1 GENERAL INFORMATION

1.1 INTRODUCTION

This safety analysis report (SAR) is for a Type B(U)-96 non-fissile transport package, hereafter identified as a Radioactive Transport Packaging System, AOS Transport Packaging System, or transport package (in general). The transport package is configured in three (3) different sizes, identified as Models AOS-025, AOS-050, and AOS-100. These package models consist of three (3) main components - cask, impact limiter, and cask lid seal - as presented in Section 1.2. The transport packages will be used to transport Type B quantities of encapsulated solid materials or solid metals that meet Normal or Special Form criteria. The authorized quantities of material to be transported is dependent upon the type of material being shipped and the associated decay heat load, or the radioactive shielding requirements, as appropriate, to provide containment and radiation shielding protection of the contents during Normal Conditions of Transport (NCT) and Hypothetical Accident Conditions (HAC) of Transport, as required by Title 10, Code of Federal Regulations, Part 71 (10 CFR 71) [1.1]. The AOS Transport Packaging System components are designed, fabricated, examined, and tested to the applicable requirements of the ASME Boiler and Pressure Vessel (B&PV) Code [1.2] (hereafter referred to as the ASME Code), as summarized in Subsection 2.1.4, Identification of Codes and Standards for Package Design.

Methods and analysis for demonstrating compliance with the requirements of References [1.1] and [1.2]

are present within this SAR. Chapter 2, Structural Evaluation, documents compliance of the design and construction with the requirements of References [1.1] and [1.2]. Compliance is demonstrated by structural analyses and engineering evaluations for Normal and Hypothetical Accident Conditions of Transport requirements, and physical tests upon a prototype packaging, in accordance with 10 CFR 71.71 and 10 CFR 71.73 [1.1]. The mechanical properties for construction materials that affect the structural behavior of the transport packages are also included in Chapter 2.

In addition to the design criteria presented in Chapter 2, allowable stresses are evaluated for possible failure modes, including brittle fracture, fatigue, and buckling. Brittle fracture is not a consideration for the containment vessel, because the structural components are made of 300 series austenitic stainless steel, ASME/ASTM Type 304 or Type 316, including all components of the containment boundary. Austenitic stainless steels are not susceptible to brittle fracture at the minimum design and transport temperature, and their mechanical properties are relatively stable over the range of temperature required by regulations (References [1.1] and [1.4]).

The cask lid attachment bolts are fabricated from ASME SB-637, UNS N07718. This material is also excluded from brittle fracture consideration, in accordance with ASME Code Section III, Division 1, paragraph NB-2311(a)(7) in Reference [1.2].

The structural analyses presented in Chapter 2 fully evaluates the mechanical requirements of the regulations (References [1.1] and [1.4]), and include the applied temperature effects generated by the thermal analyses. The evaluation results verify that the transport packages meet the performance requirements specified by 10 CFR 71 [1.1] and IAEA TS-R-1 [1.4].

Chapter 3, Thermal Evaluation, documents the thermal evaluation required by the regulations, and verifies that the transport packages meet the performance requirements specified by References [1.1]

and [1.4].

Chapter 4, Containment, documents the AOS Transport Packaging Systems containment boundary and capabilities. The chapter also includes the cask lid attachment bolt evaluation.

a. Model AOS-100A is the heaviest of the AOS-100 models and is therefore the bounding case.

b. This method is shown in Equation 6-25, Section 6.12 of Reference [2.28].

Typically in a bolting joint design, a preload torque is assigned to the bolt(s). This is to ensure that the joint will have the capability to react to the applied working load. Therefore, the working load in the bolt must be within the magnitude of, or less than, the resultant load from the preload. In the analysis presented in Table 2-20, the resultant bolt load due to the preload (Fpreload) is 8.00E+03 lbf., while the working load is 330 lbf.a Hence, the preload value of 100 lbf-ft is an adequate value applied to the Model AOS-100 trunnion design. In addition to applying a preload, the bolts are coated with anti-vibration compound prior to installation, to enhance the bolted joints efficiency.

a. The working load value of 330 lbf. is obtained by subtracting the preload force (Fpreload) value of 8.00E+03 lbf.

from the total force (Fb) of 8.33E+03 lbf [2.28].

