The Temperature and Neutron Dose Dependence of Irradiation Growth in Zircaloy 2

Source

Irradiation growth due to fast neutron bombardment has been measured in textured Zircaloy 2 as a function of neutron dose (ϕt) and irradiation temperature. The growth strain ε obeys a relationship ε∝ (ϕt)n over a temperature range -196 to 280 C and for doses up to 1021 n/cm2. For irradiation temperatures up to 80 C, n = 0.4; but at 280 C, n = 0.7. The temperature dependence of irradiation growth in Zircaloy 2 is small, and in the temperature and dose ranges considered the growth strains do not differ by more than a factor of four. The growth rate Gd ε/dt) is initially large at low doses but approaches 1 at high doses (∼;1021 n/cm2).
