s Reply to Non-Cited Violation 50-341/93003 dated March 30, 1993
Statement of Non-Cited Violation:
i 10 CFR Part 50, Appendix B, Criterion II, " Test Control," requires
!
licensees to evaluate the results of tests to assure that test
'
requirements have been satisfied. Failure to promptly evaluate j
results from NOV dynamic testing performed as part of its commitment
,to Gsneric Letter 89-10 is considered a violation of Criterion.II.
]
However, the NRC wants to encourage and support licensee's initiatives
- '
for self-identification and ' correction of the problems.- Berefore,
'
this violation is not being cited because the criteria specified in Section VII.B.2 of the " General Statement of Policy and Procedures for i
NRC Enforcement Action," (Enforcement Policy, 10 CFR Part 2, Appendix C) were satisfied. Specifically, the licensee identified
.
that thorough test result evaluations were not completed at the time
~
of the dp tests and subsequently developed a "HOV Post-testing Review" evaluation form to review the results. ~The licensee committed to complete an evaluation form for the 21 previously performed dp tests
}
by May 14, 1993, and to include consideration of motor capability.
In i
addition, plant, procedures were revised to require prompt evaluation
following future dp tests.
i Include in your response:
(1) the revised acceptance criteria for MOV
- !
tests, including consideration of actuator motor capability, and (2)
[
the results of the reevaluation of the MOV tests evaluated using the-
,
previous unacceptable criteria.
]
Detroit Edison Response:
!
i (1) Revised Acceptance Criteria for MOV Tests l
.
's As committed during the Phase II Inspection, Detroit Edison will use thrust reduction margin for the rate of loading, stem lube degradation
and torque switch repeatability effects along with the diagnostic i
equipment accuracy. 'Ihe revised thrust acceptance criteria being used-(
o during the static as well as dynamic test evaluation process is j
already included as Attachment 4 to procedure 47 306.02 "v0TES System Operating Procedure" (see attachments). A copy of the revised procedure 47 306.02 was sent to NRC Region III the last week of-.
i February 1993 MOV Program Guideline Attachment 11 (see attachments)
I was revised to account for reduction in the thrust margin due to above i
mentioned effects per the industry adopted' methodology. Bis revised
'
thrust acceptance criteria was used for evaluation of dynamic test results. Procedure'47 306.02 Attachment 4 will be-further revised
.l prior to the next MOV test to better coordinate with the revisions to
,
'
the MOV Program Guideline Attachment 11.
Procedure 47 306.02 requires completion of the evaluation of dynamic and static test results prior
.
i

to processing the work package through the Nuclear Shift Supervisor for returning the MOV to service.
Detroit Edison is considering the use of a statistical scandard deviations approach in combining the thrust reduction effects due to rate of loading and sten lube degradation. Until plant specific parameters for rate of loading and stem lube degradation can be established by additional dp testing, industry provided data will be utilized. Therefore, Attachment 4 to Procedure 47 306.02 may be
'
revised if the statistical approach is acceptable based on further dynamic testing performed at Fermi 2.
Detroit Edison presently evaluates the actuator motor capability during the diagnostic testing based on 60% locked rotor seating current (LRA) for safety related HOVs except a for few HOVs where the seating current criteria is lower than 60% LRA. This criteria is included in the procedure 47 306.02, " VOTES System Operating Procedure".
In response to the NRC Inspector's concern for unseating motor current during the opening stroke for gate valves, procedure 47 306.02 was revised to include the 60% LRA for maximum unseating motor current. During the design basis review, the actuator motor
,
capability at degraded voltage is evaluated per the Limitorque SEL
methodology which verifies the motor torque output meets the design required torque and provides the maximum allowable torque switch setting based on the spring pack curve. However, due to variation in the spring pack stiffness and stem factor, the motor capability during the diagnostic testing could not accurately be predicted by torque switch setting and measured thrust. Therefore, Detroit Edison feels confident that the motor capability evaluation based on its operating parameter (i.e., motor current) during the diagnostic testing is a more accurate performance indicator.
(2) Results of Re-evaluation of the MOV Tests
.
Based on the revised acceptance criteria for HOV tests describe'd
!
above, as committed during the Phase II Inspection, Detroit Edison evaluated the dynamic test results of 21 MOVs. The evaluation included the review of the differential pressure acting on the HOV and the calculation of rate of loading and valve factor for those cases during which acceptable differential pressure (dp) compared to the design basis dp was available during testing. The summary of evaluation is as follows:
The differential pressure (dp) achieved during the dynamic testing for 9 HOVs was between 77 and 100% of the design dp.
The valve factors and rate of loading results obtained from the evaluation were considered along with the stem lube degradation, torque switch repeatability and equipment accuracy for predicting thrust margin as well as HOV capability at the design basis differential pressure. The rate of loading effects varied from 15 to 32%. The valve factors at flow cut off for globe valves were lower than those used in the design
!
<

