~ R. Hammond The design for the ES-3100 containment vessel (CV) is evaluated for compliance with ASME Code,Section III structural design rules using bounding pressure loads and load requirements from the U.S. Code of Federal Register. Since the requirements are identical, the vessel is evaluated under both subsection NB in Section III, Division 1 and subsection WB in Division 3 of Section III of the ASME Boiler & Pressure Vessel Code. Traditionally, containment vessels from Type B packages have been evaluated using subsection NB, although such vessels are not clearly within the scope of NB. The new Division 3 of Section III explicitly includes Type B packages.

ASSUMPTIONS MADE Calculations are based on geometry and specifications from referenced drawings.

Results are rounded to significant figures although more digits may be retained in intermediate calculations.

Operating conditions must remain within the bounds of 200 psig internal pressure, 21. 7 psig external pressure, and 400°F.

IDENTIFICATION OF COMPUTER CALCULATION Computer Type: Dell PC with Intel Core' 2 Duo CPU E8400@ 3.00 GHz. 2.99 GHz using the Microsoft Windows XP Professional operating system Version 2.002, with Service Pack 3..

Computer Program Name, Revision, Verification, Applicability: Program is ANSYS Workbench vl2. l.

Verification per the Y-12 Software Quality Assurance program was by running example programs with known solutions. Hand calculations were used to confirm results. The program is applicable to linear elastic solutions for bodies of revolution as needed here.

METHODS TO BE USED The finite element method was used to determine the response of the CV components to gravity, gasket seating load, and internal pressure. External pressure resistance of the cylindrical shell was evaluated following Code rules. The finite element results also served to demonstrate the external pressure resistance of the lid and bottom of the CV. Buttress threads used to restrain the lid are evaluated by a method derived from an accepted way of determining the strength of standard threads.

Since stability and buckling are not issues, these flat heads were evaluated for resistance to internal pressure only. They can resist the design external pressure by linearity.

The maximum acceptable external pressure in this case is Pa= 4B/3(DJT) = 110 psig.

This allowable value exceeds the design external pressure (21. 7 psig) and the shell is acceptable.

This is the maximum acceptable compressive stress limited by axial buckling. The maximum external pressure applied to the axial cross section of the CV at 400°F can be derived using nominal values from:

NB-3200 (WB-3200) DESIGN BY ANALYSIS An axisymmetric finite element model was constructed from the solid model used to generate the referenced drawings of the CV body, the sealing lid, the closure nut, and the O-rings. Lines are introduced, cutting across the sealing lid and the body of the vessel and slicing the model into parts. The lines are used to contro 1 the placement of pressure load or to allow display of stress along the line ( so-called stress classification lines, or SCLs). Up to two loading conditions in addition to gravity were applied to each model per Section III NB or WB requirements: gasket seating and internal pressure. Load Case 1 combines gravity with gasket seating at ambient temperature. Load Case 2 combines gravity and gasket seating with internal pressure at 400°F.

Gasket Load Two concentric O-rings are specified to provide a redundant and testable seal. Per Drawing M2E801580A013, each O-ring has a 0.139-in. nominal cross-section diameter and is specified to have a 70 +/- 5 Shore A durometer hardness reading. The O-ring manufacturer's catalog Ref. 8 (Parker, P. 2-12) gives ranges of distributed force required to compress 0.139-in. O-rings. The O-ring grooves cut into the flange surface are specified to be 0.114-in. deep (ref. Detail E, Drawing M2E801580A012). The lid is expected to be pressed down, so contact is metal-to-metal. Then the O-rings will be compressed.

0.139in.-0.114in. xlO0 0 / = lS.0 o; 0.139 in.

The maximum distributed force required to compress a 70 hardness O-ring 20% is 30 lb/in. on the Parker chart. The maximum distributed force to compress a 70 hardness O-ring 10% is 14.5 lb/in. Linear interpolation to 18% compression yields 27 lb/in.

The O-rings are m9deled in place with flat s1,1rfaces where they press against the sealing lid abovy and the bottoms of the groves below. The lateral dimensions of the top and bottom flat regions were obtained from the solid model used to produce drawing of Parts M2E801580A013-1 and -2 and are listed in the following table.

