NEA panel on AI hosted at World Governments Summit
A panel on the potential of artificial intelligence to accelerate small modular reactors was held at the World Governments Summit (WGS) in February in Dubai, United Arab Emirates. The OECD Nuclear Energy Agency cohosted the event, which attracted leaders from developers, IT companies, regulators, and other experts.

The neutron and fusion rate enhancement from in-flight reactions created by knock-ons from fission fragment slowing down in a compressed eqi-molar DT-plutonium plasma has been calculated. The neutron enhancement is worth up to a factor-of-2 reduction in critical mass. However, the neutron e-folding time is on the order of the system disassembly time, thereby restricting the multiplication of the neutron population to a factor of 2 or 3. It therefore appears more appropriate to discuss fission in a thermonuclear plasma in terms of a fusion chain reaction (fission fragment amplification of the fusion rate) rather than a fission chain reaction (neutron enhancement and criticality).
