The report contains a brief history of the superconductor’s researches and their applications carried out in the Institute for Low Temperature Physics and Engineering (ILTPE) of the National Academy of Sciences of Ukraine since the ILTPE foundation in 1960. The most important results of the researches in the field of the low- and high-temperature superconductors (HTS) are stated more detailed. The experimental validation of an electromagnetic radiation of Josephson junctions; the electron pairing and existence of the distant order in the HTS; a creation of the superconducting quantum interference devices (SQUIDs) on the basis of the HTS; formation and moving of the local frozen magnetic field along the surface of the HTS; the transport properties of new Fe-based superconductors can be referred to such results.

PRHR system for low temperature and low pressure pool-type LWR, AHR400 is designed by two-phase closed thermosyphon and experimental validation is conducted. AHR400 is dedicated only to heat generation used in seawater desalination and operation temperature and pressure. LBLOCA is not considered as DBA due to no pipeline in primary system. There are LOHS and SBO for DBAs and PRHR system reduces damage during DBAs. Design of the PRHR system follows Direct Reactor Auxiliary Cooling System (DRACS) type. Two-phase closed thermosyphon, which uses phase change of working fluid, is applied to the PRHR system and the heat transfer in thermosyphon are analyzed by thermal resistance calculation model. Experimental thermosyphon that has similar thermal condition with the thermosyphon in designed PRHR system was explored for validation. The results show that the evaporation model overestimates heat transfer rate on the evaporator region.
