New code version, List of publications updated. Complex geometries with highly-refined spatial detail are also encountered in various fusion applications.

Multiple versions of the same database exist for example, test and production. The spatial integration domain can be defined by a combination of cells, universes, lattices and materials, or using a three-dimensional super-imposed mesh. As a general rule, more than one set of RECON data sets is necessary guidw all the following conditions are true:. May 19, Ville Valtavirta defended his Doctoral Thesis: The calculations also demonstrated the practical feasibility of using the continuous-energy Monte Carlo method for producing the full set of group constants for full-scale PWR fuel cycle simulations.
October 13, M. Energy deposition and radiation dose can also be evaluated using refedence detector types, which in some case provide more physical results compared to the use of flux-to-dose conversion factors.
Subsystem records contain information about the subsystem and related recovery information, including:. Systematic validation for criticality safety analyses using experimental configurations and data from the International Handbook of Evaluated Criticality Safety Benchmark Experiments is currently under way.
Prevention and Detection for the Twenty-First Century. Photon transport mode Photon physics routines were implemented in Serpent 2 in Kaltiaisenaho, This class of records includes: The results are given both as material-wise and total values.
The original data set. Comparison of effective multiplication factors and other integral parameters shows generally good agreement between different calculation codes, but significant discrepancies can be found in the concentrations of individual nuclides.
Work on coupled multi-physics applications continues. Calculations can be divided into several nodes by distributed-memory MPI parallelization.
As last year, this method of publication replaces the data dvd publication used in previous years. The first data set is known as copy1. The results can be divided into an arbitrary number of energy and time bins. The lowest optimization modes allow running large burnup calculation problems with tens or hundreds of thousands of depletion zones, while the higher modes provide considerable speed-up in assembly-level calculations.

It will help us if you say what assistive technology you use. In this case, the 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 recommended publication for referencing Serpent is: CAD models are read in the stereolitography STL format, in which the surfaces of geometry bodies are represented by a mesh of flat triangles.
Presentations available for download. It contains the same information as the copy1 data set.
Built-in mass-energy attenuation coefficients are available for calculating photon dose rates. The built-in solvers are integrated to the transport simulation at guive code level, and designed to provide solutions to coupled problems at a relatively low computational cost.

Department of Referrnce and Social Care. Development and applications of multi-physics capabilities in a continuous energy Monte Carlo neutron transport code at Aalto University. January 6, NEA Base version upgraded to 1.
If one becomes unavailable, the spare will be activated if it is available. All numerical output is written in Matlab m-format files to simplify the post-processing of the results. It will take only 2 minutes to fill in. Validation Each Serpent update is checked by comparison to MCNP by running a standard set of assembly calculation problems.
The best way to validate the Monte Carlo based code sequence is to compare the results to reference Serpent full-core calculations. January 31, Beta-testing phase of Serpent 2 started.
Burnup calculations referrence extremely sensitive to differences in the fundamental physics data, and changing one decay library to another can alone result in orders of magnitude discrepancies for some radionuclides.
Request an accessible format. Transport cross sections and diffusion coefficients calculated using several methods. The standard tally types are based on the collision estimate of particle flux, and special detectors are available for calculating surface currents and reaction rates inside simple surface types using the track-length estimator. The source distribution for photon transport simulations can be obtained from a radioactive decay source.
