SUBJECT:
SUH4ARY OF CASE LOAD FORECAST PANEL SITE VISITS OF i.....-
JUNE 13,14 AND 15,1978
@y F sy Representatives of the NRC's Case Load Forecast Panel met with represent-W atives of the Washington Public Power Supply System (WPPSS) at the WPPSS
'E offi o s in Richland, Washington, and at the project sites on the Hanford
- c %
Reservation approximately 10 miles north of Richland.
Background
{
During the past several months, members of the NRC Case Load Forecast 1b Panel have visited several nuclear plant sites to assess the status
.9 of construction and to evaluate the applicant's projected construction t
completion dates. The objective of these site visits, is to provide LD the panel with an oppor tunity to evaluate the applicant's present
, ;C) status of construction and to use that information to predict construction XM completion dates bas 2d on our experience with construction times at other nuclear stations. The WPPSS project visit was one of these scheduled fS, series of meetings.

Summary

A generalized presentation by WPPSS of the WPPSS construction program 41l?
W-T was given on 6/13, in the WPPSS offices in Richland, followed by more specific sumnaries of each of the WNP-1 and WNP-2 project efforts.
p&cy Appropriate senior management officials of WPPSS made the prasentations
@f pf and responded to questions posed by the panel members. The enclosed

WNP-l_
(N$
J. Thomas, WNP-1/4 Project Manager, stated that WNP-l was about 11.5%
, 4:..
complete as of May 26, 1978, some two years and nine months after receiving a Limited Work Authorization in August 1975. He described the official af WPPSS schedule that would require a completion rate of about two percent
- , f.
per month for the next 40 months in order to reach 90% completion twelve
~-
months prior to the planned fuel load date of June 1982. Commercial operation is scheduled for December 1982. WPPSS plans to submit the Final Safety Analysis Report for operating license review in December 1979.
{i-Several other scheduled milestones are:
Set reactor vessel May 1979 Begin test & startup program December 1980 Hydrostatic test NSSS November 1981 The engineering for WNP-1 was reported to be approximately 90% complete.
The project manager receives weekly reports on construction progress, in his meeting with area specialists. At the WNP-1 site, specialists were available to discuss progress in each of five major construction activities:
lk.
Civil and structural Electrical Piping Mechanical Instrumentation and air Percent completion of individual work activities is measured by emplaced material or otherwise actually completed work. The overall project critical path is identified monthly with a computer program designed to
{-
monitor schedule progress.
{
Based on our evaluation of the information presented by WPPSS on the status of constnJction, staff discussions with WPPSS representatives, and the construction site visit, the NRC Caseload Forecast Panel staff members felt that WPPSS had been somewhat pessimistic in their estimate
'~
of percent completion and that as of the date of our visit the figure was nearer 20%. On that basis, and assuming a construction progress
.I l " "I rate of 1.8% per month until the 90% ccmpletion point is reached, the N
WNP-1 fuel load date would be reached about September 1982. We believe that the WNP-1 project schedule should be critically examined
' Q.4 again in March 1979 to update the current projections.

WNP-2
'y A. Kohler, WNP-2 Project Manager, stated that WNP-2 was about 60% complete at the date of this meeting. The current projected fuel load date is 7-March 1980. Mr. Kohler stated that a number of significant changes in the b_
project organization within the past year, as well as changes in the WPPSS' method of contracting, had made it possible for WPPSS to move more rapidly
('
toward project completion. One such improvement was the consolidation of n..
the site staff organizations of Burns and Roe and WPPSS personnel.
- Further, w'
the construction force has been working three shifts since early 1978. The critical path for completion of construction work has been identified as n1 the reactor building and particularly the drywell within that building.
[,N The reactor is a BWR having a Mark 2 containment. WPPSS believes that they p.1 -,
will meet all postulated containment design load requirements with the p,-
~
design improvements they are now incorporating into the containment, even e
though the final load definition will not be formally approved by NRC until sometime in 1979.
Some specific construction activities in which WPPSS acknowledged delays are-installation of' exposed conduit, wire and cable, large bore pipe
- i..
hangars, and cable terminations.
L; L: J.
@f; -
Startup testing plans described by WPPSS showed a 20 to 24 month effort starting approximately 10 to 12 months prior to the planned cold hydrostatic test in approximately July 1979, and continuing through the g ~..
planned fuel load date in March 1980. The assigned startup program
- 6. ",
manager has had extensive experience having " started" six other BWR plants.
P..
kWP The NRC Caseload Forecast Panel staff conclusions concerning the WNP-2 Q
schedule were based on information presented by WPPSS, discussions with dW WPPSS and Burns and Roe representatives, and the site visit. We concluded M
~
that the applicant's assessment of the time necessary to reach the 90%
hsY' completion status, i.e., March 1979, was optimistic. As a result, the
- k applicant's construction completion target date of March 1980 should be i
considered the earliest possible date.
The Caseload Forecast Panel
,;j considers that an appropriate estimated completion time would be nine WB
[w.ff,j J1 to twelve months later, from December 1980 to March 1981.