2.6.5 Vibration Vibration and shock loads are analyzed using the 3D model in three (3) separate analyses. The vibration and shock loads are, conservatively, assumed to be:

Load Case 221 - Forward 10g Vibration Inertia Load

Load Case 222 - Lateral 5g Vibration Inertia Load

Load Case 223 - Vertical 2g Vibration Inertia Load In each analysis, displacements are fixed at the trunnions, and vertical displacement is fixed along the cask and truck bed contact line. The fixed nodes are illustrated in Figure 2-26. The inertia loads are applied as body forces.

The fatigue analysis is presented in Paragraph 4.5.2.6, Cask Lid Attachment Bolt Fatigue Analysis. This analysis considers operating cycles and vibration loads and is based on the ASME Code provided in Reference [2.14].

4.1.4 Closure A set of cask lid attachment bolts, ASME SB-637, UNS N07718, attaches the cask lid to the cask.

The cask lid bolted joint is recessed within the cask body, to protect the joint from transportation loads. The cask lid attachment bolt stress evaluation is presented in Appendix 4.5.2 and follows the methodology and acceptance criteria specified in NUREG/CR-6007 (Reference [4.6]). The cask and bolt features and properties required for the analysis are listed in Table 4-1.

A bolting analysis is performed for Normal and Hypothetical Accident conditions of transport. Ambient conditions of 38°C (100°F) and -40°C (-40°F) are considered. The cask lid and cask lid attachment bolt head are protected in the cask lid design. Cask loadings for pressure, temperature, impact, and vibration are considered in this evaluation. Design conditions for minimum gasket loads and bolt preload are also considered. The Hypothetical Accident conditions of transport ambient temperature of 800°C (1,475°F) is a combination of fire and cool-down transient conditions, following a 30-ft. drop accident event. There are no impact accelerations associated with cool-down, and the evaluation results show that bolting loads are not significant.

Temperatures within the cask lid, cask lid attachment bolts, and cask are used to perform the evaluation, at the locations indicated in Figure 4-6.

Material properties for Model AOS-025A are documented at temperatures of 255°F and 36°F for hot and cold properties, respectively. Basis: The casks seal areas have NCT hot temperatures of 255°F , 286°F, and 293°F for Models AOS-025A, AOS-050A, and AOS-100A, respectively, and cold temperatures of 36°F, 85°F, and 86°F for Models AOS-025A, AOS-050A, and AOS-100A, respectively, as documented in Chapter 3, Thermal Evaluation.

e. Room temperature properties are used for the temperature range of -20°F to 100°F. Because yield and tensile strength properties are inversely proportional with temperature, room temperature properties are conservatively used for lower temperatures. Additionally, the room temperature properties of ASME high strength bolts do not change significantly up to 100°F.

4.5.2 Cask Lid Attachment Bolt Evaluation The following analyses document the bolting evaluation [4.14] of the AOS transport packaging systems cask lid attachment bolts per NUREG/CR-6007 [4.6]. The required thread engagement length is also evaluated.

Note: All references to bolt within this appendix are to the cask lid attachment bolt.

