Ng. Primakov et al., Nonuniform swelling and hydrogen redistribution in zirconium hydride underneutron irradiation, INT J HYD E, 24(9), 1999, pp. 805-811
Swelling, hydride composition. distributions of microhardness and thermoele
ctric power in cross sections of zirconium hydride samples irradiated in th
e BN-600 reactor with neutron fluence of similar to 6.0.10(26) n/m(2) (E >
0) in the temperature range of 670-770 K have been investigated, A correlat
ion of microhardness increment and swelling has been established. Swelling
in outer layers of materials turned out to be twice of that in inner ones.
This fact is due to variations of neutron flux and energy release-radiation
heat generation ina bulk of zirconium hydride under fission gamma ray and
neutron irradiations. (C) 1999 International Association for Hydrogen Energ
