Foyle's War: The Eternity Ring question

There really were no secrets about either the uranium or plutonium fission weapons that the Soviets didn't already possess, courtesy of Klaus Fuchs.

Happily, there's an in-story reason why that might not impede the Eternity Ring from carrying out its nuclear spying in the UK, which is SPOILER ROT 13 vg qbrf abg rkvfg.

It doesn't hurt that Fuchs was also passing along information about the U.S. bomb program to the British, which could be deliciously ironic.
