The ages to the indium 1.46-eV resonance, of “point source” 235U thermal-fission neutrons in mixtures of ThO2-D2O-H2O have been measured in a lattice in which the volume ratio of moderator-to-aluminum-clad thoria pellets was 1.00 and the square pitch was 0.548 in. The results are
D2O Concentration, mol% | Age, cm2 |
0.016 (ordinary water) | 49.7 ± 2.5 |
49.77 | 67.4 ± 3.5 |
69.19 | 81.6 ± 1.5 |
79.19 | 97.6 ± 3.4 |
90.00 | 118.8 ±4.5 |
