WESTINGHOUSE ElECTRIC COMPANY LLC Calculation Nee N umbmr Revision P CN-RCDA0568 1 1 5 1.0 Introduction
1.1 BACKGROUND
I PURPOSE The purpose of this calculation is to perform a plastic analysis of the Point Beach Unit 2 Reactor Coolant Main Loop Piping, for a postulated downward vertical displacement of up to 6.5 inches at the Reactor Vessel nozzles. This postulated displacement Is conjectured to occur due to a drop of the reactor vessel head onto the reactor vessel during installation or removal. It should be noted that the 6.5-Inch displacement value is not demonstrated to be the actual displacement that would be caused due to a reactor vessel head drop. It Is a conjectured value, and the purpose of this analysis Is to analyze the effects of such a displacement.
It should be noted that this Is not a rigorous ASME Code analysis. Allowable limits, which are discussed In Section 4 and obtained from the ASME Code Appendix F. are created as reasonable limits that can be used to investigate the behavior of the Hot and Cold leg piping due to this postulated displacement.
This calculation note was prepared ascording to Westinghouse Procedure WP 4.5.
1.2 LIMITS OF APPLICABILITY This Calculation Note Is applicable to Point Beach Unit 2. It Is also likely that the calculation Is applicable to Point Beach Unit 1, however, Insufficient references have been included In this document to confirm applicability.

WESTINGHOUSE ELECTRIC COMPANY LLC Cculal Note NumberRevsion Page CN-RCDA05-68 1 6 2.0 Summary of Results and Conclusions The results of this analysis show that the computed maximum Stress Intensity are less than the allowable values that are listed InSection 4. Therefore, It can be concluded that the structural Integrity of the Point Beach Unit 2 Hot and Cold Leg piping is maintained after the postulated 6.5-inch displacement due to a Reactor Vessel Head drop.
The following Table summarizes the Stress and Strain results. The explanation of the ANSYS runs used to obtain these results can be found In Section 6. The allowable values listed In the Table below are discussed In Section 4. As this Table Indicates, the cold leg Is more severely stressed than the hot leg and therefore controlling. Reviewing the results (for 4' case) for maximum versus minimum assumed properties Indicates that the stress ratio Is essentially the same. Therefore, the 6.5 Inch displacement case Is only evaluated for the cold leg minimum property case. It Is noted that the results for the 6.5 Inch displacement case are well below the 0.90Su maximum stress limit. It can Ibe seen from Table 2-1 that the 4 Inch drop displacement results are less than the more conservative general membrane stress limit of 0.70Su.
Therefore, It Is judged that results demonstrate compliance with the Intent of the ASME Appendix F limits.

WESTINGHOUSE ELECTRIC COMPANY LLC Calculation NoteNumbRevision Page CN-RCDA-05.68 1 1 7 3.0 Assumptions and Open Items 3.1 DISCUSSION OF MAJOR ASSUMPTIONS The following assumptions are used Inthis Calculation Note.
- 1. The auxiliary piping is assumed to offer minimum vertical constraint. This Is confirmed by review of References 3 and 4. The only potential restraint Is the whip restraint structure shown in Reference it (Section D), but this offers only limited restraint of lateral deflection for the cold leg which Is not applicable to this problem.
- 2. The applied displacement Is assumed to be a static vertical displacement at the reactor vessel nozze supports. It Is also assumed that the dynamic effects from the drop will not significantly effect the damage assessment and the maximum stresses that are obtained from this model. This Is a reasonable assumption given this is Intended to be an assessment of the piping integrity.
- 3. The finite element model end points are assumed to be completely fixed except for the applied displacement. These points Include for hot leg: the safe-end region of the reactor vessel outlet nozzle and steam generator inlet nozzle and for the cold leg: the reactor vessel Inlet nozzle and the reactor coolant pump outlet nozzle. This is conservative with respect to the prediction of the maximum stresses.
3.2 OPEN ITEMS This Calculation Note contains no Open Items.

