- denotes those present at the exit intervie The inspector also interviewed other licensee and contractor em-ployees during the inspectio . Plant Tour The inspector made a tour of the construction site to observe work activities in progress. The inspector examined work items for any obvious defects or noncompliance with regulatory requirements and ,
for evidence of quality control of the work. Specific activities observed by the inspector included installation of reinforcing steel for the containment foundation; and storage of steam genera-tors, reactor pressure vessel and reactor internal No items of noncompliance were identifie .

3 Observation of Concrete Placement and Preplacement Activities The inspector observed placement preparation and concrete place-ment of block No. LSK-104 as well as inspection and concrete tests performed in connection with this work. These activities were inspected for conformance to the following:
-- Forked River Nuclear Station, Unit 1, PSAR Section V and Appendix SD
-- B&R Specification 2700-206, Rev. 6, " Substructure"
-- B&R Specification '10-202, Rev. 8, " Production and Delivery of Concrete"
-- GPU Specification 202-003, Rev. 3, " Specification for Perform-ance of Owners Site Civil Testing"
-- GPU QA Procedure FR-1-10-04, Rev. O, " Site QA/QC Surveillance Procedure"
-- M-K Construction Procedure CP-04-FR, Rev. 3, " Construction of Containment Building Mat" Performance of the following activities was observed: Placement Preparation: Installation of forms, reinforcing steel, thermocouple well embedments, construction joints and waterstops; QC and surveillance inspection of placement preparation and sign-off of Concrete Placement Checklist; and briefing of concrete crews and QC personnel on placement pla Delivery and Placement: Proper mix specified and controlled mixing and delivery; adequate crew equipment, placement and consolidation; adequate inspection during delivery and place-ment; and required testing of delivered concrete and pre-paration of cylinders for future compression tests during placement of approximately 20% of this placemen Batch Plant Operation: Storage and inspection of aggregate and cement; and batch plant operation and record No items of noncompliance were identifie _ _ _ _ _ _ _ _ _ _ _

4. Thermocouple Calibration B&R specification 206 requires that thermocouples be installed in the containment foundation and that they be calibrated prior to insta11 tion. The inspection examined the calibration checklists for Digital Thermometer MK 137 and Thermocouples fiark 137A, through 137G. The checklists showed that the thermocouples met the specified requirements for accuracy within the required range. However, the checklists had been stamped UNCONTROLLED and licensee representatives on site could not provide the reason for this stamp. (363/78-11-01)
This item is unresolve . Anonymous Letter Concernino Placina of Rebar On August 23, 1978, the licensee reported that M-K, the construction contractor had received an anonymous letter from an ironworker stating that the rebar was not tied at every intersection and that 16 gauge tie wire was used. The licensee stated that this informa-tion was correct and conformed to the requirements of B&R specifi-cation 2700-20 The inspector examined specification 206. Appendix A, section 5. of this specification states, in part, " Placing of reinforcing steel shall be in accordance with CRSI Recommended Practice for Placing Reinforcing Bars...". Section 10 of CRSI (Concrete Rein-forcing Steel Institute). Recommended Practices for Placing Reinforcing Bars states, in part, " Wire used for tying reinforcing bars is usually No. 16 gauge black, soft-annealed wire," and
" Tying adds nothing to the strength of the finished structure. In most cases, every 4th and 5th intersection is all that is necessary."
During inspection of work activity during and prior to placement of concrete for block No. LSK-104 (Paragraph 3 above) the inspector observed that the rebar maintained its position during preplacement activities (form work, embedments, cleanup, etc.) and during place-ment and vibration of the concret The inspector had no further questions concerning this matter.

6. Review of Quality Assurance Implementing Procedures An inspection was made to determine whether quality assurance plans, appropriate and adequate instructions and procedures have been established for the fabrication and installation of the primary containment liner; and whether these QA plans, procedures and in-structions conform to the facility QA program as described in Appendix SD of the PSA The following documents were reviewed: Schneider Inc. Quality Assurance Manual C53300
' Schneider Inc. Magnetic Particle Inspection MT-533-1 Schneider Inc. Radiography Inspection RT-533-1 Schneider Inc. Dye Penetrant PT-533-1 Engineering Specification 2700-205 No items of noncomplaince were identifie . Unresolved Items Unresolved items are matters about which more information is re-quired in order to ascertain whether they are acceptable items or items of noncompliance. An unresolved item disclosed during this inspection is discussed in paragraphs . Exit Interview At the conclusion of the inspection on August 30, 1978, a meeting was held at the Forked River site with representatives of the licensee and contractor organization. The inspector summarized the results of the inspection as described in the report.
