58 Figure 5.3.1 Probability of occurrence of excess water volumes in the Jabiluka Total Containment Zone over the life of the mine for the storage capacity specified by ERA A model for assessing the radiation dose resulting from discharges of radionuclides from Jabiluka will be different from the Ranger model, principally in the radionuclide dispersion part of the model. However, the difference will be relatively small and the Ranger model has been applied here. The dose estimates arising from the excess volumes predicted by the Monte Carlo analysis of the Jabiluka water management proposed by ERA lie in the range 0 to 27 Sv. These estimates take into account that runoff from the ore stockpile only contributes 1% of the total water flowing from the TCZ to the retention pond. The probability of occurrence of these doses over the 30 year life of the mine are presented in figure 5.3.2.
