IE BULLETIN 85 MOTOR-OPERATED VALVE COMMUN MODE FAILURES OURING PLANT TRANSIENTS DUE TO IMPROPER SWITCH SETTINGS e

WRITTEN REPORT 1 REQUESTED UNDER ITEM F, IEB 85-03 FOR ARKANSAS POWER.AND LIGHT COMPANY ARKANSAS NUCLEAR ONE

UNITS - 1 AND 2 f

4 FEBRUARY, 1988 L ...

t

. RESPONSE TO IE BULLETIN 85-03 ARKANSAS NUCLEAR ONE, UNITS 1 AND 2 IE Bulletin 85-03 (9CNA118511) requested Arkansas Power and Light to implement a program to ensure that switch settings on high pressure safety injection and auxiliary feedwater system safety-related motor-operated valves (MOV's) are selected, set, and maintained correctly to accommodate the maximum differential pressures expected on these valves during both normal and abnormal events within the design basis. Provided below is the response for Arkansas Nuclear One, Units 1 and 2.

Action Item "a" "Review ard document the design basis for the operation of each valve. This documentation should include the maximum differential pressure expected during both opening and closing the valve for both normal and abnormal events to the extent that these valve operations and events are included in the existing, approved design basis, (i.e., the design basis documented in pertinent licensee submittals such as FSAR analyses and fully-approved operating and emergency procedures, etc.). When determining the maximum differential pressure, those single equipment failures and inadvertent equipment operations (such as inadvertent valve closures or openings) that are within the plant design basis should be assumed."

Response

Arkansas Power and Light has conducted the requested reviews for both Units 1 and 2 with these results documented in the attached "MOV Data Summary" Tables. These results were initially transmitted to the NRC by letter dated May 14, 1986 (OCAN058503),

as required by IE Bulletin 85-03.

Action Item "b" "Using the results from item "a" above, establish the correct switch settings. This shall include a program to review and revise, as necessary, the methods for selecting and setting all switches (i.e., torque bypass, position limit, overload) for each valve operation (opening and closing).

If the licensee determines that a valve is inoperable, the licensee shall also make an appropriate justification for continued operation in accordance with the applicable technical specification."

Response

Arkansas Power and Light has implemented a program to review and revise, as necessary, the methods for selecting and implementing o

. Response (cont.)

switch settings. These activities for the 85-03 Bulletin MOV's >

and the additional MOV's that were tested, were performed under a special work plan that was utilized for MOV testing and other MOP related inspections. MOVATS (Motor Operated Valve Analysis and Testing System) was utilized to accurately set switches based on the desired thrust values and switch trip points, as described in our letter to the NRC dated October 1, 1986 (9CAN198692).

In accordance with IE Bulletin 85-03, existing switch settings were reviewed for operability with regard to the design differential pressures imposed by IE Bulletin 85-03 and these results are shown in the attached "MOV Data Summary" Tables in the "As Found Valve Operability" column. This review of "As Found Operability" concentrates on the individual actuator travel in both directions by examining the torque switch bypass, undervoltage requirerents, the as-found torque switch trip (TST) and the minimum setting limits derived from the valve and actuator calculations. The end results of this review was the designation of each MOV as either "operable", "inoperable" or if it could not be determined, "indeterminate". For those designated "indeterminate", each MOV was not considered inoperable based on the high probability that it would have performed its function due to the conservatism in the calculations. These operability classifications deal only with the operability of the MOV (As Found) in the direction given and are not comparable to "operability" as defined by the Technical Specifications.

Operability evaluations of the MOV in accordance with the applicable Technical Specifications were performed at the time of the diagnostic testing (H0 VATS) to determine the reportability of l any inoperable MOV's. These evaluations were performed considering the safety function of the MOV, the requirements of the system containing the MOV, and previous operating and testing performance. As a result of these evaluations, no reportable items per 10CFR50.72 and 10CFR50.73 were found during the Unit 1 and 2 MOV testing.

, Action Item "c" "Individual valve settings shall be changed, as appropriate, to those established in item "b", above. Whether the valve setting is changed or not, the valve will be demonstrated to be operable by testing the valve at the maximum differential pressure determined in item "a" above with the exception that testing motor-operated valves under conditions simulating a break in the line containing the valve is not required. Otherwise, justification should be provided for any cases where testing with u-

, Action Item "c" (cont.)

the maximum differentialspressure cannot practicably be performed.

This justification should include the alternative to maximum differential pressure testing which will be used to verify the correct settings.

Note: This bulletin is not intended to establish a requirement for valve testing for the condition simulating a break in the line containing the valve. However, to the extent that such valve operation is relied upon in the design basis, a break in the line containing the valve should be considered in the analyses prescribed in items "a" and "b" above. The resulting switch settings for pipe break conditions should be verified, to the extent practical, by the same methods that would be used to verify ,

other settings (if any) that are not tested at the maximum A

differential pressure.

Each valve shall.be stroke. tested, to the extent practical, to T verify that 'the settdngs defined in item "b" above have been properly implemented even if testing with differential pressure cannot be performed".

Response

(

Each MOV tested in accordance with I.E. Bulletin 85-03 was tested to verify that the settings defined in Action Item "b" were properly implemented and the MOV functions properly at these settings. The "Test Method Description / Justification" column in the attached "MOV Data Summary" Tables describe what testing was performed on each MOV.

Differential pressure (DP) testing was performed on selected valves representing valve groups that encompass all the I.E.

Bulletin 85-03 valves. Differential pressure testing was performed on 17 MOV's in ANO Unit 1 and 16 MOV's in Unit 2. Most of the MOV's were DP tested close to their design DP from the results of Action Item "a". In cases where the maximum DP could not be obtained, the valve stem thrust recorded at the test pressure was extrapolated up to the design DP. The method used to extrapolate valve stem thrust was a simple ratio of the design to test pressures multiplied by the test thrust. This extrapolation y method was described in our response to additional questions in '

our letter dated October 6, 1987 -(1CAN108703).

n 1

Though the DP testing performed was considered sufficient in most ,

respects, not all valve types were tested. Explanations are provided in the attached "MOV Data Suinmary" Tables for valves that \

could not be DP tested.

, Response (cont.) ac ,

Evaluation of the results of DP testing provided confidence that the' calculations utilized to predict the performance of the M0V's are conservative and can be used to set torque switches on other-MOV's at ANO using MOVATS equipment and procedures.

This item is intended to be completely consistent with action item g' ' ' 3.2, "Post-Maintenance Testing (All Other Safety-Related Components)," of Generic Letter 83-28, "Required Actions Based on i

Generic Implications of Salem ATWS Events." These procedures I,

should include provisions to monitor valve performance to ensure

- if the torque or torque bypass switch setting har been

(' significantly raised above that required."
