5.
Independent Inspection Effort The senior resident inspector made 6 surveillance tours during which the status of project work was noted, and construction activities were inspected on nuclear safety-related structures, systems and facilities. The inspection was concentrated on Plant A power block structures, but included w
outlying structures such as the Plant A essential service water pump
=
stations, earthfill for the A-1 and A-2 spray ponds, nd valve stations and

Open Items Control: Newly issued Nonconformance Reports (NCRs), significant Quality Control Inspection Reports (QCIRs) and QA Unit audit findings were reviewed for pertinence to the inspection program and for adequacy of corrective actions.
Review of QCIRs and NCRs did not disclcse any violations or unresolved items.
The inspector toured the welder training and welder qualification areas to observe welder training and qualifications in progress. Observations of equisnent, facilities, and training aids were made in the welder training shop, and qualification area. The welder qualificatioa program was inspected for canpliance to procedural and ASME Boiler and Pressure Vessel Code Section IX requirements.
The following performance qualification tests were observed in progress:
Performance Qualification Test Welder's Identity SM-4-BH (Vertical)
4317 SM-4-BH (Vertical)
4315 SM-5-B-3H (6G)
1179 91-5-B-3H 1055 SM-4-B-H (Horizontal)
1180 S!1-4-B-H (Horizontal)
4319 Observations made by the inspector of the above tests included:
Base material, electrode type and size, weld position, electrical characte-ristics, polarity, preheat and interpass temperature.
In addition, guided bend test for performance qualification test SM-4-B-H, welder 4319, was observed in progress and was performed in accordance with the requirements of ASME,Section IX, paragraph QW-302.1.
In the areas inspected, no violations or deviations were identified.

By next to last paragraphs of the enclosure to TVA letter dated June 22, 1981, on this matter, the licensee committed to issue a memorandum by June 30, 1981, detailing corrective provisions to be incorporated into TVA's Engineering procedures to clarify design engineering responsibilities in implementing ANSI N45.2.5 and where required, to impose verification of joint fit up on construction drawings, in construction specifications, or in procurement specifications.
Licensee has not completed all procedural changes required.

Lakes, Dams, and Canals--Review of Work and Work Activities--Earth Fill For Plant A Spray Ponds The inspector made random inspections of eerth placement, compaction and compaction testing on the earth work between A-1 and A-2 essential service water spray ponds. Compaction testing in the field was inspected. Whenever the result was unacceptable, the sampled area was reworked and retested until adequate compaction was obtained.
Placement and compaction of earth fill for the peripheral dikes around the spray ponds is controlled by Specification N6C-875 Earth and Rock Foundations and Fills. By observation of placement and testing operations, the inspector verified compliance with Specification N6C-875 and with quality control procedure QCI-102, Foundation and Fill, Earthfill Control Testing.
In the areas inspected, no violations or deviations were identified.

buildings, auxiliary buildings, control buildings, essential service water pump houses, valve stations and electrical conduit vaults.
Specific placements inspected included:
A2A-51, 53, 65 188 Cubic Yards AIR-11A 28 Cubic Yards
-
AIA-10H 55 Cubic Yards AIKESWPS-104, 105 230 Cubic Yards AIKESW/V-18 116 Cubic Yards A2C-9, 9 40 Cubic Yards A0W-148, 149, 150 284 Cubic Yards Forms and rebar placement in preparation for placements in other areas were also inspected.
During inspection of activities for structural concrete in these areas, conformance with the requirements of C. F. Braun Specification 300-0,
,
Revision 8, " Concrete", TVA Construction Specification G-2, QCI C-201, Revision 4, and CEP 9.02, Revision 5, was verified by the inspector.
In the areas inspected, no violations or deviations were identified.
9.
Safety-Related Piping (Welding) Observations of Work and Work Activities The inspector observed welding of safety-related piping in A-1 plant, Fuel Pool Clean Up System (FPCU) and Residual Heat Removal System (RHR) outside of containment.
Verification of welding process to detailed weld procedure specification (WPS), detailed drawings and applicable code and requirements was made. The applicable code for piping inspected is the ASME Boiler and Pressure Vessel Code,Section III, Subsection NC and ND.1974 Edition, including addenda J
through S74.
The inspector verified: base material, welding filler material, and shielding gases were of the specified type and grade; fit-up weld joint geometry, including pipe wall thickness was as specified and met the gap and alignment limits required by the ASME code.
The welders perforning the welds were identified on applicable process control sheets and possessed current qualifications for process, position and thickness of weld.
The following welding characteristics were verified in progress.
For welds identified AIARH009005, AIFFC2210R05, and AIFFC2050R06; in compliance with weld procedure specification GTMS11-0-3B, Revision 8, anperage polarity, travel speed, interpass cleaning, electrode size and type, shielding gas flow rate, preheat and interpass temperature, and welding position.
In addition, the inspector performed visual inspection of in process and completed welds, observed magnetic particle (MT) examination of weld number AIFFC2050R06 and reviewed radiographs (RT) for weld numbers AIARH001, AIARH0004, AI ARH0009A, and AIARH003R1. Nondestructive examination