4.5.2.1 Package Accelerations The cask accelerations are required as input for the bolt stress calculations under Hypothetical Accident Conditions (HAC). The cask accelerations are calculated using the total impact load, P, and total cask weight. The weights and impact loads of the packages are documented in Subsection 2.1.3. The total cask weight includes the cask itself, its contents, and the impact limiters, as documented in Table 4-8. The accelerations are calculated by dividing the impact load by the casks overall mass. The Model AOS-025A, AOS-050A, and AOS-100A accelerations are documented in Table 4-9.

a. The full model is used for head-on drop impact load calculations, whereas a half model is used for the side and Cg/Corner drops as documented in Paragraph 2.7.1.5.2.1.1, Paragraph 2.7.1.5.2.1.2, and Paragraph 2.7.1.5.2.1.3 for Models AOS-025A, AOS-050A, and AOS-100A, respectively. Therefore, the weight of the full and half models are used in calculating the accelerations of the Head-on drops, and the Side and Cg/Corner drops, respectively.

b. Acceleration = Impact load / weight.

c. The resultant impact load is calculated using the square root of the sum of the squares of the x and y components.

4.5.2.2 Dynamic Load Factors The equivalent-static acceleration loads for the free drops are equal to the peak rigid body accelerations of the packaging multiplied by a Dynamic Load Factor (DLF) that accounts for possible dynamic amplification within the packaging. The Dynamic Load Factors for the transport packages are determined in the paragraphs that follow.

The DLF is a function of the general shape of the rigid-body acceleration time-history pulse and the ratio of the duration of the rigid body acceleration to the components natural period (t / T). The general shape of the rigid-body acceleration time-history curve is characterized as a half-sine wave. The DLF (or Dynamic Amplification Factor, DAF) for a half-sine wave pulse from NUREG/CR-3966 [4.9], Figure 2.15, is shown in Figure 4-7.

The DAF graph shown in Figure 4-7 is truncated at the ratio of pulse duration (t) to natural period (T) of six (6). However, for ratios greater than one (1), DAF is generally inversely proportional with frequency as shown in Figure 4-7. Therefore, for t / T ratios greater than six (6), the DAF value at ratio of t / T = 6 is conservatively considered.

4.5.2.2.1.2 Impact Duration The impact duration (t) is approximated using the mass, impact initial velocity and impact loads, per methods presented in Reference [4.9], as follows:

t = = 0.0012 sec.

where:

M = 168 lbs./386.4 in/sec2 = 0.43 lb-sec2/in, mass Fmax = 1.97 x 105 lbs., Impact load maximum Vo = = 527 in/sec, initial velocity at impact g = 386.4, in/sec2, gravitational acceleration h = 360 in., drop height (30 ft.)

Accordingly, the ratio of impact duration to the natural period (t / T) = 3.75. Therefore, the corresponding DLF from Figure 4-7 is approximately 1.15.

Accordingly, the ratio of impact duration to the natural period (t / T) = 5.34. Therefore, the corresponding DLF from Figure 4-7 is approximately 1.1. However, a DLF value of 1.15 is conservatively used in the analysis for the Model AOS-050A.

4.5.2.2.3 Model AOS-100A Transport Package Cask Lid Dynamic Load Factor 4.5.2.2.3.1 Natural Frequency The cask lids natural frequency is calculated by considering the cask lid as a simply supported circular plate using Reference [4.10], Table 11.1, Case 2, as follows:

f = = 984.4 Hz, Natural frequency where:

ij = 4.98, dimensionless parameter (for i = j = 0), Reference [4.10], Table 11.1, Case 2 a = 8.295 in., cask lid radius h = 1.49 in., cask lid thickness Eb = 27.0 x 106 psi, modulus of elasticity

4.5.2.2.3.2 Impact Duration The impact duration (t) is approximated using the mass, impact initial velocity and impact loads, per methods presented in Ref. [2]

t = = 0.0063 sec.

where:

M = 9,510 lbs./386.4 in/sec2 = 24.61 lb-sec2/in, mass Fmax = 2.07 x 106 lbs., Impact load maximum Vo = = 527 in/sec, initial velocity at impact g = 386.4, in/sec2, gravitational acceleration h = 360 in., drop height (30 ft.)

