Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but these embodiments should not be construed as limiting the present invention.

[0025] In order to reduce the adjustment of the nuclear process system as much as possible and keep the construction scale of the underground cavern within the current construction technology level of the underground cavern, the simplest way to build an underground nuclear power plant is to use the reactor building as the core of the nuclear island in the existing ground nuclear power plant. The center is stretched in the radial direction, and each factory building is arranged in different small caverns, thus presenting the characteristics of a circular arrangement as a whole. In this way, 6 independent underground caverns need to be built, including the reactor building cavern, the fuel plant cavern, the safety plant cavern, the nuclear auxiliary plant ca...

Abstract

The invention discloses an underground nuclear plant with nuclear island cavern groups distributed in an L shape. The underground nuclear plant comprises nuclear islands used for generating steam through nuclear fission energy and arranged in underground cavern groups, a reactor factory building cavern used for containing reactor factory buildings is arranged in the middle in the underground cavern groups, and auxiliary cavern groups used for containing auxiliary factory buildings are arranged around the reactor factory building cavern in an L shape. By means of the underground nuclear plant with the nuclear island cavern groups distributed in the L shape, an existing underground cavern digging technology meets the building requirement of the underground nuclear plant, the number of caverns contained in the auxiliary cavern groups is small, and stability of surrounding rock is facilitated.

Description

technical field [0001] The invention relates to underground nuclear power technology, in particular to an underground nuclear power plant with an L-shaped arrangement of caverns on a nuclear island. Background technique [0002] The Chernobyl nuclear accident in the former Soviet Union, the Three Mile Island nuclear accident in the United States, and the Fukushima nuclear accident in Japan have shown that the existing ground nuclear power plants are not enough to effectively prevent and control nuclear leakage and ensure nuclear safety under extreme accident conditions. For this reason, some scholars and research institutions at home and abroad have proposed to build large-scale commercial nuclear power plants underground and use the natural shielding effect of rock mass to effectively control nuclear pollution in extreme accidents and improve the security level of nuclear power plants. The United States, Japan, the former Soviet Union, Europe and other countries and regions...
