Argonne model

As a consequence, corporations operating PUREX plants have been using sophisticated process simulation codes, including the PAREX code in France (45-47), SpeedUp (Aspen Plus) in the UK (48), and SIMPSEX code in India (49-51). Argonne Model for Universal Solvent Extraction (AMUSE) code in the United States was contrived not only for PUREX, but for UREX+ processes (52), which will be mentioned later. In Japan, similar efforts have also been made (53-55). [Pg.6]

MORROW It seems that one of the essential features of this approach is that somewhere in the beginning you had to have a model dealing with transport and deposition. You cited the Argonne model. How does it take into account climatology, let s say. Does it use a historic average circumstance for that area An average wind direction An average wind velocity ... [Pg.459]

MORROW Then they must also be able to provide how much fluctuation would be implicit in such a model, probably. Is each region going to have to develop such a model You can t take the Argonne model, if it has topographic information and such historic information and generalize. [Pg.459]

Fet us now confront the EOS predicted by the phenomenological TBF and the microscopic one. In both cases the BHF approximation has been adopted with same two-body force (Argonne uis). In the left panel of Fig. 4 we display the equation of state both for symmetric matter (lower curves) and pure neutron matter (upper curves). We show results obtained for several cases, i.e., i) only two-body forces are included (dotted lines), ii) TBF implemented within the phenomenological Urbana IX model (dashed lines), and iii) TBF treated within... [Pg.118]

To quantify this treatment of migration as influenced by kinetics, a model has been developed in which instantaneous or local equilibrium is not assumed. The model is called the Argonne Dispersion Code (ARDISC) ( ). In the model, adsorption and desorption are treated independently and the rates for adsorption and desorption are taken into account. The model treats one dimensional flow and assumes a constant velocity of solution through a uniform homogeneous media. [Pg.168]

Exotic atomic nuclei may be described as structures than do not occur in nature, but are produced in collisions. These nuclei have abundances of neurons and protons that are quite different from the natural nuclei. In 1949, M.G, Mayer (Argonne National Laboratory) and J.H.D. Jensen (University of Heidelberg) introduced a sphencal-shell model of die nucleus. The model, however, did not meet the requirements and restrains imposed by quantum mechanics and the Pauli exclusion principle, Hamilton (Vanderbilt University) and Maruhn (University of Frankfurt) reported on additional research of exotic atomic nuclei in a paper published in mid-1986 (see reference listedi. In addition to the aforementioned spherical model, there are several other fundamental shapes, including other geometric shapes with three mutually peipendicular axes—prolate spheroid (football shape), oblate spheroid (discus shape), and triaxial nucleus (all axes unequal). [Pg.1211]

The Argonne experimental results [69] were consistent with an Arrhenius emperature dependence of the cuprous-cupric rate, though the uncertainties vere substantial regarding this conclusion. We only performed simulations at me temperature and so did not check whether the model predicts a strictly Vrrhenius behavior. The most obvious case in which the model would lead to... [Pg.382]

As with Argonne, we had a project related to fuel cell technology with Sandia. Although the technology associated with the project was successful, Dow made a business decision to exit the fuel cell business and so the project was never completed. We have also had a very successful project on materials modeling. Here, Dow has a business focus, but the basic technology being developed can be... [Pg.90]

Time-resolved X-ray scattering data are presented for three different carbons that w ere activated in situ in the beamline at the Advanced Photon Souree at the Argonne National Laboratory in Argonne, IL, USA. The resultant data exhibit vai ied behavior, depending on the carbon type. The data suggest a dynamic porosity development mechanism. A net population balance model of pores within a particular size range may explain these observations. [Pg.59]

Several options are available in FLOTRAN for representing fractured media. The equivalent continuum model (ECM) formulation represents fracture and matrix continua as an equivalent single continuum. Two distinct forms of dual continuum models also are available, defined in terms of connectivity of the matrix. These models are the dual continuum connected matrix (DCCM) and the dual continuum disconnected matrix (DCDM) options. A parallel version of the code, PFLOTRAN, has been developed based on the PETSC parallel library at Argonne National Laboratory. [Pg.2307]
