REPORT FOR LIPERICK GENERATING STATION UNIT 1 IN RESPONSE TO I.E. BULLETIN 85-03 PURPOSE _

This report responds to I.E. Bulletin 85-03 which required licensees to develop and irrelement a program to assure that motor-operated valve (MOV) switch settings In certain safety systems are selected, set and maintained correctly such that the MOVs will function during This both report normal and abnormal events within the plant design basis.is in 1.E. Bulletin 85-03 action item (f) for Limerick Unit 1.

RESPONSE TO BULLETIN REOUTREMENTS The following discussion provides PECo's respenses to items (a) through (f) of I.E. Bulletin 85-03 The recuirements of the Bulletin are restated belcw along with PEco's response.

y Item (a)

"Review and doctrnent the design basis for the operatico of each valve. This doctanentation should include the maximtsn differential pressure expected during both opening an these valve operations and events are included in the existing, approved design basts, (i.e., the design basis docunented in When pertinent IIcensee submittals such as FSAR analyses a determining the maxirn.rn differential pressure, those single equipment failures and inadvertent eculgrnent operations (such as inadvertent valves closures or openings) that are within the plant design basis shN1d be asstrned."

PECo Resoonse Reference (3) provided PECo's preliminary I.E.The Bulletin 85-03 Information l

submittal which addressed bulletin action item a). ik supplied b with this action item and describes hcw it relates to the overall L progran.

PECo was a participating merrber of the BWROG ccmnittee which established the scope of systems and valves subject to the I.E. Bulletin This ccmnittee also developed and recemnended the 85-03 recuirements.

' rrethodology by which the MOV design basis operational differentialRef pressures were to be calculated. report whichPECo describes has adoptedthese results a regarding I.E. Bulletin 85-03 program Irnolementation. ld the BWROG Ccmnittee's reccmnended program end has expanded it to inc u e other Motor Operated Valves.

For Limerick Units 1 and 2, the systems identified by the BWROG as being subject to I.E. Bulletin 85-03 are the High Pressure Coolant injection CHPCI) and Reactor Core isolation Cooling (RCIC) Systems.

The BWROG report further defined the Bulletin scope by stating that*

only those HPCI/RCIC MOVs designated as having an active safety function need ccumiy. For the other safety-related MOVs which the BWROG classifled as having no active safety ftnction, slmllarly developed methodologies were used to calculate their maxinun operational differential pressures. These calculations are considered conservative, since they include a conservatively nodeled hydrodynamic pressure ccrrponent.

The NRC in Reference (4) took exception with the BWROG position on I.E. Bulletin 85-03 The central issue concerned the exclusion of certain MOVs frcm the scope of the Bulletin on the basis that they would not be inadvertently out of pos! tion when called upon to operate.

Inadvertent M3V operation according to the BWROG ls beyond design basis and failures resulting frcm it are considered within system single failure criteria. Since PECo's !.E. Bulletin 85-03 program scope includes all HPCI and RCIC safety-related MOVs, the NRC's major objection '

with the BWROG is not applicable to Limerick.

The attached Tables 1 and 2 present a stirmary of information, Including differential pressure recuirements, appilcable to the valves /

l

' operators in the HPCI/RCIC systems. These tables have been formulated to provide sufficient technical data to permit identification of rrotor-operated valve assentiles for which similarity (type) testing can be applied. In these tables please note the changes In the The differential pressure values previously reported in Reference 3).

a negligible effect on MOV operating requirements as will be dertonstrated in later discussions.

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, torque bypass, position !!mit, overload) for each valve operatton (opening and closing).

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

PECo Response Reference (3) provided a brief swmary of the Limerick program The elements that support ccrno11ance with this action item.

values remained as the bases for setting the torque switches on those valves where the values exceeded the newly calculated design basis differential pressures. Therefore, this Limerick program feature provides additional conservatism with respect to valve capablitty to fmetion under higher than the design basis differential pressure cond!tIons.

• With other valves for which the original specified differential pressures were less than the newly calculated values , the as-left settings were confirmed to be adecuate to assure MOV closure To ensure against the higher design basis differential pressures.

l - that replacement valves are capable of operating against the l

I higher design basis differential pressures, the appilcable Limerick valve specifications are being revised to reflect the more stringent design requirements.

The necessary specification revisions are scheduled to be completea by the end of 1987.

Toroue Switches f

I At Limerick Generating Station, notor-operator torque switches settings are based on the following criteria:

l 1)

The mininun acceptable setting shall be such that the developed stem thrust, asessured using the Motor Operated Valve Analysis and Test System (MOVATS), is sufficient to fully close the valve against the as-specified differential pressure.

2)

The maxinun acceptable setting Is constrained by the twer of ths fo11 ming four limits:

a)

The valve maxinun a11mable thrust as specified by the l

' valve manufacturer.

I b) The maxinun allowable thrust for the specific noter operator type.

' c) The maximun torcue capab!11ty of the rrotor @ degraded voltage, d) Spring pack specific maxinun a11mable settings.

Thermal Overloads At Limerick Generating Station, safety-related trotor-operator thermal overload (TOL) protection has the following features:

(1) Motor-operator overload trips are annunciated in the Control rocyn.

(2) The motor-operator overload trip is bypassed during autcractuations which increases the probability that the valve will perform its safety function.

(3) Thermal overload protection can be bypassed In an emergency This is accortplished by holding by the control rocm operator.

(4) The overload heaters are sized in accordance with the special service requiremr.nts of intermittent duty motors.

The sizing criteria is such that the trotor will rapidly trip off If a locked rotor condition exists; but provides sufficient margin over nortnal operational loadings.

The cuerload heaters on all I.E. Bulletin 85-03 MOVs were verlfled to be properly sized and oriented during Limerick's first refuel outage.

Tables 5 and 6 provide details of the specific supplementary tests performed.

In conclusion, PECo's Limerick I.E. Bulletin 85-03 program provides a very high confidence that the subject MOVs will perforTn their design basis safety fmet ton.

Item (d)

"Prepare or revise procedures to ensure that correct switch settings are determined and maintained throughout the life of the plant. Ensure that applicable Industry recernnendations are considered in the preparation of these procedures."

PECo Response Procedures E11.10, FE-1f+ and FE-16 iswere used used durin used as recuired. Limerick Maintenance Procedure PMQ-500-087 to ensure that the correct trotor-operator switch settings are maintained in addition to providing an electrical checkout follcwing maintenance.

This procedure is performed following safety-related MOV maintenance tb to provide a cerrolete functional checkout of the trotor-operator, revisions to the above procedures were determined to be necessary.

As part of the procedures review, PEco developed a specific MOV maintenance Under the PEco program, all future MCV maintenance MOVATS results.

will be reviewed against this list to determine what testing nust be perforTned prior to returning any safety-related MOV to service.

Item (e)

"Within 180 days of the date of this bullettn, submit a written (1) repo report to the NRC that:

Actual thrust as obtained fran motor operated valve analysis and testing syston measuranents (FKNATS).

5) value is torque (in--lbs), actual torque ' as confinned by testing of similar units.

6)

Actual thrust of 1300 lbs is acceptable since design thrust for dp of 50 psi is 1032 lbs per hientical valve llV-49-IF084, Mien interpolated to 59 psi thrustAlternativ required is 1071 lbs.
