The feasibility of the dual cooled annular fuel rod with coated burnable absorber in the
hexagonal assembly of the VVER-1000 reactor was studied. The models consist of a 4.5 …

This research discusses the neutronic characteristics of VVER-1200 assembly fueled with
five different fuel types based on thorium. These types of fuel based on mixing thorium as a …

In this study, the mechanisms that cause heat split, a specific phenomenon in dual-cooled
annular fuel elements, were investigated. On the basis of thermal resistance analysis, the …

One of the approaches which can help the enhancement of a reactor power is changing its
fuel geometry. For this purpose, as well as decreasing the maximum fuel temperature in …

Modeling and burnup analysis of Uranium dioxide (UO 2) and Mixed Oxide (MOX) fuel in
square assemblies comprising both solid and annular rods was carried out. The lattice pitch …

The critical heat flux (CHF) is an important thermal–hydraulic parameter that must be
determined during the design of water-cooled reactors to ensure safety of operation. In this …

In this paper, a thermal–hydraulic analysis of nanofluid as the coolant is performed in a
typical VVER-1000 reactor with internally and externally cooled annular fuel. The fuel …

Stemming from a renewed interest in the suitability of thorium as fertile isotope, this study
presents an extensive survey of some of the recent advances on the use of thorium in light …

The impacts of moderation on the neutronic behavior of the VVER-1000 reactor assembly
have been investigated by using annular fuel and compared with the conventional one. The …

Nowadays, many efforts have been made to improve the efficiency of nuclear power plants.
One of which is use of the dual cooled annular fuel which is an internally and externally …
