Expressions for the diffusion cooling coefficient and the coefficient of B2 term have been derived both on diffusion and transport theory. Using the Nelkin kernel in the incoherent approximation and transport cross sections as given by Singwi, these parameters have been evaluated for BeO moderator. Numerical calculations have been done with an energy mesh of 0·9 meV and cut-off energy of 0·3 eV.The theoretical value of 3·4 × 105 cm5 sec−1 for the diffusion cooling coefficient is on the lower side of the experimental value which lies between (3·5–6) × 105 cm4 sec−1. In view of the large experimental errors on F-coefficient, no conclusion could be drawn.On the basis of the theoretically calculated negative F-value, one concludes that the thermalization power for BeO decreases with a decrease in neutron temperature.</div>","PeriodicalId":100815,"journal":{"name":"Journal of Nuclear Energy.

The 298U(n, γ) reaction rate was measured by counting the 239U activity produced and the (n, f) reactions were monitored by counting the fission neutrons emitted. The spherical symmetry of the apparatus was chosen to minimize any effects of thermal expansion and to facilitate the comparison of the results obtained with those from a computer calculation based on a programme developed by Brissenden and Durston. In this programme a statistical distribution of resonances based on resolved resonance data is tabulated over a fine energy mesh. This tabulation was used in a 4-region slowing down calculation resulting in a region-dependent neutron spectrum from which the particular reaction rates at various temperatures were obtained.</div>","PeriodicalId":100815,"journal":{"name":"Journal of Nuclear Energy.
