N2 - An SCLWR-H core is designed with 3-D coupled thermo-neutronic core calculations for the first time. The change in power distribution is reflected to the evaluation of water density distribution in the core. The thermal-hydraulic and neutronic calculations are alternatively carried out until convergence is obtained. In the 3-D core calculation, each fuel assembly is modeled and the burnup, power and temperature distributions are evaluated. Fuel enrichment, burnable poisons, reload pattern, control rod pattern and the coolant flow rate distribution are designed to give average core outlet temperature 500C.
