nuclear power plants with pressure-tube reactors. SUBSTANCE: packing assembly is, essentially, set of W-shaped stacks with arc-shaped depressions and separators in-between. Each separator is made in the form of V-shaped flexible rings whose arc-shaped tops are located in arc-shaped depressions of W-shaped stacks and are brought in contact with them; separator blades elastically contact inner blades of W-shaped stacks; bottom supporting ring is provided with annular semi-tore projection contacting arc-shaped depression of bottom W-shaped stack; top supporting ring has annular groove to receive arc-shaped top of separator. EFFECT: improved tightness of joint between stacks and process channel surface. 4 cl, 3 dwg |
