The new ICP system was tested and found to be working properly. Subtask 1.7 Guided wave nondestructive evaluation technique development and demonstration. Also, modifications on the graphite rods are being considered. Several materials related issues still remain due to the increase in the length of the buffer rod. On the guided wave technique for tank wall NDE, further work on modeling was conducted.
Some initial results are encouraging.
Subtask 3.1 Validation and application of the environmental simulation program. O were initiated. The results at 25C and at the other temperatures will be formally evaluated and then converted for use in an ESP data bank. The results remove a deficiency within the ESP software and allow more accurate predictions of the double salt in future simulations applied to the Hanford wastes. Subtask 3.6 Ceramic regenerative heat-storage device for dioxin control and heat storage.
