FIELD: nuclear power engineering. SUBSTANCE: installation has L-shaped spatial frame built up of modules and provided with movable cavity that houses turning gear wheel and turret with rams, and laser plant. Telephoto lenses and ultrasonic cavity-position metering devices are mounted outside. Frame is mounted on castors contacting bearers. Stepping motors are used to set movable cavity as well as gear wheel and turret in rotary, upward, and downward motion. Rams are equipped with scanning devices incorporating ultrasonic measuring devices. EFFECT: improved design. 2 cl, 6 dwg
