ELI5- How large can one nuclear bomb get?

481 views

We seem to have hit the limit with tests such as Tsar Bomba, but that is only because it’s not reasonable or necessary to push it any farther. But I’m wondering what the theoretical limit is. Is there a limit for a single device in which size would make an effective reaction impossible?

We can make them as big as we want. The teller-ulam design allows us to chain larger and larger fusion bombs as much as we want.

The only real “limit” is that big nukes are less effective than a few smaller nukes.
