Statement of Task The National Academies of Sciences, Engineering, and Medicine (NASEM) shall assemble a committee to provide guidance to the U.S. Department of Energy, and others, that are aligned with the objective of constructing a pilot plant in the United States that produces electricity from fusion at the lowest possible capital cost (Pilot Plant).
The committee shall provide a concise report that addresses the following points:
Establish key goals for all critical aspects of the Pilot Plant, independent of confinement concept and during each of the plants anticipated phases of operation.
Identify the principal innovations needed from both the private sector and government to meet those key goals.
Seek input from potential future owners of power plants and potential manufacturers of fusion power plant components.
Characterize the energy market for fusion and provide input on how a fusion pilot plant could contribute to national energy needs.
NOTE: TASK STATEMENT PARAPHRASED TO FIT ON SLIDE
Key Takeaways Recommendation: For the United States to be a leader in fusion and to make an impact on the transition to a low-carbon emission electrical system by 2050, the Department of Energy and the private sector should produce net electricity in a fusion pilot plant in the United States in the 20352040 timeframe.
Recommendation: DOE should move forward now to foster the creation of national teams, including public-private partnerships, that will develop conceptual pilot plant designs and technology roadmaps that will lead to an engineering design of a pilot plant that will bring fusion to commercial viability.
==
Conclusion:==
Successful operation of a pilot plant in the 20352040 timeframe requires urgent investments by DOE and private industry both to resolve the remaining technical and scientific issues, and to design, construct, and commission a pilot plant.
Role of the Pilot Plant:
Future Electricity Generation Market Firm low-carbon/non-carbon electrical energy generation will be needed to decrease the cost.
Utilities foresee a transition to low-carbon electrical generation by 2050.
Strategy and Roadmap
Pilot Plant Design Considerations for Phase 1 Phase 1a
-target 100-500 MW time-averaged thermal power for 100 s
-for pulsed concepts, operate at the design repetition rate for Phase 2 Phase 1b
-for D-T fusion, demonstrate production, extraction, and refueling of tritium on a timescale sufficient to maintain reasonable operations
-for pulsed concepts, these should be for a comparable time scale of 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> at the design repetition rate for Phase 2 Finding: The need for sufficient tritium self-production in a pilot is because the available worlds supply of tritium is of the same order as a D-T pilot plants annual tritium consumption. A D-T pilot plant operator will need to procure sufficient tritium to startup the facility.
Goals for a Fusion Pilot Plant:
Considerations for Phases 2 and 3 Phase 2 demonstrate operation for an environmental cycle including maintenance require operation on the order of one full power year Phase 3 demonstrate and improve average availability for commercial fusion provide additional data on the mean time to failure and replacement time for materials/components use for testing advanced materials and technology and novel deployment of fusion to the grid
Demonstration of safe operation of the fusion pilot plant is one of its most important goals.
Tritium dominates the source term and mitigation of tritium release is key Experience with JET and TFTR operations and ITER design exists Goal of pilot program to have < 1 kg of tritium on site Full scale plant would have more tritium Neutron activation of structural materials can be mitigated by material choice Desire to avoid greater than Class C waste in the pilot plant Demonstrate that FOAK can use low activation materials in blanket and structures Minimize volume of waste in near-surface disposal facility Obviate the need for reliance on repository, if possible Finding: A fusion pilots integrated tritium processing rate will be 10 - 100x faster per day than present experience in heavy-water moderated fission.
Recommendation: DOE should establish and demonstrate efficient tritium processing technologies at relevant rates and processing conditions before operation of a pilot plant.
NRC is required to develop a regulatory process for fusion by Dec. 31, 2027 Meetings are underway and exploring three regulatory framework approaches:
Utilization facility with Part 50 - reliance on exemptions Byproduct material - assumes fusion can be considered an accelerator Hybrid approach -- uses parts of both through rulemaking Recommendation: NRC should establish the regulatory framework, including the decommissioning stage, of fusion power plants as well as the pilot plant.
Finding: A regulatory process that minimizes unnecessary regulatory burden is a critical element of the nations development of the most cost-effective fusion pilot plant.
A flexible regulatory framework is necessary to accommodate different designs and to keep pace with innovation
Key Regulatory Issues Radiological protection - presence of tritium and activation products Tritium management - existing practices and pilot recommendation to keep levels < 1 kg Siting and EP - design specific issue, depends on release likelihood and source term Decommissioning - dont believe any unique issues are presented with fusion Waste steam - greater than Class C disposal depends on Part 51 rulemaking Agreement state authority - if byproduct material framework used Licensed operators - not handled in Part 30, design specific issue Finding:
Existing nuclear regulatory requirements for utilization facilities (10 CFR Part 50) are tailored to fission and not well suited for fusion Finding: Regulatory framework for radiation protection and byproduct material provided under 10 CFR Parts 20 and 30 is well suited to fusion

