In a reactor 2 kg of uranium fuel is fully
WebNov 1, 2024 · The complex included five reactors to produce these radioactive materials and two separations facilities to isolate and purify them. SRS produced the Pu-239 from a combination of uranium-235 (U-235) and U-238 in the reactors. U-235 in this “fuel” released neutrons that struck U-238, converting some of it into U-239. WebProblem: A reactor is fueled with 4 kg uranium enriched to 20 atom-percent in 235U. The remainder of the fuel is 238U. The fuel has a mass density of 19.2 g/cm3. (a) What is the mass of 235U in the reactor? (b) What are the atom densities of 235U and 238U in the fuel? Solution: The atom density may be found utilizing Eq. (1.5) as follows:
