Problem 55.3 (RHK)

We have to answer the following:

(a) How many atoms are contained in 1.00 kg of pure ? (b) How much energy, in joules, is produced by the complete fissioning of 1.00 kg of ? We may assume . (c) For how many years would this energy light a 100-W lamp?

(a)

The number of atoms in 1.00 kg of pure will be

(b)

It is given that energy released by fission per nucleus is 200 MeV. Therefore, the total energy, in joules, produced by complete fissioning of 1.00 kg of pure , or atoms, will be

(c)

The total time for which a light bulb of 100 W will glow with this energy will be
