Abstract
A method for affecting neutron spectral shift in a reactor core includes providing a liquid poison in a hollow control blade extending into the core, displacing the liquid poison with a first fluid for obtaining a hard neutron spectra during a beginning interval of the core fuel cycle for converting fuel, and then increasing moderating ratio for obtaining a soft neutron spectra during an end interval of the cycle for burning the converted fuel. An exemplary apparatus for practicing the method displaces the liquid poison in the control blade with the first fluid for obtaining the hard neutron spectra. The first fluid may be either replaced, displaced, or added to by a second fluid having a second moderating ratio for obtaining the soft neutron spectra.
