There are several anti-nuclear petitions online that you can support.
Here are some of them:

Allow Parliament a vote on planned Hinkley Point C and Bradwell nuclear power plants
The decision to accept the investment from EDF and China to design, build and operate the first new (as yet untested) nuclear power stations in a generation must be made only with the consent of parliament.
The petition has been started by Steven Hale. He is a retired engineer who believes he represents the mass of public opinion.
The deadline is 16 March 2017
At 100,000 signatures, this petition will be considered for debate in Parliament. Sign petition here:
Switch to the Renewable Plan B for Hinkley C – fit for the 21st Century
Theresa May's Government is reviewing the Hinkley C nuclear reactor project
This expensive white elephant would hand the keys of Britain's future energy security to the Chinese and French Governments, while blocking investment and grid access for faster and cheaper renewable energy alternatives

UK Government: Don't Waste £Billions on Nuclear Power
Philip Hammond, the new Chancellor of the Exchequer, is overseeing plans to build a new nuclear power station at Hinkley Point. The power plant's already 8 years overdue. And by the time it's finished it'll be the most expensive object on earth..
While Hinkley continues to suffer huge delays, and serious questions are being raised about the safety of the reactor, the cost of renewable energy is falling.
Rumours are now spreading that EDF - the company that wants to build Hinkley - could pull out of the deal, meaning the whole project could be on the rocks.
Let's seize this moment to pile the pressure on Philip Hamond - the new Chancellor. A huge petition could convince him to abandon the project and back renewable energy instead.

Don't Nuke The Climate
Don't Nuke the Climate!
Seven international clean energy organizations launched a major campaign in support of a nuclear-free, carbon-free energy system and to prevent nuclear power from being considered as a climate solution when the world's governments meet at the COP 21 conference in Paris in December 2015.

Stop Moorside

A petition has been set up to STOP MOORSIDE, described by the industry as "the biggest nuclear development in Europe".  Despite having no solution to the problem of nuclear waste our government is hell bent on trashing a large swathe of Cumbria in order to build new nuclear reactors. To quote Michael Meacher MP: "We need new nuclear like we need a hole in the head!"

16 Aug 2012: E-petition now closed.

07 Dec 11: Hinkley Point nuclear protesters take fight to Prime Minister David Cameron: Campaigners yesterday stepped up their battle against a new nuclear power station in Somerset by handing a major petition to 10 Downing Street. More >>>

To the Secretary of State for Energy and Climate Change

Hinkley Point C Nuclear power station

We, the undersigned, strongly oppose the plan by EdF to construct a new nuclear power station at Hinkley Point in Somerset. Instead, a government-backed programme of energy saving and clean renewable energy would combat climate change and avoid the risks of a catastrophic accident, dangers to health and the storage of highly radioactive waste at Hinkley for 160 years.


We reached over 13,000 signatures. Many thanks to everyone for your support
