Chemical Pretreatment of Nuclear Waste for Disposal

Chemical pretreatment of nuclear wastes refers back to the series of separations tactics used to partition such wastes right into a small quantity of high-level waste for deep geologic disposal and a bigger quantity of low-level waste for disposal in a near-surface facility. Pretreatment of nuclear wastes now saved at numerous U.

Consequently, it is necessary to prepare samples for DTA in a manner that ensures analogous crystal forms at all conditions and to eliminate or account for recrystallization during the run. Furthermore, it is necessary to prepare stable suspensions to avoid the possibility that settling will change the concentration of the active species. E. 1% w solutions followed by filtration and resuspension of the crystals in fresh solvent. 75% w or greater did not settle noticeably. The thermograms for the suspensions are shown in Figure 1, and the data in Table I.

Salovey Bell Telephone Laboratories, Incorporated Murray Hill, New Jersey Chain folded polyethylene single crystals grown from dilute solutions at undercoolings of 2o-4ooc are metastable.

The effect can be seen in the thermograms of Figure 3. The crystals used to obtain Trace II were not filtered at the crystallization temperature and had a thinner border. The peak corresponding to the recrystallized polymer was in this case completely eliminated by isolation of the crystals at the crystallization temperature. Therefore, it is necessary to separate the crystals from the mother liquor at the crystallization temperature to inhibit recrystallization during DTA. It is desirable to extend observations to the highest possible temperatures.
