GE-NE-123-E070-0493 ABSTRACT This report documents the results of a pipe break analysis performed at the request of the NRC for a GE Advanced Boiling Water Reactor (ABWR) main steam line following a postulated circumferential break in the main steam line where it connects to the reactor pressure vessel nozzle. This report supports the ABWR Standard Safety Analysis Report (SSAR) and supplements Appendix "3L" of the SSAR, " Procedure for Evaluation of Postulated Ruptures in ,

High Energy Pipes."

This pipe break analysis illustrates GE's pipe break analysis methods. It also addresses the specific NRC questions regarding the GE methodology raised during the NRC audit of the SS AR. These NRC concerns are listed below:

(1) Document GE procedure for calculating the forcing functions for line segments of a ruptured pipe and for the thrust force at break location.

(2) Document GE procedure for performing the nonlinear time-history analysis of the ruptured pipe using the ANSYS computer program.

(3) Show compliance with ASME III, Equation (9) stress limit .;et by SRP 3.6.2 (MEB 3-1) for the piping between the containment isolation valves following a postulated pipe rupture.

(4) Provide justification for the 0.001 time step used by GE in the ANSYS time-history i

analysis.

(5) Show that GE methodology based on the simplifying assumption of no rotation of the thrust force at the pipe break is valid for predicting stresses in the containment piping.

(6) Show the use of the GE program, PDA, provides a satisfactory basis for selecting the size of the pipe whip restraint.

-iii- ,

GE-NE-123-E070-0493 l This report documents the following results of the sample analyses: l l

l (1) The postulated pipe break location that results in the highest stresses inside the containment is at the connection of the main steam pipe to RPV nozzle.

(2) The ASME'III, Equation (9) stresses in the containment area of the main steam pipe following a pipe rupture at the RPV nozzle are below the SRP 3.6.2 limit of 2.25 Sm, even with the followirg conservative assumptions: (a) the restraining effects of snubbers )

on main steam line are not considered; (b) the restraining effects of SRV branch lines are l not considered; (c) the lower pressure in main steam pipe immediately following a pipe  !

I rupture is not considered.  ;

(3) Decreasing the time step from 0.001 seconds to 0.0005 seconds has insignificant effect on results, proving convergence of the ANSYS solution with the GE analytical assumption of 0.001 seconds.

f (4) The maximum pipe stress in the containment area does not increase due to rotation of the thrust force at the pipe rupture location. This confirms that the GE nonlinear analysis based on no rotation of the thrust force provides accurate results.

(5) The GE computer program, PDA, provides a satisfactory basis for selecting the size of the pipe whip restraints.

1.0 INTRODUCTION

i This report presents the results of an analysis performed to evaluate the effects of a postulated ;

l circumferential pipe break at the connection of the ABWR main steam pipe to the Reactor Pressure Vessel (RPV) nozzle on the pipe stresses between the inboard and the outboard Main '

Steam Isolation Valves (MSIV). This postulated break was chosen for analysis because this break will create the maximum stress in the pipe between the containment isolation valves, since the M.S. pipe has the largest diameter (i.e. 28") compared with SRVDL's 10" and Feedwater's 12" size. l The analysis for the postulated main steam pipe break analysis presented in this report includes l forcing function calculations and the nonlinear dynamic analysis.

The result of the analysis show that the stresses i the j'pe between the containment isolation  !

valves meet SRP 3.6.2 stress limit (2.255m).

l 2.0 PIPE BREAK FORCING FUNCTION ANALYSIS 2.1 Description b

The steam Gows in the main steam nne from the RPV to the turbine during normal operation.

~

When a postulated pipe break occurs at the RPV nozzle safe end or at the first elbow down stream of the RPV nozzle, the steam flow in the main steam line suddenly reverses and flows back to the i break location. A decompression wave starts at the break location and propagates toward the turbine, creating force time histories on each main steam pipe segment.

