Primary effort concentrated on optimizing waste loading of the
four different surrogate waste forms. Type 1 LETF Salts
successfully solidified at a loading ratio of 2:1 waste to
polymer. Initial formulations for Type 2 (Basin #1, #2 Sludge)
and T;Ye 4(Basin Crystal Solids) proved inconclusive.
Successful solidification of Type 3 (Basins #3, #4 Sludge) at a
loading ratio of 2:1 waste to polymer was achieved.
-BeYow is a synopsis of the experiments to achieve polymer/Type 2
waste (Basin #1, #2 Sludge) solidification:
1. Reduced waste loading to 0.5:1 waste to polymer ratio.
2. Increased the amount of promotor to forty times the required
amount.
... 3. Increased the amount of catalyst to twice the required
amount, along with an increase in promotor (20 times).
4. Changing the sequence of addition ( the standard way would be -
polymer and promotor mixed together first, add waste and mix, ".^
sd3--the-catall;st- and -firrish -mixing) - th®-promstcsr- and polymer
were mixedfirst then catalyst was added and "mixed in" the
waste.
5. Attempted mixing Type 1 and Type 2 waste together ( equal
weight ratios 1:1).
6. Experimented with ammonia water as a corrective additive to
induce this type of waste to solidify.
These experiments produced unacceptable results. The samples
gelled but did not get "rock hard".
All leach containers and bottles were acid rinsed in preparation
for the leachability and immersion testing. The core samples
were prepared. Fifty liter carboys of demineralized water and
synthetic sea water were prepared.

Mr. Dewey Burbank, Westinghouse Hanford, and Mr. Richard Henkle,
United Engineers & Constructors, visited Stock to observe the
preparation of samples to be tested. In the morning they
witnessed the making of the polymer control; Type 1 LETF Salts
