[Decarburization] An FCC iron-carbon alloy initially containing carbon with the concentration, C0, is exposed to anoxygen-rich and virtually carbon-free atmosphere. Under the given conditions, the carbon diffuses from the alloy andreacts at the surface with the oxygen in the atmosphere, meaning that the carbon concentration at the surface position is maintained essentially at 0 wt% C. The subproblems are independent.(1) Determine the diffusion coefficient at the temperature T given below. Use T = 1250 °C(2) When the value of D is given below, what position will the carbon concentration be Cx after a treatment for thetime, t? Use D = 1.93 × 10−10m2 /s; C0 = 0.35 wt%; Cx = 0.11 wt%; t = 12 hr

Problem 3. Phosphorus is diffused into a thick slice of silicon with no previous phosphorus in it at a temperature of 1100°C. If the surface concentration of the phosphorus is 1 x 10 atoms/cm and its concentration at 1 µm is 1 x 105 atoms/cm, how long must be the diffusion time? D = 3.0 x 10 cm?/s for P diffusing in Si at 1100°C.

(a) Assume that in each fission of 235U, 200 MeV is released. Assuming that 5% of the energy is wasted in neutrinos, calculate the amount of 235 U burned which would be necessary to supply at 30% efficiency, the whole annual electricity consumption in Britain 50 × 10⁹ kWh (b) A thermal reactor contains 100 tons of natural uranium (density 19) and operates at a power of 100 MW (heat). Assuming that the thermal cross- section of 235 U is 550 barns and that the uranium contains 0.7 % of 235 U. Calculate the neutron flux near the centre of the reactor by neglecting neu- tron losses from the outside, and assuming flux constant through out the lattice. [University of Liverpool 1959]
