Low Level Radwaste Facility a.
Structural Concrete The inspector examined completed work on concrete storage modu'es 1, 2, 3 and 4 and two partially completed concrete modules which have been indefinitely deferred. Work on modules 1, 2, 3 and 4 is 98 percent complete. The inspector also examined the concrete testing laboratory, l

Exanination of completed work and records showed that structural concrete work met drawing, specification and procedure requirements.
No violations or deviations were identified.
b.
Foundations The inspector examined drawings, procedures and specifications contrciling foundation preparation and quality records documenting inspections and testing on completed work.
Drawings, specifications and procedures examined by the inspector are:
(1) Drawing 10E151-07, Foundation Investigation Grid-Low Level Radwaste Storage (2) Drawing 1GE156-01, Low Level Radwaste Storage Facility Trash and Resin Storage Structures

Examination of Earthfill Compaction Test Graph Calibration Records for Borrow Area A and LLRW Borrow Area disclosed a departure from procedure requirement.
Procedure QCI-C-1000 requires that in making the calibration of Earthfill Test Graphs, the following steps be performed:
(1) A sample for the test be taken in conjunction with the' sand-cone density test for the one point proctor.
(2) Plot the four moisture density points on the graph and draw a smooth curve through these points.
(3) Compare the shape and value of this curve with the shape and values fo the curve that identified the soil class in Instruction 3.1.C of the QCI. If the shapes and values of the curve differs initiate a QCIR and send a companion soil sample to S0ILS LAB per paragraph 11.2 of Specification G.9.
Records of the earthfill compaction test graph calibrations show that none oF the above procedure requirements were followed.
This was identified to the licensee as an unresolved item in that the license for amendment is still pending. The item was identified as Unresolved Item 50-259/81-31-01, 50-260/81-31-01 and 50-296/81-31-01, Compaction test graph calibration.
