Lead fast reactor
Also written LFR
Molten lead or lead-bismuth coolant, fast and unmoderated. Does not burn in air or react violently with water, unlike sodium, at the cost of weight and corrosion engineering. Fuel is typically nitride or mixed-oxide.
In the record: 3 companies, 1 laboratory or programme, 2 reactors and 3 reactor designs.

Size class is worked out from the electrical output of one unit: up to 10 MWe is a microreactor, up to 300 MWe a small modular reactor. A design with no stated output is not classed.
| Design | Developer | Electrical output per unit | Size class | Licensing stage |
|---|---|---|---|---|
| LFR-AS-200 | newcleo | 200 MWe planned | Small modular reactor | No milestone recorded |
| SEALER-55 SEALER | Blykalla | 55 MWe planned | Small modular reactor | No milestone recorded |

Measurements
2 reactors using this approach carry 2 measurements: 2 planned. The values, each with its status and source, are on the benchmark and on each device's page. Most measured: BREST-OD-300 (1), MYRRHA (1).
