the resident inspector of construction activities relating to:
storage and protection of plant equipment, training of mi llwrights in use of optical instruments, Unit 1 control room panel anchoring weldments, Unit 2 containment dome segment fabrication welds, and Unit 3 containment base mat reinforcing steel and safety injection system piping welds.
The inspection involved 42 inspector hours on-site by one NRC inspector.
Results:
Of the six areas inspected, one item of noncompliance was identified in the area of storage and protection of plant equipment (failure to properly store and identify components
- paragraph 2).

Stora e, Handlin and Protection of Safet Related Com onents The following Unit 1 components were selected by the inspector to evaluate the handling, storage and protection of components prior to, during, and after installation:
Safety Injection System Tanks Shutdown Cooling Heat Exchangers High Pressure Safety Injection Pumps Primary Charging Pumps Auxiliary Feedwater Pumps
These items were found to be adequately covered or coated with protective coatings.
None showed any evidence of improper handling and all items were properly supported and aligned.
No pipe or other openings were found uncovered.
Bechtel utilizes a computerized program to track and document maintenance and protection activities on permanent plant materials and equipment.
The requirements for utilizing the program are provided in WP/P-gCI No. 28.0, Maintenance of Materials and Equipment.
The records for this maintenance program pertaining to the above equipment were examined.
The inspector found that maintenance and surveillance actions were specified at frequent intervals and found no discrepancies in the carrying out and documenting of these activities.
The inspector did identify equipment protection and housekeeping problems in both auxiliary feedwater pump rooms in the main steam support structure (MSSS).
In the room housing the motor-driven P UlllP:
A 3-inch, schedule 80 stainless steel pipe spool (No. 1AF-035-S001)
"'was stored on the floor rather than placed on dunnage.
A 6-inch carbon steel check valve (no identification tag)
was stored on the floor rather than on dunnage.
A 6-inch motor operated, stainless steel valve (no identification tag)
was lying in a horizontal position on cribbing back in one corner of the room with no protective cover.,
=The exposed valve stem was covered with dirt.
In the adjacent room housing the turbine driven pump:
The motor operated, steam throttle valve on the turbine inlet was uncovered and water (possibly from overhead concrete curing activities)
was standing in the annular depression around the packing gland.
Seven stainless steel and four carbon steel pipe spools, all 6-inch diameter, were heaped on the floor and only some were partly stored on cribbing.
Some structural steel parts, possibly pipe hanger parts, were intermingled in the pile.
Two 6-inch stainless steel motor operated valves were lying on the floor with no supporting cribbing or covering, and neither valve had.any apparent identification.
One manually operated 6-inch valve also untagged and uncovered was lying on the floor beside the pum i1 o
-3-The room was generally dirty.
The above storage conditions for the items were contrary to the standards specified in Bechtel Procedure WP/P-gCI No. 202.0, Piping Systems Installation, and were therefore in noncompliance with the
.requirements of the approved quality assurance program.

0 tical Toolin Trainin Class for Craftsmen The inspector monitored a formal training program entitled "Optical Tooling" that was conducted after normal working hours by Bechtel for journeyman millwrights, surveyors, and quality control engineers.
It consisted of eight classroom sessions covering the fundamentals of optics, the features and functions of the instruments used (levels, transits, optical micrometers),
and techniques utilized in the use of the instruments.
This was followed by four classroom sessions of actual
"hands-on" practice with the optical instruments.
There were 27 individuals that attended the program.
The instructor was a Bechtel site staff engineer who has 26 years experience in optical tooling, electronic instrumentation, quality control, and training with a major aerospace firm and a prominent manufacturer of optical surveying instruments.
The sessions were well organized and professionally conducted.

Unit 1 Control Room Panels Anchora e
The inspector examined the fillet welds which fasten control room panels B01 through B07.to the floor embed plates.
The welds were specified as to size, length and location on the Comsip Customline Company drawings as follows:

The welding requirements were AWS Dl.l.
No items of noncompliance or deviations were identifie Unit 2 Containment Dome Se ments Five completed prefabricated, 30-degree triangular shaped segments for the Unit 2 containment dome were examined by the inspector.
(Twelve segments make up the complete dome liner structure).
These five were marked SEg-l, -2, -6, -ll, and -12 and were stored at the large component outdoor storage area.
Seam welds joining the subassembly plates displayed good workmanship.
Numerous welds which attach the stiffener members were examined and high quality work-manship was also apparent on these welds.
In several places, the curved edges which will be seam-welded to form the dome structure were mis-shapen in some locations.
This condition was discussed with the Bechtel Resident Engineer who stated that he had examined the segments previously and had noted the distorted edge curvatures.
He stated that he planned to resolve this situation with Unit 2 construction supervision, This matter will be pursued further by the inspector.

Unit 3 Containment Basemat Installation of a portion of the upper four layers of No.
18 deformed reinforcing bar in the basemat structure was observed by the inspector.
Construction aids to support the bars at the proper elevation appeared to be adequate and the bar was being appropriately tied in position to prevent lateral movement.
No departures were observed from the governing specification, 13-CN-375, Placing of Reinforcing Steel, or the applicable drawings, 13-C-ZCS-103,
-104 and -105 Containment Base Mat Reinforcing - Top Layers, Plan, Sections and Details.
No items of noncompliance or deviations were identified.
Unit 3 Safet Injection S stem Pi in One completed weld in each train of this supply piping for the low pressure safety injection and containment spray pumps at the 40-foot elevation of the auxiliary building was examined by the inspector.
In train A, the weld was H30 joining Spools 017 and 018 in line SI-A-241-GCBC-18, shown on dwg. 13-P-SIF-201.
In train B, the weld was ll16 joining spools 013 and 014 in line SI-B-194-GCBC-18, shown on dwg. 13-P-SIF-202 'oth welds exhibited high quality work-manship.
The qualifications of the welders who performed the work were checked and found to be valid for the procedure specified on the WR-5 forms.
Both MR-5 forms were properly completed, and the filler metal issue records were in order.
No items of noncompliance or deviations were identifie v
-5-8.
Plant Tours The inspector toured the construction site several times each week during the inspection report period.
Particular attention was given to work in progress, presence of quality control inspectors and supervision at the work locations, general housekeeping conditions, and overall care and preservation of equipment.
No items of noncom-pliance or deviations were identified during the plant tours.
