Verify that, as reported in Table 43-1, fissioning of the 235U in 1.0 kg of UO2 (enriched so that 235U is 3.0% of the total uranium) could keep a 100 W lamp burning for 690 y.
In a particular fission event in which 235U is fissioned by slow neutrons, no neutron is emitted and one of the primary fission fragments is 83Ge. (a) What is the other fragment? The disintegration energy is Q = 170 MeV. How much of this energy goes to (b) the 83Ge fragment and (c) the other fragment? Just after the fission, what is the speed of (d) the 83Ge fragment and (e) the other fragment?
A standard nuclear power plant generates 3.0 GWGW of thermal power from the fission of 235U235U. Experiments show that, on average, 0.19 uu of mass is lost in each fission of a 235U235U nucleus.
How many kilograms of 235U235U undergo fission each year in this power plant?
Express your answer in kilograms per year.
