GENE-0000-0034-6469-01 R2-NP 1.0 Introduction 1.1 Description The dryer mast is used to support the conduit tubes for instrumentation sensor wires. The dryer mast includes a 4 inch tube which is connected to the dryer top hood through 3 stabilizer support brackets as shown in Figure 1-1. There are 12 conduit tubes, which are attached to the dryer mast through the dryer stiffening plates. These conduit tubes are used to protect Inconel alloy sensor wires of ((
)) for the strain gauges and ((
)) for the pressure gauges and accelerometers.
1.2 Scope The scope of this analysis is the dryer mast from dryer top hood connecting plate, 4" mast tube and all the conduit tubes for instrumentation sensors to the seal weld at the tube sealing cap. The RPV flange and the penetration bolt analyses are excluded from the scope of this analysis. The pressure boundary as shown in Figure 1-2 is the ASME Class 1. Per ASME Section III paragraph NB-3630(d)(1), for Class 1 piping of 1 in. nominal pipe size or less may be analyzed in accordance with the NC-3600 Class 2 component. The conduit tube below the seal header is not a pressure boundary.
Since the mast is considered as a continuation of the dryer, it is considered as an ASME Class component, and this analysis will show that the NC-3600 requirements are satisfied. The stabilizer support brackets and the supporting plates to support the conduit tubes are under the jurisdiction boundary of the ASME Section NF Code.
1.3 Purpose During operation, differential thermal expansion due to the dryer mast having a higher coefficient of thermal expansion than the reactor pressure vessel (RPV) induces the load in the dryer mast. Also pressure and steam flow velocities acting across the dryer mast, as well as seismic acceleration, act to increase the load and stress.
The 0.375" diameter conduit tubes and the 4"diameter mast tube are in tube schedule. However, these tubes are called piping in the ASME code. Because the purpose of this analysis is to show that these components meet the NC-3600 piping code requirement, the conduit tube is referred to as a pipe throughout this report.
The purpose of this report is to analytically demonstrate the structural integrity of the dryer mast design including conduit pipes meeting NC-3600 design requirements. The load combinations for the design requirements and operating condition include gravitational, thermal, pressure, steady state drag forces, fluid-induced vibration, and earthquake loads.

GENE-0000-0034-6469-01 R2-NP 2.0 Conclusions and Interface Requirements ANSYS finite element code and PISYS07D were used to evaluate the dynamic and static response of the dryer mast. ANSYS was used to evaluate the response of the stabilizer supports and PISYS07D was used for the piping system. The output from PISYSO7D program with ANSI713D program is used to calculate stresses in accordance with the ASME NC-3600 Piping code. Six load combinations were evaluated for each component as described in Table B-I.
2.1 Code Compliance Results of the analysis in Appendix C show that the requirements (equations) of ASME Section III Class II Components and NC-3600 have been met for all the pipe components.
A summary of pipe stresses for the dryer mast and conduit is presented in Appendix D. Two tables are provided for each section. The first table tabulates the summary of stresses in the ANSI7 joint input sequence. The second table arranges the stress ratios from the highest stress to the lowest stress value Within the scope of this report, design of the dryer mast meets the requirements of ASME Section III NF-3600. The stress ratios for each location are summarized in Appendix C. The dryer mast pipe, conduit pipes, and stabilizer supports have adequate margins for primary and secondary stresses.
2.2 Design Margin The maximum stress ratios (max calculated stress/allowable) for each load combination for the various component types are tabulated below from Appendix D. Load combination and acceptance criteria are presented in Table B-I Appendix B.

GENE-0000-0034-6469-01 R2-NP 2.3 Interface Requirements 2.3.1 Penetration Bolt Force and Moments The external forces and moments on top of the penetration bolt are summarized in Appendix F-1.
These external forces and moments are provided to the responsible engineering group to address the stresses in the penetration bolt and RPV flange.
Figure 2.3 presents the interface for the conduit pipe with RPV top flange including penetration bolt assembly. The forces and moments for the RPV top flange are calculated for the location of node 32 in Figure 2.3. Nodes 25 and 26 are for the coupling tube location in Figure 2.3.
2.3.2 Conduit supports As shown in Figure 1-1, these conduit pipes are laterally supported by the plates, which are welded to the 4" mast tube. Due to thermal expansion of the conduit from the top of the penetration bolt, the support plate should allow the conduit to move in the axial direction. Refer to the Figure A-1 in Appendix A, which shows that the conduit tube at the bottom should have a ((
)) to absorb the thermal movement, from node 1 to 2N in this figure.
2.3.3 Dryer top hood support bolt loads Refer to Figures A-2 and A-3 for the node number in the dryer mast model. All the support loads are tabulated in Appendix F-2.

