TL;DR — The UK is set to benefit from Amazon-backed X-energy's plans to deliver 11 gigawatts of power through small modular reactors, with 144 orders already booked.
Why it matters
- This initiative could significantly contribute to the UK's energy transition and reduce reliance on fossil fuels.
- The project may attract further investment in the UK's nuclear energy sector, enhancing job creation and technological innovation.
- Successful implementation of these reactors could position the UK as a leader in small modular reactor technology.
Explainer
X-energy, a nuclear energy startup supported by Amazon, has announced that it has secured orders for 144 small modular reactors (SMRs), which are expected to generate over 11 gigawatts of power. This development is particularly relevant to the UK, where there is a growing interest in diversifying energy sources and reducing carbon emissions. Small modular reactors are seen as a viable solution to meet energy demands while also addressing environmental concerns. The UK government has been actively promoting nuclear energy as part of its strategy to achieve net-zero emissions by 2050. If X-energy’s plans come to fruition, it could not only bolster the UK’s energy capacity but also stimulate the domestic economy by creating jobs in construction, operation, and maintenance of these reactors. Furthermore, the success of SMRs could encourage additional investments in nuclear technology, reinforcing the UK's position in the global energy market.
