Abstract

Nuclear energy accounts for a significant part of the total energy production in the Czech Republic, which is currently facing a problem dealing with the high-level radioactive waste (HLW) and the spent nuclear fuel (SNF). Deep repository is the safest option for storage of HLW. Rock environment of the area must guarantee the stability of the deep geological repository for at least 100,000 years. The aim of the research is a long-term evaluation of the climatic changes of the hypothetical area of interest, which corresponds to the candidate sites for deep geological repository in the Czech Republic. The occurrences of endogenous and exogenous phenomena, which could affect site stability, were evaluated. Concerning exogenous processes, research focuses mainly on the assessment of climatic effects. The climate scenarios for the Central Europe were examined – global climate change, glaciation, and the depth of permafrost as well as CO2 increase.

Highlights

  • Many developed and developing countries all over the world including the Czech Republic produce an important portion of energy in nuclear power plants

  • There are two nuclear power plants in the Czech Republic – Dukovany and Temelín. Those countries have recently faced a problem of dealing with the high level radioactive waste (HLW) and the spent nuclear fuel (SNF) disposal

  • In the Czech Republic spent nuclear fuel and high level radioactive waste are stored in interim storage facilities, which are situated near the nuclear power plants

Summary

Introduction

Many developed and developing countries all over the world including the Czech Republic produce an important portion of energy in nuclear power plants. In the Czech Republic spent nuclear fuel and high level radioactive waste are stored in interim storage facilities, which are situated near the nuclear power plants. The occurrence of endogenous and exogenous phenomena that could affect the stability of the candidate sites is evaluated. These are the expected climate changes and their impact on the rock environment – global climate change, glaciation and increase of CO2 during the climate warming. The aim of further research will be the evaluation of the geological environment evolution in term of endogenous and exogenous phenomena that affect the stability of the site
