Biosphere Dose Conversion Factor Percentiles for Radionuclides Identified as Being Potential Contributors to Dose After Ten Thousand Years
Two previous Analysis and Modeling Reports (AMRs) Civilian Radioactive Waste Management Systems Management and Operating Contractor (CRWMS M&O 2000a and CRWMS M&O 2000b) provided abstractions of the biosphere dose conversion factors (BDCFs) for those radionuclides determined (CRWMS M&O 1999a) to be of potential importance for the initial ten thousand years after closure of the repository. To continue predictions of dose beyond ten thousand years requires abstractions of the BDCFs for those additional radionuclides defined in CRWMS M&O 1999b to be of potential importance in this time domain. The radionuclides for which BDCFs were generated (CRWMS M&O 2000c) to address the time period out to a million years are {sup 210}Pb, {sup 226}Ra, {sup 230}Th, {sup 231}Pa, and {sup 242}Pu. The abstraction to be used in this calculation for providing as input to the Total System Performance Assessment (TSPA) code is the definition of the percentile points, at intervals of 5%, of the set of stochastic BDCF data for each radionuclide generated and reported in CRWMS M&O 2000c. Being based directly on the stochastic data the approach captures the uncertainty in the BDCF distributions.
