Russia indicates rocket engine exploded in test of mini nuclear reactor | World news | The Guardian
Je fais donc un post séparé pour cet autre accident survenu en #Russie
Russian scientists have indicated that they were working on miniaturised sources of nuclear energy when a rocket engine exploded last week, increasing scrutiny of the possibility that the accident occurred while testing an experimental cruise missile powered by a small reactor.
The explosion last Thursday at a military testing ground in Russia’s Arkhangelsk region killed at least five people and caused radiation readings in neighbouring cities to spike to 20 times their normal level for half an hour.
Russia’s defence ministry said the explosion had taken place during testing of a rocket engine, but the country’s nuclear agency, Rosatom, later confirmed that several of its employees had been killed during testing of an “isotope power source in a liquid propulsion system”.
David Cullen, the director of the Nuclear Information Service in the UK, said on Monday that the view among independent experts was that the explosion appeared to have been caused by the failure of an experimental nuclear-powered cruise missile known in Russia as the 9M730 Burevestnik and by Nato as the SSC-X-9 Skyfall.
