Status of Previous Inspection Findings _:
1.
(Closed) Nonconformance (85-01. Item B.1): The test technician had not initialed and dated corrections to recorded data on data sheets for MJO 558-1572. The NRC Inspector reviewed several data sheets from two MJO Files to verify that corrections to recorded data are now being initialed by the test tectinician.
2.
(Closed) Nonconformance (85-01, Item B.2): The test technician had not initialed the appropriate column of Job Traveler Forms (JTFs) for MJ0's 558-1720, 558 1686, and 557-1382 when it had been ascertained that a test had been conducted and completed in accordance with applicable specifications. The NRC Inspector reviewed JTFs for two MJO Files to verify that the appropriate column of the JTF are now being initialed by the test technician after test had been conducted and completed.
3.
(Closed) Nanconformance (85-01, Item B.3): The audit report for the May 1984 corporate quality internal audit was not issued within thirty days of the conclusion of the w dit, did not request a response date for correctiva action, and there was no documented evidence to indicate that the reouired follow-up had been performed by the lead auditor. The NRC Inspector verified that the 1985 corporate audit report was issued in a timely manner and that a follow-up was made by lead auditor of the corrective actions taken in response to the 1984 corporate audit.
4.
(Closed) Nonconformance (85-01, Item B.4):
NTS test plans for test procedures did not list test equipment requirements for MJO 558-1572 or list all test equipment accuracies for MJ0s 558-1572 and 557-1382.
The NRC Inspector reviewed two MJO Files ano verified that test equipm(nt requirements and their accuracies are now listed as an attachment to the test procedure.

Other Findings or Comments:
1.
Observation of testino activities PJ0-558-1711 - Post-LOCA functional testing was being conducted for Consumer Power on three Rosemount RTDs for use in Palisades Nuclear Power Plant. The NRC Inspector and Sandia consultant (NRC inspection team) witnessed portions of the opening of the chamber, removal of the specimens and performance of post-LOCA functional tests.
The post-LOCA functional tests consisted of a three-point calibration check (triple point of water, boiling point of water corrected for atmospheric pressure, and the freezing point of lead).
During this witnessing, the NRC inspection team identified the nonconformance described in paragraph B.2.
With respect to B.2, the NRC inspection team reviewed selected data from the post LOCA functionals as well as data from all previous functional tests.
No problems were identified with this data.
However, the functional tests prescribed in TP 558-1711 were not followed precisely by the test technicians.
TP 558-1711 required that measurements during the three-point calibrations should be taken every minute until two consecutive readings differed by 0.02 ohms or less, indicating stabilization. Only one readino was recorded at each of the calibratirn points.
However, interviews with the test technicians indicated that they always waited for a stable reading before taking the data.
l 2.
Technical Evaluation - The NRC inspection team performed a technical evaluation of MJO 558-1711 for qualification testing of Rosemont RTDs.
The NRC inspection team reviewed the EQ process prescribed in TP 558-1711 and reviewed test results, including the bases for accelerated thermal aging and radiation and verified calculations.
TP 558-1711 and related engineering documents were examined to verify the following:
a.
Adequate test instrumentation and their accuracies were described and used to meet the requiremens of IEEE-STD-323/1974 b.
Equipment interfaces were addressed.
l c.
Test acceptance criteria were established as described in the test specification or in the design engineering l
documents, such as calculations and engineering letters to meet the requirements of IEEE-ST0-323/1974.

PAGE 5 of 6 d.
Same equipment was used for all phases of testing.
e.
Environmental conditions were established and described (e.g., pressure and temperature profiles, and thernal aging factors were consistent with those outlined in the test specifications or test plan),
f.
Test results were adequately reduced and evaluated against established acceptance criteria described in customer test specifications or purchase orders.
g.
All prerequisites for the given tests as outlined in the test specification had been met.
h.
Test equipment included a description of all materials, parts, and subcomponents.
1.
Notice of Deviation Forms were properly documented, j.
Appropriate margins were applied.
k.
10 CFR Part 21 imposed on procurement documents.
During the above review and evaluation, the NRC inspection tean identified the nonconformances in paragraph B.1.a, 0.1.b, B.4, 8.5.a.
B.S.b, B.S.c.
With respect to B.1.a. the NRC inspection team requested a copy of NTS's detailed operating procedure for the steam supply system used for EQ testing.
Interviews with the Nuclear EQ Manager disclosed that nn procedure existed.
With respect to B.1.b, the NRC inspection team visually examined a resistance bridge arrangement which was used for monitoring the RTD nutputs during LOCA testing.
The outputs of the RTDs were compared at two points to the chamber temperature and the reference temperature which was recorded by a stripchart recorder.
The method of connection of the RTDs through the resistance bridge arrangement to the stripchart recorder was not documented in TP 558-1711.
' ORG NIZATION:
NATIONAL TECHNICAL SERVICES HARTWOOD, VIRGINIA REPORT INSPECTION N0.: 99900914/85-02 RESULTS:
PAGE 6 of 6 With respect to B.4, the NRC inspection team reviewed Purchase Order 631-054814C for stress analysis and determined that the provisions of 10 CFR Part 21 were not specified by reference on the purchase order as required by Appendix A, page 27 of the QCM.
Interviews with the Nuclear Manager indicated however, that 10 CFR Part 21 was included as an attachment to the purchase order. A copy of the attachment was obtained from purchasing and provided to the NRC inspection team.
With respect to B.S.a. the NRC inspection team determined that NTS did not provide any references or documentation supporting their choices of activation energies.
Specific concern was expressed by the NRC inspection team for a choice of 1.22 ev for an activation energy for ethylene propylene.
(EPRI) Electric Power Research Institute data indicates a range of activation energies of 0.70-1.28 ev for various forms of ethylene propylene with a conservative choice of 0.90-0.95 ev based on specifics given for the different formulations.
With respect to B.S.b, the NRC inspection team reviewed a data calculation sheet showing the amount of each chemical used in mixing the chemical spray solution.
The NRC inspection team requested documentation which would verify that the chemical spray solution used during design basis event testing was mixed as prescribed in the data calculation sheet.
The Nuclear Manacer was unable to provide the requested documentation.
With respect to B.5.c. the NRC inspection team reviewed a stripchart recording taken during the LOCA test. The stripchart recorder used identical blue pens which recorded two temperature measurements.
It was determined by the NRC inspection team that the two blue traces that overlapped on the stripchart prevented clear identification of which trace was which.
3.
Calibration of Test Equipment - The NPC inspection team inspected several pieces of measuring and test equipment used for data acquisition during the LOCA test of the RTDs.
The NRC inspection team observed that the calibration interval established on the calibration label of the outside laboratory wasdifferentfromthecalibrationintervalestablishedinNTS$
official equipment list for a Gould stripchart recorder.
This nonconformance is identified in paragraph B 3.
NTS responsible personnel corrected this nonconformance on the spot by placing a NTS calibration label on the stripchart recorder with the proper calibration interval identified.
