Steam generator is the most key equipment in sodium cooled fast reactor, and it is also one of the most prone to safety problems. In order to improve the safety and economy of steam generator, many innovative steam generator schemes have been put forward on the basis of traditional schemes in the countries with fast development of sodium cooled fast reactor technology. In this paper, various innovative schemes are studied, the main characteristics of each scheme are discussed, the main direction and development trend of improvement are summarized, and the key technologies to be solved in the research of new type steam generator are given. The results of this paper can provide help and guidance for the future research of new steam generator for sodium cooled fast reactor.
