In a decision supporting environmentalists\u2019 concerns about the Diablo Canyon nuclear power plant, the California Public Utilities Commission approved up to $16.73 million to study the earthquake faults near the facility. The investigation is set to use new three-dimensional technology to evaluate potential effects of a temblor on the facility. \tThe August 12 decision gave Diablo\u2019s owner, Pacific Gas & Electric, authority to spend the funds, but it also requires the utility to set up a \u201cpeer review\u201d panel to assure independence in how the study is conducted and how the findings are presented. \tIt\u2019s been known since Diablo\u2019s construction that the reactors sit less than three miles from the Hosgri fault. Another, more recently discovered fault, the Shoreline, is even closer to the facility. \tEnvironmentalists fear that an earthquake could tear apart Diablo Canyon\u2019s radioactive parts, releasing cancer-causing materials into the environment. Environmentalists, like Mothers for Peace in San Luis Obispo, believe that more scientific studies will keep the nuclear power plant from receiving an extended license to keep it in production until about 2045.
