APOLLO3®: Overview of the new code capabilities for reactor physics analysis

International audienceAPOLLO3® is the French deterministic code for lattice and core calculations, it is developed at the CEA with the financial and technical support of EDF and Framatome since 2007.The main goal of APOLLO3® is the development of a unique deterministic tool which includes the capabilities of lattice and core French codes of previous generation, e.g. APOLLO2, CRONOS2, ECCO and ERANOS, while providing large improvements on reactor physical modeling in a modern and flexible software architecture platform for R&D and industrial activities.This paper presents an overview of the new main capabilities of the deterministic APOLLO3® code in the lattice and core components
