【Abstract】 The research and development status of Primary Heat Exchanger (PHE) for nuclear heating reactor are described. On the base of PHE of Daqing 200 MW Nuclear Heating Reactor, Continuous fins are applied outside the U tubes, which highly increase the heat transfer coefficient. As a result, compact and enhanced PHE are designed.更多还原
