Japanese conglomerate Toshiba has said plans to win orders for nuclear reactors may have to be pushed back.
The company had been targeting 39 orders for nuclear reactors by March 2016, but those plans may be delayed.
Governments around the world have been tightening safety regulations in the wake of the March earthquake and tsunami in Japan.
Toshiba’s nuclear orders were expected to be worth around 1tn yen ($12.2bn; £7.6bn).
The industrial giant did say that orders for four AP1000 reactors in China would proceed as scheduled.
But countries such as the United States may be reconsidering their commitment to nuclear energy.
A massive earthquake and tsunami hit Japan on 11 March, causing a nuclear crisis in the country.
Toshiba is among those helping Tokyo Electric Power (Tepco) to get its crippled Fukushima nuclear facility under control.
Toshiba supplied some of the nuclear reactors at the Fukushima plant.
Fuel rods in three of the facility’s reactors were found to have been partially melted down.
