New burnup calculation system for fusion–fission hybrid reactor

Speed-up of cross-section collapsing with weight-window for subcritical burnup calculation

“…The bunrup calculation was performed repeating the following steps: [8](1) criticality check (KCODE option of MCNP), (2) transport calculation (MCNP), (3) reaction rate estimation (original post-process code) and (4) burnup calculation (ORIGEN).…”

“…So far, the calculation system has been modified continuously to improve the transport and reaction rate calculation accuracy and the calculation speed [8,9]. The most important improvement is to use track-length (TL) data directly, which are created internally in MCNP and utilized as base information of neutron flux to carry out the reaction rate estimation for burnup.…”

A fusion–fission hybrid reactor with water-cooled pressure tube blanket for energy production

“…It was proved that an ITER-type tokamak is feasible to be used as a neutron source for energy production (Murata et al, 2005(Murata et al, , 2007Zhou et al, 2011). The possibility that an ITER-type tokamak neutron source could be used for the transmutation of SNF was also investigated at Georgia Tech (Stacey, 2007(Stacey, , 2009.…”

The neutronics studies of a fusion fission hybrid reactor using pressure tube blankets

“…The reprocessed plutonium in the matrix of depleted uranium is used as the fuel. It is indicated that such a selection is suitable for energy producing [4]. Also the Th-U fuel cycle was evaluated in the further studies [5,6].…”
