Dear Dr.Grace:

ATTACHMENT Re: St.Lucie Units 1 and 2 Docket iVos.50-335, 50-389 lns ection Re ort 335/85-17<<nd 389/85-17 FINDING 10 CFR 50, Appendix B, Criterion V, as impleinented by section 5.0 of FPRL Topical Quality Assurance Report, requires, in part, that activities affecting quality be prescribed by documented instructions, procedures and drawings and shall be accomplished in accordance with these instructions, procedures and drawings.Contrary to the above, plant modifications were performed on Unit 2 in 1980 per plant change/'modification (PC/M)-015-283 which added redundant over-current devices to electrical distribution systems to comply with iVRC Regulatory Guides 1.63 an'd 1.75.The addition of these devices resulted in some safety-related relays no longer being testable with the unit at power.On 3une 26, 1985, an attempt was made to perform Operating Procedure (OP)2-0000053, Engineered Safeguards Relay Test, for Semi-annual Surveillance.

The PC/M's did not modify~the procedures to prevent testing of certain relays.This resulted in a plant transient that almost tripped tne reactor.RESPONSE 1.FPL concurs with the finding.2.The reason for the violation was due to an oversight in the review of the applicable PC/i%i.It was not recognized that a change to procedure OP2-0000053 (Engineered Safeguards Relay Test, for semi-annual surveillance) would be required.3.The required change has been made to OP2-0000053.

Additionally, our Engineering Staff has been requested to review the design of the PC/M.0.The imgortafice of a thorough review of PC/M has been stressed to the appropriate personnel.

The procedure update method is being expanded to ensure applicable department reviews are complete.This is expected to be completed by October 1, 1985, which is in time for the PSL Unit 1 Refueling Outage.5.Full compliance will be achieved on October 1, 1985.
