This reactor has many Blocks of Metal-Fuel (U-Pu-10%Zr) piled as Fuel-core. So the Fuel-core involves no metallic structure, the Fuel-core has high density of heavy-metal (7336kg/m3 ) in spite of having enough space of cooling channel, and is enclosed by the reflectors so that this reactor has high Plutonium-breeding capacity. The breed-burn wave goes down from upper burning blocks to lower blanket-blocks like Traveling Wave Reactor. When the top burning block goes over burn-up limit (7%), this block is removed from the reactor with no shutdown times, and the blanket-blocks are supplied every 2 years so that the breed-burn wave keeps stable. The blanket-blocks are made of recycled LWR-used fuel so that the Nuclear Fuel Cycle works effectively.
