Toshiba's US nuclear problems could provide cautionary tale for UK

Experts say construction delays and cost problems at two plants are due to lack of experience and absence of supply chains

The roots of Toshiba's admission this week that it has serious doubts over its "ability to continue as a going concern" can be found near two small US towns.

It is the four reactors being built for nuclear power stations outside Waynesboro, in Georgia, and Jenkinsville, South Carolina, by the company's US subsidiary Westinghouse that have left the Japanese corporation facing an annual loss of 7.37bn.
