HalfPACT Crediting the Outer Confinement Vessel as the Containment Boundary STRUCTURAL EVALUATION (St)

RAI-St-1 Provide the information listed below to supplement appendix F, report No.

HPT-CAL-0001, Loaded HalfPACT ICV Lifting Evaluation, submitted as part of the application:

a. Include the pertinent information from section 3.1.4 of PDD PT00 in report No. HPT-CAL-0001. Document PDD PT00 is mentioned on the cover sheet of the report but is not referenced.

b. Justify the exclusion of normal conditions of transport (NCT) effects of decay heat, environmental thermal, and internal pressure for the structural evaluation of internal containment vessel (ICV) lid lifting sockets and pins during transfer lift conditions.

c. Provide a description of the anticipated location and ambient conditions during the transfer lift of the ICV from the old outer confinement vessel (OCV) to the new one.

d. Justify the use of Type 304 stainless steel material properties in the transfer lift evaluation, which appears to have been taken from the 70°F entry on table 2.3-1 of the safety analysis report (SAR),

revision 9.

e. Provide a reference for the ICV 506 payload weight and include it in the report.

f. Justify the addition of the simulated ICV payload weight of a 5,485 pounds (lbs.) to the ICV self-weight of 2,215 lbs. to determine the gross allowable lifting capacity of 7,700 lbs.

g. Include the pertinent information from report reference No. 10 in Report No. HPT-CAL-0001 as part of the report content: Washington TRU Solutions 412-L-082, Revision E, Adjustable Center of Gravity Lift Fixture (ACGLF) Leg Weldment & Miscellaneous Details; Lift Leg Weldment.

h. Identify the source of the lifting pin groove locations and widths, as well as pin minimum through-thickness at these locations.

ATTACHMENT A - Responses to RAI The staff notes that the guidance in section 2.4.10 of NUREG-2216 notes that copies of applicable references, if not generally available to the viewer, should be included in the review package. The staff is not familiar with PDD PT00 or the Washington TRU Solutions document 12-L-082.

The latter is needed to verify the method of loading assumed for the lifting pins. In addition, a source for the payload weight of the ICV should be cited in the report to allow verification of a key input parameter for the lifting condition evaluation. The staff notes that revision No. 9 of the table 2.2-1 of the SAR provides the ICV self-weight; cite as a reference.

The ICV is sealed and contains a payload of radioactive material. The staff expects that some decay heat and internal pressure are present at the time of the ICV lift and transfer from the old to the new OCV.

Nevertheless, the application does not include a description of the anticipated location and ambient conditions during the transfer. Therefore, the applicant must justify the omission of decay heat, environmental thermal effects, operating pressure, and use of material properties associated with 70°F in the evaluation of the lid stress during lifting.

An outdoor transfer may present environmental conditions such as increased ambient temperature and insolation. Per section 3.0 of the SAR, revision 9, the maximum ICV decay heat is 30 watts and per section 3.4.4.3, the ICV maximum normal operating pressure is 50 pounds force per square inch gauge (psig). Maximum temperatures for the ICV determined from the thermal analysis of decay heat and insolation conditions are shown in table 3.1-1 of the SAR, rev. 9. [S]ection 2.1.2 of the SAR indicates that container allowable stresses are determined employing the load combination guidance of Regulatory Guide 7.8, Load Combinations for the Structural Analysis of Shipping Casks for Radioactive Material.

In report section 3.2, the allowable OCV lid stress during lifting conditions is determined to be 10,000 psi. The applicant needs to justify the determination of allowable lifting load capacity in report section 4.2.1 as the addition of the self-weight of 2,215 lbs. (resulting in a Von Mises stress of over 2,800 psi, per figure 6) and the payload weight of 5,485 lbs. (resulting in a Von Mises stress of almost 10,000 psi, per figure 7).

Report No. HPT-CAL-0001, section 4.2.2 presents a finite element analysis (FEA) of an individual lifting pin based on its geometry and assumed load application points. From Drawing No. 707-SAR, revision 12, the staff is unable to determine the exact location, width, and depth of the grooves on the lifting pins as stated in this report section and reflected in the FEA. Therefore, the applicant must provide references for this geometrical information. Since the locations of load application to the

ATTACHMENT A - Responses to RAI pin are stated in the report as being based on information for the ICV lift fixture presented in Washington TRU Solutions, 412-L-082, Revision E, the applicant also needs to provide the pertinent portions of this reference in the report.

This information is necessary to demonstrate compliance with the regulatory requirements in 10 CFR Parts 71.43(f), 71.45(a), and 71.51(a).

Response

HPT-CAL-0001 of the application is revised (from Revision 0 to Revision 1) to address items included in the RAI (see Attachment B).

a. PDD PT00 is referenced in the RAI; however SDD PT00 is the applicable document as referenced in HPT-CAL-0001. The pertinent information from Section 3.1.4 of SDD PT00 is that the payload container lift fixtures meet the design requirements of ASME B30.20.

Section 3.2 of HPT-CAL-0001 addresses ASME B30.20. Section 3.1.4 of SDD PT00 is included as Attachment C of this RAI response submittal. For this one-time shipment, the lifting features on ICV 506 may be treated as a payload container lifting device subject to the requirements of SDD PT00 Section 3.1.4.

b. NCT effects of decay heat and environmental temperatures were excluded from the structural evaluation of ICV lid lifting sockets and pins during transfer lift conditions. The use of room-temperature material properties is justified as follows:

i. The loading process will be performed inside the WIPP Waste Handling Building, a temperature and radiologically controlled environment.

ii. The certified payload decay heat plus error (0.02206 watt) is very low per page 2 of WIPP Container Data Report SWD12275, and page 3 of WIPP Payload Data Report SRE033 (see Attachment D).

iii. The ICV lid lifting sockets and pins are Type 304 stainless steel.

