“…Based on the proposed method of considering the defect resulting from the operation of energy equipment and the corresponding cyclic loads, and using the determined stress intensity coefficients, the estimation of remaining service life and safety prediction for further operation is suggested. Some research [9,13] proposes mathematical models to analyze the changes in the mechanical properties of the metal pipeline, such as R T m , (ultimate tensile strength), R T p0.2 (yield strength), Z T (total elongation), A T (reduction of area), K SI (stress intensity coefficients), and others, considering the regularities of metal property changes during operation. These models take into account the geometry of the defect and the accumulation of fatigue damage in equipment and pipelines under different operational loads.…”

“…Thus, nuclear energy plays a vital role in promoting sustainable economic development and maintaining its reputation as a "green" energy necessitates the active involvement of all stakeholders in ensuring operational safety. As indicated in references [7][8][9][10][11][12], the shift towards a circular, "green" economy is a gradual process, and the energy sector necessitates support and diligent attention to safety at every level and stage of power facility equipment operation.…”

The study considers ways to ensure the quality of the functioning of power equipment as one of the directions for ensuring the safety of energy complexes in the period of “green transformation”. Based on the analysis, it is established that for an effective “green” transformation, it is necessary to ensure the energy safety of equipment operation, which is possible by developing effective science-based approaches to technical diagnostics of the state of power systems and individual equipment. The main objective of the study is to develop a Safety Management Model for Life Term Operation of power equipment, which takes into account changes in its condition at different stages of operation and allows for the prediction of further safe operation. The paper proposes an approach to researching the technical condition of power equipment, taking into account the deformations that occur during operation. The results of the calculation of stress intensity coefficients for longitudinal and transverse-postulated cracks in different modes are presented. Based on the calculated and experimentally obtained values, an approach to predicting the operating life of power equipment with regard to changes in technical characteristics is proposed. The results of the calculations showed that by changing the allowable load on the material of the energy equipment to 35 kgf/mm2, the estimated operational lifespan could be extended until 2035, ensuring all necessary safety conditions. It has been proven that with effective management and continuous safety diagnostics, nuclear power plants have the potential to operate beyond their standard design life of up to 30–40 years. This approach allows for the quality and safe operation of power equipment in the context of the transition to sustainable energy.

“…The authors proposed a comprehensive diagnosis of power equipment and forecasting of the service life based on a study of the stress-strain state of elements and calculation of the residual life by analyzing the degree of metal degradation. Based on the proposed methodology for determining the number of permissible load cycles under different operating conditions, the authors of [4,17,20] proposed a model for managing the safety of nuclear power units using international regulatory and legislative requirements, as described in [18,[23][24][25], and an algorithm for predicting further operations within the design and beyond the design life.…”

The study considers approaches to ensuring energy management for the safe operation of facilities and their equipment and ways to improve it. It has been established that to ensure effective safety management of industrial enterprises, one of the critical areas is the technical diagnostics of power equipment during operation. An assessment of the actual technical condition of power equipment of VVER-1000 power units is proposed based on establishing the aging mechanisms and determining the relative evaluation coefficients for the characteristics of individual equipment elements. The results of the calculations allowed us to conclude that the obtained results correspond to the coefficients of relative assessment Ki of the technical characteristics of the power equipment that determine its degradation. Studies indicates that when assessing the state of power equipment, it is necessary to consider the presence and impact of the following operational factors that are not considered in the design calculations: loads, high levels of mechanical stress, fatigue damage, and metal defects, which primarily indicate the presence of degradation changes. To assess the technical condition of the equipment, considering the degree of mechanical wear, 17 technical characteristics were selected to determine the aging mechanisms by signs of degradation. A mathematical model of the dependence of the relative evaluation coefficient K on changes in the operating parameters is presented, and it is noted that the most significant influence on the value of the coefficient is the temperature of the coolant at the inlet (K = 0.56). The developed approach makes it possible to improve the safety management system of power facilities by introducing the proposed model to assess the technical conditions of power equipment by defining the parameters in the overall safety management system.
