The Beluga travels to the site of the Cogema outflow pipe with a banner that reads "Stop Radioactive Pollution. Save Our Seas" and Greenpeace activists take samples. Greenpeace divers discovered that Cogema's so-called cleaning operation had, in fact resulted in an enormous nuclear mess at the end of the pipe. Underwater films show that Cogema has built an infrastructure of pipes and barrels underwater, a small industrial site on the seabed. Cogema has been trying to cover upthe real impact of its operations and to remove the nuclear debris from the seafloor.
