A viewing window suitable for nuclear power plant containment and its application method

Abstract

The invention discloses a viewing window suitable for nuclear power plant containment and an application method thereof, belonging to the technical field of nuclear power plants, comprising: an outer frame, two ends of which are respectively provided with a first opening connected to the inside of the containment and a first opening connected to the outside of the containment The second opening; a glass assembly, installed in the outer frame near the first opening side, including pressure-bearing lead glass, a first concave lens, a second concave lens, and a convex lens; a shielding cover plate assembly, installed in the outer frame near the second opening side, including The shielding enclosure, the first shielding material filled in the shielding enclosure, the rotating handle penetrating through the shielding enclosure, and the hinge mechanism installed outside the shielding enclosure, the shielding enclosure is connected to the outer frame through the hinge mechanism, and the shielding enclosure is installed on the outside After being inside the frame, the limit between the shielding panel and the outer frame can be realized by rotating the handle. The beneficial effect of the invention is that the viewing angle is enlarged, and it is convenient for the staff to observe the situation inside the reactor more intuitively, and at the same time, the pressure of the containment and the integrity of the shielding boundary are ensured.

Description

technical field [0001] The invention relates to the technical field of nuclear power plants, in particular to a viewing window suitable for a containment shell of a nuclear power plant and an application method thereof. Background technique [0002] The nuclear power plant reactor containment viewing window is a see-through device for nuclear power related staff to observe the state inside the nuclear power plant containment. [0003] Since the temperature, pressure and irradiation environment in the reactor containment are not suitable for the staff to enter the inspection during the daily inspection of the reactor, setting a viewing window on the containment can facilitate the staff to understand the situation in the reactor intuitively and clearly, and assist the failure Judgment matters. [0004] The existing viewing windows of nuclear power plants use lead glass to realize the functions of seeing through and shielding. The lead glass has many disadvantages such as high...

Problems solved by technology

[0004] The existing viewing windows of nuclear power plants use lead glass to realize the functions of seeing through and shielding. The lead glass has many disadvantages such as high density, poor light transmission, and thick thickness, which leads to the small viewing angle of the existing viewing windows.
