S o l u t i o n Temperatures The s o l u t i o n temperatures showed moderate temperature increases (138" F- 144' F ) when t h e ALCs were shutdown. s o l u t i o n , t h e temperatures are f a i r l y cons i s ten t . The changes t h a t d id occur a re due t o t h e l a c k o f s imple heat t r a n s f e r t h e ALCs prov ided when t h e cool ALC a i r i s bubbled through t h e warmer s o l u t i o n .
Tank Pressures
The tank never experienced an over p r e s s u r i z a t i o n throughout t h e t e s t i n g pe r iod . Pressures remained steady between -1.0 and -2.0 inches W.G. Th i s i s , o f course, because t h e temperatures never approached b o i l i n g anywhere i n t h e tank. Any f l u c t u a t i o n i n t h e vacuums are due t o changes i n the general p l a n t s t a t u s (i. e. i n l e t a i r f low, sw i t ch ing exhaust fans). The absence o f a "steam bump" i s f u r t h e r supported by the consistency o f t h e ca tch tank l e v e l . A steam bump would have generated a g r e a t deal o f steam which would have shown no t i ceab le r i s e s i n t h e ca tch tank l i q u i d l e v e l s .

Suspended Sol ids
An attempt was made to determine settling behavior by monitoring changes in suspended solids concentration at various levels in the tank. A probe was lowered down drywells 13-01-68 and 13-01-76 at six different times during the test. The probe was slowly raised while counts were taken and collected on a multi-channel analyzer, then plotted. Two techniques were used:
The first technique used is called Total G a m a Above Cesium (TGAC). involves measurements with a cadmium telluride (CdTe) detector of the total gamma interactions that are more energetic than the gamma-ray emitted from Cs-137. A region of interest (above the Cs-137 photopeak) was collected and plotted to generate activity profiles.
It
The second technique was used as a check of the first and it involves measuring a gross neutron count. A boron trifluoride detector is used to detect neutrons in the waste. Since the TRU isotopes emit neutrons and the TRU isotopes are solid, a profile of the neutrons detected can be plotted versus height.
The activity profiles of both detectors are similar as can be seen in Figures 29 and 36. Both profiles show that the sludge level remained steady at 18-20 inches. Unfortunately, specific settling behavior of the solids could not be determined using either probe.
CONCLUSIONS
The process test to shut down the ALCs in 241-AZ-101 was successful in that the three objectives outlined in the Process Test Plan were met. Under current 241-AZ-101 conditions, the airlift circulators can be shut down without experiencing an large or rapid temperature increase or a tank bump. In fact the tank will not reach the boiling point, even with the annulus exhauster shutdown.
The gamma probes did not work as well as expected, therefore, specific settling data (total suspended solids and settling rates) was not obtained. General information regarding total suspended solids was obtained from the sludge level data which the gamma probe provided. sludge level in 241-AZ-101 during the test which implies the tank solids were already settled before the test. This means either the ALCs do not suspend the solids or there is not enough solids to suspend (i.e. only 18 inch sludge 1 eve1 ) .
