ALTERNATIVE DISPOSAL CONCEPTS<br />

Such information is not currently available for HLW waste injection. Other informa-<br />

tion that is presented'in the final Statement should be adequate, however, to provide a<br />

comparison <strong>of</strong> the technical alternatives for the disposal <strong>of</strong> HLW, spent fuel, contact hand-<br />

led TRU, and remote handled TRU wastes.<br />

An example <strong>of</strong> the assessment <strong>of</strong> deviation <strong>of</strong> grout sheets from a horizontal is given<br />

in the Environmental Statement for the ORNL operation.<br />

Draft p. 1.29<br />

Issue<br />

The total capital cost for grout injection facilities at all five disposal sites is<br />

estimated to be $300 million with $10 million for annual operating costs. To which fuel<br />

cycle does this apply? Also what type <strong>of</strong> wastes do 12 states prohibit from being injected<br />

into deep wells? (147)<br />

Response<br />

Section 6.1.6.6 <strong>of</strong> the final Statement contains a more up to date and accurate discus-<br />

sion <strong>of</strong> cost. The type <strong>of</strong> waste that "12 states prohibit from being injected into deep<br />

wells" is high level waste.<br />

Draft Section 3.8<br />

Issue<br />

The report treats Shale Grout Injection as a form <strong>of</strong> Reverse Well Injection. The lat-<br />

ter should be treated separately, since the shale fracture aspect and the waste fixation in<br />

grout represent very different forms <strong>of</strong> isolation than that for reverse well injection <strong>of</strong><br />

liquid waste in porous formations. (11)<br />

Response<br />

In preparing the final Statement, the section on well injection (Section 6.1.6) was<br />

revised in order to more clearly delineate between the shale grout injection and the re-<br />

verse well injection techniques.<br />

Draft Section 3.8<br />

Issue<br />

In today's climate, and considering the exquisite detail with which the possibility <strong>of</strong><br />

leaching <strong>of</strong> highly insoluble waste forms might occur was discussed in Section 3.1, it is<br />

inconceivable that either "reverse well" concept could possibly be acceptable politically<br />

in any foreseeable future. (154)
