EP’s Energy Progress Tracker (EPT) includes the most comprehensive country-by-country review of every nuclear reactor that has ever been in operation globally with the goal of assessing the state of nuclear energy technology.

EP’s assessment takes into account both quantitative and qualitative data, and uses both objective and subjective metrics. A detailed discussion of the methods used are available through the link below.

The table below lists EP's ratings for all currently operating reactors based on their risk of closure by 2030.

More information on how EP assigned a rating to each reactor can be found in the methodology. Each number in the rating system is briefly defined as follows, with 1 indicating little to no risk of early plant closure and 5 indicating the highest risk.

1: reactor is highly likely to be remain in operation
2: reactor is highly likely to be refurbished and/or relicensed and remain in operation
3: reactor is facing threats to continued operation
4: reactor is unlikely to remain in operation
5: reactor is highly unlikely to remain in operation

The table below lists EP's ratings for all reactors currently under construction based on their risk of closure by 2030. This assumes that plants become operational before 2030.

More information on how EP assigned a rating to each reactor can be found in the methodology. The ratings in this table follow the same definitions as those assigned to currently operating reactors.

The table below lists EP's ratings for all reactors that are planned based on their likelihood of being online by 2030.

More information on how EP assigned a rating to each reactor can be found in the methodology. Each number in the rating system is briefly defined as follows, with 1 indicating a high likelihood of being online and 3 indicating a low likelihood.

1: projects with signed contracts for near-term initiation of construction; often, these projects will have initiated site work
2: projects with signed commercial agreements and announced dates
3: announced in some sort of official plans by entities known to be serious about nuclear energy, but with uncertain dates and details
