At a press-conference today, Gen. Igor Valynkin, the head of the 12th Main Directorate of the Ministry of Defense, mentioned that Russia keeps its nuclear warhead production lines open as a way to ensure safety and reliability of nuclear warheads in the active arsenal - "We send old nuclear warheads for disassembly and disposal and get new ones from the industry."

Valynkin also said that there were two attempts to infiltrate nuclear storage facilities - one in 2002 and one in 2003, but neither was successful - the perpetrators were caught and handed over to the FSB.
