To state:

if in a nuclear power reactor with k = 1, control rods are used to reduce the power output of the reactor to 25% of its original value; will k be less than, equal to or greater than 1.

A nuclear reactor is operating at a certain power level, with its multiplication factor k adjusted to unity. If the control rods are used to reduce the power output of the reactor to 25% of its former value, is the multiplication factor now a little less than unity, substantially less than unity, or still equal to unity?
How many kilograms m of uranium-235 must completely fission spontaneously into (140)Xe, (92)Sr, and three neutrons to produce 1200 MW of power continuously for one year, assuming the fission reactions are 26% efficient? m = ? kg
A reactor operates at 400 MW with a neutron generation time of 30.0 ms. If its power increases for 5.00 min with a multiplication factor of 1.0003, what is the power output at the end of the 5.00 min?
