A.two-level system is used for the seismic classification of structures, components, and systems other than Westinghouse's scope of the Alvin W. Vogtle Nuclear Plant (VNP) :

l tT Category I Structures, Components, and Systems l Y-sl Category.II Structures, Components, and Systems l For Westinghouse design responsibility components refer to RESAR-3, sections 3.2, 3.9 and 5.2. In addition to the I'i standard systems described in RESAR-3 above, refer to tables

(_)

6.2-12, 9.3-2, 9.1-2, and 10.4-1 of the PSAR for the safety classification of the Westinghouse components in the containment spray system, boron recycle system, spent fuel pit cooling system and steam generator blowdown system.

The classification of pipes, valves, and fittings is shown on the piping and instrumentation diagrams in the appropriate PSAR sections.

3.2.1.1 Definitions

,s Seismic Category I structures, components, and systems are

(' ') defined in accordance with USAEC Safety Guide No. 29 as those necessary to assure:

The integrity of the reactor coolant pressure boundary.

The capability to shut down the reactor and maintain it in a safe shutdown condition.

The capability to prevent or mitigate the consequences of accidents that could result in potential offsite exposures comparable to the guideline exposures of 10 CFR Part 100.

! )

(_/ Category I structures, components, and systems are designed to withstand the appropriate seismic loads and other applicable loads without loss of function. Category I structures are sufficiently isolated or protected from Category II structures to ensure that their integrity is maintained at all times.

\_ Category II structures, components, and systems are those whose failure would not result in the release of significant (3

Specifically, all non-Category I systems, equipment and components that are installed in Category I structures are carefully examined to determine the degree, if any, of detrimental effect on safety related systems, should failure of the non-Category I equipment, systems or components occur. Where the detrimental effect can be shown to effect safe shutdown equipment then the non-Category I item is either upgraded to Category I or separated by distance or barricade.

The failure of Category II structures, components and systems may interrupt power generation.

Using the allowables and analytical techniques given in Appendix 3N, it is determined that a 2'-0" thick reinforced concrete wall could resist the impact effects of all the listed missiles without perforation, spalling or failure due to structural response.

3.5.3.4 Protection of Structures, Systems and Components Against External Missiles l The Category I structures listed below are analyzed for missile damage protection capabilities and for compliance with the protection criteria of this section. The bases for. selection of these structures for analysis are: (1) they house or service systems and components required for the safe shutdown of the reactor and to maintain it in a safe shutdown condition, (2) if damaged, they could cause uncontrolled release of radioactivity that could result in potential offsite exposure comparable to the guideline exposures of 10 CFR 100.

Similarly, breaks should be assumed to occur at any intermediate locations between terminal ends of piping runs or branch runs that exhibit stress intensities above conservatively derived limits

The shear modulus corresponding to' low shear strain levels.(10-4 % or less) for this stratum was computed based on the meas" red shear wave velocity of 1800 ft/sec. To account for the variation in the

-( measured shear wave velocity with the depth, a range of. shear q ,) moduli with upper-bound values equal to 1.5 times the mean values and lower-bound values equal to the mean values divided by 1.5, will be used in the analysis.

In general, the soil perties are nonlinear in character. An iterative process is ;d to obtain equivalent linear properties which are strain dep 4ent. The methods generally used for such an analysis are inc12aed in the computer program FLUSH.

The generation of design time history motions is described in section 3.7.1.2. This ground motion is defined for the free field and applied at the finished grade level (El 220'-0") of the site.

The time history at the base of the idealized soil profile is 7 s, obtained through deconvolution analysis of'the design time t

'-'j history specified at finished grade level, using appropriate soil properties. The time history, thus obtained, is applied at the base of the soil-structure interaction system, with appropriate soil properties for soil-structure interaction analysis. The resulting time history response will be used to generate the in-structure response spectra at selected floor elevations. The analysis is performed with consideration S4 given to the variation of soil parameters as indicated above using appropriate cut-off frequencies such that the acceleration profile in the free field is realistic. .The " envelope in-structure response spectra" shall be' developed by enveloping the response spectra obtained by considering the variation of soil properties.

Response spectra corresponding to the free field' time history

. motions calculated at the elevations of Category I structural foundations are generated. Considering the variation of soil properties, " envelope response spectra" for each Category I foundation level is developed. A scaling factor of 1.5 has

/~ been established such that-when the " envelope response spectra"

The " envelope S5 in-structure response spectra" curves generated for each deeply embedded seismic Category I structure will be multiplied by the scaling factor of 1.5 to obtah the " design in-structure f-'g response spectra" curves.

VNP 10.3 MAIN STEAM SUPPLY SYSTEM 10.

3.1 DESCRIPTION

Steam at the outlet from the four steam generators, a total of 15,155,582 lb/hr at 985 psia, 542.8 F, and 0.25 percent moisture is routed in the main steam piping to the turbine at a total pressure drop of 20 psi at the turbine guaranteed steam O flow condition. As percent power demand increases, the steam generator outlet steam pressure decreases from 1107 psia, 556 F near zero percent power to 985 psia, 542.8 F at 100 percent power. Consequently, the turbine inlet pressure decreases as the load increases.due to this characteristic of the steam g

generators.of the NSSS.

