CONSEQUENCE ANALYSIS<br />

Even on the basis <strong>of</strong> incredibly pessimistic assumptions the accident caused by solution<br />

mining in a salt repository is shown to have negligible consequences. In this case we find<br />

somewhat higher values than the draft EIS. Is it possible that the decontamination factor<br />

referred to on p. 3.1.171 was applied? (154)<br />

Response<br />

The decontamination factor was not used.<br />

Draft pp. 3.1.179-192<br />

The potential hazards <strong>of</strong> storage and transportation <strong>of</strong> radioactive waste did not<br />

include justification <strong>of</strong> the accident frequencies (the number <strong>of</strong> occurrences over a given<br />

time period) that were used. (40)<br />

Response<br />

Basis for the analysis <strong>of</strong> predisposal activities, including accident frequencies, are<br />

detailed in the support document DOE/ET-0028. DOE/ET-0054 (DOE 1978a) also contains an<br />

analysis <strong>of</strong> storage and transportation <strong>of</strong> spent fuel.<br />

Draft p. 3.1.200<br />

Issue<br />

Several commenters noted that more complete analysis should be performed on the poten-<br />

tial for accidents during storage and transportation <strong>of</strong> PuO 2.<br />

Statement is made that "no accidental release <strong>of</strong> radioactive material is postulated for<br />

shipments <strong>of</strong> plutonium oxide." DOE has achieved perfection. No accidents with plutonium<br />

oxide in transportation will occur. (30)<br />

There is a very brief discussion <strong>of</strong> a criticality accident in a storage facility for<br />

plutonium oxide. If anything, this treatment is even less convincing than the others. The<br />

suggestion is made that 200 grams <strong>of</strong> stored plutonium oxide would reach the atmosphere in<br />

the worst criticality accident. As you know, this is a very large amount, biologically<br />

speaking. But the progress <strong>of</strong> such an accident is never discussed. Rather it is claimed<br />

that the maximum 70-yr total body dose commitment to any individual would be 75 millirems.<br />

Similarly, these paragraphs imply that no accident analysis has been done for a surface<br />

storage facility for plutonium oxide. (40)
