CONSEQUENCE ANALYSIS<br />

been provided in the final Statement. For example, the exposure that might result to the<br />

workforce from a canister drop down a mine shaft followed by a rupture <strong>of</strong> the canister was<br />

developed and presented in Section 5.4.<br />

By and large, protection <strong>of</strong> the workforce is stressed in other documentation such as<br />

Safety Analysis Reports for specific plants.<br />

The use <strong>of</strong> adsorption coefficients from one set <strong>of</strong> Hanford subsoils, measured under<br />

laboratory conditions, is not an adequate basis for scoping the effect <strong>of</strong> adsorption. There<br />

are some substantial differences between the adsorption coefficients <strong>of</strong> the Hanford subsoil<br />

and <strong>of</strong> those given on page K-20 <strong>of</strong> the <strong>Waste</strong> Isolation Pilot Plant EIS (DOE/EIS-0026-D), for<br />

example. (113-EPA)<br />

Response<br />

At the time the work was done the Hanford, or typical western desert subsoil sorption<br />

data was the only set <strong>of</strong> data available for reference.<br />

One commenter questioned the definition <strong>of</strong> risk as "the sum product <strong>of</strong> the magnitude<br />

<strong>of</strong> losses.and the probability that the losses will occur." A tendency exists for aversion<br />

<strong>of</strong> high consequence accidents, which would imply a valuation other than a strict<br />

probability-consequence product. (113-EPA)<br />

Response<br />

The final Statement refers to the product <strong>of</strong> probability and consequences (or societal<br />

losses) or mathematical expectation <strong>of</strong> societal risk. This does not include "risk aversion"<br />

which is likely to vary from individual to individual. Where first introduced in the text<br />

the aspect "non-linearity <strong>of</strong> risk aversion" is addressed.<br />

Consequence analysis for any release is the estimation <strong>of</strong> the effect <strong>of</strong> that release.<br />

It is not restricted to postulated worst cases. (113-EPA)
