- Summary
- An equation for neutron age as a function of composition for homogeneous systems was derived, taking into account the slowing down and transport cross section terms. Neutron age for enriched uranyl fluoride ( approximately 90% U- 235) in water was calculated by the equation as a function of H/U-235 using 27 cm/ sup 2/ as the neutron age in pure water. For H/U235 values > 200 there is essentially no water displacement. For H/U-235 values <55 the rate of increase of neutron age is controlled by the rapid displacement of water by fuel. The neutron age at an H/U-235 value of 45 is about 29.8 cm/sup 2/. For such H/U-235 ratios, the effect of epithermal captures on reactivity is discussed. (C.J.G.)
