THE NURESAFE PROPOSAL

B R U N O C H A N A R O N ( C E A )

NURISP General Seminar - Karlsruhe April 2-3, 2012

� The NURESIM roadmap and objective

� The NURESFAE objectives

� Introduction to the project



Why NURESAFE ?3

1) NURESIM and NURISP projects created:

� A common European SOA simulation platform for reactor simulation

� A living community which gathers experts from Labs, university, TSO, industry

This success motivates the full completion of the NURESIM


This success motivates the full completion of the NURESIM roadmap

2) Safety of LWRs is a major stake for nuclear industry

� LWR will constitute the main part of fleets during the 21st century

� NURESIM platform can provide to utilities, vendors, TSO, the best

reactor software set for the needs of safety analysis

The NURESIM target4

• State of the art, multi-physics, multiscale� SOA, well validated, dealing with different physics and scales

• European

The NURESIM platform:


� A common European development to meet requirements fromstakeholders, share tools, knowledge and best practices

• Integrated Platform� Common functions, multiscale, multiphysics, user friendly

• For Simulation of Light water nuclear reactors� GEN II, GEN III, GEN III+

� The NURESAFE objectives



The NURESAFE objectives7

� Deliver reliable SOA software for the needs of safety analysis of LWRs

� Extend the NURESIM platform to fuel thermo-mechanics

� Many acceptance criteria are relative to cladding (1st barrier). So, good modeling of fuel is key for a realistic simulation.


modeling of fuel is key for a realistic simulation.

� Expand the use of the platform

� NURISP coupling interfaces were delivered in the 3d period of the project

Deliver software for the needs of LWR safety analysis

8

� Simulation tools will be based on NURISP codes and coupling schemes recently developed within NURISP

� Delivery of multiphysics-multiscale integrated tools to simulate some selected « situation targets » (or accidental transients)

� More predictive core thermal-hydraulics models are needed


� More predictive core thermal-hydraulics models are needed

� Simulation tools developed within NURESAFE need to be well validated.

� validation process includes uncertainties quantification

� NURESAFE software must be users friendly

Extension to fuel-thermo-mechanics

� Simulation of irradiation of the fuel in normal operation: FRAPCON

� = = > Initial conditions for the accident studies

� Fuel behaviour during LOCA transients: DRACCAR

� DRACCAR was integrated in SALOME within NURISP

Connexion of a platform T-H system code (CATHARE, ATHLET) must be


� Connexion of a platform T-H system code (CATHARE, ATHLET) must becompleted in the frame of NURESAFE

� Fuel behaviour during other accidents: SCANAIR

Expand the use of the platform10

� Individual NURESIM codes as well as integrated simulation tools developed in NURISP must be used

� The target is:

� Users in the consortium (23 partners, some of them come from the former NUG)


NUG)

� The NURESAFE users’group (5 organisations already interested by the UG)

� In an early phase of the project, we must show demonstrations of the coupling interfaces available at the end of NURISP

� Bilateral licence agreement and code deliveries have to be done earlier than NURISP
