The X2 VVER-1000 benchmark provides a unique set of the operational data of a VVER-
1000 reactor. This includes fresh core hot zero power (HZP) experiments, operational history …

The Kraken computational framework is a new modular calculation system designed for
coupled core physics calculations. The development started at VTT Technical Research …

This paper presents the development of a nodal diffusion code, RAST-V, and its verification
and validation for VVER (vodo–vodyanoi energetichesky reactor) analysis. A VVER analytic …

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 …

Verification of operation parameters of VVER-1200 NPP Simulator installed at Nuclear
Training Center, VINATOM has been performed. This simulator has been supplied for …

The objective of this paper is to start the validation of the coupled code system of the nodal
neutronics solver Ants and the system code TRACE. The process consists of two exercises …

Abstract SIMULATE5-K-VVER (S5K-VVER) is the newest addition to the CMS5-VVER
modeling suite developed by Studsvik Scandpower, Inc.(SSP). In S5K-VVER, the coupled …

The switching off of the one of four main circulation pumps results in the Kalinin-3 Coolant
Transient Benchmark. The benchmark contains four exercises, but this article shows the …

This paper presents the verification results of our inhouse code RAST-K for Kalinin-3 NPP
Benchmark compared to ATHLET/KIKO3D and PARCS nodal codes [1][2][3][4][5]. Kalinin-3 …

The best estimate simulation of three-dimensional phenomena in nuclear reactor cores
requires the use of coupled neutron physics and thermal-hydraulics calculations. However …
