DEC 0 6 1979 APPENDIX A NOTICE OF VIOLATION Duke Power Company License No. DPR-55 Oconee, Unit 3 Based on the NRC inspection November 15 and 16, 1979, certain of your activities were apparently not conducted in full compliance with NRC requirements as indi cated below. These items have been categorized as described in correspondence to you dated December 31, 1974.
A.
As required by Technical Specification 3.9.3, the rate,of release of radio active materials in liquid waste from the station shall be controlled such that the instantaneous concentrations of radioactivity in liquid waste upon release from the Restricted Area, does not exceed the values listed in 10 CFR 20, Appendix B, Table II, Column 2.
10 CFR 20.3(14) defines a Restricted Area as any area access to which is controlled for purposes of protection of individuals from exposure to radiation and radioactive materials.
Contrary to the above, on November 10 and 11, 1979, 176 gallons of water with a concentration of radioactivity totaling 3.45 times the values listed in 10 CFR 20, Appendix B, Table II, Column 2, were released to the site sewage treatment sump. There are no controls over the access of individuals in this area.
This is an Infraction.
B.
As required by Technical Specification 6.4.1.h, the radioactive waste management system shall be operated in accordance with approved procedures.
Station Directive 3.8.21, "Radioactive Waste Disposal" (6/8/79), Section 4.1.1 states all radioactive liquids must be disposed of only in sinks and drains that go to the liquid waste disposal system.
Contrary to the above, on November 10 and 11, 1979, 176 gallons of radio activity contaminated water from the A and B steam generators was drained to the sewage treatment system.
This is an Infraction.
C.
A's required by 10 CFR 50, Appendix B III, a Quality Assurance Program must include procedures to assure changes in facility design are reviewed by a designated organization. Station Directive 4.4.2, "Processing Nuclear Station Modifications" (4/25/79), implementing this requirement, requires all modifications of station systems be reviewed and implemented in accordance with procedures referenced in Section 6 of the Station Directive.

Duke Power Company Appendix A License No. DPR-55 Notice of Violation The Final.Safety Analysis Report (FSAR), Figure 9-3 shows steam generator sample lines being drained to the liquid waste system. FSAR Section 11.1.2.2 states low radioactivity liquids are routed to the low activity waste tank.
FSAR section 1A.70, design criteria for control of releases of radioactivity to the environment, states liquid wastes will be monitored for activity level at all times during release.
Contrary to the above, on November 10 and 11, 1979, radioactively contaminated liquids from the steam generators were discharged to the sewage treatment system using a temporary drain line rather than the liquid waste system.
This effluent path was not provided with a radiation monitor during the release. This change was made without the required evaluation.
This is an Infraction.
