ABSTRACT
We present recently developed new concepts for ocean nuclear power plants (ONPPs)using gravity-based structures (GBS) and tension leg platforms (TLP) [1-3]. For GBStype ONPPs, the large nuclear reactor (APR 1400) and the small and medium nuclearreactor (SMART) are mounted, respectively. For a TLP-type ONPP, SMART ismounted. We introduce basic design concepts including new general arrangements(GAs) obtained through a modularization method. In order to evaluate their safety andstability, a fully coupled seismic analysis considering GBS-seawater-soil interaction is performed for GBS-type ONPP. Hydrostatic and dynamic analyses are conducted forthe TLP-type ONPP. We believe that ONPPs are the next generation nuclear powerplants with enhanced safety useful for mankind.