WESTINGHOUSE ELECTRIC COMPANY LLC Caicutaldon Note Number Revision Page CN-RCDA-05-68 1 8 4.0 Acceptance Criteria The following Acceptance Criteria aire reasonable limits that can be used to measure the behavior and structural integrity of the Hot and Cold legs due to the postulated displacement.
These Acceptance Criteria are not to be taken as a full ASME Code analysis.
Section 1II,Appendix F, paragraph F-1340, of the 1998 Edition of the ASME Code (Reference 5) defines allowable limits when using plastic system analysis. An acceptable method of component analysis Is plastic analysis, which has been used Inthis case. The limits for plastic component analysis are provided In F1 341.2.
The following primary stress limits are provided:
(a) the general primary membrane stress intensity Pm shall not exceed the greater of 0.7OSu and Sy + (1/3(Su-Sy). For the selected controlling case In which Sy = 30 ksl and Su = 70 ksl, the 0.70Su allowable (49 ksl) controls.
(b) the maximum primary stress Intensity at any location shall not exceed O.90Su.
(c) the average primary shear across a section loaded In pure shear shall not exceed OA2Su.
Some interpretation Is required to properly assign the applicable allowable to a specific finite element derived stress. First, It Is clear that the shear limit (c) Is not applicable since the loading is bending controlled and not pure shear. The general primary membrane stress Intensity (a)Is a conservative limit to consider. However, this limit Is applicable to the average stress across the pipe cross-section, such as would occur from an axial load or a pressure load. For this case, the average stress across the pipe section Is Insignificant as both pressure and axial loads are Insignificant. The maximum primary stress Intensity at any location, needs to be defined based on the Intent of a primary stress. Per NB-3213.8, t Primary stress Is any normal or shear stress developed by an Imposed loading which Is necessary to satisfy the laws of equilibrium of external and Internal forces and mornents... Primary stress Is divided into general and local categories... (a) general membrane stress In a circular cylindrical ... shell due to Internal pressure'. Further, per NB-3213.6, 'Membrane stress Is the component of normal stress which Is uniformly distributed and equal to the average value of stress across the thickness of the section under consideration3 . In this case, the section Is the entire pipe cross-section, since the structural Integrity of the pipe is dependent on the entire section not a local" section through the wall at a particular circumferential angle.
The maximum stress Intensity provided by the finite element analysis reflects the membrane and bending stress obtained for the pipe section. This is a product of the beam formulation used in the pipe ernents. In addition, the elbow element has local stress intensfcation factors which are applied to account the local, through-wall bending effects which occur In an elbow.
The maximum stress intensity from pipe and elbow elements then reflect stresses which are very similar in intent to the maximum primary stresses referred to in F-1341.2(b). Use of any stress more localized than this value would only be objectionable from a fatigue standpoint and therefore the membrane plus bending stress Intensity from the finite element results is the only stress which could be applied to the 0.'9OSu stress limit for piping elements.

[ICalculaon NoteNumber Revision Page CN-RCDA5-68l 10 6.0 Calculations 6.1 METHOD DISCUSSION This analysis is performed to determine the effect of a 4 and 6.5-Inch vertical displacement applied on the reactor vessel nozzle ends of the Point Beach Unit 2 Hot and Cold leg piping, due to a reactor vessel head drop. The analysis Is done using relatively simple finite element models of the Hot Leg and Cold Leg, including non-linear material properties. The displacement Is assumed to be applied as a vertical static displacement at the reactor vessel nozzle supports.
The Hot Leg pipe is modeled as a 13-foot (based on shop spool piece drawings) straight horizontal run from the vessel outlet nozzle to the steam generator, Including the Inlet elbow.
The cold leg pipe Is modeled as a 26-degree horizontal elbow attached to the vessel inlet nozzle with a 9.5-foot (based on shop spool piece drawings) straight run to the reactor coolant pump outlet nozzle.
For each pipe, two ANSYS runs are made: one which assumes lower-bound values of Yield Strength and Ultimate Strength and another that assumes upper-bound values., Based on the results from the 4 Inch analysis, the 6.5 Inch case is analyzed only for the cold leg, minimum properties case (maximum and minimum property cases yield essentially the same results).
The intent of considering these two material strength cases Is only to bound the effect of mechanical strength. The plastic material behavior is characterized considering kinematic strain hardening.
The pipe Is modeled using the ANSYS PIPE20 and PIPE60 elements. The PIPE20 element is a plastic straight pipe element and the PIPE60 element Is a plastic pipe elbow element. These elements are sufficient to obtain an assessment of the general maximum strain (and stress) level In the pipe for the given loadings. Some higher strains (and stresses) could occur locally at discontinuities not Included in the model (due to strain concentration), but these would only be a concern for fatigue type cracking or small local surface cracks.
The critical result obtained from the analysis is the maximum stress Intensity for comparison to the ASME Code Section III, Appendix F (Reference 5), which provides a limit of 0.9S, for Maximum Primary Stress (see Section 4 for more details on the allowable).

WESTINGHOUSE ELECTRIC COMPANY LLC i NoteNumber Revislon Page lCN-RCDA0568 llI 11 I 6.2 INPUT A vertical downward displacement of four and 6.5 Inches is applied as a static load In the ANSYS model at the reactor vessel nozzle ends of the Hot and Cold leg piping. The steam generator (hot leg) and reactor coolant pump (cold leg) nozzles are assumed to be fixed points In the model.
6.2.1 Material Properties As mentioned previously, Lower- and Upper-bound material properties are chosen for Input to this analysis to bound the effect of mechanical strength. The straight section of the Hot and Cold Leg pipes are constructed from ASTM A-376 TP316, and the Hot and Cold Leg elbows are constructed from ASTM A-351 CF8M 4Reference 8).
- 1. Upper bound yield and tensile strength (labeled as Maximum Properties)
Sy = 40 ksl, S, = 90 ksl.
- 2. Lower bound yield and tensile strength (labeled as Minimum Properties)
S. = 30 ksl, S, = 70 ksi.
Material Properties from Reference 9 were examined for the above mentioned materials. It was found that ASTM A-376 TP316 (SA-376 TP316) has a Yield Strength of 30 ksl and an Ultimate Strength of 75 ksi at 100F. ASTM A-351 CF8M (SA-351 CF8M) was found to have a Yield Strength of 30 ksl and an Ultimate Strength of 70 ksi at 1000F. Therefore, the Minimum Properties case most closely models the true properties of the Hot and Cold Leg piping elbows, and Is slightly conservative with respect to the Hot and Cold Leg straight pipe sections.
Additionally, a Young's Modulus of 28.3x106 psi (Reference 9)and a Poisson's Ratio of 0.31 are used In the ANSYS analysis.
