NRC Independent Measurements The NRC will perform an independent verification inspection at Nine Mile Point Nuclear Power Station, Unit 2 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 yours and other construc-tion sites.
The inspection onsite wi 1,1 begin on December 9,
- 1985, and will conclude on December 20, 1985.
Welds will be selected by.the NRC Resident Inspector for examination 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 document packages be in the NRC Region I office by November 22, 1985.
The data packages will be reviewed by the Regional office for completeness and technical content.
We will update our NDE procedures to be consi stent and with your committed codes and standards.

SUPPLEMENTAL NDE VAN INFORMATION ATTACHMENT B 1.
NDE Van Su ort Re uirements Me 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.

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.
cd 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.
