 Aiming at the realization of the nuclear heat application system with a High Temperature Gas-cooled
Reactor (HTGR), research and development on the whole evaluation of the system, the connection
technology between the HTGR and a chemical plant such as the safety evaluation against the fire andexplosion and the control technology, and the vessel cooling system of the HTGR were carried out.
 In the whole evaluation of the nuclear heat application system, an ammonia production system using
nuclear heat was examined, and the technical subjects caused by the connection of the chemical plant to the
HTGR were distilled. After distilling the subjects, the safety evaluation method against the fire andexplosion to the reactor, the mitigation technology of thermal disturbance to the reactor, and the reactor corecooling by the vessel cooling system were discussed. These subjects are very important in terms of safety.
About the fire and explosion, the safety evaluation method was established by developing the process andthe numerical analysis code system. About the mitigation technology of the thermal disturbance, it wasdemonstrated that the steam generator, which was installed at the downstream of the chemical reactor in thechemical plant, could mitigate the thermal disturbance to the reactor. In order to enhance the safety of thereactor in accidents, the heat transfer characteristic of the passive indirect core cooling system wasinvestigated, and the heat transfer equation considering both thermal radiation and natural convection wasdeveloped for the system design.
 As a result, some technical subjects related to safety in the nuclear heat application system were solved.
