i PEACH BOTTOM ATOMIC POWER STATION RESPONSE TO I.E. BULLETIN 85-03 PURPOSE This report responds to I.E.Bulletin 85-03 which required licensees to develop and invloment a program' to hssure that motor-operated valve (MOV) switch settings in certain safety systems are selected, set and maintained correctly such that the MOVs will function during both normal and abnorTnal events within the plant design basis. This report is-Intended to partially satisfy the program conpletion reporting requirements of I.E.Bulletin 85-03 action item (f) for Peach Bottan Units 2 S 3.
Although the program described herein is applicable to both Peach Bottcm Units, the specific test and. Inspection results apply to Unit 2 only.- The Unit 3 workscope is in progress and will be addressed upon ccmpletion.
Reportability of any identified problem or defect will be reviewed in accordance with either 10CFR21 or 10CFR50.73 and addressed separately.

stermut locknut staking 5)
As-left thrust signature testing to set torque switches and estabilsh an acceptable setting range.
6)
Instrunented differential pressure testing ~ on a representative sanple of MOVs (Unit 2 Only). This testing wl11 provide a correlation between MOV stem thrust and. valve operating differential pressure. These results will be used to validate MOVATS testing as a method for establishing proper torque switch settings.
The following discusses how these activities satisfy the required bulletin action items.
In addition, the "to-date" results of the program are discussed along with plans for future work.
. RESPONSE TO BULLETIN REOUIREMENTS The following provides PECo's responses to items (a) through (f) of I.E.Bulletin 85-03.
Each Bulletin item is restated followed by the PECo respcnse.
Item (a)
"Review and docunent thi design basis for the operation of each valve. This docunentatim should include the maximun differential pressure expected during both opening and closing the valve for both nonnal and abnonnal events to the-extent that these valve operations and events are included in the existing, approved design basis, (i.e.~,
the design basis docunented in pertinent Ilcensee sutmittals such as FSAR analyses and fully-approved operating and emergency procedures, etc.).
When detennining the maximun 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 assuned."
PECo Response Reference (3) provided PECo's preliminary I.E.Bulletin 85-03 submittal which addressed bulletin action item a).
The infonnation below provides a more complete discussion of PECo's ccmpIlance with this action item and describes how the Infonnation is related to the overall Peach Bottcxn progran.
L l
l t
F,
.. PECo was a participating member of _ the BWROG ccnmittee which established the scope of. systems and valves subject to the I.E.
iBu11etin 85-03 requirements.
This conmittee also developed the methodology by which the MOV design basis operational
-differential pressures were to be calculated.
Reference (2) is the BWROG topical report which describes these results and provides reccomendations regarding I.E.Bulletin 85-03 progran inplementation.
For Peach Bottom Units 2 and 3, the systems identified by the BWROG as being subject to I.E.Bulletin 85-03 are the High Pressure Coolant Injection (HPCI) 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 comply.
PECo has adopted the BWROG Ccrrmittee's recenmended program but has expanded it to include all HPCI and RCIC safety-related motor-operated valves." Methodologies similar to those developed by the BWROG were used to calculate the maxinun operational differential pressures for the additional MOVs. These methodologies are considered conservative, since they include a conservatively rrodeled hydrodynamic pressure conponent
("waterhactmer") which as an Industry practice has not been considered when calculating valve closing differential pressure.
Table 1 presents a 'sunrary of the calculated differential pressure requirements and other pertinent Information appilcable to the MOVs'in the HPCI and RCIC systems.
For conservatism, the calculated differential pressures correspond to the higher of the "open" or "close" design basis differential pressures previously submitted via Reference (3). Please note that there are several changes to the calculated differential pressures frcm those submitted earlier.
The changes resulted from the application of a more conservative methodology in calculating the hydrodynamic pressure ccuponent of the valve closing differential pressures. The resulting increases In required operator capacity are within the capabillties of the affected MOV assemblies.
Since all HPCI and RCIC safety-related MOVs are included in the program and their respective design basis differential pressures were based on the higher of the "open" or "close" values, we believe we have satisfactorily addressed the NRC's concern with regard to operability of valves inadvertently out of position.
" - The RCIC Turbine Trip & Throttle Valve (M0-4487 (Unit 2) S MO-5487 (Unit 3)) Is not considered to have a safety-related motor-operator since the operator is used only to open the valve Creset function) under no differential pressure. The valve's safety function to close is acccmpiished by a spring rnechanIsm.
