<str<strong>on</strong>g>The</str<strong>on</strong>g>se four framework areas were competed through an Official Journal of European Uni<strong>on</strong> (OJEU) process in 2008. Although<br />
all four areas involve waste management, Waste Processing and Material Characterisati<strong>on</strong> specifically deal with Higher Activity<br />
Waste (HAW) waste management issues. <str<strong>on</strong>g>The</str<strong>on</strong>g> Waste Processing area was awarded to three groups: (i) Nati<strong>on</strong>al Nuclear Laboratory<br />
(NNL), (ii) C<strong>on</strong>sortium led by Hyder C<strong>on</strong>sulting Ltd, and (iii) C<strong>on</strong>sortium led by UKAEA Ltd. <str<strong>on</strong>g>The</str<strong>on</strong>g> Material Characterisati<strong>on</strong><br />
area was awarded to three groups: (i) NNL, (ii) Serco, and (iii) C<strong>on</strong>sortium led by UKAEA Ltd.<br />
5) SIDE RADWASTE TREATMENT FACILITIES FOR THE WESTINGHOUSE AP1000 PROJECTS IN SANMEN<br />
UND HAIYANG, PR CHINA - 16410<br />
Andreas Roth, Hansa Projekt Anlagentechnik GmbH (Germany); John Merrell, Westinghouse Electric Co Uk Ltd (UK)<br />
Currently two blocks of the Westinghouse AP1000 pressurized water-reactor are built at the sites Sanmen und Haiyang in the<br />
Peoples Republic of China. 6-8 blocks of the reactor type will be operated during ultimate installati<strong>on</strong> at each side.<br />
<str<strong>on</strong>g>The</str<strong>on</strong>g> waste treatment c<strong>on</strong>cept in the US is orientated towards external c<strong>on</strong>diti<strong>on</strong>ing service and therefore the Westinghouse plan<br />
of c<strong>on</strong>cept for the AP1000 doesnt c<strong>on</strong>tain any other waste treatment facilities for waste beside the power plants water treatment.<br />
Loading units for transport to external service providers are planned instead of that.<br />
<str<strong>on</strong>g>The</str<strong>on</strong>g>re is no essential infrastructure of potential service providers in the PR China and therefore a coherent waste treatment c<strong>on</strong>cept<br />
was needed for the building license.<br />
Because of that Hansa Projekt Anlagentechnik GmbH developed a plan of c<strong>on</strong>cept for building waste treatment centers at the<br />
different sides in cooperati<strong>on</strong> with the Shanghai Nuclear Engineering and Design Institute.<br />
6) STATISTICAL MODELLING APPLIED TO THE CONTENTS OF WASTE DRUMS - 16085<br />
Richard Bull, Ian Pearman, Nuvia Limited (UK)<br />
Gamma spectrometry is widely used to determine the radioactive c<strong>on</strong>tent of waste drums. However, the results of such surveys<br />
often result in large numbers of limit-of-detecti<strong>on</strong> (LOD) results. In this paper we will show how simple statistical methods can be<br />
used to obtain useful informati<strong>on</strong> <strong>on</strong> the average drum activities, even in these unfavourable circumstances.<br />
Results from measurements <strong>on</strong> 60Co, 152Eu, 154Eu activities in drums of waste from decommissi<strong>on</strong>ing of the GLEEP reactor<br />
suggest that these activities are lognormally distributed with geometric standard deviati<strong>on</strong>s (GSD) ranging from 3-4. This statistical<br />
model can be used to extract informati<strong>on</strong> from 235U, 234mPa and 234Th datasets which show <strong>on</strong>ly LOD activity results. In a<br />
repository of N drums, each with activity
