FIELD: physics.
SUBSTANCE: method for assembling the absorber element (AEL) of a nuclear reactor includes preparing the shell in the form of a tube, sealing it by argon-arc welding at one end by the lower ferrule having a conical shape, loading the shell by the absorber materials in the form of pellets or powder, fixing the absorber material from the axial displacement with the gasket installation in the powdery state of the absorber material, sealing the shell at the other end by the contact-butt welding by using the upper ferrule containing a weighting part. Fixing the absorber material from the axial displacement is performed by a spring retainer mounted in the compensation amount of the AEL.
EFFECT: invention allows to increase reliability of the method for assembling the absorber element and to increase performance while maintaining efficiency of the absorber element.
