INVESTIGATION METHOD OF RADIATION RACK OF STRUCTURAL MATERIALS, AND CONTAINER FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC H05H6/00 

FIELD: heating.

SUBSTANCE: specimens of different types are prepared and arranged in an extraction container that is arranged in the reactor core. Three specimen irradiation zones are formed as to the container height. Lower and upper specimen irradiation zones are formed in the area of maximum gradient of neutron flow intensity and damaging irradiation doses as to height of the reactor core. Temperature of specimens of lower and middle zones is built with the specified heat carrier flow. Temperature of specimens of the upper zone is built due to their heating at irradiation in static heat carrier medium in a sealed ampoule heat insulated from flowing heat carrier. The middle zone includes several groups of identical specimens, which are arranged in pairs as to height of the extraction container. After the specimens are irradiated, the extraction container with specimens is extracted from the reactor core. Measurements, tests and investigations of properties of the irradiated specimens are performed and relationships between mechanical, physical properties and radiation stability of the investigated materials and temperature and irradiation dose are established.

EFFECT: increasing scope and reliability of information as per properties of irradiated specimens.