Table Y-1 in Section II, Part D, of the ASME Boiler and Pressure Vessel Code specifies the yield strength of SA-240, Type 304, stainless steel plate as 30,000 psi for -20°F to 100°F.

Given the room temperature controlled environment, very low decay heat, and material properties that are constant up to 100°F, the use of 30,000 psi for the stainless steel materials yield strength is justifiable.

HPT-CAL-0001 has been revised to account for internal pressure.

ATTACHMENT A - Responses to RAI

c. The transfer lift of the ICV from the old OCV to the new one will occur in the WIPP Waste Handling Building. The WIPP Waste Handling Building is a steel-frame structure with insulated steel siding. The ventilation systems for the WHB consist of filters, cooling coils, heating elements, fans with associated ductwork, and controls to condition the supply air, maintaining the design temperature between 40°F and 80°F during winter and summer.

d. The ICV lid lifting sockets and pins are Type 304 stainless steel. The ASME Boiler and Pressure Vessel Code evaluation (see response to RAI St-1(b), above) of this material at room temperature is applicable to the transfer lift of the ICV 506 from the old OCV to the new one in the temperature-controlled WIPP Waste Handling Building.

e. The payload weight for ICV 506 is 409.3 kilograms (902.35 pounds),

including uncertainty, per page 2 of WIPP Container Data Report SWD12275 (see Attachment D). HPT-CAL-0001 has been revised to add a reference to WIPP Container Data Report SWD12275 in the determination of Section 4.1.1, ICV and Payload Weights.

f. HPT-CAL-0001 has been revised to replace the simulated ICV payload weight value with the actual measured payload weight. The empty weight of the ICV assembly is 2,250 pounds per Table 2.2-1 of the HalfPACT SAR. The payload weight for ICV 506 is 409.3 kilograms (902.35 pounds), including uncertainty, per page 2 of WIPP Container Data Report SWD12275 (see Attachment D), for a total gross lifting weight of 2,250 + 902.35 = 3,152.35 pounds.

g. HPT-CAL-0001 has been revised to include the drawing, Washington TRU Solutions, 412-L-082, Rev. E, Adjustable Center of Gravity Lift Fixture (ACGLF) Leg Weldment & Miscellaneous Details; Lift Leg Weldment, in Section 6.1.

h. The source of the lifting pin groove locations and widths is Sheet 8 of HalfPACT SAR drawing 707-SAR. As shown in Section AT-AT on Sheet 8 of HalfPACT SAR drawing 707-SAR, the lift pocket lift pin is a 7/8-inch diameter round bar with two, 1/8-inch wide x 0.470/0.460-inch diameter radial reliefs spaced 3.563 inches apart; the radial reliefs are designed to be the overload failure point rather than the containment boundary structure.

OPERATING PROCEDURES OP-7-1 Clarify in the application section 7.4.4.1, step 2; section 7.4.4.2, step 2; section 8.1.3.5, step 3; section 8.1.3.6, step 2; section 8.1.3.7, step 2; and

ATTACHMENT A - Responses to RAI section 8.2.4.3 that, in addition to the assembly requirements as shown in appendix 1.3.1, Packaging General Arrangement Drawings, of the HalfPACT SAR, the O-ring seals must meet the requirements of section 4.1.1.1 of this application.

Specifically, section 4.1.1.1 of the application describes requirements for the innermost main O-ring seal of the OCV and the OCV vent port plug O-ring seal that are in addition to the requirements in appendix 1.3.1 of the HalfPACT SAR. Both O-ring seals must be important-to-safety Category A butyl rubber.

This information is needed to determine compliance with the regulatory requirements in 10 CFR 71.87 and 71.51.

Response

Section 7.4.4.1, step 2; section 7.4.4.2, step 2; section 8.1.3.5, step 3; section 8.1.3.6, step 2; section 8.1.3.7, step 2; and section 8.2.4.3 are implemented by HPT-PRO-0001 and HPT-PRO-0002. HPT-PRO-0001 and HPT-PRO-0002 have been revised to include a general reference to HPT-PRO-0003, Containment for One-Time Shipment Supporting ICV 506, to direct the required use of Category A butyl rubber O-ring seals.

The reference to HPT-PRO-0003 has been added to page 4 of HPT-PRO-0001, and pages 3 and 25 of HPT-PRO-0002 (see Attachments E and F).

1.0 INTRODUCTION

As discussed in Section 2.5.1, Lifting, of the HalfPACT Safety Analysis Report, 1 the three lift pockets in the HalfPACT inner containment vessel (ICV) lid are designed for lifting either the ICV lid or empty ICV assembly (i.e., lid and body with upper and lower aluminum honeycomb spacers installed).

The lift pockets and surrounding structural components are evaluated to determine the maximum allowable gross weight (i.e., ICV weight plus payload weight) while meeting the requirements of 49 CFR §173.410(b) 2 for DOT Type A packages. These requirements are consistent with the lifting requirements specified in 10 CFR §71.45(a). 3 2.0 DESIGN DESCRIPTION As depicted in Figure 1 and Figure 2, and in Section X-X on Sheet 8 of HalfPACT SAR drawing 707-SAR,1 the ICV lid lift pockets are comprised of a 4-inch, Schedule 80, pipe (4.500-inch outside diameter x 3.826-inch inside diameter; 4.163-inch mean diameter), a 1/4-inch thick x 41/2-inch outside diameter bottom plate, and a 3/8-inch thick x 8-inch outside diameter doubler plate. As shown in Section AT-AT on Sheet 8 of HalfPACT SAR drawing 707-SAR, the lift pocket lift pin is a 7/8-inch diameter round bar with two, 1/8-inch wide x 0.470/0.460-inch diameter radial reliefs spaced 3.563 inches apart; the radial reliefs are designed to be the overload failure point rather than the containment boundary structure.

