521/79-22-01): Documentation of Inprocess Test Data on Concrete and Earthfill. Documentation of test data on concrete and earthfill placements did not appear to show that required sampling intervals were being met during inprocess testing.
Procedures and attached documentation have been revised to clarify records of sampling intervals. Examination of records on testing of concrete and soils showed that required sampling intervals are being met.
This item is closed.
b.
(0 pen) Noncompliance (518/79-22-02, b.P/79-22-02, 520/79-22-02 and 521/79-22-02):
Spray Pond Support Fill Testing. Three point com-paction tests were not performed on the spray pond support fill at least once for each 50 routine tests en each soil type being used as specified in specification 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; three point i690 235

6.
Containment (Structural Concrete I) - Observation of Works & Work Activities, Unit B-2 The inspector performed a follow on inspection of a concrete placement in the Unit B-2 basemat.
The inspector observed the partial placement of pour number B2B-IC8D; 5, 956 cubic yards of concrete were placed, using pumps and concrete buckets. Acceptance criteria examined by the inspector were:
a.
PSAR, Section 3.8 b.
TVA Specific. ion 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 Preplacement was indicated by the properly signed pour card.
Placement activities pertaining to delivery time, free fall, flow distance, layer thickness and consolidation conformed to specifications. Activities were continuously monitored by QC personnel.
