy and NMPC, has completed an independent design review to determine compliance of plant activities (operations, maintenance, testing and engineering) with the Control Room AirTreatment System's design and licensing basis.
The project team identified noncompliances with the system's design and licensing basis, mostly involving the lack of system redundancy and lack of documentation regarding the system's ability to maintain a habitable control room environment after an accident concurrent with a single failure in the system.
Mr. Leonard said that modifications to correct these deficiencies have been added to the scope of work to be completed before the system will be declared operable.
Consequently, the earlier estimate of 7 days has changed and NMPC now estimates that the modifications willbe completed in about 2 to 3 weeks.
