Subject:
V. C. Summer Nuclear Station Unit #1 License CPRP-94, Reportable Item in Accordance with 10CFR50.55(e),
UT Requirements on Class 1 Pipe Gentlemen:
On April 14, 1980, the Region II Principle Inspector (T. Burdette) was notified of a potential reportable item dealing with procurement control of ASME Code Class 1 piping.
Mr. Burdette was again contacted on May 5, 1980, and informed that there was no safety significance involved with this item.
Therefore, SCE&G considered the item no longer reportable. During this second discussion, Mr. Burdette recommended that this 30 day formal report be sent to summarize what had trancpired relative to this subject.
i Nature of Condition I
During SCE&G/QA evaluation of a vendor documentation package prior to releasing material for shipment, it was discovered that material had been ordered from the vendor Hub, Inc., on SCE&G purchase order Q247690 without proper ultrasonic testing stipulated.
In particular, ASME Code Class 1 piping was ordered to the 73 addenda to which the plant is being built without the inccrporation of Regulatory Guide 1.66 into the order to obtain a four way UT scan.
It was determined that during a review of a previous purchase order Q248355 with McJunkin Corporation, a similar discrepancy was detected.
In the case of purchase order Q248355, no material was released for shipment at final inspection as the vendor surveillance program caught the discrepancy. For purchase order Q247690, however, the discrepancy was detected on the second shipment, meaning that 108 feet of 1" schedule 160 stainless steel pipe was released for shipment to the Site on an order that did not contain proper UT requirements.

Mr. Jame3 P. O'Rsilly Prat 2 May 19, 1980.
Cause The cause of the purchase orders being placed to original plant ASME Code editions without the imposition of Regulatory Guide 1.66, is attributed to the current status of the ceamitment to the Regulatory Guide contained in the FSAR. The FSAR indicates only that
'the Regulatory Guide has been withdrawn and does not delineate that it was withdrawn because the four way scan was incorporated into the Code in 1977. :As such, it appeared to those requisitioning material that the Regulatory Guide was not required.
' Actions to Correct' Conditions When'the conditions were discovered, a status of the 108 feet of pipe shipped on Q247690 was obtained. The pipe was still in the SCE6G warehouse where it was placed on hold. A review of all purchase orders ever placed for cede material was conducted.
It was determined that 4 of 55 purchase orders ordered Code Class 1 pipe and/or fittings to the 73 Code without imposition of Regulatory Guide 1.66.
Only two of the four orders contained pipe. These two were the ones previously detected at final inspection indicated above. Further investigation revealed 1) that all Class 1 fittings released and shipped on all four orders had_ received appropriate Regulatory Guide 1.66 NDE, 2) pipe on purchase order Q248355 which was still at McJunkin had not received the four way scan, and 3) the 108 feet of pipe shipped and the 60+ feet remaining to be shipped from Hub on purchase order Q247690, had received the four way scan as it was manufactured to current code editions and certified to the 73 Code as required in the purchase order.
Purchase order Q248355 was changed to require re-====4n= tion of the pipe pending shipment to include a four way scan. The pipe on i
hold in the SCE&G warehouse was released for use, and the balance of pipe on purchase order Q247690 was released for shipment.
Safety implications i
There are no safety implications associated with this item. The 108 feet of pipe shipped on the incorrect order that was not detected by the QA program did receive the proper NDE. As such, had the condition gone uncorrected, it would not have affected adversely the safety of operations of the nuclear power plant at any time throughout the expected lifetime of the plant.
Corrective Action to Prevent Recurrence q
The individuals involved with requisitioning the Code Class 1
~
~ asterial, and reviewing the requisition for acceptability for order placement, were those who investigated the problem and obtained
+
resolution. It is believed that this involvement will prevent recurrence in the future on their part. No further corrective action, such as

Mr. James P. O'Reilly Paga 3 May 19, 1980 changing the FSAR is being contemplated based on the status of Code Class 1 procure:nents remaining to be made with respect to construction need.
SCE&G believes the actions outlined above clearly indicate adequate resolution of the problem that had no safety implications. All actions taken regarding this item are available for NRC review, should it be necessary. Should further information be required, please contact us.