The empty weight of an ICV is 2,250 pounds per Table 2.2-1 of the HalfPACT SAR.

HPT-CAL-0001 I 1 I 6 of 23 3.0 ALLOWABLE STRESSES 3.1 Material Properties The ICV is fabricated entirely of ASTM A240, 4 ASTM A312, 5 ASTM A376, 6 or ASTM A479, 7 Type 304, stainless steel plate, pipe, and bar stock. Room-temperature material properties are correspondingly delineated in Table 1 as taken from Section 2.5 of the HalfPACT SAR.1 Table 1 - Material Properties for Structural Components Elastic Yield Ultimate Poissons Modulus Strength Strength Material Ratio (psi) (psi) (psi)

Type 304 Stainless Steel 0.3 28,300,000 30,000 70,000 The reasons for using room-temperature material properties are threefold:

1. The loading process will be performed inside the WIPP Facilitys Waste Handling Building, a temperature and radiologically controlled environment.

2. The payload decay heat was determined to be 0.02206 watts, including uncertainty, per page 2 of WIPP Container Data Report SWD12275. 8

3. Table Y-1 in Section II, Part D, of the ASME Boiler and Pressure Vessel Code specifies the yield strength of SA-240, Type 304, stainless steel plate as 30,000 psi for -20 °F to 100 °F.

Given the room temperature controlled environment, very low decay heat, and material properties that are constant up to 100 °F, the use of 30,000 psi for the materials yield strength is justifiable.

3.2 Design Criteria The ICV lift pockets are evaluated to the requirements of 49 CFR §173.410(b)2 for DOT Type A packages, and is consistent with the lifting requirements specified in 10 CFR §71.45(a).3 4

HPT-CAL-0001 I 1 I 7 of 23 Section 20-1.2.2 of ASME B30.20 9 requires that structural and mechanical lifting devices be designed in accordance with ASME BTH-1. Per Section 2-3 of ASME BTH-1, 10 Service Class 0, applies for 1 to 20,000 load cycles over the life of a lifting device. Analyzing for fatigue is not required for a Service Class 0 lifting device and not deemed necessary here since ICV 506 will only be lifted once (or twice) to satisfy its safe return for disposition via the one-time shipment that is requested. Therefore, determination of the maximum load capacity of the ICV lifting components shall be based on combined membrane-plus-bending stresses that are limited to one-third of the materials yield strength, i.e., 30,000/3 = 10,000 psi.

Equivalent stress results are determined by combining stresses based on the distortion-energy (von Mises-Hencky) theory and compared to the allowable stress limit of 10,000 psi.

HPT-CAL-0001 I 1 I 8 of 23 4.0 STRUCTURAL EVALUATION 4.1 Loads 4.1.1 ICV and Payload Weights The empty weight of the ICV assembly is 2,250 pounds per Table 2.2-1 of the HalfPACT SAR.1 The material density for the analysis models used an adjusted value resulting in a lift interface reaction force that equals 2,250 pounds.

The payload weight for ICV 506 is 409.3 kilograms (902.35 pounds), including uncertainty, per page 2 of WIPP Container Data Report SWD12275,8 for a total gross lifting weight of 2,250 +

902.35 = 3,152.35 pounds.

To determine the maximum load capacity of the ICV lift pockets, a downward force is applied at the lower edge of the bodys cylindrical shell transition to simulate the payload weight.

4.1.2 Internal Pressure The HalfPACT ICV gauge pressure, pmax (psig), at the end of a maximum sealed duration of 110,480 days, 11 which corresponds to the maximum time that HalfPACT payload SRE033 can be sealed with the flammable gas concentration remaining below the lower flammability limit of 5%

per Section 5.2.3 of CH-TRAMPAC 12 is determined by the following equation:

p max p rg  p hu  p wv  p a where:

The pressure increase due to radiolytic gas generation, prg (psia), is defined by the ratio of the volume of gas generated and heated to the average ICV gas temperature over the sealed duration, Vrg (liters), to the void volume within the ICV, Vicv = 1,496 liters (per Table 3.4-4 of HalfPACT SAR), as follows:

HPT-CAL-0001 I 1 I 12 of 23 4.2 Evaluations Two ANSYS 17 finite element analysis (FEA) models are utilized to determine the maximum load capacity of the ICV lift pockets.

The first FEA model of the ICV lift pocket region evaluates the components in the load path beyond the ICV lift pin, i.e., the lift pocket, lift pocket doubler, and torispherical head structure.

The second FEA model of the ICV lift pin is a highly refined model that includes the two radial grooves that are used to limit stresses by being the shear-failure point in an excessive overload condition. Each FEA model is discussed in more detail below.

4.2.1 ICV Lift Pocket Region Evaluation As shown in Figure 3 and Figure 4, the overall ICV structural model accurately depicts the entire ICV structure without its internal components such as the aluminum honeycomb end spacers and pallet. The ICV structural model is a 1/6 representation of the entire ICV, and uses symmetry boundary conditions along its radial cut edges for continuity.

