This paper presents recent progress of the development and implementation of the integral
transport variational nodal method (VNM) to the neutronics modelling of hexagonal …

Effective strategies for maintaining reactor reactivity at a consistent level are indispensable
to enable soluble boron-free (SBF) operation in innovative small modular reactor (i-SMR) …

Homogenized macroscopic cross-sections (XS) are necessary for running core-wise nodal
diffusion calculations. XS sets are usually generated using time-consuming lattice physics …

Super-homogenisation (SPH) factors were generated by a modified version of the code
DYN3D for PWR fuel assemblies in hot-zero-power states defined in the OECD MOX/UO2 …

In this paper, the transient pin-power reconstruction based on source-expansion method has
been proposed. The transient calculation is sufficient to simulate the reactor-physics process …

The pin-by-pin method with homogenization performed at the pin cell level is of
considerable interest in thermal reactor physics calculations. However, significant …

Performing three-dimensional pin-by-pin full core calculations based on an improved
solution of the multi-group diffusion equation is an affordable option nowadays to compute …

The pin power reconstruction methodology for hexagonal geometry in the multigroup nodal
neutronics program Ants is described and verified against full core Serpent Monte Carlo …

The increasing deployment of renewable energy sources and greater electrification of
demand is requiring more frequent use of load following in pressurised water reactors …

This paper presents a substantial extension of the pin power reconstruction (PPR) method
used in the reactor dynamics code DYN3D with the aim to better describe the heterogeneity …
