Nuclear decommissioning definition

What does Nuclear decommissioning mean? Nuclear decommissioning describes the legal and regulatory process for planning, defuelling, dismantling, decontaminating and remediating a nuclear site that has ceased operation, managing radioactive waste and spent fuel, and restoring the land either to an unrestricted, delicensed condition or to a state suitable for alternative use.

What is the impact of Brexit on the UK nuclear sector?

On 31 January 2020 (‘exit day’), the UK stopped being a Member State of the EU.

Leaving the EU also entailed departure from the Euratom Community. At 11 pm (GMT) on 31 December 2020, the transition/implementation period ended. This moment, termed ‘IP completion day’ in UK law, brought transitional measures to a close and triggered substantial changes across the UK’s legal framework.

Tomlin orders in England and Wales: CPR guidance on drafting, confidentiality, approval, variation, enforcement, limitation, CCA issues, court-specific requirements, sample wording and precedents

This Practice Note This Practice Note reviews mechanisms used in settling litigation. A Tomlin order consists of a consent order paired with a schedule. It operates to stay proceedings on terms that have been agreed. The provisions contained in the schedule may remain confidential. This Practice Note describes the scope of confidentiality attaching to the schedule and sets out how it differs from a standard consent order. Sample wording for a Tomlin order is included, alongside links to precedents, as well as guidance on court approval. It also addresses varying, setting aside and enforcing a Tomlin order, including the considerations the court will take into account when handling applications for each. Further guidance is provided on interpreting and applying the relevant provisions of the CPR; however, some courts and divisions impose very specific requirements for both drafting and approval, and for approaching the schedule and confidentiality issues. Accordingly, you must consider the particular rules and court guide provisions in the forum where your claim is proceeding when drawing up the Tomlin order...