The pressure equivalent to 27 lb/in. is 27 lb/in/(0.0600237 in.)= 449.822 psi and rounded to 450 psi with two significant figures. In the same way, equivalent pressures are calculated for each of the surfaces. These pressures are then applied to the finite element model along the respective surfaces and oriented to separate the flange surfaces.

Load Case 1, Gasket Seating, applied gravity and the equivalent gasket seating pressure to the model. The model was supported from a point at the top of the closure nut to avoid excess restraint and especially to avoid a reaction that would reduce deformation or stress internal to the vessel. The computer input is prepared interactively by the ANSYS Workbench program, so there is no input deck. All pertinent details for Case 1, however, are shown in Attachment A along with selected graphical output.

The loads applied in Load Case 1 are trivial. The maximum calculated stress intensity is shown in Figs. 1 7 and 21 in Attachment A. Focus is on the upper joint, because the gasket loads affect only that region.

Although even the maximum stress intensity is low relative to the basic allowable stresses for the materials, it is located in the threads and the ASME Code considers bolting separately from the rest of the pressure retaining boundary. Code compliance is also trivial for Load Case 1; the Code tests subdivide the computer results but the sum is less than the allowable for any of the subdivisions.

Load Case 2 adds a bounding value for internal pressure of 200 psig to gravity and the equivalent pressures representing gasket seating. The pressure is applied on the interior surfaces of the CV body and the sealing lid up to the radius of the outer edge of the inner O-ring groove. A vertical slice through the sealing lid at the outer radius of the inner O-ring groove was included for this purpose. Input details and results are shown in Attachment B. The surfaces around the inner O-ring where the internal pressure was applied are shown in Attachment B, Fig. 9. Material properties at 400°F are used in this case. Figure 10 in Attachment B for Load Case 2 locates the maximum stress intensity in the threads between the closure nut and the top of the CV body. Away from the threads, the highest stress intensity is located near the bottom of the CV body as shown in Fig. 20 in Attachment B. This location is near where bending is induced by pressure across the flat bottom as indicated by Fig. 19 in Attachment B. Stress intensity is nearly as high at the neck just below the threads in the CV body as shown in Attachment B, Fig. 15.

Calculated deformations at the inner O-ring are plotted in Fig. 28 in Attachment B. The difference in deformations between the bottom of the inner O-ring groove and the surface of the sealing lid directly above is 0.000122 in. - -0.002727 in.= 0.0028 in. due to the internal pressure of 200 psi and the reaction of the O-rings. From Fig. 23 from Attachment A, the ba.seline deflection ( due to tl)e force required to compress the rings) across the inner O-ring groove is 0.000456 in. - -0.001005 in.= 0.0015 in. Since preload of the closure nut will eliminate the deflection during gasket seating, only 0.0028 in. - 0.0015 in.=

0.0014 in. of the final deflection is due to internal pressure alone.

NB-3 221.1 (WB-3 221.1) General Primary Membrane Stress Intensity General primary membrane stress intensity is limited to the basic allowable stress intensity at temperature (i.e., 16,700 psi up to 300°F and 15,800 psi at 400°F) in the CV body. The general primary membrane stress intensity is based on stresses averaged across the thickness of a section, away from local transition regions such as threads, changes of thickness, or the joints between side and top or bottom. The highest calculated stress intensity away from threads is a peak value of2001 psi for Load Case 1 (see Figs. 17, 21, and 26 in Attachment A). Average or membrane stress is always less than peak stress, so the CV is acceptable for the gasket seating load.

Figure 16 in Attachment B is a close look at the cylindrical section at the mid-plane of the CV body side.

The maximum stress intensity away from thickened sections is 5362 psi. As a check, the average elastic

Bloom stresses in the middle of the cylindrical side of the vessel are easily calculated from equilibrium.

Section III of the ASME Code provides values in Nonmandatory Appendix A [Ref. 1 (Appendix)]. The tolerance on critical dimensions is +/-0.01 in. and is taken into consideration to calculate maximum values of stress intensity.

