CONSEQUENCE ANALYSIS<br />

DOE/ET-0029 presents a more detailed discussion <strong>of</strong> the release scenarios analyzed in<br />

the Statement.<br />

Draft p. 3.1.70<br />

Issue<br />

Response<br />

The last sentence in paragraph 3 contradicts the first two. (218-DOI)<br />

The subject paragraph was deleted from the final Statement.<br />

Draft p. 3.1.71<br />

Issue<br />

It should be noted that all numerical models will require more satisfactory verifica-<br />

tion on a variety <strong>of</strong> real field problems before they can confidently be applied to very<br />

long-term and large scale prediction. (218-DOI)<br />

Response<br />

DOE agrees with the commenter and would point out that field verification <strong>of</strong> mathemat-<br />

ical models is an on-going effort and is an essential element in repository safety<br />

assessment.<br />

Draft p. 3.1.71<br />

Issue<br />

One commenter alluded to the Stone and Webster computer errors in determining piping<br />

loads during earthquakes and stated that the computer codes used in the Statement will even-<br />

tually be shown to be in error. (30)<br />

Response<br />

Modeling <strong>of</strong> complex systems is approximate at best. Codes are continually being<br />

checked and it is hoped that the comment will not prove true to a significant extent in this<br />

Statement.
