Analysis of a sustainable gas cooled fast breeder reactor concept

Linear regression and sensitivity analysis in nuclear reactor design

“…To obtain a controlled nuclear fission chain reaction with breeding capability the following objectives need to be met: higher value for T f;f , and k 1 > 1. The parameters analyzed in the fuel pin cell module are, the radius of the fuel pin in the fuel element (r f ), and the enrichment of U-233 in Th-U fuel (Kumar et al, 2014). It is to be noted that, T f;f depends on the p D ratio.…”

“…However, for simplicity, the control rods, and the axial blankets have been ignored in the design. A detailed description of other components are presented in the paper (Kumar et al, 2014). The core consists of an array of hexagonal assemblies wherein, an assembly consists of an array of fuel elements in a hexagonal lattice.…”

“…For the whole core analysis, the configuration of the core of an existing gas cooled fast breeder reactor design (Kumar et al, 2014) has been used. However, for simplicity, the control rods, and the axial blankets have been ignored in the design.…”

“…The model of a gas cooled fast breeder reactor (GCFBR) design (Kumar et al, 2014) is used to perform the SA, and LR analysis. The system consists of a, heterogeneous neutronics model for criticality, and flux calculations, basic thermal hydraulics calculation for transfer of heat from the fuel pin to the coolant, and energy transfer using the Brayton's cycle.…”

Optimization of U–Th fuel in heavy water moderated thermal breeder reactors using multivariate regression analysis and genetic algorithms

“…Analysis of the core parameters, also known as ''parametric core analysis'' has not been explored to a satisfactory level, however Perry and Weinberg (1972) and Taraknath and Ricci (2013) have done appreciable research in understanding the behavior of core parameters, and presenting their significance in reactor design. Perry and Weinberg (1972) performed the, reactor physics calculations, and analysis of behavior of reactor parameters in thermal breeder reactors, those include fluid fuel-thermal breeders such as aqueous-slurry systems and molten salt systems, and solid fuel-thermal breeders such as heavy water reactors, gas cooled reactors (Kumar et al, 2014), and light water reactors. Taraknath and Ricci (2013) focuses on PHWR core parameter analysis of PHWR reactors design using thorium based fuel.…”
