Licensee Action on Previous Inspection Findings (0 pen) Unresolved Item (424/81-09-02 and 425/81-09-02) Training Requirements of Contractor Furnished Civil QC Inspectors. The inspector examined licen-see audit numbers TR01-81/62 and Q C01-81/76, and qualification records of ten civil QC inspectors supplied by licensee contractors. Examination of these records indicated that the contractor furnished civil QC inspector training and qualification requirements appear to be in accordance with licensee commitments and NRC requirements. However, this item remains open pending further examination by NRC of contractor supplied QC inspector qualification a

(0 pen) Unresolved item (424/82-03-01 and 425/82-03-01) Compaction Contro Specification and procedure instructions allow the selected proctor to be the compaction standard for seven sand cone tests made in one day provided the sand cone dry densities are within 1.5 pounds of each other and the color and texture of the soil material are the same. The specified method to a large degree is dependent on the judgement and experience of the technician doing the proctor selection. The dry densities of the sand cone tests could be the same and the color of the material could be the same; but if the texture or grain size of the material varied significantly (a diffi-cult variation to determine visually), the materials could have different compaction standards. Because difficulty in determining texture differences could result in the selection of the wrong proctor, the inspector requested the licensee to perform additional proctor tests on selected groups of sand cone tests (7 or more samples represented by a proctor) to verify that the judgement being used by soil technicians is adequate. This item remains open pending further review by NR Unresolved Items Unresolved items were not identified during this inspectio . Independent Inspection Effort The inspector examined the following: Soils and concrete laboratory and currentness of calibration of labor-atory equipmen Ongoing preparation for concrete placements in the Unit 1 power bloc Backfill operations in the powerblock DR CD 1942, Threaded Bolt Type Embeds Inspection of embedment plates with threaded anchor bolts disclosed that some anchor bolts did not have full thread engagement. This item was reported to NRC by telephone on April 23, 1982 as a potential 50.55(e)

item. Georgia Power is investigating the item and will submit an evalua-tion report to the NRC. This item is identified as Inspector Followup Item 424/425/82-09-01, Threaded Bolt Type Embed No violations or deviations were identifie . Containment (Structural Concrete II) - Observation of Work and Work Acti-vities (Unit 1)

The inspector observed partial placement of pour number 1-010-11 in the Unit 1 containment. Acceptance criteria examined by the inspector appear in the following documents: Specification X21P01, Forming, Placing, Finishing, and Curing Concret J

3 Procedure CD-T-02, Concrete Quality Control PSAR, Sections 3 and 17 Forms were tight and clea Rebar was properly installed and clea Examination of the batch plant indicated proper mixes were being delivered, materials were being controlled, and that accurate batch plant records were being generated. Samples for temperature, slump, air content, unit weight, and strength met frequency requirements. Concrete placement activities were continuously monitored by QC inspectors. Placement activities pertaining to delivery time, free fall, flow distance and consolidation conformed to procedure and specification requirement No violations or deviations were identifie . Site Preparation and Foundations - Observation of Work and Work Activities, Units 1 and 2 The inspector observed and discussed ongoing investigations of the Millet Fault which was identified in a news release by the United States Geological Survey (USGS) on February 26, 198 The USGS news release indicated the fault is located about 7 miles south of the Vogtle plant. Georgia Power has formed a task force which is presently gathering data to obtain a better definition of the fault by subsurface drilling, seismic profiling along the Savannah River, and a study of groundwater levels in wells surrounding the are No violations or deviations were identified.
