1 Introduction 1.1 Purpose of the Project The Management of the Cesium and Strontium Capsule (MCSC) Project is being executed in accordance with the requirements of DOE O 413.3B, Program and Project Management for the Acquisition of Capital Assets. DOE O 413.3B provides the programmatic and project direction needed to successfully deliver projects within their original performance baseline, cost and schedule, and the capability to meet mission performance and safety goals and considerations. This Technology Maturation Plan (TMP) was prepared in accordance with the requirements of DOE O 413.3B.

The Waste Encapsulation and Storage Facility (WESF) is located in the 200 East Area of the U. S. Department of Energy (DOE) Hanford Site north of Richland, Washington. WESF stores 1,312 cesium capsules, 23 Type-W capsules (overpacked cesium capsules), and 601 strontium capsules underwater in pool cells. The capsules are currently managed as mixed, high-level waste and are regulated under the Resource Conservation and Recovery Act of 1976.

The MCSC Project will provide the capability for retrieval of the cesium and strontium capsules from WESF pool cell storage and placement into a Cask Storage System (CSS) as an interim storage configuration pending final disposition.

The CSS is expected to consist of the following major components: Transportable Storage Canister Basket, Transportable Storage Canister (TSC), and Vertical Concrete Cask (VCC). In addition, Universal Capsule Sleeves (UCS) will be fabricated to hold the capsules and various pieces of equipment and tools will be procured to perform capsule loading and transfer activities. These components and equipment are typical of standard Dry Cask Storage System (DCSS) technology and are routinely employed in the Nuclear Power Plant (NPP) industry at Independent Spent Fuel Storage Installations for Spent Nuclear Fuel (SNF) interim storage.

The MCSC Project scope includes the following three major activities to prepare for transfer and placement of the cesium and strontium capsules, currently stored at WESF, into an interim storage configuration:

1. Acquire storage and transfer systems, and associated equipment necessary to support retrieval, loading, and transfer of the capsules to extended storage – (CSS scope)

2. Perform WESF modifications necessary to support retrieval, loading, and transfer of capsules to the Capsule Storage Area (CSA) from WESF – (WESF Modifications scope)

3. Construct the CSA, including storage pad, fencing, lighting, and road access to the CSA – (CSA Construction scope)

Demonstration of MCSC Project readiness will be followed by capsule transfer operations, including retrieval from existing storage, loading, transfer to the CSA, and emplacement into a dry-storage configuration for an extended period of time (300 years).

Figure 1 shows the major operations (and components) to be performed to load the CSS once the capsules are retrieved from their current storage configuration:

1.2 Purpose of the TMP This TMP outlines the activities to be performed in response to recommended actions identified in the [Ref. 1] DOE Technology Readiness Assessment (DOE-TRA) report. It provides the strategy to mature Critical Technology Elements (CTE) to a Technology Readiness Level (TRL) 6. It also outlines the activities to be performed in response to recommendations from the MCSC Technology Readiness Self-Assessment (MCSC-TRSA) [Ref. 2].

The TMP is a living document and will be periodically reviewed and revised when required to ensure that development and maturation activities successfully lead to a TRL 6 status.

2 Technology Assessments of the Project DOE O 413.3B [Ref. 3] states that TRAs are used as a management tool to reduce the technical and cost risks associated with the introduction of new technologies. The TRA is an assessment of how far project technology development has proceeded (maturity) and its readiness for insertion into the project design and execution schedule. The DOE-Environmental Management (EM) TRA/TMP Guide [Ref. 4] recommends that projects conduct a self-assessment of technology readiness (TRSA) prior to an independent TRA to help inform the project on technology status and to assist DOE with the independent TRA.

