1.
It was alleged that cable samples returned from Susquehanna Steam Electric, Units
and 2, to American Insulated Wire Corporation (AIW) for evaluation, were determined to have below specification insulation thickness and that AIW management directed the test results obtained during July and August, 1979 to be changed so that readings would be within specification requirements.
2.
It was alleged that production age testing of cables, as required by specifications, had not been performed by AIW.
Site'Investi ation An investigation was performed at the Susquehanna Site Units
and
on November 8-9, 1979.
This investigation included an examination of the pertinent documentation associated with the AIW Corporation purchase order listed below:
Purchase Order 8856-E-130A; Technical Specification for 600 Volt Power and Control Cable E-130,. Revision 7, dated October 18, 1979; Receiving Reports which included AIWs Dimensional and Physical Test Data; Franklin Institute Research Laboratories "gualification of Electrical Cables,"
Report F-C4197-2 dated December 1975; and,
Nonconformance Reports associated with AIWs purchase order 8856-E-130A.
In addition to the documentation review, the investigator discussed the receiving, storage, installation and testing of the cable with site personnel.
In reviewing the Franklin Institute Research Laboratories (FIRL)
report No. F-C4197-2 entitled "gualification of Electrical Cables For A Loss-of-Coolant Accident," dated December 1975, the investigator could not determine if the AIW cable configurations in licensee's approved documents 8856-E130A-147-1 dated August 17, 1979 and 8856-E130-A-1-1 dated February 5,
1975 were qualified by that report.
This matter is considered to be unresolved.
(79-38-01 and 79-20-01).
It will be examined further during routine inspections.
F.. 'IIRC'Fi 'di An investigation was conducted. at the American Insulated Wire Corpora-tion, (AIW) plants in Pawtucket, Rhode'Island and South Attleboro, Massachusetts on November 25-28, 1979.
1.
Alle ation'No.
~
The investigators examined the cable test data sheets that were available and interviewed the laboratory technicians that. performed the testing and data recording on the cables returned to AIW from Susquehanna Units
and 2.
The investi-gators also interviewed the secretary who did the typing of the results of AIW report on the Susquehanna cables dated October 26, 1979.
The test data appeared to be recorded with only minor correc-tion and use of "white-out" by the laboratory technicians.
In interviewing the laboratory technicians, they stated that they changed'he data only when they made an error in reading or transcribing data from one sheet to another.
One laboratory technician did most of'the data transcribing and to the best of: his. knowledge, he did not use very much "white-out."
Both laboratory technicians stated that they were never. told by management'r anyone else to change or correct any result that was out of specification.
They both.stated that they were not'given any instruction other than to record the results they found during the test progra The secretary that typed the data stated that she could recall that "white-out" had been used on some of the hand written sheets, that had been destroyed after typing,, but that it-had been used on very few entries on the sheets.
The Technical Director that supervised the technicians who performed the test measurements stated to the investigators that he had never instructed the technicians to change any test measurements.
R.
~NRC'Ri'Ri Inspection, by the investigators, of the available test data results on'he returned cable samples from Susquehanna did not indicate excessive use of "white-out," nor data changing.
The laboratory technicians that performed the testing and data recording stated that they were never directed by anyone at AIM to change test data results.
The secretary who did the typing of the report from test data sheets supplied by the laboratory technicians also stated that she did not see excessive use of "white-out" to change data readings.
The NRC investigation found no information or evidence to substantiate the above allegation.

The NRC investigators questioned the laboratory technicians on their use of ovens in the performance of age testing.
The ovens that are located. in the receiving laboratory at the Pawtucket',
Rhode Island plant are used by the laboratory technicians and by the quality control organization.
Both laboratory technicians stated that they do not perform any production type age tests, and that they only use the ovens as, part of their research or receiving responsibilities.
Production verification for age testing is performed by the quality organization at the Pawtucket Plant and during this verification effort they use the same ovens that the laboratory technicians use.
Since age testing of production cables is performed at both the So'uth Attleboro, Massachusetts and Pawtucket,'Rhode Island Plants, the investigators went to both plant ~
At the South Attleboro, Massachusetts Plant, the investigators interviewed various quality personnel and-their use of the ovens in association with age testing.
The production ovens that.,are used for testing were in operation at the time the investigator was there.'ne oven was being used for age testing cables for a nuclear generating power plant contract which started testing on November 21, 1979, and was due out on November 28, 1979.
The investigator discussed the operation of the ovens with the gC personnel and determined that they knew the requirements of aging and they understood how to use the ovens.
The investigator also verified that the oven equipment was calibrated and within specifications.
The investigator randomly selected records from the quality control file data on Dimensional and Physical Test Data Sheets on cables tested from June, 1978 through October, 1979.
The investigator verified that the data recorded complied with the specification requirements of the material being tested.
The investigator specifically verified that the age testing and oil immersion tests were performed.
The investigator on his return to the AIW plant in Pawtucket, Rhode Island, inspected the ovens that are located in the receiving laboratory.
No age testing was being performed in these ovens during the investigation, but a life test on materials was in progress in one oven.
The investigator examined the Dimensional and Physical Test Data Sheets that were associated with the cables that had been tested in the ovens located in the receiving laboratory area.
A random selection from the quality control file data sheets from June 1978 through November 1'979 was made by the investigator.
The investigator'erified by discussions with quality control personnel and an examination of the test data sheets that production age tests were performed and data recorded by quality control personnel using one of the ovens located in the receiving laboratory.
The investigator verified that American Insulated Wire Corporation was following the requirements of the following documentation at both the Pawtucket, Rhode Island and South Attleboro, Massachusetts Plant Standard Operating Procedures:
SOP <8; Control of Purchase Materials, Equipment and Service; b.
SOP 815, Inspection,. Test and Operating Status; SOP 812, Test Control; SOP Ill, Inspection; SOP
<13', Control of Measuring and Test Equipment; SOP 818, guality Assurance Records; and, SOP <20, Operating Procedures and Use of Testing Equipment.
~NRC Fi di Inspection by the investigator verified that the aging ovens at the two AIW plants were functional, within calibration and controlled by the quality control organization as indicated in AIW SOP 813 entitled "Control of Measuring and Test Equipment."
An examination of the data recorded on the Dimensional and Physical Data Sheets in the AIW quality
.
control files from June, 1978 through November, 1979 indicated that age testing, as well as other tests, had been performed and test results signed by the quality control inspector.
The NRC investigation found no information or evidence to subtantiate the above allegation.
G. Unresolved Items Unresolved items are matters about which more information is required to ascertain whether they are acceptable items, items of noncompliance or deviations.
