DEVICE TO LOAD AND TEST SAMPLES IN CHANNEL OF NUCLEAR REACTOR Russian patent published in 2014 - IPC G01N3/18 G01N3/02 

FIELD: testing equipment.

SUBSTANCE: device comprises a unit of sample fixation, a unit of load creation and adjustment, a unit to monitor change of sample parameters. The unit of load creation and adjustment is made in the form of a bellows rigidly connected on top with a long flexible pipe, which is connected with an external source of gas supply, and the bottom of the bellows is tightly closed. The unit of sample fixation is arranged outside the bellows and comprises two parts: upper and lower, every of which comprises the first and second elements for fixation of the sample rigidly connected with the appropriate traction rod. The first element for fixation of the sample in its upper part via the first traction rod is rigidly connected with the external side of the bellows top, and the second element for fixation of the sample in the lower part via the second traction rod is rigidly connected with the external side of the bellows bottom. The unit of control over variation of sample parameters is fixed on traction rods between the first and second element for fixation of the sample. The distance between the bottom of the bellows and the first element for fixation of the sample exceeds the possible tension of the sample under maximum load.

EFFECT: expansion of the field for testing of samples.