The value calculated from the finite element model is based on nominal dimensions. Amplifying the finite element result by the ratio of nominal wall thickness to minimum wall thickness gives 5362 psi (0.10 in./0.09 in)= 5958 psi. The difference, 5958 psi/5768 psi= 1.03, is just 3% higher than the value calculated using the Code formula. This comparison confirms the computer solution for the cylindrical section.

Figure 22 in Attachment B shows the radial stress at the center of the CV body bottom. The values vary linearly from -11,676 psi at the top surface to 13,985 psi at the bottom surface. The membrane radial stress is equal to the mean of the top and bottom values along the centerline or [13,985 psi+

(-11,676 psi)]/2 = 1154 psi. Hoop stress is zero at the center axis, and the vertical stress varies between

-200 psi at the inner surface to O psi at the outer surface by equilibrium. The membrane or average stress intensity is less than 1154 psi-(-200 psi)= 1354 psi. The allowable membrane stress intensity is 15,800 psi at 400°F, so the CV bottom is acceptable. Since all of the calculated membrane stress intensities are less than the allowable stress, all of the CV body meets the Code limit on membrane stress intensity.

Similarly, from Fig. 23 in Attachment B, there is a compressive radial membrane stress of about 3000 psi at the center of the sealing lid. The allowable membrane stress intensity for the lid material is 18,600 psi at 400°F, so the lid is acceptable.

C NB-3221.2 (WB-3221.2) Local Membrane Stress Intensity SHEET 10 of 15 Local membrane stress intensity is the average stress across the thickness of a cross section at junctions such as between the side and bottom of the CV, or the side and the transition to the flange area near the top of the CV, or changes in thickness like the neck below the threads. The allowable value of this stress component is 1.5 times the basic allowable stress or 1.5(15,800 psi)= 23,700 psi at 400°F in the CV body.

Figures 15, 17, 18, 19, 20, and 24 from Attachment B show that the peak values of stress intensity at junctions and transitions in the CV body are at most 16,730 psi, which is below the allowable amount, and the CV body is acceptable. Bending is present at all of these locations, and since local membrane stress excludes the bending component, a direct comparison of calculated values is conservative.

NB-3221.3 (WB-3221.4) Primary Membrane plus Primary Bending Stress Intensity The allowable stress intensity for local primary membrane stress plus primary bending stress is also 1.5 times the basic allowable stress intensity; therefore, the calculated stress intensities shown in Figs. 15, 17, 18, 19, 20, and 24 are still acceptable. The stress intensity calculated at the CV bottom axis, shown in Fig. 25 in Attachment B, is also acceptable, as is the stress intensity at the sealing lid center in Fig. 26.

As a check on the computer calculations, Figs. 21 and 22 in Attachment B show the normal radial stresses along the central axis and the outer edge of the CV bottom. It is clear from these figures that the distribution is primarily due to bending. The highest principal stress is 13,985 psi located at the lower, outer surface at the central axis of the bottom. Since there is no vertical stress at this point and no hoop stress, the stress intensity is equal to 13,985 psi - 0 psi= 13,985 psi. This value is essentially the same as the value of stress intensity calculated by the program, 13,984 psi, which is shown in Fig. 25.

The stress in the bottom cover is complicated by attachment to the side, but bending stress at the center can be checked by bounding stress between simple support and fixed support around the outside edge. From the_ Code Appendix [Ref. 1 (Appendix)]:

A-5212 Radial bending stress at center (r = 0) and top or bottom surface (x = t/2)

This equation is based on a simply supported outer edge. For a fixed edge, the stress at the same point using Ref. 9 (Roark) (Table 24, Case 1 Ob) is:

G. Bloom values, as expected.

The sealing lid is much thicker than the CV bottom except at the center. The calculated stress intensity at the sealing lid center axis, 3152 psi, shown in Fig. 26 in Attachment B, is less than 1.5 times the basic allowable stress intensity for the sealing lid, 1.5(18,600 psi)= 27,900 psi.

