The Legacy of Past Energy Choices

          On the day that the UK Government gave the go ahead for the building of the twin unit nuclear power station at Hinkley Point members and friends of Pembrokeshire South East Energy Group (PSEEG) welcomed Tim Deere-Jones to their September meeting.

          Tim, as an independent marine researcher/consultant, has a particular interests in marine radioactivity. He carries out studies for many interested parties, including Ireland a nuclear free country.

          He started by giving the history of events concerning nuclear industry regulation. In 1952 there were no studies of the behaviour of radioactivity in the marine and coastal environments. Environmental monitoring was confined to near site investigations and the nuclear orthodoxy was that any problems would be from the consumption of seafoods.

          Later it was realised that radioactive nuclides could be transported long distances by sea currents. The nuclides from Sellafield have a very distinctive marker and this proved useful in seeing just how far these travel. At the moment only 5 of the 60 discharged nuclides are checked for.

          In 1987/88 Dyfed County Council asked him to carry out a survey of the coast in relation to this problem. While at the mouth of the river Teifi the results showed near normal readings, in the centre of Cardigan the readings had increased, at the salt marches they were higher again and radioactive nuclides were found as far inland as Newcastle Emlyn 10 miles from the sea. The reason for these increases was due to the nuclides attaching to finer sediments. There are also sea to land transfers which occur for a variety of reasons. In Towyn in 1990 flooding was the cause of increased nuclide rates. Wind, rain and human activity are other causes of increase.

          Tim then showed a series of maps. The Irish Sea temperature charts showed clearly a large number of currents. The discharge from Sellafield is taken north along the coast to Scotland, across the Irish Sea, south towards Cork then east along the south coast of the Bristol Channel before coming back along the Welsh coast.

          A sedimentation map then showed the areas of greatest sedimentation the Gwent levels and the Burry Inlet. As seen before, finer sediment holds the most radioactive nuclides.

          Tim finished his talk be pointing out that whilest individuals and groups interested in gathering data had to fund themselves, other countries for example Germany, France and Sweden were funded by their governments so that they could provide empirical evidence that could be fed into decisions.

          After many interesting questions Tim was thanked for his highly interesting and instructive talk by the Chair. During refreshments the discussion continued.
