The objective of the study presented is to reserve the basis for the design and construction of a 10MWt NDHR in KAERI site after surveying and analyzing the development status and the technical data for the NDHR under operation and development in the world. The results of the study are that the verification tests of the performance and the safety for the components and systems composing the reactor are required because the NDHR, for the most part, are under development stage except some reactors. Concerning with the design and construction of a NDHR in Korea, it seems to be desirable that the selection of the reactor and the co-work with a foreign country should be performed after reviewing the technical characteristics, safety, economy and the possibility of domestic production of NDHR in depth. Additionally as the regulation and licensing for the NDHR are not established yet except for some countries, it is required that the work concerning with the regulation and licensing should be performed at the sometime.
