SUBJECT:

Beaver Valley Power Station, Unit No. 1 Docket No. 50-334, License No. DPR-66 Supplement to Emergency License Amendment Request for Technical Specification 3.5.2 Regarding One-Time Action for Valve Leak Repair (L-2023-LLA-0027)

By letter dated March 1, 2023 (Accession No. ML23060A018) and pursuant to 10 CFR 50.90, Energy Harbor Nuclear Corp. requested an amendment to the facility operating license for Beaver Valley Power Station, Unit No. 1 (BVPS-1). The proposed change would revise Technical Specification (TS) 3.5.2, ECCS - Operating, Limiting Condition for Operation (LCO) 3.5.2, to add a note (Note 4) allowing a one-time use of an alternate manual flow path to support repair of a leak. The use of the note would expire on April 7, 2023, at 2400 eastern daylight time (EDT). The one-time configuration addressed by the note allows for on-line repair of the leak.

By electronic mail dated March 3, 2023, the NRC staff issued a request for additional information (RAI) to support the review. The Energy Harbor Nuclear Corp. RAI response was provided by letter dated March 4, 2023 (Accession No. ML23063A144).

Subsequently, on March 4, 2023, the NRC staff requested additional documents be provided to support the review of the license amendment request. The requested documents are enclosed.

Enclosure A provides the requested page from a plant work order. Enclosure B provides an engineering calculation that determines limiting test requirements for specific motor-operated valves and evaluates the motor-operated valve to assure that it is capable of performing its required function by design.

1.0 Method of Analysis This calculation will determine limiting test requirements of the subject motor operated valve in two steps.

First, the valve maximum allowable thrust and torque weak link components will be identified as provided by the manufacturer's or supplementary weak link calculations. The operator maximum allowable torque weak link component will also be identified as provided by the listed torque output calculation.

Second, the actuator output torque and thrust required to open and close each valve will be determined.

The summary section then compares the required actuator torque value to the torque available from the actuator under degraded conditions and the minimum valve/operator weak link torque value.

The set-up requirements will be considered acceptable if the required torque value to operate the valve is less than both the torque available from the actuator under degraded conditions and the valve assembly weak link torque value. The summary section also includes the target thrust requirements for rising stem valves, including the packing loads.

A recommended maximum torque switch setting (limiter plate) is being provided with this revision.

This setting should provide operator and valve overload protection for torque limited control schemes. The valve maximum thrust is also summarized in the summary section.

1.1 The valve assembly weak link torque is determined by comparison of the valve weak link torque (obtained from the valve vendor* in DIN 1 ). The actuator weak link torque will be obtained from DIN 3. The component with the smallest weak link torque value will determine the valve assembly weak link torque.

1.2 The output torque of the actuator required to open and close this valve is determined through use of the standard methodology listed in the Limitorque Selection Guide (DIN 7), which is generally endorsed by Velan (DIN 1 ). The JOG MOV Program (DIN 9) requirements will be used in the evaluation. Once the thrust requirements are determined, an additional 5% of the dynamic Stem Thrust (pressure) will be added to account for future degradation, and 10% will be added to the total thrust required value to account for potential Load Sensitive Behavior (LSB). If the Threshold COF values, for disc to seat friction, or a Qualifying Basis is established per the JOG MOV Program requirements (DIN 9), the dynamic stem thrust increase for degradation need not be applied. This will be performed in accordance with DIN 8 & DIN 11, and only applies to valves included in the MOV GL 89-10 program. Note, the stem load component is added only to determine the output torque required to close, not open, the valve. This methodology is described as follows:

2.0 Assumptions 2.1 The Velan Report No. DC-053 (DIN 1) provides stem factors based on a coefficient of friction of 0.15. The more conservative coefficient of friction value of 0.20 (DIN 8) will be used in this evaluation when determining required opening torque. In review of the past performance of this valve, as provided in Attachment 1.0, the maximum stem COF for valve closing was 0.156. This maximum COF value will be used for the stem factor in determining the valve closing torque requirement (Stem Factor =

0.01583).