2 The Social Acceptance Challenge
Motivation: A Lack of Social Acceptance is a Risk to Fusion 3
Examples of technologies that face this risk:
- 1. Genetically modified food1
- 2. Facial recognition
- 3. Vaccines2
- 4. Fission3 A lack of acceptance increases capitals costs, litigation costs and risks, and regulatory burdens4 1.

A Cautionary Fission Example: The Muria Nuclear Power Plant 4
In July 2006, Indonesian government proposed four 1 GW reactors near the village of Balog, on the Muria peninsula1 In September 2007, the Nahdlatul Ulama, the largest traditionalist Islamic organization in Indonesia, determined that the reactors were forbidden under Islamic jurisprudence:
- 1. Radioactive waste & local impacts, particular from thermal load to fish
- 2. Business model
Transferred profits abroad, while Indonesia bore the risk and expense of decommissioning
Ongoing dependence on foreign expertise and materials 1.

Neither fusion nor outreach/education would have likely been persuasive
The Social Acceptance Challenge for Fusion 5
Fusion that is not social accepted may face the same challenges as fission Technical distinctions between fusion and fission may not be enough, on their own, to secure fusions social acceptance Social acceptance may be just as important as key technical and economic milestones, such as net energy production, for climate change mitigation Fusion has an opportunity to distinguish itself from other energy technologies, not just in how it uses physics, but also in how it approaches social acceptance
Two Established Methods to Achieve Social Acceptance 6
1.
A Social License1 A process of acquiring societys consent to a particular project or endeavor Long history of successful analysis and application Applied to project siting, extractive projects, ecological research, genetic engineering research, etc.
2.
Ethical Review Committees2 40-year application to controversial biomedical technologies Global adoption and global literature pertaining to diverse ethical perspectives Focus on non-technical perspectives 1.

Neither approach is exclusive - both approaches complement each other
7 Social License Approach
Features of the Social License Method 8
A two-way process that opens expertise to new questions and perspectives:1 More than education, public relations, or letting the public see the experts at work2 Project proponents have to learn from and meaningfully consider input from non-experts Addresses what people actually worry about, rather than what they should worry about Creates a sense of procedural justice, even for opponents of a particular activity3 Acts as a form of peer review that generally improves outcomes for proponents and society4 1.

Relationship between Social License and Legal License 13 Regulatory compliance is necessary, but not sufficient, for a social license1 Legal license can help by:
Addressing health and safety concerns Facilitating meaningful engagement and transparency Regulatory frameworks can hinder social acceptance:
Foreclose meaningful engagement and/or transparency Undercut confidence in health and safety Undercut trust by giving the impression of a hidden agenda Regulatory agencies generally do not have responsibility for a social license Social License Legal License 1.

