Licensee Action on Previous Inspection Findings a.
(Closed) Unresolved Item (566/78-10-01 and 567/78-10-01): Frequency of sampling for test cylinders, air content, temperature and slump.
The inspector reviewed Revision 5 to QCI 2 08 which states sampling shall be at the 100 cubic yard interval specified in the PSAR. The inspector reviewed batch plant inspection records and records of tests performed on plastic concrete (slump, air content, temperature, and strength) for the period January 4,1979 through May 15, 1979, and decermined that Category I concrete was sampled at the frequency specified in the PSAR. This item is closed.
b.
(Closed) Unresolved Item (566/78-10-02 and 567/78-10-02):
Pumped Concrete. The inspector reviewed Revision 5 to QCI 208 v'ich requires a
pumped concrete to be sampled at the pump line discharge as specified ia ANSI standard N45.2.5-1974.hich is referenced in the PSAR.
No Category I concrete has been placed by pumping to date. This item is closed.

Control and Waste Management Buildings, Structural Excavation" Dewatering is being controlled by ditches and sumps. Fill concrete has been placed on bedrock in the Fuel Building and Emergency Sumps and geologic mapping has been completed in these areas. Final approval of foundations before placement of concrete is through a foundation inspection team made up of engineers and geologist from the site and engineering design.
No deviations or items of noncompliance were identified.
