3.
Unresolved Items No unresolved items were identified.
4.
Independent Inspection Effort The inspector examined the following areas:
a.
Overall construction status b.
Soils and concrete lab c.
Concrete batch plant d.
Reinforcing steel laydown area and results of physical and chemical tests (Certified Mill Test Reports) performed on reinf orcing steel Training progran for Civil QC inspectors e.
f.
Storage area and preventative maintenance program for RHR heat exchangers and f uel pool heat exchansers l
g.
Impervious borrow explorations h.
Gradation records for coarse and fine aggregates and Vulcan Materials Corporation's Kingsport Quarry (quarry is supplying aggregates for the project).
Gradations of aggregates being produced do not meet TVA specifications. A QCIR has been written and the licensee is investigating causes of the problem.
No Category I concrete has been placed as of October 20, 1978.
No deviations or items of noncompliance were identified in the areas examined.
Site Preparation - Observation of Work and Work Activities, Units 1 and 2 The inspector observed work and results of wo.k activities for excavations of Units 1 and 2 powerhouse blocks.
Excavations were accomplished by drilling and blasting; dewatering is being controlled by ditches and sumps. Acceptance criteria examined by the inspector appear in Sections 2.4 and 2.5 of the PSAR and SER and responses to NRC
