Not like Tesla has any guide for First Responders to help in said training efforts. Oh wait, they do. https://www.tesla.com/firstres...

Yes, but the problem at Fukushima is the residual heat from the still decaying by-products of the primary reaction (think Strontium, Cesium, Iodine) that continue produce heat. This will always happen and continuing to run the primary coolant through the stopped reactor is the only way to keep it safe until those by-products finish, usually weeks after the reactor has been stopped. If you want to know more about what happened at Fukushima, (http://bit.ly/h9Mwz0) is a layman's guide.

The newer Generation III+ reactors have solved most of the issues with this older design. Things like ensuring that the primary coolant loop will be gravity run in the event of failure, storing the extra coolant above the containment unit instead of below, etc. As long as the laws of physics still apply, we should be good.

Nuclear power has one of the top safety records (compared to other heavy industries and fossil fuel generation) but the whenever a disasters occurs, the public fail to focus on how the failsafes worked, or how the engineers did the right thing. The misinformation spread around by the fear mongers is the biggest danger to the public since power companies have been unable to build newer, safer reactors since the 70's. Power demands haven't gotten lower; they've increased and the demands we have put on the government to ensure lower carbon emissions and reduce pollution is going to make it difficult to continue with the more traditional fossil fuel based generators. None of the renewable methods (solar, wind, tidal, and geothermal) are ready for prime time and simply cannot take over for our power needs.
