A bare-spherical reactor 50 cm in radius is composed of a homogeneous mixture of 235 U and beryllium. The reactor operates at a power level of 50 thermal kilowatts. Using modified one-group theory, compute: (a) the critical mass of 235U; (b) the thermal flux throughout the reactor; (c) the leakage of neutrons from the reactor; (d) the rate of consumption of 235U.

4) Induction Effect. A very long solenoid of radius R-2.5 cm has n 5 turns/cm. Starting from an initial current of io 50 A at 1 = 0, a steadily increasing current is driven through the coils of the solenoid, at a rate of didt = 10 A/s. The solenoid is surrounded by a square flat "pickup" coil of N= 100 turns and of side lengthに10 cm (oriented with its plane perpendicular to, and its center at, the solenoid axis)....
