INTRODUCTION This stress report presents the analysis perfomed to insure compliance with the Equipment Specification and Section III of the ASME Boiler and Pressure  :

i Vessel Code. These gate valves are butit in accordance with the 1974

! edition of the code through the Winter 1975 addenda.

All the valves covered by this report have been designed and analyzed in i i accordance with the NB-3500 rules for Class 1 valves regardless of their actual service application. Throughout this report the specific valve models are identified by the short form of the Westinghouse Electro Mechanical Division model number. These short fann model numbers are related to the i full Westinghouse EMD model number and the Westinghouse FWR valve ID number by the cross-reference that follows this introduction. t l The report is certified to comply with the requirements of NB-3350 and the equipment specification. The " Certification of Compliance" section of this ,

report provides added detail in that area.  !

()  :

Each section of the report is divided into two parts. The first part is a series of tables that list the applicable valves, dirrensions, output I

stresses, and compliance to code. The second part is a generalized fomat that describes the analysis to'be perfomed. All equations are developed l and the allowable stresses are established in these formats.

The tables list more valves than are actually covered by this report. The

reader should simply disregard the model numbers that are not applicable.
i Specific provisions NB-3550 (transient analysis) of the Sucrer 1976 Addenda are used in this report. .

CERTfFICATIO!l 0F CCMPt.1 A!!CE This stress report is certified to meet the requirenents of the ASME i Boller and Pressure Vessel Code, Section !!!, paragraphs flA-3350 and l ldB-3500, and the requireawnts of 0) sign Specification G-952850, Revisien 0, j and G-952851-0. Three specific equipment specification certification  !

requirements are certified based on the information that follows.

The valves covered by this report are certified capable of sustaining the system transients defined in the  ;

equipment specification. Section 7 of this report {

details the calculations performed to show that valves l of six-inch nominal size or larger are capable of L sustaining the system transients as defined in Appendix B of the equipment specification.

The operability of the valves covered by this report will be maintained when the system piping satisfies the -

requirements of equipment specification. This conclusion is based on three pieces of information developed in this stress report. ,

First, the valves satisfy the secondary-stress due-to-pipe-reaction requirements o' bection !!!, second, the valve body crotch cross sectional area and bending modulus are substantially larger than the corresponding pipe valves. -

Therefore, the equipbent specifications nozzle loads which produco l a maximum cobined stress of $y of the connected pipe, would produco much smaller stresses and deflections in the valve. Third and finally, the stress calchletions of Sections 8, 9, and 10 clearly show that the valve bonnet, disc, and main flange bolting meet code and equipment specification allowablo stresses for l faulted loading ccnditions. -

s 1 1 CERTIFICATION OF COMPLIANCE  !

(c,ontinued) l This report certified that nozzle (piping) end. loads f will not affect the structural integrity of the valves ,

covered by this report based on three points. First,the l valves satisfy the secondary stress due to pipe reaction  ;

i requirements of NB 3545.2 (b). Section 6 of this report details those calculations. Second, the SA-182, l Type 316 body and 304 body forging 'naterials have a yield stress at 500'F of 19,900 psi and 19,400 psi respectively, while the connected SA-376 Type 316 pipe f has a yield stress at 500'F of 19,900 psi. These numbers clearly show the raterial strengths are conparable.

Third and finally, the valve crotch cross sectional f area and section modulus are larger than 110 porcent f (Type 316 body) and 114 percent (Type 304 body) than the [

connected piping. Table ! is a tabulation of the  ;

applicable section properties as taken from Section 6 i

'of this report. Since the valve and pipe have comparable

  • material strengths and the valve has much larger section l properties, the pipe loads will cause only sr.all deflections f and stresses in the valve and will not adversely affect j the valve's structural integrity. j l
