Dear Mr. Stolz:
This letter is in response to a telephone conversation between Mr. L. D.
Young et al of Toledo Edison's Nuclear Licensing Department and yourself on August 26, 1982. The attachment contains the current status of TMI Items (NUREC 0737) of Generic Letter 82-05 after the current refueling outage for Davis-Besse Nuclear Power Station Unit 1.
Toledo Edison has just completed a refueling outage, which had several unforeseen problems. The turbine blade repair work and Auxiliary Feedwater Header replacement were the main work items which created a drain on the resources available for planned outage work load. During the outage there was a total manhour construction work force of 482,915 manhours on NRC required and equipment repair items, of that, 370,225 manhours were expended on NRC related work. These manhours do not include normal refueling related work, AFW header work nor turbine blade work.
Toledo Edison completed the following items of NUREG 0737:
ITEM TITLE II.B.1 Reactor Coolant System Hot Leg Vents II.E.1.2 Auxiliary Feedwater Initiation and Flow Indication II.F.1.3 In-Containment Radiation - Level Monitors II.F.1.4 Containment Pressure ce II.F.1.6 Hydrogen Concentration in Containment II.K.2.10 Anticipatory Reactor Trips System (ARTS)

September 17, 1982 Page 2 The following items of NUREG 0737 uere installed and are awaiting docu-mentation or they have all outage related work completed and a schedule for final completion is supplied.
ITEM TITLE REMARKS II.B.3 Post Accident Sampling All outage work is com-pleted and final work is scheduled to be completed by June 30, 1983.
II.F.2 Instrumentation for Deteat-During the 1982 refueling ing of Inadequate Core outage Toledo Edison Cooling enhanced its detecting cf inadequate core 1
cooling by adding core exit thermo-couples, new RTD's to the primary coolant Hot Legs and safety grade inouts to the T-sat meter. The system is operable, but the documentation of the environmental and seismic qualification of the Hot Leg RTD's is expected by the end of the year. Upon receipt of qualification docu-mentation of the RTD's Toledo Edison will meet the intent of Item II.F.2.
II.F.1.2 Iodine / Particulate Sampling All outage work is com-pleted and final work is scheduled to be completed by June 30, 1983.
II.F.1.5 Containment Vater Level During the 1982 refuel-ing outage Toledo Edison installed a containment vater level syatem to meet NUREG 0737 require-ments. The system s
Docket No. 50-346 License No. NPF-3 Serial No. 858 September 17, 1982 Page 3 ITEM TITLE REMARKS included a narrow and wide range level range.
The system is operable and meets the original license requirements for this type of instrumenta-tion, but the documenta-tion of the environmental and seismic qualifica-tion to meet NUREG 0737 requirements on the trans-mitters has not been received. The documenta-tion is expected by the end of the year.
The attachment reflects our current schedule on the listed NUREG 0737 items. We will keep you apprised of any major changes to the attached schedule.
