Supersafe and simply- / easily-decommissionable nuclear power plant

Abstract

The invention relates to an inexpensively- / easily-decommissionable nuclear power plant, where a nuclear isle of one or more nuclear power-stations is installed in caverns, and further, side by side with them, a centre for characterising, treating and conditioning radioactive wastes and two repositories are installed in suitable caverns, with a final repository being adapted to store low-intermediate level nuclear wastes and a temporary repository being adapted to store spent fuel, high-level long-life radioactive materials and, in case, spare nuclear rods for reactor refuelling.

Description

technical field

[0001] The invention relates to a nuclear power plant with safety features of the highest level, which can be dismantled with certainty, easily and very cheaply at the end of its service life.

[0002] More specifically, the present invention relates to the planning of nuclear power systems such that their radioactive components are safely located underground covered by rock of sufficient thickness, together with associated facilities for the disposal and treatment of radioactive waste. The plan allows for an absolute environmental and population protection with safe and easy demolition. Background technique

[0003] Conventional power plants for producing electrical energy from controlled nuclear fission reactions are today designed and constructed in such a way that the major components making up the plant, especially the nuclear island, flow generator, turbine / The generator island and safety protection plant are located above the soil surface.

Examples

Embodiment Construction

[0037] in the attached figure 1 , shows the layout of a modern EPR nuclear power plant according to known technology, which includes: a reactor building 1, a fuel building 2, a safeguard building 3, a diesel emergency generator building 4, an auxiliary nuclear building 5, a nuclear waste building 6 and Turbine Plant 7.

[0038] go to figure 2 , in the plant according to the present invention, all radioactive components, the associated safety guard buildings and emergency generators are provided in underground cavities dug for this purpose, which are of sufficient size and depth and are accessible through equipped access ramps and / or the vertical shaft is connected to the ground. Thus, the entire nuclear assembly can be isolated from the outside world.

[0039] In this way, the following components of the PWR nuclear power plant are located in underground caves:

[0040] - Reactor / steam generator / pressurization unit;

[0041] - Safety protection plant;

[0042] - contro...