2.1 Summary of Previous Technology Readiness Assessment(s) In support of Critical Decision (CD) -1, both the MCSC-TRSA and the DOE-TRA activities were performed during CY 2017. The MCSC-TRSA was performed by MCSC Project Engineering personnel and the DOE-TRA by a team consisting of subject and technical matter experts from within the complex, to include the Office of the Chief Engineer in the DOE-EM. Recommended actions from both assessments centered primarily on activities at the capsule loading stage. Additional recommendations from the DOE-TRA addressed concerns with maturity of the thermal and heat transfer design.

1. Loading of capsules into the UCS

2. Transfer of the loaded UCS to the TSC

3. Inserting the loaded UCS into an already assembled TSC Basket/TSC/VCC staged in the Truck Port.

4. Transfer of the loaded CSS to the CSA pad (CSA).

CHPRC-03403, Rev. 0

Maturity gaps identified in project technology, and system design and analysis, are addressed in this TMP. Details of both the MCSC-TRSA and DOE-TRA can be found in the [Ref. 2 and 1] reports, respectively. The following summarizes the two assessments:

2.1.1. MCSC-TRSA Reference 5 provides a detailed description of the overall process that will be used for transfer of the capsules and placement into dry storage. Based on this description, major project activities and functions were determined from which nineteen individual Technology Elements (TE) were identified; a brief description of each is provided in Attachment A. Three of the nineteen TEs were determined to be CTEs as follows:

1. CTE No. 2A_2B: UCS and Equipment for Welding, Drying, Inspection and Testing (TEs 2A and 2B were combined for CTE evaluation)

2. CTE No. 2C: Capsule Cooling Equipment

3. CTE No. 5A: Temperature Modeling and Capsule Temperature Monitoring

The TRSA-CTEs were evaluated against both TRL 4 and TRL 6 calculator criteria and found to satisfy the requirements with exception of CTE No. 2A_2B. This CTE failed to meet Criterion 12 (from the TRL 4 Calculator [Ref. 4]): Technology demonstrates basic functionality in simulated environment. It was concluded that this CTE has not been sufficiently demonstrated in the relevant environment and was therefore assessed a TRL 4 (-) level.

The [Ref. 2] report concluded that a TMP is needed to mature CTE No. 2A_2B to a TRL 6 level prior to final design.

2.1.2. DOE-TRA The DOE-TRA Team reviewed the MCSC-TRSA approach to organizing the project activities / functions and identification of TEs but took a different approach by grouping the nineteen TEs into four functional systems as shown in Attachment B. These functional systems were evaluated against the [Ref. 4] CTE calculator criteria and three of the four systems (TE #1, #2 and #4) were identified as CTEs:

1. CTE #1: Capsule Loading System

2. CTE #2: UCS Insertion into TSC and Cask

3. CTE #4: Extended Storage at CSA

The DOE-CTEs were evaluated against the [Ref. 4] TRL 3 and 4 calculator criteria and found to be at a TRL 3 (-). Based on the [Ref. 1] report, these functional systems have not yet been either sufficiently demonstrated and / or some design analysis (thermal analysis) is required to move them to a TRL 4 and 6 level.

The [Ref. 1] report concluded that a “cold mock-up demonstration” along with “refined thermal analysis” would quickly drive the DOE-CTEs towards a TRL 4 and 6 level.

2.2 Technology Heritage The technologies employed by the MCSC Project are routinely used in the NPP industry for interim storage of SNF. These technologies are considered mature for this application. Reference 6 provides a listing of the commercial locations these technologies have been used, along with applicable NRC

CHPRC-03403, Rev. 0

certificates of compliance (CoC). With exception of the “relevant” environment discussed in Section 2.1.1, these technologies are considered mature for the MCSC Project.

Regarding system design (and associated technologies), the project is taking an existing and commercially available, NRC-licensed SNF DCSS system and adapting it to accommodate the MCSC capsules. Some design changes will be made to reflect unique capsule dimensions, thermal and radiation levels.

2.3 Current Project Activities and Technology Maturation This TMP was prepared to address specific technology, and system demonstration and design activities needed to bring the immature CTEs identified by the MCSC-TRSA and DOE-TRA to a TRL 6 level.

