which these impacts are based are alternatives to be considered in addition to the refer-<br />

ence case is not clear. If the latter is true, then the impact <strong>of</strong> building rail spurs to<br />

the 50% <strong>of</strong> reactors that do not have these spurs should be given in the GEIS. For the<br />

reference case, the impact <strong>of</strong> transporting the spent fuel by truck from these reactors to<br />

the nearest rail siding does not appear to have been included in the analysis. (208-NRC)<br />

Response<br />

The impact <strong>of</strong> 100% shipment by rail or truck are presented for comparison purposes only<br />

and are not alternatives to the reference case. For the reference case, the impact <strong>of</strong><br />

transporting the spent fuel by truck to the nearest rail siding has not been included in the<br />

analysis.<br />

Draft pp. N.3 and N.4<br />

Issue<br />

Impacts presented on p. N.3 (Tables N.3 and N.4) and on p. N.4 are based on the assump-<br />

tion that all spent fuel is shipped by either rail or truck. Values given in DOE/ET-0029<br />

are based on the reference case <strong>of</strong> 90% <strong>of</strong> the spent fuel being shipped by rail from reactors<br />

to ISFSFs and 10% by truck with 100% <strong>of</strong> the shipments from ISFSFs to the final repository<br />

being transported by rail. We recommend converting the results presented in Table N.3<br />

and N.4 and on page N.4 to the reference case so that actual resource commitments can be<br />

known and comparison <strong>of</strong> the GEIS with the backup documentation can be facilitated.<br />

(208-NRC)<br />

Response<br />

Since this reference case is already presented in DOE/ET-0029, the corresponding<br />

portion <strong>of</strong> Appendix N is not required and was therefore deleted. See DOE/ET-0029.<br />

Draft pp. N.3 and N.4<br />

Issue<br />

It is not clear that the impacts shown in the GEIS have been correctly obtained from<br />

DOE/ET-0029. The following discussion develops ratios which can be applied to the results<br />

in DOE/ET-0029 to convert them into results that would be obtained if 100% <strong>of</strong> all shipments<br />

are transported by either rail or truck. Following this ratio development discussion is a<br />

table outlining some cases where impacts presented in the GEIS appear to have been impro-<br />

perly obtained from DOE/ET-0029.<br />

Table 26.2.3 <strong>of</strong> DOE/ET-0028 shows 7,370 packaged PWR assemblies and 11,340 packaged BWR<br />

assemblies needed shipment from ISFSF to a final repository in the year 2000. In the refer-<br />

ence case these assemblies would be shipped by rail in a modified NLI 10/24 cask which can
