Deuterium permeation properties of beta-irradiated and unirradiated poly(vinyl alcohol) and polystyrene shells
We measured the permeability of inertial fusion (IF) fuel shells made of poly(vinyl alcohol) (PVA) and polystyrene (PS) with deuterium. Activation energies of permeation (E/sub p/) were determined using permeability coefficients measured over the temperature range 25--100/sup 0/C for PVA, and -100 to 25/sup 0/C for PS shells. We then exposed this same batch of shells to intense beta irradiation from tritium and repeated the permeation measurements. Comparing permeabilities of the same shells before and after irradiation, we obtained a measure of the effect beta irradiation has on fuel retention characteristics of the polymers. Our results show that irradiation does change the permeability of PVA, while the permeability of irradiated PS is relatively unchanged.
