STD-R-02-016 O 2.0 ITRUCTURAL EVALUATION 2.1 Structural Design 2.1.1 Discussion The principal structural member of the HN-215H package is the containment vessel described in Section 1.2.1. The above components are identified on the cask certification drawing, drawing No. STD-02-077. A detailed discussion of the structural design and performance of these components will be provided below. 2.1.2 Design Criteria The HN-215H cask has been designed to be a simple, strong paskage that will provide maximum flexibility for usage as well as minimum potential exposure to operating personnel. Its size and shielding capacity will allow a variety of payloads to be safely transported. The shield top and bottom are constructed of two laminated steel plates. Cylindrical side valls have an external skin of.875 inches and an internal skin of.375 inches thick plate. These two plates encase a 1.88 inch thickness of lead. Pertinent dimensions of the HN-215H package are provided on the cask certification drawing. The package has been designed to provide well defined load paths which lend themselves to simple, highly reliable structural analysis methods. No new state-of-the-art approaches O have been used for analytical evaluation. All analytical techniques used throughout the SAR are proven methods that have been used in past submittals. Details of these methods are given where used. Regulatory Guide 7.8, "Load Combinations for the Structural Analysis of Shipping Casks", was used in evaluating the HN-215H package. Materials properties used in the analysis can be found in Section 2.3. 2.2 Weights and Center of Gravity The weight of the HN-215H cask and payload is summarized in Section 1.2.5. The center of gravity for the assembled package is located at the approximate geometric center of gravity. 2.3 Mechanical Properties of Materials The HN-215H package is fabricated of ASTM A516 Gr. 70 steel except as noted below. Material properties of the A516 steel are as follows: 70,000 psi F = g 38,000 psi F = eu l F, 42,000 psi (.6 Fg) = ! (N F,y 22,800 psi (.6 Fgy) d 0024k 2-1 _,--n
STD-R-02-016 The vertical plates of the lifting /tiedown lugs are constructed of ASTM s A514 or A517 steel. Material properties used for these steels are as follows: 110,000 to 135,000 psi F = eu 100,000 psi F = gy F, 66,000 to 81,000 psi (.6 Fg) = F,y 60,000 psi (.6 Ftu) = The lid standoffs are constructed of AISI 1018 or equivalent steel plate. Material properties used are as follows: 69,000 psi F = g 40,000 psi F = ey F, 41,400 psi (.6 Feu) = F,y 24,000 psi (.6 Feu) = Lead shielding will possess those properties referenced in ORNL-NSIC-68, Table 2.6, page 84. O Lid studs are fabricated of ASTM A320 Grade L-7 or equivalent steel. Properties used for analysis are as follows: Bar Properties (Per ASTM A320-78) 125,000 psi F = e 105,000 psi F = gy 2.4 General Standards This section demonstrates that the general standards for the package are met. 2.4.1 Chemical and Galvanic Reactions The shield is constructed from heavy structural steel plates. All exterior surfaces are primed and painted with high quality epoxy paint. There will be no galvanic, chemical or other reaction la air, nitrogen or water atmosphere. 2.4.2 Positive Closure j As described in Section 1.2.1, the positive closure system consists i of a primary lid secured by eight high strength ratchet binders and { a secondary lid affixed with eight 3/4 inch diameter studs. In l addition, each package will be sealed with an approved tamper indicating seal to prevent inadvertent and undetected opening. 0024k 2-2

STD-R-02-016 2.4.3 Lifting Devices ( There are four lifting lugs for the package, three lifting lugs for the lid assembly (primary and secondary lids) and a single lifting lug for the secondary lid. All lifting lugs are evaluated versus the requirements of 10 CFR 71 Section 71.45. 2.4.3.1 Package Lifting Lugs For conservatism, the package is assumed to be lifted by only two of the four identical lifting lugs. The maximum package weight is 58,400 lbs. The lug load is calculated as: P = Wa /N; where W Package Weight = g Load Factor, 3 g's a = Number of lugs N = (58,400) (3)/2 87,600 lbs. P = O ^ P.

Should a lug experience a load in excess of 370,200 lbs., it will begin to shear O out locally through the eye, and will have no adverse V effects upon the package's ability to meet other 1 requirements. 1 2.4.3.2 Primary and Secondary Lid Lifting Lugs The primary and secondary lid lifting lugs are identical in size and shape. The following analysis conservatively considers the maximum lug load in order to assess both primary and secondary lid lugs. The maximum lid weight is 5,450 lbs. Using three lugs the load per lug ist (5.450 lbs) (3 g's)/3 lugs P = t 5,450 lbs/ lug P = t This is greater than the secondary lug load oft 3(1150 lbs) = 3450 lbs. pee % / h f.I + O WT 9 7 1,,,,, 1 0024k 2-6