_4 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 limit, overload) for each valve operation Copening and closing).
"If the llcensee determines that a valve is inoperable, the licensee shall also make an appropriate Justification for continued operation in accordance with the appilcable technical spec 1fIcatlon."
PECo Response Reference (3) provided a brlef sunnary of the Peach Bottcm MOV switch setting program in place at the time the bulletin was issued.
The. Information below provides details of the program aspects which were developed since then to denenstrate ccrrpliance with this action item.
General PECo has assessed the design adequacy of all those motor-operated valves which were identified in Reference (3). This assessment included the following steps for each MOV:
- 1) calculation of the minimum valve stem thrust and motor-operator torque necessary to operate the valve against maximun design basis differential pressure; 2) determination of the maximun allowable thrust and torque to which the MOV asserrbly could be subjected; 3) determination of the reconmended torque switch settings based on the minimun and maximun criteria established in steps 1) & 2) above; and 4) review of the valve and motor-operator design capacities relative to the design basis operation requirements.
Both the valve and trotor-operator manufacturers were consulted in making these determinations for all affected valves. A sunnary of this information is shcwn in Table 1.
Conclusion Through the MOV design adequacy review described above, it has been detennined that all of the HPCI and RCIC System notor-operated valves which are in-service at Peach Bottom were adequately l
sized and have the capabilltles to function as required under design basis conditions.
l l
l l
. Torque Swltches The program developed at Peach Bottom in response to I.E.
. Bulletin 85-03_ requires that motor-operator torque switches be set in accordance with the following criteria:
1)
The minimtm acceptable setting shall be such that the developed stem thrust at torque switch trip-Is sufficient to fully close the valve against the design basis differential pressure. Once the notor is de-energized, motor-operator inertia provides thrust margin over the minimtm requirement.
PECo's program does not take credit for this additional thrust corponent.
2)
The maximtm acceptable setting is constrained by the lowest of the following four limits; a)
The maximtm allowable thrust for the valve as specified by the valve manufacturer.
b)
The maximtm allowable thrust for the motor-operator as specified by the operator manufacturer.
c)
The maximtm torque capability of the notor at -degraded
- voltage, d)
Spring pack specific maximtm allowable settings.
The Peach Bottan Program requires that a MOV torque switch first be balanced and then adjusted to equal open and close settings.
Balancing adjusts the torque switch such that It operates at equal spring pack compression in both directions. Because spring pack compression is proportional to stem force, this assures that a stem force at least equal to that required to fully close the valve against maximtm differential pressure is available to fully open the valve when actuated. This is a program conservatism which further assures recovery fran inadvertent valve operatlon.
Since SMB-000 torque switches maynot be acceptably balanced the open and closure setpoints are individually verified.
The Peach Bottom Progrrm also requires that torque switch setting adjustments be made in discrete increments. The minimtm setpoint is at the next higher acceptable incremental dial setting determined by criteria 1) above to assure the minimtm closing thrust is exceeded.
In a similar fashion, the maximtm setpoint is at the next lower acceptable incremontal dial setting determined by criteria 2) to assure the maximtm thrust ilmit is not exceeded.
Therefore, this methodology provides inherent margin at both ends of the torque switch setting range. For SMB-000 type operators, the torque switch minimtm increment is 1/2; whereas, on SMB-00 and larger types the minimtm increment is 1/4.
[
Where permitted by the acceptance criteria, a torque switch setting: range.Is established during the "as-left" testing.
This information is entered onto a controlled drawing for future reference. Torque switch limiter block plates are being installed to prevent Inadvertent swltch oversetting.
Limit Switches As part of the PBAPS I.E.Bulletin 85-03 program, a special procedure (Reference 6) was developed to verify and, if necessary, reset motor-operator Ilmit switch settings.
In sunnary, this procedure requires that:
(1) the open torque switch bypass switch (i.e. on the same rotor as the close Ilmit-Indication) is to remain closed until the valve disk has unseated as evidenced by visually observing torque switch operation, noting change. In motor loading, etc.; and (2) the open Ilmit switch is set such that the stem or disk does not coast into the backseat after electrical operation is terminated.
Normal practice for SMB-000 operators ls to set.