WB-3222.6 Primary Plus Secondary Stress Intensity The calculated stress intensities all include secondary stress effects. Notice, for example, in Fig. 21 in Attachment B that the gradient in radial normal stress is greater at the top surface of the CV bottom than at the bottom due to the intensification by the concave transition between the bottom and the side of the CV body. These intensified stresses have been conservatively included when comparing to allowable stress intensity-excluding secondary stresses. Since the secondary stress limit is three times the basic allowable stress intensity, the calculated stresses are clearly acceptable.

NB-3222.3 (WB-3222.7) Expansion Stress Intensity Expansion stress intensity is undefined but can be bounded. The largest temperature range possible for the CV is between -40°F (the minimum temperature specified in 10CFR71) and 400°F (defined here).

Suppose a tendril maintains a temperature of -40°F while the surrounding material is heated to 400°F. The result is a 440°F temperature difference across a sharp boundary-an infinite gradient. The stress in the tendril would be a= E a<_40)_400 440 ° F. Conservatively, Eis the cold modulus of elasticity of the weaker CV body material, i.e., 28,800,000 psi by interpolation from Table TM-1 in Code Section II. The temperature at the midpoint of the range from -40°F to 400°F is 180°F, and the instantaneous linear thermal expansion coefficient, a, at that temperature is 9.24 x 10-6 in/in/°F interpolated from Table TE-1 in Code Section II. The bounding expansion stress is 117,000 psi, which is a fictitious elastic stress per the Code. Add te5 this the highest stress frotn the CV and lid models multiplied by an intensification factor of 2, because the finite element program may extrapolate to the surface too simplistically, so that 117,000 psi

+ 2 (16,730 psi)= 150,000 psi. The alternating stress is half this value, or 75,000 psi. The allowable number of cycles for this alternating stress per Fig. I-9.2 in Code Mandatory Appendix I is 3,000. The vessel should be acceptable for almost a hundred years with 30 swings through the full temperature range per year; a severe transportation accident, however, should be counted as two cycles, one for impact and one for fire.

NB-3230 (WB-3230) STRESS LIMITS FOR BOLTS NB-3232.1 (WB-3232.1) Average Stress SHEET 12 of 15 ond

. Bloom The CV threaded joint is treated as a closure bolt. Special consideration is given to the neck above the lid.

Based on dimensions from Drawing M2E8015 80AO 12, the internal pressure applied to the maximum outer diameter of the inner 0-ring groove produces an axial force of FP =200psi(n/4) (5.624in.+0.010in.)2 =4986lb.

The force due to gasket seating is Wm 2 = 27 lb.I in.n [(5.359 in.+ 0.139 in.)+ (5.859 in.+ 0.139 in.)]= 975 lb.

The combined force is 4986 lb+ 975 lb= 5961 lb. The minimum area at the neck in the CV body just below the threads is AN = n I 4[(7.50in. -0.0lin.)2 -(6.85in. + 0.0lin. + 2{0.09in. + O.Olin.}) 2 ] = 4.9lin 2.

The average stress due to the pressure plus gasket seating at this neck is 5961 psi/4.91 in2 = 1214 psi. This stress must be less than twice the basic allowable stress for bolting, a round-about way of saying two-thirds of yield. From Table Y-1 from Ref. 10 (Section 11) the yield strength of SA-182 F304L material at 400°F is 17,500 psi. Two-thirds of this yield strength is 11,700 psi. This comfortably exceeds the average stress.

NB-3232.2 (WB-3232.3) Maximum Stress Maximum service stress in a bolt including bending stress but excluding stress concentrations may be three times the basic allowable stress for bolts which equals the yield strength. That is 17,500 psi in the CV body at 400°F. The maximum calculated normal vertical stress in the neck is 13,582 psi. This value is less than the allowable stress, although it occurs at a stress concentration so the threa9ed joint is clearly acceptable.

Notice that the allowable maximum stress in the closure nut is 3(9900 psi)= 29,700 psi at 400°F. This exceeds the maximum calculated stress intensity in the nut, which is 28,607 psi per Fig. 10 in Attachment B.

