DOSE CALCULATIONS<br />

The time required to calculate doses for 104 years after production <strong>of</strong> the draft was<br />

not available. It is suggested that interpolations between results at 1000 and 100,000 may<br />

be sufficient for present purposes.<br />

Draft p. N.4<br />

Issue<br />

Repeated reference to discussion <strong>of</strong> trucker's dose on p. N.4 is misleading. The refer-<br />

ence on p. 13 indicates the discussion on p. N.4 explains the overestimate <strong>of</strong> the dose and<br />

the reference on p. N.16 indicates the discussion on p. N.4 is based on experience. The<br />

actual discussion on p. N.4 satisfies neither <strong>of</strong> these descriptions. (208-NRC)<br />

Response<br />

All <strong>of</strong> the truck drivers' doses in DOE/ET-0029 and the Statement are based on the con-<br />

servative WASH-1238 (AEC 1972) overestimate. The discussion on draft p. N.4 is an attempt<br />

to point out that the model results in an over estimate and actual values are smaller.<br />

The following quote from WASH-1238 (AEC 1972) is the basis for this statement.<br />

"Experience in truck transport <strong>of</strong> radioactive materials has shown actual doses to<br />

drivers to be 0.1 <strong>of</strong> the regulatory limit. Use <strong>of</strong> the regulatory limit <strong>of</strong> 2 rem/hour in any<br />

normally occupied space is therefore considered conservative."<br />

Draft p. N.4<br />

Issue<br />

Did this result take into account the growth <strong>of</strong> population along the transport route<br />

during the 70-yr period? (208-NRC)<br />

Response<br />

No, it did not.<br />

Draft p. N.4<br />

Issue<br />

An inconsistency exists between these two paragraphs. In the third paragraph, the<br />

draft states that population doses are calculated based on the permissible limit <strong>of</strong> radia-<br />

tion. Individual doses given in the fourth paragraph are taken from WASH-1238 which used<br />

dose rate values derived from experience rather than permissible limits. In addition, these<br />

WASH-1238 numbers were obtained from considering average exposures resulting from the trans-<br />

port <strong>of</strong> fuel and waste from power reactor. Since the discussion on page N.4 <strong>of</strong> the GEIS
