Walter Tosto WTB, Formerly Fecne Nuclear Components, was one of the main suppliers of pressure vessels, heat exchangers and heavy welded structures in Romania. The company started its activity as a part of Heavy Machine Works Bucharest (IMGB) established in 1968.
Fecne was an important point in the collaboration program between the French and Romanian governments (1979), as J-F Mitterrand provided to Ceausescu the drawings and the specifications of the Framatome Usine (today AREVA Saint Marcel).
In 1980, under Atomic Energy of Canada Ltd (AECL), Fecne began to manufacture heavy welded components for nuclear power plants. In 1991 Fecne became an independent Company.
In 1982 Fecne was mainly involved in the manufacturing of critical items such as Calandria (reactor vessel), Steam Generators, Pressurizer, D2O Vapour recovery system, Fuel Channel bars, Heat Hexchangers and service vessel, Air lock channel, Steam surface condenser, HP and LP Feed water heater for Cernavodă Nuclear Power Plants in Romania, as well as Candu 6 in Canada.
From 1998 it became a part of Kvaerner as Kvaerner Fecne SA.
In 2006 Fecne entered judicial reorganization and liquidation and in 2011 was bought by Romenergo.
In July 2012 the company was acquired by Walter Tosto Spa, which, having identified a significant growth potential for the company, completely refurbished and reorganized the whole structure.
At today Walter Tosto WTB’s infrastructure is completely renewed with energy efficient improvements, new machinery equipment and modern facilities for employees.
