ALTERNATIVE DISPOSAL CONCEPTS<br />

While it is not well enough advanced to be considered for an initial repository, this<br />

concept appears to have enough promise that it should receive some R&D funding. (154)<br />

Response<br />

Although DOE would like to restrict ourselves to only the most stable, uniform, and<br />

predictable areas, adequate areas can probably be found wherever natural uplifting and<br />

reprocessing processes have not occurred. One must be very careful to delineate overall<br />

global processes and to show where and why the highest reliability can be found.<br />

The subeabed program is currently being funded by the DOE. Fiscal year 1980 funding<br />

was for $5.9 million.<br />

Draft Section 3.6<br />

Issue<br />

The option has been under active development since 1973, and is considered one <strong>of</strong> the<br />

leading alternatives to the conventional geologic option. The development effort now<br />

includes four other countries, which recognize that an international approach may be neces-<br />

sary to an effective solution. (124)<br />

Response<br />

Six countries are now included in an NEA/OECD working group on subseabed disposal <strong>of</strong><br />

radioactive waste: U.S., Netherlands, Japan, Great Britain, France, and Canada.<br />

Draft Section 3.6.2.3<br />

Issue<br />

This section starts <strong>of</strong>f with the identification <strong>of</strong> the barriers to the movement <strong>of</strong><br />

radionuclides, then fails to discuss two <strong>of</strong> them: "any controlled modification <strong>of</strong> the<br />

medium," and "the benthic boundary layer." A discussion <strong>of</strong> these barriers should be pro-<br />

vided. (208-NRC)<br />

Response<br />

The various barriers are described briefly in the Section 6.1.4.2 <strong>of</strong> the final State-<br />

ment under <strong>Waste</strong> System Description.
