Outokumpu Supplies Quarto Plate for Nuclear Fusion Research
12/23/2011 - Outokumpu has won a tender to supply 350 tonnes of quarto plates for a fusion experiment project in Japan called JT-60SA. The stainless steel plates, made out of low cobalt 304, will be used in the cylindrical section of the cryostat, which is the hull surrounding the main components of the Tokamak reactor.
Outokumpu has won a tender to supply 350 tonnes of quarto plates for a fusion experiment project in Japan called JT-60SA. The stainless steel plates, made out of low cobalt 304, will be used in the cylindrical section of the cryostat, which is the hull surrounding the main components of the Tokamak reactor. Fabrication of the cryostat vessel body cylindrical section will be done in Spain for Japan Atomic Energy Agency.
The mission of the JT-60SA project is to contribute to the early realization of fusion energy by supporting the ITER (International Thermonuclear Experimental Reactor) project in identifying and exploring how to operate fusion power reactor plasmas in the demonstration electricity-generating power station (DEMO) that should follow ITER.
In April 2011, Outokumpu also delivered about 355 tonnes of the same material to IDESA for the fabrication of the base of the same cryostat for CIEMAT (Centre for Energy-Related, Environmental and Technological Research) in Spain.
Construction and utilization of the JT-60SA takes place in Naka, Japan, under the Satellite Tokamak Program as part of the Broader Approach agreement signed between Japan and European Atomic Energy agencies.
"Outokumpu has a long track-record in supplying stainless steel to the nuclear industry where projects have high standards for product safety and reliability. Stainless steel with low cobalt content is particularly used in core structures in nuclear equipment where, for example, corrosion resistance, permeability, and cleanliness requirements are decisive," said Hirokuni Yoshida, head of Outokumpu sales office in Japan.
