The Sarov Federal Nuclear Centre, in Nizhny Novgorod region, has been menaced for two weeks by fires raging in a neighbouring nature park in Mordovia republic.Earlier, he had declared that all the explosive materials have been removed as wildfires were approaching the former secret township of Arazamas-16, where first Soviet hydrogen bomb was fabricated. Over 3,000 people, four helicopters, four planes and 30 fire trucks were involved in putting out wildfires in proximity to the Sarov nuclear centre.
