Uncertainty in the dynamic behaviour of a fast breeder reactor to delayed-neutron energy spectra
- 1. Bhabha Atomic Research Centre, Bombay (India). Theoretical Physics Div.
Description
Uncertainties in the kinetic response of a 500 MWe Prototype Fast Breeder Reactor design to large changes in delayed-neutron energies have been calculated using point kinetics method and the concepts of Delayed Spectrum Factor and Beta Growth Factor. Positive reactivity accidents are postulated. Calculations show that delayed-neutron spectra have little influence on the shapes of the transients, though the spread is within about 27% for the peak power attained and about 20% for the accident energy released. However, the relative power level shows a much greater sensitivity. (author). 5 refs., 3 tabs
