This paper presents the validation of UNIST in-house Monte Carlo code MCS used for the high-fidelitysimulation of commercial pressurized water reactors (PWRs). Its focus is on the accurate, spatiallydetailed neutronic analyses of startup physics tests for the initial core of the Watts Bar Nuclear 1 reactor,which is a vital step in evaluating core phenomena in an operating nuclear power reactor. The MCSsolutions for the Consortium for Advanced Simulation of Light Water Reactors (CASL) Virtual Environmentfor Reactor Applications (VERA) core physics benchmark progression problems 1 to 5 were verifiedwith KENO-VI and Serpent 2 solutions for geometries ranging from a single-pin cell to a full core. MCSwas also validated by comparing with results of reactor zero-power physics tests in a full-core simulation. MCS exhibits an excellent consistency against the measured data with a bias of ±3 pcm at the initialcriticality whole-core problem. Furthermore, MCS solutions for rod worth are consistent with measureddata, and reasonable agreement is obtained for the isothermal temperature coefficient and soluble boronworth. This favorable comparison with measured parameters exhibited by MCS continues to broaden itsvalidation basis. These results provide confidence in MCS's capability in high-fidelity calculations forpractical PWR cores.
