Advanced Nuclear Reactor Projects

New Paradigms Emerge for Innovation and Investment
in Advanced Nuclear Energy Reactor Designs

Nuclear-abstract_thumb.jpg(Updated July 2022) Designers of advanced nuclear reactors seek to bridge the gap between concept and prototype. While it is too early for investors and potential customers to easily pick winners from an increasingly crowded field of advanced reactor projects, new patterns of investment, including public/private partnerships, are creating opportunities for entrepreneurial developers. A key area of interest is in small modular reactors, e.g., with electrical power ratings of less than 300 Mw.

Key Success Factors for
Advanced Nuclear Reactor Developers

Policy Issues –  A good place to start is the report by the Breakthrough Institute How to Make Nuclear Innovative.  Read the executive summary and watch the brief video on YouTube that covers the report’s key findings. See also their newest report 

The report’s mainstream recommendations for modernizing nuclear innovation in the United States, include;

  • Licensing reform. Licensing of new nuclear technologies will need to be reformed in order to support smaller, entrepreneurial firms and to build investor confidence as key design and testing benchmarks are achieved.
  • Public-private partnerships. National laboratories will need to provide private companies with access to equipment, technical resources, and expertise in order to lower costs and promote greater knowledge spillover in the testing and licensing process.
  • Targeted public funding for R&D. Significant and sustained research funding should be directed toward solving shared technical challenges.
  • Inter-firm collaboration. Policy and funding should be designed to encourage knowledge spillover and collaboration between companies.
  • Private-sector leadership. Public investment in demonstration and commercialization should follow private investment and avoid early down-selection of technologies.

This report uses a high-resolution nationwide model of the United States electricity sector to demonstrate how advanced nuclear reactors might play a major role in a least-cost plan to transition the power grid entirely to clean energy sources by 2050.

Investing in Advanced Nuclear Energy Firms

Due Diligence for Advanced Nuclear Technology Companies: A Guide for Potential Investors This NIA report is an introductory guide for potential investors in companies developing advanced nuclear technologies for electric power generation, industrial or district heating, hydrogen production, or other applications. The guide describes advanced reactor characteristics and considerations that may be of particular interest for evaluating investments. The focus of this guide is on fission technology, not fusion. (October 2021)

ESG Frameworks and Advanced Nuclear Energy   This new publication by NIA provides an introduction to Environmental, Social, and Governance (ESG) frameworks and how they may affect advanced nuclear energy technologies and projects. It includes potential actions the nuclear industry and financial community should consider to promote consistent analytical treatment of nuclear energy within ESG frameworks and efficient access to capital for nuclear investments. As a practical matter, until a firm has reportable earnings of over $50M/year, ESG ratings agencies aren’t going to pay attention. Also, there are multiple issues over which set of standards a firm should use to prepare an ESG report. See coverage of these issues on this blog. (March 2022)

Regulatory Issues for Advanced Reactors

nrc-logo_thumb.jpgThe Nuclear Regulatory Commission (NRC) in 2020 approved a new approach to licensing non-light water reactor technologies. The new guidance is expected to significantly reduce the regulatory uncertainty challenging the industry, while streamlining the advanced reactor design and licensing processes that have been slowed down for years due to longstanding and unresolved regulatory policies.

The new process is the direct result of a 4-year Licensing Modernization Project (LMP) supported by the U.S. Department of Energy. The project was coordinated through the Nuclear Energy Institute and led by Southern Company and industry experts.

The finalized approach focuses on a risk-informed, performance-based review process that takes into account more realistic scenarios that the developer must account for. The approach is also tailored to the unique aspects of each advanced reactor design, allowing for a clear and consistent review of its safety case. The guidance focuses on identifying licensing basis events; categorizing and establishing performance criteria for structures, systems, and components; and, evaluating the safety margins of advanced reactor designs.

Cost Reduction Drivers
OECD/NEA InfoGraphic

OECD/NEA latest study (2020) on nuclear construction costs identifies eight cost reduction drivers that can be exploited at different stages of nuclear construction. These include government support for robust and predictable market and financing frameworks, as well as policy support mechanisms for design maturity and regulatory stability.

Implementing these cost reduction drivers should also attenuate the technological, organizational and regulatory risks associated with new nuclear plant deployment.
