Enhanced CANDU 6

The Enhanced CANDU 6 (EC6) is a 700-megawatt (MWe) Generation III reactor based on the highly successful CANDU 6 reactor, with a number of safety enhancements included to meet the latest Canadian and international standards.

The EC6 uses natural uranium as a fuel, a heavy-water moderator and heavy-water coolant in a pressure-tube design. It can be refueled on power and has one of the highest lifetime capacity factors among the world’s reactors.

These features make the EC6 ideal for small and medium electric grids.

Advanced Fuel CANDU Reactor

The Advanced Fuel CANDU reactor (AFCR) is an evolutionary 700 MWe Generation III reactor based on the highly successful CANDU 6 and Enhanced CANDU 6 (EC6) reactors with a number of adaptations to meet the latest Canadian and international standards.

The AFCR’s fuel flexibility allows it to use recycled uranium or thorium as fuel. It has a heavy-water moderator and, a heavy-water coolant, and a pressure tube design.

Like all CANDU reactors, it can be refuelled on-power and has one of the highest lifetime capacity factors among the world’s reactors.
