occur once per year due to improperly closed waste packages and result in a 70-yr accumu-<br />

lated dose to the maximum-exposed individual <strong>of</strong> 3 x 10 - 3 rem. A severe accident involv-<br />

ing severe impact and fire with an estimated frequency <strong>of</strong> once every 100,000 years would<br />

result in a maximum-exposed individual 70-yr whole body dose <strong>of</strong> 3 rem.<br />

4.8.2.4 Non-Radiological Impacts <strong>of</strong> Accidents in the Reprocessing Cycle<br />

Estimates <strong>of</strong> deaths and disabling injuries resulting from construction and decommis-<br />

sioning <strong>of</strong> reprocessing fuel cycle waste management facilities are given in Table 4.8.1.<br />

Injuries and deaths also result from transportation <strong>of</strong> the wastes. As in spent fuel trans-<br />

port, we use estimates <strong>of</strong> 0.36 disabling injuries and 0.039 deaths per million km for rail<br />

transport and 0.44 disabling injuries and 0.045 deaths per million km for truck transport.<br />

These injuries and deaths may occur either to the transportation worker or to the public.<br />

4.8.3 Radiological Impact Summary for Predisposal Operations Accidents<br />

Table 4.8.2 summarizes the radiation effects <strong>of</strong> the predisposal-system accident<br />

analysed for this Statement.<br />

This comparison shows that transportation is the waste management step with the<br />

potential for the most serious accident in either fuel cycle. The estimated exposures in<br />

these accidents, however, are not large enough to cause observable clinical effects. The<br />

individuals exposed would presumably bear an increased probability <strong>of</strong> developing cancer<br />

sometime during their life or <strong>of</strong> passing on a genetic defect.