In order to calculate the force time histories on each pipe segment, a modification in the Turbine Stop Valve Closure Force (TSFOR) calculation method is used. TSFOR is an Engineering Computer Program (ECP) used to calculate the pipe segment force time histories due to turbine stop valve closure event. The program is dearibed in NEDE-23789. The boundary condition of this program is modified to calculate the pipe segment force time histories due to the postulated pipe break of the main steam pipe at the RPV nozzle. t i

l Modifications to TSFOR and the procedures to calculate the force time histories are described in the following sections.

'I 2.2 Generation of Main Steam Pipe Break Input Data ,

The back flow of steam through the main steam piping can be computed by applying the break boundary condition at the main steam RPV nozzle _as shown below (Reference 1).

p/p0 = (2/(K+ 1))"(2K/K-1) = 0.30

<j > /C0 = (2/(K+ 1)) = 0.87

< rho >/(rho 0) = (2/(K+1))"(2/(K-1)) = 0.40 where, i

p = steam pressure at the break exit, psia p0 = stagnation pressure, psia

<j > = discharge velocity at the break exit, ft/sec l C0 = sonic velocity at the stagnation condition I

rho = steam density at the exit, Ibm /ft^3 rho 0 = stagnation density, ibm /ft'3 K = gas constant,1.3 for saturated steam.

l l

GE-NE-123-E070-0493 An executable program file, called MS-BRK, has been set up to calculate the pipe segment forces due to the postulated break. The method of analysis is the same as described in the ANS-58.2, Appendix A.

The MS-BRK program input is setup exactly the same as the TSFOR input which is described in NEDE-23789, Reference 4. The pipe break boundary condition computer input is calculated as described above. The input includes pipe inside diameter, flow rate, pressure, specinc volume, segment length, the friction factor and the gas constant.

The procedure defined in this paragraph for a main steam pipe break is not applicable for a break in the feedwater pipe. For piping systems containing water, force time histories due to a postult.ted pipe break are calculated using the methodologies provided in Section 6.2 and Apper. dix B of ANS 58.2 (Reference 2).

2.3 Calculation o! Input Force Time Histories at the Break Location Let the length of the first pipe segment with the break be L ft. The time for the pressure wave to travel through the first pipe segment is t1 = L/C, where C = sonic velocity in steam.

t1 = 0.0038 seconds For t < t1 F = PA = 533,671 lbs.

For t 1 t1 F = C TPA = 373,570 lbs.

W here P = 1,070 psi A = 498.4 in' CT = 0.7 The blowdown force time history shown in Figure A-1 is input at the pipe break location.

GE-NE-123-E070-0493 i

The determination of the steady state thrust coefficient, CT, is dependent on the fluid and the friction loss terms. .

l fUD = 2.5 (Based on representative values for previous BWR's CT = 0.7 (From Figure B-3 ANS 58.2, Appendix B, Reference 2)

The fUD value includes the friction from the pipe break to the turbine, plus the friction I

through hiSIV's and through the other three pipes from RPV. The overall fUD is > 2.5.

2.4 Analysis Steps 1

The following steps can be used to generate the pipe segment force time histories due to main steam pipe break at the nozzle safe-end.

!) Prepare the TSFOR01 input deck.

Create a PERhi file to sase force time histories. ,

2) Select the following file to run instead of TSFOR01 :

$$ SELECT FS0027/HLH/ hts-BRK-R i

3) Down load the time histories to PC (ASCII).  ;

~

4) Run hts-BRK-R to convert the force time histories to ANSYS input format.

5) Prepare the ANSYS input model.

6) RUN ANSYS. i Details of Steps 3 through 6 are included in ANSYS Analysis Procedures.

Bend radius of elbows is not considered in segment definition when calculating segment forces.

Where elbows exist, the segment extends to the tangent intersection point. This approximation f has proved valid when calculating segment forces due to other thermo-hydraulic loads such as t

3.0 ANSYS NON-LINEAR ANALYSIS  !

3.1 Analysis Model ,

The pipe break non-linear time history analysis can be performed by ANSYS program. The piping model is shown in Figure 1.

The selection of elements and nodes is the same as for the seismic and dynamic analysis of the pipe. The main steam guide located inside the drywell, which provides only lateral restraint, in the horizontal direction and in the vertical direction, is included in the model and is modeled as two spring elements. Snubbers, seismic restraints and branch piping are excluded from the model. This model simplification is generally conservative when estimating displacements of f the piping system since they would act as restraints to displacements.  !

