V. C. Summer Nuclear Station Unit #1 License CPRP-94, Reportable Item in Accordance with 10CFR50.55(e), Class 1 Pipe Not Having 4 Way Ultrasonic Examination Gentlemen:
On July 2,1980 a' ter attempting to contact Mr. C. R. McFarland at Region II without suc.ess. tha. Region II Resident Inspector, Jack Skolds, was notified of a reportable item relative to ASME Class 1 pipe being supplied, accepted and installed without the required 4-way ultrasonic examination contractually stipulated via Regulatory Guide 1.66.
The pipe was supplied by the piping supplier, Southwest Fabricating & Welding Company, Houston, Texas, released from the field by a SCE&G/QA agent and accepted on Site by
~
the Constructor's (Daniel Construction Company) receiving inspection. As such, the condition of pipe not receiving the 4-vay ultrasonic examination is considered to fit the definition of defect in 10CFR Part 21.
Nature of Condition Approximately 20 feet of li" schedule 160 stainless steel pipe was s
supplied as ASME Class 1 from the piping supplier in 1977. The con-tract with that supplier required Class 1 pipe to be UT examined in accordance with Regulatory Guide 1.66 (4-way) but the pipe was only 4
examined to ASME Section III criteria; which required only a circum-ferential examination for the contractual code edition of 1971 Edition with Summer 73 Addenda. A documentation review by a SCE&G/QA agent f.f c

l prior to shipment of the pipe failed to detect the deficiency and i-receipt inspection by the Constructor's ASME Code receipt inspection
?
~ program also failed to detect the deficiency. The deficiency was j
detected via documentation reviews currently being performed as part j
of generic corrective action taking place for various Code QC program breakdown problems (Reference letters to Region II dated April 18, 1980, March 21, 1980, and December 5, 1979).
Cause i
In the case of the piping supplier, it appears to SCE&G that a program deviation of some nature occurred wherein piping that was not 4
properly examined was presented for shipment. A letter was issued to the piping supplier to apprise them of the condition and request corrective action although the SCE&G purchase order with the supplier y
for piping is currently complete. To date, the supplier has aided in i
determining that the extent of the condition is currently only the
]
20 feet of pipe detected during the documentation review.
In the case of the SCE&G/QA agent reviewing the product prior to shipment as well as the Constructor's receiving inspection, there was a failure to perform and comply with procedures to verify material j
acceptability.

Safety Implications t
4 To determine the exact safety implications of this condition, i
Engineering would need to evaluate each of nine applications in piping i
systems where small quantities of pipe were installed on the assumption j
that because the UT exam was not performed, defects exist in the pipe and it would fail. On the other hand, the piping has not and can i
not be examined by 4-way UT to determine no defect exists. Therefore
'j i
the possibility of the condition having safety implications cannot j
be ruled out.
For this reason, the conditions are conservatively being classified as potentially reportable and will be corrected to i
remove any doubt as to product acceptability.
Actions to Correct Conditions Concurrent with the documentation review being performed in the ASME Code area, it has been concluded to date that only 20 feet of pipe was shipped in 1977 from the piping supplier without the proper UT examination. This condition was documented on a Site Nonconformance Notice (NCN 2206). Engineering disposition of this NCN is to remove and replace the questionable pipe.
If subsequent documentation reviews reveal more pipe in this category, NCN's will be generated and similarly dispositioned.

Corrective Actions to-Prevent Recurrence Due to the time frame under which the condition occurred, the individuals involved in shop surveillance and receipt inspection are no. longer associated with the project. The SCE&G/QA field agent is no longer-in business and the Constructor's receipt inspector is no longer at the SCE&G Site. Corrective Action in these areas is limited to cognizance of the condition by those involved with processing the NCN so that future attention to details will be given if similar circumstances arise.
In the case of the piping supplier, actions have been initiated I
by way of a letter to obtain corrective action to the problem identified, The purchase order for pipe with this supplier is currently complete p.3 and response on; their part cannot be mandated. To date, the piping supplier has indicated that the condition is an isolated case attri-budable to humin error. Response from this supplier giving corrective action for this condition will be evaluated by SCE&G and utilized in y
g,I terms of future use of the supplier.
(
4.,.
SCE&G believes actions outlined above will adequately resolve the problem y
encountered with 20 feet of pipe not having the required 4-way UT examination.
Since all necessary actions have been identified and are in the process of being implemented, d consider this a final report on this item. All actions taken will be available at the construction site for NRC review. Should further
~
information be requiimed, please contact us.
