Explanation / Answer

Fission of one kg of Uranium-235 generates about 8.31400 X 10^13 Joules of energy. Even if we assume that amount of fuel used in this case is only one gram, still we have 8.314 X 10^10 Joules of staggering energy that needs to be disposed off quickly and efficiently. Energy can not be destroyed, nor can it be generated, remember? So unless we have a system in place to utilise such amount of heat, we are going to get roasted. And I mean literally.

32 gallons can accommodate at most 121 litres of water. Let us assume that water is at room temprature, say at 20C. Now considering extreme case of boiling water at 100C, water will absorb Q=(100-20)*1000*1*121=9680 kcal of energy. This is about 4.05 X10^7 Joules of energy.

There is still 8.3099 X10^10 Joules of energy that is itching to be spent. Not only will this one gram of U-235 be sufficient to boil the water instantly, there will be enough energy still spared. Your guess is as good as mine as to what this energy will do to your overall health.
