San Luis Obispo Mothers for Peace



Mission: 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.

Mothers for Peace uses a variety of strategies to achieve these goals:

  • Monitors proceedings before the Nuclear Regulatory Commission, the California Public Utilities Commission, and other government agencies;
  • Educates the public via social media, speaking events, rallies, mailings, letter-writing campaigns, letters to editors and opinion pieces in newspapers;
  • Commemorates important historical events related to our goals;
  • Provides scholarships for local high school and college students whose goals and actions exemplify our mission.    

Origins: The San Luis Obispo Mothers for Peace was organized in 1969. A young mother wrote a letter to the editor of the local newspaper asking that people who shared her sadness and frustration at the needless loss of life in the Vietnam War join her in speaking out. The shared values and compelling need to act effectively as a group have continued to characterize the Mothers for Peace.

Members: The group is a local, non-profit organization (501c3). Its members include mothers, grandmothers, and non-parents. Its membership is predominantly, but not exclusively, women.

Legal Intervention: Since 1973, the Mothers for Peace has focused much of its attention on the local dangers posed by operation of the Diablo Canyon Nuclear Power Plant. MFP has been the legal intervenor of the Diablo Canyon facility for over four decades of controversies concerning the construction, licensing, operation, and storage and disposition of the radioactive waste. 

MFP utilizes all legal means to ensure, to the extent possible, the safe operation of the plant and its compliance with State and Federal Laws.  See the Path of Legal Resistance.

Specifically, Mothers for Peace has been involved in litigation and public hearings involving the following issues: initial and subsequent licenses, seismic safety, County Emergency Response Plan, high level radioactive waste storage and transport risks, rate structure and deregulation, degradation of coastal waters, plant security, and now decommissioning plans.
