DRAFT
two areas of tunnel water effluent were visited and proclens in
connaction with the effluent were discussed.
Thare are 2 areas of Successive uvertiow ponds, about 30-54
feet in diameter, 15-¢25 feet deep, in a dowi-nill orientation
such that overflow as necessary is accomplished.
&y the time
water gets to the lower pond most of the water has evaporated.
The water contains tritium and other radionuclides.
A summary
of the content of the ponds will be attached to Mr. Vallario's
report.
Suffice it to say that the problem lies in tne fact
that flash floods in the area may wash some of tne containinated
water toward Yucca riats.
Its final place of denesiticn after
such) an overflow is not known.
A request for cost prediction
to pipe the outflow to an area down-hill for better containment
has been made.
The newly constructc! Secon Area (building) was briefly
visited.
Some Chefigas ars being made but tie butidtiec +6 used
as required (decaontaninacion for tainas uo to very haavy
equipment).
m
The
7”
cenfarence and fiei’ visit were enlightening anc very
worthwhile.
