FIELD: physics. SUBSTANCE: invention relates to heat engineering, particularly to NPP equipment, and concerns thermal insulation and radiation protection of pipelines implemented simultaneously. Block quick-detachable protection of NPP pipelines includes heat-insulated blocks secured by locks located on pipeline surface. Blocks consist of external and internal boxes filled with heat-insulating material. Inner box is smaller in size and fitted in outer box. On external surface of boxes there is radiation-protective screen, protective wall from two halves with hinge and with threaded pair consisting of pin and nuts. Joints of boxes with heat-insulating material are stepped. EFFECT: technical result consists in combination of functions of heat insulation and radiation protection in one device and in increase in efficiency of thermal insulation.
