Abstract

Fuel element for a nuclear reactor which originally does not have a balance of samcrium has a superfluous reactivity to compensate for the growth of Samarium in the fuel element during operation there is also an original amount of combustible poison in the form of an oxide, which compensates for the initial lack of samarium and has a cross-section which, with rising neutron energy, falls more sharply than samarium-149.