STD-R-02-016 i Therefore, it can be concluded that the primary and i d secondary lid lifting lugs are more than adequate to l resist a load equal to three times their maximum leads. As for the package lifting lugs, the lid lifting lugs fail by local shaarout through the eye and therefore, have no adverst effect upon the r package's ability to meet other requirements of 10CFR71. Since the lid lifting lugs are not capable of reacting the full package load, they will be covered during transit. f 2.4.4 Tiedowns Four tiedown lugs are provided to resist transportation induced loads. The required load factors are: A = 10g (longitudinal) A = 5g (lateral) y A, = 2g (vertical) The four tiedown lugs are located at 90' intervals around the package sidewall at an elevation above the package base. The tiedown arrangement for the HN-215H cask is shown in Figure 2.4.4-1. Tiedown cables are assumed to be fastened to the trailer O at the same elevation as the base of the cask as shown (i.e., top i of trailer deck). From the geometry given in the sketch, the cable tension due to horizontal accelerations can be determined by summing moments about the opposite bottom corner of the package.

The capabilities are outlined in Appendix 2.10.5. I The Finite Element model consisted of a 45' section of the cask outer shell, cask wall top plate, and one-half the lug. The length of the cask model below the tiedown lug was sufficient to eliminate any end (boundary condition) effects from affecting the final j results. To react to the lug loads, the nodes along the bottom of the inside and outside shells were constrained from displacing i vertically. For symmetry, the nodes along the sectional cuts were i onstrained from displacing circumferential1y and rotating about the X (radial) and Z (tertical) axes. i i I Springs were introduced between the inner and outer shells at locations where the shells displaced radially towards each other (compression only) to account for the presence of the lead. The corresponding spring stiffness was estimated for a column of lead I 0024k 2-13
-. ~... - STD-R-02-016 1 l i I i as k = AE/L. Since the purpose of the springs was to prevent i , O fictitious localized bending stresses, placement of the lead spring j was conservatively chosen as one every four inches. l The model, with exception of the spring elements, was' defined entirely of quadrilateral shall elements. The geometry plots are 4 illustrated in Figures 2.4.4-2 to 2.4.4-5. Figures 2.4.4-2 and -3 j have omitted the side lug plate for clarity. The quadrilaterai shell element has both bending and membrane stress capabilities l j with six degrees of freedom at each nodet translations in the nodal x, y, and a directions and rotations about the nodal x, y, and : axis. Each element, either triangular or quadrilateral in shape, was defined by four nodes that lie in a plane. The j thickness at each node in an element was defined in a real constant l l~ table for each element type. ] The element size was decreased in the area of the lug for greater j accuracy. Furthermore, to enhance to model definition, the node l directly adjacent to each of the lug attachment nodes was linerly l' l constrained to move with that node (e.g., Node 2 was linearly constrained to move with Node 1. Node 14 with Node 13, Nodes 99 and i 12'3 to save with Node _111, etc.) to simulate the presence of the l i two-inch wide lug plates. l A 281,000 lb. load was introduced as a 89,000 lb. outward radial l component combined with a 267,000 lb. downward vertical component I lO ^ at Node 622. This is conservatively higher than the cable tension l l V for the HN-215H cask. The lug hole was omitted to decrease the j complexity of the model as any local effects of the hole would not j directly affect the reaction of the outer shell. 1 i Other than the springs between the inner and outer shells, the l contribution of the lead strength was neglected. Also, for 2 conservatism, the cask wall top plate was defined as being one-half j inch thick. j The maximum combined stress occurred at Element 232, directly below the lug, on the outside of the outer shell. The 20.749 psi combined stress was comprised of a 22,792 psi compreseive longitudinal stress, a 5004 psi compressive circumferential stress, 4 and a 164 psi shear stress as shown on page 2-19a. A description of how to interpret element stress output is provided in Appendix 2.10.5. The second highest stress area in the outer shell occurred i around the end of the horisontal lug. In this area, the element with the highest stresses. Element 88, contained a combined stress of 18,203 psi. J l ] The largest outward radial displacement of the outer shell. 0.0417 ) j inches, occurred at Node 1. The largest inward radial displacement j j on the outer shell. 0.0331 inches, occurred at Node 386. 1 Lo 4 0024k 2-14 1 ) i

Conservatively, the outer shell alone is assumed to support this load as a beam. Accordingly, the stress is: MC S =- g I 1 M = SWL = (5)(1/8) (58,400)(88.25) = 3.221 x 106 in-lb 8 C = D = 83.5 - 41.75 in. 2 wd - d' 4 4 I= 64 64~ - 81.75 ) w (83.50 = = 193,843 in and the corresponding stress is: 6 (3.221 x 10 )(41.75) = 694 psi S =- e f I 193,843 j which results in a Margin of Safety of: MS = Fev 1 = 38,000 - 1 = +53.75 S 694 g Therefore, the package can safely react the "Load Resistance" condition.

