Effect analysis of ship motions on marine small modular reactor under full power operation condition   CHENG Kun1, MENG Tao1, LIU Zheng1, and TAN Sichao1   1. Fundamental Science on Nuclear Safety and Simulation Technology Laboratory, Harbin Engineering University, Harbin 150001, China ( chengkunhrbeu@sina.com; tansichao@hrbeu.edu.cn )   Abstract:Marine Small Modular Reactor (M-SMR) can effectively solve the offshore energy supply problem in marine resource development and island construction. Affected by ocean waves or other ocean conditions, the M-SMR can generate different kinds of ship motions, which can oscillate the thermal hydraulic parameters and threaten the reactor safety. Through adding ocean condition calculation module into the RELAP5 code, a reactor thermal-hydraulic system analysis code for M-SMR is developed. Effects of three typical ship motions (inclination, heaving and rolling) on the full power operation of a two-looped M-SMR is calculated. Results show M-SMR can keep safety operation under all assumed ocean conditions in present work. Heaving and rolling can cause the flow rate oscillation in both primary and secondary loops.
