Non-nuclear Power Generation

Centrum výzkumu Řež also deals with fossil-fuelled power plants – especially the material issues – using unique research facilities and knowledge and experience of its specialists. An example of the non-nuclear research is given by the “PRAMEK” project.

PRAMEK

The influence of the working medium on the constructional materials used in the water-steam circuit of power plants.

The project aim is to develop methodology of evaluation, monitoring equipment and the optimal combination of material and water chemistry for supercritical water-cooled, fossil-fuelled power plants and fossil-fuelled power plants with high performance steam. Project studies the issues of compatibility of materials used or designed for the energy systems with supercritical water (typically: 600 °C, 25 MPa) and high performance water steam (570 °C and 17 MPa). O2, NH3 are used as suitable agents serving to modify the chemical conditions.. Studied materials used to produce the most vulnerable parts of the devices are f.e. T24, P91, P92, CB2, 1.4913. Basic activities of the projects are:

  • Exposure of the specimen of chosen materials to the environment of supercritical water and high performance water steam using the Supercritical Water loop and Supercritical autoclave in Centrum výzkumu Řež
  • Analyses of the exposed samples will be done by NRI; the Institute of Chemical Technology, Prague; and Centrum výzkumu Řež and will be focused on the changes in mechanical properties, microstructure, surface structure and properties of protective layers

The project consortium involves the research companies Centrum výzkumu Řež and the Institute of Chemical Technology, the engineering company NRI, the provider of plant components ŠKODA POWER and the operator ČEZ a.s., which covers the whole life cycle of the plant and focuses the project on the correct applicable direction of its outputs.
