In 2024, EDF DIPDE awarded GDES the contract for the design, manufacturing and operation of 2 Mobile Temporary Boron Injection Devices (DPMB). This project has an estimated duration of 7 years, including 5 years of operation and maintenance of the equipment, with 10 interventions at different nuclear power plants, both during outages and with the reactor in operation, at Nogent NPP, Paluel NPP and Saint Alban NPP.<\/p>\n

In 2024, EDF DIPDE awarded GDES the contract for the design, manufacturing and operation of 2 Mobile Temporary Boron Injection Devices (DPMB). This project has an estimated duration of 7 years, including 5 years of operation and maintenance of the equipment, with 10 interventions at different nuclear power plants, both during outages and with the reactor in operation, at Nogent NPP, Paluel NPP and Saint Alban NPP.<\/p>\n

\n

For this project, GDES established a partnership with the French company CSTI, a benchmark in the manufacturing and installation of special-purpose machinery in the French nuclear sector, jointly participating as a consortium (GME).<\/p>\n

In the context of the introduction of new fuels such as MOX (mixed uranium and plutonium oxide) and URE (reprocessed enriched uranium), the DPMB system enables the required boron concentration level to be achieved in the spent fuel pool and in the PTR system (Fuel Pool Purification, Treatment and Cooling System). For this reason, EDF will once again integrate our technological solutions into its facilities.<\/p>\n

Following the success of the UMB project (Mobile Boron Units), which positioned GDES in France as a reference in high added-value technology, the DPMB project reinforces this positioning, consolidating our presence in the French nuclear market. On this occasion, GDES will also assume responsibility for operation, thereby expanding our service portfolio for EDF across its entire nuclear fleet.<\/p>\n

After completing the design, procurement, and manufacturing phases, factory acceptance testing was carried out. This was a key stage in validating the proper operation of the device before its transfer and installation at the plant.<\/div>\n<\/div>\n

These tests, conducted between April and July 2026, comprised several stages aimed at thoroughly verifying all DPMB functionalities. They were performed at the facilities of CSTI, GDES\u2019s project partner, which are equipped with the necessary resources to carry out testing under configurations similar to those encountered during plant operation. Among these facilities is a dedicated test pit that makes it possible to reproduce representative conditions regarding the device\u2019s height above the boron injection point in the pool. This proved particularly useful for validating system performance under conditions closely resembling those of actual plant operation.<\/div>\n
\n

At present, with the design, procurement, and manufacturing phases completed, as well as the factory acceptance testing, the Device is ready to be installed at the plant and undergo operational commissioning, a key milestone scheduled for February 2027.<\/p>\n

\n
A strategic project for the Group that consolidates our position in France as a technology supplier to EDF, not only in the field of decontamination and surface treatment services, but also in the development, manufacturing and operation of critical equipment for nuclear plant operation and nuclear safety.<\/div>\n<\/div>\n<\/div>\n
