Calculation Subject Valve thrust calculation for MOV 857A, B and C and 860A, B, C, and D.These are 6"x4"x6", 300 lb.Class, gate valves produced by Anchor/Darling Valve Co.with Limitorque SMB-00-7.5 Actuator, and installed in the Residual Heat Removal System of RGGE's Ginna Station.Objective of Calculation The objective of this calculation is to determine the structural weak link of the valve components and to determine the limiting thrust values based on these components.
This calculation is performed to comply with the requirements of NRC Generic Letter 89-10 (GL 89-10)[7].Calculation Methods and Assumptions The evaluation consists of equating stresses for critical components caused by thrust and torque to the appropriate allowable stress and then solving for the resulting allowable thrust.The valve thrust limits are the minimum of the evaluated thrust for the various components and operating modes.Design Basis 6 References Stress limits for all valve components are as specified in the appropriate edition of ASME Section III, Subsection NC[5]as specified by the Ginna Station UFSAR[1].Non pressure boundary components are qualified to the requirements of ASME Code Case N-62[6]~Brackets,"[]", indicate references identified in Section~of this document.Conclusions The resulting valve thrust limits are: 9,027 lbs.closing 9,027 lbs.opening 23,794 lbs.backseating 91187.C06

A minimum thrust is required to operate the valve under design conditions.
A maximum thrust limit must be specified based on the structural capacity of the valve components.
This thrust, along with the minimum required thrust, will provide a working range for the valve.Appropriate torque, switch settings and periodic testing will ensure that the valve thrust does not drift outside of this working range.The thrust limits for valves 857A, B and C and 860A, B, C, and D have been determined by Altran as follows: 1: Data Collection 4 In order to obtain critical dimensions, material identification, and stress data the following steps were performed:

2.Identify Structural Weak Link Calculations were performed to identify the structural weak link among components which are exposed to thrust loadings.These included the valve stem, bolts, disk, yoke, and other components which may or may not be part of the pressure boundary, but are affected by thrust loads.As appropriate, pressure, seismic, and deadweight stresses were included in the evaluation of valve components.
3.Calculate Thrust Limit A maximum thrust load limit for the valve was calculated.
Details for the above tasks are summarized in the following sections of this calculation.

Therefore deadweight and seismic loads are included in the evaluation of structural components such as the yoke, operator, bolts, etc.The weight of the operator is significantly greater than the weight of the valve parts affected by this calculation and therefore, only the weight of the operator is included.Conversely, the magnitude of the deadweight and seismic loads on the valve internals is negligible in relation to the thrust and pressure loads, and therefore are not considered in the evaluation of internal components such as the disk, seat, stem, etc.Under the Ginna Station Seismic Upgrade Program (EWR-2515)12], all valves require a seismic qualification at 2.1g horizontal and vertical loading unless otherwise specified in the pipe stress evaluation.
The valve included in this calculation was reviewed and determined to be bounded by these accelerations.
Therefore, a uniform seismic acceleration of 2.1 g s in all directions was conservatively applied.For these calculations the valve stem was conservatively assumed to be oriented in the horizontal direction, therefore lc.No.: 91187-C-06

[20]using yield strength as a criteria and including pressure loads only.This calculation was then modified to use ASME section III criteria and to include seismic loading.The yoke, bonnet bolts, and operator hold down bolts are recalculated to include seismic loads.The calculation for these components were performed using simplifying assumptions.
As these calculations were similar for corresponding parts of different valves, the calculations were automated using the spreadsheet program QUATTRO PRO[16].The spreadsheets are designed to present important input variables, and calculate stresses and allowable thrusts.A printout of each spreadsheet is included in Appendix IV.The remaining components'alculations were modified to include the appropriate ASME Section III allowable stress by factoring the results from the yield strength analysis.5.2 Criteria Stress limits for all valve components are as specified in the appropriate edition of ASME Section III, Subsection NC

Comparison of ASME Code Case N-62[6]criteria with ASME Section III, Table NC-3521-1[5]criteria indicates that it is appropriate to use Table NC-3521-1 criteria for both pressure retaining and non-pressure retaining components.
The Level A service limits of Table NC-3521-2-1 are used'o evaluate non-seismic loading conditions for the components evaluated.
The Level D limits are used to evaluate loading conditions which include seismic loads.Membrane Stress 1.OS Membrane+Bending Stress 1.5S Shear Stress will be limited to 0.6S.Bearing Stress will be limited to Sy.The resulting criteria to be satisfied are: Non-Seismic Seismic 2.0S 2.4S The thrust limit for the valve will be the minimum thrust for all components as determined from the above criteria.The thrust limit for backseating of the stem with the, bonnet backseat (stellite region)is limited to the stem yield stress assuming a 1/16" wide strip at the stem outside diameter.

Stem backseating thrust is also calculated as part of the stem evaluation.

[20]evaluates the yoke flange and the operator mounting flange for normal operating conditions.
The yoke flange is a double slab flange type with four bolts compared to a circular flange with four bolts for the operator mounting flange.The moment arm to the operator center line is larger and the width of action smaller for the yoke flange.Therefore, the yoke flange is limiting, as confirmed by the vendor calculation, so that the operator mounting flange need not be evaluated further.The combined bending and shear stress is calculated for the yoke mounting flange and equated to 1.5S for normal conditions and to 2.4S for faulted conditions.
5.3.6.1 Yoke Flange Analysis The following stress equations apply to a quadrant of the double slab yoke flange, shown Figure 6, and are based on the analysis and parameters from the Anchor/Darling valve calculation
[20].
