SUBJECT:
SUMMARY
REPORT OF CASELOAD FORECAST PANEL MEETING WITH CEI AND FACILITY TOUR AT THE PERRY SITE Introduction On January 11,12 and 13,1983, the Caseload Forecast Panel (CFP) met with the applicant (CEI) and toured the Perry plant for the purpose of collecting data to assess the projected fuel loading date for Unit 1. The agenda followed is contained in Attachment 1. Because of the longer time projected by CEI for fuel loading of Unit 2 (May 1987), and the current stage of Unit 2 construction (approximately 457, complete excluding comon facilities) the CFP review concen-trated on Unit 1 and those facilities common to Units 1 and 2 essential to load fuel, test, and operate Unit 1. During the first day, interested members of the public were invited to observe the proceedings. A list of the CEI, CFP and members of the public in atten-dance is contained in Attachment 2. A tour of the facility was conducted on the second day of the following plant buildings: Unit 1 Reactor Building Intermediate and Fuel Handling Building Diesel Generator Building Auxiliary Systems Building Control Complex (including the Unit 1 Control Room) Service Building On the third day, the CFP met with CEI to further clarify data presented during the first day session, to pursue responses to questions raised during the tour, j and to separat'ely begin assessing its findings. l Summary of-Findings CEI's latest target date for Unit 1 fuel load, formally communicated to NRC in February 1982 and reflected in the Bevill schedule, is November 30, 1983. How-l ever, CEI is in the process of re-evaluating project schedules in light of the construction and test work which remains to be completed to determine a fuel load date. Based on its assessment of the information provided by CEI during 6', i-A - '- /.- vgy .e, .... I g
l,,. y } ( - the site visit, and the tour conducted of the plant, the CFP believes that the earliest possible date for Unit 1 fuel load is December 1984, and likely may be at a later date. The information provided by CEI upon which this finding is based is contained in Attachment 3, and is discussed in the section which follows. In view of the limited work currently on-going for Unit 2 and CEI efforts being concentrated on completing Unit 1, the CFP believes the earliest date Unit 2 could be loaded with fuel would be March 1988. On March 8,1983, CEI issued a press release announcing that the fuel load date for Unit 1 might be as late as December 1984. Cited as the basis for this change was the increased complexity of meeting continuing NRC requirements, TMI Action Plan Item modifications being incorporated into the base design, and its review of all construction work remaining to be accomplished. No mention was made in regard for Unit 2 construction schedules. Since the applicant's fuel load date change is consistent with the CFP's earliest possible fuel load date estimate, CEI's estimate is acceptable as the official Caseload Forecast date. Discussion of Unit 1 Construction and Test Data CEI maintains that as of December 31, 1982 work in the construction of Unit 1 and common facilities was approximately 89% complete. Based on a review of the work elements listed in the "Significant Quantities" t:ble in Attachment 3, the CFP finds that the construction activities (major system equipment, electrical and instrumentation work) remaining to be completed does not fully support this degree or percentage of work completion. About 20,000 li ! ear feet of large and 4 small bore piping welds in the Unit 1 Reactor Building remains to be completed. While this figure seems small in comparison to the 300,000 total small and large bore pipe work identified for this work element, significant work remains to be. completed involving the welding of 36-inch and 18-inch pipe which usually requires rework and is difficult to accomplish. Significant electrical work needs to be completed, primarily in the Unit 1 Reactor Building involving over 2,000,000 linear feet of cable, 120,000 linear feet of electrical conduit and 120,000 elec-trical terminations. Additionally, approximately 150,000 linear feet of instru-mentation work is incomplete involving tubing, valves, instrument and panel-racks. Furthermore, construction schedules for the large and small bore pipe and instru-mentation show this work being completed as late as March-April 1984 (reference the SP. 44/45 and SP. 33/34 schedule charts contained in Attachment 3). With respect to test work, of the total number of test activities scheduled -- 1992 identified by CEI as of November 1982 -- CEI indicated that 389 (19.5%) of the tests were completed and 547 initiated as of January 1,1983. CEI provided evidence of pre-test work performed early in the Perry project (prerequisite to ~ the conduct of pre-operational testing) which it believes increases the likeli-hood of a success-oriented pre-operational test program for Perry. Examples of the pre-test work completed and elaborated in Attachment 3 include: (1) the g n ~.. a
s_. -l _ creation of the Nuclear Test Section (NTS) 5-1/2 years ago ccmprised of CEI; GE (NSSS vendor) and consultants experienced in BWR pre-operational testing; (2) the early energization of electrical equipment and activation of the plcnts' permanent electrical power supplies; (3) the early operation and checkout of service and makeup water systems; (4) turnover of the Unit 1 Control Room to the NTS in 1980 from which all pretest and equipment test activities are being contro31ed; and (5) emphasis placed on identifying and inspecting equipment which proved problematic for other plants during pre-operational testing. How-ever, the CFP finds that much of the equipment test activities completed thusfar does not involve major critical-pat.n reactor systems. While the early pre-test work performed by CEI should help avoid program test delays, experience has shown that delays usually occur during major system equipment tests, and the problems encountered are often unique to a specific facility. CEI's pre-operational test schedules are considered to be somewhat optimistic since they do not allow for such contingencies; and considered in light of the construction schedules highlighted above, tne CFP believes that Unit 1 will not be ready to fuel load in November 1983. CEI acknowledged that the November 30, 1983 date will not be attained and is considering this in its schedule re-evaluation efforts. Conclusion Assuming that all remaining construction work is completed by March 1984, and that pre-operational testing can be successfully completed within nine months, the CFP concludes that Unit 1 fuel load could occur in December 1984. However, the optimisim built into CEI's current schedules suggest that fuel loading may occur at an even later date. Although a detailed review of Unit 2 facilities was not performed, when questioned about its status by the CFP, CEI advised that efforts were being concentrated on completing Unit 1. Since only a limited amount of effort is understood to be on-going for Unit 2, the CFP believes that the current fuel load date for Unit 2 (May 1987) is expected to slip by a time period comparable to Unit 1, with the earliest date for Unit 2 fuel load being March 1988. ,,,, LlI ( / lhd W N fohn J./Stefano, Project Manager / L'icensing Bfanch No.'-1 Divisipn f Licensing Attachments: As Stated cc: W.
