A Thermohydraulic Code for Low Temperature Nuclear Heating Reactor and Its Passive Residual Heat Removal Systems

Passive Decay Heat Removal for the Advanced High Temperature Reactor

This report presents a design concept for a high-capacity decay-heat removal system for the molten-salt cooled Advanced High Temperature Reactor (AHTR) [1]. The design is closely derived from the General Electric S-PRISM reactor, which is a sodium pooltype reactor [2]. The AHTR is distinguished from the S-PRISM by its use of a hightemperature thermal blanket, shown in Fig.1, that allows the ves...

Performances of Low Temperature Radiant Heating Systems

The low temperature radiant systems are very complex because they involve different mechanisms of heat transfer: heat conduction through the walls, heat convection between the heating panel and the indoor air, heat radiation between the heating panel and the surrounding areas, and the heat conduction between the floor and the ground. The main essence of the low-temperature air systems is to pro...

In-containment Refueling Water Storage Tank (IRWST): In-containment passive long-term recirculation means Passive Residual Heat Removal (PRHR) utilizing Passive Residual Heat Removal Heat Exchanger (PRHR HX): Automatic Depressurization System (ADS): Internal IEs: Three major types of IEs

Safety of a nuclear power plant and its related systems are the first key issue to assure experts and the public of the safe operation of the plant. The AP1000 reactor is provided with passive safety systems which require no operator actions due to utilizing only natural forces such as gravity, natural circulation and compressed gas to achieve the safety function. In this paper the core damage ...

Passive Energy Air-to-Water Heat Pipe Based Heat Exchanger and its Potential of Air Pre-cooling in Air Conditioning Systems for Iran Climate

Air pre-cooling equipment is normally being employed in air-conditioning systems for pre-cooling the ambient outdoor air to enhance the air-conditioning systems performance. In this study, the potential of a passive water-to-air heat pipe based heat exchanger (HPHEX) for air pre-cooling purpose in air-conditioning systems for the high cooling load demanding regions of Iran was investigated. To ...
