RESOURCE REQUIREMENTS<br />

No basis for any <strong>of</strong> the values <strong>of</strong> resources committed shown in Tables 3.1.55, 62, 65,<br />

and 78 are given. In addition, no units are given for operational water use, concrete,<br />

propane and electricity in draft Table 3.1.55. (208-NRC)<br />

Response<br />

See DOE/ET-0029 for basis <strong>of</strong> values in draft Tables 3.1.55, 62, 65 and 78. Units for<br />

operational use <strong>of</strong> water (m3), concrete (MT), propane (m 3 ) and electricity (kW) were missing<br />

from draft Table 3.1.55. These omissions have been corrected.<br />

A question was raised as to how much energy would be required for the surveillance <strong>of</strong><br />

nuclear wastes following disposal. (30)<br />

Response<br />

DOE anticipates some type <strong>of</strong> post-closure monitoring system will be implemented for as<br />

long as future generations care to operate it. While the amount <strong>of</strong> energy expended would<br />

be dependent on the length and extent <strong>of</strong> the monitoring effort, it is anticipated that the<br />

energy requirements would be less than that needed for the operation <strong>of</strong> the various waste<br />

management facilities (equivalent <strong>of</strong> 0.08% <strong>of</strong> energy produced in power plants through the<br />

year 2050--250 GWe growth and decline scenario).<br />

Issue<br />

The third paragraph suggests that water use will not be a problem. The basis for the<br />

statement was the assumption that the facilities could all be located near the "R" River,<br />

which had adequate flow. However, the statement should recognize that water use could be a<br />

significant environmental impact for a repository which cannot be located near a convenient<br />

water source.<br />

The resource commitments listed include annual water use for the once-through fuel<br />

cycle option. The total annual use is about 1% <strong>of</strong> the annual mean flow <strong>of</strong> the "R" River, a<br />

small amount when water is plentiful. However, in the semi-arid west where river flows can<br />

be less than 100 cfs (one-fiftieth that <strong>of</strong> the R River) and where water is fully allocated,<br />

this is a significant amount <strong>of</strong> surface water use. (208-NRC)
