NUCLEAR REACTOR ATTACHMENT POINT Russian patent published in 2009 - IPC G21C13/24 

FIELD: power engineering.

SUBSTANCE: invention refers to nuclear engineering and namely to nuclear power stations with shell-type reactors, and deals with fixing a nuclear reactor shell in the vault. Nuclear reactor shell attachment point consists of a support ring, keys, hold-down straps and pins. A base ring is located on the support truss of reactor vault and connected to the support truss. On that ring there coaxially located is the support ring. There is a flange in the lower part of the latter. Flange overlaps the base ring along outside diametre and across the height. In the base and support rings the slots are made from inside diametre. In those slots there located are wedges with through threaded holes. Lower plane of wedges is sloped in the direction of the hole made in the support truss under reactor shell, and upper plane thereof interacts with the support ring and is horizontal and parallel to the support truss plane. In the support ring there made are through holes in the slots for wedges. Adjusting bolts are passed through those holes and screwed in threaded holes of wedges.

EFFECT: simplifying design of nuclear reactor attachment point and improving attachment reliability of nuclear reactor.
