Introduction The RAST-K 2.0 code is a recently developed three-dimensional two-group PWR core analysis code by UNIST CORE lab. It aims to be used by utilities to perform in-core fuel management studies, core design calculations, load follow simulation and transient analysis in neutronics. The RAST-K 2.0 code is capable of performing steady-state, quasi transient and transient calculations by solving the two-group three-dimensional neutron diffusion equation in eigenvalue or fixed source modes. Transverse Integrated Nodal Methods (TINMs) - Nodal Expansion Method (NEM) - Analytic Nodal Method (ANM) - Semi-analytic Nodal Method (SANM) Non-transverse Integrated Nodal Methods - Analytic Function Expansion Nadal (AFEN) Method - Polynomial Expansion Nodal (PEN) Method Unified Nodal Method - Integrate the NEM, ANM and AFEN into a single unified nodal formulation Verifications I.
