The backer of a ballot initiative to shut down California\u2019s nuclear plants filed with the state Attorney General Sept. 28 for an official title and summary. The proposed measure was approved for signature collection by the state May 23. \u201cMy plan for signatures is focused on getting an honest and fair fiscal analysis,\u201d noted sponsor Ben Davis Jr. He said that process could begin this week. \u201cIf I fail at getting such an analysis, whether I go ahead with the petition drive is questionable as it will be hard to get grass-roots support,\u201d he added. In order to get to the ballot, the initiative requires 504,760 signatures. The initial analysis by the Legislative Analyst\u2019s Office, reported that passing the measure could cost the state $4 billion and lead to blackouts. The California Independent System Operator said that if the ballot measure passes, grid reliability would be a factor. Davis and other environmentalists claim that the financial risk of keeping nuclear plants running with potential accidents and radioactive releases is the true cost. \u201cIn balancing the benefits and risks associated with energy production, nuclear fission is the least desirable means of producing electrical energy available in the State of California,\u201d reads the initiative. For instance, Japan\u2019s government announced that it found highly radioactive bits of plutonium far away from the containment building Oct. 1--seven months after the Fukushima Daiichi explosions and meltdowns. Davis doesn\u2019t expect the initiative to be cleared by the Secretary of State before the end of the year. The federal Nuclear Regulatory Commission maintains California\u2019s nuclear facilities can be run safely, although it recognizes the potential for earthquakes to influence the plants. In the wake of the Fukushima Daiichi meltdowns, the commission and staff have held a series of meetings to find how to apply \u201clessons\u201d learned from the meltdowns in Japan. The commission plans investigations, called \u201cwalk downs\u201d for California and other earthquake-prone nuclear plants. A walk down \u201cmeans NRC inspectors physically \u2018walk down\u2019 every piece of piping in the system\u201d to attest to its integrity, according to the commission.
