SUMMARY
OF NOVEFBER 19-21, 1980 CASELOAD FORECAST PANEL PEETING AND SITE VISIT the caseload forecast panel met with representatives On November 19-21, 1980, of the applicant (Mississippi Power and Light Company; and Middle South Energy, Inc.), their architect-engineer (Bechtel Power Corporation), and their NSSS supplier (General Electric Company) to review the construction and preoperational testing progress at the Grand Gulf Nuclear Station (GGNS) Unit 1 and to evaluate the most likely fuel load date.
The previous caseload forecast panel visit in August 1979 (report 12, 1979)
The forecast panel's estimate was inficenced by estimate of November 1980.(1) the length of time required for preoperatior.a1 testing, concerns about:
(2) the probable adverse impact on the test schedule resulting from final electrical work, and (3) unforeseen delays which may develop in the construction work that still must be completed.
The panel met at the construction site on November 19, 1980, and was briefed In the on the plant's engineering and construction status during the morning.
af ternoon, the panel toured the plant and inspected the status of construction On the following day the panel continued its tour of l

'JAN 2 2 19g3 The status of plant design, procurement, manpower, construction, startup pre-operational test program, resolution of 50.55e items, and the impact of recent licensing requirements are discussed below.
Plant Design Plant design is being performed by Bechtel Power Corporation, at both their Gaithersburg, Maryland offices and at the plant site. Overall design and engineering on Unit I and common facilities required for Unit 1 operation are estimated to be 98% complete, with essentially only electrical work remaining.
However, these estimates do not reflect engineering required for outstanding issues such as ATWS, TMI requirements, the Power Generation Control Complex, or rework. The applicant indicated that engineering is proceeding on these outstanding items, and is not expected to impact their fuel load schedule.
Procurement Procurement of bulk quantities appears to be in good shape and is estimated now to be above 90% overall. Procurement of 273 of 313 major purchase orders is complete, with delivery of the remaining incomplete orders scheduled for the first hal f of 1981.
Manpower MP&L described the construction work force activities and indicated that manpower availability for completion of Uni.t 1 should not be a problem. The current work force of about 1700 represents the full complement needed to complete Unit 1 and is not expected to increase significantly in the future.
In addition, centracts with local unions, many of which expire in mid 1981, contain no-strike agreements.
Construction MP&L described construction progress since the last forecast panel (August 1979).
They indicated that the current work scope has expanded from that previously estimated, and that the current estimate of 86% complete reflects an 18% workoff (1.2% per month) since August 1979. In order to support an August 31, 1981 fuel load with construction at about 96% complete, an average workoff rate of 1% per month would have to be sustained for the remaining 10 months.
22 M As indicated in Enclosure 3, concrete work is 99% complete. Large pipe Cable hangers and small pipe hangers are 90% and 80% complete, respectively.
trays have been completely installed. Wire and cable is 87% complete, conduit The required quantities of conduit 87% complete, and connection 79% complete.
and cable pulling have been increased over previous estimates, thus necessitating a substantial level of effort to complete these items within the current schedule.
A comparison of Grand Gulf cable pulling experience in 1980 with those quantities required in 1981 to meet the scheduled August 1981 fuel load date is provided in Enclosure 3.
Status and Resolution of 50.55(e) Items MP&L discussed the design deficiencies that have been identified and reported to the NRC pursuant to 10 CFR 50.55(e), and stated that these are being resolved and are not expected to impact the construction schedule. They indicated that the number of potentially reportable deficiencies reflects MPAL's cooperation in reporting this information to NRC Region II, rather than excessive deficiencies at Grand Gulf. Potential problem areas identified include:
(1) ventilation ductwork; (2) fillet welds; (3) QA related to reactor controls design; and (4) Hilti anchor bolts.
In view of the length of time a number of these items have been outstanding, the panel expressed a concern regarding their resolution and workoff so as not to impact the fuel load schedule.
Effects of Recent Licensing Requirements MP&L fndicated that they are actively pursuing implementation of recent TMI requirements, and that all items are expected to be implemented in accordance In addition, they expect no fuel load impacts with the required NRC schedules.
with respect to ATWS or environmental qualification requirements.
Startup Preoperational Test Program The startup preoperational test program and milestones were outlined by the applicant. In contrast to their previous estimate of 18 months, they now consider a period of two years, from plant energization in May 1979 until Although this compares favorable May 1981, sufficient to accomplish this program.
with an industry average of about 24 months, this may be misleading due to The app 1tcant indicated that the limited number of system turnovers to date.
the average number of turnovers is projected to increase from about 3.2 per i
The actions taken by the month in 1980, to about 10-15 per month in 1981. (1) combining the component applicant to achieve this improvement include:
turnover and startup groups to improve coordination and flexibility; (2) the formation of a turnover package group to increase administrative efficiency and (3) establishment of daily critical items meetings, held on-site, to id ntify and oversee critical path items.
JAN 2 2 1981 4_
The panel considers the preoperational test schedule to be the major delaying item for plant fuel load. Our reasons are as follows:
- 1) Recent experience with other plants indicates an industry average of about 5-7 system turnovers per month, whereas MP&L projects a turnover rate higher than this. Even a doubling of their past turnover rate would place the applicant's fuel load at about July 1982;
- 2) The applicant stated that a preliminary review of their preoperational critical path schedule indicates a possible delay in fuel load of about 2-3 months; and
- 3) The completion of remaining electrical work is likely to interfere with and delay preoperational testing.
Conclusion The applicant has made significant progress in actual construction since the last caseload forecast panel meeting, and is implementing aggressive managerial techniques to expedite component and system turnovers and reduce the number of punch list items. The applicant stressed the company's comitment to meet its predicted August 1981 fuel load date, but indicated that recent delays in system turnovers could result in a slippage of between 2-3 months. However, the panel feels this prediction is overly optimistic. Based on the panel's experience with plant construction and preoperational testing, using the same techniques that have been used to estimate the fuel load date for all other i
domestic facilities, and considering the general rework currently in progress and the final electrical work remaining, the panel estimates a fuel load date of July 1982.
In making this estimate, the forecast panel noted that, although not factored into this conclusion, there are several issues which could pottotially result in additional delays to the fuel load date. These include:
1) resolution of suppression pool hydrodynamic loads questions; 2) resolution of TMI requirements and ATWS issues; l
3) resolution of environmental qualification of equipment; and
- 4) impact of the Pilti anchor bolt design deficiency and resolution of other design deficiencies that currently exist or may arise in the future.
i
SAN 2 2 1981 i The panel further concluded that the estimated fuel load date depends on aggressive construction and preoperational testing progress, and high quality work and system turnovers. The panel stressed the commitment of the NRC staff to complete its licensing review in a timely but thorough manner so as not to delay plant operation unnecessarily.