The entire ICV lid structure, including the lift pocket, is comprised of solid elements. Given the relatively thin shell structures, quadratic elements are used to ensure accurate results for shell bending stresses. The ICV seal flanges and locking ring are also solid elements. The ICV body cylindrical shell and torispherical head are modeled using shell elements.

With one exception, all parts of the model are bonded together. The lift pocket doubler plate is bonded at its edges: the inside edge to the lift pocket to simulate the full penetration weld, and the outside edge to the torispherical head dome to simulate the fillet weld. The interface between the top surface of the doubler plate and bottom surface of the head dome is set to frictionless which allows the surfaces to move relative to each other.

Although the lift pin is included in the model, its only purpose is to provide the load path to the remainder of the model. Each of the ICVs three lift fixture leg weldments 18 have a locking bar that engages the lift pin at a 3.00-inch diameter and provide for a straight vertical lift. Given the locking bars relatively greater strength and rigidity compared to the lift pin, the lift pin may be reasonably evaluated having two concentrated loads spaced 3.00 inches apart.

HPT-CAL-0001 1 14 of 23 Figure 4 - ICV Lift Pocket Detail For this model, the lift pin is restrained in the vertical (Z) direction 1.50 inches inward from the axisymmetric cut plane, and gravity is applied to the model to determine stresses both empty and when loaded to its maximum capacity. Payload weight is simulated by applying a downward vertical force around the periphery of the ICV bodys cylindrical-to-torispherical shell interface.

With reference to Figure 5, the maximum equivalent stress for an empty, unpressurized ICV structure is 2,897 psi, and occurs at the outside surface of the lids torispherical dome at the outside edge of the lift pocket doubler plate.

With reference to Figure 6, the maximum equivalent stress for an empty, pressurized ICV structure is 5,131 psi, and occurs at the inside surface of the lids torispherical knuckle.

With reference to Figure 7, the maximum equivalent stress for a loaded, pressurized ICV structure is 6,045 psi, and once again occurs at the inside surface of the lids torispherical knuckle.

Figure 8 illustrates the reaction force vector in the vertical direction for the final analysis case with a loaded, pressurized ICV (525.4-pound reaction force; multiply by six to get the total reaction load, i.e., 6 x 525.4 = 3,152.4 pounds).

HPT-CAL-0001 1 17 of 23 4.2.2 ICV Lift Pin Evaluation As discussed in Section 4.2.1, ICV Lift Pocket Region Evaluation, the lift pin is subject to bending and shear loads due to the vertical load applied by ICVs lift fixture.18 Thus, the lift pin is evaluated by applying two concentrated loads of 525.4 pounds spaced 3.00 inches apart.

Since the lift pin is fully welded into the lift pocket, the lift pin may be treated as a fixed-fixed cylindrical beam in bending and shear, with the beams length based on the inside diameter of the lift pockets 4-inch, Schedule 80, pipe (4.500-inch outside diameter x 3.826-inch inside diameter).

To perform this evaluation, a high-resolution ANSYS FEA model of the lift pin is used. The lift pins geometry, as shown in Figure 9, includes its two 1/8-inch wide radial grooves with a full 1/16-inch bottom radius per Section AT-AT on Sheet 8 of HalfPACT SAR drawing 707-SAR.1 Figure 10 presents the equivalent stress results by combining stresses based on the distortion-energy (von Mises-Hencky) theory. The resulting maximum stress of 11,971 psi occurs at the surface of the 1/16-inch radius in the grooves. Since the stress distribution through the pins thickness clearly shows these stresses in the grooves to be peak stresses, the center section through the groove was linearized to separate primary membrane-plus-bending stresses from peak stresses, given that the peak stresses are only important from a fatigue failure standpoint. As said earlier, since only one (or two) lifts will be performed, evaluating for fatigue is not required.

As shown in Figure 11, the resulting maximum equivalent stresseq, for membrane-plus-bending is 6,639 psi. *LYHQDQDOORZDEOHVWUHVVa = 10,000 psi, for the Type 304 stainless steel lift pin material, the design margin for each lift pocket lift pin, DMLP, is:

HPT-CAL-0001 I 1 I 19 of 23 4.2.3 ICV Lift Overload Evaluation Since the materials of construction are identical for all of the ICV structural components, and since the design margin for the ICV lift pocket region (+0.65) exceeds the design margin for the lift pin (+0.51), overload failure will occur in the lift pins radial grooves, as intended, before ICV containment integrity is compromised due to failure of any other components in the lift pocket region that comprise the inner containment vessel structure.

5.0

SUMMARY

The minimum lifting design margin for this payload is 51%. Furthermore, per Section 8.1.2.1 of the HalfPACT SAR,1 the bounding design load of the ICV lifting sockets is 5,000 pounds, and load testing to 7,500 pounds is required. Successful load testing and post-test non-destructive testing, coupled with the validation of this evaluation, ensures that the ICV lifting features will operate safely as designed for the loaded ICV 506.

1.0 INTRODUCTION

1.1 Purpose The purpose of this procedure is to support transferring Inner Containment Vessel (ICV) 506, containing Payload SRE033, to a different Outer Confinement Vessel (OCV)/Outer Confinement Assembly (OCA) and preparing the HalfPACT package for a one-time shipment by performing a helium leak test on the OCV.

The OCV shall serve as the containment boundary for this one-time shipment.

1.2 Background

HalfPACT 506 with Payload SRE033 was sent from the Savannah River Site (SRS) on August 25, 2022, and received on August 26, 2022, at the Waste Isolation Pilot Plant (WIPP)

(Shipment SR220010). During the processing of the package, which includes venting and sampling of the ICV headspace prior to ICV lid removal, internal airborne plutonium-238 and americium-241 contamination was detected. WIPP safety protocol prevents opening the potentially contaminated ICV and dictates its return to SRS for investigation into the possible contamination source. The ability to return HalfPACT 506 is currently precluded because its mandatory 5-year maintenance certification expired on September 1, 2022, such that the unit is out of compliance with Certificate of Compliance (CofC) No. 9279.

