METHOD FOR EVALUATING THE SERVICE LIFE OF VVER-1000 FUEL-ELEMENT CLADDING IN DIFFERENT LOADING REGIMES

摘要

A method for evaluating the service life of VVER-1000 fuel-element cladding in constant and variable fuel load regimes is proposed. It is shown that a comparative assessment of the service life of cladding with different core regimes and parameters is possible on the basis of the energy approach to creep and destruction of cladding.