Enclosure to NRC-93-0052
Page 3
,
basis review and for gate valves were higher than those used in the design basis review. However, these HOVs are considered operable based on the available and required thrust at the revised valve factors based on the dynamic testing. As part of the MOV evaluation process, Deviation Event Reports (DER) were issued due to marginally meeting the acceptance test criteria or exceeding the presently available maximum structural strength limits for valves and actuators. Based on HOV operating history and the range of over thrust, these valves are considered acceptable. Issuance of the DERs will ensure further evaluation and follow-up corrective action are performed in a timely manner.
Five HOVs did not cxperience adequate differential pressure during the dynamic testing due to inadequate system lineup configuration. The inadequate differential pressure was due to the pressure effects from interconnected piping not properly isolated from the test loop. Four of these HOVs are minimum flow HOVs for pulps and need to be retested such that there is no pressure effect on the downstream side due to flow in other connected piping system. These HOVs will be scheduled for re-testing during or prior to the fourth refueling outage scheduled to start in March 1994. The dynamic test results (VOTES thrust signature) for one more MOV could not be evaluated due to a high calibration error for extrapolation. The design basis
differential pressure for this HOV is only 15 psid and therefore the HOV will not be retested under dynamic conditions. These HOVs have
<
'
been tested in the static condition and do have adequate thrust margin for performing their safety functions. This. conclusion is based on the static test results of an additional 59 HOVs tested at Fermi 2.
Six HOVs in Residual Heat Removal (RHR) service water system were
tested undar normal service water system operating configuration.
These HOVs are located at the discharge end of the system. Due to
substantial pressure drop throughout the system, differential pressure experienced by these HOVs was around 6 psig and therefore, the flow
'
cut off points on the thrust signature could not be clearly differentiated. These HOVs were only dynamically tested and as-left thrust values were equal to or above the target thrust at design basis dp of 135 psig. The design basis differential pressure (dp) and target thrust are based on the mispositioning scenario which considered the pumps deadheading and no system pressure drop is occurring. Supplement 4 to G.L. 89-10 exempts BWR plants from consideration of the mispositioning scenario. Detroit Edison elected to consider the mispositioning scenario during the design basis for conservative Maximum Expected Differential Pressure (MEDP) and corresponding thrust requirements but did not dynamically test these HOVs under the mispositioning scenario. The HOVs stroked (open/close)
during the dynamic testing with as-left thrust higher than the minimum design required thrust corresponding to MEDP. These valves are considered operable and capable of performing the safety function.
Therefore, no further testing will be performed for these six HOVs.

1.0 PURPOSE This procedure provides instructions for the Static or Dynamic testing of motor-operated valves (fADVs) using Liberty Technology's Valve Operation Test and Evaluation System (VOTES). This procedure is to be followed in order to comply with the requirements of NRC Geneeric tetter 89-10 to verify, trend and track MOV performance and/or ability to perform its intended safety function.
NOTE:
As a matter of practice, the first *as left" test on a valve is considered the baseline test. Each subsequent test is compared to the baseline test for trending and evaluation. A new baseline test should be performed as soon as possible after any major work which may be done on the valve or operator which may change the valve's baseline characteristics. This may include but is not limited to: valve disassembly, reseating, repacking, stem replacement, MOV gear, bearing, bearing housing gaskets, torque switch or stem nut replacements.
2.0 PRECAUTIONS AND 1.lMITATIONS 2.1 Review applicab!e Radiation Work Permit (RWP) for requirements in the work area.
2.2 Do not allow the entry of foreign materials into working parts of the valve operator.
2.3 Only individuals that have completed VOTES Training / Certification or individuals under the direct supervision of qualified personnel may operate the VOTES equipment.
2.4 Only individuals that have completed VOTES Signature Analysis or MOVATS Signature Analysis training may perform Signature Analysis for purposes of completing the Degradation Data Sheet, Attachment 2.
.
2.5 Ensure all power connections to VOTES System are 120Vac,60 Hz.
-
2.6 Ensure the VOTES System is deenergized while installing test equipment, associated sensors and wirmg connectors to prevent voltage / current spikes from damaging the computer / test equipment.
.
2.7 Do not operate computer in area where ambient temperature is less than 50 F or
greater than 104 F.
i 2.8 When a problem or nonconformance is noted, work shall stop if the testing is detrimental to the valve or system. Notify the NSS to ensure that required
,
deficiencies are resolved before a valve is returned to service. All deficiencies noted shall be listed on the Work Request as appropriate.
2.9 If there must be jumpers installed or wires lifted to stroke valve, the use of an Interim Alteration Checklist is required.
2.10 As-Found signatures should be acquired before altering setting >f torque switch or
limit switches.
2.11 Electrical circuits associated with MOVs cannot be isolated during certain plant i
conditions. These must be identified prior to work.