In order to return ICV 506 with its payload to SRS, the loaded ICV 506 will be transferred from HalfPACT 506 OCA to a different HalfPACT OCA. Use of an alternate HalfPACT OCA is supported through the application of targeted acceptance tests, maintenance activities, and operating procedures to credit the OCAs OCV as the containment boundary for this one-time shipment.

1.3 Format The format of this document will utilize a format similar to Chapter 7.0, Operating Procedures, of the HalfPACT Safety Analysis Report (SAR) including identical section numbering to facilitate ease of review. Sections that may not be applicable due to the situation of this one-time shipment are noted accordingly. Change bars are included for information that is different than the currently approved HalfPACT SAR, Revision 9, but specific to this one-time shipment authorization.

~I~I[gm Mining Contractors HPT-PRO-0001, Rev. 2 April 2023 7.0 OPERATING PROCEDURES 7.1 Procedures for Loading the Package This section delineates the procedures for loading a payload into the HalfPACT packaging, and leakage rate testing the outer confinement vessel (OCV). Hereafter, reference to specific HalfPACT packaging components may be found in Appendix 1.3.1, Packaging General Arrangement Drawings, of the HalfPACT SAR.

The loading operation shall be performed in a dry environment. In the event of precipitation during outdoor loading operations, precautions, such as covering the OCV cavity shall be implemented to prevent water or precipitation from entering the cavity. If precipitation enters the cavity, the free-standing water shall be removed prior to loading the payload.

Based on the current configuration of the HalfPACT packaging when preparing for loading, begin at the section applicable to the following criteria:

x If the HalfPACT package will be loaded while on the transport trailer or railcar, proceed directly to Section 7.1.2, Outer Confinement Assembly (OCA) Lid Removal.

x If the outer confinement assembly (OCA) lid has already been removed, proceed directly to Section 7.1.3, Inner Containment Vessel (ICV) Lid Removal.

x If the OCA lid has already been removed, proceed directly to Section 7.1.4, Loading the Payload into the HalfPACT Package.

7.1.1 Removal of the HalfPACT Package from the Transport Trailer/Railcar

1. Uncover the forklift pockets located at the base of the OCA body.

2. Disengage each of the four (4) tie-down devices on the transport trailer or railcar from the corresponding tie-down lugs on the package.

CAUTION: Failure to disengage the tie-down devices may cause damage to the packaging and/or transport trailer/railcar.

3. Using a forklift of appropriate size, position the forklifts forks inside the forklift pockets.

4. Lift the package from the transport trailer or railcar and move the package to the loading station.

5. Place the package in the loading station and remove the forklift.

7.1.2 Outer Confinement Assembly (OCA) Lid Removal

1. If necessary, clean the surfaces around the joint between the OCA lid and body as required.

2. Remove the OCV seal test port access plug, OCV seal test port thermal plug, and OCV seal test port plug.

3. Remove the OCV vent port access plug, OCV vent port thermal plug, and OCV vent port cover.

4. Remove the OCV vent port plug to vent the OCV cavity to ambient atmospheric pressure.

2

~I~I[gm Mining Contractors HPT-PRO-0001, Rev. 2 April 2023

5. Remove the six 1/2-inch lock bolts (socket head cap screws) from the exterior of the OCA thermal shield.

6. Optionally install a vacuum pump to the OCV vent port and evacuate the OCV cavity sufficiently to allow the OCV locking ring to freely rotate. Rotate the OCV locking ring approximately 10º counterclockwise until the exterior alignment mark indicates the unlocked position. If used, disconnect the vacuum system and equalize pressure to the OCV cavity.

7. Rig an overhead crane, or equivalent, with an appropriate lift fixture capable of handling the OCA lid. Engage the lift fixture and remove the OCA lid from the OCA body. Store the OCA lid in a manner such that potential damage to the OCA lids sealing region is minimized.

7.1.3 Inner Containment Vessel (ICV) Lid Removal Section not applicable. ICV 506 was loaded with Payload SRE033 in compliance with CofC 9279 on August 23, 2022, shipped from SRS on August 25, 2022, and received at WIPP on August 26, 2022. Because potential for airborne contamination was identified during the venting of the unit upon receipt at WIPP, ICV 506 was re-sealed for temporary storage and remains sealed.

7.1.4 Loading the Payload into the HalfPACT Package ICV 506 was loaded with Payload SRE033 in compliance with CofC 9279 on August 23, 2022, and received at WIPP on August 26, 2022. ICV 506 with Payload SRE033 remains sealed. This section describes the procedures for transferring the loaded ICV 506 into an OCV capable of serving as a containment boundary.

HPT-CAL-00011 documents the lifting analysis performed to ensure the as-loaded ICV can be lifted and placed into an alternate OCV. The original fabrication traveler required a load test be performed on the ICV lids with the requirement of 7500 pounds, +1000/-0.

1. Connect an appropriate lifting device to ICV 506.

2. Balance the ICV to ensure it does not damage the OCV sealing region during the loading operation.

3. Lower the ICV into the OCV cavity; disconnect and remove the lifting device.

7.1.5 Inner Containment Vessel (ICV) Lid Installation Section not applicable. ICV 506 was loaded with Payload SRE033 in compliance with CofC 9279 on August 23, 2022, shipped from SRS on August 25, 2022, and received at WIPP on August 26, 2022. Because potential for airborne contamination was identified during the venting of the unit upon receipt at WIPP, ICV 506 was re-sealed for temporary storage and remains sealed.

