Regulatory Oversight of Nuclear Construction

“Change is hard because people overestimate the value of what they have and underestimate the value of what they may gain giving that up.” People continue to ask, “why is South Korea is so much more efficient at advancing new nuclear technologies? Let’s focus on just one of the root causes… regulatory oversight processes. 👉 KINS serves as the primary regulatory body for nuclear safety in S. Korea, which centralizes the licensing process allowing for more cohesive decision-making and communication. The NRC's structure involves multiple layers of approval and oversight, which leads to longer review times and more complicated interactions among various agencies and stakeholders. 👉 KINS has established standardized guidelines and checklists for licensing applications, allowing for a more predictable and efficient review process. This includes pre-application consultations that help applicants understand requirements early in the process. In contrast, the NRC relies on a more case-by-case basis for its reviews, which results in variability of timelines and requirements, often depending on the specifics of each application. 👉 KINS has adopted advanced simulation and modeling technologies to assess safety and performance, which expedites evaluations and reduce the need for extensive physical testing. While the NRC is also exploring advanced technologies, the incorporation of these tools has been much slower, and traditional methods still dominate the review process (we are looking at you, analog systems in control rooms!). 👉 KINS has made efforts to reduce the volume of required documentation for licensing applications, focusing on ESSENTIAL safety and performance criteria. The NRC requires extensive documentation, which prolongs the review process. The emphasis on comprehensive safety assessments often result in a significant amount of paperwork regardless of its relevance to safety and security. 👉 KINS engages with stakeholders early in the process and has established forums for public input, which helps to address concerns before formal applications are submitted. While the NRC does allow for public comments, the complexities of the review process often lead to public engagement occurring after substantial decisions have been made, often times resulting in contentious debates that are resource intensive for the NRC and their licensees. 👉 KINS completes licensing reviews within a few years. The NRC's licensing process takes a decade or more, especially for new reactor designs or significant modifications to existing plants. 👉 KINS is very proactive in developing regulatory frameworks for new technologies and advanced reactor designs, allowing for more agile responses to innovations in the industry. The NRC has been much slower to adapt its regulatory framework to accommodate new technologies, which is hindering the development and deployment of advanced reactors at a reasonable cost. A gentle reminder: aim for excellence!

Britain needs nuclear power. Our nuclear projects are the most expensive in the world and among the slowest. Regulators and industry are paralysed by risk aversion. This can change. For Britain to prosper, it must. Earlier this year, the Prime Minister appointed me to lead a Taskforce to set out a path to getting affordable, fast nuclear power Britain. Our final report today sets out 47 recommendations, among them: - Creating a one-stop shop for nuclear approvals, to end the regulatory merry-go-round that delays projects at the moment. - Simplifying environmental rules to avoid extreme outcomes like Hinkley Point C spending £700m on systems to protect one salmon every ten years, while enhancing nuclear's impact on nature. - Limiting the ability of spurious legal challenges to delay nuclear projects, which adds huge cost and delay throughout the supply chain. - Approving fleets of reactors, so that Britain’s nuclear industry can benefit from certainty and economies of scale. - Directing regulators to factor in cost to their behaviour, and changing their culture to allow building cheaply, quickly and safely. - Changing the culture of the nuclear industry to end gold-plating and focus on efficient, safe delivery. If the government adopts our report in full, it will send a signal to investors that it is serious about pro-growth reform and taking on vested interests for the public good. A thriving British nuclear industry producing abundant, affordable energy would be good for jobs, good for manufacturing, good for the climate, and good for the cost of living. And it could enable Britain to become an AI and technology superpower. Britain can be a world leader in this new Industrial Revolution, but only if it has the energy to power it. Our report is bold, but balanced. Our recommendations, taken together and properly implemented, will forge a clear path for stronger economic growth through improved productivity and innovation. This is a prize worth fighting for. https://lnkd.in/eVPcVhCq

Last month many of you told me that our low-dose radiation models feel overdue for an update. Now the federal government has added its own push. On May 23, four Executive Orders instructed relevant agencies to modernize licensing, adopt science-based radiation limits, and undertake a full review of NRC regulations, including ALARA guidance, during oversight and rulemaking. The American Nuclear Society quickly assembled an expert group to map the Orders against existing science and policy. Their memo concludes: • Adopting science-based dose limits is the right goal. • Reopening the 70-year debate over the Linear No-Threshold (LNT) model would drain limited NRC resources without producing a better quantitative model. • The practical win lies in using ALARA as it was meant to be used: an optimization that balances marginal dose reduction with economic and societal benefit. Today it too often becomes automatic dose minimization, which can do more harm than good. So where might regulators and licensees start to make this vision practical? Here are some ideas: – Require cost–benefit analysis in licensee ALARA plans, using established guidance like NUREG-1530, so reviewers can quickly judge whether further dose reductions are warranted. – Strengthen inspector training to distinguish true optimization from reflexive minimization, especially when dealing with exposures near background. – Create a centralized library of ALARA case studies, aggregating existing DOE and NRC examples to give licensees real-world precedents for risk-informed decisions. – Coordinate NRC, DOE, and state regulators through a joint framework aligned with ICRP-103, so low-level radiation work is governed by consistent expectations across jurisdictions. The ANS memo offers a strong foundation: https://lnkd.in/efzzgVyW What’s your stance? Where do you see the biggest opportunity to make ALARA more reasonable in day-to-day practice?

