the anti-nuclear movement grew in california between 1964 and 1974. it was during this period that some scientists and engineers began supporting the positions of the activists. they were influenced by the non-material philosophy that had inspired activists and had impacted the public consciousness. while californian voters failed to pass a 1972 proposal placing a 5-year moratorium on nuclear plant construction, anti-nuclear groups campaigned to stop construction of several proposed plants in the seventies, especially those located on the coast and near fault lines. these proposals included the sundesert nuclear power plant, which was never built.
