Safer Nuclear Reactor Designs Are A Must

Posted by pwl on March 17, 2011

“Video of helicopters water-bombing nuclear reactor, close-up shots of Fukushima”

RT reports that allegedly only four helicopter loads of water have so far been dropped, and that 100 loads of water are needed to even have any cooling effect. Not good.

“17 March: During the morning, Self-Defense Force helicopters dropped four containers of water on the spent fuel pools of Units 3 and 4.[35] In the afternoon it was reported that the Unit 4 spent fuel pool is full with water and none of the fuel rods are exposed.[36] Construction work was started to supply a working external electrical power source to all six units of Fukushima I.[37]”
Fukushima I Nuclear Accidents, Wikipedia

When the last resort is dropping water onto nuclear rectors from helicopters is the solution being used you know it’s really bad. It looks like most of the water spray misses the target (hard to tell from the camera angle).

Clearly nuclear reactor designs must be revisited to take into account a complete loss of the coolant systems. Safer designs are a must, and designs that don’t have the flaws seen at Fukushima are a must.

Some immediately obvious design improvements.
