Limiting Factors for Survivability and Proliferation of Microorganisms Significant for Corrosion of Deep Geological Repository Barrier Systems

Aim of the project is to determine values of the physical factors limiting the survival and proliferation of naturally occurring microflora in deep water and bentonite and to propose a standardized method which enables efficient estimation of these values in any type of bentonite and water in the future.The project will primarily focus on the effects of pressure, temperature, irradiation and water and nutrient availability, which are the key factors negatively influencing the survival and proliferation of bacteria in repository conditions. The limiting factor values will be tested on a Czech bentonite candidate together with the reference purified bentonite Nanocor of defined chemical composition and without natural microflora.Other outputs-functional sample,proven technology,publications.