Relationship between Ethical Review and Regulatory Agencies 17 There is a time gap between the ethical review and adoption of the reviews recommendations by regulatory agencies Recommendations are often respected prior to formal legal adoption as guidelines for companies and researchers Neither regulatory agencies nor regulated entities typically undertake ethical review
18 Summary of Social Acceptance Insights for the Development of a Regulatory Framework for Fusion
Insights for the NRC 19 NRC should likely not see itself as responsible for either a social license or ethical review Social acceptance is more likely to be facilitated if NRC does not advocate for fusion With social acceptance in mind, the regulatory framework should:
Give the NRC the authority and capacity to manage the full set of likely public concerns Put public engagement front and center in the development and implementation of the framework Maximize transparency and presume disclosure rather than non-disclosure Be flexible so that it can respond to changes in both public concerns and the underlying fusion technology Framework should be easy to implement, for both NRC and regulated entities
Insights for the Public 20 Engage in these meeting and use them as an opportunity to share concerns to both the NRC and the fusion companies Ask colleagues to participate If you have concerns, think of ways that the NRC or companies could productively address them
Insights for the Fusion Community 21 View the development and implementation of the regulatory framework as a process of convincing the public that fusion is safe Help the NRC identify the publics concerns Help the NRC develop flexible, practical and confidence-inspiring mechanisms for addressing these concerns Follow the Oxitec, Finnish and Swedish examples and avoid the Yucca Mountain experience:
View regulatory compliance as critically necessary, but not sufficient for social acceptance Avoid an exclusive focus on health and safety for social acceptance Encourage public engagement and maximize transparency Participate in ethical review
Proposal for a Process of Developing the Regulatory Framework Focused on Public Concerns 22 Public Comment Regulatory Mechanism Catalogue of
- Public Concerns
- Health, Safety and Proliferation Risks For each concern
/risk Is this risk/concern addressable by the NRC?
If so, whats an effective, practical, flexible and confidence-inspiring mechanism to address the concern/risk?
Regulatory Framework Expert Analysis Public Comment Expert Analysis Mechanism 1 Mechanism 2 Mechanism N This process would:
Focus the framework on public concerns, rather than expert concerns Provide a forum for airing public concerns that the fusion community may need to address outside of NRC regulation

Developers Perspectives on Potential Hazards, Consequences, and Regulatory Frameworks for Commercial Deployment
Building the Fusion Economy Fusion energy will revolutionize the global energy system. It can solve the climate crisis and build energy abundance.
Fusion must be deployed fast enough to meet the worlds challenges.
The Fusion Industry Association is accelerating commercially viable fusion energy by advocating for policies that support our 24 member companies as they develop commercial fusion power.
The FIA is building a movement to tell the world should know how important clean, safe, affordable, and secure fusion will be to the future energy system. The FIA is educating key stakeholders in the private, public, and philanthropic sectors about the importance of tomorrows fusion power economy.
Mission of the FIA The Fusion Industry Association is the voice of the growing fusion industry. It supports efforts to accelerate commercially viable fusion research and development. The Association promotes the interests of the fusion industry around the world by advocating for ways to commercialize fusion power on a time-scale that matters.

