Problems solved by technology

At present, my country has built two low-intermediate radioactive waste disposal sites near the surface in Northwest China and Guangdong Beilong. During the "13th Five-Year Plan" period, it plans to build five low-intermediate radioactive waste disposal sites. The currently built and proposed disposal sites are located in nuclear power plants or Near the nuclear facility, it receives the waste transported by several nearby nuclear power plants. The nuclear power plant and the low-intermediate radioactive waste site are planned and constructed separately, and the cost is relatively high

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.

[0024] refer to figure 1 , figure 2 , the present invention is an underground nuclear power plant with a disposal site for low and intermediate radioactive waste, including a nuclear island 1-1 and a conventional island 1-2, the nuclear island 1-1 nuclear-related buildings are placed in the cavern group of the nuclear island of mountain A, and the conventional island 1-2 is placed on the ground platform B outside the mountain body A. The nuclear island 1-1 also includes the low and intermediate radioactive waste disposal site 6 placed in the mountain A nuclear island cavern group, such as figure 1 shown.

[0025] In underground nuclear power plants, the nuclear-related core area plant is placed in the underground cavern. The core area plant is arranged in a ci...

Abstract

The invention discloses an underground nuclear power plant having a low-and-intermediate-level radioactive waste disposal site. The underground nuclear power plant comprises a nuclear island arranged in an underground cavern group of a nuclear island of a mountain and a conventional island arranged on a ground platform at the outer side of the mountain. The nuclear island consists of a reactor workshop arranged at the center, a nuclear fuel workshop, a safety workshop, an electrical workshop, and a nuclear auxiliary workshop, wherein the nuclear fuel workshop, the safety workshop, the electrical workshop, and the nuclear auxiliary workshop encircle the reactor workshop. And the nuclear island also includes a low-and-intermediate-level radioactive waste disposal site arranged in the underground cavern group of the nuclear island of the mountain; and the low-and-intermediate-level radioactive waste disposal site is communicated with the nuclear auxiliary workshop of the nuclear island by a waste transport tunnel. According to the invention, on the basis of combination of characteristics of the underground nuclear power plant, the processing requirement of the low-and-intermediate-level radioactive waste can be met, the closed circulation of fuels can be realized, and the radioactive contamination possibly occurring during the fuel cycle process can be reduced; and the unified planning and building of the nuclear power plant and the disposal site can be realized and costs are saved.

Description

technical field [0001] The invention relates to nuclear power technology, in particular to an underground nuclear power plant with a disposal site for low and intermediate radioactive waste. Background technique [0002] The low and medium radioactive waste generated by the operation and decommissioning of nuclear power plants mainly includes activated metal waste, waste resin, waste filter elements, radioactive evaporative concentrates, etc. Compared with high-level radioactive waste, its radioactive total specific activity accounts for a small proportion, but its volume is relatively large, which requires reasonable treatment and disposal. [0003] The radioactive waste generated during the operation and decommissioning of nuclear power plants is sorted in the nuclear waste plant, and the low and intermediate level waste is solidified and packaged for temporary storage, and finally transported to the disposal site for final disposal. The nuclear fuel cycle process in the n...
