Hazard indices generally neglect major confinement features such as the waste concen-<br />

tration (Hill 1977, Lash 1976), release mechanisms and dynamics (de Marsily 1977), and<br />

aspects <strong>of</strong> the food chain pathways. The hazard indices for the most part do not character-<br />

ize the population exposures associated with conceivable natural and man-induced disruptive<br />

events--the key aspects <strong>of</strong> a risk assessment.<br />

3.4.2 Consequence Analysis and Risk Assessment<br />

Consequence analysis is the estimation <strong>of</strong> the effects <strong>of</strong> postulated accidental releases<br />

<strong>of</strong> radionuclides. Risk assessment is the calculation <strong>of</strong> the consequences <strong>of</strong> the spectra <strong>of</strong><br />

possible accidental releases multiplied by their probabilities and summed to give a total<br />

risk. In this sense, the EIS does not present a complete risk assessment. The technique<br />

for such an assessment is still under develoment.<br />