The stress can be calculated as follows* F = Pr/t Where: 25 psig P = (83.5 .875)/2 = 41.31 inches r = .875 in. (outside shell only) t = (25)(41.31)/.875 = 1180 psi F = Margin of Safety: M.S. = (Fty/F)-1 = (38,000/1180) - 1 + 31.2 = The analysis is conservative due to the presence of the lead and O', internal shell. The lead assures buckling stability of the shell. Pressure across the end is carried in plate bending by a minimum of two inch thick steel plates top and bottom. Assuming a circular plate, unifornly loaded and with edges simply supported, the stress can be calculated as follows: 2 3W(3M+1) /8 vMt (Per "Formulas for Stress f = and Strain" by Roark) Where: (25) w(83.50)2/4 = 136,900 W = t = 2" 1/.33 = 3 M = f = ( (3)(136,900x10)]/(8x (3)(2)2] r f, = 13,618 psi Margin of Safety: M.S. = 38,000/13,618 - 1 M.S. = +1.79 0024k 2-21 , _..... ~ _
STD-R-02-016 MAR 241988 7 -~s It is therefore safe to conclude that the containment vessel can react a 25 psig external pressure without loss of contents. 2.6 Normal Conditions of Transport The HN-215H cask has been designed and constructed, and the contents are limited (as described in Section 1.2.3 above), such that the performance requirements specified in 10CFR71 will be met when che package is subjected to the normal conditions of transport.specified in Subpart F of 10CFR71. The ability of the HN-215H package to satisfactorily withstand the normal conditions of transport has been assessed as described on the following pages. i 2.6.1 Heat A detailed thermal analysis can be found in Section 3.4 wherein the package was exposed to three combinations of solar heating, internal decay heat and-130*F. ambient air. The steady state analysis conservatively assumed a 24-hour day as maximum solar heat load. The maximum steady state temperature was found to be 192*F. These temperatures will have no detrimental effects on the package. 2.6.2 Cold The HN-215H cask containment components are constructed of A516 - x Grade 70 ferritic steel. This material provides appropriate resistance to brittle fracture failures in accordance with the i recommendations for Category III payloads as setforth in NUREG CR-1815. Specifically, package materials selections comply with criteria established in Section 5.3 of NUREG CR-1815. l l 1 (s_,/ i 4 0024k 2-22

(see Appendix 2.10.3). Thus, the Margin of Safety is: M.S. = 100,000 - 1 = 19.69 4,831 For the secondary lid stids, the load is: O P = w(33.87)* x (14.7) x 1 = 828 lbs s 4 2 8 i 1 The tensile strength of the 3/4-10 UNC, ASTM A320 Grade L-7 studs (minor thread dia. = 0.309) is: P = (105,000)(.309) = 32,450 lbs. A Thus, the margin of safety ist M.S. = 32,450/838 - 1 = 37.72 Stresses induced in the cylinder portion of the cask are conservatively estimated by assuming the pressure differential is totally borne by 3/8 inch thick inner shell.

Assuming a circular plate, uniformly loaded and with edges simply supported, the stress can be calculated as follows: 8 3W(3M+1)/8xMt (Per "Formulas for Stress and Strain" by f = Roark) (7.35) (w) (83.50)*/4 = 40,250 lbs. Where: W = t = 2" 1/.33 = 3 M = f = (3)(40250)(10)/8w (3)(2)8 4,006 psi f = r Margin of Safety: M.S. = 38,000/4006 - 1 = + 8.48 O It can therefore be concluded that the packaging can safely react an atmospheric presstire of 0.5 times standard atmospheric pressure. 4 2.6.4 Vibration j Shock and vibration normally incident to transport are considered to have negligible effects on the package. I 2.6.5 Water Spray Since the package exterior is constructed of steel, this test is not required. 2.6.6 Free Drop The free drop height specified by Subpart F of 10CFR71 for the HN-215H package is 12 inches, since the package is greater than 30,000 lbs. gross weight. Three drop orientations are possibles flat end drop, side drop and corner drop. For the flat end drop, the most critical condition will be settlement of the unbonded lead shield at the end opposite the point of impact. For the side drop, local flattening and i impact onto a lifting lug will be evaluated. For the corner drop, the most critical conditions will be impact on the lid edge and its effect on the closure. 0024k 2-24
STD-R-02-016 2.6.6.1 Flat End Drop The evaluation of flat end impact upon settlement of lead shielding closely follows Shappert's approach for a cylindrical lead shield, outlined in Section 2.7.3 of his Cask Designer's Guide, ORNI.-NSIC-68, February ~1970. The lead settlement distance is given by: RWH AH = 2 2r ) (t,c, +Ro ) tr(R Where: AH = Settlement depth (in.) Drop Height (in.) = 12" H = Outer lead radius (in.) = 40.88 in. R = W Weight of Lead (1bs.) = 16,290 lbs. = r = Inner lead radius (in.) = 39.00 in. j t = Thickness of external steel shell (in.) s =.875 in i o, = Steel dynamic flow stress, 50,000 psi J 1 o = Lead dynamic flow stress, 5,000 psi p3 Therefore the settlement depth, 4H, equals 0.068 l inches. This modest settlement "void" in the lead shield,.068 inches, cannot transmit radiation because of the stepped design of the package ends. The innermost solid steel end plates completely back (shield) lead settlement regions at both ends of the package. Thus, lead settlement due to a flat end drop does not compromise, nor alter, the integrity of radiation shielding in any fashion. O 0024k 2-25
STD-R-02-016 2.6.6.2 Side Drop The effect of a side drop on the cask shielding capabilities is evaluated using the methods outlined in Section 2.7.2 of Shappert's Cask Designer's Guide, j ORNL-NSIC-68. The governing equation (2.13) is ~ ' y (0
- R ('pb

