List Version Source flow Name there Why this flow
agribalyse 3.2 606db44d-eb69-51b0-af44-0bdcf4720334 Uranium-238 The CAS numbers are the same (24678-82-8); both name the same compartment.
bafu 2026-v1 1b5acbc4-9c26-5f17-a68a-2ec9b0b96e10 Uranium-238 The CAS numbers are the same (24678-82-8); both name the same compartment.
bafu 2026-v1 e9d389c5-07d4-5fda-a61c-750d77dd188f Uranium-238 The CAS numbers are the same (24678-82-8); both name the same compartment.
ecoinvent 3.12 16cd83f0-c5c0-4b6f-8dd0-26d4e3b9a017 Uranium-238 The CAS numbers are the same (24678-82-8); no flow of this substance sat in that compartment, so this one was created for the row.
ecoinvent 3.8 16cd83f0-c5c0-4b6f-8dd0-26d4e3b9a017 Uranium-238 The CAS numbers are the same (24678-82-8); both name the same compartment.

Characterisation factors

3

Every implementation that says anything about this flow. Published as is what this list did with the row: where more than one implementation states a number and they agree it publishes it as agreed; where only one speaks, as sole; where they disagree it publishes nothing and asks.
