I'm reading the Scientific American article on the Oklo reactor.

One of the statements is that U237 was produced, and that this
decays (after some time, and through some steps) to Bismuth.

What reaction produces U237 in a nuclear reactor?

Mostly two successive neutron captures by 235-U ,
the second striking the 236-U intermediate within
a time after its creation that is short compared to
its ~20-megayear half-life.
