The two barges involved in the August radiation accident in the White Sea are being towed to a radioactive waste storage site on the Kola Peninsula. It is not known whether they hold the reactor responsible for the explosion and short burst of radiation measured in Severodvinsk.
The United States government has concluded that the incident was pretty much as has been speculated, a nuclear accident of some sort as a nuclear-powered missile was being recovered. Deputy Assistant Secretary of State Thomas G. DiNanno told a United Nations committee on October 10 that this was the US conclusion, but it was only two sentences.
The United States has determined that the explosion near Nenoksa, Russia, was the result of a nuclear reaction that occurred during the recovery of a Russian nuclear-powered cruise missile. The missile remained on the bed of the White Sea since its failed test early last year, in close proximity to a major population center.
Nothing to indicate what kind of nuclear reaction or how the United States knows this. The news is that they believe the failed test was in early 2018. The nuclear reaction was most likely a criticality incident, but we still don’t know enough about the reactor to speculate much about that. It’s possible that the government has overhead photos of the test or the recovery, perhaps alerted by someone in Russia who knew the schedules.
