Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

A reference low-activation vanadium alloy NIFS-HEAT-2 was neutron-irradiated at 450 °C and below, in order to estimate the resistance to low temperature irradiation. DBTT of NIFS-HEAT-2 was -85 °C after irradiation up to 8.5 dpa at 450 °C in Na atmosphere, while DBTT was below -196 °C for 3.7 dpa at 430 °C in Li atmosphere. On the other hand, DBTT was lower than about -90 °C for the irradiation up to 0.1~1 dpa at 60, 290 and 400 °C. The DBTT shift was increased with increasing hardness after neutron irradiation for limited irradiation conditions. The mechanisms of DBTT shift and irradiation hardening at low temperature was discussed.
