MSR meaning

Published by a LexisNexis Energy expert
What does MSR mean?
In energy and nuclear regulation, MSR denotes a molten salt reactor, an advanced nuclear fission design using liquid salt as coolant and sometimes as fuel. The term is not defined in UK or Irish primary legislation or case law; it is a descriptive label used in policy and regulator guidance for advanced or advanced modular reactors. In England, Wales and Scotland, any MSR project would be treated as a nuclear installation requiring a nuclear site licence under the Nuclear Installations Act 1965, assessment by the Office for Nuclear Regulation and the relevant environmental regulator (for example, through the Generic Design Assessment and radioactive substances permitting), compliance with nuclear safeguards, and coverage by the UK nuclear liability regime. Planning and consenting would follow the major infrastructure regimes (for example, a Development Consent Order under the Planning Act 2008 in England and Wales, or section 36 consent under the Electricity Act 1989 in Scotland), subject to project size. Northern Ireland and Ireland have no nuclear generation; in Ireland, construction of nuclear fission power plants is prohibited, so MSRs arise mainly in research, export control and cross‑border regulatory contexts. As at present, no MSR has been licensed for commercial operation in the UK or Ireland.

Weekly environmental law update: COP30 outcomes; consultations, judgments and regulatory changes across climate, energy, permitting, ESG, marine, biodiversity, waste and water (4 December 2025)

In this issue: COP30 Key developments Air emissions and climate change Energy for environmental lawyers Environmental assessment Environmental information Environmental permits and consents ESG and sustainability Hazardous substances and chemicals Marine Nature, biodiversity and habitat conservation Waste Water, flooding and drainage LexTalk®Environment: a Lexis®Nexis community Daily and weekly news alerts New and updated content COP30 COP30’s Global ‘Collective Effort’—Fragments of progress By the Saturday morning when COP30 in Brazil should have concluded, negotiators secured an accord: ‘Global Mutirão: Uniting humanity in a global mobilisation against climate change’. Drawn from the Tupi-Guarani language, ‘Global Mutirão’ echoed a summit presented as one of action and delivery. The resulting text deliberately preserved the multilateral process and offered glimmers of progress, yet avoided any explicit mention of fossil fuels or of forests—despite the meeting taking place in the Amazon. This piece highlights the principal outcomes from COP30. Written by Estelle Dehon...

EU ETS: legal framework, Phase IV and ETS II reforms - scope, obligations, allowances, CBAM linkage, MSR, registry, market oversight, funds and key dates

EU ETS content—overview This Practice Note sets out a summary of the EU emissions trading system (EU ETS), previously referred to as the EU emissions trading scheme. It outlines the legal framework that underlies the ETS and the history of its staged roll-out, and gives a high-level view of its coverage, the principal duties on operators, the mechanisms for auctioning, free allocation, transfer and surrender of allowances, and how ETS proceeds are used. It also describes supporting legislation beyond Directive 2003/87/EC that enables the operation of the EU ETS, including the Regulation creating the EU carbon border adjustment mechanism (EU CBAM), the Market Stability Reserve Decision, the Union Registry Regulation, and market supervision measures. For further practical guidance on specific aspects of the EU ETS, see the following Practice Notes: EU Emissions Trading System (ETS) Phase IV—Directive 2003/87/EC EU Emissions Trading System (ETS) for aviation EU Emissions Trading System (ETS) for maritime transport EU Emissions Trading System (ETS) for buildings, road transport, and...

UK implementation and permitting under EU ETS Phase III: regulated activities, operator obligations, installation scope and thresholds, excluded installations and charges, with Brexit transition context (Archived)

Originally produced in partnership with Navraj Singh Ghaleigh, Senior Lecturer in Climate Law, University of Edinburgh ARCHIVED: This Practice Note has been archived and is not maintained. By traded volume, the EU Emissions Trading System (EU ETS) is the largest emissions trading scheme globally. It operates on a cap-and-trade model: a fixed ceiling is imposed on the total greenhouse gas (GHG) emissions from all participating sectors covered by the scheme, and that overall limit is translated into tradable allowances.
