Draft Section 3.7<br />

Issue<br />

379<br />

ALTERNATIVE DISPOSAL CONCEPTS<br />

This concept would provide a high degree <strong>of</strong> isolation (our terminology - make man's<br />

intrusion unlikely). However, the litany <strong>of</strong> unresolved technical and political problems<br />

make it clear this concept cannot possibly be considered for an early repository. Further-<br />

more its cost would likely rule it out for even much later consideration. (154)<br />

If the 1% heat load criterion is reasonable (draft p. 3.7.8) then it should be stated<br />

and the high area (7%) demand would rule out the Antarctic approach. This report requires<br />

better perspective to be useful. A clear statement should be made to rule out this<br />

alternative. (124)<br />

The 10-30 years <strong>of</strong> extra lead time required for ice sheet disposal, as compared to<br />

other disposal options, will delay implementation <strong>of</strong> a publicly acceptable nuclear waste<br />

management system...(Section 3.7.5.4) should be highlighted, because it makes this option<br />

extremely unattractive to comparison to others whose technology is more developed. (124)<br />

Response<br />

Section 6.2 <strong>of</strong> the final Statement presents a comparison <strong>of</strong> the attributes <strong>of</strong> alter-<br />

native concepts and the mined repository. This comparison employs the use <strong>of</strong> standards for<br />

judgment to evaluate the concepts for the purpose <strong>of</strong> identifying preferred concepts. In<br />

general, concepts that have significant technical and environmental performance uncertain-<br />

ties are lower in preference than the better defined concepts. The ice sheet concept is,<br />

therefore, one <strong>of</strong> the lesser preferred concepts.<br />

Draft Section 3.7<br />

Issue<br />

The section treats rather severe transportation problems in a rather causal manner and<br />

without appraisal <strong>of</strong> non-radiological hazards. A more thorough and complete treatment <strong>of</strong><br />

transportation, including accident and non-radiological hazards, should be provided. (58)<br />

Under Section 3.7.1.5, the risks, hazards, and impacts <strong>of</strong> transporting HLW over ice in<br />

polar climates should be presented. (208-NRC)<br />

The quality <strong>of</strong> the reasoning contained in the DEIS might be called into question by<br />

the apparently serious consideration <strong>of</strong> rather bizarre and untested methods <strong>of</strong> transport<br />

and emplacement <strong>of</strong> the waste in the Antarctic ice-sheet. The horrendous logistics problems<br />

<strong>of</strong> the Antarctic repository are discussed at length with no apparent consideration <strong>of</strong> the<br />

need for recognition and quantification <strong>of</strong> non-radiological hazards. (58)