Fusion is different from Fission
Fusion is different from Fission
- No Chance of Meltdown Fusion energy devices do not use any special nuclear material or source material, creating a much lower risk profile than fission facilities, thus, criticality or meltdown accidents are physically impossible
- Minimal Safety Risk to the General Public With reasonable design, construction, and operations procedures, fusion energy generating facilities would not create a credible safety risk to the general public (i.e., that requires an evacuation of members of the public near the fusion energy generating station) that is any greater than hydrocarbon power plants or other comparably sized industrial facilities
- No long-lived, highly radioactive waste The waste output from a fusion facility consists of helium plus small amounts of solid, slightly activated device components and other materials that can easily be disposed of as low-level waste.
FIA Regulatory Goal U.S. policymakers should establish a broad legislative and regulatory framework that explicitly and permanently removes fusion energy from the regulatory approaches that the federal government has taken towards fission power plants.
A Different Approach than Fission
- The NRCs Part 50, 52 and proposed 53 regulations for large commercial fission reactors address a different suite of risks compared to risks that fusion facilities could create and therefore are not appropriate for fusion systems.
Fusion is already Regulated
- Rules like the NRCs Part 20 regulations for general radiation protection and Part 30 rules for handling byproduct material properly address fusion facilities risk profiles.
Fusion Regulation Proceeds under existing rules
- Under the Energy Reorganization Act of 1974, the Department of Energy governs aspects of nuclear weapons and energy development, while the NRC regulates civilian nuclear safety and public health.
- Agreement States are already providing sufficient regulation to ensure safety in fusion devices around the country.
- Private fusion facilities are already licensed in Agreement States under the NRCs Part 20 regulations for general radiation protection and Part 30 rules for handling byproduct material.
What is the Industry NOT Asking for?
Fusion Fission Hybrids Regulation of DoE Experiments
There are No Commercial Plans for ITER-scale Machines
- The large scale of an ITER/DEMO machine would challenge Agreement States
- Significant tritium requirements (e.g. 5-15 kg)
- Large scale will result in large amount of activated materials and low-level waste
- Most of the academic literature and DoE expertise is focused on machines at these scales
National Academies Roadmap to a Pilot Plant
- Recommendation: The Department of Energy should move forward now to foster the creation of national teams, including public-private partnerships, that will develop conceptual pilot plant designs and technology roadmaps and lead to an engineering design of a pilot plant that will bring fusion to commercial viability.
FIA Will Work Collaboratively with NRC
- A deliberative process would allow for the NRC to gain a better understanding of the nature of technology and risk.
- The current licensing regime provides comprehensive and appropriate standards for all conceivable private approaches within the current decade.
- 2009 NRC guidance said that an evaluation of technical and legal issues related to regulation of fusion would likely span several years and would commit the NRC to expend significant resources to develop a regulatory framework for fusion energy.
- The FIA will work collaboratively over the coming years to help develop any new framework thats needed.

- Most of the literature available on describing tritium requirements, low-level waste generation, safety and other topics related to fusion energy generation facilities is exclusively focused on ITER/DEMO sized facilities
- No private companies are pursuing ITER/DEMO sized facilities so this literature can lead to incorrect conclusions based upon the much larger scale of these public facilities compared to private approaches
- Recognizing the importance of social acceptance, private fusion approaches have been selected to require orders of magnitude less tritium, produce much less low-level waste (LLW) and not require emergency off-site evacuation planning
- The scale (tritium inventory, waste generation and safety) of CFSs ARC and other proposed private facilities is similar to accelerators and research/medical facilities which are already effectively regulated under 10 CFR 30/20 Introduction

- If power is cut or vacuum chamber fails, facility simply shuts down, no irradiated fuel decay heat to deal with
- No possibility of a melt-down nor production of long-lived nuclear waste due to the lack of source or special nuclear material

- Direct Dose: Operation of the plasma generates neutrons and X-rays - the direct dose Carries the energy of the fusion reaction and deposits it in the materials around the vessel and thus providing most of the power that is eventually sold Can be effectively shielded by materials with existing materials Only present when the plasma is operating and fusing
- Activated Material: Neutrons create activated materials in the vessel around the machine Materials that provide the shielding of neutrons are transformed by stopping the neutrons - we purposefully select materials for their minimal activation properties and strength Activated materials build up over time as the machine is operated and represent a much lower dose (~10,000 times) than the direct dose Components that become activated can be disposed of as low-level waste at the end of life as given in the decommissioning plan or maintenance scenarios Even aneutronic fuels generate significant neutrons from secondary reactions
- Tritium: Tritium is the main radioactive material of concern, and exists predominantly within the vacuum vessel, blanket loop and fuel handling systems All fusion systems have to handle tritium, even the advanced or aneutronic fuels, since tritium is a product of their fuels in lower but still significant amounts Fuel handling systems are put inside a glovebox to provide additional protective barriers Plasma operates at a vacuum, so if the vessel is breached, air rushes in and tritium does not go out Monitoring of the release of the gas is done via monitors on the stack Fusion Hazards Direct dose emanates from inside vacuum vessel and deposits neutrons and X-rays into vessel wall, blanket and surrounding shielding which creates activated materials Blanket loop (blue)