With a number of nuclear reactors being authorized under U.S. Department of Energy (DOE) and United States Department of War authority, the ability to move efficiently from federal deployments to broader commercial deployments licensed by the U.S. Nuclear Regulatory Commission is something that companies need to think about now. Developers who want to move quickly from DOE/DoW authorization to the NRC should treat federal authorization as the front end of an NRC licensing strategy—not a parallel track. Specifically, the recently issued NRC guidance tells companies to: ✅Engage the NRC early and intentionally during DOE/DoW authorization—well before an NRC license application is filed—so NRC staff can build familiarity with the design, safety case, and codes and standards being used ✅Invite NRC staff to observe key authorization milestones (e.g., the Nuclear Safety Design Agreement, preliminary and final safety analyses, readiness reviews, and initial startup testing), recognizing NRC’s role as an observer, not a decision-maker ✅Structure DOE/DoW safety documentation with NRC licensing in mind, particularly foundational elements like system classifications, codes of record, and safety analysis assumptions that can later support NRC Safety Analysis Report content ✅Formally request NRC observation and define objectives—including what meetings, documents, or tests NRC staff should observe and what feedback is being sought—to maximize licensing value and avoid ambiguity ✅Proactively identify gaps between DOE/DoW authorization and NRC requirements, using emerging DOE–NRC regulatory crosswalks to streamline later reviews and reduce rework ✅Use federal operating experience as a licensing asset, enabling earlier issue identification and shorter NRC review timelines once an application is submitted There's a real opportunity here to significantly streamline subsequent NRC reviews after DOE/DoW authorization--but developers need to be thoughtful and strategic now in order to maximize those efficiencies. https://lnkd.in/eSiT_s7c

India shows strong intent to promote Nuclear Power Generation with new Act on Nuclear Energy – SHANTI The Proposed Nuclear Act removes monopoly, promotes private sector participation, creates a transparent licensing regime, offers clarity and capping on liability, builds a strong safety and security standard ecosystem. 1.     Private Sector Participation / Technology-Neutral Eligibility : Any company - public or private, can build, own, operate and decommission nuclear plants, ending government monopoly. 2.     Expanded scope: Licensed entities can engage in generation, fuel fabrication, transport, storage, and import/export of nuclear technology. 3.     Sensitive Functions Ring-Fenced: Strategic backend activities like enrichment beyond limits, spent fuel, and heavy water remain under sovereign control. 4.     Holistic Modern Legal Framework: Old laws repealed; 5.     Independent Regulator Empowered: AERB gets statutory backing for transparent, professional safety oversight. 6.     National Policy Direction: Government to frame Nuclear Energy Policy aligned with Electricity Policy for long-term clarity. 7.     Detailed Compliance Provisions: Inspection, investigation, and enforcement rules reduce ambiguity for operators and bring in transparency. 8.     Transparent Licence Criteria: Financial, technical, and managerial capability requirements ensure investor confidence. 9.     Specialised Dispute Resolution: Dedicated councils and Appellate tribunals ensure faster, expert handling of nuclear disputes. 10. Capped Operator Liability: Liability limits based on reactor size make financial exposure predictable. 11. Government Liability Support: Nuclear Liability Fund backs extreme events beyond operator’s capped liability. 12. Mining Permitted with Conditions: Private mining of uranium/thorium allowed up to notified thresholds; clear terms reduce uncertainty. Once passed and implemented, India would attract global investors, developers and equipment manufacturers to create one of the major markets for nuclear power generation.

The U.S. Department of Energy (DOE) has issued a notice establishing a new categorical exclusion (CX) under the National Environmental Policy Act (NEPA) for certain activities involving advanced nuclear reactors, including authorization, siting, construction, operation, reauthorization, and decommissioning.  The CX is one piece of a coordinated federal effort to accelerate deployment of advanced nuclear technologies where DOE has jurisdiction or involvement. The CX applies to advanced reactors (including certain microreactors, SMRs, and Gen III+/Gen IV designs) where DOE determines that: (1) the project’s attributes, including potential fission product inventory, fuel type, reactor design, and operational plans, reduce sufficiently the risk of adverse offsite consequences from the release of radioactive or hazardous materials, and (2) the project demonstrates that any hazardous waste, radioactive waste, or spent nuclear fuel generated by the project can be managed in accordance with applicable requirements. The CX is incorporated into DOE’s NEPA implementing procedures and remains subject to, inter alia: (1) DOE’s NEPA “integral elements,” and (2) A project-specific review for extraordinary circumstances that could require an Environmental Assessment (EA) or Environmental Impact Statement (EIS). The effective date is February 2, 2026. While categorical exclusions historically had followed a notice-and-comment process, DOE is voluntarily soliciting public comments, which are due March 4, 2026 (Docket: DOE-HQ-2025-0405 (via Regulations.gov)). For certain companies developing or financing advanced nuclear projects, this development may have implications for project timelines, federal authorizations, and risk allocation. https://lnkd.in/eGm5Y9m3

