ENCLOSURE 1
Florida Power and Light Company
Docket No. 50-389
St. Lucie Unit 2
License No. NPF-16
The following violation was identified during an inspection conducted on
July 9 - August 12, 1985. The Severity Level was assigned in accordance with the
NRC Enforcement Policy (10 CFR Part 2, Appendix C).
Technical Specificaticn (TS) 6.8.1 requires that written procedures be
established, implemented and maintained covering activities recommended in
Appendix A of USNRC Regulatory Guide (RG) 1.33, Revision 2, February 1978.
Section 6 of Appendix A of RG 1.33 states that a loss of electrical
power / degraded power source is an event / activity which should be covered by
a written procedure.
Contrary to the above, Operating Procedure (OP) 2-0960030, DC Ground
Isolation, was not adequately established and maintained to reflect the
operating characteristics of the Unit 2 main steam isolation valve (MSIV)
air supply solenoid valve logic control circuit. This resulted in a Unit 2
reactor trip on July 18, 1985, when operators following the OP removed
fuses for the B MSIV air supply solenoid valve which caused the A MSIV to close,
thereby, resulting in a reactor trip on asymmetric steam generator pressure.
This is a Severity Level IV violation (Supplement I), Unit 2 only.
Pursuant to 10 CFR 2.201, you are required to submit to this office within 30
days of the date of this Notice a written statement or explanation in reply
including:
(1) admission or denial of the alleged violations, (2) the reasons
for the violations if admitted, (3) the corrective steps which have been taken
and the results achieved, (4) corrective steps which will be taken to avoid
further violations, and (5) the date when full compliance will be achieved.
Security or safeguards information should be submitted as an enclosure to
facilitate withholding it from public disclosure as required by 10 CFR 2.790(d)
or 10 CFR 73.21.
