Dear ttr. Clayton:
Gray j
We have completed a preliminary review of your anendment request for Joseph ti. Farley linit No. 2 dated October 8,1982, supplenented by letter dated Decenber 10, 1982. You requested deletion of the Technical Specifications (3/4.3.4 Turbine Overspeed Protection) for periodic surveillance testing and inspections of turbine valves. The bases for this requirement is to ensure that turbine overspeed protection instrumentation and turbine speed control valves are operabl'e and will protect the turbine from excessive overspeed. This letter is in response to your request.
In your October 8,1982 proposal, your staff concluded that the potential to generate a turbine missile from a turbine overspeed condition is well below the NRC criteria, is ineffective and without cost benefits. You also concluded that " Technical Specification 3/4.3.4 can be deleted without an adverse inpact on the reliability of the turbine overspeed protection systen or without a reduction in overall plant safety."
Un have initiated action to obtain a detailed safety review of your contention that the weekly turbine valve testing is un. justified for Farley Unit No. 2.
He currently estinate the review would require about one year to complete.
Sone of our reasons for the lengthly schedule are as follows:
1.
This issue, the probability of turbine nissile generation, concerns j
turbine nanufacturers in addition to Westinghouse. Our staff is in the process of resolving the issue generically. Specifically, technical reports describing nethods and procedures for calculating design speed and destructive overspeed nissile generation probabili-l ties have been submitted to us by the Westinghouse Stean Turbine Division and are currently under review. These reviews are scheduled for coepletion within a year. The results will be directly applicable to Farley Unit No. 2 in that they will establish acceptable method:
for a,etting revised inspection and test schedules and procedures for essentially all Westinghouse turbine governor and overspeed protection systens.

2.
Your staff requests deletion of Technical Specification 3/4.3.4 arguing that accidental trips and refueling shutdowns satisfactorily demonstrate the operability of the turbine overspeed protection systen. However, this is not consistent with the current " Functional Test Requirenents for fluclear Turbines" supplied to customers by the liestinghouse Stean Turbine Division.
3.
Westinghouse Nuclear Energy Systens Report, WCAP-10161, used to support the request, requires extensive interaction with the manufacturer and cannot be completed on your requested schedule. Prior to conpleting our review we do not have an adequate basis to reach a decision on your your request. We propose to use HCAP-10161 in conjunction with our review of the Westinghouse qeneric reports on this issue.
In view of the above, we will not be in a position to decide on your request prior to completion of your generic review. Should you desire to appeal this decision, please advise the assigned NRC Project Manager.
Sincerely, Oricir.a1 signer w.
