On the Multiple-Pin Modeling of the Fuel Bundle for the Simulation of the Initiating Phase of a Severe Accident in a Sodium Fast Reactor

Autor: C. Suteau, M. Guyot, P. Gubernatis

Publikováno v: Nuclear Science and Engineering. 178:202-224

Numerical simulations of the primary phase of a hypothetical core disruptive accident are currently based on a multiple-channel approach, which requires that subassemblies or groups of subassemblies be represented together as independent channels. Ge

An Assessment of Corewide Coherency Effects in the Multichannel Modeling of the Initiating Phase of a Severe Accident in a Sodium Fast Reactor

Autor: J. Lecerf, R. Le Tellier, P. Gubernatis, M. Guyot, C. Suteau

Publikováno v: Nuclear Technology. 185:21-38

To consolidate the safety assessment for liquid-metal fast breeder reactors (LMFBRs), hypothetical core disruptive accident (HCDA) sequences have been extensively studied over the past decades. Num...

Reactivity Perturbation Formulation for a Discontinuous Galerkin–Based Transport Solver and Its Use with Adaptive Mesh Refinement

Autor: R. Le Tellier, Damien Fournier, C. Suteau

Publikováno v: Nuclear Science and Engineering. 167:209-220

Within the framework of a Discontinuous Galerkin spatial approximation of the multigroup discrete ordinates transport equation, we present a generalization of the exact standard perturbation formula that takes into account spatial discretization-indu

Analysis of an a posteriori error estimator for the transport equation with SN and discontinuous Galerkin discretizations

Autor: Damien Fournier, C. Suteau, R. Le Tellier

Publikováno v: Annals of Nuclear Energy. 38:221-231

We present an error estimator for the S N neutron transport equation discretized with an arbitrary high-order discontinuous Galerkin method. As a starting point, the estimator is obtained for conforming Cartesian meshes with a uniform polynomial orde

Development and first application of a new tool for the simulation of the initiating phase of a severe accident on SFR

Autor: C. Suteau, P. Gubernatis, M. Guyot

Publikováno v: SNA + MC 2013 - Joint International Conference on Supercomputing in Nuclear Applications + Monte Carlo.

In order to improve the safety level of Sodium Fast Reactors, low probability events such as Hypothetical Core Disruptive Accident (HCDA) are analyzed for their potential consequences. The initiating phase of such accidents is of particular interest

Status of CONRAD, a nuclear reaction analysis tool

Autor: B. Habert, O. Litaize, Gilles Noguere, C. De Saint Jean, C. Suteau

Publikováno v: ND2007.

The development of a software tool (CONRAD) was initiated at CEA/Cadarache to give answers to various problems arising in the data analysis of nuclear reactions. This tool is then characterized by the handling of uncertainties from experimental value
