An International Atomic Energy Agency (IAEA) team of experts has completed a review of long term operational safety at the Doel Nuclear Power Plant (NPP) Units 1 and 2 in Belgium operated by Engie Electrabel.
The SALTO (Safety Aspects of Long Term Operation) follow-up review mission was requested by the Belgian Federal Agency for Nuclear Control (FANC). Doel’s Units 1 and 2 went into operation in 1975. FANC approved a 10-year extension of the units’ operating license in December 2015, provided that a set of safety conditions is fulfilled every year.
During the 25-28 June mission, the SALTO team reviewed Doel’s response to recommendations and suggestions made during an initial SALTO mission in 2017.
The team—comprising seven experts from Canada, the Czech Republic, South Africa, Sweden, Switzerland and the IAEA—said that plant management had improved organizational arrangements to support aging management for the period of long term operation (LTO). They had also updated the Safety Analysis Report with aging management and LTO assessment results and enhanced competence and knowledge management for plant personnel involved in aging management.
Further work is necessary to ensure that all required structures and components are included in the scope of aging management during the LTO period, the IAEA said. It was also recommended that management complete the implementation of the aging management programs for civil structures and components.
Plant management expressed a determination to continue to address the remaining issues and to continue safe LTO of the NPP.
The team provided a draft report to the plant management and the FANC at the end of the mission. The plant management and FANC will have an opportunity to make factual comments on the draft. A final report will be submitted to the plant management, FANC and the Belgian Government within three months.
