STATUS
SUMMARY
G.
During the January, 1980 report period construction emphasis changed from the 1979 civil / structural efforts which were po'inted toward enclosing essentially all work areas,_to a mechanical /
electrical emphasis which will continue throughout 1980.
The vast majority of construction activities remained on or ahead of schedule during this reporting period and corrective action programs have been developed for those few areas that experienced schedule problems.
CONTAINMENT The installation of the reactor pressure vessel core plate and the drywell overhead liner plate were completed this month.
(
The erection of reinforcing steel and embedded pipe and conduit for the 803 foot slab on top of this overhead liner continues.
Modifications to the design of elevation 803 structural steel embed plates and the exterior of the drywell wall have been implemented to allow this steel to be installed prior to concrete placement.
The improved projected completion of this significant activity will further benefit the containment schedule.
This allows more work to be performed in parallel and will provide much needed laydown area inside the containment.
Work inside the drywell continues with the erection of structural steel platforms for elevation 759 feet and 768 feet underway.
The main steam isolation valves have been aligned to the drywell penetrations and weld out is in progress.
Construction of cantilevered slabs and walls outside the drywell continues.
Fuel pool cleanup pipi~ng is being installed onto the upper pool liners out of the hole to save c7nstruction
_c
- time and to reduce in-hole congestion.
?
FUEL BUILDING 4-6 Concrete placenent for the west portion of the slab at elevation 755 feet was completed this month as was condtruction of the temporary weather protection over the remaining. work areas for the floor.
The west exterior wall and the_ structural platform at elevation 781 feet are being expedited to allow cable tray erection which is required to support cable pulling to the screenhouse in April.
Pipe erection continues and will accelerate next month now that shoring removal and cleanup are completed for the entire basement area.
Cable tray hanger erection and the installation
{
of cable tray started this month.
AUXILIARY BUILDING Civil-structural effort during this report period concentrated on interior' walls ~and the mezzanine slab at elevation 755 feet, which had been originally bypassed to enable,an early completion of the roof slab.
Erection of large bore piping continues 'in the lower'three elevations of this building at the scheduled rate of installation.
The installation of sei.smic tray hangers is now under way at elevations 737 feet and 762 feet.
Construction of non-segregated bus in this building nears completion.

TURBINE BUILDING

The installation of siding interior sheeting is co plete on the south wall and in progress on the east and west walls.
Work on the heater bay walls has resumed with completion of the heater bay roof expected this summer.
Permanent plant equipment installation continues on or ahead of schedule in this building with such items as the generator lead box, iso-phase bus, 8 motor control centers, 14 instrument racks, drain coolers, and low pressure heaters being installed this month.
Installation and assembly of the 210 ton turbine building overhead crane nears completion, and the crane will be turned over to the Start-Up Group during February.
Large bore pipe erection continues and is on or ahead of schedule at elevations 712 feet, 737 feet, 762 feet, and 781 feet.
Small bore pipe installation is under way and proceeding at the scheduled rate at elevations 712 feet and 737 feet.
Cable tray erection continuce and is ahead of schedule at elevations 712 feet, 737 feet and 762 feet.
Conduit installa-tion is still proceeding and is ahead of schedule at elevations 712 feet, 737 feet, and 762 feet.
During February, some electri-cians will be transferred from this non-critical building to more important areas that will be ready for electrical activities.
CONTROL BUILDING During this report period, concrete was placed in areas which had been skipped over to facilitate an early enclosure i
- _ _ _. (,,
of this building, e.g., the HVAC slab at elevation 825 feet and interior stairwell walls at elevation 800 feet.
Concrete was also placed for finished floors at the battery and inbertor rooms at elevation 781 feet in anticipation of battery deliveries in mid-February.
At 800 feet, the control room elevation, installation of HVAC, and electrical hangers is under way to'aupport the fire-proofing of structural steel in February.
Additionally, the erection of doorbucks for masonry walls has started.
The. installation of large and small bore pipe continues 4
g
.c y,
and remains ahead of schedule at elevations 702 feet, 719 feet, 737 feet, and 762 feet.
Erection is also ahead of schedule for large bore piping at elevation 781 feet and for pipe hangers at b
elevations 800 feet and 825 feet.
Cable tray erection continues at an acceptable pace and is on schedule at elevations 702 feet, 719 feet, 737 feet, and 762 feet.
The installation of tray. hangers and tray is about 16 days behind schedule at elevation 781 feet.
Sufficient electrical supervision and craftsmen were obtained for the project during the month of January to institute a second shift in an effort to regain schedule.
Conduit instal-lation continues at elevation 702 feet and is currently critical.
The setting of equipment continues as required and this remains a non-critical activity.

,w
. DIESEL GENERATOR BUILDING h
Piping and cable tray installations are currently behind schedule in this building due to the late delivery of piping.
. Installation rates higher than-those utilized in the schedule are obtainable and schedule will be recovered as deliveries allow installation to be escalated.
RADWASTE BUILDING The installation of interior concrete walls around the solid Radwaste equipment at elevation 737 feet and concrete block walls I
at all elevations continue for this building.
Small bore pipe erection has commenced at elevation 702 feet.
Six instrumentation racks were set during this report period and kg, instrumentation for the makeup demineralizer system is virtually complete in support of a May turnover to the startup department.
Ten. permanent plant equipment pumps were installed during January.
Eighteen motor control centers and numerous motors were installed in the Radwaste Building during January.
Large bore pipe erection continues.and remains on or ahead of schedule at elevations 702 feet, 720 feet, 737 feet,'and 762 feet.
Small bore pipe installation is under way at elevation 702 feet and non-critical in this building.
Cable tray installation continues and is on schedule at eleva-tions 702 feet, 720 feet, 737 feet, 762 feet, and 781 feet.
Conduit erection is still proceeding on schedule at elevations 702 feet and 720 feet.

. SCREENHOUSE All work activities for the screenhouse remained on or are ahead of schedule this month.
Principal activity was concentrated on the erection of large bore pipe both above and below ground level, and the aligning, leveling and grouting of equipment.
YARD The demineralizer waste filter house was installed on its completed foundation during this report period.
The three main transformers and the spare main transformer were set on their foundation during January.
These transformers
{
are scheduled to be assembled and filled with oil by April.