2.4 Management of Technology Maturity The CH2M Hill Plateau Remediation Company (CHPRC), Richland, WA, is responsible for managing the activities identified in this TMP. MCSC Project Engineering will manage and provide oversight for all TMP activities including those that may be subcontracted. The activities identified herein will be tracked on the MCSC Project schedule.

3 TMP This section describes the specific activities planned for the MCSC-TRSA and DOE-TRA CTEs requiring maturation, demonstration and analysis.

3.1 Development of Technology Maturation Requirements 3.1.1. MCSC-TRSA Based on the design at the time the MCSC-TRSA was conducted, CTE No. 2A_2B was assessed to not have been adequately demonstrated in the relevant environment, that is, the WESF G Cell where welding will be performed under fully-remote and time-constrained conditions. The concern is with reliability. This technology is prone to some process and equipment upset, but when applied in an environment where physical access to the weld joint is possible, resolution of these upsets can be accomplished in a reasonable and timely manner. Addressing these upsets under fully-remote operations however, will significantly impact the ability (and time) to efficiently resolve issues.

To address reliability concerns in the relevant environment, the project identified the following four welding improvement options:

1. Welding Technology Optimization – Technology Development

2. Failed Weld Consequence Mitigation – Operations Investigation

3. Solid State Welding Technology – Technology Development

4. Containment Closure Welding in Truck Port vs. G Cell – Programmatic Investigation

In response to the CTE No. 2A_2B reliability concerns, the MCSC Project and the CSS design contractor decided to move the closure weld from the UCS to the TSC. TSC closure welding will be performed in the Truck Port, where physical access to the weld joint can be accommodated. This effectively addresses the reliability issue with CTE No. 2A_2B technology by changing the environment to one where the technology has been successfully demonstrated – see Reference 6 for a listing of these applications. The technology, applied in an environment allowing for physical access to the weld joint, is considered to meet the required TRL 6 level.

CHPRC-03403, Rev. 0

5

With this design change, the CTE No. 2A_2B technology meets the required TRL 6 level, thus eliminating the need to perform the above welding improvement options. Therefore, no additional actions will be taken to respond to the MCSC-TRSA recommendations.

3.1.2. DOE-TRA The DOE-TRA CTEs (#1, #2 and #4) failed to meet functional system and design maturation criteria as reported in the DOE-TRA report [Ref. 1]. The concern is that the systems, and associated technology, have not been adequately demonstrated, and the thermal and heat removal design not sufficiently refined. To address these concerns, the following activities are planned:

1. Equipment Testing – to address system functionality of CTEs #1 and #2.

The MCSC Project Test Plan [Ref. 7] describes the testing that will be performed during the project. In general, factory acceptance testing (including fit testing) will be performed by equipment fabricators / vendors prior to acceptance of the equipment by the MCSC Project. On-site mock-up activities will be performed to optimize processing steps, train personnel, and develop procedures for normal and off-normal operations. Dry-run integrated testing will be performed to demonstrate readiness for operations. Additionally, dimensional checks of the capsules will be performed during the design phase to demonstrate that the capsules will fit into the UCS.

2. Thermal and Heat Removal Design – to address design refinement for CTEs #1, #2 and #4.

As the design progresses beyond the current conceptual design phase, thermal and aging management analyses will be refined. Additional design reviews are planned at the preliminary and final design stages.

The above activities will be identified in the project schedule.

3.2 Life-Cycle Benefit The benefits of using the TRA approach for technology maturation are as follows:

1. Increased confidence the technology will be ready for project insertion at the CD-2/3 phase of the project

2. Efficient and timely resolution of technology maturity issues to reduce project costs and potential delays in the project schedule

3. Increased confidence that production transfer operations, including loading and welding of UCSs, will meet the overall project schedule

The cost of implementing a TRA maturation process, to ensure project technologies are mature and successfully perform their intended function, is small compared to the cost of potential project delays and operations re-work.

