STATUS SUHMARY During the March 1980 report period, performance against the project summary target schedule has shown an overall improvement.
Manpower levels fell below those originally projected.
Overall
~
prod'ctivity levels. remain above those projected.
Several vendors u
.have forecast slippages in future equipment deliveries, which could impact the construction schedule.
Additional corrective action programs are under development.
Improvement in recently identified critical paths will be realized as the goals of these programs are accomplished.

1 Monthly Report CONTAINMENT The last of the prefabricated upper fuel pool liners was set in place during this report period.
Alignment of upper fuel pool liners ~is completed and welding is under way.
Reinforcing steel placement for all walls up to the 828 refuelling deck elevation is in progress.
Removal of shoring for the 803 slab has started and should be complete by the first week of April.
Electrical penetration, lighting, and communication work have commenced in L
the drywell.
As shoring is removed, structural steel platform placement will begin thus allowing the critical cable tray erection
(,;
to get under way.
During this report p *iod the form work was removed from the walls of the main steam tunnel and 270 degree equipment room.
Surface finish coatings were then applied prior to the main steam guard and process piping being rigged into this area.
Shoring was installed and the concrete roof was placed for the steam tunnel during March.
Reactor recirculation piping nears compeletion.
Templates are being-fabricated for the discharge closure pipe spools which will be machined off site.
Core plate installation is complete inside the reactor pressure vessel.
Han-gers are being installed for the control rod drive: system under the vessel.

,_ FUEL BUILDING The construction sequence on the final exterior concrete
.g
. walls is nearing completion with the concrete placement scheduled for mid April.
The slab at elevation 755 feet has been delayed due to recent electrical design revisions and is also scheduled for placement in mid April.
Large and small bore piping installation as well as electrical hangers and cable tray continued at the scheduled. pace on elevation 712 feet.
Piping and electrical erection-have been curtailed on elevation 737 feet due to the shor-ing supports for the elevation 755 foot slab;.however, these activi-ties are still projected to be accomplished ahead.of schedule.
AUXILIARY BUILDING
(
.{
Shoring and form work for the elevation 750 feet mezzanine slab are installed and the installation of reinforcing steel is under way.
Concrete placement and the subsequent removal of formwork and shoring will allow pipe and electrical erection to accelerate in this area.
Gas boundary steel erection continues at elevation 737 and has started at elevation 781.
The installation of large bore piping and seismic hangers and cable tray ~ continues'on the first three elevations of this building. ' Installation of the non-segregated bus at elevation 737 nears completion.
This will allow an intensified effort toward erection of cable tray and tray risers.
Rails for the 4160-volt switchgear have been installed on elevation 762 feet.
Finished floor concrete placement in this area is complete.
Rail installation has commenced at elevation 781 feet.
~
TURBINE BUILDING On March 1 and March 8 the two moisture separator reheaters were set into position at elevation 759 feet.
These rigging opera-
~
tions constituted the last major lifts (over 100 tons) on the project.
Civil work continues on the wall pours in the heater bay.
With the moisture separator reheaters in place, the civil effort to close the construction openings is under way.
Roof drain work is complete and the roofing subcontractor will runobilize next month to complete the roof for this building.
Condenser-tubing installation started this month on a two-crew singleishift basis, and is ahead of schedule.
. piping is being erected in the top of the condenser to support-the C
placement of the lower turbine exhaust hoods.
Turbine exhaust hood sole plates and the turbine standard base plates were final aligned and leveled this month.
Setting of the high voltage bushing box'under the stator was accomplished including complete weldout.
The installation of large and small bore piping, cable tray and conduit continues at all elevations of this building.
A highlight of these activities is the preliminary alignment and fitup of main-steam cross around piping now in progress at the south end of the condenser.
Instrumentation work continues with eight additional panels set this month.
Wire and cable pulling has commenced in this building.

CONTROL BUILDING G<
The interior walls on the HVAC slab at elevation 825 feet "were completed allowing the application of waterproof membrane beneath the equipment foundations.
Equipment foundation construction is under way and is expected to be completed next month.

< pm of.the overhead structural steel is complete.for the Unit 1 area, thus allowing 1NAC duct and cable tray erection to begin in support of the Power Generation Control Complex (PGCC) set this summer.
Fireproofing of all overhead structural steel in this area will be completed during' April.
A temporary of fice-has been erected at this elevation to house all of the appropriate personnel to
. coordinate control ~ room construction and startup. activities.
Large and small bore piping erection continued throughout the' building and remained ahead of schedule.
Cable tray hangers and tray installation continues at an acceptable pace except in the cable spreading room at elevation 781 feet.
In this area,a significantschedulerecoveryhasbeen'accomplisheg, utilizing _the corrective action program discussed in last month's report of
" Problem Areas."
Battery racks and temporary battery ro'om exhaust fans were-installed this month.
The laboratory air handling filter units on elevation 751 feet, building exhaust fans at elevation 719 feet, and the hydrogen recombiners at elevation 702 feet were also l

- installed during March.
Conduit installation is now under C,"'
way on the lower four elevations of this building.
DIESEL GENERATOR BUILDING Civil work continues at a reduced level in this non-critical building.
The remova'l of the temporary roof cover for permanent roof installation, foundation concrete placement, and block wall
-installation were the only civil activities this month.
The align-ment of drywell purge units was completed and the standby gas treatment units were roughset.
The reported installation of both piping and electrical quantities was light this month as manpower was being concentrated L, -
in other more critical buildings.
RADWASTE BUILDING Major civil activities have been on roof and labrinth slabs in support of block wall erection and equipment sets.
Work continues on elevator walls as required by the Elevator Erection schedule for May, i
Foundation pads for motor control centers M and N are complete and equipment was set during March.
Foundations for the air handling units at elevation 762 feet were also completed during this report period.
Other equipment sets this month include a flash tank and a drain tank on elevation 702 feet, four instrument panels on elevation 762 feet, and a subcooler and condenser on elevation 762 feet.
O
=
Erection of.large and small bore piping continues at all L,
elevations.of this building.
The installation of tray hangers, cable tray, conduit installation, and wire and cable pulls continue at an acceptable pace and remain non-critical.
SCREENHOUSE Construction of the mezzanine slab over the UdiE'1 fire protec-tion pumps and day tank was completed this month.
The 15-ton travel-ing crane was energized, tested, and released for construction use.
HVAC duct work installation commenced this month and the erection of large and small bore piping, cable tray and conduit, and equipment installation, and equipment aligning and grouting' remained ahead of schedule for this building.
YARD Excavation for the Emergency Core Cooling System (ECCS) piping commenced this month and will continue through the summer.
Excava-tion was also started for the microwave tower foundation this month.
The assembly of the main transformers continues on schedule with oil fill under way.
