Helping nuclear plants all over the world to optimize their processes, improving safety and efficiency


At Tecnatom we have been supporting nuclear plants all over the world for over 60 years, offering reactor services and technology for operations, construction and for long term operations. This allows Tecnatom to offer solutions to nuclear plants throughout their lifecycle, from the design phase, to the commissioning, operation or decommissioning.

We offer solutions based on our own technology which optimise operation, maintenance and reloading processes, reducing times and improving the investments made by our clients.

We have a wide set of skills for multiple nuclear reactor technologies, which can be fully adapted to the needs of each plant. More information on our nuclear products and services can be found in the menu located to the right side of this page.

International Presence

Tecnatom has projects in over 40 countries, demonstrating its comprehensive knowledge of all types of commercial reactor technologies.

From conventional BWR (boiling water) or PWR (pressurised water) technologies seen worldwide, to VVER (pressurised water) and RBMK  (graphite-moderated) technologies  more commonly seen in Eastern Europe, Russia and Ukraine, as well as PHWR (heavy pressurised water) technology seen in Argentina, APR-1400 (pressurised water) technology in the UAE, AGR (gas and graphite) technology in the UK and other advanced design nuclear plants such as AP-1000 (pressurised water), ABWR (boiling water) and other types of reactors such as the CPR1000 (pressurised water) seen in China.

New Reactors

Tecnatom has been ever-present in the development of new nuclear reactor technology, and we have provided support to the nuclear programs of various countries. This can be seen by our presence in the commissioning of the Lungmen ABWR reactor, the training of the AP-1000 personnel in China and the United States, our contribution to the nuclear programs in the UAE and China and the relaunch of nuclear programs in the UK and Argentina.
We also heavily participate in international reactor research, such as for the international nuclear fusion project (ITER), the Jules Horowitz reactor (France), Halden (Norway) and the IFMIF facility (Japan).