1.0 INTRODUCTION

1.1 Purpose The purpose of this document is to discuss the acceptance tests and maintenance program required to be implemented on the HalfPACT packaging prior to the one-time shipment supporting ICV 506.

1.2 Background

HalfPACT 506 with Payload SRE033 was sent from the Savannah River Site (SRS) on August 25, 2022, and received on August 26, 2022, at the Waste Isolation Pilot Plant (WIPP)

(Shipment SR220010). During the processing of the package, which includes venting and sampling of the inner containment vessel (ICV) headspace prior to ICV lid removal, internal airborne plutonium-238 and americium-241 contamination was detected. WIPP safety protocol prevents opening the potentially contaminated ICV and dictates its return to SRS for investigation into the possible contamination source. The ability to return HalfPACT 506 is currently precluded because its mandatory 5-year maintenance certification expired on September 1, 2022 such that the unit is out of compliance with Certificate of Compliance (CofC)

No. 9279.

In order to return ICV 506 with its payload to SRS, the loaded ICV 506 will be transferred from HalfPACT 506 OCA to a different HalfPACT OCA. Use of an alternate HalfPACT OCA is supported through the application of targeted acceptance tests, maintenance activities, and operating procedures to credit the OCAs OCV as the containment boundary for this one-time shipment.

1.3 Format The format of this document will utilize a format similar to Chapter 8.0, Acceptance Tests and Maintenance Program, of the HalfPACT Safety Analysis Report (SAR), including section numbers, to facilitate ease of review. Sections that may not be applicable due to the situation of this one-time shipment are noted accordingly. Change bars are included for information that is different than the currently approved HalfPACT SAR, Revision 9, but specific to this one-time shipment authorization.

8.1.4 Component Tests 8.1.4.1 Polyurethane Foam This section establishes the requirements and acceptance criteria for installation, inspection, and testing of rigid, closed-cell, polyurethane foam utilized within the HalfPACT packaging.

8.1.4.1.1 Introduction and General Requirements The polyurethane foam used within the HalfPACT packaging is comprised of a specific formulation of foam constituents that, when properly apportioned, mixed, and reacted, produce a polyurethane foam material with physical characteristics consistent with the requirements given in this section. In practice, the chemical constituents are batched into multiple parts (e.g.,

parts A and B) for later mixing in accordance with a formulation. Therefore, a foam batch is considered to be a specific grouping and apportionment of chemical constituents into separate and controlled vats or bins for each foam formulation part. Portions from each batch part are combined in accordance with the foam formulation requirements to produce the liquid foam material for pouring into a component. Thus, a foam pour is defined as apportioning and mixing the batch parts into a desired quantity for subsequent installation (pouring).

The following sections describe the general requirements for chemical composition, constituent storage, foamed component preparation, foam material installation, and foam pour and test data records.

8.1.4.1.1.1 Polyurethane Foam Chemical Composition The foam supplier shall certify that the chemical composition of the polyurethane foam is as delineated below, with the chemical component weight percents falling within the specified ranges. In addition, the foam supplier shall certify that the finished (cured) polyurethane foam does not contain halogen-type flame retardants or trichloromonofluoromethane (Freon 11).

Carbon ....................... 50% - 70% Phosphorus .................... 0% - 2%

Oxygen ...................... 14% - 34% Silicon ................................. < 1%

Nitrogen ...................... 4% - 12% Chlorine............................... < 1%

Hydrogen..................... 4% - 10% Other ................................... < 1%

8.1.4.1.1.2 Polyurethane Foam Constituent Storage The foam supplier shall certify that the polyurethane foam constituents have been properly stored prior to use, and that the polyurethane foam constituents have been used within their shelf life.

6

HPT-PRO-0002, Rev. 2 Mining Contractors April 2023 8.1.4.1.1.3 Foamed Component Preparation Prior to polyurethane foam installation, the foam supplier shall visually verify to the extent possible (i.e., looking through the foam fill ports) that the ceramic fiber insulation is still attached to the component shell interior surfaces. In addition, due to the internal pressures generated during the foam pouring/curing process, the foam supplier shall visually verify that adequate bracing/shoring of the component shells is provided to maintain the dimensional configuration throughout the foam pouring/curing process.

8.1.4.1.1.4 Polyurethane Foam Installation As illustrated in the accompanying illustration, OCA LID OUTER FOAM FILL PORT the direction of foam rise shall be vertically CENTER FOAM FILL PORT (TYP. 4 PLCS) aligned with the shell component axis.

FOAM RISE The surrounding walls of the component shell DI RECTION where the liquid foam material is to be installed shall be between 55 ºF and 95 ºF prior to foam installation. Measure and record the component shell temperature to an accuracy of +/-2 ºF prior to foam installation.

In the case of multiple pours into a single I I foamed component, the cured level of each pour shall be measured and recorded to an accuracy OCA BODY of +/-1 inch.

Measure and record the weight of liquid foam material installed during each pour to an accuracy of +/-10 pounds.

All test samples shall be poured into disposable containers at the same time as the actual pour it represents, clearly marking the test sample container with the pour date and a unique pour identification number. All test samples shall be cut from a larger block to obtain freshly cut faces. Prior to physical testing, each test sample shall be cleaned of superfluous foam dust.