Accordingly, the ratio of impact duration to the natural period (t / T) = 6.18. The DAF graph shown in Figure 4-7 is truncated at the ratio of pulse duration to the natural period of 6. However, for ratios greater than 1, DAF is generally inversely proportional with frequency as shown in Figure 4-7. Therefore, for the ratio (t / T) values greater than 6, the DAF value at t / T = 6 is conservatively considered. The corresponding DLF from Figure 4-7 is approximately 1.1. However, a DLF value of 1.15 is conservatively used in the analysis for the Model AOS-100A.

4.5.2.3.2.9 Total Bolt Loads and Stresses To accurately combine total bolt forces, the method of NUREG/CR-6007 [4.6], Table 4.9, is applied. The total tensile bolt force is obtained by adding the total non-prying tensile bolt forces and the total prying tensile bolt forces, as documented in NUREG/CR-6007, Table 4.9, III.I.

The total shear force, as documented in NUREG/CR-6007, Table 4.9, is evaluated as the absolute sum of the shear forces generated by all applied loads.

The combined bending moment is obtained using the combined fixed edge moment and the formula in NUREG/CR-6007, Table 2.2.

As stated in NUREG/CR-6007, Table 4.9, the torsional bolt moment is calculated using the torsional bolt moments from preload.

Bolt stresses are calculated from NUREG/CR-6007, Table 5.1. From the nominal bolt diameter, Db, a new bolt diameter, D, is calculated for stress calculation.

For the tensile stress calculation:

D = Dba where:

Dba = Alternate Bolt Diameter for Stress Calculation = Db - 0.9743p Db = Nominal bolt diameter p = Bolt thread pitch, equals 1 / n n = Number of bolt threads per unit length For the shear stress calculation:

D = Dba (if maximum shear occurs in the thread)

D = Db (if maximum shear occurs in the shank)

For the bending stress calculation:

D = Dba (if maximum bending occurs in the thread)

D = Db (if maximum bending occurs in the shank)

The average bolt direct stress (Sba) that is caused by the tensile bolt force is calculated as follows:

Sba = 1.2732 Fa / D2 The average bolt shear stress (Sbs) that is caused by shear bolt stress is as follows:

Sbs = 1.2732 Fs / D2 The maximum bending stress (Sbb) that is caused by the bending bolt moment is as follows:

Sbb = 10.186 Mbb / D3 4-62 Radioactive Material Transport Packaging System Safety Analysis Report for Model AOS-025, AOS-050, and AOS-100 Transport Packages, Rev. J-3, July 19, 2023 (Docket No. 71-9316)

Sbt = 5.093 Mt / D3 Where Fa, Fs, Mbb, and Mt all represent total values of the tensile bolt force, shear bolt force, bending bolt moment, and torsional bolt moment, respectively.

The resulting stress intensity (Sbi) that is caused by tension + shear + bending + torsion is as follows:

4.5.2.4 Cask Lid Attachment Bolt Thread Engagement Length 4.5.2.4.1 Model AOS-025A Cask Lid Attachment Bolt Thread Engagement Length The required threaded engagement necessary for the threaded joint to carry the applied loads without the threads stripping is calculated using the methods presented in Machinerys Handbook 26 ([4.11],

Page 1490). The Model AOS-025A cask lid attachment bolts are eight, 3/8 - 16 UNC, SB-637 bolts.

For materials of the same strength, the length of engagement to prevent stripping of external threads (Le) is as follows:

Le = = 0.250 in.

where:

Esmin = 0.3287, Minimum pitch diameter of external threads, class 2A ([4.11], Page 1718)

Dsmin = 0.3643, Minimum major diameter of external threads, class 2A ([4.11], Page 1718)

Enmax = 0.3387, Maximum pitch diameter of internal threads, class 3B ([4.11], Page 1718)

Knmax = 0.3182, Maximum minor diameter of internal threads, class 3B ([4.11], Page 1718) n = 16, Number of threads per inch For steels over 100,000 psi ultimate tensile strength, the screw thread tensile stress area is calculated as follows:

At = = 0.0747 in2 Radioactive Material Transport Packaging System Safety Analysis Report 4-91 for Model AOS-025, AOS-050, and AOS-100 Transport Packages, Rev. J-3, July 19, 2023 (Docket No. 71-9316)

The length engagement (Le) applies if the external and internal threads are made of materials of the same strength. If the materials of the internal and external threads do not have the same strength, the relative strength (J) is calculated to determine if the internal thread could strip before the bolt breaks.

