The thermal conductivity of neutron-irradiated reactor-grade graphites made from needle coke (H-327), Gilsocoke (H-328), and isotropic petroleum coke (H-451) was measured between 22 and 800ยฐC. Irradiation temperatures were between 600 and 16OO"C, and fast neutron fluences ranged up to lO22 n/cm\* (E
Changes in crystal lattice parameter, c-axis lattice strain and apparent crystallite height induced by neutron irradiation at 72G135O"C were investigated by means of X-ray diffraction for fourteen specimens which included five bands of nuclear graphite and two kinds of pyrolytic graphite. All irrad
observed etch-patterns seem to have no relation with the dislocation content of the crystals. The imphcations are discussed.
