Andreev Bay Nuclear Accident: Introduction

When the pool in Building #5 started leaking in February 1982, someone's first idea was to pour in twenty sacks of flour. The theory was that dough would seal the cracks. It did not. That improvisation set the tone for everything that followed at Andreev Bay, a Soviet naval radioactive waste repository on the Kola Peninsula, 55 kilometers northwest of Murmansk and 60 kilometers from the Norwegian border. Over the next seven years, approximately 700,000 tonnes of highly radioactive water drained into the Barents Sea, workers fell into pools of irradiated water, and sailors used ordinary shovels to handle spent nuclear fuel that triggered spontaneous chain reactions glowing blue-green with Cherenkov radiation.

Soviet naval base 569 at Andreev Bay, on the western shore of the Zapadnaya Litsa inlet, entered service in 1961 as a repository for spent nuclear fuel from the Northern Fleet's submarine reactors. Building #5 housed two pools, each 60 meters long, 3 meters wide, and 6 meters dee...

The right-hand pool in Building #5 began leaking in February 1982. Inspecting the cracks required diving into the pool, which was impossible: gamma radiation levels near the submerged drums reached 17,000 roentgens per hour, a dose that would kill a person in minutes. After the f...

The cleanup, which ran from 1983 to 1989, involved approximately 1,000 people working in conditions that no safety protocol had anticipated. Workers cut windows into the protective covers with welding torches so they could lower grabbing devices to retrieve drums from the pool fl...

Perhaps the most chilling detail of the cleanup came during the transfer of fuel drums from Building #5 to dry storage containers. The containers, three underground steel cylinders each 18 meters in diameter, had originally been designed as water filtration structures. After bein...