The relative strength is calculated as follows:

J = = 1.385 where:

As =

= 0.149 in2, shear area of external threads An = [

2

= 0.211 in , shear area of internal threads Sut = 176.0 ksi, tensile strength of external threads Sut2 = 90.0 ksi, tensile strength of internal threads (insert material)

Because the relative strength (J) is calculated to be greater than 1, the required length of engagement (QL) to prevent stripping of threads is calculated by multiplying the J factor times the calculated length of engagement (Le):

QL = JLe = 1.369 x 0.250 in. = 0.35 in.

The actual length of engagement is calculated by subtracting the length of the cask lid attachment bolt that is embedded in the cask lid from the total bolt length (Lb = 0.63 in. - 0.15 in. = 0.48 in.). The actual length of engagement (Lb) is greater than the required length of engagement QL. Therefore, the engagement length is adequate.

4.5.2.4.2 Model AOS-050A Cask Lid Attachment Bolt Thread Engagement Length The required threaded engagement necessary for the threaded joint to carry the applied loads without the threads stripping is calculated using the methods presented in Machinerys Handbook 26 ([4.11],

For materials of the same strength, the length of engagement to prevent stripping of external threads (Le) is as follows:

Le = = 0.333 in.

where:

Dsmin = 0.4876, Minimum major diameter of external threads, class 2A ([4.11], Page 1719)

Enmax = 0.4548, Maximum pitch diameter of internal threads, class 3B ([4.11], Page 1719)

Knmax = 0.4284, Maximum minor diameter of internal threads, class 3B ([4.11], Page 1719) n = 13, Number of threads per inch For steels over 100,000 psi ultimate tensile strength, the screw thread tensile stress area is calculated as follows:

The length engagement (Le) applies if the external and internal threads are made of materials of the same strength. If the materials of the internal and external threads do not have the same strength, the relative strength (J) is calculated to determine the adequate length of engagement to prevent stripping of threads before the bolt breaks. The relative strength is calculated as follows:

J = = 1.396 where:

As =

= 0.275 in2, shear area of external threads An = [

2

= 0.381 in , shear area of internal threads Sut = 174.0 ksi, tensile strength of external threads Sut2 = 90.0 ksi, tensile strength of internal threads (insert material)

Because the relative strength (J) is calculated to be greater than 1, the required length of engagement (QL) to prevent stripping of threads is calculated by multiplying the J factor times the calculated length of engagement (Le):

QL = JLe = 1.396 x 0.333 in. = 0.47 in.

The actual length of engagement is calculated by subtracting the length of the bolt embedded in the lid from the total bolt length (Lb = 1.0 in. - 0.41 in. = 0.59 in.). The actual length of engagement (Lb) is greater than the required length of engagement QL. Therefore, the engagement length is adequate.

4.5.2.4.3 Model AOS-100A Cask Lid Attachment Bolt Thread Engagement Length The required threaded engagement necessary for the threaded joint to carry the applied loads without the threads stripping is calculated using the methods presented in Machinerys Handbook 26 ([4.11],

Page 1490). The Model AOS-100A cask lid attachment bolts are fourteen, 7/8 - 9 UNC, SB-637 bolts.