H = Fl (0) = 0-1/2 sin 20 F2 (0) = sin O(2-cos 0) - 0 o, = 50,000 psi o = 5,000 psi pb e = 6.35' t, = outer shell thickness = 0.875 in, t, = end plate thickness = 4.00 in. The flattening of the cask is equal to: d = R(1-cos 9) Therefore: d = 0.256 inches Shielding is reduced by side impact as follows: % Shield Reduction = ( E ' )(100) T 360 s Where: T, = Normal Shield Thickness = 0.875 inches Therefore: % Shield Reduction = 0.33 This insignificant reduction of shielding demonstrates that side impact does not compromise the integrity of the package's shielding in any measurable fashion. 4 0024k 2-26 i .. _ _ ~. _. _ _ -. -. _ _ _ _.. _.., _ _ _. - - - _ ~..
STD-R-02-016 The potential for damage to the cask seal resulting from a side drop onto a tiedown lug is also evaluated. Because the lug is located at the upper end of the i I cask, the impact force will be shared by both upper and lower ends. If we conservatively assume, that the lug carries the entire load, then an estimation of the deceleration load can be calculated. j .- p-1 P ) (O O [ i, h Assuming that the lug plate of 514/517 steel deforms the softer 516 steel cylinder wall, a crush depth can be found using a dynamic flow stress of (o ) 50,000 8 psi: U = Ve, Where: U = Total energy - 58,400 (12) = 700,800 in-lbs. V = Crush volume 0 lug "lug = = (21)(2)6 = 426 Substituting and transposing: 6 = 700,800 .334 in. = 42(50,000) Note that this is less than half of the.88 wall thickness. O 0024k 2-27
STD-R-02-016 f Impact velocity is: O. = /2gh v = /2(386.4)12 96.3 in/sec. = Deceleration in g's is then, 96.3 a' - 35.9 g's = = 2g3 2(386.4)(.334) Note that this is within the range of the values found for the corner drop in Section 2.6.6.3 below. The tiedown lug extends r.o the top of the cylinder wall so the wall is backed by the cylinder top ring as well as the lead shielding below it, thus resisting gross radial deflection of the outside cylinder wall. The circularity of the cylinder in this area is insured by the stepped lid. Thus, the sealing surfaces in this area are expected to remain relatively undeformed assuring the preservaticn of the seal. 2.6.6.3 Corner Drop The impact energy associated with a corner drop will be absorbed by inelastic deformation of the corner. Using the "dynamic flow pressure" concept, total deformation of the corner is estimated and used to compute package deceleration. This deceleration is then used to check the integrity of the lid closure. Both steel and lead components of the cask are distorted upon corner impacts. The assessment of deformation and resultant decelerations is based upon a careful consideration of detail corner geometry for a range of assumed deformations. It is assumed that 4 the steel and plates of the cask undergo plastic flexural deformation and do not crush. This flexural deformation of the ends enforces a crushing of the contiguous lead side walls and the thin cylindrical external steel shell. The predictions of peak rigid body impact decelerations are based upon the crush geometry of the lead side walls and the associated external steel shell. Resultant deformation prediction estimates are based upon two energy balance techniques: o The plastic flow pressure concept O 1 1 0024k 2-28 . _. _. - -, _ _ _.. _. -,. _.... - ~. - - _ - -...
STD-R-02-016 l i - C- \\ o An integration of force - deflection relations based upon crush stress approaches. For the plastic. flow stress approach, properties of steel and lead are based upon recommended deformation basis values used by Shappert in the Cask Designer's Guide, ORNL NSIC-68, Section 2.7.1: o = 5,000 psi pb o, = 50,000 psi For the crush stress approach, steel crush properties are assumed.co be equal to approximately 1.5 times the yield stress, approximately the midpoint between yield and ultimate stress. This. conservative approach is intended to account for both strain rate effects and strair. hardening. This provides a crush stress equivalent for steel of 55,000 psi. For lead, the crush stress equivalent is taken as twice yield, .,r 1380 x 2 = 2760 psi, reference Table 2.6, Shappert, Cask Designer's Guide, ORNL-NSIC-68. Analytics used for this estimate are outlined in Appendix 2.10.2. The results are summarized in Table (" 2.6.6.3-1; detailed computer analysis results for the cask configuration follow the table. The deceleration resulting from impact onto the bottom corner of the cask is conservatively used in evaluating the drop onto the top corner of the cask. The actual deceleration for the top corner drop would be significantly less due to the bending of the lid top plate during impact.

