September 30, 1991 NRC INFORMATION NOTICE 91-61: PRELIMINARY RESULTS OF.VALIDATION TESTING OF
MOTOR-OPERATED VALVE DIAGNOSTIC EQUIPMENT
Addressees All holders of operating licenses or construction permits for nuclear power
reactors and motor-operated valve (MOV ) diagnostic equipment vendors-identified
herein.
Purpose The U.S. Nuclear Regulatory Commission(NRC) 'is'issuing this information notice
to alert addressees to the'preliminary: results of the validation testing of MOV
diagnostic equipment.conducted..by.the MOV .user's group (MUG) of nuclear power:
plant licensees. It is expected that recii'ents will review the information,.
for applicability to their facilities and consider actions, as appropriate, to
avoid operability problems with MOVs .
However, suggestions contained in this information notice are not NRC requirements; therefore, no-specific action or
written response is required.
_ .
Description of Circumstances '
In 1990, the MUG initiated a program to conduct tests of MOV diagnostic equip- ment to validate'the accuracy of the equipment asserted by the diagnostic
equipment vendors. .The MUG requested the Idaho National Engineering-Laboratory
(INEL) to provide a test.stand for the 'progrIam and to collect test data. The- NRC Office of..Nuclear Regulatory Research (RES .) provided funds for INEL to
participate, with the stipulation that the resu'lts'of the testing would be made
available to the NRC and the public.
.
The diagnostic equipment vendors participating in.
the MUG test program were
ASEA-Brown'Boveri (ABB ) Impell, ITI-MOVATS, Liberty Technologies, Siemens/KWU,
Teledyne, and Wyle Laboratories.
The INEL test'stand included a Limitorque motor operator which drives a valve
stem into a water reservoir with a compressed air overcharge.
INEL obtained accurate measurements of actuator torque and'tthrust using a torque arm and a
stem-mounted load cell, respectively. Each diagnostic equipment vendor
installed and operated its own equipment to obtain measurements of torque , thrust, and various other parameters.
Several diagnostic system vendors did not meet all of their stated claims of
accuracy. Differences in the time response of the INEL test stand equipment
dia nostic systems being tested may have contributed to deviations in
0924O24 Z
IN 91-61 September 30, 1991 the observed thrust measurements.
Further, some of the diagnostic equipment exhibited problems and anomalies, such as failed sensors or difficulties in
calibration, during the testing program. Of particular concern to the NRC is
that these time inaccuracies, problems, and anomalies may not have been
detected during normal use of the diagnostic equipment at a nuclear facility.
The MUG is comparing the data collected by INEL with the data collected by each
of the diagnostic equipment vendors.
At a meeting in Richmond, Virginia , on July 30, 1991, the MUG released a progress report of the validation
testing.
The NRC has placed this report, "MOV User's Group - Progress Report
of the Validation Committee," in the NRC Public Document Room (PDR ),
2120 L Street, N.W., Washington , D.C. 20555 (telephone (202) 634-3273).
The
MUG is continuing to review the test data and intends to release a final report
in January 1992. The NRC will place the final MUG report in the PDR .
During its July meeting, the MUG stated that licensees and diagnostic equipment
vendors should review the progress report for its applicability to the MOVs
installed in nuclear power plants.
The MUG also alerted licensees and diagnos- tic equipment vendors to their responsibilities under "Reporting of Defects and
Noncompliance," Part 21 of Title 10 of the Code of Federal Regulations.
Discussion of Safety Significance In NRC Bulletin 85-O37"'Rot6fr-Operated Valve Common Mode-F-ai flres During Plant
Transients Due to Improper Switch Settings," and its supplement, the NRC
recommended that licensees develop and implement a program to ensure that
motor-operator switch settings for MOVs in several specified systems are
selected, set, and maintained so that the MOYs will operate under design-basis
conditions for the life of the plant.
In NRC Generic Letter 89-10 ,
"Safety-Related Motor-Operated Valve Testing and Surveillance," and its supple- ments, the NRC recommended that the program to verify switch settings be
extended to ensure MOVs .operate properly in all safety-related fluid systems.
To meet the recommendations of the bulletin and the generic letter, licensees
have placed increasing reliance on diagnostic equipment to set the motor
operator switches and to ensure the operability of MOVs . The accuracy of the
diagnostic equipment has a direct impact on the operability of entire safety
systems because the same diagnostic equipment is generally used to set the
motor operator switches of the valves in all trains of a safety system.
This concern for the effect that the use of diagnostic equipment can have on
overall system operability prompted NRC to participate in the MUG validation
testing.
The NRC will continue to monitor the activities of licensees and
diagnostic equipment vendors in evaluating the results of the MUG test program.
