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 or extended operation?
Diablo Canyon nuclear plant was scheduled to retire in 2024 and 2025 through a 2016 joint agreement between its owner, Pacific Gas and Electric Company (PG&E), labor, consumer advocacy and environmental groups. However, over the last year, there has been a push to extend operations beyond these shutdown dates based on Governor Newsom’s claim that its energy is needed.
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.
