i ENCLOSURE 1
)
NOTICE OF VIOLATION Florida Power Corporation Docket No. 50-302 Crystal River Unit 3 License No. DRP-72 During an NRC inspection conducted on April 12 - 17, 1993, a violation of NRC requirements was identified.
In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C, the violation is listed below:
Technical Specification 6.8.1.a requires the establishment and implementation of written procedures for applicable procedures recommended in Appendix "A" of Regulatory Guide 1.33, November, 1972.
i Appendix "A" of Regulatory Guide 1.33, November 1972, section C includes instructions for changing modes of operation of the offsite electrical system (access circuits).
Contrary to the above, on April 8, electrical maintenance personnel removed a 500kV substation battery from service without an adequate procedure to delineate the evolution. The battery bus provides control power to the 500kV switchyard breakers in the offsite circuit which was in use as an offsite electrical source, powering safety related loads including decay heat removal systems. The evolution was improperly i
performed, resulting in tripping of the 500kV switchyard breakers. This deenergized the "B" 4160V Engineered Safeguards electric:1 bus in service which resulted in an automatic start of the "B" Emergency Diesel Generator and a three minute interruption in the operation of the decay heat removal system.
This is a Severity Level IV Violation (Supplement 1).
Pursuant to the provise ns of 10 CFR 2.201, Florida Power Corporation is hereby required to submit a written statement or explanation to the U.S.
Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555, with a copy to the Regional Administrator, Region II, and a copy to the NRC Resident Inspector, at the facility that is the subject of this Notice, j
within 30 days of the date of the letter transmitting this Notice of Violation (Notice). This reply should be clearly marked as a " Reply to a Notice of Violation" and should include for each violation:
(1) the reason for the t
violation or, if contested, the basis for disputing the violation, (2) the corrective steps that have been taken and the results achieved, (3) the corrective steps that will be taken to avoid further violations, and (4) the date when full compliance will be achieved.
If an adequate reply is not received within the time specified in this Notice, an order or demand for information may be issued as to why the license should not be modified, suspended, or revoked, or why such other action as may be proper should not be taken. Where good cause is shown, consideration will be given to extending the response time.
