Local Activists for a Nuclear-Free Future
Legal Intervenors in Diablo Safety Issues since 1973
San Luis Obispo Mothers for Peace is a non-profit organization concerned with the dangers posed by Diablo Canyon and other nuclear reactors, nuclear weapons, and radioactive waste. Additionally, the organization works to promote peace, environmental and social justice, and renewable energy.
Radioactive Waste
Safe storage of high level radioactive waste is the Achilles’ heel of the nuclear industry. The waste must be stored and isolated from the environment for a million years.
After decades of failed policy, there exists no environmentally safe, just, and equitable solution to the storage of high level radioactive waste.
DECOMMISSIONING
Although Diablo Canyon nuclear plant shuts down in a few years, there still exists the issues of decommissioning and the safe storage of its waste.
The Diablo Canyon nuclear reactors are scheduled for closure in November 2024 for Unit 1 and August 2025 for Unit 2.
Climate and Energy
San Luis Obispo Mothers for Peace (MFP) recognizes the threat to all life forms on the planet posed by the increase in carbon dioxide. Human activities, especially since the industrial revolution, have caused this climate change. MFP works in conjunction with like-minded organizations to preserve a livable world for future generations.
