A dated British term for electromagnetic pulse (EMP) -- the burst of electromagnetic energy from a nuclear detonation that can disable electronic systems across a wide area. The term was used in UK civil defense and military planning contexts during the Cold War era. It is now largely replaced by the standard international acronym EMP in both technical and popular usage.
Nuclear code refers to the classified authorization codes used by military and government officials to authenticate orders for launching nuclear weapons. In the US system, these codes are part of the 'nuclear football' protocol that travels with the President at all times. In everyday conversation the phrase often gets used dramatically to describe any heavily guarded secret or impossibly secure password — if your WiFi password is called a 'nuclear code,' someone's being a bit theatrical.
