' b 9p OCT 181985 Docket No. 50-455 Commonwealth Edison Company ATTN: Mr. Cordell Reed Vice President Post Office Box 767 Chicago, IL 60690 Gentlemen:

Subject:

NRC Independent Measurements This letter is to confirm the NRC's plan to perform an independent verifica-tion inspection at the Byron facility, Unit 2, using the NRC NDE van and contractor technicians under NRC direction. This plan was discussed by Julian Hinds, of the NRC Region III staff, with R. Tuetken and others of your staff.

We consider this inspection to be an independent verification of construction at the Byron facility, Unit 2. Construction activities and materials will be sampled through nondestructive examinations as a supplement to our existing inspection efforts. - Similar future nondestructive examinations by NRC are planned on a routine basis at other licensee construction sites.

This inspection at the Byron facility, Unit 2, is expected to begin on October 28, 1985, and will be completed on November 8,1985. We have requested i docur:entation packages to be prepared by your staff for each of the welds selected. Additional information on the documentation selected for inspection is provided in Attachment A. We understand by letter dated October 10, 1985, from J. T. Porter, CECO Project Construction Department, Byron Station, to Harry Kerch, USNRC, that this information has been forwarded. NRC will review your documentation packages and update NRC procedures to be consistent with your procedures. All documentation supplied by your staff will be returned upon request at the completion of the inspection. Further information regarding Van logistical needs and the scope of the inspection is provided in Attachments B and C.

Members of your staff will be kept informed of our inspection progress and significant findings. An exit meeting with you or members of your staff will be conducted on November 8,1985, in accordance with our normal procedures.

SUPPLEMENTAL NDE VAN INFORMATION I

ATTACHMENT B

\

l 1. NDE Van Support Requirements i

l 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.

1 I a. Thi van requires the following connections while sited at your facility:

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

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 s$te.

Two 30 amp, 110 volt circuits are required for operation of the 4 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.

1 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.

l -

2. Administrative Information i a. The radiation source will be a nominal 100 curie IR-192 source. This j 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 III. 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,

d. A camera site pass will be needed for a Canon AE-1, 35 mm, camera, Serial No. 1969401.

e. The NDE personnel will be using 5 watt Motorola radios on the site; the frequency used by the NRC is 165.6625 MHz.
