ENCLOSURE 1 NOTICE OF VIOLATION Florida Power Corporation Docket No. 50-302 Crystal River License No. DPR-72 During the Nuclear Regulatory Commission (NRC) inspection conducted on June 18-20, 1986, violations of NRC requirements were identified.
The violations involved control of potentially explosive gas concentrations in waste gas decay tanks and failure to take adequate corrective actions following previous notifications of similar problems.
In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1985), the violations are listed below:
A.
Technical Specification (TS) 3.7.13.5 requires the oxygen concentration in any waste gas decay tank (WGDT) to be less 'than 2% by volume whenever the concentration of hydrogen in the WGDT is greater than or equal to 4% by volume.
Action statement b for this TS requires whenever both the concentration of hydrogen and oxygen are each greater than or equal to 4% by volume in a WGDT, that waste gas additions to this tank be suspended and that without delay the oxygen concentration be reduced to within its limit.
Contrary to the above:
During the period of 11:37 p.m. on June 17, 1986, through 6:28 a.m. on June 18, 1986, the "B" WGDT had hydrogen and oxygen concentration that were greater than 4% by volume and waste gas additions to this tank were not suspended; and, During the period of 6:28 a.m. on June 18, 1986 through 7:00 a.m. on June 19, 1986, the "B" and "C" WGDT's exceeded the 4% hydrogen and oxygen limits and there was considerable delay before attempts were made to reduce the oxygen concentration to within it's limit.
This is a Severity Level IV Violation (Supplement I)
This is similar to a previous violation sent to you by our letter dated January 31, 1985.
B.
10 CFR Part Appendix B, Criterion 16 requires corrective action measures that assure that nonconformances are promptly identified and corrected and that such measures will prevent repetition of these nonconformances.
Section 1.7.1.16 of Florida Power Corporation's (FPC) Quality Program requires nonconformances to be promptly identified and corrected and that the corrective action taken be sufficient to prevent recurrence of the nonconformance.

Cr m al River License No. DPR-72 In a letter to the Nuclear Regulatory Commission (NRC) from FPC, dated June 6, 1985 in response to and providing corrective actions for the violation identified in NRC Inspection Report 50-302/84-33, the licensee i
stated that the waste gas disposal system procedure, OP-412, would be revised and that temporary nitrogen addition equipment would be utilized to provide a method to reduce the oxygen and hydrogen concentrations in the waste gas decay tanks (WGDTs).
Contrary to the above, FPC has failed to take prompt corrective action and, in a letter tc the NRC from FPC dated March 14, 1985, in response to a Deviation identified in NRC Inspection Report 50-302/85-44, FPC denied the Deviation to the above commitment based upon FPC's interpretation that the commitment did not include any specific pieces of the temporary nitrogen equipment, designate any specific location for the equipment, nor specify any actual use of the equipment.
As a result of this failure to take prompt corrective action on two separate occasions during the periods of January 5,1986 and June 17 to 19,1986, the temporary nitrogen addition equipment and even the nitrogen itself was unavailable to provide for a timely reduction of the oxygen and hydrogen concentrations in the WGDTs.
This a Severity Level IV Violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, Florida Power Corporation is hereby required to submit to this Office within 30 days of the date of the letter transmitting this Notic.e a written statement or explanation in reply includi.ng for each violation:
(1) admission or denial of the violation, (2) the reason for the violation if admitted, (3) the corrective steps which have been taken and the results achieved, (4) the corrective steps which will be taken to avoid fur'f.her violations, and (5) the date when full compliance will be achieved.
Where good cause is shown, cons'deration will be given to extending the response time.
