Land remediationA programme of work is underway to survey the land atHarwell for any contamination from chemicals andradioactivity. Like many sites, which have been in industrialuse, there are some areas which have been subject tocontamination. Through the survey programme suspectareas are identified, investigated and remediated asappropriate. There are some areas of the site, which havebeen used for disposal of chemicals, beryllium, and lowlevels of radioactivity. In particular a major remediation of aseven-hectare area, known as the Southern Storage Area,has been completed. Known chemical and berylliumdisposal pits have been removed and all the land checkedand proven to be clean. During the work munitions arisingfrom the RAF use of the site were also removed.Further chemical disposal pits in what is known as theWestern Storage Area will be removed. These pits wereused for the disposal of chemicals including chlorinatedhydrocarbons, which have entered the groundwater belowthe site. A “pump and treat” plant is in operation to recoverchlorinated hydrocarbons from the aquifer and prevent anyfurther spread of contamination.Plant for removal of chlorinated hydrocarbons from groundwaterAs the decommissioning work on the nuclear licensed siteprogresses the land and buildings are being thoroughlysurveyed to ensure that there is no residual radioactivity.This will allow a substantial part of the eastern end of thesite to be delicensed (i.e removed from the controls of thenuclear site licence) and the land made available for otheruses.Beryllium disposal pit after removal of waste showing clay linerMajor new site utilities installedin 2003Property managementThe land and buildings owned by UKAEA form part of theHarwell Chilton Campus. Together with the separate freeholdsof Rutherford Appleton Laboratory and National RadiologicalProtection Board the campus is a major centre for employmentwith around 4000 people working here. Many of the existingbuildings on the site are made available by UKAEA to tenantorganisations. A number of these organisations were spun offfrom UKAEA and new businesses are being attracted to thesite. There is an Innovation Centre designed for start-upbusinesses and a range of other businesses have moved toHarwell. The Medical Research Council is expanding andbuilding the Mary Lyon Centre to support the Genome project.A major new facility called the Diamond Light Source is beingbuilt adjacent to the Rutherford Appleton Laboratory, fundedby Government and the Wellcome Trust.The Diamond Light Source will have many applications but willbe particularly suitable for the examination of the structure ofbiological materials. In the past Harwell has been associatedwith nuclear research and development but the newdevelopments around the campus will place it at the forefrontof bioscience research. The scale and reputation of thecampus means it is well placed for further new development.Evolution of UKAEA Harwell 4

A smallernuclear site will remain for some yearsuntil all the decommissioning iscomplete and it is possible to disposeof the remaining radioactive wastes.The reduction of the nuclear site isallowing new development around theHarwell campus, which will ensure thatit continues to grow as a major centrefor science and technology.
