Toshiba aims to wind up its UK nuclear business after failing to find a buyer, dealing a potentially fateful blow to plans for a new nuclear power station in Cumbria.
Its NuGen arm was behind the development of the Moorside project.
Toshiba’s decision will dent the UK’s procedures to develop new nuclear power stations.
Unions have criticised the oversight for failing to intervene and ensure the project went ahead.
The Japanese establish said it would start the wind-up process in January.
“After all in all the additional costs entailed in continuing to operate NuGen, Toshiba recognises that the economically ratiocinative decision is to withdraw from the UK nuclear power plant construction throw, and has resolved to take steps to wind-up NuGen,” the Toshiba statement bid.
Korea Electric Power Corporation (Kepco) had been a preferred bidder to settle over the nuclear power plant project, but those talks floor through after more than a year of negotiations.
Toshiba conveyed it expected to take a 15bn yen ($131.8m; £100.5m) hit from the withdrawal, but shares in the limited company jumped 12.7% in Tokyo.
The GMB union said the “looming collapse” of Moorside had been “depressingly liable”.
“Relying in this way on foreign companies for our country’s essential energy scarcities was always irresponsible,” said its national officer Justin Bowden.
“A new atomic power station in West Cumbria remains vital for the UK’s future pep security and requires urgent action.”
In September NuGen announced it was decrease its team at Moorside from more than 100 to fewer than 40 – primary to speculation the plant’s development was in jeopardy.
NuGen was initially co-owned by Toshiba and the French steady Engie. Toshiba was subsequently forced to buy the remaining 40% of NuGen it did not already own via a bankruptcy train related to Engie.
