The Dependency of Reactivity of Burn-up in Fast Reactors
In fast reactors the poisoning effects of fission products are reduced because of relative low capture cross sections at high energies. In addition, in fluid fuel reactors there is the possibiity of removing them by processing. If plutonium production is of secondary importance to power production, then higher burnup of fuel is possible and dependency of reactivity on burnup becomes a problem of interest. One-group calculations are performed as a first step in understanding the relative effects of the initial breeding ratios, enrichment, and fissin product and heavy isotope concentration.
