Russian nuclear scientists arrested for trying to use one of Russia's most powerful supercomputers to mine Bitcoins

Russian security officers have arrested several scientists working at a top-secret Russian nuclear warhead facility for allegedly mining crypto-currencies.

The suspects had tried to use one of Russia's most powerful supercomputers to mine Bitcoins, media reports say.

The Federal Nuclear Centre in Sarov, western Russia, is a restricted area.

The centre's press service said: "There has been an unsanctioned attempt to use computer facilities for private purposes including so-called mining."

The supercomputer was not supposed to be connected to the internet - to prevent intrusion - and once the scientists attempted to do so, the nuclear centre's security department was alerted. They were handed over to the Federal Security Service (FSB), the Russian news service Mash says.

"As far as we are aware, a criminal case has been launched against them," the press service told Interfax news agency.

About the town

In the Cold War the USSR's first nuclear bomb was produced at Sarov, during Joseph Stalin's rule.

The top-secret town was not even marked on Soviet maps and special permits are still required for Russians to visit it.

There have been reports of some other industrial facilities in Russia being used for crypto-mining, and one businessman reportedly bought two power stations for the activity.
