Site Tour On October 7, 1980 the inspectors conducted a general facility tour, to observe completed and in-progress i7ork'for"deviations or noncompliance with PSAR commitments and regulatory requirements.
During the tour of the Unit 3 Auxiliary Building the inspectors noted-the following: kJPP/QCI No. 52.0, "Concrete Preplacement", Appendix I states in paragraph C, "Verification instructions/responsibilities" Item No. 14,'lean-up, that the Civil QCE, "Verify that the area for concrete placement meets the cleanliness requirements of 13-CM-365, Sections 6. 1. 3-, 6.4.2, 6.6.2 and 10.3.
Specification No.
13-CM-365, "Installation specification for the forming, placing, finishing and curing of concrete" Section 10.3 states in part that, "Debris, mud, snow, and ice shall be removed from spaces to receive concrete and the reinforcement and other metal to be embedded shall be cleaned of all coating which might impair the bond.".
~ ~ ~ ~
~ ~ Contrary.to the above three pockets of defective concrete extending beyond the first layer of rebar were found to contain debris including cigarette butts, tape, wood, glass, paper and RODOFOAM material.
These rock pockets are located at two construction joints at the 68'levation, on the west face of a shaft wall on AF line between A7 and A8 lines.
Examination of the Construction Inspection Planning (CIP) for concrete preplacement for placements nos.
3A035, 3A036 and 3A038 (a floor slab) and for placement nos.
3A044 and 3A119 (the shaft wall) indicated that the FACE had sign-off Item No. 14, "Final Clean-up" (of the CIP's), for all the placements as satisfactory.
Upon notification of this condition the licensee immediately issued a nonconformance report to effect corrective action.
The acceptance of the two areas to receive concrete is considered an apparent item of noncompliance.
(50-530/80-16/01) Electrical Cable Installation Installation of the following Unit 1 Class 1E electrical cables was observed to ascertain compliance with Bechtel procedure WPP/gCI-254, "Electrical Cable Installation:" . Cable No.

Particular attributes examined included condition of cable trays, identification of trays and cable, condition of cable, communication between members of pulling crew, proper sealing of cable, ends, protection of cable, and proper tie down of cable.
Also, the pull cards for these cables were reviewed.
No items of noncompliance or deviations were identified.

Struciural Concrete a.
Observation of Hark and Hork Activities Concrete testing and ihe siie tesiing laboratory were examined for compliance with the pertinent ACI/ASTH, contract specifications and PSAR commitments.
The examination included observations of field testing activities, labora.ory housekeeping, equipment conditions, operaiion, calibration status, concrete. cylinder facilities, and cylinder marking and storage.
During the examination of the concrete testing laboratory manned by Champion, the inspector observed that the coarse and fine aggregate sieves appeared to have missed the annual check required by Champion's procedures manual.
Discussions with cognizant engineers determined that the sieves had actually been checked, but through an administrative error the wrong date had been typed on the recall sticker.
A review of the Champion report verified that the sieves had been checked as required.
The licensee took imediate action and corrected the stickers.
Based on the review of the report and visual examination of the sieves for obvious improper handling and damage, the inspector has no further questions on this matte )
b.
Review of ualit Records Records pertaining to concrete production and placement activities were examined for compliance with licensee procedures, specifications, and PSAR requirements.
The record included water, ice, aggregate tests, placement records, NCR's, concrete cylinder compression tests, certificate of conformance, and the qualification records of 10 OC inspectors.
Ho items of noncompliance or deviations were identified.
c.
OA Audits The inspector selected four gA audits performed by Bechtel on ETL and Champion activities for the current year.
The audits examined were Audit Hos. 80-ETL-H-7, 80-ETL-S-16, 80-CHA-S-8, and 80-CHA-S-Z9.
The audits appeared to be planned and carried out with the frequency and requirements of the licensee's gA program.
Ho items of noncompliance or deviations were identified.
6.
Stud lleldinq Completed Helson studs at the 83'levation of the Unit 3 Auxiliary Building were examined for compliance with the licensee's procedures, specifications, and AMS D1. 1 Code requirements.
The inspectors visually examined the studs to verify that the studs were properly bent, marked, and they had a full 360 degree weld.
Ho items of noncompliance or deviations were identified.
