nuclear reactor
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
