Dear Dr. Grace:
Carolina Power & Light Company (CP&L) hereby submits information requested by IE Bulletin No. 85-03, "Motor-Operated Valve Common Mode Failures During Plant Transients Due to Improper Switch Settings," dated November 15,1985 and Reference 5. The subject Bulletin required that a design basis review be performed and a program be developed and implemented to ensure that switch settings for certain safety-related, motor-operated valves (MOV) are properly selected, tested under simulated conditions, and correctly maintained. Results of the design basis review were submitted by Reference 1.

Dr. J. Nelson Grace NLS-88-093/ page 2 Attachment I to this submittal comprises a report detailing CP&L's completion of the IEB 85-03 program. The report provides a verification of completion of the requested program, a summary of the findings as to valve operability prior to any adjustment resulting from the subject Bulletin, and a summary of data as suggested by Table 2 of the Bulletin. This report provides the information required by Action f of the Bulletin.
Attachment 2 specifically provider that inform 6 tion requested by Reference 5. Where appropriate, this information is also contained in Attachment 1. This letter is submitted within the time frame as discussed with Mr. E. D. Sylvester on May 16,1988.
Please note that as stated in Reference 4, the BWROG is re-evaluating valve differential pressures on the nine NRC selected MOVs, considering inadvertent valve operation. This BWROG re-evaluation is being undertaken with the understanding that assumptions are required that are outside the existing BWR ECCS design basis. CP&L will address changes to the valve dif ferential pressures for the five NRC selected MOVs applicable to BSEP, upon completion of the BWROG re-evaluation. A report providing the results of the above design basis evaluation per Action (a) of NRC Bulletin 85-03, Supplement I and a schedule for implementing Actions (b) through (d) will be submitted within 30 days of our receipt of the BWROG re-evaluation.
Should you have any questions regarding this topic, please contact Mr. Arnold Schmich at (919) 836-8759.
Yours very truly, L. W. Eury LWE/AWS/lah (5406AWS)

i Final Response to NRC IE Bulletin 85-03 The following sections provide specific detail on each of the IEB 85-03 action items.
References 1, 2,3,4, and 3 refer to the references listed in the cover letter.
A. Design Basis Information Action (a) requires that CP&L review and document the design basis for the I 1
operation of the MOVs in the High Pressure Coolant Injection (HPCI) and Reactor Core isolation Cooling (RCIC) Systems required to be tested for operational readiness in accordance with 10CFR50.55a(g). This documentation should include the valve.
the maximum expected differential pressure during both opening and closing of Tne Boiling Water Reactor Owners' Group (BWROG), of which CP&L is a i
member, developed a program to address Action (a) of the Bulletin on a generic l i basis. Reference 3 provided this generic methodology. The valves analyzed as requiring calculation of the differential pressures in the BWROG Report are i listed in Tables I and 2 of Reference I and Tables I and 2 of this response, along '
with the maximum expected differential pressure in the direction of opening and/or closing. It should be noted that Tables I and 2 (of this response) contain ,
i additional valves and/or pressures not contained in the initial BSEP response (Reference 1). These additional valves / pressures were added in response to Reference 5.
d i
Calculations of the maximum expected differential pressures provided in Reference I were based on the BWROG generic methodology and contained }
several very conservative assumptions. Due to the excessively conservative assumptions contained in the BWROG generic methodology, the calculated t ditferential pressure for several MOVs was listed as greater than the actual value. For inose valves affected, the revised data and the basis for deviation from the generic methodology was presented in Reference 2. !
The valves analyzed as requiring calculation of the differential pressures in the BWROG report are listed in Tabies I and 2, along with the maximum expected dif ferential pressure in the direction of opening and/or closing. A discussion of the valve function, design basis, and differential pressure location ,
1 (upstream or downstream) are provided in the BWROG report. As indicated in i Reference 4, the BWROG is re-evaluating valve dif ferential pressures to the nine l NRC selected MOVs, considering inadvertent valve operation. The BWROG re-evaluation is being undertaken with the understanding that such anessment ,
i requires assumptions outside the existing BWR Emergency Core Cr., ling System design basis. CP&L will address any changes to the valve differential pressures for the five NRC selected MOVs which are applicable to BSEP, upon completion of the BWROG re-evaluation. This information will be provided in accordance ;
with the requirements of IE Bulletin 85-03, Supplement 1.
For the valves in Tables I and 2 added by this response, the methodology utilized to calculate the maximum expected differential pressures is presented below:
2 (5406AWs/che)
MOV E41-F008 MOV E41-F003 is the HPCI pump CST Test return line isolation valve, and discharges to the CST. As discussed in the BWROG Report, this valve has no safety function. The valve is normally closed, and is only opened for testing or reactor pressure control.
Since the valve is a globe valve, flow will assist in opening the valve. With the opening torque switch jumpered out, ful! motor torque can be applied to opening the valve. Maximum pressure is expected upstream of the valve
' and , therefore, assists in opening the valve. For these reasons, the valve opening ditferential pressure is of no concern. For conservatism however, the existing valve design differential pressure of 1140 psid has been utilized for this response.
BSEP procedures call for closing this valve under various conditions. These include closure af ter turbine shutdown, closure at a turbine speed of
' 3300 rpm (920 psi pump discharge pressure), and closure upon transfer of flow paths following an automatic initiation. In this final case, the injection valve is open before this valve reaches the full closed position.
Line pressure is then only slightly (approximately 40 psi) above reactor pressure. The dif ferential pressure resulting from valve closure, the "water hammer" term, does not apply. This term accounts for the deceleration of the fluid during closure and uses the pressure wave movement through the pipe. Since this valve is not closed until another flow path is available, the pressure wave is eliminated by the flow path. The actual closing dif ferential pressure is, therefore,1140 psid.
MOV E4l-F011 MOV E41-F0ll is the redundant CST Test return isolation valve for both HPCI and RCIC, and discharges to the CST. As discussed in the BWROG Report, this valve has no safety function. The valve is normally closed and is only opened for testing or reactor pressure control. The opening torque switch is jumpered out; therefore, full motor torque can be applied to opening the valve. Maximum pressure is expected upstream of the valve.
BSEP procedures call for opening this valve under conditions of negligible differential pressure. This valve is opened prior to the opening of the E41-F008 or E51-F022 valves which isolate it from each system and, therefore, from high upstream pressures. For conservatism, the pressures obtained for the E41-F008 valve have been used for this valve also.
This salve is closed under conditions ranging from no differential pressure, to that seen upon transfer of flow paths following an automatic initiation.
The same rationale utilized for the E41-F008 valve applies to this valve.
Therefore, the same closing ditferential pressure also applies (1140 psid).
MOV E31-F022 MOV E51-F022 is the RCIC pum9 CST Test return line isolation valve, and discharges to the CST. As discussed in the BWROG Report, this valve has no safety function. The valve is normally closed, and is only opened for testing or recctor pressure control.

