Abstract:
Unit-cell calculations for plutonium fuelled pebbles of the HighTemperature Gas-cooled Reactor, were performed with WIMS, SCALE and MCNP. The
k_#infinity# and spectral parameters, especially introduced for the plutonium
fuel, have been calculated, for pebbles with a varying plutonium mass per
pebble and with different type of coated particles. For one pebble geometry,
the mentioned parameters have been calculated for various fuel temperatures
and over-all (uniform) temperatures. For the same pebble geometry, burnup
calculations were carried out with WIMS and SCALE/ORIGEN-S. This document put
emphasis on the comparison of the calculational results, but gives in
addition reactor physics interpretations on some calculational results. 40
