How many scatters with h and with 235U. on the average would it take for 2 Mev neutrons to reach an average thermal energy of0.025 eV? Discuss the relative merits of water and graphite for use in a thermal reactor Plot the thermal fission factor for uranium as a function ofits atom-% enrichment in 235U Consider a homogeneous mixture of fully enriched 235U and graphite. Plot Ko versus N235/Nc. What is the fuel-to-moderator ratio that yields the maximum value ofk?
How many scatters with 1H and with 235U, on the average, would it take for 2 Mev neutronsto reach an average thermal energy of 0.025 eV? Discuss the relative merits of water and graphite for use in a thermal reactor. Plot the thermal fission factor for uranium as a function of its atom-% enrichment in 235U. Consider a homogeneous mixture of fully enriched 235U and graphite. Plot k∞ versus N235 /Nc . What is the fuel-to-moderator ratio that yields the maximum value of k∞?