8.1.4.1.1.5 Polyurethane Foam Pour and Test Data Records A production pour and testing record shall be compiled by the foam supplier during the foam pouring operation and subsequent physical testing. Upon completion of production and testing, the foam supplier shall issue certification referencing the production record data and test data pertaining to each foamed component. At a minimum, relevant pour and test data shall include:

x formulation, batch, and pour numbers, with foam material traceability, and pour date, x foamed component description, part number, and serial number, x instrumentation description, serial number, and calibration due date, 7

HPT-PRO-0002, Rev. 2 Mining Contractors April 2023 x pour and test data (e.g., date, temperature, dimensional, and/or weight measurements, compressive modulus, thermal conductivity, compressive stress, etc., as applicable), and x technician and Quality Assurance/Quality Control (QA/QC) sign-off.

8.1.4.1.2 Physical Characteristics The following subsections define the required physical characteristics of the polyurethane foam material used for the HalfPACT packaging design.

Testing for the various polyurethane foam physical characteristics is based on a formulation, batch, or pour, as appropriate, as defined in Section 8.1.4.1.1, Introduction and General Requirements. The physical characteristics determined for a specific foam formulation are relatively insensitive to small variations in chemical constituents and/or environmental conditions, and therefore include physical testing for compressive modulus, Poissons ratio, thermal expansion coefficient, thermal conductivity, and specific heat. Similarly, the physical characteristics determined for a batch are only slightly sensitive to small changes in formulation and/or environmental conditions during batch mixing, and therefore include physical testing for flame retardancy, intumescence, and leachable chlorides. Finally, the physical characteristics determined for a pour are also only slightly sensitive to small changes in formulation and slightly more sensitive to variations in environmental conditions during pour mixing, and therefore include physical testing for density and compressive stress.

8.1.4.1.2.1 Physical Characteristics Determined for a Foam Formulation Foam material physical characteristics for the following parameters shall be determined once for a particular foam formulation. If multiple components are to be foamed utilizing a specific foam formulation, then additional physical testing, as defined below, need not be performed.

ICV 506 was loaded with Payload Assembly SRE033 in compliance with CofC 9279 on August 23, 2022, and received at WIPP on August 26, 2022. Credit will not be taken for containment provided by the ICV.

8.2.3 Subsystems Maintenance 8.2.3.1 Fasteners All threaded components shall be inspected annually for deformed or stripped threads. Damaged components shall be repaired or replaced prior to further use. The threaded components to be visually inspected include the lock bolts, the OCV and ICV seal test port and vent port plugs, the OCV and ICV vent port covers, and OCV access plugs.

8.2.3.2 Locking Rings Before each use, inspect the OCV and ICV locking ring assemblies for restrained motion. Any motion-impairing components shall be corrected prior to further use.

8.2.3.3 Seal Areas and Grooves 8.2.3.3.1 Seal Area Routine Inspection and Repair Before each use and at the time of seal replacement, the OCV sealing surfaces shall be visually inspected for damage that could impair the sealing capabilities of the HalfPACT packaging.

Damage shall be corrected prior to further use (e.g., using emery cloth restore sealing surfaces) to the surface finish specified in Section 8.2.3.3.2.4, Surface Finish of Sealing Areas.

Upon completion of OCV seal area repairs, verify depth of O-ring groove does not exceed the value in Section 8.2.3.3.2.5, O-ring Groove Depth, when repairs are in the O-ring groove; perform leakage rate test per the applicable section of Section 8.2.2, Maintenance/Periodic Leakage Rate Tests.

8.2.3.3.2 Annual Seal Area Dimensional Inspection In order to demonstrate compliance of the OCV main O-ring seal regions, annual inspection of sealing area dimensions and surface finishes shall be performed as defined in Section 8.2.3.3.2.1, Groove Widths, through Section 8.2.3.3.2.5, O-ring Groove Depth.

Allowable OCV measurements for these dimensions are based on a minimum O-ring compression of 10.73%, which will ensure leaktight seals are maintained (see calculation in Appendix 2.10.2, Elastomer O-ring Seal Performance Tests, of the HalfPACT SAR, for the ICV seal flanges; this calculation is also applicable to the OCV seal flanges since their cross-sectional geometry is intentionally identical).

All OCV measurement results shall be recorded and retained as part of the overall inspection record for the HalfPACT package. OCV measurements not in compliance with the following dimensional requirements require repairs. Upon completion of OCV repairs, perform a maintenance/periodic leakage rate test per the applicable section of Section 8.2.2, Maintenance/Periodic Leakage Rate Tests.

HPT-PRO-0002, Rev. 2 Mining Contractors April 2023 8.2.3.3.2.1 Groove Widths The method of measuring the OCV upper (lid) seal flange groove width is illustrated in Figure 8.2-1. As an option, the lid may be inverted to facilitate the measurement process. The measuring equipment includes a Ø0.560 +/-0.001 inch pin gauge of any convenient length, and a

Ø0.250 +/-0.001 inch ball. With reference to Figure 8.2-1, the pin gauge is aligned parallel with the inner lip of the upper seal flange. Acceptability is based on the following conditions:

x Having contact at location c-c and a gap at location d-d is a NO-GO condition indicating that the upper seal flange groove width is acceptable.

x Having contact or a gap at location c-c and contact at location d-d is a GO condition indicating that the upper seal flange groove width is unacceptable.

The method of measuring the OCV lower (body) seal flange groove width is illustrated in Figure 8.2-2. The measuring equipment includes a Ø0.273 +/-0.001 inch pin gauge of any convenient length, and a Ø0.250 +/-0.001 inch ball. With reference to Figure 8.2-2, the pin gauge is aligned parallel with the outer lip of the lower seal flange. Acceptability is based on the following conditions:

x Having contact at location c-c and a gap at location d-d is a NO-GO condition indicating that the lower seal flange groove width is acceptable.

x Having contact or a gap at location c-c and contact at location d-d is a GO condition indicating that the lower seal flange groove width is unacceptable.

