Four people have been arrested after protesters blockaded access to the nuclear site at Hinkley Point in Bridgwater this morning [Friday].
Ten protesters paraded a banner saying "Nuclear Power - not worth the risk" and attempted to block access to staff to prevent further ground clearance work at the site.
If EDF, the energy company behind the plan, gets the go ahead to build it, the plant could be open by 2020.
The early morning blockade caused long tailbacks for scores of workers contracted in to perform maintenance work on the the existing reactors at Hinkley B.
EDF have signalled their intention to re-licence the reactor again in 2016.
Four people were arrested for wilfully obstructing the highway.
