Learn the lessons from nuclear projects elsewhereby Malcolm Grimston / February 27, 2017 / Leave a comment
The recent troubles at Toshiba concerning their US nuclear arm, Westinghouse, for which costs have substantially overrun, demonstrate again that nuclear construction is an economically risky business. Since most of the cost of nuclear power goes on building the machine in the first place, anything that results in overruns in the initial schedule, in terms of time or cost, represents a serious threat to the finances of the scheme and indeed its investors.
The building of the first new UK nuclear power station in over twenty years is now underway at Hinkley Point in Somerset, to be financed by EDF Energy and CGN from China at a total projected cost of £18bn. It is to use the Evolutionary Power Reactor (EPR) designed and built by Areva, the French nuclear plant service company. Hinkley Point C will represent the fifth and sixth such reactors to be ordered, behind one for each of Olkiluoto (to be operated by TVO, Finland), Flamanville (EDF, France) and two at Taishan in Guangdong Province, China (CGN). The two European schemes are heavily over time and budget, while a further six-month delay in commissioning the two Chinese plants has just been announced.
