What is the role of nuclear energy related to carbon emissions?

The IEA report Nuclear Power in a Clean Energy System (May 2019) has this to say:

Nuclear power has avoided about 55 Gt of CO2 emissions over the past 50 years, nearly equal to 2 years of global energy-related CO2 emissions. However, despite the contribution from nuclear and the rapid growth in renewables, energy-related CO2 emissions hit a record high in 2018 as electricity demand growth outpaced increases in low-carbon power.

According to the chart copied here, nuclear energy generated more TWh then wind, solar, and other renewables combined in 2018. The report has eight charts with links to the data.