4.0 Input Data The geometries of the dryer mast design with conduit pipe were obtained from the mast drawings.
Page 6 of 61
GENE-0000-0034-6469-01 R2-NP 4.1 Mechanical Properties The dryer mast, conduit pipes, and stiffening plates are composed of stainless steel alloy SA240, 304 L. The material properties for SA240, 304 L are presented in Tables 4.1. The dimensional properties of the piping system are presented in Table 4.2.
It should be mentioned that the plate material for the 4 inch dryer mast is specified as stainless steel alloy ASTM A312 type 304 L. This material is identical with the same heat treatment conditions as SA240,304 L.
4.2 Dryer Mast Configurations ANSYS finite element model and PISYS07D isometric joint diagrams showing the piping configurations are found in Appendix A.
4.3 Operating and Design Temperatures The operating and design temperatures for the dryer mast design are 550 F and 575 F, respectively.
4.4 Loads The static and dynamic loads acting on the dryer mast design are defined in Table 4.3.
4.4.1 Design Pressure and Acoustic Pressure The design pressure load acting on the dryer mast is 1250 psi (see Table 4.2). The acoustic differential pressure across the conduit and dyer mast piping is negligible. Also the peak frequency of the acoustic excitation force is significantly higher than the first mode frequency of the conduit pipe ((
)). Therefore, the acoustic pressure associated with FIV load is not considered in this analysis.
4.4.2 Dead Weight The dead weight loads acting on the dryer mast are defined in Table 4.2. The weight of conduit and dryer mast pipes and instrumentation wires are shown in Table 4.2.
4.4.3 Drag Force and Vortex Shedding Page 7 of 61
GENE-0000-0034-6469-01 R2-NP 1]
The flow over the cylinder creates unsteady Strouhal and buffeting lifting force (FL') perpendicular to the flow direction and Strouhal and buffeting drag force (FD') in the direction of the flow. These unsteady forces are a small fraction of the drag force.
The first natural frequency of the dryer mast is ((
)), which is significantly lower than the vortex shedding frequency at the top of the dryer. Therefore, the flow velocity does not have enough energy to cause significant fatigue damage.
Page 8 of 61
GENE-0000-0034-6469-01 R2-NP 4.4.4 Seismic Load The seismic coefficients are ((
)) in the horizontal directions and ((
)) in the vertical direction for the operating Base Earthquake (OBE). The seismic coefficients for safety shutdown (SSE) are twice of the OBE.
4.4.5 Thermal Expansion Load During operation, differential thermal expansion due to the dryer mast having a higher coefficient of thermal expansion than the reactor pressure vessel (RPV) induces the load in the dryer mast. Thermal expansion load is calculated from 75 deg. F-to design temperature of 575 deg. F. The relative anchor.
displacements between the top hood of the dryer and the RPV flange are also included in the analysis.
5.0 Load Combinations and Acceptance Criteria The load combination and acceptance criteria for the dryer mast design are shown in Table B-I Appendix B.

