Here's an LA Times photo from March 15, 1965. Published caption: "REACTOR SITE-Three members of the Atomic Energy Commission Safety and Licensing Board inspect site of proposed nuclear reactor power plant in Coral Canyon, Malibu. They are, from left, Dr. Lawrence Quarles, Hood Worthington and Samuel Jensch. They are holding hearing in Santa Monica this week."
The general plan for Malibu, drafted in 1960, called for a freeway down Malibu Canyon Road (to connect with another freeway that ran over the ocean), Marina del Rey-density development, and this nuclear reactor. (UCLA archive)