STD-R-02-016 Thus, in this instance, the maximum binder force is (m) 92,800 lbs. w/ The allowable load of the binder is rated at 100,000 lbs. (see Appendix 2.10.3). Thus, the Margin of Safety is: M.S. = 100,000/92,800 - 1 = +0.08 The capabilities stated for the binders are established static allowables. They are manufactured from standard carbon steels and fail in the same manner as a bolt. Numerous studies have been conducted on the behavior of bolts under dynamic or impact loading. ORNL-TM-1312 Volume 12 Structural Analysis of Shipping Casks states that carbon steel bolts "possess better physics properties under conditions of shock ths.n indicated by static tests. Increases in the value of stress by a factor of 1.3 and a greater amount of strain before necking occurs were reported". This is substantiated by reference 5, 8, 9, 10, and 11 of the same document. Therefore, it can be concluded that the binders static allowable capabilities will not be lower under shock or dynamic loading. Thus, it can be concluded that the binders will react the impact load and retain the lid. In the case of a top corner impact directly above a binder lug, some bending of the ocatgonal lid corner may occur. This will decrease the distance between the cask binder attachment lugs and would normally induce a damaging compressive load in the binder. This, in turn, could result 's damage to the cask outer shell due to the moment induced in the binder lug. The binder design precludes this since it will allow a significant amount of axial deflection before it will take a compressive load (see Appendix 2.10.3). The lugs at each end of the binder will possess the following yield capability. j 4 O 1 n 0024k 2-35

At this locatien, the minimum Margin of Safety is: 97,500 M.S. = -1 + 0.05 = 92,800 The ratchet binders load the lid top plate with a series of edge moments. The two inch plate of the casks will be evaluated for these loads. Both local and gross effects on this lid top plate are evaluated. For a maximum ratchet binder load of 92,800 lbs., the associated moment introduced into the top plate of the lid is estimated as: M = (92,800)(.375 + 3.5 - 1.50) = 220,400 in-lb.

M = 1 Thus, local moment yield Margin of Safety of the lid is: M.S. = 464,800 - 1 = + 1.11 220,400 l Gross moment capability is assessed using both the d j exterior and interior lid plates. For a uniform edge moment the expression relating stress to moment in a O circular plate is given by Roark ast ) i 0024k 2-41 j

For the circular lid of 83.50" diameter, the corresponding concentrated moment acting on 1/8th of the edge is: M = (50,660) (83.50) (H) = 1,661,160 in-lb. i 8 8 L Thus, the gross moment yield Margin of Safety of the lid is: M.S. = 1,661,160-1 = +6.54 O ' 220,400 The maximum bending stress in the lid can be approximated by applying a pressure load sgainst the lower lid plate which is made up both the lid weight and the weight of the payload. Total force is then l 1 F = (W11d + w )(A } # p p g = (6600 + 20,000) (32.6) cos (43.9') = 624,833 Distributing this force over the face of the lower ) plate the pressure, p, becomes P = F /A A = 11(38.63)* = 4688 in8 p = 624,833/4688 = 133.3 psi O 0024k 2-42
l STD-R-02-016 l The pressure on the secondary lid is applied to the primary lid as a ring load, W, with diameter equal to the bolt circle. Using a 32" bolt circle and a 29" diameter secondary lid place, the ring load is H W = 133.3 I (29)8 876 lb/in = H(32) or 14,026 lb/ radian A finite element model of the lid was used to calculate the stresses resulting from this loading and to evaluate the ability of the lid to act as a composite plate. (See Appendix 2.10.6). The maximum plate stress intensity calculated for the above loading was 33,830 psi and occurred at the lower surface of the lid at the edge of the access hole. The resulting Margin of Safety is 38,000 -1= +0.12 M.S. = 33,830 If a "loose" payload is assumed, an equivalent pressure load against the inside of the secondary lid can be calculated using the payload density, payload O depth and impact acceleration.

Assume the outer edge of the 1" plate is simply supported (diameter = 35.8"). The maximum moment in the plate is given in Roark (5th Edition), Table 24, Case 9a, as: 0024k 2-43

The preload force can be estimated using Equation 6-16 from Shigley, Mechreical Engineering Design, 3rd Edition: T = 0.20 T d bp Vtere T is the bolt torque (100 ft-lbs.), F, is the bolt preload and d is the bolt diameter (.75 in.) F = 100 ft-lb (12in/ft) = 8,000 lb. P .20(.75 in.) Impact force reacted by the bolt is: T = 95,320 11,915 lbs. = bi 8 J These brees are aco.' because the gasket "spring" is much sof ter than the stud "spring, thus preventing unloading of the gasket when an additional tension is applied to the bolt.

The loaded length is conservatively estimated by considering only the length of the section which would be deformed during the impact.

The damage to the area immediately _ adjacent to the impact crush zone for the bottom corner drop is minimal. The base plata-to-outer shell weld is O partially crushed but thin does not affect the cask integrity. The drain plug is located well outside the crush area and therefore, will not be damaged. The integrity of the cask base can be demonstrated for the bottom corner drop using the base interface forces given in Table 2.6.6.3-3.

