WASTE MANAGEMENT OPERATIONS<br />

The total amount <strong>of</strong> radiation in curies for each disposal site and for all sites and<br />

for each waste type should be stated. Also what percent <strong>of</strong> the radiation will still be<br />

left after 500 years? (62)<br />

Response<br />

The total curies <strong>of</strong> radioactivity disposed <strong>of</strong> in each <strong>of</strong> the five growth scenarios in<br />

the final Statement is identified in Tables 7.3.13 and 14. The number <strong>of</strong> repositories and<br />

thus the portion <strong>of</strong> the total radioactivity that may be disposed <strong>of</strong> in any single repository<br />

will depend on the specific site and the geologic media selected. The range <strong>of</strong> nominal<br />

2000 acre repository requirements for each <strong>of</strong> the nuclear growth cases is shown on<br />

Table 7.3.10. Figure 1.1 in the summary shows that the amount <strong>of</strong> radioactivity remaining<br />

after 500 years will be reduced by a factor <strong>of</strong> 100 to 500 or more relative to the amount<br />

originally placed in the repository.<br />

Response<br />

One commenter requested that more detail be provided on area thermal loading limits.<br />

Such information can be found in final Section 5.3, Appendix K <strong>of</strong> Volume 2, and<br />

Section 7.3 <strong>of</strong> DOE/ET-0028.<br />

Table 1.2 should present the repository acreage requirements for a 6,300 GWe-yr<br />

economy. (208-NRC)<br />

Response<br />

The relationship described on page 2.1.27 <strong>of</strong> the draft Statement shows that acreage<br />

requirements for the 6,300 GWe-yr growth scenario would be 63% <strong>of</strong> the requirements shown in<br />

Table 1.2.
