Dear Mr. O'Reilly:
Re:
St. Lucie Unit No. 2 Docket No. 50-389 Incorrect Valves Supplied and Installed On May 19, 1982 Florida Power and Light Company (FPL) notified the Region II Office of Inspection and Enforcement, in accordance with the require-ments of 10 CFR 50.55 (e), of a potential deficiency regarding the installation of AC solenoid rather than DC solenoid air control valves in the Sampling System. Attached please find our final resolution of this issue.
Very truly yours, d / 0 t Y

I.
Summary During review and inspection of the Sampling System it was determined that six pneumatically operated isolati'on valves had been installed with AC solenoid, rather than DC solenoid air control valves.
If these Sample System valves failed to close upon demand during an accident, a small amount of radioactivity could potentially be released from the containment.
Therefore, this issue is reportable according to the criteria of 10 CFR 50.55(e). The correct DC solenoid air control valves will be installed prior to core load.
II.
Description Pneumatically operated valves V-5200, V-5201, V-5202, V-5203, V-5204 and V-5205 supplied by Hoke have been installed with AC air control valves instead of DC air control valves.
However, Combustion Engineering Specifications 13172-PE-713 (R3) and 00000-PE-707 (RO) require 125 V DC soleno13s. This discrepancy was documented in Nonconformance Report 3649E and Discrepant Field Condition 1460.
III.
Corrective Action The air control valves will be replaced with 125V DC valves prior to core load.
IV.
Safety Implication If the above Sample System valves did not close upon demand during an accident, there could exist the potential for the release of small amounts of radioacti-j.
vity from the containment.
V.
_ Conclusion This issue is reportable according to the criteria of 10 CFR-50.55(e).
This report is final and completes requirements for reporting to the NRC.
