WASTE MANAGEMENT OPERATIONS<br />

One commenter requested an explanation <strong>of</strong> the method used to obtain the values in<br />

Table 1.2. (208-NRC)<br />

Response<br />

The basis for repository area requirements shown in Table 1.2 <strong>of</strong> the draft Statement<br />

can be found for the once-through cycle in Table 7.4.2 <strong>of</strong> DOE/ET-0028 and for the reproces-<br />

sing cases in Table 7.5.3 <strong>of</strong> DOE/ET-0028. The total number <strong>of</strong> containers classified by<br />

waste type for each <strong>of</strong> the nuclear growth cases and the range <strong>of</strong> 2,000 acre repository<br />

requirements, considering the four geologic media, can be found in the final Statement in<br />

Section 7.3.<br />

Draft p. 1.11 and Chapter 4.0<br />

Issue<br />

Several letters questioned the range <strong>of</strong> repository availability dates (1985-2000) used<br />

in the draft Statement. (154, 181, 208-NRC, 219)<br />

Response<br />

The final Statement examines (under the proposed action) repository availability from<br />

1990-2010 (see Chapter 7.0).<br />

Issue<br />

Several letters expressed concern with the retrievability process.<br />

Draft p. 1.14--The retrieval capability <strong>of</strong> 5-50 years mentioned may be inadequate<br />

especially if a very serious incident occurs. (62)<br />

Draft p. 3.1.105--The whole question <strong>of</strong> retrievability is bothersome. The statement<br />

says that "This would involve returning to the emplacement rooms, removing the spent fuel<br />

canister from its sleeved hole with the same transporter originally used for emplacement,<br />

transporting the canisters to the receiving stations where they are hoisted to the surface<br />

and providing some sort <strong>of</strong> interim storage for the canisters until another repository is<br />

ready to receive the spent fuel." This assumes that the failed fuel canister is not so<br />

damaged that it can still be handled with the same equipment used for handling one which is<br />

undamaged; that "some sort <strong>of</strong> interim storage" is available for failed fuel canisters; and,<br />

that another repository will eventually be ready. There is doubt that another repository<br />

would ever be ready should the first one not work out satisfactorily. (35)
