AREST model description

“…These results are all compared against results from UCB (Sadeghi et al 1990). Figure A.7 shows the effect of shared solubilities for the plutonium nuclides and is compared against the UCB results (Sadeghi et al 1990, Figure 1).…”

“…These results are all compared against results from UCB (Sadeghi et al 1990). Figure A.7 shows the effect of shared solubilities for the plutonium nuclides and is compared against the UCB results (Sadeghi et al 1990, Figure 1). Figure A.8 shows a good comparison with published results (Sadeghi et al 1990, Figure 7) for the alteration-limited release model assuming a "wet-drip" water contact mode.…”

“…Figure A.7 shows the effect of shared solubilities for the plutonium nuclides and is compared against the UCB results (Sadeghi et al 1990, Figure 1). Figure A.8 shows a good comparison with published results (Sadeghi et al 1990, Figure 7) for the alteration-limited release model assuming a "wet-drip" water contact mode. Minor discrepancies occur in the results for the inventory-limited/gap release model shown in Figure A.9.…”

“…Minor discrepancies occur in the results for the inventory-limited/gap release model shown in Figure A.9. The AREST results are compared to Figure 6 from Sadeghi et al 1990. The differences occur in the estimation of the void volume for the two models.…”

Equations for predicting release rates for waste packages in unsaturated tuff

“…Some of the equations are newly derived for this report, others are restated from earlier work. Release rates have been calculated for key radionuclides in a companion report [Sadeghi et al 1990a]. We consider gaseous releases separately [Light ei al.…”
