E K6 STATUS
SUMMARY
During the February, 1980 report period, construction emphasis continued the transition from the civil / structural w
efforts to enclose the buildings'to a mechanical / electrical emphasis.
Well over half of the craftsmen currently on the
- project are now involved in mechanical,- piping,j and electrical work.
Both manpower and productivity levels remained near projections and therefore the vast majority of. construction
' activities are currently on or ahead of schedule.- Those items experiencing schedule problems should begin to show results from the implementation'of corrective action programs later this spring.
CONTAINMENT
{..
The major achievement in the containment building for this report period was placement of concrete for the elevation 803 feet slab.
This allowed installation to begin on the remaining upper pool liners, and reinforcing steel inst'allation to commence for the walls up to the re~ fueling deck at elevation 828 feet.
Installation of the 803. feet elevation

c ctructural steel has been completed for the suppression pool annulus and decked over to provide additional lay down and work-area inside the containment building., Structural steel for the drywell. annulus platforms at elevations 759 feet and 768 feet
'wereLdelivered to the site with significant misfabrications.

(See problem area discussion for details.)
The main steam A and
+
D. loops have been aligned and final weldout of both isolation valves to the drywell penetrations has been completed.
Align-ment of the remaining two main steam loops is in progress.
The installation of electrical pull boxes, thermocouples, and conduit supports is in progress under the reactor pressure vessel.
Incore work continues in the vessel.
FUEL BUILDING Lower fuel pool liner alignment difficulties were resolved this period and on February 22, concrete was placed for the final fuel pool wall, thus freeing all remaining civil work in this building.
The installation of form work, rein-forcing steel, embeded pipe and conduit continues for the slab at elevation 755 feet.
The west exterior wall has been completed up to elevation 781 feet and erection of structural steel has commenced on the west side.
This work is being accelerated to support cable tray installation required for cable pulling to the screen house this spring..In the basement, at elevation 706 feet, the removal of shoring and cleanup was completed to allow an accelerated effort on the installation of large bore piping, and seismic cable tray hangers.
The installation of cable. trays has started in the bas.ement and large bore piping installation is underway at elevation 737 feet.

v-J AUXILIARY BUILDING Construction of interior concrete walls at elevation 737 feet, which were originally bypassed to enable an early completion of the roof slab,were completed and erection of shoring for the elevation 750 feet mezzanine slab is undeyway.
Erection of structural steel for the gas boundry. liner was completed at elevation 762 feet and is underway at elevation 737 feet.
The installation of large bore piping and seismic tray hangers and cable tray continues on the first three elevations of this building.
Worker density in this building for mechanical and
. electrical items is uncommonly high and has been affected by
(
the civil work at elevation 737 feet.
Switchgear rail instal-lation is in progress at elevation 762 feet.
Two unit substations were set in place at this elevation.
The installation of conduit is progressing in the lower two elevations of the building.
TURBINE BUILDING Erection of all siding and roofdeck is complete and
.:v.
p.mv
. e, ; > v the application of permanent roofing is in progress. g m. Foundations for major pieces of limited access equipment are being prepared for equipment placement next month.
The.210 ton turbine building overhead crane.was energized, load tested, and is now in use as a construction crane.
Work on the condenser continues and the tubing operation should begin in March.
In preparation for turbine erection, work on the sole plates has begun.

of 'large bore piping continues at all elevations and small bore pipe erection continues in the lower three elevations. Erection of main steam and feedwater pipe supports is underway and_the installation of condensate pump monorails has been completed.
Four area coolers were installed at elevation 762 feet.
Cable
(
tray hanger and tray erection continues for elevations 712 feet, l
737 feet, and 762 feet.
Erection of exposed metallic conduit for power and control cable continues on elevation 712 feet and 737 feet.
The generator lead box is being welded out.
Instal-lation of the two stator coolant pump motors was completed as was the installation of C instrument panels.
All work activities in this building are ahead of schedule and during this report period some craftsmen were
%s transferred to more critical buildings.
CONTROL BUILDING Construction of the HVAC and elevator penthouse walls is in progress on the roof slab at elevation 747 feet.
Installation
-of the elevator should commence in April.
At elevation 800 feet, the. control room, installation of HVAC, and electrical hangers was completed and fireproofing of the structural steel has commenced.
The installation of large and small bore pipe continues and remains ahead of schedule for the first five elevations of this building.
The erection of pipe hangers continues on the top two elevations of the control building.
Cable tray hanger ss and tray installation continues at an acceptable pace throughout the building except in the cable spreading room at elevation 781 feet.
(See problem. area discussion for details.)
o l !
.(. '
The setting of equipment continues and remains a non-critical activity.
DIESEL GENERATOR BUILDING Construction of the unit 1 diesel generator foundations was completed this month.
These units are expected to be delivered in June.
Concrete was placed for the tunnel walls-on top of the building roof this month, however, the. tunnel roof will not be poured until the large diameter limited access piping spools are delivered and can be installed.
This is not a high priority area.
The delivery and installation of the above.
stated pipe is not critical.
The installation of large and small bore piping continues at all elevations.
Two hydrogen recombiners and four area coolers were installed this month.
Cable tray and conduit installation continue on schedule in the lower three elevations of this building.
RADWASTE BUILDING t
The installation of interior walls around the solid radwaste equipment continues at elevation 737 feet witk the -
final concrete placement scheduled next month.
Construction of block walls continues at all elevations in support of and coordination with piping, electrical and mechanical operations.
L
~~
j
, The installation of condenser vacuum pump tanks and heat exchangers, and the radwaste processing condensers and sub-coolers was completed at elevation 762 feet.
Fourteen motor control centers and four unit substations were installed at elevation 762 feet.
Eleven instrument panels ~were installed at 702-feet and 737 feet.
Erection of large and small bore piping continues and remains non-critical at all elevations of this building.
The installation of tray hangers, cable tray, and conduit continues at an acceptable pace.
However, some small portions of this electrical work are critical for the turnover of early piping systems.
t SCREENHOUSE Activities for the screenhouse remain on or ahead of schedule as of this report period.
Principal activity was concentrated on the erection of large and small bore piping,
~
cable tray and conduit, and aligning equipment.
YARD
.r Demolition of the. concrete pads utilized.for contain-ment liner prefabrication has commenced.
This pad removal is necessary to begin ekcavation for the final section of Emergency Core Cooling Spray (ECCS) piping which will commence next month.
The assembly of'the main power transformers continues on schedule.
