#REACTOR IDLE OPTIMAL LAYOUT ISLAND GENERATOR#
Until now Siemens has offered parts and services for the 'conventional island' - the steam turbine, generator and cooling water systems. In general reactor vendors offer the so-called 'nuclear island' of a power plant - the nuclear steam supply system of the reactor vessel, pumps, pipes, steam generation and control systems. The EPR was jointly developed during the 1990s by Siemens and Framatome before the merger of their reactor businesses in 2001.Īreva is also completing a Siemens PWR, Angra 3, for Eletronuclear in Brazil, while Nucleoelétrica Argentina is completing a Siemens PHWR, Atucha 2.Īnother vestige of Siemens' solo work is Iran's Bushehr plant, which has recently been finished to a unique design by Russia's AtomStroyExport. While Siemens may not want to build any more reactors, parts of its former business are at work within Areva on EPR projects in China, Finland and France. Part of Siemens' nuclear business strategy was to remain as a specialist provider for the 'conventional island' of new nuclear power plants, as well as a provider of safety-critical instrumentation and control systems for new reactors, and it is these main areas that now stand to be discontinued. However, little concrete development followed the visit. Siemens said it left the Areva partnership to improve "entrepreneurial maneuverability" and within one week Löscher met Russian prime minister Vladimir Putin to discuss a "large-scale partnership" with Rosatom. Plant, built by Siemens, is the world's best performing, with lifetime loadįactor of 93% across more than 22 years of operation, according to Nuclear Engineering Internationl's Load Factor League Tables

But despite these issues, and their effects on utilities' maintenance plans, Siemens had already been restructuring and reducing its specialist nuclear businesses for several years - principally through the merger of its reactor business with that of France's Framatome in 2001, which it pulled out of in 2009 leaving Areva with full ownership and control. In an interview with Der Spiegel, CEO Peter Löscher said the company was influenced by the Fukushima accident and its impact on the German political situation. Siemens is one of the world's major firms in the energy sector and played a front-running role in the growing nuclear field of the 1970s and 1980s. The Kraftwerk Union technology - counted as part of Siemens - makes up the entire German nuclear fleet, while reactors were also exported to Argentina (Atucha 2), the Netherlands (Borssele), Switzerland (Goesgen), Spain (Trillo 1). The head of German industrial giant Siemens has said the company will withdraw its remaining nuclear power offerings and leave the industry.
