Critical power experiments using the test section with an axially uniformly-heated tight-lattice rod bundle have been carried out. One of the aims of the experiments is to propose the critical power correlation. Critical power in tight-lattice rod bundles is very important on the thermal-hydraulic design of the Reduced-Moderation Water Reactor (RMWR). Many parameter effects on critical power such as flow and configuration parameters, axial and radial power distributions, bundle size etc. have to be considered. In this investigation, we focused on the fundamental parameter effects such as flow and configuration parameter and radial power distribution on critical power as the first step. Test section was an axially uniformly-heated 7-rod bundle with gap between rods of 1.0 mm, rod diameter of 12.3mm and heated length of 1.8m. Critical power correlation for the axially uniformly-heated tight rod bundles was derived based on the present and BAPL databases. An excellent agreement was obtained between the developed correlation and data (371 points) within an error of ±4.6%.