For materials of the same strength, the length of engagement to prevent stripping of external threads (Le) is as follows:

Le = = 0.587 in.

where:

Esmin = 0.7946, Minimum pitch diameter of external threads, class 2A ([4.11], Page 1723)

Dsmin = 0.8592, Minimum major diameter of external threads, class 2A ([4.11], Page 1723)

The length engagement (Le) applies if the external and internal threads are made of materials of the same strength. If the materials of the internal and external threads do not have the same strength, the relative strength (J) is calculated to determine if the internal thread could strip before the bolt breaks. The relative strength is calculated as follows:

J = = 1.448 where:

As =

= 0.904 in2, shear area of external threads An = [

2

= 1.207 in , shear area of internal threads Sut = 174.0 ksi, tensile strength of external threads Sut2 = 90.0 ksi, tensile strength of internal threads (insert material)

Because the relative strength (J) is calculated to be greater than 1, the required length of engagement (QL) to prevent stripping of threads is calculated by multiplying the J factor times the calculated length of engagement (Le):

QL = JLe = 1.448 x 0.587 in. = 0.85 in.

The actual length of engagement is calculated by subtracting the length of the bolt embedded in the lid from the total bolt length (Lb = 2.25 in. - 1.04 in. = 1.21 in.). The actual length of engagement (Lb) is greater than the required length of engagement QL. Therefore, the engagement length is adequate.

4.5.2.5 Cask Lid Flange Separation Analysis 4.5.2.5.1 Model AOS-025A Cask Lid Flange Separation Analysis The flange separation is evaluated based on the bolt elongation due to the clamp load of the cask lid attachment bolt. The clamp load is evaluated as the difference between the absolute sum of the applied loads (other than preload and temperature load) and prying load, and the absolute sum of the preload and temperature loads. The flange separation is greatest for the lowest preload torque allowable; therefore, a preload torque of 29 ft-lb is used in the calculations that follow.

4.5.2.6 Cask Lid Attachment Bolt Fatigue Analysis Fatigue analysis is completed for NCT, using a minimum fatigue reduction factor of 4 and ASME fatigue curves I-9.4 [4.13] with elastic modulus adjustment per NUREG/CR-6007 [4.6], Table 6.2. The maximum cumulative usage factor due to alternating stress intensity should be less than 1.

4.5.2.6.1 Model AOS-025A Cask Lid Attachment Bolt Fatigue Analysis The fatigue analysis identifies two stress cycles - Normal operation and vibration cycles. Normal operation loads include preload, temperature, and pressure. The vibration loads are documented based on the applied axial and transverse vibration acceleration loads.

4.5.2.6.1.1 Normal Operation Cycles Fatigue due to operating loads is documented based on the maximum NCT cases. The direct stress is obtained by combining the axial and bending stresses. The shear stress is obtained by combining the average shear load and torsional bolt moment. The maximum principal stress (S1) is calculated from the combined direct and shear stress. Summary of normal operation cycles is documented in Table 4-31.

S1 = = 40,785.2 psi where:

= Sba + Sbb = 11,046 psi (direct stress, Table 4-12)

= Sbs + Sbt = 34,827 psi (shear stress, Table 4-12)

The corresponding alternating stresses (Sa) are calculated using a fatigue reduction factor (RF) of 4 [4.12].

Also, because the fatigue curve ([4.13], ASME Section III, Figure I-9.4) is based on a modulus of elasticity of 30 x 103 ksi, which is different than the modulus of elasticity of the bolt materials, a ratio of the modulus of elasticities is considered in calculating the alternating stress per [4.12], NB-3232.3.

Sa = = 87,396.9 psi where:

RF = 4, Fatigue strength reduction factor [4.12]

Edc = 30 x 103 ksi, Modulus of elasticity on design fatigue curve [4.13]

Ea = 28.0 x 103 ksi, Modulus of elasticity of the bolt materials Radioactive Material Transport Packaging System Safety Analysis Report 4-103 for Model AOS-025, AOS-050, and AOS-100 Transport Packages, Rev. J-3, July 19, 2023 (Docket No. 71-9316)

Using the alternating stress calculated and the fatigue curve for a maximum nominal stress 2.7 Sm in

[4.13], ASME Section III, Figure I-9.4, the corresponding fatigue limits are calculated by interpolating the tabular data provided in [4.13], ASME Section III, Table I-9.0. The estimated fatigue limit, N1, for the 87.4 ksi alternating stress is 1,313 cycles. Based on a weekly transport for five (5) years, the number of normal operation cycles, n1, is 52 cycles/year x 5 years = 260 cycles. The corresponding usage factor (U1) for normal operating cycles is as follows:

U1 = = 0.20 where:

n1 = 260 cycles, operating cycles N1 = 1,313 cycles, allowable cycles 4.5.2.6.1.2 Vibration Cycles Fatigue due to vibration loads are documented based on the applied axial and transverse vibration acceleration loads.

