Power generation and nuclear fuel processing disposal integrated nuclear energy base based on closed cycle

Abstract

The invention discloses a power generation and nuclear fuel processing disposal integrated nuclear energy base based on closed cycle. The power generation and nuclear fuel processing disposal integrated nuclear energy base comprises a nuclear energy power generation area, a spent fuel and waste disposal area, and a waste final disposal area. The nuclear energy power generation area comprises a reactor workshop, a nuclear auxiliary workshop, and a fuel workshop. The spent fuel and waste disposal area comprises a spent fuel and waste disposal workshop and a waste processing workshop. The waste disposal area comprises a commissioned near surface disposal warehouse, a decommissioned near surface disposal warehouse, a middle depth disposal warehouse, and a deep geological disposal warehouse. The nuclear energy base is divided into the power generation area, the fuel and waste disposal area, and the waste final disposal area according to functions, and the planning, the siting, and the investment of the whole nuclear energy base are realized in a unified manner, and therefore planning is facilitated, and factory site resources are saved. The spent fuel and the wastes are processed and disposed in the neighborhood, and therefore radiation risks caused by long distance transport are prevented.

Description

technical field [0001] The invention belongs to the technology of underground nuclear power plants, and specifically refers to a closed cycle-based integrated nuclear energy base for power generation and nuclear fuel treatment and disposal. Background technique [0002] The nuclear fuel cycle, with nuclear power plants as the demarcation point, is divided into the front section and the back section of the cycle. The front section of the cycle includes uranium mining, uranium enrichment and fuel preparation, etc., which are generally completed in uranium mining areas and uranium enrichment plants; For reprocessing and the treatment and final disposal of the three nuclear wastes, according to the relevant laws and regulations of our country, the spent fuel is implemented in a closed cycle, and the post-reactor uranium and plutonium in the spent fuel are recovered through the reprocessing plant, and the remaining high-level radioactive waste is processed. [0003] At present, t...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the shortcomings of the above-mentioned existing background methods, and propose a closed-cycle integrated nuclear energy base based on power generation and nuclear fuel treatment and disposal, which not only solves the problem of site selection for nuclear power plants, but also reduces the nuclear power caused by site dispersion. Security is difficult, and it avoids possible nuclear leakage during long-distance transportation of spent fuel and nuclear waste. It can also share the functional area of ​​the process system of the nuclear power plant, and the overall economy is better.
