P. O. Box 208 Wichita, Kansas 67201 Gentlemen:

This refers to the inspection conducted by R. G. Taylor and other personnel of this office during the period January 15-25, 1985, of activities authorized by NRC Constquction Permit CPPR-147 for the Wolf Creek Generating Station, and to the discussion of our findings with Mr. R. M. Grant, and other members of your staff at the conclusion of the inspection.

Areas examined during the inspection included followup on previous inspection findings, IE Bulletins, construction deficiency reports, and selected concerns reported by your construction self assessment team. Within these areas, the inspection consisted of selective examination of procedures and representative records, interviews with personnel, and observations by the inspectors. These findings are documented in the enclosed inspection report.

Within the scope of the inspection, no violations or deviations were identified.

Should you have any questions concerning this inspection, we will be pleased to discuss them with you.

Sincerely, Original Signed By:

6. Pipe System Cleanliness (Internal)

During a review of KG&E's NCRs and CARS, the NRC inspectors noted apparent recurrences of deficient conditions with respect to pipe cleanliness requirements. It was determined that these deficient conditions had been identified in numerous surveillance reports, NCRs, and CARS since as early as 1979, and on two occasions (June and November 1980), stop work orders were issued due to the apparent ineffectiveness of various corrective actions.

CAR.No. 7 was initiated on November 20, 1980, because " specification requirements for piping cleanliness are not being met. Corrective Action Report No. 6 did not result ~in actions which maintained the required levels of piping cleanliness." The biggest concerns related to foreign object contamination; i.e., nuts, bolts, Q-tips, chips, etc., and the use of Dissolvo welding tape, a high halogen content tape used for holding in place welding purge dams on austenitic stainless steel piping. The foreign object contamination could be removed during the normal pipe

system flushes; however, it was determined Prior that the1, to July tape or its 1980, residue Dissolvo could not be removed in this fashion. _

tape was used to form purge dams in stainless steel piping without Between July 1, 1980, and March 18, documentation verifying its . removal.

1981, (when a SNUPPS directive was issued to cease the use of Dissolvo welding tape), the use of the tape and its removal was documented.

A program was initiated to identify all stainless In addition to steel piping reviewing systems in documentation which the tape may have been used.

showing where Dissolvo tape had been used, a visual inspection was undertaken for all other stainless steel piping in which.the tape may have been used. KG&E, in correspondence to DIC dated April 30 and July 13, 1982, directed that where the presence of tape is identified, special cleaning The correspondence including hydrolase cleaning would be performed.

further directed that a minimum hydrolase pressure of 5000 psi be used and that a pipe cleanliness monitor and Level II QC inspector coordinate, witness, and document the inspection and cleaning.

This inspection and cleaning activity, in conjunction with generic flushes (removal of construction contamination from the systems by velocity flushing) and proof flushes (verification of both chemical and particulate cleanliness) became the basis for closing CAR No. 7 on November 27, 1984.

In order to assess the validity of the basis for closing out CAR No. 7, the NRC inspectors reviewed water quality data sheets showing results of the chemical analyses performed during proof flushes. The data sheets from 81 sections of 8 piping systems showed that the halide content (chlorides and fluorides) was much less than the maximum permissible Therefore, the amount and the overall water chemistry is acceptable.

basis for closing CAR No. 7 appears to be proper.

7. Exit Interview An exit interview was held on January 25, 1985, with personnel noted in paragraph 1 to discuss the scope of the inspection and the findings -

therefrom.
