APPENDIX A NOTICE OF DEVIATION Duke Power Company License Nos. DPR-38 DPR-47, and DPR-55 Based on the results of the NRC inspection conducted on September 21-23,
- 1981, certain of your activities appear to deviate from your commitments to the Commission as indicated below: of Duke Power Company, Oconee Nuclear Station, commitment letter to the U.S.
Nuclear Regulatory Commission dated December 27, 1978, states that the quantity of radioactive material in the Chemical Treatment Ponds shall be limited so that, for all isotopes identified, excluding noble gases, the sum of the ratios of activity (in curies) to the limits in 10 CFR 20, Appendix B, Table II, Column 2, shall not exceed 1.7x105.
Contrary to the above, on Unit 2 a major tube leak in the "B" Steam Gener ator occurred on September 18,
- 1981, during which approximately 65,000 gallons of primary reactor coolant water leaked into the secondary system.
This incident resulted in cross contaminating the Condensate Polishing Demineralizer System.
During subsequent backwashes of the Condensate Demineralizer Filters, radioactive powdex resin was transferred to the Chemical Treatment Pond #2 (CTP). The sum of the ratios of activity to the limits in 10 CFR 20 for all isotopes identified through September 21, 1981, was 5.19 X 10'.
