Functional or Program Areas Inspected
,
1.
Licensee's Physical Inspection and Verification of In-Place rafety Category I Pipings and Hangers A 100% review of 101 completely installed hanger packages was com-pieted.
Installed configuration was verified consistent with the design drawings and all spring type were temporarily locked com-pressed. S&L hanger drawings were used for the verification program.
Twenty-four (24) additional completely installed hangers not on the list were found and subsequent package review is scheduled at a later date. A total of 719 hangers were noted. Fifty-seven (57) random
,
samples of selected hanger field welds were inspected to establish an overall 95% reliability with 95% confidence factor.
The piping verification is still not complete. The Physical Survey Team has reviewed approximately 19% of Cherne traveler packages for the in place pipe.
l Part of the program for piping weld procedure verification requires the Physical Survey Team to examine the S&L piping design tables and S&L pipin and instrumentation diagrams and to document the findings o
as to the correctness of the piping design table used, pipe class and weld procedure for the type of material welded. The inspector i

noted that this procedure is apparently not followed in that the
'
Physical Survey Team uses a WPS natrix written by S&L to document
the basis of their findings. The licensen agreed to revise the procedure to incorporate the S&L issuance of WPS matrix.for use by the team for weld procedure verification. This item'is con-
,!
sidered unresolved pending licensee's issuance of an approved revision to the SPP-4 procedure incorporating the above comments.
(546/80-18-01)
No items of noncompliance or deviations were identified.
2.
Observation of Safety Related Componeet Installation The inspector noted on May 7, 1980 three (3) component cooling heat
exchangers on elevation 364, NB-1031 through NB-1033, not having
'
inert gas blankets as required by the manufacturer during storage.
Review of the contractor's (Cherne) Nonconformance Report No. 01360
-
indicates that the inert gas was removed on or before March 31, 1979;
}
prior to grinding activities on the pipe spools. On January 29, 1980, PSI issued a DCR No. C-014-80, but no resolution was recommended until March 7, 1980, when Westinghouse, in a letter to Mr. L. Peterson, PSI, recommended the use of desiccants. The inspector noted that the nonconformance was not promptly identified, nor was the Westinghouse recommendation promptly followed to correct the problem. This is considered an unresolved item and will be examined on subsequent inspection to determine licensee's action to prevent recurrence.
(546/80-18-02)
