Let an agent explain how nuclear reactors work and the main types, relay safety, regulation and statistics from official sources, present debates about nuclear power with attribution, and keep to general engineering description without design or security-sensitive detail.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain how nuclear reactors work and the main types, relay safety, regulation and statistics from official sources, present debates about nuclear power with attribution, and keep to general engineering description without design or security-sensitive detail.

A device that initiates and controls a sustained nuclear fission chain reaction, using fuel such as uranium or plutonium, a moderator in thermal reactors, control rods and a coolant, to produce heat for electricity generation, propulsion, research or isotope production; reactor types include pressurised and boiling water reactors, gas-cooled designs such as Magnox, heavy water, fast and advanced concepts such as supercritical water reactors and microreactors, and reactors are licensed and inspected under national and international safety regimes.

What it is for: Producing heat for electricity, propulsion, research and isotopes.

It can be explain principles and types; relay safety and regulatory frameworks; relay statistics from official sources; present debates with attribution.

Distinguishing features

Controlled fission

Moderator and coolant design

Containment and safety systems

Strict licensing

What it looks like

A reactor vessel within a containment building, with cooling systems and, at power plants, turbine halls and cooling towers.

Physical character

power reactors operating worldwide: about 410-440 count - per IAEA, recent years

share of world electricity: about 9-10 percent - recent years

How it is recognised

Controlled fission chain reaction

Power, research and propulsion types

Nuclear weapons use uncontrolled reactions; fusion reactors are experimental and different

What the second pass must settle

  • How should IAEA data be linked?
  • The registry entry has merged aliases naming specific designs; should they be split off?
