answer	answer is ministerial correction date of answer 14/07/2023 answer text <p>.</p><p>Nuclear power continues to be an important and proven source of reliable, clean energy, and as a result of this strong baseload provision, we have been able to move faster on a number of our key net zero objectives.</p><p> </p><p>A proportion of the nuclear generating capacity is likely to be unavailable at any given point due to routine inspections, maintenance, energy systems management and technical issues. A certain level of outage is to be expected and demonstrative of a very well regulated and safe technology.</p><p> </p><p>In 2021, nuclear power stations generated 46 TWh of electricity which was 15% of the electricity generated in the UK. The UK’s Advanced Gas Cooled Reactor Fleet is ageing and has performed beyond original expectations providing extra years of generation.</p><p> </p><p>In addition to the AGR fleet, Sizewell B will continue operating until at least 2035 and we have set out our ambition for a new generation of nuclear power stations, providing up to 24GW of electricity by 2050. The new reactor designs are very efficient. This includes new large-scale nuclear power stations like Hinkley Point C which alone will provide 3.2GW for around 60 years, and the next generation of small and advanced reactors are expected to be more efficient.</p><p><strong> </strong></p><p><strong> </strong></p><p><strong> </strong></p><p><strong>2010 – 2023 (June): Annual number of outages and non-operational days at UK nuclear power

answer	answer is ministerial correction date of answer 14/07/2023 answer text <p>.</p><p>Nuclear power continues to be an important and proven source of reliable, clean energy, and as a result of this strong baseload provision, we have been able to move faster on a number of our key net zero objectives.</p><p> </p><p>A proportion of the nuclear generating capacity is likely to be unavailable at any given point due to routine inspections, maintenance, energy systems management and technical issues. A certain level of outage is to be expected and demonstrative of a very well regulated and safe technology.</p><p> </p><p>In 2021, nuclear power stations generated 46 TWh of electricity which was 15% of the electricity generated in the UK. The UK’s Advanced Gas Cooled Reactor Fleet is ageing and has performed beyond original expectations providing extra years of generation.</p><p> </p><p>In addition to the AGR fleet, Sizewell B will continue operating until at least 2035 and we have set out our ambition for a new generation of nuclear power stations, providing up to 24GW of electricity by 2050. The new reactor designs are very efficient. This includes new large-scale nuclear power stations like Hinkley Point C which alone will provide 3.2GW for around 60 years, and the next generation of small and advanced reactors are expected to be more efficient.</p><p><strong> </strong></p><p><strong> </strong></p><p><strong> </strong></p><p><strong>2010 – 2023 (June): Annual number of outages and non-operational days at UK nuclear power

answer	answer is ministerial correction date of answer 14/07/2023 answer text <p>.</p><p>Nuclear power continues to be an important and proven source of reliable, clean energy, and as a result of this strong baseload provision, we have been able to move faster on a number of our key net zero objectives.</p><p> </p><p>A proportion of the nuclear generating capacity is likely to be unavailable at any given point due to routine inspections, maintenance, energy systems management and technical issues. A certain level of outage is to be expected and demonstrative of a very well regulated and safe technology.</p><p> </p><p>In 2021, nuclear power stations generated 46 TWh of electricity which was 15% of the electricity generated in the UK. The UK’s Advanced Gas Cooled Reactor Fleet is ageing and has performed beyond original expectations providing extra years of generation.</p><p> </p><p>In addition to the AGR fleet, Sizewell B will continue operating until at least 2035 and we have set out our ambition for a new generation of nuclear power stations, providing up to 24GW of electricity by 2050. The new reactor designs are very efficient. This includes new large-scale nuclear power stations like Hinkley Point C which alone will provide 3.2GW for around 60 years, and the next generation of small and advanced reactors are expected to be more efficient.</p><p><strong> </strong></p><p><strong> </strong></p><p><strong> </strong></p><p><strong>2010 – 2023 (June): Annual number of outages and non-operational days at UK nuclear power

answer	answer is ministerial correction date of answer 14/07/2023 answer text <p>.</p><p>Nuclear power continues to be an important and proven source of reliable, clean energy, and as a result of this strong baseload provision, we have been able to move faster on a number of our key net zero objectives.</p><p> </p><p>A proportion of the nuclear generating capacity is likely to be unavailable at any given point due to routine inspections, maintenance, energy systems management and technical issues. A certain level of outage is to be expected and demonstrative of a very well regulated and safe technology.</p><p> </p><p>In 2021, nuclear power stations generated 46 TWh of electricity which was 15% of the electricity generated in the UK. The UK’s Advanced Gas Cooled Reactor Fleet is ageing and has performed beyond original expectations providing extra years of generation.</p><p> </p><p>In addition to the AGR fleet, Sizewell B will continue operating until at least 2035 and we have set out our ambition for a new generation of nuclear power stations, providing up to 24GW of electricity by 2050. The new reactor designs are very efficient. This includes new large-scale nuclear power stations like Hinkley Point C which alone will provide 3.2GW for around 60 years, and the next generation of small and advanced reactors are expected to be more efficient.</p><p><strong> </strong></p><p><strong> </strong></p><p><strong> </strong></p><p><strong>2010 – 2023 (June): Annual number of outages and non-operational days at UK nuclear power

answer	answer is ministerial correction date of answer 14/07/2023 answer text <p>.</p><p>Nuclear power continues to be an important and proven source of reliable, clean energy, and as a result of this strong baseload provision, we have been able to move faster on a number of our key net zero objectives.</p><p> </p><p>A proportion of the nuclear generating capacity is likely to be unavailable at any given point due to routine inspections, maintenance, energy systems management and technical issues. A certain level of outage is to be expected and demonstrative of a very well regulated and safe technology.</p><p> </p><p>In 2021, nuclear power stations generated 46 TWh of electricity which was 15% of the electricity generated in the UK. The UK’s Advanced Gas Cooled Reactor Fleet is ageing and has performed beyond original expectations providing extra years of generation.</p><p> </p><p>In addition to the AGR fleet, Sizewell B will continue operating until at least 2035 and we have set out our ambition for a new generation of nuclear power stations, providing up to 24GW of electricity by 2050. The new reactor designs are very efficient. This includes new large-scale nuclear power stations like Hinkley Point C which alone will provide 3.2GW for around 60 years, and the next generation of small and advanced reactors are expected to be more efficient.</p><p><strong> </strong></p><p><strong> </strong></p><p><strong> </strong></p><p><strong>2010 – 2023 (June): Annual number of outages and non-operational days at UK nuclear power
