Environmental Groups Demand Shutdown of Diablo Canyon Nuclear Power Plant

The Diablo Canyon Power Plant, California's last operating nuclear power plant, has come under intense scrutiny from environmental groups due to concerns over public safety and the risk of "nuclear meltdown." The groups, Friends of the Earth and Mothers for Peace, have filed a petition with the Nuclear Regulatory Commission, arguing that critical inspections on the Unit 1 reactor's pressure vessel have been delayed for nearly 20 years. The petition states that these delays pose grave public safety concerns, and the groups demand that the reactor be shut down until comprehensive testing and inspection are conducted.

Key Takeaways:

  • Environmental groups Friends of the Earth and Mothers for Peace have filed a petition with the Nuclear Regulatory Commission to shut down the Unit 1 reactor at Diablo Canyon due to delayed inspections and concerns over public safety.
  • The groups argue that the pressure vessel's structural integrity has been compromised due to embrittlement, a process that gradually weakens the reactor vessel due to neutron radiation.
  • The petition includes a 46-page report by University of California at Berkeley professor Digby Macdonald, which states that continued operation of the Unit 1 reactor "poses an unreasonable risk to public health and safety."
  • Pacific Gas and Electric (PG&E), the operator of the plant, claims to be in "full compliance" with regulatory standards and states that the Nuclear Regulatory Commission's current assessment places Diablo Canyon among the highest performing plants in the nation.
  • A California judge previously rejected a lawsuit by Friends of the Earth to prevent the plant from operating past its original 2025 deadline, but the organization has vowed to continue its legal battle.
