Sizewell A was built in the 1960s and work started on Sizewell B in the 1980s
Parliamentary candidates for the Suffolk Coastal have given their views on plans for a new generation of nuclear power station - one of which could be sited in the constituency.
In November last year, the government approved 10 sites in England and Wales for new nuclear power stations, most of them in locations where there are already plants.
They included Sizewell, near Leiston on the Suffolk coast, where the Sizewell A nuclear power station was built in the 1960s and Sizewell B built at the end of the 1980s and the start of the 1990s.
Conservative candidate Therese Coffey said: "In the medium term for energy needs there is a need for nuclear power. A nuclear power station at Sizewell makes sense. For the local economy it would be very good news."
'Keep lights on'
She said she hoped that instead of temporary houses for new workers on a new station, she wanted to see affordable homes built there which could boost the housing stock for the county in the future.
She said any plans for a new power station could also help provide funds for improving the A12.
Labour candidate Adam Leeder said: "I am all in favour of it. I am an advocate of nuclear power. A third of our energy is going to have to be replaced over the next decade.
"Nuclear power is the only way to keep the lights on."
He said it would bring in "more high-value jobs". He said he also supported investment in renewable energy such as wind farms and wave power.
Daisy Cooper, the Liberal Democrat candidate said it was important that there is a public inquiry into the "risks, costs and benefits" of any plan to build a new nuclear power plant at Sizewell.
She said there are security concerns and concerns about possible flooding.
Ms Cooper added: "There are still a few unanswered questions. I don't think we should rush into it."
She said there would also be benefits from a new power station such as new jobs.
The candidates announced for the Suffolk Coastal constituency are: Conservative: Therese Coffey; Labour: Adam Leeder; Liberal Democrats: Daisy Cooper; Green Party: Rachel Fulcher; UK Independence Party: Stephen Bush
