AMPULE DEVICE FOR THE REACTOR STUDIES Russian patent published in 2019 - IPC G21C17/06 

FIELD: nuclear equipment.

SUBSTANCE: invention relates to the nuclear equipment, in particular, to the ampoule irradiating devices for the fuel elements properties reactor studies. Ampoule device for the reactor studies includes the outer cylindrical shell with sealing end caps, inside of which at least one capsule is located, enclosed in the sealed shell and equipped with gas mainlines for its flow-through ventilation. Inside the capsule the investigated samples are located, placed in the common thin-walled shell from the refractory material. Each capsule is equipped with a screen of refractory material, installed coaxially with the gaps between the hermetic capsule shell and the shell with the samples placed therein. At that, the gap between the shell with the samples placed therein and the screen effective cross section value does not exceed the gas mainlines minimum cross section value.

EFFECT: technical result is the ampoule device development for reactor studies, allowing to study the samples under investigation swelling kinetics during the experiment.
