Large power reactors
Designed for substantial grid supply. Project development must align licensing, construction, cooling, transmission and long-term operations.
Official AP1000 resource →TECHNOLOGIES
Nuclear energy.
Different scales. Shared questions.
A practical guide to civilian nuclear technologies, with clear distinctions between established operation, development and future proposals.
Small modular reactors
The IAEA commonly defines SMRs as up to 300 MWe per unit. Commercial use of the SMR name varies between vendors and jurisdictions.
Read the IAEA explanation →Modular delivery
Factory production and repeatable designs can change delivery methods. Claimed savings depend on actual programmes and cannot be assumed for every project.
Read a vendor approach →A technology name is not a project status.
Keep four questions separate: Is the design available? Has the relevant regulator authorised the specific activity? Is a project being built? Has the plant entered commercial operation?
Development, design review, construction permission and operation are distinct milestones. A design selected for one country does not automatically have approval in another.
