The maintenance of a pressurized inert gas blanket on the accumulator tanks was spot-checked, as was the overall status of material preservation in the Auxiliary Building anc. Containment.

Interviews with Craf tsmen On this inspection, the inspectors initiated the trial implementation of a formal craftsmen interview program, announced to the licensee by letter, dated November 1,1979. A total of eighteen craftsmen and QC inspectors were privately interviewed regarding the quality of construction, various code requirements, and any irregularities they may have noted or concerns they may have about the safety-related work in which they are involved.
The confidentiality of all conversations and the anonymity of the source of all discussion items were both stressed and maintained.
Since most of the individuals interviewed were selected from the
'
boilermaker trade, the quality of construction and technical issues relating to the erection of the containment and fuel pool liners were discussed.
Specific discussion items amenable to immediate inspection ' follow-up were either brought to the attention of the licensee for further action, or checked by the inspectors during additional. inspection-tours of the applicable work areas, as warranted.
The conduct of these craftsmen interviews, immediate follow-up by the inspectors, and subsequent telephone calls with a licensee representative on December 31, 1979 and January 3,1980 have resulted in the identification of no items of noncompliance during the course of this inspection.
