List	Version	Source flow	Name there	Why this flow
EF	3.1	08a91e70-3ddc-11dd-9c45-0050c2490048	uranium-238	The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
agribalyse	3.2	e3966f7f-c4d9-509d-8619-42b8ddae7fd5	Uranium-238	The CAS numbers are the same (24678-82-8); both name the same compartment.
ecoinvent	3.12	3c5a2d44-0206-427c-b34e-3b871077bd40	Uranium-238	The CAS numbers are the same (24678-82-8); both name the same compartment.
ecoinvent	3.8	3c5a2d44-0206-427c-b34e-3b871077bd40	Uranium-238	The CAS numbers are the same (24678-82-8); both name the same compartment.

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.
