Ansaldo (formerly Breda) has been active in the
production of boilers, turbines and alternators for
nuclear plants since 1960. In 1991, it created the
“Nuclear Centre” in Milan, with the setting-up of
the Special Components Division, purchased in
April 2001 by the Camozzi group, thus creating
Ansaldo-Camozzi Energy Special
Components S.p.A.
Production
Ansaldo-Camozzi concentrates on the production
of components for the nuclear and conventional
sector and elements for transport and disposal of
exhaust nuclear fuel and heat exchangers for
nuclear plants. They also produce large
telescopes, the dimensions of which may be
generous - but tolerances certainly are not. The
concept of quality is not only a fundamental
pre-requisite within the nuclear industry where
safety must be 100% but, within
Ansaldo-Camozzi, it is a way of life.
Ansaldo-Camozzi was the first company outside
the U.S.A., to obtain the N and NTP ASME
Stamp. The list of ASME certificates in
accordance with the ASME III Division 1 is
impressive. The fact that they also achieved the
ISO 9001 2000 standard certification goes almost
without saying. To the contrary, the ASME N3
Stamp is extremely important and relates to the
design and manufacture of containers for holding
and transporting exhausted nuclear fuel elements.
This obviously implies that the welding materials
supplier also has to have the same quality
assurance prerequisites. ESAB Saldatura
(Welding) was the first company to achieve the
nuclear ASME Stamp certification, in Italy, for the
production of welding and cutting consumables.

using ESAB OK Flux 10.14. Once again, ESAB
achieved its objectives of quality, productivity
and cost saving – the same objectives set by
the customer.
Subsequently, a contract was signed for the
supply of a modern and sophisticated
two-headed cladding equipment.
ANSALDO-CAMOZZI producer of nuclear
and telescopic components
Ansaldo-Camozzi was created following the
acquisition by Camozzi, an industrial group from
Brescia, of the Special Components Division of
Ansaldo, specialists in the production of
components for the nuclear industry.
Ansaldo-Camozzi uses advanced technology for
production and quality control of the components
and is equipped with plants which are just as
advanced. For example, a press weighing over
6,000 tons, which can bend plates up to a
thickness of 300 mm, was recently used to make
the cover for the biggest heat exchangers ever
built in the world, weighing about 800 tons each
and destined for the largest American nuclear
power station, in Palo Verde, Arizona (Figure 6).
