Explain and show how to solve for ONLY part E and F from the provided solution since they don't plug in all the numbers to solve and doesn't provide an answer for part e. Provided is the solution of all the previous parts so that the other solutions would be carried over to the next parts. DO NOT USE AI SINCE THEY'RE WRONG

6.28) The core of a spherical reactor consist of a homogeneous mixture of "U and graphite with a fuel- moderator atom ratio NF/NM=6.8x10". The core is surrounded by an infinite graphite reflector. The reactor operates at a thermal power of 100kW. Calculate the: (a) value of koo: (b) critical core radius; (c) critical mass; (d) reflector savings; (e) thermal flux throughout the reactor; (f) maximum to average flux ratio. Solution: (a) 1 =0.573 and 1 = 2.065 1+ NMC all NFO OF where NF/NM=6.8x10* and aF = 687band aM = 0.0034b => k = fn=1.183 for &= p=1 (b) BRCot(BR) -1= - D, (R + 1) = BCot(BR) =- 1 where D, = D. D.
