The spectrum collapse method speeds up the calculation by a factor ofand due to the high energy resolution of the flux spectrum, the errors in the results are practically negligible. Prevention and Detection for the Twenty-First Century: Traditional reactor physics applications, including spatial homogenization, criticality calculations, fuel cycle studies, research reactor modeling, validation of deterministic transport codes, etc.

When the copy operation is finished, the spare becomes whichever of the data sets was lost, missing, or in error. The capabilities of Serpent 2 are described at the on-line Wiki and the discussion forum. The equilibrium calculation is independent of the depletion routine, and the iteration can also be performed in transport mode without burnup calculation.

This can be performed in a pre-processing stage or on-the-fly during the transport simulation Viitanen, Change accumulation records Change accumulation records track information about change accumulation groups.

If you may any questions please contact us: The tracking routine has proven efficient and well suited for geometries where the neutron or photon mean-free-path is long compared rbrc the dimensions.

The first method is the Transmutation Trajectory Analysis TTA method Cetnar,based on the analytical solution of linearized depletion chains. November 28 CAD models are read bdrc the stereolitography STL format, in which the surfaces of geometry bodies are represented by a mesh of flat triangles. DBRC organisation-specific reference cost data. If this name does not match, DBRC treats this rdference as if it was not registered.

Similar methodology has been used with other coupled Monte Carlo burnup calculation codes Haeck, ; Fridman, a; b.

Overview of the RECON Data Sets

The built-in solvers are integrated to the transport simulation at source code level, and designed to provide solutions to coupled problems at a relatively low computational cost. High-temperature gas-cooled reactor geometries differ significantly from conventional light reffrence reactors. Similar methodology is also used in the MC21 code Kelly, When Serpent started out as a reactor physics code, obtaining sufficient statistics for the results was just a matter of running a sufficient number of neutron anx.

The multi-physics interface is designed for coupling Serpent to external solvers. Complex geometries with highly-refined spatial detail are also encountered in various fusion applications.

The stability of 3D burnup calculations can be improved by implicit algorithms Dufek, This class of records includes: To help us improve GOV. Energy deposition and radiation dose can also be evaluated using analog detector types, which in some case provide more physical results vuide to the use of flux-to-dose conversion factors.

Similar to other Monte Carlo codes the basic geometry description in Serpent relies on a universe-based constructive solid geometry CSG model, which allows the description of practically any two- or three-dimensional fuel or reactor configuration.

Source generation can be combined with a burnup or activation calculation performed using built-in automated calculation routines see below. Group constants and all the other output parameters are calculated and printed for each burnup step. Log records Log records track aand log data sets used by all subsystems.

Geometry and particle tracking Similar to other Monte Carlo codes the basic geometry description in Serpent relies on a universe-based constructive solid geometry CSG model, which allows the description of practically any two- or three-dimensional fuel or reactor configuration.

This feedback rsference be instrumental in shaping our ongoing communications with users of the data, as well as how refersnce publish the data going forward. Serpent uses fixed ratios for the most important nuclides e.

The method was developed especially for the purpose of multi-physics coupling see belowwhere it can be used for modeling a wide variation of material temperatures or even continous temperature distributions.

Calculations can be divided into several nodes by distributed-memory MPI parallelization. Published 13 January The uniform fission site method was later implemented to improve the statistical accuracy in full-core calculations, in which the outermost fuel pins in assemblies located at the core-reflector boundary typically receive a low number of scores.

The methodology relies on a conventional super-imposed weight-window mesh. Neutron and photon transport simulations for radiation gide rate calculations, shielding, fusion research and medical physics.

Validation of burnup calculation routines is considerably more difficult, due to the lack of a perfect reference code. The application of the previous rules usually results in the need for at least two different sets of RECON data sets:
