“…The IFR concept offers an opportunity for the BOP to establish a newly built strategy that would deliver significant cost savings. Combined with favorable reactivity feedback properties of the metallic fuel, broad thermal inertia related to the sodium pool develop the reactor system to prevent different transients originating from the BOP [22]. The IFR concept also provides a dramatic decrease in fuel cycle cost as associated with the traditional Purex-based oxide fuel cycle.…”

In this paper, the advancement of the integral fast reactor (IFR) is studied. We proposed the safety passive inherent approach which keeps the IFR operations safe from the maintenance cost. Additionally, it is observed that when failure appears in the reactor then safety passive inherent works efficiently and it turns off the reactor to preserve the safety. Therefore, it is necessary to use the inherent properties of the metallic fuel such as liquid metal, and it should be cooled in a way to substantial developments in the total appearances of the reactor system. Moreover, the key advantages of the IFR concept are narrated briefly with its mechanic position and the future development and research directions.

“…In most designs, dampers are used to limit the air intake through the AHX during normal operation so that parasitic heat losses to the environment are minimized during power generation. Advanced design concepts exist which incorporate fluidic diodes to minimize primary coolant flow rates during normal operation (Zhao, Zhang, Mousseau, & Peterson, 2009), which can be used in place of or in combination with dampers to minimize parasitic heat losses during normal operation of the plant. These concepts can either be pool-type or hybrid pool-type, depending on the specific design.…”

“…Because the DHXs cool the primary coolant directly, they can be sized accordingly without regard to the surface area to volume ratio of the reactor. Although different configuration concepts exist, currently the dominant focus for the FHR is on hybrid pool-type concepts (Zhao, Zhang, Mousseau, & Peterson, 2009), so the DRACS has been selected as one of its passive heat removal mechanisms. Given the flow direction reversal that occurs in postulated FHR accidents of interest to the DRACS, a "directional" DHX is proposed in this paper.…”

The use of Direct Reactor Auxiliary Cooling Systems (DRACS) as a safety-related decay heat removal system for advanced reactors has developed historically through the Sodium Fast Reactor (SFR) community. Beginning with the EBR-II, DRACS have been utilized in a large number of past and current SFR designs. More recently, the DRACS has been adopted for Fluoride salt-cooled High-temperature Reactors (FHRs) for similar decay heat removal functions. In this paper we introduce a novel directionally enhanced DRACS heat exchanger (DHX) concept. We present design options for optimizing such a heat exchanger so that shellside heat transfer is enhanced in one primary coolant flow direction and degraded in the opposite coolant flow direction. A reduced-scale experiment investigating the hydrodynamics of a directionally enhanced DHX was built and the data collected is presented. The concept of thermal diodicity is expanded to heat exchanger technologies and used as performance criteria for evaluating design options. A heat exchanger that can perform as such would be advantageous for use in advanced reactor concepts where primary coolant flow reversal is expected during Loss-Of-Forced-Circulation (LOFC) accidents where the ability to circulate coolant is compromised. The design could also find potential use in certain advanced Sodium Fast Reactor (SFR) designs utilizing fluidic diode concepts.
