METHOD OF RECOVERY OF RESOURCE CHARACTERISTICS OF RBMK REACTOR Russian patent published in 2015 - IPC G21C1/06 

FIELD: power industry.

SUBSTANCE: at deflection of the columns installed in the active zone by rows, from them the channels are taken out, graphite blocks of these columns are cut along sides into fragments, the fragments displaced in the direction, perpendicular to the cut plane, and deflections are reduced then holes of columns are calibrate and the channels are placed there again. The blocks of columns without adjacent sides installed, at least, in rows from the 7^th and to the 15^th, if to count from the active zone centre. In blocks of columns two or four opposite cuts are made, and fragments are displaced step by step from internal rows to the external ones. Besides, in addition the blocks of columns can be cut in rows from the 17^th and to the 19^th row, if to count from the active zone centre.

EFFECT: increase of reliability and profitability of recovery work, decrease their duration and dose loads on the personnel.
