JC's contribution to the nuclear industry represents appteximately seven percent (7%) of its total workload.
C.
Follow-up on 10 CFR Part 21 Report 1.
Background Information Jamesbury Corporation (JC) notified the NRC-IE Region I by letter dated March 31, 1978, of the failure of at least one of four Jamesbury Corporation 30" - 150# "N" Class 3 Wafer-sphere valves (3226EX) with Limitorque actuators (SMB-0025 H3BC) to meet the nominal closing time of 30 seconds, specified in Bechtel Corp-oration (BC) Specification 10466-M-235Q, Revision 5.
BC purchased fifty-two (52) 30" - 150#
"N" Class 3 Wafer-sphere valve with SA-515 Grade 70 bodies and SA-351 Grade CF8M wafers. Twenty-four (24) of these valves were to have actuators that would meet the following design conditions specified on BC Drawing 10466-M-235Q, Revision 5.
Required Closing Time (sec) 30 Design Temperature F 185 Design Pressure (psig) 200 Maximum Pressure Differential Across Disc (psig) 198 Maximum Torque 24,000 Ft.#
Working Fluid Raw Water Limitorque Actuator Model No.
SMB00/25/H3BC.
3 JC purchased the actuators from Limitorque Corp. (LC) in accord-ance with their drawing A-090-9000-00, Revision B, dated April 14, 1977, which specified the following:
a.
Actuator Model No. SMB00-25/H3BC b.
Mounting Position "B" c.
Degree of Rotation 90 clockwise to close d.
Speed 30 seconds e.
Torque 4400 rt. lbs.
f.
Spline adapter per Jamesbury Dwg. 078-449 g.
Current Characteristics (1) Voltage 460 ac (2) Cycles 60 l
(3) Phase 3 The valves were manufactured and hydrostaticly tested at the JC Main Plant in Worchester, Massachusetts, and four (4) valves serial numbers ND-38575-01A, B, C, and D were shipped to Union Electric Coupany (UEC),
Callaway Plant Number 1, on Jauaary 25 and 27, 1978. The BC inspec-tor issued three (3) Quality Surveillance Deficiency Reports PSQ-222 dated February 14, 24, and 28, 1978, which identified the closure time for valves serial number ND-38575-02 E, F, and G, and 38576-02 C, i
G, and H as beir-in excess of 30 seconds.
JC in their letter of March 9, 1978, informed BC that certain valves i
had incorrect vendor supplied actuator gearing. The correct gearing was obtained from LC and installed in valves serial numbers ND-38575.
02E, F, and G and retested at 100% and 80% voltage and they closed in 29 seconds.
i LC Service Personnel installed the proper actuator gearing on the valves at the UEC Callaway Plant Number I site in April 1978, and the actuator ge.. ring of the remaining valves were changed at the JC Main Plant during May 1978, and tested at 100% and 80% voltage.
All valves closed at or less than the 30 seconds specified.
2.
Objectives The objectives of this area of the inspection were to ascertain whether the eport of the incorrect valve actuator gearing was adequate, and in conformance with 10 CFR Part 21.
Alho to ascertain the generic implications of this problem, and whether the corrective action was appropriate.
4 3.
Method of Accomplishment The objectiv:s of this area of the inspection were accomplished by:
a.
Review of the following documents:
(1) BC Purchase Order 10466-M-235-2.
(2) BC Drawing Number 10466-M-235Q, Revision 5.
(3) JC Drawing Number A-090-9000-00, Revision 2, "Limitorque Actuator SMB-00/25-H3BC w/30" Wafer Sphere Valve."
(4) BC Quality Surveillance Deficiency Reports PSQ-222 dated February 14, 24, and 28, 1978.
(5) JC letter dated March 9, 1978, to Bechtel Corporation.
(6) Nuclear Products Quality Checklist.
(7) JC Inter-office Memorandum No. TGT-65 dated April 18, 1978,
Subject:
Limitorque Response Times.
(8) JC specification JSN-T32, Revision 1,
Subject:
Cycle Testing, Measurement and Recorded Data Requirements for Motor Operated Valves.
The review of the foregoing documents was to ascertain whether the 10 CFR 21 report accurately described the problem and included all pertinent information, and whether the timing of the report was consistent with the requirements.
b.
It was verified and reported in Report 99900357/79-01 that JC has posted Section 206 of PL93-438, and Engineering Procedure EP14, dated April 1,1978, establishing the rules for reporting defects that may cause a safety hazard on shipped products to nuclear plants.
Procedure EP 14 was reviewed to verify that it p~rovides for the following:
(1) Identified the JC officers that must be notified of such defects.
5 (2) Established the timing and officers responsible for report-ing such defects to the Commission.
(3) Notification of customers.
Discussions with the JC cognizant personnel concerning the cause, c.
effect, and evaluation of the safety significance of the defects.
4.
Findings From the documents reviewed and discussions with cognizant a.
personnel, the following was determined:
(1) The BC purchase order and drawing require a valve closure time of 30 seconds: however, the P0 did not define the spec-ified time as maximum, minimum, or nonimal closing time.
(2) JC interpreted the 30 second closing time to be a nominal closure time.
(3) JC in their purchase order to LC specified a " speed" of 30 seconds and did not define it as maximum, minimum or nominal closing time.
(4) LC interpreted the " speed" of 30 seconds to be a nominal closure time.
(5) The valves were not tested to confirm closure time until requested by a BC inspector.
(6) The gearing supplied by LC was not identical for all valves; therefore, the closure time varied, with some closure time requiring 37 seconds.
(7) JC does not have the facilities to perform flow tests on 30 inch valves.
(8) The gearing in the valves actuators were changed and the valves were found to close in 30 seconds or less in a no flow test.
(9) JC notified the NRC IE Resident Inspector on March 31, 1979, that at least one of the four valves shipped to Callaway, had actuator gearing characteristics which prevented it from meeting their specified closure time.
(10) It was determined that JC had reported the component failure in a timely manner and the report was factual and complete.
6 b.
No deviations or unresolved items were identified.
5.
Generic Impact JC reviewed the specified closure time on all orders for "N"
stamped valves both inhouse and shipped. A procedure was developed for orders inhouse to verify that the valves closed within the speci-fied time and requiring the results of the tests to be recorded. The Project Managers requested the customers of valves that had been shipped to evaluate the safety significance of the closure time of the valves.
D.
Exit Interview At the conclusion of the inspection on October 15, 1979, the inspec-tor met with the company's management, identified in paragraph A for the purpose of informing him as to the results of the inspection.
During this meeting management was informed no deviations or unresolved items were identified.
The company's management acknowledged the inspector's statement and had no additional comments.
