A large power reactor that has been in operation for some months is turned off, but residual activity in the core still produces 135 MW of power.
If the average energy per decay of the fission products is 1.04 MeV, what is the core activity in units of curies?
One idea of fuelling an internal confinement
fusion reactor is to use deuterium-tritium (D-
T) pellets. Calculate how many 1 mg pellets of
D-T material per second would be required
for a 500 MVW reactor if 30 % of the material
in each pellet were converted in internal
confinement fusion.
How many neutrons per second are emitted spontaneously from a 1 mgsample of 252Cf? For 252Cf assume the following data:T1/2 = 2.745 y γn = 0.0309 (that is, fraction of decays that are spontaneous fission)ν = 3.73 (average number of neutrons created per spontaneous fission)

This result is about 6 MeV greater than the result for spontaneous fission. Why? Confirm that the total number of nucleons and total charge are conserved in this reaction.arrow_forwardIn a nuclear power generating plant, heat from a reactor is used to generate steam for turbines. The rate of the fission reaction determines the amount of heat generated, and this rate is controlled by rods inserted into the radioactive core. The rods regulate the flow of neutrons. If the rods are lowered into the core, the rate of fission will diminish; if the rods are raised, the fission rate will increase. By automatically controlling the position of the rods, the amount of heat generated by the reactor can be regulated. Draw a functional block diagram for the nuclear reactor control system shown in the figure below. Show all blocks and signals.arrow_forward
