Abstract
  The effective β-fraction has a key role in the dynamic response of the reactor. This study aims to assess the suitability and accuracy of the detailed models of DRAGON5 and DONJON5 code for estimation of the effective fraction of delayed neutron for the VVER-1000 reactor core. DRAGON5 is adopted ...  Read More

Abstract
  ‎Thorium is more abundant in nature than uranium‎. ‎The fertile thorium fuel can breed to fissile U-233 by absorbing a neutron‎. ‎The produced fissile has good neutronic performance in both thermal and fast neutron spectra‎. ‎Many types of thorium-based fuels were applied ...  Read More
