URANIUM-GRAPHITE REACTOR IRRADIATING DEVICE FOR IRRADIATING MATERIALS Russian patent published in 2005 - IPC

FIELD: neutron transmutation doping of industrially produced silicon in fast reactors.

SUBSTANCE: proposed device primarily designed for type RBMK reactors has through flow path with bellows compensator and external shell fixed to the latter and made in the form of sleeve, build-up path, and head, all joined in tandem; sleeve is mounted through its top part on supporting shoulder of through flow path in bore of graphite blocks of neutron reflector; device is also provided with internal tube mounted in a spaced relation inside external shell, as well as with cooling liquid inlet and outlet units forming cooling system together with external shell and internal tube; ionizing radiation shielding means are installed inside and outside of external shell; device is also provided with telescopic hanger of irradiation container disposed within internal tube and joined to bottom section of hanger; the latter is provided with vertical displacement and rotation actuator disposed in upper part of external shell; sleeve condition checkup system is placed outside of external shell.

EFFECT: improved properties of doped silicon, enhanced doping uniformity, reduced trouble probability.
