Anti-nuclear protestors have gathered in Bowness-on-Windermere to demonstrate against plans to build an underground storage facility for radio-active waste.
Cumbria County Council and Allerdale and Copeland councils will decide on January 30th whether to proceed to the next stage in the plans.
But those who oppose the decision to site a geological waste facility in West Cumbria say are calling for an end to the "mad plan".
They are concerned about safety issues and add that it will damage the image of Cumbria as a tourist destination.
Cumbria County Council has said that no decision would be made about whether Cumbria should have a repository or not on January 30.
Instead, councillors will be deciding on whether geological experts should carry out the necessary work to see whether Cumbria could be the right location or not.
