Worldwide standard operating procedures at nuclear power plants offer little margin for safety errors, and the industry is scrambling to check safety at each station. But can it reliably prevent another accident? Accidents are difficult to predict and have immediate far-reaching consequences, compounded by the fact that most nuclear reactors are located near major population centers – Moscow, Boston, Chicago, Los Angeles, Budapest, Kiev. It is nearly impossible to evacuate hundreds of thousands of people in a timely fashion, even with advance warning of several days – as hurricane Katrina demonstrated in New Orleans.
Officials at the Japanese nuclear plant did not think to have closed-circuit cameras inside the buildings to chart an accident for which they never fully planned. But we can be certain of the following. Officials belatedly warned surrounding residents of the danger to their lives, belatedly began to issue potassium iodide tablets to protect them, and belatedly expanded the evacuation zone around the station. Now at least 100,000 people have had to leave the area, and at least 100,000 more have been forced to live inside of sealed houses. At Chernobyl, as well, the authorities only ordered evacuation after a shocking delay.
