SUMMARY
OF CASELOAD FORECAST PANEL EETING AND FACILITY TOUR AT COMANCHE PEAK Summary On April 13,14 and 15,1982, the Caseload Forecast Panel (CFP) met with the applicant and toured the Comanche Peak Steam Electric Station, Units 1 and 2 for the purpose of collecting data for assessing the projected fuel loading dates for these. two nuclear units. The visit was organized into two parts; 1.
A meeting with the applicant to review design and engineering, procurement and construction progress. Progress on prerequisite testing and preoperational procedures and testing was also revi ewed.
(First day) 2.
A tour of the station f acilities to observe status of construction.
The CFP also held discussions, with the NRC Resident Construction Inspector and NRC Resident Operations Inspector.
(Second and third day)
In sunnury, the applicant's target dates for fuel loading Unit 1 is June 1983, and for Unit 2 is December 1984. The CFP believes that the fuel loading date for Unit 1 could be in December 1983. The CFP estimates that the fuel loading date for Unit 2 is approximately 16 months later.
The data upon which our projections are based is given in the followi.ng sections of this meeting summary.

JUL 7 1982 Mr. Burwell opened the meating with introductions and a statement on the purpose of the treeting.
The staff noted that it is still NRC practice to schedule OL reviews indexed to the applicant's dates. Therefore, the CFP projected dates take on less significance than in the past.
The agenda for the meeting was enclosed with the Meeting Notice noted above.
The applicant's presentation on the status of engineering, procurement and construction was led by Mr. J. B. George. Mr. George advised that construction on Unit I was 86 percent complete and construction on Unit 2 was 46 percent complete.
Fuel loading dates for Unit 1 and Unit 2 are targeted for June 1983 and December 1984 respectively. Major milestone dates for construction are shown on Enclosure 2.
The applicant has scheduled the hydrostatic test of the reactor coolant system for late June 1982. The Unit 1 turbine is now on its turning gear.
Many of the process systems are undergoing flushing and cleaning.
Electrical systems are energized. Of 298 subsystems necessary to operate Unit 1, construc-tion has turned over 193 subsystems to the startup group.
The installation of pipe hangers and restraints on Unit 1 are nearing completion and delays associated with this effort are a thing of the past. Mr. George noted that construction on Unit 2 was progressing smoothly and rapidly because of.
lessons learned on constructing Unit l.'
Mr. George stated there were no antici-pated problem areas which will delay fuel loading past the applicant's projected dates on either Unit 1 or Unit 2.
The engineering for the basic Unit 1 design has been complete for some time.
Engineering is now limited to the new requirements imposed by NUREG-0737 and resolution of interferences. The applicant's objective is to execute all NUREG-G737 requirements prior to loading. fuel in Unit 1.
The principal engineering effort on Unit 2 is over; the basic design is over 90 percent complete. The larg2r engineering activities are the design review of site generated design changes and the design of piping supports and restraints.
1 Procurenunt on Units 1 'and 2 is nearly complete. The only problem areas relate to additions to the uninterruptable power supply, radiation monitors, and sump and flood level instrumentation. ThE' equipment for the Technical Support Center and Emergency Offsite Facility wil.l..be delivered by Summer 1982.
l There are presently 4800 people working on construction of the site. They work 5 days a week,10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> a day. Two shifts are operational, with about 700 people working the back shift. About 1000 of the construction people are working on Unit 2, this will increase with time as Unit 1 nears completion.
The present l
craf t work force consists of approximately 1,460 mechanical, 850 electrical, 60 instrumentation and control, and 880 civil workers. These will increase slightly until December 1982 and then decrease as Unit 2 nears completion.

The status of construction on.both Units 1 and 2 is summarized by the bulk conmadi ty comparison Table, Enclosure 3.
For Unit 1 structural concrete and piping and hangers are 93 percent or greater completed and wire and cables are greater than 75 percent complete except for security and lighting.
For Unit 2, structural concrete is 99 percent complete, large pipe is 60 percent complete, and small pipe, pipe hangers and electrical wire supports are roughly one-third complete. Little of the Unit 2 wire and cable has been installed at this time.
Mr. George summarized the status of construction of Unit 1 by describing an area analysis of scheduling status. Each building is reviewed for the work remaining to support a target fuel load date of June 15, 1983 for Unit 1.
All buildings are o.n schedule except the reactor building which shows a 32 day criticality (days to be recovered in order to meet the target date).
Since the previous CFP visit the applicant has made a decision to complete major construction activities in the Unit 2 control panel and cable spreading room areas prior to the fuel loading date for Unit 1.
Construction in this manner eliminates the need for a security barrier between these portions of the control building during completion of Unit 2.
This decision has added considerably to the wire and cable quantities which must be installed prior to Unit 1 fuel loading. Nevertheless, the work remaining in the control building is on schedule for a June 1983 fuel loading date.
The applicant's presentation on the status of the preoperational procedures, system turnover to the startup group and preoperational testing was led by Mr. Dick Camp. The status of preoperational procedures preparation is shown in the following table:
Preopsl Accept 2 Total Total test procedures required 135 41 176 Draft procedures not started 43 4

