David Davis will push ahead with plans to pull Britain out of the European civil nuclear regulator during Brexit talks in Brussels next week.

The Government has said though that European Union treaties are "uniquely legally joined" with Euratom and insisted there is a "strong mutual interest" for close co-operation once the UK has left the bloc.

In the second round of negotiations with the EU's chief Brexit negotiator Michel Barnier, Mr Davis will call for minimised civil nuclear trade barriers after the divorce.

Papers setting out the Brexit Secretary's position say the UK is "keen to discuss this as quickly as possible" and wants a "smooth transition" with no interruptions in the safeguard arrangements.

The Government's position paper says consideration will be given to ownership of Euratom equipment and special fissile material.

Documents have also been released setting out how Mr Davis will approach legal proceedings in Europe in the talks and what will happen with protections for EU organisations in the UK.

Mr Davis will reaffirm the Government's position that the Court of Justice of the European Union should not be allowed to rule on UK cases that were not before the court on the day of Brexit.

Immunities for diplomats and privileges for EU bodies, such as the European Medicines Agency, should be extended for a short time after Britain quits to allow operations to be wound up, the papers say.

Mr Davis said: "While we're leaving the EU we are not leaving Europe, and we want to continue co-operating with our friends and neighbours on issues of mutual importance including nuclear safeguards.

"By ending the jurisdiction of the Court of Justice of the European Union, UK courts will be supreme once more. Our sensible approach to pending cases means there would be a smooth and orderly transition to when the court no longer has jurisdiction in the UK."

Sue Hayman, the MP for Workington, was worried by the news.

She said: "I am really, really concerned about the impact on the nuclear industry if we leave Euratom.

"I have not met a single person from the nuclear industry who has said this is not a really, really bad idea."

"Those of us who represent the nuclear industry in parliament will continue to press the Government."

Mrs Hayman is co-chairman of the of the all-party group on nuclear energy, which is pushing for a meeting with Business Secretary Greg Clark on the subject of Euratom membership.

Barrow MP John Woodcock commented on the news and also spoke about the issue in the House of Commons yesterday.

He said:“I am glad that Euratom is finally getting some attention from the government after it seems they made the initial decision to withdraw the UK without any consultation, but this paper will do little to reassure people in Cumbria.

“I made it clear to the minister in the debate on Wednesday that the cloud of uncertainty around our membership of Euratom is harming the Moorside project that is set to create 21,000 jobs in Cumbria over the coming years.

“I have been pushing to keep full or associate membership for months and I am glad that some Tory MPs are now waking up to the damage they are causing, the government must listen to the industry and change course.”

Tom Greatrex, chief executive of the trade body the Nuclear Industry Association, said: "While containing very little detail, the UK Government's position paper demonstrates the complexity of replicating Euratom arrangements in UK regulation and co-operation agreements with third countries which the industry has warned of. Government must therefore make the need for transitional arrangements its starting point in negotiations. Failure to do so will risk precisely the disruption the government state they want to avoid.

"It remains the UK nuclear industry's view that retaining Euratom membership will best serve the national interest. It may also be the most straightforward, seamless and sensible way to achieve the government's stated preferred outcome is through the associated membership the Euratom treaty enables. Exploring that should be a priority in discussions with European institutions.

He added: "The Government has also said it wishes to provide "certainty and clarity" to industry. Given the lack of clarity to date, it is imperative now that the government ensures there is regular and ongoing dialogue with industry so there is a full appreciation of the practical, logistical and administrative consequences of these negotiations."

The Royal College of Radiologists (RCR) has issued a warning that anything hitting the supply and transport of radioactive isotopes widely used in scans and other treatment could cause delays for patients.

The RCR said it remains concerned over the disruption of supply of medical materials once the UK is outside the nuclear common market, through higher costs, increased regulation or trade barriers.

Many of the medical materials used in treatment reach the UK via EU-based nuclear reactors, the college said.

Nicola Strickland, president of the RCR, said: "As a medical royal college, our primary goal is to ensure the safe and reliable delivery of medical services to patients who need scans and non-surgical cancer treatment.

"This is why we are calling for further clarity and dialogue on the future supply of radio isotopes.

"The Government has promised a statement on the matter. We hope that will be issued very soon and give the assurance that patients and doctors need."

Brexit minister Steve Baker said fears raised by medical experts over the impact of quitting Euratom are "not correct".
