Bosco Marengo “Fabbricazioni Nucleari” (Nuclear Manufacturing) plant, built in the early Seventies, takes its name from the building company “Fabbricazioni Nucleari S.p.A.”. 

The plant activities, started in 1973, have produced fuel elements for the supply of Italian and foreign nuclear plants. 

From 1987, after the halt of nuclear activities in Italy, the plant has gradually modified its production, by focussing on advanced ceramic products (such as arthroplasty elements), industrial porous components for fuel cells, cutting-tools units and other products.

 In 1989, ENEA acquired the plant and, in 1995, any nuclear activity was halted. Since then, some traditional technological activities have been implemented while ensuring the safe maintenance of structures. In 2005, Sogin acquired the plant and the nuclear FN staff to implement decommissioning operations
