Fission of 235U occurs when the nucleus absorbs a single neutron and decays to smaller nuclei, liberating additional neutrons in the process. Each of these neutrons stimulates fission of other 235U nuclei in the next cycle of the chain reaction. If the average number of neutrons produced in each fission event is 1.9, how many cycles of the chain reaction are required to consume 2.3 kg of 235U?

. Suppose that neutrons are born with a kinetic energy 1 MeV from nuclear fission. Find the probability that a neutron will downscatter to a kinetic energy of 0.025 eV (after several collisions) with the following isotopes, having respective capture probabilities p(gamma) per collision: (a) A=1, Hydrogen with p(gamma)= 1×10−3, (b) A=2, Hydrogen with p(gamma)= 2×10−5, (c) A=12, Carbon with p(gamma)= 5×10−5, (d)A=23, Na with p(gamma)= 8×10−3. Use the results to discuss which of these isotopes are most effective at...

A 53 kiloton atomic bomb is fueled with pure 235U, 4.0% of which actually undergoes fission. (a) What is the mass of uranium in the bomb? (It is not 53 kilotons - that is the amount of released energy specified in terms of the mass of TNT required to produce the same amount of energy.) (b) How many primary fission fragments are produced? (c) How many neutrons generated in the fissions are released to the environment? (On average, each fission...

A beam of neutrons, 0.29 eV kinetic energy and 105 s−1 intensity, bombards a foil of 235U 0.1 kg/m^2 thickness. Calculate the number of fission reactions occurring per second in the foil, knowing that the fission cross section at the given neutron energy is 200 b. Need all computations for the final answer please.

Nuclear power comes from the conversion of mass to energy by the equation E=mc2. In nuclear reactions the energy released is found by taking the total of the mass of the reactants minus the total mass of the products and mulitplyig by c2. We are going to look at the enrgy produced by a typical fusion reaction and a typical fission reaction and compare that to the energy content of chemical reactions Fission is splitting an atom into two smaller...

The nuclear potential energy that binds protons and neutrons in a nucleus is often approximated by a square well. Imagine a proton confined in an infinitely high square well of length 10.3 fm, a typical nuclear diameter. Assuming the proton makes a transition from the n = 3 state to the ground state, calculate the following. (a) the energy of the emitted photon (b) the wavelength of the emitted photon (c) Identify the region of the electromagnetic spectrum to which...
