The author explores the relevant computational methods available at the time, including neutron sampling and Russian roulette techniques. The study is set against the backdrop of the need to evaluate reactor designs accurately for feasibility studies. The book delves into the approximations made in the model, such as treating the moderator as monatomic hydrogen gas, assuming a constant scattering cross-section, and using a 1/v law for all absorptions except U-235. The results obtained using these approximations show good agreement with experimental measurements for several different sizes of fuel rods and water-to-uranium ratios. The book concludes by discussing the limitations of the current model and outlines plans for a new version that will incorporate inelastic scattering effects using a quantum mechanical isotropic oscillator model of the water molecule. It emphasizes the importance of accurate thermal utilization calculations for reactor design and highlights the potential of Monte Carlo methods in this field.
