3. DESCRIPTION OF PROGRAM OR FUNCTION

NUTRAN is a system of four computer programs for calculating the dose to humans from radionuclides carried out of deep geologic nuclear waste repositories by ground water. NUTRAN is composed of the FORTRAN programs - ORIGEN1 and BIODOSE and the PL/I programs - WASTE and PLOT. ORIGEN1, developed by Oak Ridge National Laboratory, generates an inventory of radionuclides as a function of time; BIODOSE computes the doses to humans which result from any releases of radioactivity into the biosphere. WASTE models the release of radionuclides from a repository and their transport in the subsurface, and PLOT combines the results of BIODOSE and WASTE - dose per MWe-yr released and releases in units of MWe-yr of waste - to obtain doses and generate dose plots. The ORIGEN1 program developed by ORNL is not included.

4. METHOD OF SOLUTION

The NUTRAN model incorporates the following features: refilling of the repository cavity with water; leaching of the waste matrix; dissolution of the radioactive elements in the waste; transport of waste by ground water through the repository, surrounding strata, and adjacent aquifers; withdrawal of contaminated ground water through wells; transport of waste in surface waters and associated ecosystems; and human exposure and dose mechanisms. A three-dimensional ground water flow field is modeled as a network of one-dimensional flow paths or "stream tubes". The stream tube approach allows a relatively straightforward representation of small discontinuities (e.g. faults, boreholes), avoiding the difficulties which are encountered in solving time-dependent solute migration problems by finite-element or finite-difference methods. For each stream tube, nuclide transport is solved explicitly by a Green's function (impulse response) approach. The biosphere transport is modeled by a system of sediment, water, and soil compartments. Radionuclide concentrations in these compartments are used to compute doses to humans.
