Problem 4: Even when shut down after a period of normal use, a large commercial nuclear reactor transfers thermal energy at the rate of 150 MW bythe radioactive decay of fission products. This heat transfer will cause a rapid increase in temperature if the cooling system fails.Part (a) Calculate the rate of temperature increase, in degrees Celsius per second (°C/s), if the mass of the reactor core is 1.85 x 10° kg and it hasan average specific heat of 0.3349 kJ/(kg.°C).AT'At =sin()cos()tan()79HOMEcotan()asin()acos()E45atan()acotan()sinh()13cosh()tanh()cotanh()END-ODegrees O RadiansBACKSPACE DEL CLEARSubmitHintFeedbackI give up!Part (b) How long, in minutes, would it take for the temperature to increase by 2000°C, which could cause some metals holding the radioactivematerials to melt? (The initial rate of temperature increase would be greater than that calculated here because the heat transfer is concentrated in a smaller mass.Later, however, the temperature increase would slow down because the 5 x 102-kg steel containment vessel would also begin to heat up.)

If you lie on the ground at night with no cover, you get cold rather quickly. Much of this is due to energy loss by radiation. At night in a dry climate, the temperature of the sky can drop to -40◦F. If you are lying on the ground with thin clothing that provides little insulation, the surface temperature of your skin and clothes will be about 86 ◦F. Estimate the net rate at which your body loses energy by radiation to the night sky under these conditions.
