The article provides an overview of the reactor dynamics code DYN3D. The code comprises
various 3D neutron kinetics solvers, a thermal-hydraulics reactor core model and a thermo …

The validation process is done to ensure the performance of nuclear codes compared to
experimental results and to determine the degree of reliability of codes output. The …

A simple low dimensional nonlinear dynamic model of the primary circuit in a VVER-type
nuclear power plant is developed from first engineering principles that is able to capture the …

One of the most intensively developing areas in the LWR multi-physics is a coupling of
different best estimate 3-D neutron kinetic (BIPR, DYN3D, KIKO3D, NEM, PARCS, etc.) and …

Low-frequency neutronic noise with magnitudes of up to ten percent of the reactor power
have been observed in Konvoi-type PWR in Germany in the last years. Several attempts …

Plant-measured data provided by the OECD/NEA VVER-1000 coolant transient benchmark
programme were used to validate the DYN3D/RELAP5 and DYN3D/ATHLET coupled code …

Plant-measured data provided within the specification of the OECD/NEA VVER-1000
coolant transient benchmark (V1000CT) were used to validate the DYN3D/RELAP5 and …

The reactor dynamics code DYN3D has been coupled with the CFD code ANSYS CFX and
the 3D thermal hydraulic core model FLICA4. In the coupling with ANSYS CFX, DYN3D …

Several three-dimensional hexagonal reactor dynamic codes have been developed for
VVER type reactors and coupled with different thermal-hydraulic system codes. Under the …

In the framework of the European project NURESAFE, the reactor dynamics code DYN3D,
developed at Helmholtz-Zentrum Dresden-Rossendorf (HZDR), was coupled with the …
