Investigations of subterranean microorganisms. Their importance for performance assessment of radioactive waste disposal

Abstract

This report presents a broad and thorough description of how microorganisms may influence safety of repositories for radioactive waste. First, an overview of the Swedish concepts for disposal is given, including a discussion of the geological, chemical and hydrological conditions in repositories. Then the limiting and stimulating factors for life of microorganisms are reviewed, such as relations to oxygen, temperature, pH, radiation, pressure, water and nutrients availability. Bacteria in the cycles of carbon, nitrogen, sulfur, iron, manganese and hydrogen are also discussed. A literature review of subterranean bacteria is given in chapter 4. Chapter 5 treats investigations of microorganisms in repository-like environments, and microbial corrosion and redox processes relevant for materials in the repository and for the mobility of radionuclides. Possibilities to predict the activity and presence of microorganisms through mathematical models are discussed in chapter 6. Chapter 7 summarizes the conclusion drawn in the report, how microorganisms may influence performance safety assessment of radioactive waste disposal, and also identifies research needs. 293 refs, 43 figs, 36 tabs.
