“…The Japan Atomic Energy Agency (JAEA) has investigated an 800 MW LBE-cooled subcritical reactor with a 1.5 GeV proton accelerator to transmute minor actinides [7]. Research on a hybrid power extraction reactor (HYPER) was carried out by the Korea Atomic Energy Research Institute (KAERI) to produce energy and transmute nuclear waste [8]. The China lead-based reactor (CLEAR) and the Chinese initiative accelerator driven subcritical system (CiADS) have been proposed by the Chinese Academy of Sciences for the transmutation of nuclear waste and sustainability of nuclear energy development [9,10].…”

The accelerator driven subcritical system (ADS) has been chosen as one of the best candidates for Generation IV nuclear energy systems which could not only produce clean energy but also incinerate nuclear waste. The transient characteristics and operation principles of ADS are significantly different from those of the critical nuclear energy system (CNES). In this work, the safety characteristics of ADS are analyzed and compared with CNES by a developed neutronics and thermal-hydraulics coupled code named ARTAP. Three typical accidents are carried out in both ADS and CNES, including reactivity insertion, loss of flow, and loss of heat sink. The comparison results show that the power and the temperatures of fuel, cladding, and coolant of the CNES reactor are much higher than those of the ADS reactor during the reactivity insertion accident, which means ADS has a better safety advantage than CNES. However, due to the subcriticality of the ADS core and its low sensitivity to negative reactivity feedback, the simulation results indicate that the inherent safety characteristics of CNES are better than those of ADS under loss of flow accident, and the protection system of ADS would be quickly activated to achieve an emergency shutdown after the accident occurs. For the loss of heat sink, it is found that the peak temperatures of the cladding in the ADS and CNES reactors are lower than the safety limit, which imply these two reactors have good safety performance against loss of heat sink accidents.

“…Firstly, uranium-lean (as much as U-50 wt.% Zr) compositions are found in the center region of high burnup U-10 wt.% Zr fuel rods. Secondly, uranium-lean and zirconium-rich U-Zr alloys are considered for advanced nuclear reactors such as the Korean subcritical Hybrid Power Extraction Reactor (HYPER) [12]. U-Zr alloy microstructure and metallurgical behavior are critical for fuel performance codes, fabrication, and core design.…”

“…The longterm radiotoxic inventory of geological repositories can be reduced by a factor of 100 if the MAs are fully recycled and incinerated (Salvatores and Palmiotti, 2011). Fast spectrum systems are required to incinerate the MAs, but the introduction of MAs will lead to significant reduction of Doppler coefficient, increasing in positive coolant void worth and smaller effective delayed neutron R&D on the accelerator driven system called HYPER (Hybrid Power Extraction Reactor) (Park et al, 2000a(Park et al, , 2002b. In 1999, a road map for developing accelerator transmutation of waste (ATW) technology was proposed in the USA (DOE, 1999), and then the ATW program was replaced by Advanced Accelerator Application (AAA) program in 2001.…”
