The Nuclear Reactors Buried in the Deep Sea

The Soviet Union used the waters east of Novaya Zemlya to dump reactors, spent nuclear fuel and solid radioactive waste from both the navy and the fleet of nuclear-powered civilian icebreakers. About 17,000 objects were dumped in the period from the late 1960s to the late 1980s. Most of the objects are metal containers with low- and medium level radioactive waste. The challenge today, though, are the reactors with high-level waste and spent uranium fuel, objects that will pose a serious threat to the marine environment for tens of thousands of years if nothing is done to secure them.

The reactors from the submarines K-11, K-19 and K-140, plus the entire submarine K-27 (in the Kara Sea) and spent uranium fuel from one of the old reactors of the Lenin-icebreaker have to be lifted and secured. Also, the submarine K-159 (in the Barents Sea) that sank north of Murmansk while being towed for decommissioning in 2003 have to be lifted from the seafloor, the experts conclude. A study report made for Rosatom and the European Commission has evaluated the costs of lifting all six objects, bringing them safely to a yard for decommissioning and securing the reactors for long-term storage. The estimated price-tag for all six will €278 millions, of which the K-159 is the most expensive with a cost of €57.5 millions. Unlike the submarines and reactors that are dumped in relatively shallow waters in the Kara Sea, the K-159 is at about 200 meters depth, and thus will be more difficult to lift.

Saving the Fisheries of Barents Sea from Nuclear Waste: the Andreeva Bay Case

A shipment of 14 containers with spent nuclear fuel from Andreeva Bay to Atomflot in Murmansk, Russia took place in December 2019 but it was paid by Norway.  Unloading the 40-years old spent uranium fuel elements from the rundown storage tanks and repacking them to transport containers came with a price-tag of 5 million kroner (€500 000), while the shipment from Andreeva Bay to Murmansk will cost additional 2,5 million kroner (€250 000).

The December 2019 shipment was the fourth that year, but the first one paid by Norway.  In Andreeva Bay, only 65 kilometers from the border to Norway, the Soviet navy packed away its lethal leftovers. Without too much thought for the costs of future clean up.  In Norway, like in Russia, the demand for action came out of fears for possible radioactive leakages that could have potentially negative impact on the important fisheries in the Barents Sea.  So far, isotopes contamination has only been discovered in the sediments in the near proximity off the shore and not further out in the bay.

Concerns of nuclear accidents and radioactive leakages are also why Norwegian authorities have granted hundres of millions kroner in aid to secure and clean up the site.  After 25 years of cooperation to improve the situation in Andreeva Bay, the Norwegian experts argue that direct financing of practical work is the best way to gain an insight into how Russia deals with the clean up.

By the end of Soviet times, in the late 1980s, a total of 22,000 spent nuclear fuel elements, equal to about 100 reactor cores from submarines, had accumulated at the run-down storage facilities. In addition came thousands of cubic meters of solid radioactive waste stored outdoor in rusty containers and hundreds of cubic meters of liquid radioactive waste in tanks.

The two first decades of international cooperation concentrated on improving the infrastructure. Buildings were erected to cover three concrete tanks holding the spent nuclear fuel, both to keep out rain and snow, but also to make sure the removal- and repacking work could take place in safe conditions.  The quay by the shore was rebuilt, a new special crane for lifting transport casks where put in place. Even a new on-purpose designed ship was built, paid by Italy.

In 2017, the first load of containers with spent nuclear fuel left Andreeva Bay towards Murmansk, from where it go by rail to Mayak, Russia’s reprocessing plant north of Chelyabinsk east of the Ural Mountains.  So far in 2019, three shipments paid by Russia and one shipment paid by Norway have left Andreeva Bay.  “25% of the original amount of spent nuclear fuel is now removed,” says Per-Einar Fiskebeck…

The remaining waste, tank 3A holds numerous rusty, partly destroyed steel pipes where concrete of poor quality was filled in the space between. Some of those fuel assemblies are stuck in the canisters, while some of the canisters are stuck in the cells.  This is high level nuclear waste with radiation levels close to the uranium fuel comparable to the melted fuel rods inside the ill-fated Chernobyl reactor. 

Another groundbreaking milestone in the clean up work took place earlier this fall when the retrieval of six abandoned, highly radioactive spent nuclear fuel assemblies from the bottom of Building No. 5 were successfully completed.  Building No. 5 is a former pool storage, where several elements fell to the floor following a water-leakages in 1982. Traces of uranium and other radionuclides remained in the sludge at the bottom of the pool.

First Floating Nuclear Plant

Russian State Expert Examination Board (Glavgosexpertiza) has announced that the floating nuclear power plant  meets construction standards. The authority said on 9 December it had approved the project in Russia’s northernmost city of Pevek that is being funded by Rosenergoatom, the nuclear power plant operator subsidiary of Rosatom.  Currently moored at the Baltiysky Zavod shipyard in Saint Petersburg, Akademik Lomonosov houses two 35 MW KLT-40S nuclear reactors, similar to those used in Russia’s nuclear-powered ice breakers

The plant is intended to replace the outgoing capacity of the Bilibino nuclear power plant in the Chukotka district. The first Bilibino unit is scheduled to be shut down in 2019 and the whole plant will be shut down in 2021.

Excerpts from First Floating Nuclear Power Plant Akademik Lomonosov, Nuclear News, Jan. 11, 2018

Environmental groups like Bellona are not convineced that the plant is safe.  According to Bellona,   in August 2017, Rosatom responded to pressure from the Norwegian Ministry of Foreign Affairs to delay fueling the plant with its uranium fuel until it had cleared its coast…It has now apparently been settled that the Akademik Lomonosov will be loaded at Atomflot, Russia’s nuclear icebreaker in Murmansk, by fuel that will arrive separately…The overall cost for the Academic Lomonosov, both the plant and infrastructure for its Far Eastern port, are expected to top $530 million – which is almost four times as expensive as it was projected to be in 2006.  In the end, that may weigh in on the cheap side. The costs of decommissioning the vessel have not yet been weighed, nor have the costs of cleaning up a nuclear accident on a stretch of land as remote as the Kamchatka Peninsula.
