QUESTION 1 a Consider radioactive wastes (krw = 20 W/m-K) being stored in a cylindrical , stainless steel (kss - 15 W/m-K) container of inner and outer radii equal to n = 0.1 m and ro= 0.12 m, and the length is 5 m. Heat is generated volumetrically within the wastes at a uniform rate of 10 W/m', and the outer surface of the container is immersed in water at 25°C and the convection heat transfer coefficient h = 100 W/m2-K. Steel container Radioactive wastes (a) a You, as a new engineer of the company, are tasked to evaluate the container of radioactive wastes. What is the rate of heat generated by the radioactive wastes in the container per unit length? (3 marks) (i) (ii) Draw a thermal circuit to represent heat loss from the radioactive wastes. Clearly label the temperatures and the thermal resistances (using appropriate equations and the dimensions/parameters of the container) in the thermal circuit. (4 marks) (iii) Calculate the temperature of the core of the radioactive wastes. (10 marks)