3.3 Specific TMPs 3.3.1. MCSC-TRSA CTE No. 2A_2B Section 3.1.1 discusses a change in the design subsequent to performing the MCSC-TRSA that effectively brings the CTE No. 2A_2B to the required CD-2/3 TRL 6 level. As such, no maturation activities are required for this technology nor will there be any additional actions taken to respond to the MCSC-TRSA recommendations.

CHPRC-03403, Rev. 0

3.3.2. DOE-TRA CTE #1, #2 and #4 Key Technology Addressed The DOE-TRA report identified two functional systems (CTE #1 and #2) as requiring demonstration and refined thermal analysis, and one functional system (CTE #4) requiring refined thermal analysis and a technical basis for design life extension.

Objective The objective or purpose of the three DOE-TRA identified CTEs are as follows:

1. CTE #1 – Capsule Loading System

This system and associated technologies will retrieve capsules from the pool and load them into the UCS. Activities include UCS drying, inert gas backfilling, welding, testing and examination, along with the potential need for local cooling of capsules in the G Cell. The technologies associated with this system are mature and have been previously demonstrated in other applications in industry [Ref. 6]. It is important however, to ensure that the specific configuration of the capsule loading system technologies “work together” and that thermal analyses adequately consider the need and ability to maintain capsule design temperatures.

2. CTE #2 – UCS Insertion into TSC and Cask

This system and associated technologies will transfer the loaded UCS from the G Cell to the Truck Port for insertion into the assembled TSC / VCC. Activities include UCS transfer from G Cell to the Canyon using the Dry Transfer System (DTS), UCS insertion into the TSC using the Shielded Indexer Plate (SIP), and miscellaneous equipment – rigging, lifting and handling equipment. The technologies associated with this system are mature and have been previously demonstrated in other applications in industry [Ref. 6]. It is important however, to ensure that the specific configuration of the system technologies “work together” and that thermal analyses adequately consider the need and ability to maintain capsule design temperatures.

3. CTE #4 – Extended Storage at CSA

This system and associated technologies will monitor cask system temperatures to ensure capsule temperature requirements are met over the design storage term. Canister (TSC) aging management and strategy are also a part of this system. The technologies associated with this system are mature and have been previously demonstrated in industry [Ref. 6]. There is however, opportunity to further develop the bases for long-term aging and thermal management.

Current State of Art The technologies associated with CTE #1, #2 and #4 are routinely used for commercial SNF DCSSs. The MCSC Project CSS will be similar to the SNF systems; however, there will be some differences in design to accommodate unique capsule dimensions, thermal and radiation levels. The MCSC Project completed conceptual design for the capsule CSS in late 2017 and is currently (as of early 2018) performing preliminary design.

This TMP outlines the activities (design and system demonstration) required to address the maturity gaps identified for CTE #1, #2 and #4.

Technology Development Approach Based on review of the DOE-TRA report [Ref. 1], MCSC Project Engineering prepared a listing of the DOE-TRA identified gaps and recommended actions. Attachment C provides the following:

Sect. 3.4.3 / CTE #4 The thermal analysis should be revised with realistic assumptions to inform design of the casks, internals, and the concrete pad.

Thermal analysis will be performed and refined during CSS preliminary and final design.

CSS final design is scheduled to complete in September 2018.

6 “The simplifying assumption that the ambient temperature is 94°F, and neglecting solar load, is not realistic or bounding.”




7 “The ends of the cask were treated as adiabatic, which is not representative in terms of forecast heat load to the Interim Canister Storage Pad concrete, solar load to the container, or natural ventilation cooling and heat transfer design information regarding the components within the canister.”




8 “The thermal analysis included a result that predicted a component interference fit due to differential thermal expansion between the stainless steel and aluminum components, but no stress analysis could be located to verify that this had been addressed in design.”




9 “The cask selected for this project has a design life of 50 years, yet the project requires a 100 year design life. The team was not able to locate a technical basis for the 50 year extension in design life.”

