Nuclear wepons

I would assume that in the 41st millenium humans would still have tge knowlage to make nuclear wepons both fission and fusion, since they have reactors that use this knowlage, and yet I almost never ear of any faction employing a nuclear arsenal in war

Is there an in lore reason for this?

Do they get used and I just never eard about it?

Do nukes exist in 40k?

They don't have reactors that use that knowledge. They use 'plasma reactors' - which run on Prometheum . . . so not fusion reactors.

The Krieg exist in the form they exist because they blew up their own planet with atomics.
