Independent Inspection Effort a.
Construction Status (Units 1 and 2)
Nine sectional pours of the elevation 445 foot slab for Unit 1 been completed as of May 10, 1979. Formwork, reinforcing steel placement and installation of miscellaneous embedments continues in the Unit I reactor building area. Initial concrete placerants have been made in the sump areas of the Unit 2 reactor building. C.acrete operations in the personnel tunnel are nearing completion. Stainless steel tritiated and non-tritiated sumps are being installed in the Unit I reactor building area. Chicago Bridge and Iron Company (CBI) is welding ana radiographing sections of the carbon steel containment vessel plates on-site.
Construction of warehouse, office and shop buildings are continuing.
Fill cancrete pours have been conducted in the fuel building and waste management building foundation areas. The position of Supervisor, Welding QC Unit has been manned.
b.
Concrete Placement (Unit 1)
The inspector observed placement of Category I concrete pour Al-010 located at elevation 445 feet in the Unit I reactor building area.
Acceptance criteria examined by the inspector are specified in the following documents:
(1) Section 3.8 of the PSAR and TVA Topical Report TR-75-1A (2) TVA Specification G-2, " Plain and Reinforced Concrete" (3) Quality Control Instructions C-2'11 through C-214 (4) Drawing 4RE0417-5R-1, R5, Walls and Slabs (5) Drawing 4RE0418-5R-1, R-3, Reinforcement (6) Specification N8C-887, " Plain and Reinforced Concrete" Forms were tight and clean and preplacement inspection was indicated by the signed pour card. Areas inspected included delivery, conveying, placement, consolidation, testing and curing of concrete. The following records were reviewed by the inspector for pour Al-010:
(1) Concrete Pour Card (2) Concrete Sample Data Input (3) Mixing Plant Report (4) Concrete Curing Report Concrete operations were continuously monitored by Civil QC perscnnel.
Concrete placement, testing and inspection were conducted in accordance with applicable procedures.

Containment Vessel Welding (Unit 1)
c.
The inspector observed in process welding of the carbon steel contain-ment vessel plates.
Chicago Bridge and Iron Company (CBI) is the contractor responsible for far :ication of the spherical steel contain-ment vessel.
Welding was coaducted in accordance with WPS EH-14 (twia) for the basic weld and WPS 7018 for fit-up welds by qualified welding personnel. The contractor is using the automatic EH-14 weld process with a tilting platform to properly orient the spherical weld geometry.

The inspector reviewed repair records for the three repairs conducted to date on flaws detected during radiographic examination of completed plate welds. The repairs were conducted in accordance with approved repair procedare GR10X and documented in accordance with the CBI QA Manual for AS!i Section III Products, Issue 8.
Certified Material Test Reports for weld filler material heat numbers 432E3951, 422E5861 and 421E3481 were examined for compliance to Part C of Section II of the ASME Code.
No items of noncompliance or deviations were identified.
