The majority of reactors in operation around the world are considered second generation and third generation reactor systems, as the majority of the first generation systems have been retired. China was the first country to operate a demonstration generation-IV reactor, the HTR-PM in Shidaowan, Shandong , [ 7 ] [ 8 ] which is a pebble-bed type ...
The Nigeria research reactor (NIRR-1) is a nuclear research reactor located in Zaria, Nigeria. The reactor is located at the Centre for Energy Research and Training (CERT), part of Ahmadu Bello University. The reactor had its first criticality in 2004, launched by the then director of CERT, Prof. Ibrahim Musa Umar and is the only nuclear ...
Since 2004 Nigeria has a Chinese-origin research reactor at Ahmadu Bello University, and has sought the support of the International Atomic Energy Agency to develop plans for up to 4,000 MWe of nuclear capacity by 2027 according to the National Program for the Deployment of Nuclear Power for Generation of Electricity.

An international coalition is advancing research and development on six Generation IV nuclear reactor technologies. The Generation IV International Forum (GIF), initiated by the US Department of Energy in 2000 and formally established in 2001, is a collaborative platform for 13 countries where nuclear energy is significant or crucial for future ...
Classed as a Generation IV reactor, it features a fast-neutron spectrum and closed fuel cycle for efficient conversion of fertile uranium and management of actinides. The reference reactor design is a helium - cooled system operating with an outlet temperature of 850 °C (1,560 °F) using a direct Brayton closed-cycle gas turbine for high ...
Yet, in many ways, the hurdles facing this new generation of reactors have mirrored the old. Advanced reactor designs have taken longer than projected. Those delays have added to cost overruns.
However, a number of proposed and one in construction new nuclear reactor designs are lead-cooled. Fuel designs being explored for this reactor scheme include fertile uranium as a metal, metal oxide or metal nitride. [2] The lead-cooled reactor design has been proposed as a generation IV reactor. Plans for future implementation of this type of ...
Sketch of a pebble-bed reactor. The pebble-bed reactor (PBR) is a design for a graphite-moderated, gas-cooled nuclear reactor. It is a type of very-high-temperature reactor (VHTR), one of the six classes of nuclear reactors in the Generation IV initiative. Graphite pebble for reactor. The basic design features spherical fuel elements called ...
