1. Five priorities for Nuclear Britain
- New nuclear power. Expand Britain's nuclear generating capacity through additional large-scale nuclear power.
- Small Modular Reactors. Support deployment of smaller reactor designs as part of a diversified nuclear programme.
- Nuclear research. Invest in research, skills and technologies needed to sustain a long-term domestic nuclear capability.
- Grid resilience. Strengthen the electricity system needed to connect and support dependable generation.
- Fuel security. Reduce exposure to international energy shocks by strengthening the security of Britain's energy supplies.
The working master commits to redirecting a major proportion of energy levies currently associated with decarbonisation towards these priorities. It does not specify a cash amount or final split between them.
2. The policy commitment
Energy security. A stronger domestic nuclear base.
The master sets out the commitment as follows:
A major proportion of energy levies currently associated with decarbonisation will be redirected toward:
- new nuclear power;
- Small Modular Reactors;
- nuclear research;
- grid resilience;
- fuel security.
The objective will be a substantial expansion of Britain's nuclear generation capacity.
3. Redirect existing energy-levy funding
The proposed funding mechanism is to redirect a major proportion of energy levies currently associated with decarbonisation.
This is a reallocation within the wider energy programme rather than a new levy created by this proposal.
4. Strengthen energy security
A larger source of dependable domestic generation is intended to reduce Britain's exposure to international fossil-fuel markets and the price shocks that can accompany them.
The proposal deliberately includes both new large-scale nuclear power and Small Modular Reactors as part of the expansion of Britain's domestic generating capacity.
5. Put affordability alongside security
The policy is intended to support lower and more stable energy bills over the long term by expanding dependable domestic supply.
6. What would need to be developed
The master establishes the direction of travel but not a complete delivery plan. Implementation would need to address:
- the balance between large-scale nuclear plants and SMRs;
- project sequencing;
- regulation;
- skills;
- grid connections;
- fuel strategy;
- waste and decommissioning;
- and the amount of levy funding redirected.
How this fits the wider energy programme
Nuclear Britain follows Proposal 11's pragmatic Net Zero approach. Together, the two releases place affordability, energy security, industrial competitiveness and technological readiness alongside decarbonisation.
Part V also addresses domestic oil and gas, a social energy tariff and abolition of domestic standing charges.
7. Questions for public scrutiny
What balance between large nuclear plants and SMRs would provide the best combination of reliability, speed and value for money?
What proportion of current decarbonisation-related energy levies should be redirected, and what existing programmes would be affected?
What evidence and milestones should be required before claiming that expanded nuclear generation will lower household bills?
How should Britain build the skills, supply chains, grid capacity and fuel security needed for sustained nuclear expansion?
