(m 5-OCONEE NUCLEAR STATION PERMANENT WASTE MANAGEMENT FACILITY
.g
._. s,
, c.o In October 1973 Duke Power Company (DPC) informed the staff via as Unusual Event Re art that the liquid and gas waste management systems at Oconee were procw sing larger volumes than were estimated in the FSAR.
DPC indicated that they would design and install an Interim Waste Laagement Facility to assure they had sufficient capacity to accennodate Oconee Unit 3 which was not yet operating. They indicated that ainee it was to be an interim facility and the estimated date of completion was May 1974, the design may not be in accordance with all design criteria and code requirements which would be provided in a permanend facility. Their preliminary plans. indicated a need for additional permanent waste manage-ment facilities and would require a separate building to house the facilities._ This building was to be designed in accordance with criteria consistent with that for the existing w wte management-system. Conceptual studies and tests were to continue to improve the operation of the existing installed systems.
7 In a November 1973 meeting, we advised DPC that we would eventually have to find that the permanent systems are capable of meeting the objectives of Appendix 1.
DPC cocmaitted to providing us with sufficient information, data and design criteria to allow us to perform an independent review of the permanent modifications.
In a December 1973 letter, we acknowledged, in effect, that the plans to install an interim far.ility would be acceptable, but the changes-should be reported in the First Tear Operating Report and the next Semi-Annual Report. -- However, since DPC planned to have the interim system in operation before Unit 3 startup, we requested that they provide an interim report describing the interim facilities at least 60 days prior to Unit 3 fuel loading.
By lecter dated May 2,1974, DPC provided a report describing the Interim Waste Management Facilities.
(Not formally reviewed by us)
In the Semi Annual Report for the period ending December 31, 1974, DPC described the Interim' Waste Management Systems and, pursuant '.o 10 CFR 50.59 implied that no.unreviewed safety questions were invo7ved.

the permanent facilities to update the Environmental Technical Specifications.
l By latter da ed' June 23, 1975 DPC indicated that, with several design l
modifications, the interim facility would be acceptable for permanent use.
They enclosed a safety analysis report describing the design objectivas and criteria applied to the final design of the permanent facility.
In August 1975. ETSB indicated they thought it necessary to conduct a We issued a TAR to ETSB formal review of the planned permanent facility.
to determine if we agreed that no unreviewed safety questions are involved.
+
In February 1976, ETSB advised that other branches should be included in the review.
s In April 1976, we issued a second TAR to EB, EEB and PSB to evaluate the wtreviewed safety question issue. Personnel from EB advised that certain areas pertinent to the new rad waste building had not been revi. awed in the PSAR reviewand should now be looked at.
The Geology-Seismology branch was specifically mentioned.
The present indications are that the permanent waste managenent facility design includes unreviewed safety questions that should be reviewed by the Commission before DPC is alle '4 to continue with their plans for modification.
