General
.
This trip was made to inspect the new incore instrumentation system and the related documentation for the material quality, fabrication, installation, testing and disposal of the old system.
j 3.
Status At the time of this inspection the new incore system consisting of twenty-six (26) thermocouples and twenty-two (22) flux paths, had been installed and the closure head and upper structure were in place. The work being performed consisted of connecting the guide tubes to the drive mechanisms. No deficiencies were noted.
4.
Material Records l
Randomly selected material certificacions were examined for compliance
to the applicable requirements and for tracebility to the actual p a'r ts. No.deficiences were identified.
.
5.
Vendor Surveillance and Audits The inspector reviewed the extent of involvenait in the actual fabrica' tion of the incere system by the licensee. The inspector noted that audits, inspection trips and extended surveillance trips
