Abstract

The invention discloses a visual segmented sealing cylinder used for research on chemical effects in nuclear power plants, comprising a first connecting piece, a first transparent cylinder, a second transparent cylinder, and a second connecting piece sequentially connected, the first connecting piece, the second transparent cylinder, and the second connecting piece. Through holes are provided on the second connecting parts, the first connecting part is connected with the first transparent cylinder through a slot, and the second connecting part is connected with the second transparent cylinder through a slot; the first transparent cylinder, the second transparent cylinder are connected through a slot; The two transparent cylinders communicate with each other and are facing each other. The butt ends of the first transparent cylinder and the second transparent cylinder are provided with protruding protruding rings along the circumferential direction, and a filter layer and an annular sealing gasket are interposed between the two protruding rings. The ring-shaped sealing gasket is sleeved outside the filter layer, and the two protruding rings are detachably connected. The invention is used to solve the problem that there is no equipment suitable for the research of the chemical effect of the nuclear power plant in the prior art, and realizes the purpose of efficiently satisfying the research of the chemical effect of the nuclear power plant.

Description

technical field [0001] The invention relates to the field of nuclear power, in particular to a visual segmented sealing cylinder used for research on chemical effects of nuclear power plants. Background technique [0002] The pressurized water reactor nuclear power plant has set up a pit at the bottom of the containment, which is mainly used to collect the reactor coolant leaked from the reactor coolant system and the containment spray under the accident condition of the main pipe breach of the reactor coolant system in the containment System spray. In order to prevent sundries and debris in the containment from entering the safety system and the core with safety injection and spraying, causing performance degradation or damage to the safety system or components, and affecting long-term core cooling (LTCC), the containment pit is installed filter. [0003] After a LOCA accident in a nuclear power plant, the resulting debris may produce new chemical substances in the pit en...
