Dimensional contraction of impregnated and base stock HLM-85 graphite ranged from 0.25 to 0.85% in the perpendicular direction and from 0.84 to 1.60% in the parallel direction when irradiated at 650 and 1000 deg C to 7 x 10/sup 21/ nvt (E> 0.18 Mev). The diameters of disk samples cut from the wall of a full- size impregnated HLM-85 sleeve contracted 0.20 and 0.10% when irradiated at 550 and 900 deg C, respectively, to 1.65 x 10/sup 21/ nvt (E> 0.18 Mev). Electrical resistivity was increased by a factor of about 1.5to 3. Thermal expansion coefficients were increased about 10% in the parallel direction. Line broadening of (002) line profiles was observed for samples irradiated at 650 and 1000 deg C but the C/sub o/ spacing was relatively unchanged. The impregnation treatment had little effect on the changes in properties, which result from fast-neutron bombardment. (auth)