- Private fusion facilities and CFSs high-field approach in particular, allows for significantly smaller fusion energy facilities and hence smaller LLW volumes
- For CFSs design, most of this LLW volume is expected to be Class A which allows for shallow land burial and no Class C
- LLW volumes and characteristics are similar to what is already produced at existing accelerators and research/medical facilities Low Level Waste Generation Private fusion facilities will have 5-12 times smaller LLW volume than ITER/Demo!
Note: Power Core Volume includes blanket, divertor, shield, manifolds, vacuum vessel, magnet, and structure.

- Relative simplicity of tritium recovery in an immersion blanket where the material holding the tritium (e.g. molten salt) is circulated out
- Lower thermal power compared to DEMO
- There are commercial research suppliers located in the middle of major urban areas who are licensed for maximum tritium inventories up to 10 g under 10 CFR 30 that have safely handled tritium for decades Tritium Inventory Requirements Already licensed under 10 CFR 30/20 Private fusion facilities will have

- The table shows the radiation dose limits to the general public for Agreement States (NRC Part 30 type licensees)
- If a facility can be designed to stay under these limits, then no off-site emergency evacuation planning needs to be conducted to protect public health and safety
- Privately developed fusion energy facilities can be designed to stay under these limits using a combination of these well-established strategies:
- Set-back of the site boundary
- Break up the tritium inventory to smaller amounts so that the actual releasable inventory is a small percentage of the total inventory
- Selection of appropriate materials and barriers
- The fusion industry is working to stay below the dose limits of 10 CFR 30/20 Radiation Dose Limits Mode Dose Pathway to Off-site Public Regulatory Limit or Guideline (mrem)

- Broadly, the fusion community identified Loss of Vacuum as the highest priority radiological safety scenario Vacuum vessels contain small amounts of tritium fuel and a breach creates the potential where some fuel could flow out
- The JET safety analysis case assumed ~10% of the tritium in the vacuum vessel was releasable
- In this scenario, since the vessel is at vacuum, air would enter at a faster rate than the diffusion of tritium out of the vessel and the torus pumps would collect the tritiated inventory for processing and clean-up
- The risk of this scenario can be mitigated by including the following features:
- Design tritium confinement systems with sufficient redundancy and layers of protection that no single failure can cause a significant tritium release
- All tritium system components are housed within negative pressure, helium atmosphere gloveboxes which are furnished with an associated clean-up and tritium recovery system in the event of a release to the secondary glovebox confinement
- Design torus pumps to easily achieve the necessary decontamination factors for any expected torus breach
- Prior experience with component failure and clean-up indicates that these clean-up systems are capable of containing leakage from equipment failure with actual observed decontamination factors greater than 1000 Safety Analysis Example

- Private fusion approaches can be designed to require orders of magnitude less tritium than ITER/DEMO, produce much less low-level waste (LLW) and not require emergency off-site evacuation planning
- The characteristics of CFSs proposed fusion energy approach with regards to tritium inventories, LLW generation, and safety are similar to other privately proposed facilities
- The scale of private fusion energy facility tritium inventories and LLW generation is also similar to current research accelerators and medical facilities which are already effectively regulated under 10 CFR 30/20

- State becomes responsible for:
- licensing, inspection, and enforcement of medical, academic, and industrial uses of certain radioactive materials
- responding to certain types of incidents and allegations within their borders 13
National Materials Program (NMP)
The NMP provides a coherent national system for the regulation of agreement material with the goal of protecting public health, safety, security and the environment through compatible regulatory programs. Through the NMP, the NRC and Agreement States function as regulatory partners.
NRC and Agreement State work together on:
- Development of regulatory guides and procedures
- Development of regulations
- Integrated Material Performance Evaluation Program (IMPEP)
Adequate and Compatible 14
Adequacy and Compatibility
- Adequate to protect public health safety and security
- Compatible with NRC requirements
- State program does not create conflicts, duplications, gaps, or other conditions that jeopardize an orderly pattern in the regulation of agreement material (source, byproduct, and small quantities of special nuclear material) on a nationwide basis.