The main steam piping headers conduct the total steam flow from the steam generators to the turbine; one line size is 38 inches, the other'is 44 inches as shown in figure 10.1-3 and 10.1-4. Each main steam line is sized to provide a required equal balanced steam pressure at the inlet to the turbine stop valves. The pipe sizes selected are based on different pipe lengths of the unsymmetrical steam piping layout with the present reactor building orientation to the turbine building.

The design pressure-temperature rating of the main steam piping is 1185 psig 600 F, which matches the design pressure-temperature rating of the steam generator secondary feedwater-steam side.

10.3.2 PIPING COMPONENTS AND SYSTEMS In evaluating the design of the main steam system-piping, the following components and/or systems are considered:

A. The attachment of the main steam piping to the steam generators takes into account the allowable nozzle loading movements and stresses as specified by the steam generator manufacturer for all four units operating or with units out of service.

k B. The routing, loading, and support of the main steam piping through the penetration section of the reactor containment building for various unit operating conditions are determincd.

C. The loading and support of the main steam line O isolation valves just outside the containment building are determined.

VNP D. The' sequential blowing effect of the steam safety valves and atmospheric. power relief valves located in  ;

~

the main steam piping between the containment building and the main steam line isolation valves and  ;

the resultant valve reaction thrusts on the piping is i determined.

E. The routing and support of interconnected steam l piping.to the reheaters, the turbine bypass system to l the condenser, and the main steam generator turbine driven feedwater pumps for normal, upset, and emergency conditions are determined.

'F. The interfacing of the main steam lines with the. main l turbina stop/ control valves is determined, taking _

l into account allowable loadings, movements, and stresses as specified by the turbine-generator .

manufacturer for normal conditions, on line stop i valve-testing conditions, and upset conditions.

G. For the foregoing systems and components relating to the main steam piping, the requirements are calculated as outlined by the specific applicable codes and classes as shown on the respective system diagrams.

Steam is conducted from each steam generator in 26-inch lines through the containment building, the lines being anchored at the containment wall. The lines are designed in accord with 55 subsection 3.6.2.G.2, up to and including the anchor forging at the end of the MSIV/MFIV area. The isolation valves and the spring-loaded safety and atmospheric power relief valves are located outside the containment building.

10.3.3 VALVES 10.3.3.1 Safety Valves Five spring-loaded safety valves in each 36-inch steam outlet line as shown on figure 10.1-4 are designed and selected in accord with the requirements of the ASME Boiler and Pressure' Vessel Code,Section III Nuclear Vessels. The lowest safety valve is set at 1175 psig, the design pressure of the steam generator (minus 10 psi piping loss). The highest safety valve setting is 105 percent of the design pressure at 1234 psig.

VNP If the break is downstream of the isolation valves, the S5l automatic isolation valves would close within 10 seconds from receipt of the initiating signal.

W For the condition of a steam generator tube rupture, the isolation valves serve to limit the total radioactive release to the environment by isolating the damaged steam generator.

A flow restrictor is installed within each steam generator outlet nozzle and is primarily used to limit the steam flow release in case of a main steam line rupture. Steam flow is measured using the pressure drop between the steam generators and pressure taps in the main steam lines downstream of the flow restrictors.

Three-inch lines connected upstream of the isolation valves (see figure 10.1-4) in the steam outlet line from three steam generators provide steam to the turbine-driven auxiliary feedwater pumps. This assures a source of steam to the turbine-driven auxiliary pump when the steam generators are isolated and are producing steam from reactor decay heat. The 3-inch steam piping to the auxiliary turbine feed pump is designed to the ASME Code Section III Class 2.

Main steam piping is cross-connected downstream of the main steam line isolation valves. The bypass valve around the main S5 steam isolation valves will be designed for Nuclear Safety Class 2 and seismic Category I. Branch piping from the cross-connections provides steam to the reheaters, gland steam sealing system, steam air ejectors, the steam generator feedwater pump turbines, and the turbine bypass steam to the condensers (see figure 10.1-3).

Main steam piping in the main steam tunnel downstream of the anchor forging at the end of the MSIV/MFIV area is designed in accord with the Power Piping Code ANSI-B31.1.0.

55 Anchor forgings shall be provided at both terminal points for main steam and feedwater piping located in the main steam tunnel.

In addition, pipe whip restraints shall be provided at the two intermediate high-stress points, as well as in the proximity of the auxiliary feedwater tunnel.

The specification for th'e main steam and feedwater line isolation valves will require each prospective vender to provide a detailed description of environmental qualification as well as the provisions for inservice tests. Environmental SS qualification will satisfy the environment which results from the breaks postulated in accordance with subsection 3.6.2.G.2. Inservice inspection tests will be performed periodically to demonstrate that these valves will function in accordance with design. The procedure will be available after a proposal is accepted.
