SUBJECT:
SUMMARY
OF MEETING HELD ON OCTOBER 15-16, 1979 REGARDING THE FORECASTED FUEL LOAD FOR THE SU mER FACILITY On October 15-16, 1979 we met with representatives of the South Carolina Elec-tric and Gas Company (SCE&G) and South Carolina Public Service Authority (Santee Cooper) at the site of the Virgil C. Summer, Unit No.1 (Summer facility).
The purpose of the meeting and subsequent tour of the Sumer facility was to gather information for an independent assessment of when the Summer facility would be ready for fuel loading. The persons attending the meeting are listed in Enclosure 1.
In the applicants' presentations, a large number of overhead slides were used, copies of the slides can be obtained from the project manager, After the initial presentations, the caseload / forecast panel toured the facility; caucussed with the IE resident inspector and the IE principal construction inspector; and discussed our conclusions with the applicants.
In brief, we were in agreement with the applicants that the Summer facility was approximately 90 percent com-plete. However, the Caseload Forecast Panel (CFP) concluded that the applicants' fuel load date of July 1980 was too optimistic. We estimated that the plant would be ready for fuel loading between November 1980 and be February 1981. We also discussed the significance of this conclusion on the priority given to the review of the Sumer Final Safety A,'alysis Report (FSAR). A sumary of the major points in the meeting and the bases for our conclusions are presented be'ow.
Status of Engineering, Construction and Pre-operational Testing The engineering for the facility is essentially complete. The only exception were the radwaste solidification system and design verification for Class 1 supports. This design verification revealed an error in the coordinate system used in the seismic analysis; the analysis effects 173 Class I hangers.
With regard to construction, the applicants estimated that the facility was 91 percent complete as of September 30, 1979. The next major milestone is the cold ttydrostatic test of the primary system; it is scheduled for 11/18/79. Tne cold hydrostatic test for the secondary system was completed in September 1979.
The status of various bulk quantities are given below:

The craft work force at the site was about 1500 workers, exclusive of subcon-In most areas, there was only a single shift, however, critical tractors.

The pipe hanger status varied from one area in the plant to another. Of par-In the ticular interest to the CFP was the status in the reactor building.
reactor building the larger hangers are 37 percent complete and 1057 out of 1514 remain to be completed; and the small hangers are 49 percent complete and 652 out of 1278 remain to be completed. The applicants stated that of the 1057 large hangers and 652 small hangers many were in various stages of completion; many would not be completed until after hot gap setting was done after hot functional testing.
With regard to the electrical area. The applicants stated that the bulk of Work the work remaining involved the containment electrical penetrations.
on terminations at these penetrations did not begin until September 1979.
Construction personnel had identified 523 mechanical subsystems and 2737 electrical subsystem for the purpose of monitoring the status of subsystemThe turnover to operations personnel responsible for preoperational testing.
graphs of the turnover schedule indicated that construction was one to two months behind in the turnover of these subsystems.
With regard to the status of preoperational testing programs, the applicants prov:Jed progress / trend curves for the procedure approval and for the start of testing in various categories.
1381 353
071g79 The CFP was very interested in the progress / trend curve for the development and performance of startup pre-operational procedures.
The curve is enclosed to this summary as Enclosure 3.
The progress / trend indicated to the CFP that the applicants were about to fall behind in the starting of startup tests.
Further, the applicants had not demonstrated that they could achieve the high nurrber of test starts per week required by the schedule.
After the site tour, the CFP caucussed and presented its conclusion to the applicants. The CFP concluded that the plant would be ready for fuel load between November 1980 and February 1981. We based this conclusion on the following:
1.
The installation of pipe hangers in the containment and electrical termin-ations at containment penetration would not occur as quickly as scheduled because of the nature of each task limited the manpower that could be used.
The completion of these items would not delay cold hydro of the primary system, but would delay hot functional testing and fuel load.
2.
The startup preoperational testing program appeared to be behind schedule.
Although they had recently completed several long, tinoconsuming tasks, it was not evident that they could maet the high rate
, test starts demanded by the startup schedule.
We then discussed the impact of this conclusion on the priority assigned to the review of the FSAR. We stated that previously the Summer FSAR had been given a relatively high priority when compared with other facilities previously expected to be ready for fuel loading in 1980. The rescheduling of non-Three Mile Island related activities indicated that with the exception of two review groups, reactor systems and geology / seismology, the Safety Evaluation Report could be issued in March 1980 and an operating license decision reached by late 1980. However, if the review schedules cannot be improved for these areas; the operating license decision date would be much later. Our reassessment of fuel load date from November 1980 to February 1981 would probably not affect the priorities already established because we anticipate that as we reassess the fuel load dates for the other facilities, we will find that their final load dates would also slip.
In sunmary, we concluded that it was as toss up as to whether licensing or completion of construction and pre-operational testing be limiting for fuel load.
In the applicant's closing remarks, they stated that they would look at the problem areas that we had identified, but that they remained confident that a fuel load date of July 1980 was achievable.
