ATTACHMENT Re: Turkey Point Units 3 and 4 Docket No. 50-250, 50-251 IE Ins ection Re ort 250-85-05 and 251-85-05 fINDING 1:

10 CFR 50.55a(g) requires that inservice testing, to verify operational readiness, of pumps and valves whose function is required for safety, be accomplished in accordance with Section XI of the ASHE Boiler and Pressure Vessel (B and PV) Code. ASME B and PV Code,Section XI, 1980 edition through Winter 1980 addenda, has been identified as the applic-able code for inservice testing. ASME B and PV Code,Section XI, Para-graph IWV-3415, requires fail-safe valves he tested by observing the operation of the valves upon loss of. actuator power. The Hain Steam Isolation Valves have been identified as fail-safe valves.

Contrary to the above, inservice testing of pumps and valves and inservice inspection of components were not accomplished in accordance with ASME B and PV Code,Section X I, in that the Hain Steam Isolation Valves were fail-safe tested with the instrument air actively connected to the valve actuators.

RESPONSE

1) FPL concurs with the finding.
2) The reason for the finding was that an air reservoir cylinder existed in the air line to the main steam isolation valve (HSIV) actuator and it was assumed that air would always be available to the valve whether or not the instrument air supply was isolated.
3) a) An evaluation is underway to determine fail-safe testing requirements and acceptance criteria for the MSIVs in accordance with ASME B and PV Code, Section XI.'he results of this evalu-ation will be incorporated into the current inservice testing at Turkey Point, as applicable to the testing of the HSIVs . FPL notified the NRC of a 10 CFR Part 21 deficiency concerning the ability to close the main steam isolation valves (HSIVs) in Licensee Event Report (LER) 250-85-020. Our Engineering Depart-ment has determined that the design of the HSIVs will have to be modified to allow for fail-safe testing. The fail-safe testing criteria will be provided with the Plant Change Modification package for the MSIVs.=

b) This fail-safe testing criteria will be incorporated into existing plant procedures that implement Turkey Point's Inservice Testing Program. No change to the program is required.

IE Ins ection Re ort 250-85-05 8 251-85-05 c) In addition, an interim nitrogen supply system has been installed for Unit 3 and will be done for Unit 4 by the end of the current refueling outage to supply nitrogen to the t'SIVs.

The manually operated nitrogen supply supplements the existing i nstrument air system to ensure the t<SIVs can be maintained closed when necessary .

4) a) FPL has implemented a Program for Improved Operation that was described in our letters L-84-265 dated September 28, 1984 and L-84-275 dated October 3, 1984. As part of the scope of this program, operability and acceptance criteria are being developed to ensure that adequate testing and acceptance criteria is available to meet the operability requirements as described in the FSAR and Technical Specifications.
5) a) Full compliance for Item 3.a above will be achieved hy the end of the 1987 refueling outage for each Unit .

b) Full compliance for Item 3.b above will be achieved within 30 days after the end of the 1987 refueling outage for each Unit.

c) Full compliance for Item 3.c above will be achieved by the end of the current Unit 4 refueling outage.
