Resumo
Countries around the world have made an international commitment to decrease the amount of greenhouse gas
emissions by 2030 according to the Paris Agreement. Among several power stations options of low carbon
emissions, nuclear energy has been proved the most reliable source for electricity production. According to the
sustainable development scenario targets, nuclear energy should play an important role in the next years for the
decarbonization of the energy system. Countries with consolidated nuclear programmes such as Canada and the
UK have similar nuclear fuel technology development, but they have chosen different nuclear fuel cycle options:
open fuel cycle and closed fuel cycle, respectively. Both of them have future plans to continue with their nuclear
programme. Therefore, this works evaluates the nuclear energy systems for three different scenarios for high,
basic and low production of nuclear energy for both countries. The results compare the resources needs, the
economy of the nuclear fuel cycle options, the policy of each country and the future of the nuclear power plants
to achieve the reduction of the greenhouse gases. The main findings are that reprocessing is a good option for the
UK for the whole or partial new nuclear fleet and becomes viable if the price of uranium increases in the market.
For Canada, it is worth continuing to increase its nuclear energy up to 1.5 times its current energy capacity. The
main difference between the programmes of the two countries is the higher amount of spent fuel generated in the
case of Canada due to the choice of reactor technology.