2.2 The Limitorque Selection Guide (DIN 7) recommends that a valve factor of 0.3 be used for gate valves. A more conservative value of 0.43 is recommended by Velan (DIN 1 ).

The JOG Motor Operated Valve Periodic Verification Program Summary document (DIN 9) recommends that a threshold COF value of.57 be used for valves with a disc-to-seat material of self-mated stellite in a water medium. This COF value of.57 will be used in this evaluation to solve for the opening valve factor. This MOV has been excluded from the MOV GL 89-10 Program for the valve closure function under ECP 06-0339. The valve factor will remain 0.43 for determining the valve closure thrusUtorque requirements.

2.3 The operator thrust maximum allowable is monitored and limited under the MOV testing program. Note: This MOV-1 Sl-836 Limitorque actuator (SB-00) has a maximum thrust rating of 19,600 lbs (DIN 12).

2.4 The valve Stuffingbox (Packing) Load used in this calculation is based on actual measured loads recorded during plant testing (DIN 10).

The measured values are 1747 lbs closing and 1720 opening. For additional conservatism, an additional 33% is added to this load in the analysis section. The calculated value used for Packing Load will be 2324 lbs.

This value will be included when determining the required valve operational thrust requirements.

2.5 The degradation factor described in DIN 8, Section 2.6.1, has not been applied since this calculation uses the JOG Threshold COF for determining the Disc-to-seat drag load (FD) in valve opening. This is acceptable under the requirements of DIN 8, Attachment 4.11. The JOG Threshold COF need not be applied for Non-GL89-10 Program valves; therefore, it has not been applied for valve closure. The Degradation Factor applied for this MOV will be 1.00.

2.6 The maximum operating temperature of this safety injection pipe is assumed to be 215°F, conservatively. This is based on the projected implementation requirements of ECP 06-0227, and updates of the affected pipe stress calculation (DIN16).

3.0 Nomenclature, Acronyms, Definitions LSB - Load Sensitive Behavior - the decrease of output thrust at control switch trip (CST) under dynamic conditions vs static conditions that may occur during valve stroking (also known as Rate of Loading).

COF - Coefficient of Friction DIN - Document Index Number 4.0 Acceptance Criteria This calculation develops the valve limiting test requirements based on the valve design and system operational requirements. This calculation also evaluates the motor operated valve to assure that it is capable of performing its required function by design. The acceptance requirements are discussed in the Method of Analysis section. Should the valve operational torque or thrust requirements exceed the valve assembly torque or thrust capability, then a design change would be necessary.

5.0 Body of Analysis 5.1 Determination of Valve Assembly Weak Link 5.1.1 Valve weak link - The valve weak link thrust will be separated between components above the valve packing and below the valve packing. While testing the valve, the total thrust is measured above the valve packing.

Therefore, the total thrust measured can be higher than the weak link thrust below the valve packing by the measured packing load (i.e. [weak link thrust below packing] + [packing load] = {maximum allowable total measured thrust]).

Check Valve Unwedging Requirements This MOV-1Sl-836 is required to open as a design basis function. In accordance with DIN 11, Section 4.2.7 the unwedging requirements (opening) for gate valves will be checked.

Modified EPRI Revised Unwedging Equation:

Fstat = F - DP X ((Ao X C) - As)

Where:

Fstat =

F=

DP=

Ao=

As=

C=

Maximum allowable static unwedging thrust (lbs)

Actuator capability in the opening direction. Degraded conditions if appropriate (lbs)

Maximum design basis differential pressure (psi)

Mean seating area based on mean seat ring face diameter (in2)

Area of the stem (in2)

Constant based on half-wedge angle (degrees) taken from Table 4-1 Fstat = (250 /.0179)-2745 x ((5.159 x 0.226) -.994)

= 13494.5 lbs Fstat must be greater than the as-left static tested unwedging.

