s. -a, MAY 2 81985 Docket No. 50-443 Public Service Company of New Hampshire ATTN: Mr. Robert J. Harrison President and Chief Executive Officer P. O. Box 330 Manchester, New Hampshire 03105 Gentlemer.:

Subject:

NRC Independent Measurements The NRC will perform an independent verification inspection at Seabrook Nuclear Power Station, Unit 1 using the NRC Nondestructive Examination (NDE)

Van and contractor technicians under NRC direction. Construction activities and materials will be sampled through nondestructive examinations as a supple-ment to our existing inspection efforts. Similar nondestructive examinations by the NRC have been performed on a routine basis at other licensee construction sites.

The inspection onsite will begin on July 15, 1985, and will conclude on July 26, 1985. Welds will be selected by the NRC resident inspector for exami-nation by the NDE van team. We request that documentation packages be prepared by your staff for the selected welds. Additional information on the requested document packages is provided in Attachment A. It is requested that all docu-ment packages be in the NRC Region I office by July 1,1985. The data packages will be reviewed by the Regional office for completeness and technical content.

We will update our NDE procedures to be consistent and with your committed codes and standards. All documentation supplied by your staff will be returned, upon request, at the conclusion of the inspection.

- Members of your staff will be kept informed of our inspection progress and sig-nificant findings. An exit meeting with you or members of your staff will be conducted on July 26, 1985, in accordance with our normal procedures. The evaluation of examination results and preparation of an inspection report will be completed and the results of the inspection will be transmitted to you through the standard NRC inspection report. Additional information relating to the NDE van activities at your facility are discussed in Attachments B and C.

DATA PACKAGES - ATTACHMENT A After the welds have been selected for NDE inspection, we request that you prepare a package containing the following on each weld:

Inspection Report Weld History (QC History)

' Material. Certifications for base materials Weld Wire Certifications Piping drawings, isometric of weld locations NDE Reports on all NDE performed NDE Procedures for RT, PT, MT and VT Bolt Torquing Procedures (Structural and Pipe Hangers)

Piping and Installation Procedure (only section that specifies code and addenda)

The assembled packages should be forwarded to:

SUPPLEMENTAL NDE VAN INFORMATION ATTACHMENT B

1. NDE Van Support Requirements We request that the NRC-NDE Van be positioned as near as practicable to the containment area entrance to facilitate the performance of inspec-tions.

a. The van requires the following connections while sited at your facility:

Site water with a garden hose connection - this water is-for film rinse. ,

Requirement for film rinse water drain (continual). No chemical disposal will occur from the van without prior concurrence from appropriate licensee personnel. At the end of the independent inspection, the NRC needs to dispose of the film developing chemicals prior to moving the van from the site.

Two 30 amp, 110 volt circuits are required for operation of the van,

b. The van will contain PT and MT approve materials. The team will need two rolls of your chemically approved tape and two approved markers for identifying welds and marking weld areas.

c. It will be necessary for you to remove the paint, rust or other mate-rial that could interfere with PT or MT on the selected welds. Also, we will need scaffolding erected and insulation removed for access.

2. Administrative Information

a. The radiation source will be a nominal 100 curie IR-192 source. This source is licensed by NRC, but owned by the NRC contractor.

b. The names of the NRC and contractor NDE personnel will be supplied to you by Region I. Clearance for these personnel is necessary.

Attachment B (Continued)

c. We request that you hold a mini-radiation safety training course for the NRC NDE personnel. This course should familiarize the personnel with your facility and procedures and should not exceed 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> in length.
