A member of Mothers for Peace, the organization which brought a lawsuit against the Diablo Canyon Nuclear Power Plant, delivers an unsolicited address from the floor of the Nuclear Regulatory Commission Licensing Board hearing in San Luis Obispo in Summer 1981. Contains sensitive language. Tape label: "According to Mothers for Peace, the legal intervenors in the Diablo Canyon case, local opposition to the plant has sky-rocketed over the last 2 months, as the licensing date drew near and as the people of San Luis began to realize that Federal authorities were not going to keep the plant from opening. For many San Luis residents, that realization came during the most recent set of license hearings held in their town.".