~
the valves to stop 1/2 to I handwheel turn frcm the backseat.
For all other rising stem operators, normal practice is 1/4" to 1/2" of stem travel off the backseat.
This special procedure is in conformance with existing maintenance procedure M-9.1.
Thermal Overloads At Peach Bottom, safety-related notor-operator thermal overload (TOL) protection has the following features:
(1) Motor-operator thermal overload (TOL) device trips are annunciated in the control rocm.
(2) Auto-actuation signals bypass the overload trip circuitry, preventing the TOL frcm de-energizing the operator motor.
This increases the probability that the valve will perform its safety functlon.
(3) Thermal overload protection can be overridden in an emergency by the ccntrol room operator by holding the control switch in the open or close position.
(4) The overload heaters are sized in accordance with the special service requirements of Intermittent duty motors.
The sizing criterla is such that the motor will rapidly trip If a locked rotor condition occurs, provides sufficient margin for operational loadings, and provides prcrmt Indication.
Item (c)
"Individual valve settings shall be changed, as appropriate, to those estabitsbed 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 maximtm 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 the maximtm differential pressure cannot practicably be performed. This justification should include the alternative to maximtm differential pressure testing which will be used to verify the correct settings.
PECo Response The adequacy of the actual torque switch settings is confinned through stem thrust measurements made utilizing the Motor-Operated Valve Analysis and Test System (MOVATS) and comparing the results with the calculated valve actuator forces required to overcome the maximtm design basis differential pressures. By directly measuring stem thrust, the uncertalnty in the MOV's torque to thrust conversion can be resolved and the required torque switch setting nere accurately determined. This testing forms an integral ccmponent of PECo's I.E.
Bulletin 85-03 program.
All Unit 2 HPCI and RCIC with the exception of M0-2-23-19 (HPCI Inboard injection valve) have undergone MOVATS testing. The physical location of M0-2-23-19 prohibits the Installation of the MOVATS test equipment. The switch setting data for M0-2-23-19 will be derived from the testing of M0-2-23-20 which is identical both physically and fur.ctionally. Differential pressure testing will be performed to confirm the adequacy of the M0-2-23-19 torque switch settings.
Inspection and Refurbishment The "as-found" torque switch settings on trost tested MOVs were found to be within the limits established by a torque switch setting review program conducted in 1975. This derronstrates that torque switch configuration control has been maintained.
During Unit 2 testing, two (2) "open" Ilmit switches and six (6)
"close" limit switches were found to be set improperly. The improper "open" 1Imit swltch settings resulted in MOVs coasting into the backseat and did not affect MOV operation.
The Improper "close" Ilmit switch settings had no detrimental affect.
These swltches provided only pcsItIon Indication and were not functional during valve opening because the "open" torque switch was Jttrpered out. As indicated in the earlier discussion on limit switches, the "open" torque switch bypass switch is on the same rotor as the "close" 1Imit swltch.
._. In cormliance with the Reference 6 procedure on the Unit 2 MOVs, the thermal overload coll sizes and orientations were recorded.
They were then ccrnpared to the size and orientation specifIed on the associated controlled drawing. Two (2) were fomd to be oriented Incorrectly, one (1) was the wrong size, and one was-the wrong size and oriented incorrectly.
In all cases the overload size and/or orientation were such that a higher current was required to trip the valve.. The safety function of the valve was never impaired since the overload will not trip the valve during an auto-actuation.
In addition to notor-operator switch inspections, the Peach Bottcm Program includes a mechanical and electrical Inspection to evaluate the overall condition of the valve notor-operator assently.
Based on the results of these Inspections, worn or degraded parts were replaced, operators were cleaned and relubricated, and other refurbistynent activities were performed as necessary.
Torque Switch Testina A special procedure (Reference 5) has been developed to perforTn the torque switch testing.
This same procedure also provides for torque switch balancing, spring pack preload rework / repair and spring pack shoulder verification.
"As-Found" Testing Results "As-found" MOVATS testing has been performed on all Unit 2 HPCI and RCIC MOVs except M0-2-23-19.
Through this testing, stem thrust signatures were obtained for each MOV before the necessary modifications a.id refurbishments were performed. Tables 2 and 3 contain the results of the "as-found" testing.
Underthrust Conditions: Five (5) of the twenty-four MOVs which underwent "as-found" MOVATS testing were found to generate less than the calculated minimtm thrust at torque switch trip than that required for design basis operation.
