Before the 1990s, the Severka was used to move spent nuclear fuel in Soviet-produced shipping containers of the type TK-12 from Andreyeva Bay – the former naval base in the northwestern part of the Kola Peninsula – to a transshipment site in Murmansk dubbed Area SRZ-35. There, not far from the grounds of Atomflot, Russia’s nuclear fleet operator, the spent nuclear fuel was reloaded into railway cars to be shipped off to the reprocessing plant Mayak in the Urals.
The Severka was also equipped with special tanks for shipments of liquid radioactive waste.
Information about the Severka’s sinking appeared Monday in a Russian-language blog which said the vessel had gone under on May 24th while moored at a wharf operated by Shiprepairing Yard No. 10 in Alexandrovsk.
Alexandrovsk is a restricted-access area called in Russian by the acronym of ZATO, which stands for “closed administrative territorial entities” – or closed cities dealing with secretive scientific or military procedures.
Disturbingly, the location where the vessel, which is presumed to be still contaminated as a result of years of transporting spent nuclear fuel and radioactive waste, reportedly sank is only 60 kilometres off the large city of Murmansk.
Both the management of the Alexandrovsk yard and Murmansk authorities decline to comment on the report. Likewise, no information has yet been offered by officials in the Northern Fleet.
The Severka was built in Hungary in 1957 and was later commissioned by the Northern Fleet. In 1978, its service as a support vessel was discontinued and it was retrofitted for the transportation of spent nuclear fuel from Andreyeva Bay to Murmansk. Since 1993, the Severka has been out of commission.
After years of various operations involving transportation and transshipment of spent nuclear fuel, the Severka itself now falls into the category of radioactive waste. According to data available, the most severely contaminated sections were, however, removed from the vessel by 2007.
“Now that this vessel has been scheduled for decommissioning, no [spent nuclear fuel] could be there, not according to any of the existing rules,” said Bellona Murmansk head Andrei Zolotkov.
The same, he said, happens with nuclear submarines, where spent nuclear fuel is first unloaded before the submarines are sent for dismantlement.
“Because the Severka was used for a long time to transport [spent nuclear fuel] in old containers, it is quite possible that there remain radioactively contaminated areas and equipment – or solid radioactive waste – on board the vessel. One could not rule out small quantities of low-level liquid radioactive waste, either. If the vessel did indeed sink, this is evidence of irresponsibility and negligence on the part of specialists in charge of decommissioning the Severka,” Zolotkov concluded.
Bellona is watching the situation for further developments and will be posting updates as they become available.
Recent attacks on Ukraine’s Zaporizhzhia nuclear power plant "mark the beginning of a new and gravely dangerous front of the war," the UN atomic agency's director general said last week.
After years of inaction, Germany is working on its Carbon Management Strategy to resolve how CCS can play a role in climate action in industry. At the end of February, the Federal Ministry for Economic Affairs and Climate Action published first key points and a proposal to amend the law Kohlenstoffdioxid Speicherungsgesetz (KSpG). Bellona Deutschland, who was actively involved in the previous stakeholder dialogue submitted a statement in the association hearing.
In the midst of a global discussion on whether natural gas should be used as a transitional fuel and whether emissions from its extraction, production, transport and use are significantly less than those from other fossil fuels, Russia has developed ambitious plans to increase its own production of liquified natural gas (LNG) in the Arctic – a region with 75% of proven gas reserves in Russia – to raise its share in the international gas trade.
