The conclusion is worth stating:
How safe is safe enough? Throughout the history of nuclear power, utilities and regulators have assured the public that their plants can withstand every emergency situation except the truly unimaginable. But the unimaginable can happen, as it did on the coast of Japan on March 11, 2011.
“Fukushima” shows in sobering detail what can follow when those with a vested interest in making the technology seem safer than it is decide not to plan for an extreme event because “it can’t happen here.” The authors remind us: Yes, it can. “
” On March 18, 2011, an official from theU.S. Nuclear Regulatory Commission named Chuck Casto called together the NRC delegation on assignment with him in Tokyo.
“We’re in never-never land,” he told them.
Seven days earlier, a magnitude 9 earthquake had rattled a complex of six nuclear power plants known as Fukushima Daiichi, roughly 150 miles northeast of Tokyo. Then came nature’s second, more devastating blow: a tsunami that swamped the complex, flooding its electrical generators and putting its three operating reactors out of commission. The reactors were soon out of control, the plant effectively disabled by that most feared event in the nuclear industry: a “station blackout,” when no power is available to run any of the safety systems designed to defend the public from a runaway reaction.
In the days that followed, three explosions blew apart portions of two reactor buildings, and the reactors’ fuel cores at least partly melted…