The cause of the MOV underthrusting was attributed to one or more of the following conditions:
Torque switch inhalance.
Insufficient spring pack preload, Excessive gap between the spring pack and spring cartridge o
cap which results In rotation of the torque switch without a corresponding increase in stem thrust.
It was agreed between the NRC Resident Site inspector and the PBAPS Compilance Group that the reportability evaluation of the MOVATS diagnosed valve underthrust conditions is to be deferred untti after confirmatory differential pressure / thrust testing is performed folicwing Unit 2 startup.
I
_9._
Overthrust Conditions: Ten (10) of the 24 MOVs which underwent "as-found" M0 VATS testing were found to generate more than the maximtm vendor reconmended thrust at torque switch trip..In eight (8) cases, the valve reconmended maximtm was exceeded; in four (4) cases,. the trotor operator reccomended maximtm had been uxceeded.. The maxinun thrust reconmendations supplied by the valve vendor correspond to those required to operate the valve against maximtm rated cold working pressure rather than being based on detailed stress analyses.
Examinations of the thrust affected operator components yielded no detrimental condition which would have affected valve operability.
Howevor, scme parts were observed to have experienced greater than normal wear. A Ilmiting load for each thrust affected valve comonent was determined and found to significantly exceed the as-found measured thrust in all cases. On this basis, the vendor reccmnended maximtm thrust values are considered to be conservative and the valves which exhibited the overthrusting condition were determined to be suitable for continued service following motor-operator refurbi strnent.
"As-Left" Testing Upon completion of "as-found" testing, the motor-operators were reconditioned as necessary and made ready for "as-left" MOVATS testing.
The Unit 2 "as-left" torque switch settings and corresponding thrust data are contained in Tables 2 & 3.
The data Indicates that all MOVs within the scope of this program meet the. switch setting criteria established and discussed in the Item (b) response.
Instrtmented Differential Pressure Testing l
PECo plans to perform Instrtmented differential pressure testing on 19 of the 24 Unit 2 HPCI and RCIC MOVs.
Instrunented differential pressure testing will entall the monitoring of valve stem thrust, torque switch operation and flow shutoff (verified acoustically) while the valve is operated against differential pressure. Most of this testing must be deferred until after Unit 2 restart since nuclear steam is required. No differential pressure tests have been camleted to date.
An assessment of design basis operating margin for the MOVs at both Units 2 6 3 will be made by ccmparing this data with the "as-left" MOVATS test data.
Table 4 provides an overall stmnary of the testing program.
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 reccmnendations are considered in the preparation of these procedures."
_ _. - _ _ PECo Response As mentioned in earlier discussions, PEco has developed several special procedures to address MOV operability testing and switch verification. These procedures provide the means by which PECo is irrplementing I. E.Bulletin 85-03 at PBAPS.
Infonnation In these procedures which is directly related to the maintenance of MOV switch settings.ls being incorporated into station or Fleid Engineering approved procedures. An extensive revision to maintenance Procedure M-9.1 (Reference 7) is in progress and will reflect this Information. Procedure M-9.1 will also reference the ccatrolled MOV data Index (Reference 8) for making any torque switch adjustments. These procedure revisions will be carpleted prior to Unit 2 restart.
As part of the procedures review, PECo developed a specific list of fdOV maintenarn:e activities which may effect base 1Ine MOVATS results (Reference 9).
Under the PECo progran, all future MOV maintenance will be reviewed against this list to determine what testing must be performed prior to returning any safety-related MOV to service.
Stroke time and motor-current data collected during future surveillance and modification acceptance testing will be canpared to the "as-left" test results in order to monitor valve operability on an ongoing basis.
Item (e)
"Within 180 days of the date of this bulletin, submit a written report to the NRC that:
(1) reports the results of item (a) and (2) contains the program to accanpilsh items (b) through (d) above including a schedule for cenpletion of these items."
PECo Response (Cortplete)
Reference (3) dated Noverrber 3,1986 provided PECo's response to this action item.
Item (f)
"Provide a written report on corrpletion of the above program. This report should provide (1) a verification of camletion of the requested program, (2) a stmnary of the findings as to valve operability prior to any adjustrrents as a result of this bulletin, and (3) a simnary of data in accordance with Table 2, Suggested Data Stmnary Format.
