Licensee Action on Previous Inspection Findings (Closed) Noncompliance (518/79-22-02, 519/79-22-02, 520/79-22-02 and 521/79-22-02:
Spray Pond Support Fill Testing.
Three point compaction tests were not performed on the spray pond support fill at least once for each 50 routine tests on each soil type being used as specified in specifi-p cation G-9.
The inspector examined the licensees' response dated October 26,
1979, and implementation of corrective action.
Procedure C-102 has been revised to clarify three point compaction testing; three point compaction tests have been made for earthfill operations during July-October, 1979 and July-September 1978. This item is closed.

Containment (Structural Concrete I.) Review of Quality Records, Unit 2B The inspector examined quality records for pour number B2R-1C8D on the unit 2B basemat. Acceptance criteria examined by the inspector were:
a.
PSAR, Section 3.8 b.
TVA Specification G-2, Plain and Reinforced Concrete c.
C. F. Braun Specification, TVA STRIDE d.
Procedures QCI-C-201 to 218, 401, 402; CEP 9.02, 12.01, 15.01 and 17.01 Examination of quality records disclosed the following noncompliance.
Criterion XVII of Appendix B to 10 CFR 50 which is implemented by Section
,
17.1A.17 of the PSAR states, " Sufficient records shall be maintained to furnish evidence of activities affecting quality." Test cylinder data sheets show that the water content varied twenty to twenty-five percent above the amount specified in the design mix on test cylinder numbers 10664, 10666, 10667, 10669 and 10670. Yet, slump and strength data were
.,
for the most part within design requirements and showed no signification variation from results where water contents were at the specified water content.
In fact, in some cases slump results were lower and strength results were considerably higher than batches where the recorded water content was less than specified. The contrasting water contents shown by the records are not compatible with test results. This item was identified to the licensee as Deficiency Number 521/79-29-1, Batch Plant Water Control.
