(a) – (d) Complete the following table, which refers to the generalized fission reaction
Verify that, as stated in Module 43-1, neutrons in equilibrium with matter at room temperature, 300 K, have an average kinetic energy of about 0.04 eV.
In an atomic bomb, energy release is due to the uncontrolled fission of plutonium (or ). The bomb’s rating is the magnitude of the released energy, specified in terms of the mass of TNT required to produce the same energy release. One megaton of TNT releases of energy. (a) Calculate the rating, in tons of TNT, of an atomic bomb containing 95 kg of , of which 2.5 kg actually undergoes fission. (See Problem 4.) (b) Why is the other 92.5 kg of needed if it does not fission?
The uranium ore mined today contains only 0.72% of fissionable , too little to make reactor fuel for thermal-neutron fission. For this reason, the mined ore must be enriched with . Both role="math" localid="1661753958684" and are radioactive. How far back in time would natural uranium ore have been a practical reactor fuel, with a ratio of 3.0%?
