Help Protect Our Coast

Help us oppose the Coastal Commission’s approval of Southern California Edison’s plan to demolish San Onofre spent fuel pools.

Spent fuel pools could be used to contain radiation in an emergency and provide a safe location to repair or replace damaged storage canisters.

Open Letter to California Leaders: Where is the Action on Nuclear Waste?

We stand for the secure containment of radioactive material to ensure the protection of our environment, economy and way of life.
