For example , if a nuclear fission reactor produces an
average power of 1.0 GW
over the year (10^9 W), what mass of U-235 has undergone
fission in that time? Use the stat that on average 200 MeV energy
is
released per fission reaction.
Please not that on average a mole of uranium (containing 6.023 ×
1023 nuclei) has a
mass of 235.043930 g

If a nuclear fission reactor produces an average power of 1.0 GW over the course of a year, what mass of U-235 has undergone fission in a 365-day year? Assume on average 200 MeV energy is released per fission reaction. Hint: One mole of uranium (containing 6.023 x 1023 nuclei) has a mass of 235.043930 g.

Nuclear power plants convert the energy released in fission reactions to electric energy. Consider one such power plant that generates 1.00 GW of electric power. The fission of each uranium-235 nucleus releases 200 MeV of energy. The power released by the fission reactions is converted to electric power with a 41.0% efficiency. How much uranium-235 per day, by mass in kg, undergoes fission at this power plant?
If the required power output of a nuclear plant that has an overall efficiency of 37.3% is 1.05 Gw, determine the amount of nuclear fuel (in kg) consumed each day if the fuel is 222U and each fission...

Burning 20 tons of coal provides about 5. 1011 J, which is approximately the annual energy requirement of an average person in the United States. If this amount of energy was provided by the electricity generated by the fission of uranium-235 in a nuclear reactor, instead, what mass of natural uranium would be required? About 0.7% of natural uranium is uranium-235 (almost all the rest is uranium-238, which does not fission like U-235 does). Assume that the fission of each...

EXAMPLE 8.11 MODERATING FISSION NEUTRONS IN A NUCLEAR REACTOR LUTION The fission of uranium nuclei in a nuclear reactor produces high- speed neutrons. Before such neutrons can efficiently cause addi- tional fissions, they must be slowed down by collisions with nuclei in the moderator of the reactor. The first nuclear reactor (built in 1942 at the University of Chicago) used carbon (graphite) as the moderator. Suppose a neutron (mass 1.0 u) traveling at 26...
