Radionuclide Retardation During Transport Through Fractured Granite |
| abstract |
Conclusions From this work it is apparent that sorption of radionuclides onto weathered fracture infill is likely to be a complex process although data trends may be presented as empirical relationships (e.g. Freundlich isotherms). Detailed studies of reaction mechanisms are in progress and indicate that, for even simple chemical species, sorption can be a complex function of reaction time, temperature, elemental concentration, concentration of competing ions and reaction direction. By use of simple models of groundwater flow, sorption data can be placed in a realistic geological context and results indicate that output curves resulting from fissure tracer experiments could be explained in terms of totally different retardation mechanisms. While various mechanisms might give similar retardation at short path lengths, more detailed information on mechanisms is required to justify extrapolation of data to the long pathlengths and timescales required in safety assessment and it is thus apparent that laboratory and in-situ studies are both essential and complementary in this field. |

Detailed studies of reaction mechanisms are in progress and indicate that, for even simple chemical species, sorption can be a complex function of reaction time, temperature, elemental concentration, concentration of competing ions and reaction direction. By use of simple models of groundwater flow, sorption data can be placed in a realistic geological context and results indicate that output curves resulting from fissure tracer experiments could be explained in terms of totally different retardation mechanisms. While various mechanisms might give similar retardation at short path lengths, more detailed information on mechanisms is required to justify extrapolation of data to the long pathlengths and timescales required in safety assessment and it is thus apparent that laboratory and in-situ studies are both essential and complementary in this field.</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">West, Julia M.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">MRS online proceedings library</subfield><subfield code="d">Warrendale, Pa. : MRS, 1998</subfield><subfield code="g">11(1981), 1 vom: Dez.</subfield><subfield code="w">(DE-627)57782046X</subfield><subfield code="w">(DE-600)2451008-7</subfield><subfield code="x">1946-4274</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:11</subfield><subfield code="g">year:1981</subfield><subfield code="g">number:1</subfield><subfield code="g">month:12</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://dx.doi.org/10.1557/PROC-11-811</subfield><subfield code="z">lizenzpflichtig</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_SPRINGER</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2005</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">11</subfield><subfield code="j">1981</subfield><subfield code="e">1</subfield><subfield code="c">12</subfield></datafield></record></collection>
