Core Library for Advanced Scenario Simulation :

CLASS is a dynamical fuel cycle simulation tool. It allows to simulate the evolution of an entire nuclear reactor fleet and its associated facilities, such as spent fuel pool, fuel fabrication plant, chemical separation plant, disposal and so on.

CLASS is developed from a CNRS/IRSN collaboration started in 2012. It is an open source package of C++ libraries.

CLASS main asset is its ability to include any kind of reactor, either the system is innovative or standard. Indeed, the opportunity is given to each user to build his own reactor data bases and models. CLASS aims to be a useful tool for scenarios studies involving Generation IV reactors transitions as well as innovative fuel cycles, such as the Thorium cycle.
