REACTOR COMPARTMENT OF ATOMIC POWER STATION Russian patent published in 1995 - IPC

FIELD: atomic power engineering. SUBSTANCE: reactor jacket of atomic power station includes protective shell 3 composed of two layers 5 and 6 placed coaxially. Internal rooms 1 with technological equipment are mounted on platform 21 which rests against baseplate 20 through system of seismic insulation manufactured in the form of rocking supports 22, for instance. System of seismic insulation is supplemented with dampers 24. Protective shell lies on supports 27 mounted for movement over baseplate in radial direction. Internal space of shell communicates with transportation tunnel 29 through hatches. Hatches in layers of protective shell 3 are made along axis of their bottoms and are provided with lifting covers 18 and 19. Hermetic lock is located between covers. Manufacture of protective shell from two layers and positioning of lock in zone of least stresses makes it possible to increase reliability of reactor compartment of atomic power station. EFFECT: increased reliability of reactor compartment of atomic power station. 3 dwg