The corresponding alternating stresses (Sa) are calculated using a fatigue reduction factor (RF) of 4 [4.12].

Also, because the fatigue curve ([4.13], ASME Section III, Figure I-9.4) is based on a modulus of elasticity of 30 x 103 ksi, which is different than the modulus of elasticity of the bolt materials, a ratio of the modulus of elasticities is considered in calculating the alternating stress per [4.12], NB-3232.3.

7.1 PACKAGE LOADING Note: The operational steps provided in this section apply to all AOS Radioactive Material Transport Packaging System models (Models AOS-025A, AOS-050A, AOS-100A, AOS-100B, and AOS-100A-S).

Any step specific to a given Model is identified within the step.

Part of the transport package loading preparation is to perform a Pre-Shipment Engineering Evaluation following IAEA TS-R-1, Paragraph 502, 10 CFR 71.87, and 49 CFR 173.475 (References [7.1], [7.2], and

[7.3], respectively). The evaluation is used to ensure that the packaging, with its proposed contents, satisfies the applicable requirements of the transport packages license or certificate. This evaluation includes, but is not limited to, the review of the following:

Proposed contents isotopic composition, quantities, and decay heat;

Proposed contents form, weight, and geometry. If the content is defined as Special form, verify its certification from the competent authorities;

Identify shoring device to be used. All structural shoring materials used within the cask cavity must have a melting point greater than (i) 600°F for Co-60 in metallic form and Cs-137 in the form of cesium chloride and (ii) 900°F for all other contents;

Shielding requirements (use of additional shielding devices may be required for shipment);

Structural requirements;

Thermal requirements;

Pressure requirements;

Shipping hardware (such as liners, racks, dividers, baskets, and shoring devices);

Maintenance records.

Personnel qualification.

Certification Drawing requirements.

In addition, operations at the loading facility must safely support a range of activities, from receiving and inspecting the package, to preparing the loaded transport package for shipment. Each loading facility must provide fully trained personnel and detailed operating procedures to cover these activities.

7.1.1 Preparation for Loading 7.1.1.1 Receiving and Inspecting the Empty Transport Package To receive and inspect the empty transport package:

a. Position the transport vehicle in the Receiving Inspection area.

b. Visually inspect the transport package for damage and proper labeling and marking.

Refer to the shipping paper for shipment category and compare the marking and labels on the package to the requirement of Reference [7.3].

a. Refer to Table 1-5, AOS Transport Packaging System Certification Drawing List - All Models, for drawing revision levels.

b. If the Model AOS-050A axial shielding plates include threaded screw holes, each hole must be filled with a setscrew during shipment.

7.1.2.3 Installing the Cask Lid Note: Visually inspect the cask and lid sealing surfaces, as well as the cask lid seal to be used, for damage that can prevent proper sealing of the sealing joint. Refer to Subsection 8.2.2, Leakage Tests

[8.4], for detailed inspection of these items. If the metallic cask lid seal is replaced, prior to the shipment of Normal Form material, a Maintenance Test must be performed, in accordance with ANSI N14.5 (Reference [7.8]). The elastomeric seal option is acceptable for use only with Special Form contents, in which the cask contents provide containment for the radioactive contents.

