Radioactive pollution is increasing at Britain’s nuclear bases

Radioactive air emissions have been increasing year-on-year at Coulport one of Britain’s nuclear submarine bases in Scotland. This development is of some concern as it would lead to increased health risks wherever the emissions were inhaled. 

Investigations by The Ferret and The National newspaper found that emissions of radioactive tritiated water vapour had doubled at the Royal Navy’s nuclear weapons storage depot at Coulport on Loch Long between 2018 and 2023. According to the Scottish Pollution Release Inventory, tritiated water vapour emissions at Coulport were 1.7 billion becquerels (units of radioactivity) in 2018, rising steadily to 4.2 billion units in 2023. Tritiated water vapour is  harmful when inhaled, ingested or absorbed through the skin as its radiation causes cancer and cardiovascular diseases including strokes.

The investigation also found that eight miles from Coulport at Faslane, where Britain’s nuclear submarines are based, tritiated water containing over 50 billion units of radioactivity had been dumped into the Gareloch. The level of dumping peaked in 2020, when 16.6 billion units were discharged. 

The Ferret noted that in 2019,  the Scottish Environment Protection Agency (SEPA) “changed the rules to allow certain tritium-contaminated effluents from nuclear submarines at Faslane to be discharged into the Gareloch.” Both SEPA and the MoD claim these emissions are within official safety limits.

However Dr Ian Fairlie, CND’s science advisor, states that these limits are unreliable, as official estimated doses from tritium contain “large uncertainties.”

CND General Secretary Sophie Bolt said: 

“From faulty nuclear-armed subs on dangerously extended patrols to crumbling nuclear waste sites, Britain’s nuclear industry is putting us all at great risk. Instead of enforcing the highest levels of environmental standards, the government is just redefining what ‘acceptable risk’ means. All so it can allow the dumping of radioactive water, putting local people at greater risk of cancer. This is beyond reckless. It’s time to scrap Trident and its replacement, and decommission the nuclear industry.”
