FIELD: nuclear engineering.
SUBSTANCE: invention relates to nuclear reactor control and protection system, and can be used in guide sleeves of nuclear reactor shielding and control member (SCM) and tools for installation, fixation and extraction of sleeves. SCM guide sleeve comprises case to accommodate control member, element for passage and location of mounting tool and cylindrical shank, which are permanently connected to each other. Upper part of element for passage and location of mounting tool is made with bayonet slots to make upper bayonet assembly with mating projections of mounting tool. Shank is equipped with bayonet sleeve and spring-loaded rod. Bayonet sleeve is provided with bayonet slots to make lower bayonet assembly with mating projections of pressure manifold bushing. Installation tool comprises head for gripping of overload mechanism and shank with ledges.
EFFECT: simplified mounting-dismantling operations.
