Exit Interview The inspection scope and findings were summarized on January 28, 1982 with those persons indicated in paragraph I above.
3.
Licensee Action on Previous Inspection Findings (Closed) Unresolved Item (395/81-19-01):
Post-tensioning Ram Calibration Records.
These records were unavailable for review during the previous inspection (81-19). The licensee obtained records for the calibration of the stressing rams after completion of the onsite stressing work from the post-tensioning system contractor, INRYCO, Inc.
The purpose of the post-work ram calibrations is to determine if the rams remained in calibration during the onsite stressing work. The inspector reviewed these records and verified that the rams had been calibrated as required by the project specification. This item is closed.
4.
Unresolved Items Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve violations or devia-tions. New unresolved items identified during this inspection are discussed in paragraph 6.

Site Preparation - Review of Quality Assurance Implementing Procedures The folicwing procedures and specifications were examined to determine if work activities and quality control and quality assurance functions were provided for as stipulated in NRC r4quirements, FSAR Sections 2.5.4 through 2.5.6, and the SER:
a.
GAI specification SP-211-4461-00, Excavation and Placement of Structural Fill b.
Procedure number FQCP 5.1.1, Structural Backfill and Earthwork c.
Procedure number FQCP 5.1.2, Surveillance and Control of Rock Basting d.
Procedure number FQCP 5.1.4, Earthwork Test Traceability e.
Drawing number E-401-021, Site Preparation Excavation Plan f.
Drawing numbers E-401-022 through E-401-025, Site Preparation
'
Excavation Sections No violations or deviations were identified.
6.
Site Preparation - Review of Quality Records The inspectors examined the following quality records relating to site preparation:
a.
Results of relative density tests performed on Zone III fill supporting the fuel oil storage tank b.
Verification of results of nuclear density tests by use of sand cone density tests for the period April 1976 through October 1977 c.
Nonconformance Notices, numbers 195C and 287C d.
Results of compaction tests performed on Zone II fill materials Acceptance criteria examined by the inspectors are those procedures listed in paragraph 5.
Review of the above records and discussions with QC personnel disclosed that backfill under and around safety related piping and ductbanks in the West Embankment area may not have been controlled as required by specification requirements.
Licensee engineers and QC personnel stated that records may be available to document that the fill materials under and around the safety related piping and ductbanks was placed in accordance with specification requirements. The lack of quality records to document the fill placement for safety related piping and ductbanks was identified to the licensee as.
Unresolved Item 82-14-01 " Piping and Ductbank Fill Placement Records."

Drawing number E401-026, Foundation Mat Plan and Outline of Building Foundations Discussions with responsible engineers and examination of the above listed documents indicated adequate instructions, plans and procedures were established for control of foundation construction.
No deviations or violations were identified.
8.
Foundations, Review of Quality Records Records examined by th. inspectors were those for the foundations of the reactor, control, intermediate, fuel handling, auxiliary and diesel generator buildings, and the condensate and diesel generator fuel oil storage tanks. The reactor, control ano auxiliary buildings are founded on rock. The diesel generator, fuel handlit g, and intermediate buildings are founded on caissons extending into rock.
The diesel generator and condensate storage tanks are founded on crushed rock (Zone III fill).
Detailed records on inspection and installation of caissons FHB-22, FHB-26, FHB-27 and IB-35 were examined by the inspectors.
Acceptance criteria examined by the inspectors are those applicable procedures listed in paragraphs 5 and 7.
Records showed that the caissons were inspected and installed in accordance with acceptance criteria.
No deviations or violations were identifie,.
