New Prime Minister must lift existing barriers if nuclear energy is to help meet net zero target 鈥� new report
Experts from The University of Manchester鈥檚 Dalton Nuclear Institute - the largest and most advanced nuclear research capability in UK academia - have called on the government to do more to support the advancement of the UK鈥檚 nuclear energy capabilities, or risk failure in meeting its target of net zero by 2050.
The calls are accompanied by the publication of a new report authored by the senior leadership team at the Institute, which examines the obstacles that have prevented the adoption of advanced nuclear in the UK.
The new paper called, 鈥�, also sets out key recommendations on how the government can better facilitate a successful 鈥楾hree Wave鈥� rollout of nuclear energy in the UK.
This would see the staggered introduction of more traditional Light Water Reactors (LWRs), followed by their scaled down successor Small Modular Reactors (SMRs). SMR technology is set to gain regulatory approval by 2024, with Rolls Royce planning to design and deliver the UK鈥檚 first SMR by 2029.
Finally, Advanced Modular Reactors (AMRs) in the form of High Temperature Gas-cooled Reactors (HTGRs) make up the third wave, with ambitions to build an HTGR demonstrator by the early 2030s. HTGRs have additional utility beyond LWRs and SMRs, in that they can provide high temperature heat for use by industry in hydrogen generation.
Recommendations made in the report include quicker decision making to ensure that progress is made at the correct pace, as well as calls for the government to make a long-term commitment to the advancement of nuclear technology and to recognise the important role it has to play in reaching net zero.
The report comes as the Conservatives prepare to choose a new party leader and Prime Minister. The authors are urging the new administration to prioritise the advancement of nuclear power in the UK as a key policy in tackling the climate crisis.
Adrian Bull, BNFL chair in Nuclear Energy Systems at The University of Manchester鈥檚 Dalton Nuclear Institute, said: 鈥淔ollowing the publication of the Energy Security Strategy in April, it is now clear that the UK government sees a significant role for nuclear energy both in meeting the UK鈥檚 legally binding commitment to net zero, and in enhancing energy security.
It is also clear that new nuclear development in the UK will be driven by the private sector. The UK has historically been short-sighted in its nuclear policymaking, so the new Prime Minister must seize the opportunity to develop a suitable environment in which this investment can take place. This must be recognised as a priority, with there being slim chances of us reaching Net Zero without nuclear in the energy mix.
The full recommendations, as outlined in the report, are:
1. Government should develop, and communicate to the market, estimates of the size and utilisation of the potential HTGR fleet, including the power output of reactors envisaged, and the end use of the heat output.
2. Clear decisions should be made by government, for example in government-led competitions, to provide certainty to the market. While this will create winners and losers, government should be clear, consistent, and courageous in its decision making.
3. Government should make a clear, decades-long commitment to support advanced nuclear systems.
4. Nuclear programmes must move at the pace required to meet the 2050 net zero deadline, and government processes need to be able to keep up.
5. Developers should make efforts to engage early with regulators, to finalise a mature design and to establish a clear plan for the development of a site license holding entity. This should cover the whole span from reactor building, to decommissioning, and vacation of the site.
6. Fleet build of SMRs and HTGRs, combined with modular construction, are essential to achieve acceptable economics for these reactors. Competitions must be for quanta of work that are sufficiently large to justify investment by developers and sufficiently infrequent that they do not add significant delay to the programme.
7. To enable early, cost-competitive financing of nuclear investments, government should ensure that its developing Green Taxonomy properly reflects the sustainability benefits of nuclear energy and does not exaggerate its drawbacks.
