WPPSS NUCLEAR PROJECT 1 & 4-f DRAFT ENVIRONMENTAL QUESTIONS RADIOLOGICAL ASSESSMENT BRANCH I
l 1.
a)
Provide actual values for dose estimates to the general public from
...........2,..
. directsradiation (p. 5.3-6)..
Describe the model.(including-source.,
term) used to obtain these doses.
i b) Provide the estimated annual dose at various locations in the Unit
.2-construction: area.from on-site radiation-sources such as.the
.~su.
e o6 Auxiliary Building, the Reactor Building, stored radioactive wastes,
[
and from radioactive effluents (direct radiation from the gaseous radioactive effluent plume).
Provide estimated annual doses to
. j.<.
.., -construction workers due to radiation from these. sources from Unit i...._.
1, and the annual man-rem doses associated with. such-construction.
l Include models, assumptions, and input data, i
2.
Provide the basis for the dilution factor of 1/1300 in Tables 5.3-4 and 5.3-5.
A more reasonable value the dilution factor for complete mixing of the effluent from units 1 and 4 with the Columbia River would ber (8.9&8.9)/120,000 or 1/6700.
3.
The 18" pipe mentioned on p. 5.3-1 is described as a 24" line in other parts of the ER.
This discrepancy should be resolved.
t
?
4.
The population dose from transportation of radioactive materials (p.
k 5.3-6) is for a single unit only (i.e., the doses taken from reference 5 are'or a "per reactor" basis).
- 5.. Provide the basis for the dilution factor of 10% mentioned on p. 5.2-1 and in Tables 5.3-4 and 5.3-5.
6.
The emphasis of the radiological surveillance program summarized in Table 6.1.5-1 should be redirected, as follows:
a) Ambient radiation measurements should be made at three additional locations (one of which should be a control location).
b) Atmospheric radioiodine measurements should be conducted at 50%
or more of the air monitoring statione.
l c) Rainwater samples may be deleted.
4 d) The number of soil sampling sites needs to be increased substantially (i.e., from 5 to about 13 - the new number of TLD sites). The j
sample frequency may be decreased from quarterly to trienially.

e) Milk samples from the nearest (location of highest X/Q) cow should be added to the program.
The analytical detection capability for I-131 for all milk samples should be 0.5 pC1/1 25%. A control station (15-20 miles distant) should also be es:ablished for milk.
l f) The term " aquatic life" (item 9.a) should be further defined j
(does it include fish?).
