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

Petition Against the Building of SIZEWELL C on the Suffolk Coast

To Suffolk County Council, East Suffolk Council and Suffolk & Waveney District Council.

We sttrongly oppose the plan by EDFE to construct 2 new Nuclear reactors at Sizewell in Suffolk.
The destruction of AONB (Area of Outstanding Natural Beauty), SSSI sites (Site of Special Scientific Interest) and the proximity to Minsmere bird reserve, all on our crumbling Suffolk coastline, is totally unacceptable.
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 Sizewell for many years to come. SAY NO TO SIZEWELL C.
  • Please print off the petition and collect as many signatures as you can then return the forms to TASC before the end of March 2019.
Green Energy for the Wellbeing of Future Generations in Wales
We call on the National Assembly for Wales to urge the Welsh Government to invest in green renewable energy sources thus reducing the need for fossil fuels and nuclear energy in Wales. More specifically to
  • Support emerging low carbon technologies that could put Wales at the forefront of renewable energies and help to slow – down climate change; and
  • Invest in energy sources that do not leave a legacy of radioactive waste, spoil heaps and damage to health and the environment.

Halt the Dumping of Hinkley Mud in the Severn Estuary
To: Carwyn Jones AM, first minister of Wales and Government

Your ministers have failed to meet your duties on safeguarding our marine environment (UK Marine Act) and to comply with the international agreements (OSPAR, London anti-dumping Convention) on assessment of effects upon human health and marine flora and fauna. The mud was insufficiently tested at depth, with only 5 compared with the minimum 7 under OSPAR for the 300 000 tonnes. The Senedd Petitions Committee was right to ask for further testing and NRW wrong to refuse it, as the few deeper samples show up to 3 times more uranium and radium.

UK Government: Don't Risk Billions On Nuclear Power
Hitachi is demanding government funding to save its struggling nuclear power project. If something goes wrong, we could lose billions of pounds of public money.
We don’t need new nuclear plants. Offshore windfarms are already cheaper and quicker to build - and fast-improving energy storage tech means we can have clean, reliable power instead.
We’re asking Theresa May to drop this nuclear deal and back renewables instead. Will you add your voice?

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!"

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
