Encrypment of the contaminated material will be at the
Cactus Crater
site withne
the mound adjusted to accommodate the
volume of contaminated material generated by the cleanup operations.
Consideration has been given to the use of LaCrosse Crater in addition
to Cactus Crater but is not recommended since more time, materials and
tet
costs will be incurred under this scheme,

See Appendix A.
Recommended sequence of contaminated material placement is
as follows:
(1)
of crater.
Dump large pieces of radioactive material into bottom
Material should be well dispersed to preclude subsequent
material from "hang-up",
prevent voids.
Scrap metal should be cut up into pieces to
The dispersion should be monitored to assure optimum
placement of concrete slurry,
Place concrete slurry with concrete pump and barge as shown
on the drawings.
