wastes do become substantial for delayed repository availability. This is shown in<br />

Table 7.3.4. The range <strong>of</strong> storage requirements for high-level waste canisters is affected<br />

not only by repository availability but also by the heat limitation on canisters for the<br />

different geologic media. For example, only about 1/3 as much high-level waste can be<br />

placed in a single canister for a repository in shale as can be placed in a canister for a<br />

repository in salt (see Section 5.3)..<br />