Discussions of Possible Frameworks for Licensing/Regulating Commercial Fusion
Considerations for Part 30 Licensing of Fusion Energy
Basis for the License
- Design and hazard analysis will determine the scope of requirements needed for a license for the safe use of radioactive materials
- Regardless of the regulatory approach, similar information will be needed to evaluate the design and radiological hazards associated with a commercial fusion facility
- The NRC Commission will make the final decision on the regulatory framework prior to the start of any rulemaking for fusion energy systems
Basis for the License Design Requirements
- 1. What is the overall design for the fusion facility?
- 2. How will the facility be constructed?
- 3. What codes and standards will be used for critical systems, structures, and components?
- 4. How will critical systems, structures, and components be environmentally qualified?
- 5. What acceptance testing will be performed for systems, structures, and components prior to initial operation?
Basis for the License Hazard considerations 1.
What are the hazards associated with this fusion facility?
2.
How likely is it that any of these hazardous conditions will occur?
3.
What are the consequences if one of these hazardous conditions occurs?
4.
What type of defense-in-depth will exist for critical safety systems, structures and components?
5.
What mitigating systems, structures, or components will exist for hazardous conditions identified (e.g., interlocks, shielding (primarily neutron), fire protection, worker and public safety protection)?
o For example, what are the safety systems required to prevent the accidently release of tritium?

activation products will increase over time. How will this be controlled to ensure that maximum possession limits are not exceeded?
- What is being activated - is the neutron shielding preventing activation outside the plasma chamber?
- Emergency plans (if required)
- Regulations require an evaluation of off-site consequences with over 2 grams of tritium and require a plan if greater than 1 rem
- What are the pathways and potential release scenarios?
- What do you believe needs to be in the emergency plan?
Questions on Licensing Fusion Systems
- Financial Assurance and Decommissioning
- How will you determine the amount of activation products to determine the amount of financial assurance needed?
- How do you plan to decommission the facility?
- Training
- What should be the requirements for an individual operating a fusion energy plant?
- Who will periodically evaluate the performance of the operator?
Questions on Licensing Fusion Systems
- Radiation Safety Program
- Tritium is challenging to monitor and measure - what equipment and what frequency will be used to routinely measure tritium?
- What are the energies of the neutrons typically present?
- How will you ensure that personnel are protected during operations?
- What radiation hazards will workers at the fusion facility be exposed to during operations and what type of monitoring of these workers is anticipated?
Questions on Licensing Fusion Systems
- Waste management

- What is the lifespan of the components at the facility that become activated? Will they need to be replaced periodically? Where will they be securely and safely stored onsite or will be shipped offsite immediately for disposal?
- Environmental protection regulations
- What considerations are needed to address the requirements in 10 CFR Part 51?
- Should fusion facilities be considered categorically excluded per 10 CFR Part 51.22?

Background===
SECY-09-0064 April 2009
- Request for the Commission to establish Regulatory Jurisdiction over commercial Fusion systems. In summary:
- 1. Maintain Status Quo, or
- 2. Commission asserts (or not) jurisdiction over commercial Fusion systems.
SRM SECY-09-0064 July 2009
- Commission approved staffs option 2: the NRC has regulatory jurisdiction over commercial fusion energy devices whenever such devices are of significance to the common defense and security, or could affect the health and safety of the public.
- The staff, however should wait until commercial deployment of fusion technology is more predictable, by way of successful testing of a fusion technology, before expending significant resources to develop a regulatory framework for fusion technology.