I l STD-R-02-016 ANSYS USER'S MANUAL ABSTRACT The AN$y$ computer program is a large-scale general purpose computer program for the. solution of several classes of engineering analysis problems. Analysis capabilities include static and dynamic; elastic, plastic, creep and swelling; buckling; small and large deflections; steady state and tran'slent heat transfeF and fluid flow. The matrix displacement method of analysis based upon finite elpent idealiza-tion is employed throughout the program. The library of finite elements available numbers -ore than forty for static and dynamic analyses, and twenty for heat trans-fer analyses. This variety of elements gives the ANSYS program the capabllity of analyzing two-and three-dimensional frame structures, piping systems, two-dimen-sf onal plane and axisymetric solids, three-dimensional solids, flat plates, axi-symetric and three-dimensional shells and nonlinear problems Including Interfaces and cables. Loading on the structure may be forces, displacements, pressures, temperatures or response spectra. Loadings may be arbitrary time functions for linear and non-linear dynamic analyses. Loadings for heat transfer analyses include Internal heat generation, ccnvection and radiation boundaries, and specified tenparatures or heat flows. The AN$y$ program uses the wave front (or "frontal") direct solution method for the system of simultaneous linear et,tions developed by the metrix displace ont O method, and gives results of high a uracy in a minimum of computer time. The pro-gram has the capability of solving orge structures. There is no limit on the number of ele ents used in a problem. TFsre is no "band width" limitation in the problem de fini tion ; however, there is a "wave f ront" restriction. The '% ave front" restrie-tion depends on the amount of core storage available for a given problem. Up to 576* degrees of freedom on the wave f ront can be handled In a large core. The wave front limitation tends to be restrictive only for analysis of arbitrary three-dimensional structures. AN$y$ has the capebility of generating substructures (or superelements). These substructures may be stored in a library file for use in other analyses. Substruc-turing portions of a redel can result in considerable coguter time savings for non-linear analyses. Gannetry ointtino is avallable for all elements In the ANSYS library, including 1sometric, perspective, section views, and hidden line plots of three-dimensional 4 structures. Plotting routines are also available for the plotting of stresses and displacements f rom two-and three-dimensional solid or shell analyses mode shapes from dynamic analyses, distorted geometries from static analyses, transient forces and displacecents vs. time curves f ree translent dynamic analyses, and stress-strain plots f rom plastic and creep analyses. Postprocessing routines are available for algebrate modification, dif ferentiation, and integration of calculated results. Root-sum-square operations may be performed on selsmic modal resul ts. Response spectra may be generated from dynamit. analysis results. Results f rom various loading modes may be combined for harmonically loaded exisymetric i; O .4tructures. ] An optional 1152 wave f ront is available on some very large computers. 1 A45 TRACT a.) 0024k 2-68
STD-R-02-016 The Input data for the AN5YS program has been designed to'meke It as easy as O possible to define the problem to the coneuter. Options for dultiple coordinate systems in cartesian, cylindelcal, or spherical coordinates are available, as well as multiple region generation capabilities to minimize the input data for repeating regions. Sophisticated geometry generation capabilltles are included for two-dimensional plane and axisyrretric structures and for Intersecting three-dinensional shell and solid structures. The ANSYS program capabilities are continually being enhanced by the addition of new or improved elements, new analysis espabilities, and new Input, output and graphic techniques. The ANSYS USER'S MANUAL is modified periodically to reflect the latest additions. l O ABSTMCT I a.2 0024k 2-69
STD-R-02-016 4,63 1 4.63 QUADRILATERAL $HEl.L This element has both bending and membrane capabilitlet. Both In plane and f normal loads are permitted. The element has six degrees of freedom at sach node: translations in the nodal x, y, and 2 directions and rotations about the nodal x, y, and z ames. Another four-node shell element ($TIF43), restricted to a rectangular or parallelogram shape, has rotated material axes and in plane pressure capabilities i available. 5 The quadrilateral shell has options for verlable thicknesses, elastic foundation supports, suppressing extra shapes, and for concentrating pressure loadings. Stress l stiffening and large rotation capabilities are included. 4.63 1 Inout Data 1 The geometry, nodal point locations, loading,and the coordinate system for this element are shown in Figure 4.631. The element is defined by four nodal points, four thicknesses, an elastic foundation stif fness, and the orthotropic fr.sterial procerties. The material X-olrection corresponds to the element x-direction. The shear modulus term is optional and if it is not included it is coguted from the other input material properties. The thickness 15 assumed to vary smoothly over the area of the element, wi th the thickness input at the four nodal paints. If the element has a constant thickness, only TK(I) need be Input. If the thickness is not constant, all four thicknesses must be input. The elastic foundation stiffness (EF5) is defined as the pressure required to produce a unit normal deflection of the foundation. The elastic foundation cambil-Ity is bypassed if EFS is less than, or equal to, zero. The element loading can be either surface temperatures or pressure, or a co41-nation of both. The positive direction of pressure Is along the positive element z-axis. The pressure loading may be uniformly distributed over the face of the element (KEYSUS(2)=0), or a curved shell loading (KEYSUB(2)=1) consisting of an equivalent element load applied at the nadal points may be used. The latter loading produces { nore accurate stress results in curved shells because certain fictit ' element l bending stresses are elimirated. The KEY $UB(1) option is used to suppress the extra displacement shapes as de-scribed in Section 4.0.6. The KEY $UB(IA) option allows deleting the nominal in-plane rotational s tiffness as described in Section 4.0.7. A sunmary of the shell element parameters is given in Table 4.63 1. A general description of element input, in-cluding the special features, is given in Section 4.0.2. 4.63.2 Outout Data a) Printout - The printout associated rlth the shell elenunt is sumarized in Table 4.63.2. Several items are Illustrated in Figure 4.63 2. A general description of element printout is given in Section 4.0..). Line 2 includes the shear forces NI and NY in the element x and y faces, respectively (posltive in the positive element a direction). The poeents about the a face (MX), the moments about the y face (MY), and the twisting eccent (MXY) are also printed in line 2. The forces and moments are O calculated per unit length in the element coordinate system. The optional edge printout is valid only along free edges of the element. 1 STIF63 0024k 2-70 i
STD-R-02-016 4.63 2 The next three lines include the stresses for top, alddle, and bottom eleeent O. surfaces, respectively. The combined stresses $X and $Y and the twisting stress TIY are the combination of the membrane stresses and the stresses corresponding to the caculated bending coments, respectively. The positive bending stresses occur on the top face of the element for the positive banding moments shown in Figure 4.63 3 Nodal stresses may be obtained from the POST 25 printout, see Section 6.25. b) Post Data - The post data associated with the shell element is sh o..n be i m The O ta arar wri t ten on file TAP!!2, if requested, as described in Section 4.L L.

