Who are the

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:

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

Origins: The San Luis Obispo Mothers for Peace came together in 1969. A young mother had written 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 searching out ways to act effectively as a group. The shared values and compelling need to act that originally brought the group together 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 involving Diablo Canyon Nuclear Power Plant. It has been the legal intervenor for over four decades of controversy concerning the construction, licensing, and operation of the Diablo Canyon facility.

The organization utilizes all legal means to ensure safe operation and 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, rate structure and deregulation, degradation of coastal waters, plant security.
