Safety and availability are the basic features of power equipment, power units and entire power plants regardless of the technology used to generate electrical and thermal energy. These requirements are of particular importance for controllable sources of energy generation, i.e. conventional and nuclear, in which, apart from the source of heat to generate steam, the remaining elements are generally the same or very similar. Servicing and diagnosing them has many common features. However, a specific feature of the transformation process of the Polish power sector so far is the decommissioning of coal-fired units at a faster pace than the construction of nuclear units. This may mean that such important technological local content may be a challenge, especially to the extent that Polish companies with high competences in the field of servicing and diagnosing power equipment can currently afford. Gas power plants may not meet these expectations because they are often built with even a dozen or so years of service from the supplier in the LTSA formula. During the Symposium, examples of modern servicing and diagnostics of equipment in nuclear and conventional power generation will be presented, also by Polish and foreign companies providing services simultaneously for both types of power plants.
A systemic approach to servicing and diagnostics will be presented, taking into account the identification of threats in the thermo-mechanical and physicochemical scope, also taking into account flexible operation of varying intensity. We assume that during the discussions accompanying the presented papers, there will also be room for presenting ideas and actions that would allow for the protection of the competences and capabilities of servicing and diagnostic companies during the period of shutdown of coal-fired power plants and waiting for the launch of the first nuclear unit and the next ones.
