The power capacity growth to meet increasing electricity demand is complicated by a significant number of power units having operating lifetime expired. However, the domestic and foreign practice shows that the actual operating life of power units is often substantially longer than it is claimed by manufacturers. Lifetime extension of existing power units is a common international practice ensuring power generation at the achieved level until new power generating capacity is put into operation. The article provides analysis of the current state of power equipment of Ukrainian thermal and nuclear power plants. The main differences and problems in assessment of remaining service life of critical components of TPP and NPP units are comprehensively considered. A comparative analysis of domestic and foreign methods for equipment remaining life assessment is provided. The main problem of ensuring sustainable unit performance is raised within the article.Посилання
