A preliminary design study for the HYPER system

Mass transfer of iron impurities in LBE loops under non-isothermal flow conditions

“…Recently, LBE gained renewed interest in nuclear applications such as accelerator driven systems (ADS) [1][2][3][4][5][6]. The corrosion of the structural materials mainly steels is a great concern particularly the dissolution of their base and alloying elements [4,[7][8][9][10] leading to coolant contamination but more deleterious to the structural integrity.…”

Preliminary studies of a new accelerator-driven minor actinide burner in industrial scale

“…This kind of metal matrix can remain the continuous metal phase with negligible damages from the fission products. It is beneficial for the fuels to withstand higher burnup without significant swelling (Yang and Khalil, 2001a;Park et al, 2002b).…”

“…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.…”

Studies on LLFP transmutation in a pressurized water reactor

“…Park et al studied the LLFP transmutation target assembly design in the HYPER system. They concluded that the assembly configuration where 99 Tc is loaded as a plate type in the outermost region and 129 I is loaded as NaI rods with CaH 2 in the inner region might achieve the best transmutation performance [20]. Kim et al concluded that the homogeneous mixture shows the best performance due to the minimized target nuclide self-shielding effect [16].…”
