CIRCEE is a calculation code developed by the French Atomic Energy Commission (CEA), allowing fast assessment of operational dose over complex geometries. It is used to assess dosimetric consequences of a criticality accident. More specifically, it can be used both during the preliminary studies phase (isodoses curves for safety report preparation or emergency preparedness, CAAS implantation and validation) and during crisis management (effective dose estimation, emergency response).An early development stage of CIRCEE has been presented in a talk at the 2009 NCSD edition. Since then, a heavy code rewriting increased its reliability and maintainability while keeping its performance at an excellent level. Now in a stable production version, and following the grant of several international patents, it's aiming to short term availability for the industry.