Since the valve is a globe valve, flow will assist in opening the valve. With the opening torque switch jumpered out, full motor torque can be applied to opening the valve. Maximum pressure is expected upstream of the valve and, therefore, assists in opening the valve. For these reasons, the valve opening dif ferential pressure is of no concern. For conservatism, however, the existing valve design differential pressure of 1140 psid have been utilized for this response.
BSEP procedures call for closing this valve under various conditions. These include closure af ter turbine shutdown, closure at a turbine speed of 2300 rpm (340 psi pump discharge pressure), and closure upon transfer of flow paths following an automatic initiation. In this final case, the injection valve is open before this valve reaches the full closed position.
Une pressure is then only slightly (approximately 110 psi) above reactor pressure. The differential pressure resulting from valve closure, the "water hammer" term, does not apply. This term accounts for the deceleration of the fluid during closure and uses the pressure wave movement through the pipe. Since this valve is not closed until another flow path is avr.!!able, the pressure wave is eliminated by the flow path. The actual closing differential pressure is, therefore,1140 psid.
B. Switch Settings Action (b) requires that the correct switch settings be established for the differential pressures calculated in Action (a) above. It also re estabilshment of a program to review and rovise, as necessary, the methodsquires for the selectin and setting all sw!:ches (i.e., torque, torque bypass, limit, and overloa .
The procedures used to set torque switch bypass and position limit switches at BSEP have been reviewed and found to be acceptable. Switches are set four-percent from the full-opened and full-closed positions unless otherwise evaluated. The four-percent positions are determined by the total number of handwheel turns for the valves (listed on the data sheet). The problem
! encountered at Davis-Besse 1, as a result of counting handwheel turns, is not considered applicable to BSEP since for those valves governed by this Bulletin that are required to open against a differential pressure, the open torque switches are jumpered out for the full stroke of the valve. For those valves ,
i reciuired the valve. to close, the limit switch is jumpeted out to allow for torque seating of The methodology used to determine overload protection setpoints has been reviewed and found to be acceptable. This methodology (coordination !
verification and component selection for safety-related valves) has been established using the guidance of Regulatory Guide 1.106 in that the uncertainties with respect to coordination are resolved in favor of the valve performing its design function.

