Abstract
PANTHERE is a multipurpose radiation protection software developed by EDF to calculate gamma dose rates in complex 3D environments. PANTHERE takes a key role in the EDF ALARA process, enabling to predict dose rates and to organize and optimize operations in high radiation environments. PANTHERE is also used for nuclear waste characterization, transport of nuclear materials, etc. It is used in most of the EDF engineering units and their design service providers and industrial partners.
Highlights
PANTHERE is a radiation protection code used for 3D simulation of gamma dose rates and fluence for complex environment with distributed radioactive sources like nuclear facilities
PANTHERE’s computation kernel uses CEA solver NARMER, which is linked to the EDF R&D geometric library LIBCAD
This chapter focuses on the different physical models used by NARMER
Summary
PANTHERE is a radiation protection code used for 3D simulation of gamma dose rates and fluence for complex environment with distributed radioactive sources like nuclear facilities. PANTHERE is intensively used by EDF engineering units and its industrial partners. It was originally used to prepare maintenance and modification operations in nuclear power plants, especially on the primary circuit like pressurizer heaters replacement and steam generator replacement. It is extended to other fields like: - shield design and zoning for EPR reactors - dose calculations for the qualification of PWR equipments during severe accidents. - decontamination and dismantling operations - radiological characterization for applications associated to transport and nuclear waste management. PANTHERE is verified and validated by comparison with the reference Monte Carlo code TRIPOLI-4 of the CEA and gamma dose rates experimental measurements