The bending stif fness Is formed f rom the bending stif f-ness of four triangular shell elements ($TIF53). Two triangles have one diagonal of the element as a com-en side and two triangles have the other diagonal of the element as a comon side. The stiffness is obtained from the sum of the four stiffnesses divided by two. 4.63.4 Assumotions and Restrictions O Zero area ele'wnts are not allowed. This occurs most often whenever the ele-rents are not nuncered properly. Zero thickness elements or elements tapering down to a zero thickness at siy corner are not allowed. The applied transverse thermal credient is assumed to be line~ar through the thickness and uniform over the shall surface. An assemblage of flat shell elements can produce a good approximation to a curved shell surface provided that each flat element does not extend over more than a 15' arc. If an elastic foundation stiffness in Input, one-fourth of the total is applied at each noce. Shear i ef f ection is not included in this thin-shell element. A triangular element may be forced by defIntng duplicate K and L node nurters as described in Section 4.0 9 The extra shapes are automatically deleted for trl-angular elements so that the mer6rane stiffn' ass reduces to a constant strain formu-lation. The four nodal points defining the element should lie in an exact flat planet however, a small out-of-plane tolerance Is permitted so that the element may have a slightly warped shape. A slightly warped element will produce a warning message in the printout. If the warpage Is too severe, a fatal message results and a triangular elvent should be used, see Section 4.0 9. The triangular shape is recommended for large deflection analyses since a four-node element may warp during deflection. The out of-plane (normal) stress for this elenant is assumed to be zero.

STD-R-02-016 O APPENDIX 2.10.6 CASK LID ANALYSIS O O 0024k 2-75
STD-R-02-016 The HN-215H cask lid was analyzed for a pressure load plus a ring load which ,gi simulated the axial impact force imposed on the lid due to its own weight and the weight of the payload. The lid was modelled and analyzed using ANSYS (See Appendix 2.10,5). The lid was considered to be two circular plates connected by two continuous welds as shown in figures 2.10.6-1&2. The remaining interface batveen the plates was represented with gap elements which allowed compressive load transfer but no tensile loads. A coefficient of friction of.5 was used to model the contact friction between plates. A 10 psi pressure was applied to the entire lower surface of the lower plate. A corresponding ring load was applied to the upper surface of the upper plate at a radius of 16" to represent the secondary lid loading. The upper plate was simply supported at its outer edge. The stresses resulting from the analysis are given on the folicwing pages. The maximum stress is found in Element I with a stress intensity of 2450.5 pei. As expected, the stresses decrease with increasing radius. Note also that stresses Elements 8 & 9 and 150 & 151 are relatively low indicating the welds allow the 2" plates to act together as a 4" composite plate. O l O 0024k 2-76

