OTHER FINDINGS AND COMMENTS:

1.

Four (4) test programs relating to the Environmental Qualification (EQ) of equipment were examined. These programs were examined te verify the following:

Required test instrumentation with accuracies described, a.

met the requirenents of IEEE-STD-323/1974, b.

Equipment interfaces were addressed.

Test acceptance criteria was established as described c.

in the test specifications or in the design engineering letters to meet the requiremerits of IEEE-STD-323/1974.

d.

The same equipment was used for all phases of testing and represented a standard production item, Environmental conditions were described (e.g., pressure e.

and temperature profiles, and thermal aging factors consistent with those outlined in the test specifications ortestplan).

f.

The test results were adequately reduced and evaluated against acceptance criteria described in the test specifications or purchase orders.

9 All prerequisites for the given test as outlined in the test specifications were met.

h.

The description of test equipment included all materials, parts, and subcomponents.

Notice of anomaly reports properly documented the observed condition and reports were properly dispositicned.

j.

Appropriate margins were applied as required by test specifications.

1.

EQ of GE EB-5 and EB-25 Terminal Blocks for use in Niagara Mohawk Power Company's Nine Mile Point, Unit 1.

The final test report 17775-1 on the Terminal Blocks was examined. The test subjected the terminal blocks to two (2) temper 4T.ure transients, however the second and higher of the temperature transients was for information only.

In examining test report 17775-1 it was noted that in some cases recorded test data was corrected by writing over the originally recorded data. When questioned about Wyle's policy for correcting test data, the inspectors were informed that corrections are to be made by lining-through original data, initialing and writting in new data. Wyle was already in the process of revising Quality Directive (OD) V-1, Reports, Test Procedures and Plans to recognize line-throughs and initials as the only acceptable method of correcting test data.

No nonconformance or deficiencies were found during the examination of this EG program.

2.

EQ of Raychem WCSF-N Nuclear Cable Splices and Okonite Tapes ds installed on various wire insulations at Ccmmonwealth Edison Company's LaSalle County Station.

The qualification plon for this program was examined. This program consisted of 20 different configurations of cable splices which could be found at LaSalle County Station. The splice configurations varied in Raychem sleeve or tape over-lap and in the types of leads spliced together.

No nonconformances or deficiencies were found during the examination of this EQ program. The final report will be examined upon completion of the testing.

E0 of Lewis Engineering Electrical Cables installed at Indian Point 2 and 3 Nuclear Power Plants.

The EQ test plan and test procedure of this program were examined. The testing had just been completed and the raw test data was examined.

This program intends to qualify the Lewis Engineering cable used at Indian Point 2 and 3 Nuclear Power Plants.

No nonconformances or deficiencies were found in the test plan, test procedure or data examined. The final test report will be examined during a later inspection.

4.

E0 of Target Rock SPV Air Operators and Dual Solenoid Valve Assemblies for General Electric.

Test report 47732-1 was examined for this program. The purpose of this EQ program was generic qualification of Target Rock SRV Air Operators and Dual Solenoid Valve Assemblies. The test consisted of aging and accident simulation of three configurations of air operators and one dual solenoid valve assembly with a seismic test of the completely assembled SRV. The three air operators were as follows:

(a) Specimen #1 - EPOM 0-ring and diaphragm (b) Specimen #2 - Silicon 0-ring and diaphragm (c) Specimen #3 - Viton 0-ring and Silicon diaphragm The test report defined twelve function tests that were performed on specimen #3 with solenoid valve assembly af ter each test segment.

(a) Solenoid coil resistance (b) Coil insulation resistance (c) Pickup voltage (d) Dropout voltage (e) Actuator opening time for different voltages and pressures (f) Actuator closing time for same voltages and pressures as for actuator opening (g) Minimum pressure to stroke actuator (h)

Pilot rod stroke

CRGANIZATION: WYLE LABORATORIES HUNTSVILLE, ALABAMA REPORT INSPECTION NO.: 99900902/86-01 RESULTS:

PAGE 5 of 6 (i) Solenoidvalveleakage(valveclosed)

(j) Actuatcr assembly leakage (k) Solenoid coil inductance (1) Dropout solenoid transition.

Only function tests (d), (e), (f), (g) and (i) were per-formed on specimens #1 and 2 after each test segment using the valve assembly.

In examining this test program the inspection team noted some concerns with three of the test anomalies.

(a) During the post aging functional test, specimen #1 exceeded the actuator leakage criteria. Examination revealed that the diaphragm nut was under torqued.

Corrective action resulted in torquing the diaphragm nut to a value above the manufacture's specification to stop the actuator leakage. No justification or analysis was given for the final torque value.

(b) During the accident simulation, the diaphragm of speci-men #3 failed and was replaced twice. Justification for continuing the test was that an identical diaphragm was installed in specimen #2 and could be used to establish qualification. However specimen #2 had not been mechanically cycled per IEEE STD 382-1980 as had the specimen that failed.

Sufficient justification for the diaphragm qualification was not given.

(c) During the later stages of the accident simulation the spring cartridge / air operator seal failed three (3) times, once in specimen #2 and twice in specimen #3.

On all occasions, the acceptance criteria for leakage of the actuator was exceeded. The seal was a standard Target Rock part and had not been irradiated or aged.

Replacement was justified on the basis that the seals were not part of the specimen but part of the test fixture and therefore did not affect the test. There was no discussion in the test report of why the failure of a part which affected the acceptance criteria was not considered an E0 concern.

ORGANIZATION: WYLE LABORATORIES HUNTSVILLE, ALABAMA REPORT INSPECTION NO.: 99900902/86-01 RESULTS:

PAGE 6 of 6 During the examination of this test program no nonconforn-ances or deficiencies were found in the programmatic review Wyle Laboratories testing.

II. The inspection team examined selected areas of Wyle Laboratories Quality Assurance (CA) Program for compliance to Appendix B of 10 CFR Part 50. The inspection team then examined selected internal 0A audit reports, CA audit reports on outside suppliers of services and equipment, and purchase orders for outside services and equip-ment.

in examining the audit reports it was suggested that the addition of a section which addressed previous audit findings would be useful. Wyle Laboratories agreed with this suggestion and stated that they would incorporate this suggestion into future audit reports.

During the examination of Wyle Laboratories OA program, no noncon-formances or deficiencies were found in the selected areas examined.

III. Wyle Laboratories has been performing or-site inspections and refurbishments of Limitorque motor operated valves for nuclear utilities. The inspection team examined Wyle Laboratories training course outline for Limitorque trotor operated valves. Wyle Laboratories training course appeared to cover all of the major Linitorque EC issues to include wiring, T-drains, lubricants, seals and gaskets.
