IRIS: Monte Carlo Results for Selected Ex-Core Radiation Responses. Open Version

Results for ex-core radiation responses in the IRIS reactor design obtained with the Monte Carlo method are presented at the preliminary design stage. The responses include pressure vessel damage, dose during running outside the biological shield and in the seismic isolator zone, maintenance doses in the pressure vessel well and in the cavities inside the containment vessel above and below the main deck level, doses al EOL around an extracted steam generator and around the extracted reflector and barrel, EOL activity of the reflector and barre, and EOL activity of the pressure vessel liner, pressure vessel, concrete liner and concrete surrounding the pressure vessel well. Substitution of the concrete surrounding the pressure vessel well by carbon steel is considered (only in terms of EOL activity).
