Abstract

PURPOSE: To limit a reduction to minimum of the degree of burn-up from taken out fuel assembly, as well as to promote an improvement of shut-down margin, by means of lowering down a neutron flux on top of the fuel assembly at the time of reactor shut-down.
CONSTITUTION: For the fuel pellet packed to a portion about 10 to 60cm above the fuel assembly of equal length to an effective length of the reactor control rod, is used a slightly enriched uranium pellet with an enrichment of uranium 235 slighter than that in other portion or natural uranium pellet. A packing of the slightly enriched uranium or natural uranium is not always required for all of the fuel assembly, but partially for some number of the fuel assembly determined by a reactor shut-down margin required.