Background===
Nuclear Energy Innovation and Modernization Act (NEIMA) was signed into law in January 2019 and requires the NRC to complete a rulemaking to establish a technology-inclusive, regulatory framework for optional use for commercial advanced nuclear reactors no later than December 2027 o

Regulatory Approaches Preliminary assessments left open the regulatory approach for commercial fusion reactors Possible approaches include treatment similar to:
Hybrid Approach
- 3a-Within current framework (fragmented):
- 3b-Within a dedicated Fusion framework (consolidated):
Hybrid Approach
- Risk-Informed, Performance based approach,
- Technology-Inclusive for various Fusion systems (fuel types and facility designs), and
- Graded and scaled approach that balances requirements against hazard/risk and consequences.
Key Elements for Development of Hybrid Approach
Integrated, Risk-Informed Approach Bow-Tie Risk Management Figure 38 (e.g., release of radionuclides)
(e.g., internal failures, external events)
(e.g., protective actions, siting restrictions)
(e.g., dose to public)
Hybrid Approach - Performance Based Categorization
- Design criteria in conjunction with safety objectives/requirements would form the basis and allow for a performance-based, graded regulatory approach commensurate with technology.
- Well defined safety objectives/requirements would promote regulatory stability, predictability, and clarity by allowing for a systematic and predictable classification of Fusion systems.
- For example:
In NPPs (Proposed rulemaking for scalable emergency planning zone)
In RTRs (For RTRs licensed to operate at 2 megawatts (2,000,000 watts) or greater, the inspection program is completed annually. For reactors licensed to operate at power levels below 2 megawatts, the inspection program is completed biennially (every two years).
In DOE facilities (DOE-STD-1027-2018 provides requirements and guidance for determining if a Department of Energy (DOE) nuclear facility is a Hazard Category (HC) 1, 2, 3, or Below HC-3 nuclear facility based on hazard consequences.)

5 A Graded Approach is...
- Risk-Informed: Different levels of regulation based on actual risk levels
- Performance Based: Performance metrics can inform regulatory tiers
- Enabling for State Partners: States are the experts today in regulating accelerators
- Built for the Long Term: We dont want to repeat this all in 10 years A Graded Approach & NRC Best Practices 5
6 Preliminary Considerations 6
Consideration 1: Work Up, Not Down
- Many planned private-sector fusion devices are more like accelerators than reactors
- Legally (72 Fed. Reg. 55,864 & 10 CFR 30.4)
- Technically (states regulate large accelerators, cyclotrons, and more)
- It is easier to risk-inform when starting fresh
- Working up allows states to continue to play an important role
7 Preliminary Considerations 7
Consideration 2: Performance Based Dividing Lines Potential Factors To Divide Tiers Sample Performance-Based Threshold Accident Risk Accident risk falls below the ~1 rem public dose threshold Passive management of residual heat with a high margin of safety Shielding & Safety During Operations Leverages only low-complexity, passive shielding during operation Waste Only generates and stores low level radioactive waste Proliferation Risk No reasonable path for generating special nuclear material if operated as intended with low-complexity or passive security protections Illustrative Metrics for Discussion
8 Preliminary Considerations 8
Consideration 3: Implement Differences in Process
- Rubber meets the road with the licensing process
- Timelines
- Dollars
- Certainty
- Sample process improvements based on tier:
- State licensing for lower-impact devices
- Depth of analyses (e.g., PRA) differs with tier
- Number of issues to evaluate drops with tier
9 Suggested Next Steps 9
- Build out the technical framework
- What does the community need to provide to get to year-end?
- Identify the legal path
- Identify the right path technically, then solve for legal issues
- Targeted asks of Congress as needed
- Build out the timeline to 2027
- Take advantage of the full time under NEIMA
