Neutron Beam Design and Performance for BNCT in Czechoslovakia
Conditions for forming an appropriate neutron spectrum on the experimental reactor VVR-S at the Nuclear Research Institute at Rez near Prague were investigated. Each configuration of moderating and shielding layers is referred to as a ‘variant.’ That designated as Variant C was designed using multigroup transport codes and the results were verified by measuring neutron fluxes, neutron spectra, and the gamma-ray background. In 1988, VVR-S equipment was shut down for reconstruction of the LVR-15 reactor. New conditions for neutron beam performance therefore arose and the calculational results for Variant D were obtained. Experimental verification of the Variant D design will be realized as soon as the reconstruction is finished.
