How two cutting edge U.S. nuclear projects bankrupted Westinghouse, Reuters, | WILMINGTON, DEL./NEW YORK, 2 May 17
In 2012, construction of a Georgia nuclear power plant stalled for eight months as engineers waited for the right signatures and paperwork needed to ship a section of the plant from a factory hundreds of miles away.
The delay, which a nuclear specialist monitoring the construction said was longer than the time required to make the section, was emblematic of the problems that plagued Westinghouse Electric Co as it tried an ambitious new approach to building nuclear power plants.
The approach – building pre-fabricated sections of the plants before sending them to the construction sites for assembly – was supposed to revolutionize the industry by making it cheaper and safer to build nuclear plants.
But Westinghouse miscalculated the time it would take, and the possible pitfalls involved, in rolling out its innovative AP1000 nuclear plants, according to a close examination by Reuters of the projects.
Those problems have led to an estimated $13 billion in cost overruns and left in doubt the future of the two plants, the one in Georgia and another in South Carolina.
Overwhelmed by the costs of construction, Westinghouse filed for bankruptcy on March 29, while its corporate parent, Japan’s Toshiba Corp, is close to financial ruin [L3N1HI4SD]. It has said that controls at Westinghouse were “insufficient.”
The miscalculations underscore the difficulties facing a global industry that aims to build about 160 reactors and is expected to generate around $740 billion in sales of equipment in services in the coming decade, according to nuclear industry trade groups.
The sector’s problems extend well beyond Westinghouse. France’s Areva is being restructured, in part due to delays and huge cost overruns at a nuclear plant the company is building in Finland………
the source of the biggest delays can be traced to the AP1000’s innovative design and the challenges created by the untested approach to manufacturing and building reactors, according to more than a dozen interviews with former and current Westinghouse employees, nuclear experts and regulators.
Unlike previous nuclear reactors, the AP1000 would be built from prefabricated parts; specialized workers at a factory would churn out sections of the reactor that would be shipped to the construction site for assembly. Westinghouse said in marketing materials this method would standardize nuclear plant construction..…..
By 2016 Westinghouse began to grasp the scope of its dilemma, according to a document filed in its bankruptcy: Finishing the two projects would require Westinghouse to spend billions of dollars on labor, abandoning them would mean billions in penalties.
Westinghouse determined it could not afford either option. http://www.reuters.com/article/us-toshiba-accounting-westinghouse-nucle-idUSKBN17Y0CQ
