Class 1 Pipe Not Having 4-way Ultrasonic Examination i
Reference:
SCE6G Letter to Region II (Same Subject) dated July 30, 1980 Gentlemen:
SCE&G sent the referenc.ad letter to Regien II indicating a final report of 1 -
an item
- dealing with 4-way Ultrasonic Examination of class 1 pipe not being performed as required by Regulatory Guide 1.66.
In that letter we indicated that the current extent of the condition was approximately 20 feet of Ib" schedule 160 stainless-steel pipe,.and that to date the piping supplier in-dicated the condition was an isolated case attributable to human error. The piping supplier instituted an investigation on July 16, 1980' to determine the extent of-the condition and when SCESG filed the July 30 letter to Region II'it was felt that only the 20 feet of 1 " schedule pipe was involved. The piping supplier completed a review of all material requiring ultrasonic exam-ination on beptember 5,1980 and notified SCE&G that additional items did not receive the 4-way ultrasonic examination. SCE&G obtained the information on Gepten.ber 8,1980 and apprised Region II (E. Girard) via telephone that the scope had increased.
.In' addition, the piping supplier visited our site on September 9,1980 to present the final status which indicated that all items requiring ultrasonic testing were investigated. At this ti=e it was clso communicated to SCE&G that one 6".schedtle 160 SA 403 stainless fitting was -
not ultrasonically examined af ter heat treatment as required by the ASME Code.
Since this item did not specifically fit the - condition of missing 4-way - ultra-
. sonic examination as required by Regulatory Guide 1.66, Region II (J. Rausch) was apprised via'telephoac on September 9, 1980 that the fitting was also in-volved in the;pipicg suppliers ultrasonic examination problems.
This letter, therefore, is' written to supplement our letter of July 30, 1980
'to extend the scope of material involved to include approximately 40 feet of 6'.'.. schedule 160 stainless --steel pipe,.14 ~ feet of 2" schedule ' 160, and a' 6" schedule 160 stainless steel fitting, This' letter will also update current j

.f USNRC Pag 2 2 10/09/80 action we are taking to resolve the condition. The item has been assigned NRC item 80-23-01 by Mr. Rausch during a recent inspection visit.
Cause The cause remains as defined in our July 30th letter supplemented by oral indication from the piping supplier that when the ultrasonic examination was stipulated in the manufacturing planning stage, the person who did it was not cognizant that Regulatory Guide 1.66 was applicable to the order and therefore did not specify appropriate procedures to be used.
Safety Implications The safety implications remain as defined in our July 30 letter. Presently, however, the piping supplier is indicating that the piping may be able to be examined in place. This would enable SCE&G engineers to deter =ine accept-ability of the pipe and may possibly show there were no safety implications of the pctential reportable item; or confirm our previous report that safety implications cannot be ruled out.
Actions to Correct Conditions The additional pipe and fitting identified by the piping supplier as having ultrasonic examination omitted are documented on a site Nonconformance Notice
- 3393. This is in addition to NCN #2206 which documented the original 20 feet of pipe. The piping supplier is to perform ultrasonic examination of the pipe and fitting on site and present results to 2ngineering. The pipe will either be accepted or replaced, based on ultrasonic examination results and Engineering evaluations.
Corrective Actions to Prevent Recurrence The corrective action to prevent recurrance is as defined in our July 30th letter with the exception that we are now sure that all supplied items net properly ultrasonically examined have been identified.
SCESG believes we now have within the site conformance program all items having ultra-sonic examination missing, along with means to examine, evaluate and take actions to provide acceptability or replace questionable product. As such, since all necessary actions have been identified and are in the process of being implemented, we consider this supplemental report a final report on this item.
The results of all actions taken will be available at the site for NRC review. Should further information be required, please contact us.
Very truly yours, T. C. Nichols, Jr.
