The behavior of a B/sub 4/C-phenolic and a glass-fiber-reinforced B/sub 4/C-phenolic composite in a spent nuclear fuel storage pool
A three-part experimental study has been carried out to determine the effects of exposure to the spent nuclear fuel pool environment on two composite neutron-absorbing materials--one made in plate form and consisting of about 72 wt% of B/sub 4/C particles bonded together by about 28 wt% of a phenol-formaldehyde polymer, and the other made in sheet form and consisting of about 62 wt% of B/sub 4/C particles bonded to both sides of a woven glass-fiber reinforcement by about 19 wt% of the same polymer. The results of the mechanical and physical properties tests show that the two materials degrade somewhat differently in the spent fuel pool environment. In the case of the plate material, radiation-induced expansion and embrittlement of the polymer lead at doses about 10/sup 9/ Gy to about 1% linear expansion, with a concomitant about 60% reduction in strength and stiffness and a somewhat enhanced sus-
