  "conversion_factor": 560000.0,
  "conversion_comment": "Like peat, this already reaches the right flow, on a cas+label match, and reaches it with the units disagreeing and no factor. 560000 MJ/kg is fission energy content on a gross basis, not a calorific value: four orders of magnitude above any combustion figure, because the two quantities are related by fission rather than burning, and it must never be read as a heating value. IPCC Table 1.2 lists no value for uranium at all -- it is a table of combustion fuels -- so the number is the one this project already carries for ecoinvent's `Uranium` onto this same target, from the EF 3.1 LCIA method as implemented by the ecoinvent Centre. BAFU's `resources / in ground` compartment, which is the only resource context EF 3.1 gives uranium."