2.12.2 Use of excessive force on the declutch lever when engaging into manual drive mode.
2.12.3 Use of excessive force on the declutch lever in attempt to return the actuator to the electrical operation position. Internal damage is possible.
2.12.4 Use of unauthorized mechanical lever on the handwheel to seat or unseat the valve could cause damage to actuator and valve.
'
2.13 The sequence and method of testing may be repeated or altered at the discretion of the Test Leader to ensure complete data acquisition for subsequent signature analysis. Re-tests may be performed under this procedure provided the tests are sequentially numbered and each is documented on a separate consecutively numbered Test Data Sheet, Attachment 1.
.
2.14 If during performance of this procedure, it is discovered that actuator rework is required, it should be done in accordance with Procedure 35.306.006, Enclosure C.
j 2.15 11 during performance of this procedure,it is discovered that the' VOTES Force Sensor
}
is not properly attached to the valve yoke (e 9. not preloaded), it shall be removed l
and a new sensor installed per 35.LitA 009.
2.16 Any discrepancies noted during the conduct of this procedure must be reported to
'
the appropriate Supervisor for disposition.

2.24 ff the maximum values as contained in the test data sheet are exceeded, the valve shall be declared inoperable either until the valve is adjusted within the limits or Nuclear Engineering analyzes and accepts the out of specification condition'.
'
2.25 An *as found* LLRT should be performed prior to any adjustments, repair, or enhancements to the valve, packing gland, stem or operator. This includes but is not limited to stem lubrication or nut tightening.
2.26 in some cases, to perform a sensor calibration,it may be necessary to loosen and remove the packing gland nuts or follower to prevent calibrator clamp interference.
The performance of this on an LLRT valve will inop the valve and invalidate the valve's LLRT results. Ensure the Test Supervisor is notified PRIOR TO loosening the gland nuts to assure that the *as found* LLRT results are not jeopardized and that a
- post * LLRT can be performed immediately after the thrust test.
2.27 Peak motor seating current should not exceed 60% of locked rotor amps (LRA) on safety related MOVs. This value is the * Rule of Thumb * and if exceeded, must be evaluated in the Degradation Data Sheet, Attachment 2. Exceptions to this * Rule of Thumb * are listed in Seating Current Capacity Exceptions, Enclosure D.

5.4 Calibrating the VOTES Force Sensor r
,
..
.
I NOTE (1):
The calibration procedure must be performed at least twice for every l
sensor mounted on a valve yoke. The calibration procedure should be l'
repeated if the close torque switch setting has been changed by '
greater than one (e.g. from 2-1/2 to 1-1/2), if the actuator body or valve has been physically altered, a new VOTES sensor installed, or a new stem has been installed.
I
!
NOTE (2):
in some cases, to perform a sensor cahbration it may be necessary to loosen and remove the packing gland nuts or follower to prevent calibrator clamp interference. The performance of this on an LLRT valve will inop the valve and invahdate the valve's LLRT results.
-
Ensure the Test Supervisor is notified PRIOR TO loosening the gland
nuts to assure that the *as found" LLRT results are not leopardized anct that a * post * LLRT can be performed immediately after the thrust
'
test.

For the calibration to be acceptable the CFA must be between.970 and 1.00. if _ CFA is within that acceptance criteria then the value of i
RSQ is meaningless. If true zero value had not been identified (or
,
marked) then an fuA will appear after CFA. which makes an RSO value (
the determining factor for meeting the.970 - 100 acceptance criteria.
in that case it is also highly desirable to make every effort to obtain
an RSO of at least >.997, so that system accuracy is not degraded.

If the values are acceptable save the calibration to the hard disk then repeat the calibration to verify that the two slope values (BFSL sens)

are within 5% of each other. Record the applicable values on the test

data sheet. If the second calibration had a better CFA (or RSO) then save it to the herd disk. which overwrites the first cal. If the first cal i
