SUMMARY
During the August, 1980 report period, a comparison of per-formance to the project summary target schedule for fuel load-indicates some critical path activities lost 23 days to schedule.
One of the causes of slippage was the erection of electrical conduit in the containment building.
Corrective action programs are being-developed to improve the recently identified critical paths.
During this reporting period, manpower levels were above those originally projected.
Overall productivity levels continue to remain above forecast.

,s-CONTAINMENT Installation of reinforcing steel continues for the containment dome.
The first concrete placement has been completed and the.
second lift is now scheduled for October.
Due to alignment and problems with the crane rail girders, electrical installation of conductor has now been scheduled to start the first week of October.
+
Other electrical work connected with feeder conduit and hangers to elevation 856 is in progress.
Concrete placements on the walls to elevation 828 was completed in August and structural steel i
erection at this elevation is in progress.
Preassembly work on the fuel transfer tube and work on other necessary limited access equipment is in progress prior to dome weldout.
(,,
Structural steel outside the'drywell has-been completed.
As a result, mechanical work outside the drywell is accelerated.
Inboard and outboard isolation valves are set and welded in place.
Work continues on feedwater guard pipe erection.
Electrical work
.outside the drywell continues on electrical penetrations, lighting i
and communication, and cable tray hangers.
Inside the drywell, work is progressing on schedule on all major NSSS systems.
Reinforcing of structural steel inside the drywell is being evaluated.
FUEL BUILDING The final section of the roof was completed this month.
With i
this pour the roofs on all main power block buildings are complete.
