[Machine Translation] During the planned annual maintenance at the end of October at Doel 3 an in-depth degradation was detected in a bunker. This bunker houses the so-called emergency systems, these are the 2nd level systems such as emergency pumps and bunk diesel generators. The operation of these emergency systems must be guaranteed at all times, with the building being able to resist any event. With the established grazing degradation this can not always be demonstrated, resulting in an increased risk in an external accident. The state of the concrete is therefore strengthened during this maintenance and must be completed for the re-launch of Doel 3. After analysis, this event was currently classified as INES-1. INES (International Nuclear Event Scale) is a communication tool that allows to quickly and comprehensively represent the severity of an incident involving ionizing radiation. This scale counts seven levels, ranging from 1 (anomaly) to 7 (severe accident). Further analyzes are ongoing, which may lead to an adjustment of the level to INES-0 or a non-safety-related deviation.
