Scientists hoping to hide atomic discarded heavy underground person vowed that plans volition not spell up without section support.
Highly radioactive worldly equivalent successful size to 6,500 double-decker buses is presently stored supra crushed astatine 20 sites astir the UK. Some silos are opening to deteriorate with age.
Nuclear Waste Services (NWS), a authorities agency, says burying it successful the bedrock offers a agelong word solution, harmless from terrorism, warfare and earthy disasters.
It is consulting with the coastal communities of Allerdale, Mid-Copeland and South Copeland successful Cumbria, and Theddlethorpe successful Lincolnshire, astir gathering a geological disposal installation (GDF) nether the seabed.
Prof Neil Hunter, main idiosyncratic for NWS, told Sky News: "If we supply a compelling case, if we supply the grounds to show safety, and the assemblage wants to proceed, past a determination tin beryllium taken to bash so.
"But a assemblage holds the close of withdrawal."
The authorities is committed to a caller procreation of atomic powerfulness stations, with the Chancellor Jeremy Hunt this week announcing successful the fund plans for tiny standard reactors.
But with nationalist consultations implicit the siting of a GDF apt to proceed for respective years, discarded is continuing to heap up successful aboveground retention silos.
There is nary program B if a consenting assemblage cannot beryllium found.

Prof Hunter said: "If we were to beryllium unsuccessful (in winning support) it would beryllium for the authorities to bespeak connected the mode forward. But internationally it is the solution.
"We person assurance that this is simply a harmless mode guardant for radiological discarded management."
What happens if plans get the go-ahead?
If the program gets the go-ahead radioactive discarded would beryllium taken into a immense warren of tunnels by train.
Heavy work canisters would beryllium sealed into the bedrock, plugged with clay to support retired water, and the full analyzable sealed implicit erstwhile full.
Scientists accidental the installation would beryllium unchangeable implicit the hundreds of thousands of years that the radioactive worldly would instrumentality to go safe.
'I privation to marque definite the discarded is successful the safest spot it tin be'
At a nationalist engagement lawsuit successful Seascale, a colony conscionable 2 miles from the Sellafield atomic tract successful Cumbria, locals were overwhelmingly supportive.
David Moore, a farmer, said: "Sellafield has brought large economical benefit.
"But the assemblage recognises that determination is discarded determination present and it has to beryllium managed successful a harmless way.
"We can't support passing it down the generations. I've got 7 grandchildren and I privation to marque definite the discarded is successful the safest spot it tin be."
But determination is besides immoderate opposition.
Keith Hudson, a retired subject teacher, backs geological disposal arsenic the safest solution.
But helium fears underground h2o and the analyzable geology successful Cumbria marque the determination excessively risky.
"They cognize the geology is amended successful the eastbound of the country, wherever they could physique a GDF large capable and bash truthful quicker, amended and cheaper," helium said.
But determination is nary atomic manufacture adjacent the projected GDF tract successful Lincolnshire, dissimilar successful Cumbria, and making the lawsuit to the section assemblage whitethorn good beryllium harder.
"That's the occupation with the full process. It's not being driven by the subject oregon the economics, but by politics," Mr Hudson said.
Less than 1 successful a cardinal accidental of radioactivity returning to surface
NWS insists that immoderate h2o successful the bedrock disconnected the Cumbrian seashore is static oregon dilatory moving, and not a risk.
It says the plan rule for the GDF is that determination volition beryllium little than 1 successful a cardinal accidental of radioactivity returning to the aboveground to harm people.

Independent scientists hold it is the champion solution to the atomic industry's discarded legacy.
Prof Claire Corkhill, who studies however atomic worldly degrades astatine the University of Sheffield, said: "We are not conscionable pouring glowing greenish goo into the ground.
"If you deliberation of the Russian doll concept, you person got the discarded wrong a container, which is surrounded by a buffer worldly that acts similar sponge to mop up immoderate water. All of that is encased successful coagulated rock.
"The lone mode we tin stably power our radioactive discarded successful a harmless and predictable mode is heavy underground."
