Coupling of the thermal-hydraulic and neutronic calculations for bwrs
202011 ÖZET Kaynar Su Reaktörlerde termal-hidrolik ve nötronik hesaplar arasında kuvvetli bir bağlaşım bulunur. Bir Kaynar Su Reaktörüne bu bağlaşım hesaplarını uygulamak için COBRA-IV bilgisayar kodu alt-kanal analizinde, WIMS-D/4 kodu makroskopik etkin tesir kesiti hesaplarında ve CITATION kodu asemble ve kor güç hesaplarında kullanılmıştır.

Liquid-Metal-Cooled Reactor Thermal-Hydraulic Calculations in the United States
Nuclear Science and Engineering, 1988A wide range of thermal-hydraulic computer codes has been developed by various organizations in the United States. These codes cover an extensive range of purposes from within-assembly-wise pin temperature calculations to plantwide transient analysis. The codes are used for static analysis, analysis of protected anticipated transients, and analysis of ...

Description of a stable scheme for steady-state coupled Monte Carlo–thermal–hydraulic calculations
Annals of Nuclear Energy, 2014Abstract We provide a detailed description of a numerically stable and efficient coupling scheme for steady-state Monte Carlo neutronic calculations with thermal–hydraulic feedback. While we have previously derived and published the stochastic approximation based method for coupling the Monte Carlo criticality and thermal–hydraulic calculations, its ...

Annals of Nuclear Energy, 2013
Numerically stable Monte Carlo burnup calculations of nuclear fuel cycles are now possible with the previously derived Stochastic Implicit Euler method based coupling scheme. In this paper, we show that this scheme can be easily extended to include the thermal–hydraulic feedback during the Monte Carlo burnup simulations, while preserving its ...

Influence of Thermal-Hydraulic Model to Fuel Management Core Calculation
2008The integration of neutronic, fuel rod and thermal-hydraulic calculations for both, steady-state core design type of the calculation and for transient and safety analyses, is used to improve the response of Nuclear Power Plants (NPP) both from the point of view of safe and economic plant operation.

Volume 6: Thermal-Hydraulics and Safety Analysis
Abstract Due to the strong feedback effect between neutronics and thermal-hydraulics in the core of pressurized water reactors (PWR), neutronics and thermal-hydraulics coupling calculations are often used in the design and safety evaluation of PWR to provide more accurate results.
