We do not need nuclear power.

Welcome to the Clamshell Alliance website. The Clamshell opposes nuclear power, a false solution to the climate emergency. The New England-based Clamshell Alliance inspired the national anti-nuclear movement in the 1970s. The Clamshell experience, which drew on the wisdom of generations of struggles, speaks to the world’s current crises. We persist in saying “No Nukes” as we all continue to strive for justice, joyfully, on many fronts.

PRAIRIE DOG ALLIANCE OF KANSAS
RESISTS UNTESTED AND DANGEROUS NUCLEAR POWER EXPERIMENT

On December 4, 2025, residents of Parsons Kansas woke to a nasty surprise. A nuclear startup company, Deep Fission, was briskly moving to install experimental nuclear micro reactors a mile underground in their town. The dubious nuclear power project is to have six interconnected 15-MW reactors with no radiation shielding. Deep Fission is shooting for a July 4, 2026 reactor criticality. 

Then up popped the Prairie Dog Alliance (PDA), a group of local residents with an increasing number of allies. PDA’s Marjorie Reynolds says, “Many in our community were not given a vote or a voice in this decision, and we believe it is crucial to inform and educate the public about the potential risks and impacts of this project.”
Clamshell Alliance and many others are supporting PDA. Donations to support Prairie Dog Alliance can be sent here. For more information on PDA and Deep Fission, from various sources, read the details here.
