Calculus of a serious reactor accident – Nuclear Energy Sector

Client's issues


Evaluate accidental situations able to lead to the fusion of the core of the reactor within the framework of Safety Probabilities Studies

Our interventions

 Develop ASTEC data set for the 1300 Mwe (electric Mega watt) level
 Realisation of calculus of the pressurisation of the enclosure during the long term phase of a serious accident (with CPA for thermal hydraulic calculus of the enclosure)
 Realisation of calculus of raft erosion  (floor of the enclosure) of a 1300 Mwe enclosure with MEDICIS

Our tools & our skills

 Code ASTEC (modules CPA and MEDICIS) to model the whole grave accident
 Installation REP (Pressurized Water Reactor)
 Knowledge of Thermal hydraulics
 Physics of grave accidents
