2.
Plant Tour The inspector conducted a walk-through inspection of the construction site and observed completed work, and work in progress.
The areas observed for Unit I were containment building basemat, reactor pit liner, and auxiliary building concrete; in Unit 2, containment building basemat, foundations for the diesel generator and fuel storage buildings.
The inspector examined construction operations for compliance with regulatory requirements and licensee commitments.
No items of noncompliance were identifie.
Licensee Action on Previous Inspection Findings (Closed) Unresolved item (443/78-07-01 and 444/78-07-01): Lack of documentation of concrete temperatures during 24-hour period following the end of protection.
The inspector examined Revision 2 to Perini Quality Assurance Procedure QAP 10.5, which added the requirement to check concrete temperatures on the day following discontinuation of shelter heat.
He also reviewed Perini NCR 115, closed on September 18, 1978, and determined that concrete temperature records, where available, had been checked. Where records were not available, the Perini Lead QA Concrete Inspector had verified that temperature monitoring, during the time periods in question, had been accomplished.
(Closed) Unr.asolved iter (443/77-10-01 arid 444/77-08-01): Clarification of random sampling of car identified in specifications.
The inspector reviewed correspondence covering responsibnities of the Vendor Sur-veillance Representative and also verified Mill Test Reports on grade 60 reinforcing steel.
He observed that rebar conformed to ACI Standard 359-74, section CC-2300, Materials for Reinforcing Systems, as regards acceptance standards under ASTM A615. Additionally, records on tensile tests of cadweld splices indicated that no problem on strength of rebar existed.
The inspector observed, in correspondence from UE&C project manager, that the specification option to require additional random samples of rebar for confirmatory tests was an option only if warranted.
4.
Safety Related Components - Review of QA Procedures and Observation of Work (Units 1 and 2)
a.
The inspector reviewed procedures pertaining to the storage, handling, protection, and receipt and maintenance insnection of safety related components.
Particular attention was paid to documentation and certification requirements, inspection fre-quency and scope, and QA authority relative to the release of equipment for installation. The inspector also checked the procedural requirements regarding the load testing of construction lifting equipment used to handle safety related items.
The above areas were evaluatec against criteria established in the Seabrook Station PSAR, Chapters 3 and 17; ANSI N45.2.2-1972; and Regulatory Guide 1.3 The following documents were included in the review:
UE&C Quality Control Procedures QCP-7-1, Revision 3

--
FGCP No. 10, Revision 1
--
FGCP No. 16, Revision 2 UE&C Specification 9763-006-58-2 No items of noncompliance were identified.
b.
The inspector examined the storage condition of selected safety related components located at the Newington, New Hampshire storage facili ty.
He checked the adequacy of personnel access controls, warehouse temperature and humidity controls, dunnage, and material protection and segregation measures.
He verified that the selected items were properly stored, identified, and tagged with the appro-priate UE&C inspection status and that preventive maintenance inspections were being accomplished in accordance with the vendors' maintenance instructions.
The traceability of equipment to its material documentation and to its proper storage location was also spot-checked.
Receiving inspection reports for the selected components were reviewed, and accompanying records checked for completeness.
The certification and qualifications of one UE&C QC Level II storage and handling inspector were examined for conformance to ANSI N45.2.6 requirements.
The inspector also spot-checked the load test certification of two cranes involved in the handling of safety related components.
The above areas were evaluated against criteria established in the references and procedures listed in subparagraph a. above, and the applicable vendors' maintenance and storage recommendations.
Those safety related components, and their associated records, selected for inspection purposes, are listed below.

UE&C NCR 151 UE&C Receiving Inspection Report No. 695 Struther Wells Corp. Manufacturer's Data Report (Form N-1)
Struther Wells Corp. Certificate of Compliance No items of noncompliance were identified; however, one item remains unresolved as discussed below.
The inspector noted that routine storage activities for safety related components often involved the use of gray duct tape for attaching tags or blanking off openings.
Since many safety related components are coated with a gray primer or paint, the use of this tape on those components is in variance with the requirements of ANSI N45.2.2 and Regulatory Guide (RG) 1.38.
Also, the inspectc,.
found that the Letter c' Certification for the "Permacel" tape in question indicated compliance only with ANSI N45.2.2 and not with the requirements of RG 1.38, which differ somewhat from those of the ANSI Standard.
The licensee does, however, commit to RG 1.38 in Chapter 3 of his PSA Interviews with licensee personnel indicated that improperly colored tape could be replaced during ongoing maintenance activities.
Pending licensee action to review the commitment to the require-ments of RG 1.38 regarding tape, and to initiate a program of improperly colored tape replacement, this item is unresolved.
(443/78-15-01 and 444/78-15-01)
c.
The inspector examined the storage condition of four Westinghouse RHR pumps and motors (Storage Level C) and four Southwest Fabri-cating Accumulators (Storage Level D) located on the Seabrook site.
He checked attached preventive maintenance records and quality control release tags and interviewed the responsible UE&C material control engineer concerning storaca requirements at the Seabrook site.
Nitrogen inerting pressure indications for the accumulators were spot-checked.
No items of noncompliance were identified.
5.
Safe _ty Related Piping - Observation of Work - (Units 1 and 2)
The inspector observed the handling, placement, and pipe coating activities of the buried Service Water piping for spool Nos.1 CW-1801-3-153-24, 2-SW-1801-3-153-24, and 2-SW-1802-3-153-24.
He verified that the foregoing activities were being performed in accordance with UE&C Specification No. 9763-006-248-51, Revision 3.
A visual examination of the fabrication shop coating disclosed what appeared to be repair areas that do not meet the requirements of Specification No. 9763-006-248-2, Revision 2, paragraph 3.5.3.11.
The areas in question present a non-uniform surface to which a tar-like substant, has been applied.
The tar-like substance has approximately 1/8" deep cracks in it, with no evidence of the required asbestos felt or glass matting bonded to it.
This item is considered unresolved pending further evaluation of the condition by the licensee.
(443/78-15-02 and 444/78-15-02)
He also observed the magnetic particle testing of the Unit 1,24" diameter, nuclear class 3, service water pipe weld No. F0204, Isometric Drawing No. 1801-02. He verified that the test technicians were performing the test in accordance with procedure No. PPP-lX-MT-W77, dated July 17, 1978.
No items of noncompliance were identifie.
A hydrostatic test of the service water pipe system 2-SW-1801-03-24 in Unit 2 was. witnessed by the inspector. He examined the test engineer's procedures, Piping Test No. SW-4, and verified that the test was being performed in accordance with them.
No items of noncompliance were identified.
6.
