McDonald, D. L.

In an effort to determine if point defects produced in BeO by fast neutron bombardment were mobile at room temperature, a specimen was irradiated below 100 un. Concent 85% K; and thermal conductivity measurements were made in- pile during the irradiation and during a subsequent isochronal annealing study between 100 un. Concent 85% K and room temperature. Thermal resistivity increased linearly with fast neutron dose, and damage recovery started at 100 to 110 un. Concent 85% K and continued at about a constant rate up to maximum temperature. The results indicate defect mobility should be taken into account for below room temperature.