- A ma}ority of the valves in this response (see Table I and 2) were tested against the calculated dif ferential pressure, or a larger value, by the valve vendor prior to shipment. The actuator design torque values supplied by the valve vendor ,
have, therefore, been previously verified and will be used as the minimum allowable torque value. The same philosophy applies to those valves that are "type tested". The required torque settings for these valves are listed in Tables i and 2.
I For those valves that do not fall into the above grouping, the actuator torque -
required for proper operation against the calculated differential pressure was J determined based on the valve vendor input, the actuator vendor input, and, as required, the results of differential testing. The methodology for determining ,
the required torque settings for the valves in this grouping are detailed in Section C below. The required torque settings for these valves are listed in Table 1 and 2. <
The Unit i valve actuators that are subject to the requirements of the Bulletin ,
were completely rebuilt prior to stroke testing and therefore the "as-found" -
3 operability cannot be directly determined. There were no significant problems j
noted during the rebuilding or stroke testing of the Unit I actuators that would ,
have been expected to result in valve inoperability. No valves tested as a result '
4
. of this Bulletin were determined to be inoperable.
b C. Valve Testina '
Action (c) requires that valve torque switch settings shall be changed, as -
appropriate, to those determined in Action (b) above. This item also requires valve testing at the differential pressure calculated in Action (a) above, except where that ditferential pressure is the result of a line break.
- i j The initial respunse to IEB 85-03 (Reference 1) specified that for valves for which dif ferential pressure test data at the calculated differential pressure could l
- not be found, or ior which a "type test" valve could not be found, a test would be ,
i performed. Two such tests were required.
3 q
! The first test was for the HPCI and RCIC turbine exhaust line vacuum breaker t
- Isolation Valves 1-E41-F073,1-E41-F079,1-E51-F062, and 1-ESI-F066, '
respectively. These valve / actuator assemblies are identical, and so meet the criteria for "type testing". The 1-E51-F062 was chosen for the test.
i Special Procedure 87-022 was written to control and document the testing. The '
testing was done at the 27 psid value calculated for the valve, and the valve '
i opened and closed properly at this differential pressure. Prior to the differential pressure test, the valve was verified to torque out at 34 f t-lbs. This torque value will therefore be the minimum setting allowable for the four valves mentioned !
j above. !
i l The second test was for the HPCI pump Condensate Storage Tank Suctier. 1 j i Valve 1-E41-F004. Special Procedure 87-028 was written to control and 3
- document the testing. The testing was done at a 38 psi differentidl. The caly ;
available test connection upstream of the valve is a 3/4-inch vent lin .
{ Sufficient flow could not be maintained to keep the downstream
- open using this 3/4-inch connection. The valve therefore closed nlve !

phase, therefore, Anchor Darling (the valve vendor) was requested to evaluate the valve / actuator assembly at a differential pressure of 43 psid. The vendor responded that the valve / actuator assembly was acceptable at the higher differential pressure, and no adjustments were necessary. Based on the Anchor Darling response, no additional pressure testing was performed. This testing would have required disassembly of the downstream check valve for an adequate test.
The valves governed by this Bulletin were stroke tested in both the open and closed direction with the actuator output torque, spring pack deflection, spring force, and motor current monitored for each valve. The as-found and as-lef t actuator output torque for each valve is listed in Tables I and 2.
D. Control of Switch Settings Action (d) requires that procedures be prepared or revised to ensure that the correct switch settings are determined and maintained throughout the life of the plant.
The initial response to IEB 83-03 (Reference 1) specified that a procedure would be initiated to control the limit and torque switch settings for the valves of concern. The necessary requirements for changing a setting were also to be given. Engineering Procedure ENP-43, "Motor-Operated Yalve Switch Settings,"
was therefore written to satisfy this requirement.
ENP-43 was originally written to specify HPCI and RCIC MOV torque and limit switch settings. This procedure has since been expanded to cover safety-related MOVs in general. Additionally, ENP-43 was revised to specify actuator torque requirements instead of torque switch settings, since torque switch settings alone may not guarantee that the actuator will develop adequate torque / thrust.
Torque switch settings are no longer used as the sole acceptance criteria for setting up actuators since the actuator torque / thrust can vary depending on the "stifiness"(spring constant and force preload) of the spring-pack.
ENP-43 ider tifies the responsibilities of the various personnel involved in the control and adjustment of limit switches and actuator torque, and provides the guidelines necessary to ensure this control is maintained. It provides for informing the responsible System Engineer of all changes, and covers the methodology to be used to evaluate changes for settings outside the approved range.
I&C and mechanical technicians have been trained to set limit and torque switches and in general MOV maintenance by INPO accredited Craf t and Technical Development training (C&TD). C&TD training is both formal and documented. In addition, the technicians receive on-the-job training on installed equipment in the plant. Technicians set the switches in accordance with detailed, approved maintenance preceArcs. Selected technicians, mechanics, and maintenance engineers have received specialized training from Limitorque on diagnostic testing and evaluation of diagnostic test results. Additionally, selected I&C and mechanical technicians have received detailed, specialized training from Power Safety on the maintenance of Limitorque valve operators.