To install the cask lid, after verifying that the cask lid seal is properly installed, use proper rigging to slowly lower the cask lid onto the cask. Carefully monitor this operation to ensure that the cask lid is properly aligned. During the placement of the cask lid, two lid guide pins may be installed in the cask lid threaded holes perpendicular to each other to maintain alignment of the cask lid attachment bolt holes with the cask lid threaded holes.

The cask lid attachment bolts must be lubricated with a lubricant such as Neolube No. 2 (note that the lubricant must be approved by AOS).

7.1.3 Preparation for Transport 7.1.3.1 Securing the Cask Lid To secure the cask lid, in preparation for transport:

Note: Torque sequence is stamped on top surface of the cask lid, about the bolt location.

a. Lubricate the cask lid attachment bolts with a lubricant such as Neolube No. 2. The lubricant must be approved by AOS. In the case of wet loading, the lubricant must be applied after the cask has been removed from the pool and dried.

b. Torque the cask lid attachment bolts (refer to Table 7-2), using one of the two conditions listed below.

1. If the cask was dry loaded - Torque the cask lid attachment bolts in a crisscross pattern, with a final pass all the way around, to ensure even seal compression after the elastomeric seal has been visually inspected and installed, -or- a new metallic seal has been installed.

2. If the cask was wet loaded - To torque the cask lid attachment bolts:

a. Install the cask lid and a minimum of at least five (5) bolts in the cask lid, as the cask breaks the waters surface. Note that this step may be skipped with the approval of Radiation Protection.

b. Drain the cask over the pool area. After the water has drained from the cask, move the cask to the decontamination pad.

c. Remove the bolts (previously installed for the transfer) and cask lid.

d. Dry the cask lid attachment bolts and then lubricate with a lubricant such as Neolube No. 2.

e. Dry the sealing surfaces and the bolt threaded holes.

f. Install the cask lid elastomeric seal after it has been visually inspected, -or- a new cask lid metallic seal onto the cask lid, then re-install the bolts and torque the cask lid attachment bolts in a crisscross pattern, with a final pass all the way around, to ensure even seal compression.

Note: For shipments of Special Form material, a Maintenance Leak test is not necessary after replacing a cask lid elastomeric seal, provided that a Periodic Leak test has been performed on the casks containment system within the past 12 months.

8.1.1 Visual Inspections and Measurements Visual examinations of all component surfaces, including welds and dimensional inspections, are conducted during packaging fabrication. These inspections, as well any other NDE inspections, are conducted according to approved written procedures. Their objectives are to identify harmful discontinuities or indications (such as overlaps, seams, cracks, porosity, crevices, and excessive oxidation), and to verify that the component or item critical dimensions are met, as specified in the certification drawings. (Refer to Table 1-5, AOS Transport Packaging System Certification Drawing List -

All Models, for a complete list.)

Visual and dimensional inspection results are recorded in accordance with the Purchasers approved Quality Assurance and Fabrication plan. Refer to Subsection 2.3.2, Examination, for additional details.

8.1.2 Weld Examinations All welds within the cask component and impact limiters are visually inspected and liquid-penetrant tested (root and final passes). Also, the weld within the containment boundary must be ultrasonically examined and liquid-penetrant tested. These inspections are conducted to ensure that no cracks, incomplete fusion, nor lack of penetration exist. Parts that do not meet the established criteria are repaired or replaced, in accordance with written procedures issued by the Fabricator and approved by AOS.

The Model AOS-025, AOS-050, and AOS-100 transport packages use an ASME Code corner type C weld.

This weld configuration is presented in Figure 4-2, Typical Corner Cask Cavity Shell Weld Joint Configuration - All Models.

8.1.3 Structural and Pressure Tests In addition to the test described in Subsection 8.1.2, the cask cavity is hydrostatically tested, to verify that the containment boundary can support the Design Pressure, per the requirements of NB6200, Subsection NB,Section III, of the ASME Code [8.2]. The Test Pressure is 1.5 times (1.5x) the Design Pressure. If this test were to fail, each component of the containment boundary must be evaluated and replaced, if necessary.
