Pronuclear Advocates & Allies

Pronuclear advocacy has been growing worldwide. The number of groups working to save existing nuclear, reform clean energy policies to be “nuclear-inclusive,” and to educate the public about the benefits of nuclear is expanding at a rapid clip. That’s the good news and a reflection of growing public support for the use of nuclear power as a solution to climate change. The bad news is that there are very few groups that are either large or mainstream.

The movement is in a grassroots stage with lots of independent actors deciding to organize, at times without even realizing that other similar groups exist. Fortunately, many of these groups are connected through overlapping membership, so there is suprisingly effective coordination when it matters, such as when it comes to saving existing power plants. This coordination started with the Climate Coalition campaign to save New York’s Indian Point, which did not succeed. But the groups involved saw the power of cross-coordination and learned from that experience. They have since become increasingly successful at orchestrating multi-facted campaigns to save at risk power plants. The fact that the Biden Administration is actively providing financial support for at risk plants which eases the burden on ratepayers has also helped a lot.

Many of those who contact us want to know how they can help nuclear power succeed in addition to or in lieu of investing in next-generation technologies through Nucleation Capital. None of the main environmental groups (Sierra Club, NRDC,, Friends of the Earth, League of Conservation Voters, Greenpeace, etc.) have had the courage and integrity to come out in public support of nuclear. Even though a few of the more scientific groups (The Nature Conservancy, The Union of Concerned Scientists, World Resources Institute) have opted to take a more neutral or nuanced stance vis-a-vis nuclear, we don’t recommend giving your philanthropic dollars to any of these larger groups until they support nuclear power. Thus, we have curated this list of the most effective pronuclear non-profits and advocates to help you find an organization or individuals to support.

Nucleation’s Top 5 Pronuclear Organizations


Californians for Green Nuclear Power, led by Dr. Gene Nelson, has  been a driving force for political accountability and responsible energy decision-making in California. Shedding light on sweetheart backroom political deals being cut by Governor Jerry Brown that were contrary to the public interest, CGNP filed suits and/or petitioned to become a party to CPUC and FERC proceedings. CGNP’s work as an intervenor has been instrumental in helping to save Diablo Canyon. CGNP’s in depth research continues to pose obstacles to efforts to overturn the California legislature’s extension approval are being filed. (Donations can be mailed to CGNP at 1375 East Grand Ave Ste 103 #523, Arroyo Grande, CA 93420-2421.)


Mothers for Nuclear was created on Earth Day 2016 by the power team of San Luis Obispo-based Heather Hoff and Kristin Zaitz, two moms to better represent the voices of women and mothers in support of Diablo Canyon and nuclear energy in general. Coordination with Californians for Green Nuclear Power, Save Clean Energy and many other groups enabled Governor Newsom to respond to strong public pressure to save Diablo Canyon when appealing to the California Legislature. Progressive women remain predominantly opposed to nuclear power, but Mothers for Nuclear have begun to rebuild the social norm of women being pronuclear. (Donations can be made online. EIN: 81-3349003)


Generation Atomic was created by Millenial Eric Meyers to represent the voices of younger generations and empower them to express support for nuclear in every type of venue and forum where discussions of how solve climate change is happening. The group creates fun, engaging, public actions in an effort to safeguard our future by championing the cause for nuclear energy. Not only do they use research, communication and relationship-building to advocate for nuclear, their actions typically involve dancing, singing, inflatable costumes and a high degree of humor to inspire, empower and engage youth and keep those who are anti-nuclear or who just wish to ignore the issue off-balance. Operatic nuclear arias, anyone? (Donations can be made online. EIN: 81-4500446)


Thorium Energy Alliance was started in 2006 by John Kutsch to bring together scientists and energy experts who believe that thorium should be used as nuclear fuel. Thorium is far more abundant and less radioactive than uranium, yet was rejected early on in the history of nuclear development, despite evidence that thorium could power a molten salt reactor safely and be highly cost-effective. TEA has worked to protect nuclear’s abundant innovation history as well as raise awareness about abundant but wasted materials like thorium. TEA has served as a central organizing entity, advocating for alternative reactor designs within broader discussions of how to expand access to nuclear power. John Kutsch has provided guidance, support and inspiration for many young activists, which history was beautifully captured in the Frankie Fenton documentary film “Atomic Hope.” (Donations of cash or cars can be made online.)


RePlanet was founded by a group of European youths to broadly save the future. They bravely tackle a number of big thorny issues, including the need to rethink and deploy advanced technologies for food production, nuclear power and GMOs. In particular, they recently launched a campaign called “Dear Greenpeace” initiated by Ia Aanstoot, a Swedish teen, which seeks to get one of the largest and most militant of environmental NGOs to focus on fighting fossil fuels, not nuclear power. Ironically, the so called “environmental” groups are some of the most ignorant about how best to solve climate change. They are ideologically-driven and persist in opposing nuclear power, thereby enabling the continued use of fossil fuels. Because of how energizing and refreshing this campaign is, we recommend supporting RePlanet, which is willing to publicly call out the environmentally detrimental actions of a mainstream “green” NGO. (Donations can be made online.)
