France’s state auditor says French nuclear company EDF should not make a final investment decision until it has reduced its exposure to the Sizewell C reactor project at Hinkley Point C in England.

In a report on Tuesday, France’s corps des comptes said EDF must ensure that any international projects make “quantified profits” and should not delay the program of new nuclear projects in France.

The auditors’ opinion is unrelated to a Financial Times report on the construction costs of the Sizewell Sea project in Suffolk. It could reach £40bn.By 2020, it will double its estimate. Delaying the final investment decision from EDF could further delay the project and increase costs.

Asked about the FT’s report, a spokesman for Cour de Computes said the increase appeared “rational” given price increases on other projects.
