DISINTEGRATOR-PUMP Russian patent published in 2001 - IPC

FIELD: tritium water separating equipment. SUBSTANCE: disintegrator-pump has casing with inlet and outlet branch pipes, rotor positioned axially of casing and provided with openings made in cylindrical surface. Rotor is communicated via annular channel with casing openings. Cavity defined between casing and rotor surface is isolated from inlet and outlet branch pipes and communicated via branch pipe with heavy and superheavy water collectors. Perforated rings are positioned between cavity and annular channel on rotor cylindrical surface. Ring opening axes are positioned so that inner ring is offset relative to sequence of rings. Disintegrator-pump bypasses main circuit of basic circulation pump. Disintegrator-pump is employed in circulation systems of atomic power stations using water-cooled power reactors for obtaining heavy and superheavy water from normal water and using it in atomic power engineering. Disintegrator-pump of such construction allows neutron absorption by oxygen and hydrogen of normal water to be eliminated and heavy water and superheavy water mixture to be used in the future in water-cooled power reactors. It allows costs to be reduced by eliminating excessive expenses for fuel. EFFECT: increased efficiency and wider operational capabilities. 1 dwg