Response to NRC Request for AdditionalInformation Concerning the Initial BSEP Response to IE Bulletin 85-03 NRC REQUEST: 1. Revise Tables 1 and 2 of the response dated October 2,1986 to include the following MOVs, or justify their exclusion. As required by Action item a of the Bulletin, assume inadvertent '
equipment operations:
(a) HPCI MOV F007 is shown normally open in Zone B-6 of Drawing D-25023, Sheet 1, Revision 28 (Unit 1), and as MOV 8 on page 68 of BWROG Report NEDC-31322 dated September 1986. How would injection to the reactor vessel be ensured if this valve were to be:

Action (b), "Switch Settings." position is provided in Attachment 1, NRC REQUEST 6.
The proposed program for Action items b, c, and d of the Bulletin is incomplete. Provida the following details as a minimums (a) commitment to a training program for setting switches and maintaining valve operators, (b) commitment to justify continued operation of a valve determined to be inoperable, i' i

, l (c) description of a method possibly needed to extrapolate valve stem thrust determined by testing at less than maximum differential pressure, (d) justification of a possible alternative to testing at maximum differential pressure at the plant, (e) consideration of pipe break conditions as required by the bulletin, (f) stroke testing when necessary to meet Bulletin requirements, and n
(g) consideration of applicable industry recommendations in the preparation of procedures to ensure maintenance of correct switch settings.
CP&L RESPONSE (a) A description of the training provided to maintenance personnel who work with limitorque actuators is provided in Attachment 1, Action (d), "Control of Switch Settings."
(b)
A commitment to justify continued operation with inoperable valves is not required. This is inherent in existing plant operations methodology. If a motor-operated valve is inoperable, system operability is dispositioned in accordance with the Technical Specifications for that system. If an LCO was generated as a result of the condition, the LCO cannot be canceled unless the condition is corrected or evaluated as acceptable by an engineering evaluation in accordance with ENP-12. The engineering evaluation is the required justification for continued operation.
(c)
This item does not apply to BSEP. Valve testing was performed at the required differential pressures, or justification provided for not testing the valve. BSEP does not intend to test valves at less than the maximum differential pressure. The statement in question was included in the initial response since test methods had not been ,
finalized at that time.
1 (d) Same as (c) above.
(e) lE Bulletin 85-03 requires consideration of pipe break conditions in the determination of valve differential pressures, when a line break is part of the design basis for that valve. It also requires that the resulting switch settings should be verified, to the extent practical, by the same methods that would be used to verify other settin not tested at the maximum differential pressure.gs that are i I
BSEP participated in the BWROG program that addressed the subject Bulletin on a generic basis. The report prepared by i the BWROG (Reference 3) took into account line breaks as !
required by the Bulletin when determining valve differential 4 i l

pressures. As for verification of the associated switch settings, the differential pressures obtained for the subject valves were less than the existing design differential pressures of the valves. Therefore, as discussed in the initial response for BSEP (Reference 1), the settings have been previously verified to be acceptable and additional testing is not required.
(f) IE Bulletin 83-03 requires that each valve be stroke tested, to the extent practical, to verify that the settings defined in Action (b) of the bulletin have been properly implemented.
This testing is required even if testing with differential pressure cannot be performed.
As detailed in Attachment 1, Action (c), "Valve Testing," the valves contained in the response were stroked in both the open and closed directions. Actuator output torque was measured during this testing, with the as-found and as-left torque values provided. No further action is required.
(g)
Attachment 1, Action (d), "Control of Switch Settings,"
provides details on the procedure developed to ensure that switch settings are properly maintained, The torque requirements referred to in the response are the minimum and maximum values for each valve. The minimum value is that required to ensure proper operation at the specified differential pressure, while the maximum is that which will not exceed the rating of the spring-pack, the actuator, the '
motor, or the valve itself. Criteria more restrictive than that used by the actuator manufacturer was utilized.
