5.4.6.1 Resource Commitments<br />

Resource commitments for operation <strong>of</strong> a geologic repository for spent fuel are sum-<br />

marized in Table 5.4.12. Resource commitments for operation <strong>of</strong> a geologic repository for<br />

fuel reprocessing wastes are summarized in Table 5.4.13.<br />

5.4.6.2 Nonradiological Effluents<br />

The major nonradiological effluent from facility operation would be fugitive dust emis-<br />

sions from surface handling <strong>of</strong> mined materials, as was discussed under construction impacts<br />

(Section 5.4.4). Other nonradiological pollutants released to the biosphere during the<br />

repository's operational life are given in Tables 5.4.14 and 5.4.15 for the various geologic<br />

media. These pollutants include combustion products from burning diesel fuel (URS 1977)<br />

during underground mining operations and from surface burning <strong>of</strong> coal (OWI 1978).<br />

The estimated releases <strong>of</strong> pollutants from a geologic repository as given in<br />

Table 5.4.14 would not, in any case, result in Federal Air Quality Standards being exceeded<br />

at the repository boundary. For example, the maximum concentration <strong>of</strong> particulates at the<br />

repository boundary (1.6 km from point.<strong>of</strong> release, where the 7/Q' is 1 x 10 - sec/m 3 ) was<br />

3 3<br />

estimated to be 0.8 Pg/m compared to the standard <strong>of</strong> 75 vg/m 3<br />

Heat released from buried nuclear waste will increase the temperature <strong>of</strong> the geologic<br />

formation in which it is buried and may alter the physical and chemical properties <strong>of</strong> the
