In the 1980’s the U.S. Court of Appeals ruled 5-4 that there was no reason to require nuclear plants to create earthquake disaster plans.

In 2003, an earthquake in California, prompted the Diablo Canyon plant officials to come up with a plan.  But, for some unknown reason, they have yet to publish that plan. The plant operators were not required to include earthquakes in its emergency response plan, when the plant was first licensed.

In fact according to the Nuclear Regulatory Commission, nuclear plants in the U.S. are required to have only a general emergency response plan.  In other words they don’t plan for specific types of disasters.

Some officials say no planning is needed because the plants were supposedly built to withstand earthquakes.  Tell that to the Japanese.  Two workers at the Fukushima Daiichi plant, who survived the 9.0 quake/tsunami, say the plant was falling apart.  One of those workers said he was surprised because everyone had been told the plant was earthquake proof.
