New unresolved items identified during this inspection are discussed in paragraph 5.

5..

Independent Inspection The inspector examined ongoing work activities in Units 1 and 2, the i-soils and concrete testing laboratory, procedures for foundations and structural concrete, canpleted concrete structures and observed founda-tion grouting of fuel oil day tank 1B in the Unit 1 diesel generator building.

Examination of the above disclosed the following inspector identified items, a.

Concrete Honecomb Identification.

Revisions made in 1979 to procedure M-2 provide for identifying and tracking concrete honeycomb through canpletion of repair on concrete pours made after the 1979 revisions.

Observations by the inspector indicated that l

licensee methods are not clear as to how honeycomb that occurrred in concrete pours made prior to 1979 revisions are identified and tracked through repair. The inspector observed several honeycomb areas in pour numbers 2W72 and 2W74 made in August 25, 1977 and September 12, 1977 in the Unit 2 reactor shell wall which have not yet been identified or repaired. This was identified to the licensee as Unresolved Item 414/80-33-01, " Identification of Concrete Honeycomb."

persons discovering a nonconforming item to issue a nonconfoming item report as soon as possible. On October 30, 1980 the inspector observed through going cracks in the auxiliary building between column lines 60-61 along the exterior AA line wall from elevation 594 to 611 and adjacent roof area.

Investigations indicated that responsible engineers had known about the cracks but had failed to issue a nonconfoming item report. The licensee issued nonconfoming item report number 9975 on October 31, 1980.

Failure to issue a nonconfoming item report on cracking in the auxiliary building concrete was identified to the licensee as Infraction Item 414/80-33-02, " Reporting of Cracks in Auxiliary Building Concrete."

No deviations were identified.
