In this case, guidf test database with a DSN different than the production database, even if with the same DBD name and data set name, can coexist with the production environment, but not under the control of DBRC. The spatial integration domain can be defined by a combination of cells, universes, lattices and materials, or using a three-dimensional super-imposed mesh.

In addition to the particle transport simulation, parallelization in the burnup calculation mode divides also the preprocessing and depletion routines between several CPU’s. Two-way coupling to thermal hydraulics, CFD and fuel performance codes has been a major topic in Serpent development for the past several years.

Drc a general rule, more than one set of RECON data sets is necessary if all the following conditions are true:. March 19 Photon transport mode Photon physics routines were implemented in Serpent 2 in Kaltiaisenaho, The original incentive for developing a photon transport mode was to account for gamma heating in coupled multi-physics simulations.


Interaction data is available for nuclides at 6 temperatures between and K.

Serpent started out as a simplified reactor physics code, but the capabilities of the current development version, Serpent 2, extend well beyond reactor modeling. The equilibrium calculation is independent of the depletion routine, and the iteration can also be performed in transport guidee without burnup calculation.

October 13, M.

Internal coupling to built-in solvers for fuel behavior and thermal hydraulics. This feedback will be instrumental in shaping our ongoing communications with users of the data, as well as how we publish the data going forward. The dbgc coupling scheme in Serpent 2 is designed to operate on two levels: Output for burnup calculation consists of isotopic compositions, activities, spontaneous fission rates, decay heat and radiotoxicity data.

The first method is the Transmutation Trajectory Analysis TTA method Cetnar,based on the analytical solution of linearized depletion chains. Energy, 82 Similar validation project is planned for radiation shielding calculations. Burnup calculation The burnup calculation capability in Serpent was established early on, and is entirely based on built-in calculation routines, without coupling anr any external solvers. This work is an essential part of expanding the use of Serpent to fusion research.

DBRC always reads from this data set, and when some change has to be applied, the change is written first to this data set. Traditional reactor physics applications, including spatial homogenization, criticality calculations, fuel cycle studies, research reactor modeling, validation of yuide transport codes, etc.


Secondary photons are produced by atomic relaxation and bremsstrahlung, handled using the thick-target bremsstrahlung TTB approximation.

This is strongly recommended. This class of records includes change accumulation group, execution, and data set records.

May 26, Serpent 1. The method has been validated with good results and the routine works efficiently referenxe significant computational overhead. The spectrum collapse method speeds up the calculation by a factor ofand due to the high energy resolution of the flux spectrum, refeernce errors in the results are practically negligible.

As part of our ongoing review process we are very keen to know the breadth of users who are utilising the organisation level reference costs data.

Log records Log records track the log data sets guidee by all subsystems. The only record type in this class is a DBDS group record. The number of depletion zones is not restricted, although memory usage may require reducing the optimization when the number of burnable materials is large.

Photon tallies also include a pulse-height detector. Radioactive decay and fission yield data used in the calculation is read from standard ENDF format data libraries. Differences to other Monte Carlo codes Keno-VI are small, but statistically significant discrepancies can be observed in refeernce cases.
