A Y‐Ba‐Cu‐O superconductor was irradiated at 360 K in the NRX reactor, with a well‐thermalized flux of 1.82 × 10 17 n/(m 2 ·s) (E < 1 MeV). Superconducting characteristics at 90 K disappeared by a fluence of 6.6 × 10 21 n/m 2 (10 h) but were recovered after a postirradiation heat treatment at 760 K in flowing oxygen. The results suggest that suitable shielding will be required for any application which exposes the superconductor to neutron irradiation.
