making the risks of a major release of radioactivity low.
The first is probably true. The second is blatantly false.
The terrorist do not need to breach the Containment Building to cause a major release.
Another thing in the article I have to question is the part about the 1 billion dollars the government has spent to boost nuke plant security. The government simply says the utilities has to meet this new standard and the Utilities have to come up with the money to pay for the improvements or loose their license to operate.
Nuke plants are probably the worst (from a terrorist point of view) target in the country.
But, people have been so propagandized by the media, fiction ("24" doesn't help), envirowhackos it's basically hopeless to convince anyone otherwise.
