The Expert Finance Working Group on Small Nuclear Reactors (EFWG), an independent group convened in January 2018 by the Department for Business, Energy & Industrial Strategy, recently published its report with recommendations for a market framework to enable the development of small nuclear projects in the UK with private financing and investment. The report follows the publication of the UK government’s Nuclear Sector Deal (see Latham’s related blog post).

The EFWG report considered small nuclear projects ranging from micro-generation projects through to 600 MW reactors. In contrast to “megaprojects”, such as Hinkley Point C, which is estimated to cost almost £20 billion, the costs of small nuclear projects typically range from £100 million to £2.5 billion. Small nuclear projects can benefit from lower capital costs and quicker build times through modular construction and factory build (as opposed to on-site build) and are generally less complex than a GW nuclear project. These factors render a number of the risks more manageable, and the lower costs involved make the investment required for a small nuclear project within the range of a greater number of market participants (compared to larger projects).

Although the EFWG report focuses on small-scale nuclear new build projects, a number of the considerations and proposals may also be relevant for conventional large-scale nuclear power projects.