NB-3227.2 (WB-3232.2) Pure Shear Pure shear occurs across threads on the CV body and the closure nut. These threads are 7.0-in., 8 threads per inch, push buttress threads Class 2A fit per Ref. 3 (Bl.9), ANSI Bl.9-1973. The threads were not modeled in complete detail and they are evaluated using a traditional method [Ref 2(B 1.1 )]. The allowable stress for the closure nut, two times 9900 psi at 400°F or 19,800 psi, is from the table for bolt materials.

The internal threads are limiting because of the lower allowable stress for the CV body material. The appropriate shear area on internal threads is the cylindrical area at the tip of the external thread with minimum height. That is the area at the minimum major diameter of the external thread called MIN Ds in Ref. 3(B 1.9). MIN Ds is the nominal Ds, D - G, where D is the nominal diameter and G is the allowance for easy assembly minus the tolerance on D. The minimum width of the internal thread at this radius, say

the crest truncation,/ (=0.14532p), and the sum of radial allowance and tolerances (the gap). The gap based on thread tolerances is half the tolerance on the pitch diameter and half the tolerance on the major diameter of the thread. The gap should also include any outward radial deformation of the threads.

Figure 32 shows that due to rotation of the flange, the calculated displacements are smaller than the thread tolerances. So, limited to thread properties PD to!

MIN Ds = 7 in.-0.0067-0.0l0lin. = 6.9832in.

Three threads are fully engaged so the shear area is at least As,; = 3(0.08956in.)1r (6.9832in.) = 5.894in 2

• The shear capacity given the Code limit on shear stress of 0.6 Sm is 0.6 (15,800 psi)(5.894 in.2)

= 55,900 lb.

The load due to pressure to the outer edge of the inner 0-ring groove plus gasket seating is 5961 lb. This is much less than the shear capacity, so the threads are acceptable for shear. By inspection, the external threads are also acceptable.

NB-3232.3 (WB-3232.4) Fatigue Analysis of Bolts The threads are loaded by torque applied to close the CV in addition to the previously considered internal pressure and gasket seating loads. The specified nut torque on assembly Drawing M2E801580A01 l is 120 +/- 5 ft-lb. From Ref. 11 (Laughner & Hargan), the ratio of axial force, P (lb.), to torque, T (in.-lb.) is 1/2 = }(p v + d P m), where D = mean bearing diameter of nut (in.),

dp = pitch diameter of screw thread (in.),

v = coefficient of friction between nut and bearing surface, tan(,B + ¢)

m =----,where cosa a = one-half of thread profile angle (degrees),

The threads are 7-in. nominal diameter with 8 threads per inch or having a pitch of0.125 in. From Ref. 3 (Bl.9) the pitch diameter is dP = 7in.-0.6(0.125in.) = 6.93in.

The thread profile angle at the mating surfaces is 7° so a = 3.5°.

The mean effective bearing diameter of the nut is about 5.8 in, so D = 5.8 in.

The referenced drawing specifies for Note 8: "During installation of container vessel lid assembly, apply a light coat ofKrytox grease to the threads and under the nut." A typical value for coefficient of friction for lubricated threads is 0.11, Ref. 11. In this case

RE: ES3100 Pressure Calculations C1 of C1 The lowest pressure at -40 F is an internal pressure of 11.13 psia, and the maximum containment vessel pressure is 134.53 psia at 242.11 F.

RE: ES3100 Pressure Calculations I'm not sure what it means but the specified torque was found in the previous analysis to be insufficient to maintain metal-to-metal contact with an internal pressure of 101.5 psig. The minimum preload force is exceeded for internal pressures greater than 47.4 psig.

The previous "bolt" calculation was based on specified pressures coincident with the extreme temperatures for NCT. Do you have the pressures associated with -40 F. and 242.11 F.?

ES3100 Pressure Calculations

Richard, Please rerun the code calculations for the ES3100 containment vessel with a design pressure of 200 psig at 400 deg F.

Everything else remains the same. The original documents were DAC-EA-900000-A006 and A007.

Thanks, Monty 1
