3D modeling of the primary circuit in the reactor pressure vessel of a PHWR
(Elsevier Science Sa, 2013-12)
A computational fluid dynamics (CFD) simulation of the reactor pressure vessel (RPV) of the pressurized heavy water reactor (PHWR) of 745 electrical MW Atucha II nuclear power plant was carried out. A three dimensional ...
A Coupled Model for Two-Phase Simulation of a Heavy Water Pressure Vessel Reactor
(World Academy of Science, Engineering and Technology-WASET, 2015-11)
A Multi-dimensional computational fluid dynamics(CFD) two-phase model was developed with the aim to simulatethe in-core coolant circuit of a pressurized heavy water reactor(PHWR) of a commercial nuclear power plant (NPP). ...
Negative power coefficient on PHWRs with CARA fuel
(Elsevier Science, 2014-02)
A study of power coefficient of reactivity in heavy water reactors is made analyzing the reactivity components of fuels with several modifications oriented at reducing the coefficient. A cell model is used for neutronics ...
CFD model of a moderator tank for a pressure vessel PHWR nuclear power plant
(Pergamon-Elsevier Science Ltd, 2016-08)
The CFD thermal hydraulic simulation of a Pressurized Heavy Water Reactor (PHWR) moderator tank was performed. Heating was achieved by considering two heat sources, conduction/convection through the coolant channels and ...
Assessment of nuclear power reactor using computational fluid dynamics
(2015-03-25)
Computational methods have been used in safety and design analysis of reactor systems for nearly 40 years. The most popular computational fluid dynamics codes have been formulated based on 0/1D methods. Although the flow ...
Effect of lead factors on the embrittlement of RPV SA-508 cl 3 steel
(Elsevier Science, 2013-03)
This paper presents a project to study the effect of lead factors on the mechanical behaviour of the SA-508 type 3 Reactor Pressure Vessel (RPV) steel used in the reactor under construction Atucha II in Argentina. Charpy-V ...
