02:55 Experimantal Validation of UTDefect: Scattering in Anisotropic Media and Near-field Behavior
UTDefect utvecklades samtidigt. Motivering av detta arbete och detaljerad beskrivning av UTDefect finns i Boström (1997 och 2000). Avsikten med föreliggande projekt har varit att bygga vidare på de initiala ... spricka i en anisotrop komponent, samt en nyutvecklad modell av ett närfält. I det sista fallet är komponenten isotrop. För det första delmålet användes ett testblock av kisel monokristall. I blocket...

2017:15 Radionuclide release rates associated with bounding cases featuring relatively early canister failures in a spent fuel repository
and data sources are summarized in this section. We considered 22 radionuclides (C-14, Cs-135, I-129, Nb-94, Ni-59, Np-237, Pb-210, Pu-238, Pu-239, Pu-240, Pu-242, Ra-226, Rn-222, Se-79, Tc-99, Th-230 ... derives from the decay of the Pu-241 and Am-241 parents. A fraction of the inventory of C-14, Cs-135, I-129, Se-79, Tc-99, Ni-59, and Nb-94 was assumed to be released into the in-canister water immediately...

2002:11 National plan for achieving the objectives of the OSPAR strategy with regard to radioactive substances
OSPAR-konventionen för skyddet av den marina miljön i Nordostatlanten trädde i kraft 1998. Konventionen har ratificerats av 16 länder samt EU. Vid OSPAR:s kommissionsmöte i Sintra 1998, kom miljöministrarna överens ... terna av dessa ämnen i den marina miljön ska vara nära noll för artificiella radioak- tiva ämnen år 2020, halter i miljön orsakade av historiska utsläpp undantagna. Som ett led i att uppnå strategins mål...
