FIELD: nuclear power engineering. SUBSTANCE: reactor has evacuated vessel, blanket segments with fastenings, and supporting structure. The latter is provided with longitudinal ribs with slots made throughout their entire width to receive projections made on side walls of segments with slits provided over their length to receive latches placed on side walls of segments for rotation. Supporting structure is installed for displacement in radial direction relative to vessel. Threaded hole is made in rib from end to slit; latch is mounted on shaft provided with castellated nut with outer thread placed in threaded hole. Rotating latch is keyed on shaft for displacement from shaft axis. Made in slit wall on vessel side is horizontal depression whose length equals rib width and its width corresponds to that of latch. EFFECT: provision for compensating for temperature expansion of blanket, vessel, supporting structure; provision for compensating thrusts in blanket due to plasma breakup thereby improving reactor reliability and service life; provision for replacing faulty blanket segments by new ones. |
