PROTECTING DEVICE OF THE NUCLEAR POWER PLANTS AND METHOD OF DECREASING PRESSURE IN ADJACENT BUILDINGS OF THE NUCLEAR POWER PLANT

摘要

The protective device of the nuclear power plant (4) in the form of the building surrounding the nuclear power plant (4), the inner wall (2) of which consist of thermally resistant material and is fixed on the specialised construction, whilst the inner wall (2) is equipped with the outlets that can be closed with the closing devices (8), for example by clappers, which can be open outwards, particularly under the pressure effect. The outlets on the inner wall (2) made by massive metal plates of the chamber nose (6, 7), placed between outer and inner walls, in which the filtration device (9) for the finest grains with exchangeable fillers for radionuclides filtration is placed and which comes to the annular space between the outer and inner walls (2), which creates the mixing space connected with the outer space by untightnesses of the outer cover (32).
