THE NA BONDING PIN CONCEPT FOR ADVANCED FUELS. PART II - ANALYSIS OF THE CLADDING CARBURIZATION
A set of calculations have been carried out with the code system EUGES-ARIES, to study the swelling performance limits of a Na bonded mixed carbide pin design, which was recently adopted for introduction of advanced fuels in LMFBR's. The results indicate that a useful peak burn-up of 150.000 MWd/t can be attained with pin diametral deformations up to 2 %, under optimal irradiation conditions. However, probable thermal disturbances in the fuel and cladding mechanical deterioration due to steel carburization, still represent a risk source for pin failure. A further improvement of the swelling performance of MC is therefore needed to consolidate the examined pin design for future full scale reactor applications.