SMR IX Process of approving a new SMR follows NRC regulations (part 52 in Title 10 of the Code of Federal Regulations) in the most part (other agencies can have an impact on the approval). First step is information discussions with the NRC staff, those discussions help the applicant understand what they must do and what the process is. It is not required, but it a recommended step. The March 2024 guidance document includes: • safety Analysis Report Chapter 1 – General Plant Information, Site Description, and Overview of the Safety Analysis Chapter 2 – Methodologies, Analyses, and Site Evaluations Chapter 3 – Licensing Basis Events Chapter 4 – Integrated Evaluations Chapter 5 – Safety Functions, Design Criteria, and SSC Categorization Chapter 6 – Safety-Related SSC Criteria and Capabilities Chapter 7 – Non-Safety-Related with Special Treatment (NSRST) SSC Criteria and Capabilities Chapter 8 – Plant Programs Chapter 9 – Control of Routine Plant Radioactive Effluents, Plant Contamination, and Solid Waste Chapter 10 – Control of Occupational Dose Chapter 11 – Organization and Human-Systems Considerations Chapter 12 – Post Construction Inspection, Testing, and Analysis Program. • technical specifications • technical requirements manual • quality assurance (QA) plan • fire protection program (design) • probabilistic risk assessment • emergency preparedness • security plans • cyber security plan • special nuclear material (SNM) control and accountability • fire protection program (operational) • radiation protection program  • offsite dose calculation manual • in service inspection (ISI) and in service testing (IST) • environmental report and site redress plan • financial qualification and insurance and liability • fitness for duty • inspections, tests, analysis and acceptance criteria (ITAAC)  • aircraft impact assessment • performance demonstration requirements • Nuclear Waste Policy Act • operational programs Many of these documents can take hundreds to thousands of research and engineering models. The process of completing the documents is a multi-year effort without out major backing and support. In the guiding document (DANU-ISG-2022-01) there are no timelines for the NRC to complete reviews, or requirements fully review documents for all issues. Process part 2 coming

Yesterday, X-energy and Dow filed a major permit for a new nuclear plant. They chose a path that might seem surprising, but there are good reasons every new project seems to be going this way. The two companies submitted a 𝑐𝑜𝑛𝑠𝑡𝑟𝑢𝑐𝑡𝑖𝑜𝑛 𝑝𝑒𝑟𝑚𝑖𝑡 for their Seadrift, Texas plant using the U.S. Nuclear Regulatory Commission Part 50 licensing process. Part 50 is a two-step approach where you first apply for a 𝑐𝑜𝑛𝑠𝑡𝑟𝑢𝑐𝑡𝑖𝑜𝑛 𝑝𝑒𝑟𝑚𝑖𝑡, then come back later for an 𝑜𝑝𝑒𝑟𝑎𝑡𝑖𝑛𝑔 𝑙𝑖𝑐𝑒𝑛𝑠𝑒. This is the same route TerraPower and Natura Resources have taken for their advanced reactors. So why are today’s innovators turning to an older process instead of the newer Part 52, which combines construction and operating approvals into one license? Simply put: 𝗳𝗹𝗲𝘅𝗶𝗯𝗶𝗹𝗶𝘁𝘆 Part 52 works best with a fully locked-down design before even breaking ground. With a certified design like the Westinghouse Electric Company AP1000 or the NuScale Power SMR that might sound efficient. In practice though, design changes during construction get expensive in both dollars and delays as the license is amended. The most recent reactors built in the US, Vogtle Units 3 and 4, were submitted under the Part 52 process. Even with a certified design, these AP1000 plants ended up nearly 10 years behind schedule and more than $17 billion over budget. U.S. Department of Energy (DOE) estimates that roughly $1,600 per kilowatt - 𝗺𝗼𝗿𝗲 𝘁𝗵𝗮𝗻 𝟭𝟬% 𝗼𝗳 𝘁𝗵𝗲 𝘁𝗼𝘁𝗮𝗹 𝗰𝗮𝗽𝗶𝘁𝗮𝗹 𝗰𝗼𝘀𝘁 - 𝒄𝒂𝒎𝒆 𝒇𝒓𝒐𝒎 𝒅𝒆𝒔𝒊𝒈𝒏 𝒄𝒉𝒂𝒏𝒈𝒆𝒔 𝒎𝒂𝒅𝒆 𝒂𝒇𝒕𝒆𝒓 𝒍𝒊𝒄𝒆𝒏𝒔𝒊𝒏𝒈. Part 50 may look slower on paper, but when you’re building something that’s never been done before, it gives you the room to adapt. For these first-of-a-kind designs (and potentially projects 2 and 3), that flexibility may be key to getting them to the finish line faster. #nuclearpower #atomiceconomics #atomecon
