Nuclear Terrorism: Fear vs. Reality - The New American

Fukushima ProofThe Real DangerA Better SolutionFukushima provides a real-life example of the hardiness of nuclear reactors. Tokyo Electric Power Company’s Daiichi plant was crippled by something exponentially more destructive than a fuel-laden jet: the 9.0 magnitude earthquake and devastating tsunami that hit in March 2011. Despite a storm that claimed nearly 20,000 Japanese lives, despite the fact that the earthquake was of far greater magnitude than the plant was rated to withstand, and despite the loss of all power including backup generators, the inner containment structures remained intact, and all nuclear chain reactions came to an immediate halt. Some exterior containment buildings did sustain damage. Their story provides insights into the possible consequence of a terrorist attack. The exterior structures are designed to protect the plant from Mother Nature, and they too lived up to their calling despite her violence that day. However, the handicapped cooling system couldn’t maintain a water level above the tops of spent...Get price
