... and molten salt erosion. Nuclear graphite, as a moderator and reflector for the MSR, may receive more irradiation dose than other nuclear materials inside the reactor core. Graphite is also a porous material, and impregnation of molten salts may cause damage to its internal structure. Moreover, the effects...
