Progress Towards Nuclear Energy

Welcome! We are pleased to share various resources which we are using to track the progress of growth of nuclear energy usage globally.  We endeavor to add notable events both in the industry and within the climate community to the above timeline. Additionally, we present two tables:  1. US States’ Movement towards Nuclear, which activity falls primarily into five buckets ranging from repealing older nuclear energy bans to passage of laws to allow SMRs (see color coding); and    2. International Movement towards Nuclear, which tracks activity by other countries to restart reactors, expand existing capacity or add new nuclear capacity.

1.  U.S. States’ Movement towards Nuclear

We are pleased to provide this state-by-state listing of the legislation being proposed and passed across five main categories since 2016. These include: Zero-Emission Credit programs to protect viability of existing plants; Repeals of nuclear bans on construction of new nuclear; Funding of Feasibility Studies for deployment of new nuclear; and support for deployment of Advanced nuclear and SMRs or support for Fusion nuclear. Click on the state name to toggle open the information. Once open, you can scan the entries by the following categories:











  • A.B. 65 (Introduced Dec. 6, 2022)

    Legislation introduced by Devon Mathis, Rep. from the 33rd District to eliminate the prohibition against building new nuclear powerplants, in the absence of a permanent solution for storage of spent fuel rod assemblies.

  • S.B. 846 (Passed August 31, 2022)

    Legislation proposed by Governor Newsom and sponsored by Jordan Cunningham to save Diablo Canyon from premature closure. This legislation was passed almost unanimously by both the predominantly Democratic California Assemby and the predominantly Democratic Senate (Votes in favor: 98; votes opposed: 4). It specifically enables PG&E to receive up to $1.4 billion as a loan from the state to support continuation of the Diablo Canyon Nuclear Power Plant, including its reapplication with the NRC. The timing allows the plant to apply for the DOE’s Civil Nuclear Credit program. This legislation would keep Diablo’s Unit 1 open until October 31, 2029, and Unit 2 until October 31, 2030, with annual reports on the PUC’s resource plans. After five years, the state would assess whether the units should stay open for another five years, with a final expiration set for October 31, 2035.

2.  International Movement towards Nuclear

(Click to see full PDF)

The U.S. is the world’s top producer of nuclear power, with 92GWs of generating capacity, comprising more than 30% of the total global nuclear energy production, and representing 20% of U.S. total electricity consumption.  France is the number two producer, with over 61GW of capacity, which generates almost 70% of its electricity demand, some of which is exported to other countries. China has 51GW, enough to cover about 5% of its electricity but it is rapidly building new capacity, with 18 additional reactors under construction and many more in planning.  Meanwhile, Japan (32GW), Russia (30GW), South Korea (25GW), Canada (14GW), Ukraine (13GW), the UK (9GW) and Spain (7GW) make up the top ten nuclear countries, as of 2021.  To learn more about the status of nuclear power usage internationally, please see the International Atomic Energy Agency’s (IAEA) Country Nuclear Power Profiles.  Click on the image to the right, to enlarge the IAEA’s 2021 Nuclear Power Status infographic.

The combination of pressure to decarbonize and growing uncertainty of international supplies as a result of Russia’s invasion of Ukraine, has many more countries exploring nuclear energy. We are tracking news about efforts to increase nuclear energy within other countries, both the thirty countries which are already using nuclear to some degree and another thirty “newcomer” countries which are actively working to adopt nuclear energy. We present this news within a groupable, sortable, searchable airtable. You may change the grouping, filtering or sorting settings of the table by clicking the icons at the top.