The NRC staff Intends to use this data to assist in the resolution of Generic issue II.E.6.1.
This report shall be submitted to the NRC within 60 days of carpletion of the program.
Table 2 should be expanded, if appropriate, to include a stnmary of all data required to evaluate the response to this bulletin."
.-__ ___ ____ __________ ' Q:
PECo Response This docunent partially cormletes the reporting requirements of I.E.Bulletin 85-03 action item (f) for Peach Bottom. Our plans are to comolete the IEB 85-03 differential pressure testing during PBAPS-2 restart and submit a report ccntaining the evaluated results within three (3) months of its completion. The Unit 3 response will be submitted prior to ullt restart.
. lNIT 3 PROGRAM DIFFERENCES The test program planned for Unit 3 consists of the inspection, refurbishment and "as-left" MOVATS testing of all HPCI and RCIC MOVs.
"As-found" testing is not included in the planned Unit 3 scope of work, since the valve operators will Le completely refurbished and verified operable prior to return to service.
The Unit 3 valves will not be differential pressure tested. The adequacy of MOVATS testing as the basis for determining proper torque switch settings will be confirmed via the results of the Unit 2 instrunented differential pressure test assessment. The Unit 2 differential pressure test results are directly applicable to Unit 3 on the basis of Identical design and operation of the systems and system ccrmonents.
MOTOR OPERATOR MODIFICATI(NS Four modifications concerning MOV operability are being limicmented as part of the PBAPS I.E.Bulletin 85-03 Progran. A description of each modification folicws:
1)
Slots will be machined in the spring pack torque limiting sleeves to alleviate hydraulic locking concerns identified in INPO SER 86-03. Limitorque has approved this slotting scheme.
2)
The electrical Jumer bypassing the open torque switch on all but the HPCI/RCIC Injection and pum discharge valves will be retroved. Since proper torque switch protection will be verified by this test program, there is no need to ccrnpletely override the open torque switch protective feature. Conventional torque switch bypassing, where the open torque switch is bypassed until the disc Ilfts off its seat, will then be put into effect. This rmdification will increase MOV reliability by reducing the Ilkelihood of rmtor burncut and Internal valve damage.
3)
Old style spring cartridge caps on size SMB-000 through SMB-2 operators will be replaced with the newer adjustable type allowing Inservice installation of MOVATS diagnostic equipment.
In addition, this replacement provides the means to reduce the gap between the spring pack and spring cartridge cap which in turn will reduce lost rotaticnal motion of the torque switch. On SMB-3 and SMB-4 size operators, the original spring cartridge cap is being rmdified to allow the Inservice Installation of MOVATS diagnostic equipment.
4).
As a nore positive means of securing the sterrnut locknut, a setscrew is being installed at the locknut /drivesleeve interface.- A setscrew provides easier maintenance disassembly than'the previously used staking method.
PBAPS MOV PROGR#4 BEYOto 1. E. BULLETIN 85-03 PECo is in the process of inplementing a ccmprehensive inspection, refurbishment and test program for all active safety-related MOVs at Peach Bottom. This-program is a direct expansion of our I.E.
Bulletin 85-03 program which was limited specifically to the HPCI and RCIC Systems. The expanded program includes the same engineering and fleid activities described earlier with the exception of "as-found" and instnmented differential pressure testing.
The scope of work will include over 160 MOVs.
SUMMARY
S CONCLUSION This report has described the Peach Bottom I.E.Bulletin 85-03 Program, provided a ccmplete response to bulletin action items a), b),
& d) and provided a partial response to action item c).
The Peach Bottom I.E.Bulletin 85-03 Program will assure the capability of the subject valves to perform their design basis safety functlon.
Future valve-operabi11ty will be maintained through the implementation of revised maintenance procedures.

(*) TEST METHODS A) Baseline M0YATS Testing - all valves except HPCI M0-2(3)- 19 due to inaccessibility.
Identical valve M0-2(3)-20 to be tested for proper torque switch settings.
B) Instrumented differentfal pressure testing. Currently planned for Unit 2 0NLY.
Unit # valves are identical to Unit 2.
C) Non-instrumented differential pressure testing at design basis conditions.
NOTE ( 1) - Elther the HPCI or RCIC vacuum breaker isolation valve will under@ dP testing.
