Even when shut down after a period of normal use, a large commercial nuclear reactor produces heat at the rate of 147 MW by the radioactive decay of fission products. This causes a rapid increase in temperature if the cooling system fails.
Calculate the rate of temperature increase in degrees Celsius per second (° C/s), if the mass of the reactor core is 1.60 x 10⁵ kg and has an average specific heat of 0.0800 kcal/(kg ·° C).
