SUMMARY
During the July, 1980 report period, a comparison of per-formance to the project summary target schedule for fuel loah, some critical path activities lost 24 days to schedule.
One of the causes of slippage was the erection of electrical conduit in the containment building.
Corrective action programs are 11 -
being developed to improve the recently identified critical paths.
During this reporting period. manpower levels were above those originally proj ected. 'Overall productivity levels continue to remain above forecast.

3 [.'y CONTAINMENT Installation of reinforcing steel continues for the containment dome.
The first concrete placement is anticipated late in' August and the second lift to follow by approximately three weeks.
Work is also progressing on the overhead crane on' schedule.
Concrete N
placements on the walls to elevation 828 and the refueling floor at 828 is scheduled for coupletion by August'20. istructural steel erection at this elevation, including decking, will follow the completion of concrete work.~
The completion of this activity, along with the turnover of the polar crane, will provide laydown and handling capabilities for the limited access equipment needed prior to dome weldout.
Structural steel outside the dry well to elevation 803,
=<
- with the exception of crane areas, is scheduled for completion by late August.
As more areas become available, mechanical work outside the dry well will be accelerated.
Inboard and outboard isolation valves are set and valve welds are substantially complete.
Main steam and feedwater bellows are in. place and feedwater guard l
pipe erection is in progress.
Electrical work outside the dry l
wellcontinuesonelectricalpenetrations,[lightingandcommunica-IL tion, and cable tray hangers.
Inside the dry well, work is progressing on schedule on all major NSSS systems.
The Hydraulic Control Unit (HCU) module installation date has been changed from August 1 to mid October.

FUEL BUILDING Erection of the overhead crane in the Fuel Building was completed and turned over to the start-up function early in August.
Work is proceeding on the interior walls around the fuel transfer tube which is scheduled for completion in early September.
This will support the erection of the tube in mid-September.
Cable tray erection on elevation 712 is in progress and is scheduled for completion in late August.
Tray hangers are completed on elevation 737 and the installation of the trays at this elevation is schedul'ed for completion in mid-September.
AUXILIARY BUILDING Design revisions and associated material delivery problems k.-
continue to hamper a concentrated effort on the gas boundary steel installation.
Cable tray and conduit work continue on elevations 707, 762, and 781.
Erection of bus duct at elevation 737 is on hold due to lack of engineering solutions.
The instal-lation of piping hangers, along with large and small bore piping, continue on all elevations of this building.
TURBINE BUILDING Civil work nears completion in the heater bay area and the only remaining civil activities are the penthouses above slab at elevation 805.
Coating work is in progress on elevation 781 to prepare the area for piping and electrical work.
Initial alignment of the turbine crossaround piping is continuing with 36 of the 40 spools rigged in place.
Condenser tubing is now 94% complete and all the low pressure lower exhaust
. (. 4 -
hoods on the turbine are in place.
Low pressure lower inner casings are scheduled to be set in place in late August.
The installation of cable tray and hangers is essentially complete.
Work is continuing on the conduit installation and the pulling of wire and cable in this building.
CONTROL BUILDING We have currently received 18 of the 24 Power Generation Control Complex (PGCC) primary modules on site.
Installation of the panels is currently in progress.
Heating, Ventilating and Air Conditioner (HVAC) duct and hanger erection is under way on all elevations and is on schedule.
Bulk commodity installation continues for large and k$
small bore piping, cable tray and conduit, instrumentation and equipment, and wire and cable pulling.
DIESEL GENERATOR Piping and electrical operations continue with a small work force in this non-critical building as available resources are dedicated to more critical areas.
RADWASTE BUILDING Civil work continues in this building with the installation of siding on the elevator, penthouse, and the calibration room on the roof of the building.
All the panels except one in the Radwaste Control Center Room have been installed and welded in support of riser work in this area.
The HVAC work is essentially l

4 complete and a controlled access enclosure was built to protect b
the equipment.
Large and small bore piping and, hangers continue for all elevations of this building.
Also, conduit is being installed on all elevations.
i SCREENHOUSE Work in this building is primarily l'imited to erection of small pipe, conduit and HVAC.
Remaining grouting and equipment 4
sets are being restrained by deliveries.
SERVICE BUILDING The basement and substructure walls have been completed.
Structural steel erection is scheduled for completion in August.
Backfill w.ill begin after the completion of water. proofing.
. L-YARD Emergency Core Cooling System (ECCS) discharge pipe work i
is progressing ahead of schedule.
This will allow backfill to be completed by the end of September around the discharge pipe work.
All concrete activities are complete at the flume repair.
Flume backfill operations will be completed in August.
