У цій статті наведені основні результати аналізу експлуатаційних подій на АЕС України та світу, пов’язаних з захисною оболонкою та системами, які забезпечують її працездатність.

Основною метою цього аналізу було здобуття загальних та конкретних уроків, які дозволять запобігти повторенню подій у майбутньому. Обсяги аналізу охоплюють структурні елементи споруди захисної оболонки та інші системи, необхідні для забезпечення її функціонування. Під час проведення аналізу розглянуті експлуатаційні події розділено на категорії (ті, що впливають або можуть вплинути на виконання захисною оболонкою своїх локалізуючих функцій, і ті, що не впливають). Встановлено, що до категорії подій, що впливають на виконання захисною оболонкою проєктних функцій, належать випадки відмови арматурних канатів  системи переднапруження захисної оболонки і ці випадки розглянуто детально, починаючи з 1980 року з урахуванням історії та причин зміни проєктних значень зусиль натягу арматурних канатів.