Modified EPRI Theoretical Unwedging Equation:

Fer= ((F - (Fpkc x (1 - B)) - (DP x ((Ao x C) -As)))/ B Where:

Fer=

F=

Fpkc=

DP=

Ao=

As=

B=

C=

Maximum allowable static seating thrust (lbs)

Actuator capability in the opening direction. Degraded conditions if appropriate {lbs)

Packing friction force (lbs)

Maximum design basis differential pressure (psi)

Mean seating area based on mean seat ring face diameter (in2

)

Area of the stem (in 2

)

Constant based on half-wedge angle (degrees) taken from Table 4-2 Constant based on half-wedge angle (degrees) taken from Table 4-2 Fer

= ((250 /.0179) - (2324 x (1-.671)) - (2745 x ((5.159 x.184) -.994))) /.671

= 19858 lbs Fer (19858 lbs) is greater than the closing thrust required (Seating Thrust) (11137 lbs),

and greater than the limiting weaklink in valve closure (16500 lbs); therefore, the MOV setup requirements will be less than the maximum allowable static seating thrust.

7.0 CONCLUSION

S VALVE OPENING The required thrust (11147 lbs) is less than the valve weak link thrust value (16500 lbs) and the actuator thrust limit value (19600 lbs).

The required torque (200 ft-lbs) is less than the valve assembly weak link torque (250 ft-lbs), and the actuator torque available at degraded conditions (281 ft-lbs).

VALVE CLOSING The required thrust (11137 lbs) is less than the valve weak link thrust value (16500 lbs) and the actuator thrust limit value (19600 lbs).

The required torque (177 ft-lbs) is less than the valve assembly weak link torque (250 ft-lbs) and the actuator torque available at degraded conditions (281 ft-lbs).

The valve limiting set-up requirements for this motor operated valve are acceptable. It is shown that the motor operated valve is capable of performing its required design function.

The information derived herein is placed in SAP Functional Location Master Data and is provided to the MOV Program Owner for evaluation of the valve under the NRC GL 96-05 program.

The following thrust quantity is margin provided for future degradation (included in the stem thrust value) and is provided for SAP Functional Location Master Data input:

Margin: Stem Thrust* Degradation Factor O lbs= Stem Thrust* 0.0 8.0 RECOMMENDATIONS The following options provide recommended solutions / potential solutions to allow this MOV (MOV-1 Sl-836) to meet the setup requirements of the JOG MOV Program (DIN 9).

Option 1 -This option has been selected for implementation under ECP 06-0339 and is reflected within this calculation. Exclude this MOV-1Sl-836 from the MOV GL 89-10 Program for valve closure. Change the actuator degraded voltage calculation to utilize the Com-Ed methodology (DIN 3). Change the MOVs setup requirements. Additional margin may be acquired by performing a KALSI study on the actuator to increase the weak link torque (not included in this analysis or the ECP).

Option 2 - Perform a Qualifying Basis through dynamic testing. Change the control switch trip from torque switch seating to limit switch seating. Change the setup requirements, spring pack an~ torque switch setting. Acquire an actuator rating increase. Change the actuator degraded voltage calculation to utilize the Com-Ed Study methodology (DIN 3).

MOV-15I-836 Stem Analysis Objective:

The objective of this weaklink analysis is to increase the allowable stem thrust for MOV-1 SI-836 using a modified methodology similar to that originally used in DIN 1 (DC-053 and 89433-2). The increase in thrust capability is desired to provide additional MOV valve setup margin.

Scope of Analysis:

The scope is limited to the stem at section d1 and A-A as shown in DIN 1 (DC-053 & 89433-2), and the gage diameter section as shown in DIN 1 (89433-2); since these are the weaklink sections desired for an increase in thrust capability.

Summary:

The stem thrust capability for MOV-1 Sl-836 will remain at 16500 lbs (cycle limit removed), with a torque capability of 257 ft-lbs.

Limitations or Restrictions on Calculation Applicability This analysis is limited to, and is applicable to MOV-1SI-836 only. This analysis applies upon implementation of ECP 06-0339.

