SUBJECT:

SUMMARY

OF SITE VISIT BY CASELOAD FORECAST PANEL

?r u

',, ? r d f On June 8-10, 1982, the Caseload Forecast Panel made a visit to the St. Lucie

_9 plant site to assess construction progress.

(A previous visit was made in

" N October 1980). The visit initially included a presentation of cestruction status by the applicant (the Agenda is shown in Enclosure 1) followed by a tour of,the construction site.

A summary of the Panel visit is presented below.

Summary The applicant made a presentation on the statds of construction. The presenta-tion covered each of the Agenda items shown in Enclosure 1.

At the meeting, the applicant continued to project a fuel load.date of October 28, 1982.

However, the applicant stated that it was in the process of reassessing its 1

schedule to integrate the construction activities and the testing and startup phases into an overall schedule. The applicant expected to complete thi.s assessment in a few weeks.

After the presentation *,,we toured the facility.

As a result of the presentation and tour, we learned the following:

As of May 1982, overall construction was about 88% complete.

Power q

cable installation was about 88% while terminations were about 90%, 60%,3 and 32% complete re,spectively. Construction activities were still in progress in the control room.

u-a 23;. M Of the 305 subsystems,in the plant, 241 had been transferred from n.

j construction to prerequisite testing. Seventy-four of the systems had been released to startup (for preoperational testing).

9 The total = number of preoperational procedures required for fuel load-C[,iJ ' '

are 170. Of these 125 were approved for use.

Fifteen of the 170 preoperational tests had been completed.

After returning to Bethesda, we performed an assessment of the status of yj ~

tW construction and informed NRR management of our findings. Based on this assessment, we concluded that the fuel load date for Unit 2 would be later J.'t.3 than the applicant's projected date.

'j-on the status of the preoperational test program.This conclusion was based t t.d E assessment, we verbally informed the applicant of our findings.Upon comp f

At the end of June 1982, the applicant's schedule for Unit 2 shows a slip of 14 weeks as reported in their "St. Lucie Unit 2 Construc

'"d Startup Monthly Status Report" which was transmitted to the NRC +y F us!

SUMMARY

OF MEETING HELD ON OCTOBER 15-16, 1979 REGARDING THE FORECASTED FUEL LOAD FOR THE SUMMER FACILITY On October 15-16, 1979 we met with representatives of the South Carolina Elec-tric and Gas Company (SCE8G) 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 Summe would be ready for fuel loading.

in Enclosure 1.

In the applicants' presentations, a large number of overhead slides were used, After the copies of the slides can be obtained from the project manager, initia 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 Sumer facility was approximately 90 We estimated that the plant plete.

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 theA sum review of the Sumer Final Safety Analysis Report (FSAR).

points in the meeting and the bases for our conclusions are presented below.

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.

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 precperational testing programs, the applicants provided progress / trend curves for the procedure approval and for the start of testing in various categories.

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 number of test starts per week required by the schedule.

Af ter 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 We based this conclusion on the following:

November 1980 and February 1981.

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.

The startup preoperational testing program appeared to be behind schedule.

2.

Although they had recently completed several long, time-consuming tasks, it was not evident that they could meet the high rate of 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 However, if the review schedules cannot be improved for these areas; the 1980.

Our reassessment of fuel operating license decision date would be much later.

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 summary, 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.
