Applicant Action on Previous Inspection Findings (Closed) Unresolved Item (50-556/79-02; 50-557/79-02).
Site Receiving Inspection.
The unresolved item pertaining to receiving records, identified in the NRC Report No. 79-02, was reviewed during this inspection.
Procedure FPPM 3.3, " Site Receipt Inspection," has subsequently been revised to include procedural requirements for the attachment of final source surveillance waivers to the " Quality Control Release for Shipment" (QCRS) forms and for the com-pletion of the " Pre-Established Records Checklist" (PRC) forms.
The procedure now states thac, "if equipment / material arrives at the site without PS0 procure-ment QA representative signature, a waiver must be attached and a receipt inspection must be performed." The procedure also requires that upon notifi-cation of shipment arrival, the PRC be checked to verify that it is properly marked to indicate the states or the attached documents.
The procedure further states that " items received short of the requirement documentation or with inadequate documentation shall be placed on hold."
Based on the revisions to the procedure, this item is considered resolved.

(Closed) Unresolved Item (50-556/79-02; 50-557/79-02):
Concrete Mix Design.
The unresolved item pertaining to concrete mix design, identified in the NRC Report No. 79-02, was reviewed during this inspection.
The contract speci-fication with U. S. Testing has been revised by Description of Change Document (DCD) No. 187. TheDCQstatesthat, "the acceptance criteria of the resulting trjal mixes shall be - 0.5 percent of the maximum allowable air content and - 0.5 inches of the maximum allowable slump permitted by the specification." This revision to the specification conforms with American Concrete Institute Building Code Requirements for reinforced concrete.
Based on this revision, this item is considered resolved.
3.
Concrete Mix Design A review was conducted of the Mix Design Test Information for concrete Class C-2.
The following documents for this 4000 pound per square inch mix were specifically reviewed:
Concrete Trial-Mix Proportioning by ACI 211.1-74 Report a.
b.
Slump, Air, Unit Weight and Seven Day Compressive Strength Test Results Report The compressive strength results indicated that the required 4000 pound per square inch strength at twenty-eight days was being obtained in seven days.
This mix was authorized for use in the foundation excavation seal slab.
The IE inspecEo'r also witnessed in proc 33 laboratory mix design trial batching with associated testing and test cylinder manufacturing for the purpose of establishing the required strength versus water-cement ratio curve.
No deviations were identified.
4.
Concrete Placement The IE inspector witnessed the placement of concrete for the Reactor Building base mat seal slab for Unit 1 on two separate days.
Slump, air content, temperature and unit weight determinations were also observed.
Observed activities were found to be in conformance with J. A. Jones Construction Company Inspection Procedure No. 1, Revision 0, " Final Excavation and Placement of Seal Coat Concretc," and with PS0 FPPM 3.14, Revision 1, " Concrete Quality Control."
No deviations were identified.

Foundation Excavation and Mapping Excavation for the Unit 2 foundatica and mapping activities prior to seal slab placement in the Unit 1 Reactor Building area were observed.
The IE inspector also witnessed extensometer readings being taken for the area of the Reactor Building.
The Extensometer Monitoring Report was also reviewed.
This instrument measures the amount of foundation " rebound" which results from the removal of the overburden soils. The documentation of the foundation mapping was discussed with the field geologists performing the work.
All activities observed and reviewed were found to conform with Procedure FPPM 4.15, Rcvision 1, " Geologic Mapping," and with Black & Veatch, " Excavation Mapping, Inspection, and Monitoring Procedures," Revision 2.
No deviations were identified.
6.
Quality Assurance Audits The IE inspector reviewed records of QA audits performed on site in order to ascertain whether the audits were performed as prescribed in Procedure QFPM 11.01, " Site Quality Assurance Audit Program." Records of the following audits were reveiwed:
Audit Report No. CS-79-05, Audit of Anchor Concrete Company Quality a.
Assurance Program, performed April 24-27, 1979 b.
Audit Report No. CS-79-06, Audit of U. S. Testing Company Quality Assurance Program, performed May 22-24, 1979 The audits were performed and documented in accordance with the require-ments of Procedure QFPM 11.01.
No deviations were identified.