Impact on Output Documents:

This analysis impacts DIN 1 & DIN 5. DIN 1 & 5 will be revised to provide a cross reference to this analysis.

Method The stem analysis will be performed with consideration to the following methodologies:

1) The weaklink stem area at the ACME threads will be calculated based on the stress area as defined in DIN 19 (Machinery's Handbook). The 3/16" diameter hole through the center of the stem at the threaded length will be subtracted from the area. The thrust and torque loading limits on the stem will be derived based on the use of the maximum principal stress theory, as performed in the original Velan analysis (DIN 1 ). The generalized primary principal stress will be limited to 0.5 times the minimum specified yield strength, and pure shear stress is limited to

.3 times the minimum specified yield strength. This method has been used on other MOV valves (DIN 20), and is considered acceptable under the design basis requirements for BVPS Unit 1.

REVISION:

8700-DMC-2722 8

2) The weaklink stem area at the ACME threads will be calculated based on the stress area as defined in DIN 19 (Machinery's Handbook). The thrust and torque loading limits on the stem will be derived based on independent analyses of the axial membrane stress, the torsion shear stress and the membrane buckling stress. The allowable stress limits will be based on the ASME Ill allowable stress for the axial membrane stress, 0.40 Sy for the torsion shear stress (ASME Ill - NF), and the membrane buckling stress will be limited based on yield strength using the Johnson or Euler equations, as applicable. As discussed in (DIN 22 - NUMARC 91-01 ), "When analyzing non-pressure retaining parts, some reasonable allowable stress should be utilized such as the AISC Steel Construction Specification or ASME code Section NF, which is a slightly modified version of the AISC Specification." This method has been used on other MOV valves (DIN 21 ), and is considered acceptable under the design basis requirements for BVPS Unit 1.

The gage diameter of the stem will also be evaluated with consideration to this third methodology:

3) This method applies to the analysis for the weaklink stem area at the gage diameter. The thrust and torque loading limits on the stem will be derived based on independent analyses of the axial membrane stress, the torsion shear stress and the membrane buckling stress. The allowable stress limits will be based on the ASME NF Code allowable stress; being the axial membrane stress (0.45 Sy), the torsion shear stress (0.40 Sy), and the membrane buckling stress will be limited based on yield strength using the equations of NF-3322, as applicable. As discussed in (DIN 22-NUMARC 91-01), "When analyzing non-pressure retaining parts, some reasonable allowable stress should be utilized such as the AISC Steel Construction Specification or ASME code Section NF, which is a slightly modified version of the AISC Specification." This method is considered acceptable under the design basis requirements for BVPS Unit 1.

Conclusion The maximum stem thrust force will remain limited to 16,500 lbs. The maximum stem torque will be limited to 257 ft-lbs (16500 x 0.0156) which is based on a stem factor coefficient of friction of 0.15).

The limiting section for stem loading is the gage diameter. Method 1 shows an allowable thrust of 14020 lbs at the maximum accident temperature {environmental) of 215 F. Method 2 shows an allowable thrust of 15113 lbs at a temperature of 100 F through 300 F. Method 3 shows an allowable thrust of 18070 lbs at the temperature of 215 F. The vendor analysis (DIN 1, 89433-2) shows an allowable thrust of 16500 lbs being limited to 8188 cycles. With consideration to the vendors' analysis and the method 3 analysis results above, the stem load will be limited to 16,500 lbs thrust and 257 ft-lbs torsion. The industry guidance (DIN-22, NUMARC 91-01) states; "When analyzing non-pressure retaining parts, some reasonable allowable stress should be utilized such as the AISC Steel Construction Specification or ASME Code Section NF, which is a slightly modified version of the AISC Specification". The cycle limitation will be removed in that, a) the method 3 approach does not require a fatigue analysis since the MOV will not experience high cycle fatigue {cyclical loading in excess of 20,000 cycles), and b) the cycle limit derived in DIN 1 is 8188 cycles which also will not be experienced in the 60 year life of the plant.
