Russia: Five confirmed dead, three injured in blast at Arkhangelsk region MoD test site
Five testing researchers died and three were injured as a result of an explosion in a Ministry of Defence nuclear testing area in the northern Russian region of Arkhangelsk on August 8. Details of the incident were announced in Sarov on Sunday.
“Of course, the death of our employees is a bitter loss for the entire Institute, for the enterprise – the state Corporation Rosatom. The testing researchers associated with this activity, of course, are national heroes,” Director of All-Russian Scientific Research Institute of Experimental Physics (RFNC-VNIIEF) Valentin Kostyukov said.
Deputy head of the RFNC-VNIIEF Science Leader Alexander Chernyshev added that the incident was “an unpredictable scenario which emerged in reality.”
“We found that radioactive background increased twice and did not last more than an hour via direct measurements and its comparison. Neither our experts nor external experts registered any remaining radioactive contamination,” Chernyshev explained.
According to Rosatom, on August 8 the situation went out of control when the scientists were conducting engineering support of the isotopic power sources in a liquid propulsion system.