In some cases a seismic support could be oriented such that following a pipe break, the restraint provided by the seismic support ccrid result in higher piping stresses. Therefore, the  ;

engineer should first review the seismic support design to determine whether seismic supports should be included in the ANSYS analysis model.

i The selection of the input are described as follows:

1 Analysis : KAN=4 Plastic pipe : use STIF 20 Plastic elbow: use STIF 60 .

Pipe whip restraint : use STIF 39 3.2 Analysis Time Step  ;

When performing the non-linear analysis, it is necessary to show the analysis time step is adequate to result in convergence. In order to show that the analysis time step of 0.001 seconds  :

is adequate, an analysis with time step of 0.0005 seconds has been performed. The results of the analysis are plotted in the figures listed below. Comparisons of the results between 0.001 seconds and 0.0005 seconds time step show that the differences are less than 3%. Therefore, l time step of 0.001 seconds can be used in the analysis.

. Since the analysis was based on the ANSYS option that assumes small displacements of the piping model, it is necessary to con 6rm the validity of the analysis iflarge displacements occur. The displacements from the terminal end Main Steam Break Structure (MSBS) analysis (using ANSYS) results show that the largest displacements and rotations occur at the break.

These rotations and displacements of the pipe at the break cause a change in the direction of the ' s thrust force at the break. To determine if the effects of this thrust direction change the stresses

~

in the pipe between the isolation valves, GE has performed time history analyses for both the original and displaced positions to confirm the validity of the small displacement assumption in ,

the non-linear time history analysis results.

Two cases of displaced analysis have been performed. In Case 1, the element at the break and the thrust force are rotated. In Case 2, the thrust force and the section of piping between the break location and the first pipe whip restraint are rotated. - ,

The results of the Case 1 analysis are shown in the following figures:

Figure 2B: Impact force at the pipe whip restraint. DT=0.001 sec (Included rotated blowdown angle)

The results of the Case 2 analysis are shown in the following 6gures:

(Included displaced elbow and broken pipe orientation)

The maximum stresses between the MSIV's do not increase due to the force direction change -

as result of the large displacements at the break location. This shows that the nonlinear analysis '

based on design location is acceptable. If the results from Case 1 and Case 2 did not closely i

agree with the design location, an acceptable alternative would be to use the large displacement option of the ANSYS program.

Allowable limit = 2.25 Sm

=41780 psi  :

i The maximum bending moment between the MSIV's will be developed about 0.075 second after the break. The decompressing wave travels at 1600 ft/sec. It has traveled a distance of 1600x0.075 = 120 ft when the maximum moment occurs. Therefore, the prest :tre between the MSIV at the time when the maximum bending moment is developed will be much less than normal operating pressure of 1050 psi. It is conservative to use 1050 psi to calculate the pressure stress.

Sp = PD/4t ,

5.0 CONCLUSION

S

1) The maximum combined stress in the pipe between the containment isolation valves is 39839 psi. This is belcw 2.25 Sm allowable limit (i.e.

41780 psi) as specined in SRP 3.6.2.

2) The maximum pipe stresses between the MSIV's do not increase due to the force direction change as result of the displacements at the break i location. This shows that the nonlinear analysis based on design location is ,

acceptable.

3) Calculated pipe whip restraint load by ANSYS is 670,000 lb. The PDA calculated peak restraint load is 666,727 lb. Both results are comparable.

Either PDA or ANSYS program is acceptable to be used for sizing pipe whip restraints.

l 5.1 Conservatisrn in the Analysis i I

Summary of conservative assumptions are as follows:  :

a) The main steam pipe snubbers are not considered. This is conservative I t

because the supports reduce pipe stresses between MSIV's. The support can  ;

absorb energy before failure if load is exceeded. i The branch pipes are not included in the model, which is conservative because the branch pipes act like restraints for the main steam pipe.

i b) Pressure stress at the normal operating condition is used in the load combination. This is conservative because the pressure in the pipe will be I reduced due to pipe break, i
