Nuclear power reactors, reactor types and technologies | IAEA
Nuclear power reactors produce energy by initiating and controlling a sustained nuclear chain reaction. Currently, over 400 such reactors in 32 countries provide about 10 per cent of the world’s electricity. The IAEA fosters an international information exchange and collaboration on technological innovations in different reactor technologies.

Large Reactors Poised to Lead the Nuclear Power Expansion as Small ...
Large water cooled reactors were central to the rise of the nuclear industry in the 20th century, and the advanced reactors planned or under construction today, many of which are in the 1–1.7 gigawatts (electrical) (GW (e)) range, are poised to provide the bulk of new nuclear capacity.

Fast-neutron reactors, Fast nuclear reactors | IAEA
Sodium cooled fast reactors, lead and lead–bismuth cooled fast reactors and gas cooled fast reactors are currently being developed at national and international levels in compliance with higher standards of safety, sustainability, economics, physical protection and proliferation resistance. In addition, the molten salt fast reactor concept is being considered as a long term option.

What are Molten Salt Reactors (MSRs)? | IAEA
Molten Salt Reactors (MSRs) are nuclear fission reactors in which either the fuel and/or the coolant is a molten salt. Molten salt is salt which liquifies at elevated temperatures and can store massive amounts of thermal energy at atmospheric pressure. When used as fuel the molten salt is dissolved with fissile material.