The status of system testing was discussed. The construction group must turn-over 298 subsystems to the startup group for prerequisite and preoperational testing. The startup group has accepted 193 subsystems at this time. However, nearly all of subsystems have a list of items (punch list items) which must be resolved before the system is complete. The punch list for included subsystems
~
_4_s JbL
'? 1982 mst be essentially resolved before preoperational testing of a system can bega n.
Preoperational testing is expected to start in late June 1982.
The startup group is currently staffed at 45 startup engineers. The applicant expects this group to peak at about 68 startup engineers at the end of the year and remain constant through the third quarter of 1983.
The applicant reviewed the list of open potential deficiencies which were reported to the NRC in accordance with the requirements of 10 CFR 50.55(e).
The applicant does not expect any of these to impact the June 1983 fuel loading date.
Wednesday, April 14, 1982 at Comanche Peak Steam Electric Station, Glen Rose, Texas The CFP observed constnJction progress in the Unit 1 containment building, Unit i safeguard building, Unit 1 diesel generator rooms, and fuel building.
All large equipment items are installed. Most of the large and small piping is installed and complete. Many of the systems are running. Most of the pipe supports are installed. Most of the cabling is installed except that some of the cabling inside containment is not terminated.
The CFP met briefly with Mr. Dick Camp to review several documents that were not available at the April 13, 1982 meeting. The CFP inspecte,d the Master Systen Punchlist, a computer printout sheet, to gain insight into the number, nature, and scope of unresolved items remaining in the subsystems accepted by the startup group.
The CFP also inspected a documnt entitled Summary of CPSES Startup Program to gain insight into the organization and planning for the startup program.
The CFP interviewed the NRC Resident Construction Inspector, Mr. R. G. Taylor, and the NRC Resident Operations Inspector, Mr. D. L. Kelley during the April 14, 1982 facility vi sit. Mr. Taylor confirmed the general status of construction as presented by the applicant and observed by the CFP. Mr. Kelley confirmed the general status of preparation of operational procedures and conduct of testing operations by the startup group as presented by the applicant.
Thursday, April 15, 1982 at Comanche Peak Steam Electric Station, Glen Rose, l
The CFP observed construction progress in the Unit 2 containment building and in the auxiliary building, particularly in the control room and cable spreading rooms.
Construction is proceeding rapidly on Unit 2.
The applicant has made l
i l
a.
. JUL 7 1982 provisions for mounting pipe. hangers and restraints by embedding large numbers of studs in the walls throughout the Unit 2 containment. The installation of piping, piping hangers and cable trays appears well planned-and proceeding ef fici ently.
The control panel for Unit 1 is energized with many controls, instnaments and alarms functioning. The applicant has initiated a program to rework the control panel to reflect the results of its human factors review of the control room.
The applicant does not expect this to delay the June 1983 target fuel loading da te. The Unit 1 cable spreading room has a few empty cable trays, but most of the cables are in place.
The control consoles for Unit 2 are sitting in place, but there has been little or no wiring installed between the consoles and the Unit 2 cable spreading room.
The Unit 2 cable spreading room has the cabinets set in place and most of the cable trays are installed.
There are few if any cables installed in the Unit 2 cable spreading room.
Summary The CFP reviewed the status of constnJction on Units 1 and 2 and the status of the preoperational testing program for Unit 1.
The bulk of construction on Unit 1, and associated stnictures and systems needed to operate Unit 1,-
is approaching completion. The preoperational testing program for Unit 1 is expected to start in June 1982. Construction on Unit 2 appears to be proceeding efficiently.
Considering the status of construction and the preoperational testing program, the CFP believes the fuel loading date for Unit 1 could be in December 1983 provided no major delays develop during preoperational testing. The CFP estimates that the fuel loading date for Unit 2 is approximately 16 months later.
