ENCLOSURE Item 1:
"Based on a review of the attached lists of Ray Miller, Incorporated, customers who received apparently fraudulent materials (Attachments 1 and 2), and pertinent information obtained from any of these companies, either directly or indirectly:
(a)
Identify those companies on the lists that supplied materials or services to your facility (include subcontractors as well as major contractors); and (b) Determine whether any of the apparently fraudulent Ray Miller, Incorporated materials were provided to or used at your facility.
(c) Determine whether any of the apparently fraudulent material supplied to you was iristalled in safety-related systems at your facility, or is still in stock.
(d)
If other Ray Miller, Incorporated materials not listed in Attachments 1 and 2 have been identified by your own initiative, determine whether any was installed in safety-related systems at your facility, or is still in stock."
Response
(a) TVA's review included all vendors who were listed on TVA's Qua11 fled Suppliers List (QSL) at any time during the period from 1975 through 1979.5 TVA has identifled and questioned 19 companies that potentially could have supplied safety-related materials to TVA that were obtained through Ray Miller. These companies are listed below.
AFC0 Metals Bristol Metals, Incorporated Capitol Pipe and Steel Products Company Oravo Corporation ITT Grinnell Corporation Gulfalloy, Incorporated Guyon Alloys, Incorporated Hub, Incorporated Huntington Alloys, Incorporated Marmon/ Keystone Corporation McJunkin Corporation PBI Industries Piping Supply Company Taylor Industrial Supply Henry Pratt Supply Company
- Ingersol-Rand Company
- Leslie and Elliott Company
- Peebles Supply Company
- Permutit Company *
- As discussed in reference 4, these companies were not questioned until November 1987.
. c (b) Fifteen companies identified above have confirmed in writing to TVA that they did not furnish any material supplied by Ray Miller to TVA. As committed in reference 4, TVA will notify NRC if the remaining four companies indicate that any apparently fraudulent Ray Miller material was supplied to TVA.
(c) None of the apparently fraudulent material has ever been or is now in stock for use in safety-related systems.
(d) From this research, TVA has identified two items of material that were furnished directly by or through Ray Miller for use in a safety-related system at SQN.
These two items were furnished by Ray Miller of Decatur, Georgia. At SQN, these Ray Hiller materials used in safety-related applications are:
1.
Approximately 1 foot of 3/4-inch schedule 80 stainless steel pipe was used to manufacture a drain line on the unit 2 positive displacement pump discharge accumulator / damper at SQN.
2.
Three flanges were installed to blank the eductor trap lines in the aux 111ary waste evaporator at SQN.
No other Ray Miller material has been purchased by TVA for safety-related applications at SQN.
Item 2:
"For Ray Miller, incorporated, materials, both the NRC-identified apparently fraudulent materials listed in Attachments 1 and 2, and other materials identified by your own initiative, that are installed in safety-related systems of your facility:
(a) Evaluate the safety significance of the presence of these materials assuming the fraud is as identified in the attachments or assuming material failure.
(b) Determine the disposition of the installed material; e.g., use as is, remove and replace, etc."
Response
(a) For the positive displacement pump discharge accumulator drain line, TVA has determined that the use of the potentially fraudulent material is not a significant safety concern.
This is based on the fact that the positive displacement pump does not perform any accident mitigation function.
While the positive displacement pump discharge pipe tees into the Emergency Core Cooling System (ECCS) high head injection flow path, a check valve located between the discharge accumulator and the tee will preclude any degradation of the ECCS if the drain line was to break.
d
---,w
-,,--,,.---,.-,~
. t It should be noted that, with approximately 37 months of plant operating expertence since the drain line has been added, including operation at normal system pressure, no degradation of the drain line has occurred.
For the three flanges on the auxiliary waste evaporator, TVA determined that these should be replaced because significant radiological contamination could result from failure of the flanges.
(b) The disposition of the drain line is to use as is.
TVA believes that it is reasonable to expect no failure of the drain line; and, if the line did break, there would be no significant adverse consequences. The three flanges were nonconformed and have been replaced by maintenance request No. A126305.
(Note:
The auxiliary waste evaporator is no longer used at SQN, and it is being decommissioned.)
Item 3:
"For all material from Ray Miller still in stock, whether identified by item 1 or previously identified by your own initiative:
(a) Segregate into two groups:
(1) material included in the purchase orders listed in the fraudulent data file, and (2) all other material supplied by Ray Hiller, Incorporated, regardless of the branch office tha,t supplied the material.
(b) For the material included in the fraudulent data file:
(1) Discard the material, or (2) Tag or otherwise mark tha materials for use only in systems not important to safety.
(c) For material supplied by Ray Hiller that is not included in the fraudulent date file, do one of the following:
(1) Discard the material.
(2) Tag or otherwise mark the materials for use only in systems not important to safety, or (3) Subdivide material into groups of identical items and examine and test material in each group in accordance with either item (1) or (11), below:
(1) Perform sufficient comprehensive examinations and tests to qualify each group of material for use in systems important to safety.
If there are less than 10 identical items in the group, each item should be examined.
If there are 10 or more identical items, a statistical sampling plan may be used to demonstrate
. r with 90 percent confidence that 90 percent of the material conforms to the purchase specifications.
Groups of material found acceptable may be used as i
desired.
l (11) Perform comprehensive examinations and tests of a limited sample of each group of identical items. The minimum sample size is to be two items, or-10 percent of the items in the group, whichever is greater.
Examination and test of this limited sample does not provide a high degree of assurance that the entire group satisfies the procurement specifications.
NRC will compile the results of all the data received, determine the statistical significance of the results, and advise industry of the overall results and
' conclusions.
Therefore, a utility should not use this material in systems important; to safety until NRC's evaluation is complete."
Response
(a) All Ray Miller material that could be used in safety-related i
applications has been segregated from the safety-grade material stock or discarded.
(b) No apparently fraudulent material has been identified in stock.
(c) Same as (a) above.
Item 4: "Provide a written report describing the results of the actions in items 1 through 3.
Table 1 (Attachment 3) provides a suggested format for reporting the results of the examination and testing of materials."
Response
A written report is provided above. TVA did not opt to perform comprehensive examinations or tests on the suspect material, thus there are no results to report.
