APPENDIX A NOTICE OF VIOLATION Duke Power Company Docket Nos. 50-269, 50-270 & 50-287 Oconee 1, 2, and 3 License Nos. DPR-48, DPR-47 & DPR-55 As a result of the inspection conducted on October 5-6, 1981, and in accordance with the Interim Enforcement Policy, 45 FR 66754 (October 7, 1980), the following violations were identified.
A.
10 CFR 20.201(b) requires the licensee to make or cause to be made such surveys as may be necessary for him to comply with the regulations in 10 CFR Part 20.
(Surveys means an evaluation of the radiation hazard incident to the release of radioactive materials under a specific set of conditions.
When appropriate, such evaluation includes measurements of concentrations of radioactive material present.)
The regulations in 10 CFR 20.106 limit the concentration of radioactivity which may be released to unrestricted areas.
Oconee Nuclear Station Technical Specifications, Table 6.6-1, Part II, Report of Radioactive Effluents -- Airborne Releases, requires the total quantity of Tritium (H3 ) released to the unrestricted area from the station to be reported to the Commission.
Contrary to the above, samples of the Unit vent gaseous effluent flowpath to the unrestricted area were not routinely taken to determine the concentra tion or amount of tritium released for the calendar year 1980 or the first nine months of calendar year 1981. Also, the report required by Technical Specification Table 6.6-1 did not include the unit vent contribution of tritium released from the station.
This is a Severity Level V Violation (Supplement IV).
B.
Technical Specification 6.4.1 states that the station shall be operated and maintained in accordance with approved procedures. Section 6.4.1.g requires Radiation Control Procedures.
Health Physics Procedure HP/O/B/1004/50, Calibration Procedure: Eberline Models PS-1, PS-2 Portable Scalers Equipped with HP-210 probe, paragraph 3.0 Limits and Precautions, sub-paragraph 3.1 states that calibration of these instruments is to be performed on a quarterly basis.
Also HP/O/B/1000/55, Instrument Monitoring and Survey Procedure, Section 4.0, Procedure, sub-section 4.2.1 states that the instru ment calibration due date must be checked prior to use and that instruments due for calibration must be removed from service immediately.
Contrary to the above, on October 6, 1981, a smear survey was analysed utilizing Eberline portable scaler model PS-1, instrument no.
104, with a calibration sticker affixed stating that calibration was due on October 2, 1981. The instrument was used without checking the calibration due date.

Docket Nos. 50-269, 50-270 & 50-287 Oconee 1, 2, and 3 License Nos. DPR-48, DPR-47 & DPR-55 This is a Severity Level VI Violation (Supplement IV).
C.
Oconee Nuclear Station Technical Specifications, Table 4.1-3, Minimum Sampling Frequency, Item 9, Unit Vent Sampling, Check b., requires the unit vent to be sampled for particulate radioactive nuclides.
The sensitivity limit for lab analysis for this sample is required to be less than 10-"
pCi/cc.
Contrary to the above, on October 7, 1981, a gasket was determined to have been missing from the sample apparatus for an indeterminate amount of time on the Unit 3 unit vent. Also, the filter paper intended to collect par ticulate matter was found to have been misaligned permitting bypass flow.
Although the charcoal filter downstream of the particulate filter may have had some collection efficiency for particulates, this factor was unquanti fied and no assurance that the required sensitivity limit was met could be obtained.
This is a Severity Level VI Violation (Supplement IV).
Pursuant to the provisions of 10 CFR 2.201, you are hereby required to submit to this office within thirty days of the date of this Notice, a written statement or
. explanation in reply, including:
(1) admission or denial of the alleged viola tions; (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. Consideration may be given to extending your response time for good cause shown.
Under the authority of Section 182 of the Atomic Energy Act of 1954, as amended, this response shall be submitted under oath or affirmation.
The responses directed by this Notice are not subject to the clearance procedures of the Office of Management and Budget as required by the Paperwork Reduction Act of 1980, PL 96-511.
