REACTOR ROOM CONTAINMENT Russian patent published in 2001 - IPC

FIELD: construction engineering; construction of pre-stressed reinforced containments. SUBSTANCE: horizontal and vertical channels for pre-stressed flexible members are arranged as close as possible to external surface of containment wall; anchors are made in the form of bidentate fork and arranged in tiers across containment wall so that short parts of fork envelop horizontal channels and long parts are fastened to internal surface of containment wall. Pre-stressed flexible members are less exposed to temperature difference; concrete portions that have not been pre-stressed earlier are placed in operation. EFFECT: provision for eliminating areas of concrete riving when flexible member suffers stresses. 4 dwg
