APPLICANT : DUKE POWER COMPANY FACILITY
- OCONEE NUCLEAR STATION, UNITS 1, 2 AND 3 E.ETING WITH DUKE AND B&W, NOVEMBER 27. 1973 BETHESDA, MARYLAND, RADIOACTIVE WASTE TREATMENT By letter dated October 26, 1973, Duke Power Company informed the AEC that during the operation of Oconee Unit 1, it has experienced difficulty in managing liquid waste generated by the station. The problem stems; from the fact that more liquid waste is being generated at the station than was anticipated at the time of the vaste handling system design, the system lacks the options required to effectively segragate clean from contaminated liquid and some of the liquid processing equipment is not performing up to specification.
Although the situation ha's been aggravating, it has not resulted in radioactive releases to the environment in excess of Technical Specification limits (See Enclosure 1). To assure meeting Technical Specification limits Duke Power has trucked apprcximately 117.000 gallons of very low level liquid from the station.
The October 26, 1973 letter from Duke also announced Duke's plans to add liquid waste processing equipnent to the existing system as an interim measure and to redesign the system as a permanent cure. The purpose of the meeting was to provide Duke the opportunity to nake a preliminary presentation to the AEC on these plans.
Duke described its experience to dato with liquid waste at the Oconee Nuclear Station during the operation of Unit 1.
The liquid waste sources which have made a major contribution to exceeding the design critaria of tho waste handling system are the sampling and laboratory drains, miscellaneous system leakage and the laundry. Although much of this waste has been clean, inability to segregate the clean liquid from the liquid which is slightly contaminated with baron and radioactivity has necessitated processing large quantities of the total. Furthermore, the wasta evapprator used to process the 11guid has not pefformed up_ _
to specification. Releasing liquid to the Keoves hydro ta'ilrace has been constrained by an unrealistic environmental Technical Specification limit on boron concentration. The==v4==

Technical Specifications it A.8 x 10 ppa,aboutafagtorof10,000 below natural backgroun va about a factor of 20 x 10 below the level which would affect fish. The staff recognizes this problem and is taking action to' correct the situation.
Duke described the interim measures that it plans to relieve the handling problems. These measures basically involve the addition of a parallel wasta processing system (See Enclosure II).
In addition, Duke is performing conceptual studies in order to design permanent modifications to the liquid wasta handling system. The staff advised Duke that the AEC would eventually have to find that the system is capable of meeting the objectives i
of Appendix I when it becomes adopted. Duke committed to providing the AEC with sufficient information, data and design criteria that the staff can perform an independent review of the permanent modifications.
{
The staff committed to responding to the Oc.tober 26, 1973 letter from j
Duke regarding staff review of the interim measures. Design information regarding the permanent modifications will be submitted by Duke about--
mid-Pebruary 1974.
