ABSTRACT
A robust design is achieved by validating the basic design with numerical simulations and experimental verifications. Design of a fast reactor requires detailed studies on reactor physics, thermal hydraulics, and structural mechanics of core and assembly components. In this chapter, various concepts of core, along with methodology for calculating flux and power distributions, and various coefficients of reactivity are discussed. Also, the numerical simulation and experimental validation of problems associated with core thermal hydraulics and structural mechanics of core and assembly components in a sodium-cooled fast reactor (SFR) are brought out.
