Nuclear weapons convoy dangers

Convoy 7 May 2011

Convoys in town 7 May 2011

The Ministry Of Defence (MOD) says there is little risk of a nuclear detonation during transport, but in an accident the highly volatile “conventional” explosive could be set off, causing the warhead to ‘jet’ plutonium. It estimates that, in a serious accident a circle some 600 yards in radius would be affected by blast and fragments of explosives. Even more problematic than the explosion itself would be its effect in dispersing alpha emitting plutonium and uranium particles down wind for miles. Alpha particles emitted by plutonium are not a serious risk if they remain outside the body, but if particles are ingested or inhaled they can cause cancer.

Nuclear weapons convoys often pass close to or even through large towns. It would be impossible to evacuate heavily populated areas on the routes in time to avoid the potential consequences of a traffic accident involving a nuclear warhead. MOD accident guidelines do not explain whether traffic would be quarantined, sent on its way or gridlocked in the contaminated zone.

Nuclear weapons convoys and Local Authorities

Local Authority Emergency Planning Officers have been given guidance (called the Local Authority & Emergency Services Information) about how to respond to any emergency arising from the passage of convoys. Local police are informed when a convoy is due to pass through their area, but not Fire Brigades.

Nukewatch Policy

We think that it is very important that Nukewatch continues to monitor the safety of UK nuclear warhead convoys, and that Convoy dangers are highlighted to the general public and those along its routes.

But we still think it's important that Nukewatch is not seen to be helping potential terrorists. So we do not put technical information on the websites such as vehicle number plates and short break locations in lay-bys. We only put out convoy movements in advance to our own network. This also means that we would not alert the media in advance, except to contact known and trusted journalists who might come along to report a convoy passing.