STD-R-02-016 3.0 THERMAL EVALUATION O\\ A thermal analysis for the HN-215H cask has been conducted for normal transport conditions. The performance of the packaging under normal. conditions of transport is described below. 3.1 Discussion The mechanical features of the packaging have been described in Section 1.2.1. There are no special thermal protection sub-systems or features. A very conservative heat load of 400 watts is used to evaluate cask temperatures. However, a much lower heat load is used to calculate the difference in temperature between the payload centerline and the cask surface. These loads (given on page 3-8) are much more realistic because they are based upon the shielding limits of the cask. The external surface of the packaging is predicted to exhibit maximum temperatures ranging from 176'F to 190*F, depending upon the quantity of internal decay heat assumed. The lower temperature predicticn assumes no internal decay heat load of 400 watts. These maximum temperature predictions assume conditions consistent with the Normal Transport "Heat" requirements, specifically: o Direct sunlight (mid-summer) o Ambient Air at 130'F ( o Still air Solar flux is calculated from insolation values given in N.R.C. Regulatory Guide 7.8. The solar flux is assumed constant so that conservative steady state conditions are analyzed. Further conservatism is incorporated in the analysis by assuming the cask base is an adisbatic boundary (no heat loss). The analysis also shows that the internal decay heat (400 watts) raises inside surface temperatures above the external temperatures by less than 0.3*F. Maximum decay heat loads for the HN-215H cask are given below. These are based on a "worst-case" payload of Cesium 137 solidified in concrete. The other payload isotope of interest, Cobalt 60, is shielding limited to much lower Curie levels and thus is not considered here. The total activity is limited by the shielding capability of each cask, assuming a 10mR/hr dose rate at 6 feet from the cask. The values for the KN-215H cask are given in the table on the following page. l 0024k 3-1

The decay heat limit is roughly twice the calculated decay heat to ensure that loading of the casks is governed by shielding considerations and to give added conservatism to the centerline temperatures calculated below. The temperature at the center of the cask can be calculated if we can conservatively assume that the heat flow is entirely radial. The problem can then be treated as a long circular cylinder with uniformly distributed heat sources (Page 53, Krieth, Principles of Heat Transfer, 3rd Ed.) The maximum temperature is given as: i T =T + 4k Where : i T, = outer surface temp. (*/) I radius of outer surface (f t) r = g i k - Thermal conductivity of cylinder material (BTU /hr.ft.*F) The differences between cask centerline temperature and the temperature at the payload outer surface are calculated below using the decay heat limit where: 5'o $3, 4k Cask Decay Heat AT (*F) Limit o Concrete Asphalt Watts BTU /hr (ft) (K=0.8) (K-0.1) i ft* [] HN-215H 9.0 .32 3.22 46 3.68 4 U 0024k 3-2
i STD-R-02-016 /~') The centerline temperature increase is very small for the solidified concrete (_,/ payload. The asphalt temperatures are significantly higher, but these temperatures are based on an activity level which could not be attained in practice because of the lower self shiciding of the asphalt. These results snow that the thermal environment under normal conditions of transport do not have any significant effect on the casks or their payload. 3.2 Summary of Thermal Properties of Materials Only threi of the cask materials were employed in this analysis. They were obtained from conventional handbooks as follows: Thermal Conductivity Steel 25.0 BTU /hr ft *F Lead 18.6 BTU /hr ft *F Concrete 0.8 BTU /hr ft *F Asphalt 0.1 BTU /hr ft *F Surface Emissivity /Absorbitivity f-Steel 0.8 i 3.3 Technical Specification of Components Not applicable - no special thermal sub-systems. 3.4 Thermal Evaluation for Norual Conditions of Transport The thermal analysis for Normal Transport "Heat" and "Cold" conditions is presented in Section 3.6, Appendix. 3.4.1 Thermal Model As outlined in Section 3.6, the unknown external cask temperature was determined by solving for the temperature at which the heat input to the cask system equaled heat output. Input heat consisted of a solar flux (calculated from Reg. Guide 7.8) plus the internal decay heat. Heat output consisted of the sum of free-convection losses and radiation losses to a prescribed ambient air sink temperature (130'F "Hot", -40'F "Cold"). Heat loss was allowed only over the vertical cylindrical sides and the top. Connective film coefficients were taken from McAdams empirical values for free convection. The analysis to determine cask centerline temperature conservatively (T assumes that only radial conduction takes place (i.e., as infinitely \\s_) long cylinder). The decay heat sources are assumed to be distributed evenly throughout the cask interior. 0024k 3-3

i STD-R-02-016 3.4.5 Maximum Thermal Stresses In Section 2.6.3, the critical elements of the cask were evaluated for a pressure differential of 0.5 at (7.35 psi). The internal pressure due to maximum temperature therefore increases stresses predicted in Section 2.6.3 by the factor: 12.45/7.35 = 1.69. The loads and margins of safety thus become: Allmiable j Item Stress Load / Stress Margin 1 Secondary Lid Stud 1399 lbs. 32,450 lb. Large Primary Lid Binders 8165 lbs. 45,000 lb.

There will be no relcase of radioactive material from the containment vessel; 2. The effectiveness of the packaging will not be substancially reduced; 3. There will be no mixture of gases or vspors in the package which could, through any credible increase in pressure or an explosion, significantly reduce the effectiveness of the package. l 3.5 Hypothetical Thermal Accident Evaluation j i Not applicable for Type "A" packages. 3.6 m ndix A Thermal Analysis - Normal Conditions of Transport Hot and cold ambient condition cases are analyzed with the following assumptions: Hot Direct sunlight Ambient Air 6 130*F Internal heat load, 0 & 400 Watts ba 0024k 3-5