Groove width measurements shall be taken and recorded at six equally spaced locations around the circumference of the seal flanges.

8.2.3.3.2.2 Tab Widths The method of measuring the OCV upper (lid) seal flange tab width is illustrated in Figure 8.2-3.

As an option, the lid may be inverted to facilitate the measurement process. The measuring device is a tab width gauge of any convenient size, with a 0.234 +/-0.001 inch inside width u 0.428 +/-0.001 inch inside height u 0.375 +/-0.005 inch thickness. With reference to Figure 8.2-3, the tab width gauge is aligned parallel with the lowermost lip of the upper seal flange.

Acceptability is based on the following conditions:

x Having contact at location c-c and a gap at location d-d is a NO-GO condition indicating that the upper seal flange tab width is acceptable.

x Having contact or a gap at location c-c and contact at location d-d is a GO condition indicating that the upper seal flange tab width is unacceptable.

The method of measuring the OCV lower (body) seal flange tab width is illustrated in Figure 8.2-4. The measuring device is a 0.494 +/-0.001 inch inside width u 0.250 +/-0.001 inch inside height u 0.375 +/-0.005 inch thick tab width gauge of any convenient size. With reference to Figure 8.2-4, the tab width gauge is aligned parallel with the uppermost lip of the lower seal flange.

Acceptability is based on the following conditions:

x Having contact at location c-c and a gap at location d-d is a NO-GO condition indicating that the lower seal flange tab width is acceptable.

23

HPT-PRO-0002, Rev. 2 Mining Contractors April 2023 x Having contact or a gap at location c-c and contact at location d-d is a GO condition indicating that the lower seal flange tab width is unacceptable.

Tab width measurements shall be taken and recorded at six equally spaced locations around the circumference of the seal flanges.

8.2.3.3.2.3 Axial Play Measurement of axial play shall be performed to ensure that O-ring compression is sufficient to maintain package configuration and performance to design criteria. Axial play is the maximum axial distance that a lid can move relative to a body. Because the seal flange sealing surfaces are tapered, any axial movement where the lid moves away from the body results in a separation of the sealing surfaces and a slight reduction in O-ring compression. The procedure for measuring OCV axial play is as follows:

1. Remove the vent port access plug (OCV only), vent port thermal plug (OCV only), vent port cover, and vent port plug(s).

2. Assemble the lid onto the body.

3. Locate a minimum of six equally spaced locations around the exterior circumference of the lid and body. At each location, place vertically aligned temporary reference marks on the lid and body.

4. Install a vacuum pump to the vent port and evacuate the vessel sufficiently to fully compress the upper seal flange to the lower seal flange.

5. At each location, scribe a horizontal mark that intersects both the lid and the body vertical marks.

6. Install a source of pressure to the vent port and pressurize the vessel sufficiently to fully separate the upper seal flange from the lower seal flange.

7. At each location, scribe a second horizontal mark that intersects either the lid or the body vertical mark (select either the lid or body mark as a base point).

8. Measure and record the difference between the initial and final horizontal marks at each location. The maximum acceptable axial play at any location is 0.153 inch.

9. Other measuring devices, such as dial indicators, digital calipers, etc., may be used in lieu of the reference marking method, provided that the axial play is measured at a minimum of six equally spaced locations.

8.2.3.3.2.4 Surface Finish of Sealing Areas The surface finish in the OCV main O-ring sealing regions shall be a 125 micro-inch finish, or better, to maintain package configuration and performance to design criteria. Perform OCV surface finish inspections for the bottom of the grooves on the lower seal flange and the mating sealing surfaces on the upper seal flange. If the OCV surface condition is determined to exceed 125 micro-inch, repair the surface per the requirements of Section 8.2.3.3.1, Seal Area Routine Inspection and Repair.

24

HPT-PRO-0002, Rev. 2 Mining Contractors April 2023 8.2.3.3.2.5 O-ring Groove Depth Verify the OCV O-ring groove depth to be less than 0.253 inches at six equally spaced locations around the circumference of the seal flanges.

8.2.4 Valves, Rupture Discs, and Gaskets 8.2.4.1 Valves The HalfPACT packaging does not contain any valves.

8.2.4.2 Rupture Discs The HalfPACT packaging does not contain any rupture discs.

8.2.4.3 Gaskets The O-ring seals used during these maintenance activities to support this one-time shipment shall meet the requirements of Section 4.1.1.1, Outer Confinement Assembly (Primary Containment),

of HPT-PRO-0003.2 OCV containment boundary O-ring seals shall be replaced within the 12-month period prior to shipment or when damaged (whichever is sooner), per the size and material requirements delineated on the drawings in Appendix 1.3.1, Packaging General Arrangement Drawings, of the HalfPACT SAR. Following OCV containment O-ring seal replacement and prior to a loaded shipment, the new seals shall be leakage rate tested to the requirements of Section 8.2.2, Maintenance/Periodic Leakage Rate Tests.

8.2.5 Shielding The HalfPACT packaging does not contain any biological shielding. ICV 506 does not contain a shielded container. It was loaded with Payload SRE033, comprised of one standard waste box, in compliance with CofC 9279 on August 23, 2022, and received at WIPP on August 26, 2022.

8.2.6 Thermal No thermal tests are necessary to ensure continued performance of the HalfPACT packaging.
