SUMMARY

OF CASELOAD FORECAST PANEL MEETING AND FACILITY TOUR AT MARBLE HILL, UNITS 1 AND 2

SUMMARY

On December 1, 2 and 3,1932 the NRC Caseload Forecast Panel (CFP) met with Public Service of Indiana (PSI) and toured the Marble Hill Nuclear Generating Station, Units 1 and 2. The purpose of the meeting and tour was to review construction progress and collect data for assessing the projected fuel load 'date for Unit 1. The visit was organized into two parts: 1 1. On December 1 a meeting was held with the applicant to review design and engineering, procurement and construction progress on Marble Hill, Units 1 and 2. 2. On December 2 and 3 a tour of the Marble Hill, Units 1 and 2 site was held to observe the _stctus of construction. In summary, the applicants expected dates for fuel load are June 1986 for Unit I and December 1987 for Unit 2. The CFP estimates that Marble Hill 1/2 will be ready for fuel load within approximately six months of this date. Due to abilities to modify construction schedules, a six mcnth differential within a three year projection of construction completion is sufficiently accurate to accept the applicant's fuel load date and schedule the staff's review. Data from this CFP visit will be compared to information gathered on subsequent visits to Marble Hill during construction. Should the CFP determine that Marble Hill Unit I will not be ready for fuel load within six months of the applicant's schedule, measures will be taken to resolve the discrepancy and adjust the licensing schedule if necessary.

? MEETING AND FACILITY T0bn DETAILS Wednesdav, December 1,1982 at MLrble Hill Nuclear Generating Station, New Washington, Indiana The CFP met with PSI at the visitors center on the Marble Hill site in New Washington, Indiana. The meeting was onen to public observers as stated in the meeting notice issued on November 16, 1982. A list of attendees is included as. The ap'plicants presentation to the staff was divided in eleven. parts correspond. ing to the eleven areas of information requested by the staff in the meeting agenda attached to the meeting notice. 'Beginning with a project overview PSI presented a list of major accomplishments in 1982. By November 15, 1982 the NSSS vessels were in place and loop piping had been started in the Unit 1 containment. The Unit 2 containment hip and dome had been set by October 23, 1982. A list of Major Accomplishments,1982 is included as Enclosure 2. The applicant reviewed the status of design a.nd engineering efforts for struc-tural, mechanical and electrical disciplines. On October 31, 1982 structural engineering was shown to be 89% complete for Unit 1. Mechanical engireering was 54% complete, and electrical engineering wa.s 48% complete. The overall engineer-ing effort was shown to be 64% complete for Unit 1. Similarly the overall engineering effort for Unit 2 was shown to be 38% complete. Structural engineer-was 87% complete, mechanical engineering has 27% complete and electrical engineer-ing was 31% complete. The applicant reviewed the status of design drawings. By October 31, 1982 99% of both structural and architectural drawings were released. 35% of all mechanical design drawings were released. More than 90% of most mechanical drawings were released, however, only 42% of hanger drawings were released. 54% of all elec-trical design drawings for Unit 1 and common facilities were released and 14% of electrical drawings for Unit 2 were released. PSI reminded the CFP that beca'use Marble Hill is a replicate of Byron the project establishes design criteria, prepares calculations and issues design information only for those features which are unique to Marble Hill. The applicant presented the status of procurement of valves, pipe, cable, cable trays, major mechanical equipment and major electrical ' u.ipment. Shipment of valves, cable and cable tray is scheduled to be completed in 1983. Shipment of other materials will be completed in 1985. -{

. PSI re;"ewed the Marble Hil'1 craft work force. Annual manpower averages for all crafcs were snewn for tne period from 1982 through 1938. The largest average work force of 2200 was shown for 1983. 2282 craft people were reported to be at Marble Hill on October 31, 1982. The applicant showed total manpower information for electricians, pipefitters and sheetmetal workers. Major craft manpower peaks for Unit 1 will De in 1934 and peaks for Unit 2 will be in 1986. The applicant indicated that there may be a shortage of electricians in mid 1984. Labor agree-ment expiry dates were shown with eleven of eighteen contracts scheduled to expire in 1983. The current status of large and small bore pipe hangers, restraints and ~ ~ snubbers was reviewed. PSI noted that the formal pipe hanger analysis for ~ Unit 1 will be complete by about March 1983. The analysis is resulting in a deletion of approximately 10% of the pipe hangers included in the previous preliminary analysis. 270 pipe whip restraints have been procured although 2" and "" diameter restraints have not yet been designed. The applicant esti-mates tnat approximately 35 of these restraints will be required for each unit based on the Byron design. Permanent snubbers will not be installed until late in the construction program. The ac;1icant employs a surrogate snubber program so that temporary snubbers are pla:ed to occupy space during construction that permanent snubbers will occupy. PSI reviewed the project schedule. Construction of Unit I was shown to be 43.8% ~ ccmplete wMie construction of Unit 2 was 25.7% complete. Overall construction is 37.8% complete. Project percent complete is shown in Enclosure for both units

SI reviewed project critical path items, identifying one critical path item '

3.and five potential critical path items. Tne auxiliary building, Area 5, Elevation 364' is -1/2 month critical path. - Tne auxiliary building, Elevation 383', Area 2 is potential critical path. - The containment large bore pipe, quadrant 3 is potential critical path., - Containment conduit design is potential critical path. - Loop piping is potential critical path. Mair control board delivery is potential critical path. p5I : resented the requested information concerning bulk n,uantities for Units 1 and 2-anc combined. This information is included in Enclosures 4, 5 and 6. The status of the Marble Hill preoperational test program was reviewed. 189 pre-108 are non-safety cperational tests have been identified for Unit 1 fuel load. related SOP, and 81 are safety related. The first preoperational test was sche-duled :o start on December 1,1982. Sixty-nine subsystems were released to ccnscruction test and 36 subsystems were turned over to the station. e

d 1. Thursday and Fricay. December 2 and 3,1982 at Marble Hill t<uclear Generating Station, New Wasninaton, Indiana The CFP toured the Marble Hill site on Thursday and Friday to observe the status of construction. Among the areas observed were the turbine building, the auxiliary building, Unit 1 containment building, the pipe fab shop and equipment laydown areas. The CFP's observations of construction activities were consistent with the infor-mation presented in Wednesday's meeting. E. L.
