Ecological and sociodemographic consequences of hydrotechnical construction (Problems of safety and risk)

Application of a logical-probabilistic method of failure and fault trees for predicting emergency situations at pressure hydraulic facilities (the case of Kakhovka hydroelectric complex)

“…In many cases, pressure hydraulic facilities (especially dams, spillways) play the role of the last reserve to prevent a man-made catastrophe in emergency operation usually by emergency operation of the reservoir. In this case, the emergency operation of the reservoir can also lead to catastrophic consequences, including the destruction of hydraulic facilities with a breakthrough of the pressure waterfront [14,15].…”

“…In particular, [7,8] indicate the importance of the scenario approach in assessing the safety of hydraulic facilities and [10] indicates the need to take into account their interaction as part of hydroelectric complexes. In [14,15], various problems of reliability and safety of hydraulic facilities are formulated within the framework of the probabilistic approach with the analysis of the factors determining the reliability and safety of hydraulic facilities of different type and purpose. In [16,17], the results of statistical analysis of the accident rate of hydraulic facilities depending on their type are given.…”

Considering the risk of unused opportunities when grounding the optimal scenario of commissioning of new units at pumped storage power plants in Ukraine

“…Будівництво та експлуатація гідроенергетичних об'єктів, як показує практи-ка, пов'язуються зі значним ризиком [8][9][10][11], детальний аналіз, адекватна кількісна оцінка і належне врахування якого під час прийняття рішень являє собою надзвичайно складну міждисциплінарну проблему [10,[12][13][14][15][16].…”