6.2 Analysis ANSYS finite element code and PISYS07D were used to calculate the dynamic and static response of the dryer mast. ANSYS was used to evaluate the response of the stabilizer supports and PISYS07D was used for the piping system. The output from PISYS07D program with ANSI713D program is used to calculate stresses in accordance with ASME NC-3600 code. Six load combinations were evaluated for each component as described in Table b-I Appendix B.
6.3 Computer Programs The computer programs used in the piping stress analysis are described below. All of these programs meet GE Quality Control Standards. All programs have been approved for production use after independent review and verification. Any changes to these programs require verification and approval in accordance with GE Quality Assurance Program. The programs listed below operate on a DEC/Alpha Station running DEC UNIX.
Page 10 of 61
GENE-0000-0034-6469-01 R2-NP 6.3.1 PISYS07D GE's proprietary computer program, PISYS07D, was used to calculate the response of the piping system to all of the static and dynamic loads.
6.3.2 ANSI713D The output from the PISYS07D program was evaluated by another GE proprietary computer program, ANSI713D. The ANSI713D program calculates stresses and cumulative usage factors, as applicable, for Class 1, 2 and 3 and ASME B31.1 piping components in accordance with applicable codes. This program also calculates combined loads on piping equipment and compares them with the allowable loads where applicable.
7.0 Evaluation of Results 7.1 Modal Analysis Results ANSYS finite element modal analysis is presented in Appendix E. Modal Analysis results indicate that the first bending mode occurs at ((
)). This bending mode is associated with the bending of conduit pipe at the mast dryer pipe attached area.
7.2 Stress Analysis Results 7.2.1 Piping Stress Analysis Results 7.2.1.1 Pressure Design The minimum wall requirement of NC-3133.8 for the 0.375 inch tube and 0.568 inch coupling tube under external pressure is determined in accordance with Fig. NC-3133.8-1. Based on this figure, the minimum wall tube and coupling wall tube under external pressure can be calculated below.
Page 11 of 61
GENE-0000-0034-6469-01 R2-NP The calculated required minimum pipe wall and nominal pipe wall values are provided in Table 4.2. It can be seen that the minimum thickness for these components are greater than the calculated minimum wall thickness. Thus the code requirement has been met.
7.2.1.2 Stress Analysis Results The piping was analyzed in accordance with the requirements of ASME NC-3600 Piping Code by the PISYS computer programs. This program produces structural solutions based on the applied loading, inputs, and modeling techniques described in the previous sections. The solutions are post-processed to be compared to the material allowable values. The interface loads (forces and moments) acting on the pipe are also generated.
The detailed stress analysis results meeting NC-3650 equations are listed in Appendix C. It is noted that the pressure stresses listed for each component are the longitudinal stress in the Code equations.
The pressure acting on the conduit is external pressure. Because the stress analysis from the NC-3600 equations uses an absolute sum, only positive values are listed. A summary of pipe stresses for the dryer mast and conduit are presented in Appendix D. Two tables are provided for each section. The first table tabulates the summary of stresses in the ANSI7 joint input sequence. The second table arranges the stress ratios from the highest stress to the lowest stress value. The external forces and moments on the top flange and the reaction loads at the dryer interface are summarized in Appendix F.
7.2.2 Stabilizer Bracket Stress Analysis Results The results of stress analysis for the stabilizer brackets are presented in Appendix G. The node number for theses brackets are presented in Figures A-2 and A-3.
7.2.2 Weld Stress Analysis Results 7.2.2.1 Support Bracket The support bracket is ((
)) and it is welded to the dryer mast tube (4 inch diameter) using a ((
]J weld. The weld strength capability is calculated as:
Page 12 of 61
GENE-0000-0034-6469-01 R2-NP Using the minimum weld shear strength of 30X0.3= 9 ksi with the combined bending and shear stress results in load capability of ((
)) for each side of the bracket. Each side of the bracket supports six conduit pipes. The actual loads for these six conduit pips at support bracket are significantly less than ((
)). Therefore, there is significant margin of safety for the welded region.

Using the minimum weld shear strength of 30x0.3= 9 ksi, there is significant margin of safety for the welded region 7.2.2.3 Short and Long Gussets The stresses for the short and long gussets are very small compared to weld strength capability.
7.2.3 Support Bracket Bolt Stress Analysis Results The support brackets are used to attach the dryer mast to the dryer using ((
)) bolts made of the ASTM A479, 304 L. The tensile strength capability of the ((
)) bolts in each bracket is:
The loads for the support bracket attached to the dryer are presented in Appendix F. These loads and combined resultant loads are significantly less than the tension capability of ((
)).

There are two types of elements that the PISYS computer program uses to form the pipe model. One is the straight or tangent element and the other is a planar bend element. Each element has local coordinate axes that orient the element in the global coordinate system and identify force and moment components at a joint with respect to element axis. Joint displacements and rotations are in global coordinates. The convention for the orientation of local axes is as follows:
- 1. Tangent elements parallel to the global Y-axis (vertical axis) have their local B-axis diverted to and in the same direction as the global Z-axis.
Page 17 of 61
GENE-0000-0034-6469-01 R2-NP
- 2.
Tangent Elements not parallel to the global Y-axis have their local B-axis contained in a vertical (global) plane such that local B-axis projects positively on the positive global Y-axis.
- 3.
For bend elements, the local B-axis is directed positively toward and intersects the center of curvature of the bend (i.e., radius vector).
- 4. The local A-axis is tangent to the arc ofthe bend or straight element and is directed positively from the FROM joint to the TO joint.
