Functional or Program Areas Inspected 1.
Plant Tours One or more plant areas were toured several times each week during the reporting period to observe general construction practices; area cleanliness and storage condition of equipment, piping, and cable.
Three tours were made on back shifts of work.
No items of noncompliance or deviations were identified.
2.
Electrical Component Installation and Other Related Electrical Activities a.
The assembly of electrical penetration 2ZNE281 was observed.
Assembly was performed in accordance with work procedures. The-2-

installed penetrations were protected from construction debris
and were charged with inert gas as required by procedure.
No items of noncompliance or deviations were identified.
b.
During a plant tour, it was observed that debris was present on safety related cables that had been installed in their cable trays. This condition was reported to the licensee.
The debris was immediately removed from the cable trays.
No items of noncompliance or deviations were identified.
c.
The welding of electrical cabinets to the floor was observed.
One electrical switchgear/ motor controller cabinet in the north electrical penetration area and one in the south electrical penetration area was selected for inspection. The welding required by Drawing FS-E 300Z was performed. The welds met fillet size and length requirements.
No items of noncompliance or deviations were observed.
2.
Concrete Placement During the reporting period, three concrete placements were observed.
a.
Placement 2C281WO8 (Exterior Dome Lift),
b.
Placement 2C251W28 (West Side Secondary Shield Wall).
c.
Placement 2C252S01 (South East Elevated Slab).
For each of the placements listed above, some or all of the following conditions were noted.
(1) The forms were secure, leak tight, and had been wetted prior to the placement.
(2) The preplacement inspection had been completed and was in order.
(3) Quality Control inspectors were assigned to each crew in addition to those assigned to perform periodic concrete testing.
(4) The concrete temperature was satisfactory and the area of the placement was heated to comply with cold weather
)
concreting requirements.
(5) Concrete testing was performed at the required frequencies.

.
(6) Adequate numbers of crews and personnel were assigned to make the placement.
(7) The placement was satisfactory.
(8) Curing was monitored and found to be satisfactory. The area of the concrete was protected from the weather.
No items of noncompliance or deviations were identified.
3.
Fabrication of Reactor Coolant Pressure Boundary and Safety Related Piping Systems a.
During the reporting period, the inspector observed work in-cluding handling, protection, inspection, and welding of reactor coolant pressure boundary and safety related piping systems.
(1) Reactor Coolant System Weld 2BB-01 F003 2BB-01 F004 (2) Borated Refueling Water Storage 2BN-01 FW42 2BN-01 FW46 (3) In Core Instrument Tube Welding Field welds 6 and 12 shown on Drawing D-1209E10.
(4) Accumulator Safety Injection Pipe 2EB-01 F019 (5) Containment Penetration Pipe Welds 2EJ-04-F001
'
2BB-08-F003 2BB-11-F003 2EC-02-F021 For each of these welds one or more of the following fabrica-tion activities was observed. Handling and protection of-4-

piping and partially completed welds was satisfactory. Purge
gas was correctly used. The joint fit-up dimensions were within procedural requirements and certified as qualified for the procedure specified to be used for welding the pipe joint.
No items of noncompliance or deviations were identified.
b.
Nondestructive Examination of Piping Welds (1) Liquid penetrant testing of reactor coolant pressure boundary weld, BB-01 F202 was observed. The surface of the weld was suitable for the examination. The liquid penetrant test techniques used by the inspectors were satisfactory.
(2) Visual examination of welds in the accumulator safety injection system was observed. The visual examination of six field welds was performed. The technique used by the inspector was satisfactory.
No items of noncompliance or deviations were identified.
4.
Structural Welding During the reporting period, the inspector observed welding and reviewed procedures associated with installation of the Auxiliary Access Hatch penetration. The work was performed by Chicagc Bridge and Iron Company. Welding and weld rod control was performed in accordance with procedures.
5.

On March 11, 1980, the inspector accompanied Region III inspectors H. Wescott and R. Jackson during an inspection performed at Union-5-
.
Electric Company's main office. On March 27, 1980 the inspector
.
assisted R. Burton during an investigation at the reactor site.
The investigation was initiated to determine if a 3/4" crack was present in any accumulator piping circumbential welds. No cracks were observed in any welds inspected, however, the investigation was not completed during this inspection.
Exit Meetings The resident inspector attended exit meetings conducted by RIII inspectors H. Wescott and R. Jackson on March 11, 1980, R. Landsman on March 27, 1980 and R. Burton on March 27, 1980.
The inspector met with licensee representatives (denoted under Persons Contacted) on March 6, 19, 20, and 28, 1980. The inspector summarized the scope and findings of the inspections performed.