Sect. 3.4.3 / CTE #4 NA Will clarify discrepancy in design life during CSS preliminary and final design.


10 “The truck bay heat load is not yet modelled, but with the current low ventilation airflow the heat load associated with a full cask would result in approximately a 70°F temperature rise, resulting in a 140°F leaving air temperature, assuming perfect mixing. It is likely that the cask and basket area would be significantly hotter.”

Sect. 3.4.3 / CTE #4 A recirculating cooling system will be required and flow should be pulled from near the cask to ensure maximum convection heat transfer.

Thermal analysis will be performed and refined during CSS preliminary and final design. If required, a supplemental cooling system will be designed as a part of the WESF Modifications design.

CSS final design is scheduled to complete in September 2018. WESF Modifications design activities are expected to complete in 2019, pending funding availability.

11 “The team also recognized opportunities to address capsule temperature monitoring challenges in Interim Canister Storage Pad design.”

Sect. 3.4.3 / CTE #4 Suggest arranging all casks within line of site of the fence line, such that an infrared camera could be utilized to periodically check temperatures, should instruments fail.

This will be considered during CSS preliminary and final design. The cask arrangement specified during conceptual design was chosen to minimize radiation dose at the CSA fence. The CSA will be accessible during normal operation.


12 “Canister and cask cooling technology and components have been certified for use in the nuclear industry [NRC Certificate of Compliance No. 72-1025] and successfully demonstrated in a commercial NPP DCSS environment. However, the technology has not been demonstrated for long-term aging management.”

Sect. 3.4.4 / CTE #4 NA Aging management design and strategy will be performed and refined during preliminary and final design.

Sect. 3.4.5 / CTE #4 A refined thermal analysis and technical basis of design life extension of CTE #4 “Extended Storage” would drive CTE #4 towards TRL 4 and TRL 6 quickly.

Thermal analysis will be refined and design life analysis will be performed during CSS preliminary and final design.


14 “The integrated Waste Processing System (WPS), was found not to be at TRL 4 by the TRA Team … The CTEs were all found to be at TRL 3(-). Therefore, the integrated WPS was found to be at TRL 3(-).”

Sect. 3.5 This finding is a direct result of the fact that none of the three CTEs identified by the TRA Team was found to be at TRL 4. (Mature the CTEs and the WPS TRL will mature as well)

This will be resolved when other gaps are resolved. No specific action will be taken.

15 Lack of TRL maturity Sect. 4.2 The TRA Team recommends that the project regroup the identified TEs from TRA Self-Assessment according to functional system.

The MCSC Project will not update the TRSA performed at the conceptual design. Application of 413.3B requirements to the MCSC Project are currently under review due to a recent revision of 413.3B and redefinition of the capital asset project portion of the Project. If a future TRSA is required, it will consider this recommendation.

If a future TRSA is required, it will be performed after the CSA, WESF Modifications, and CSS preliminary design are complete. According to the current schedule, the earliest the TRSA would start is August 2018.

16 Lack of TRL maturity Sect. 4.2 The project should then re-evaluate the new TEs to determine CTEs and perform TRL 3, TRL 4 and TRL 6 calculator evaluations.



17 Lack of TRL maturity Sect. 4.2 The project should then develop a technology maturation plan (TMP) to address the gaps between TRL 3 and TRL 6.

18 Lack of TRL maturity Sect. 4.2 Team also recommends that thermal analysis be refined to better understand heat transfer requirements, and that a technical basis for the 100 year life be developed, allowing sufficient time for operations and to further develop design.

Thermal analysis will be refined and design life analysis will be performed during CSS preliminary and final design.


19 Lack of TRL maturity Sect. 4.2 A time and motion study should be performed on the integrated process, factoring in thermal limits, to establish capsule inventories in G Cell and the Truck Port and to evaluate impact of component failures on throughput and define recovery operations.

A time and motion study will be performed to refine operational activities, to include thermal constraints during CSS preliminary and final design.
