BAW critical experiment benchmark analysis using PRAGMA GPU-based Monte Carlo code Open
This study validated the GPU-based continuous-energy Monte Carlo (MC) code PRAGMA under light water reactor (LWR) conditions using Babcock & Wilcox (BAW) critical experiment benchmarks. The benchmark calculation results with ENDF/B-VII.0, …

Neutron balance approach for inline critical rod position search calculation in Monte Carlo reactor analysis Open
The critical rod position search has been one of the issues in the Monte Carlo (MC) reactor analysis. This paper proposes a practical and simple approach for the critical rod position search based on the neutron balance equation and the mo…

Uncertainty quantification based on similarity analysis of reactor physics benchmark experiments for SFR using TRU metallic fuel Open
One of the issues in the development of the sodium-cooled fast reactor (SFR) using transuranic (TRU) metallic fuel is the absence of criticality benchmark experiment that faithfully mocks up the nuclear characteristics of the target design…

Design optimization of cylindrical burnable absorber inserted into annular fuel pellets for soluble-boron-free SMR Open
This paper presents a high performance burnable absorber named as CIMBA (Cylindrically Inserted and Mechanically Separated Burnable Absorber) for the soluble-boron-free SMR. The CIMBA is the cylindrical gadolinia inserted into the annular …

Dynamic rod worth measurement method based on eqilibrium -kinetics status Open
KHNP had licensed Dynamic Control rod Reactivity Measurement (DCRM) method using detector current signals of PWRs in 2006. The method has been applied to all PWRs in Korea for about 15 years successfully. However, the original method was i…
