Closed U-Pu and Th-U cycle in sixteen selected reactors: Comparison of major equilibrium features

Popis výsledku v původním jazyce

In this study the performance of sixteen selected reactor types, eight thermal and eight fast, was evaluated in both U-Pu and Th-U equilibrium fuel cycles. The reactor types were selected so that all major designs and spectra are covered. Even though the equilibrium composition and spectrum mutually influence each other, the general spectrum shape is determined by the relative strength of coolant and structural materials scattering properties. EQL0D v2 MATLAB procedure coupled to the SERPENT 2 code was used for the simulation. Several simplifying assumptions have been applied to enumerate the eigenvector of Bateman matrix; the reprocessing losses were zero, the FPs were neglected and instantaneously replaced by either 238U or 232Th feed, the reactors were represented only by an infinite lattice, and the generated power was fixed at nominal value independently from the criticality or subcriticality level and fissile fuel share.
