Quarterly review of 241-SY-101 mixer pump data: October - December, 1998

PDF Version Also Available for Download.

Description

This report presents data obtained on 241-SY-101 pump performance. The period covered is October 1 through December 31, 1998. During the quarter: (1) There was an indication of a 7.0-inch increase in the waste level at riser lA, and an average growth rate of 0.076 inches per day. (2) There was an indication of a 2.3-inch increase in the waste level at riser 1C. This riser was flushed with water several times, which would lower the level of the crust at this location. (3) Gases continued to be released at less than the pre-pump installation baseline rate, indicating a decrease ... continued below

Description

This report presents data obtained on 241-SY-101 pump performance. The period covered is October 1 through December 31, 1998. During the quarter: (1) There was an indication of a 7.0-inch increase in the waste level at riser lA, and an average growth rate of 0.076 inches per day. (2) There was an indication of a 2.3-inch increase in the waste level at riser 1C. This riser was flushed with water several times, which would lower the level of the crust at this location. (3) Gases continued to be released at less than the pre-pump installation baseline rate, indicating a decrease in the gas generation rate, or an increase in gas retention, or both. The release rate was about 60 percent of the rate in the previous few quarters, and only 44 percent of the pre-pump release rate. (4) There was no change in the parameters that monitor pump performance. Key controls exist for waste temperature, gas concentration, pump parameters, and long-term waste behavior associated with the safe operation of the mixer pump that mitigates the buoyant displacement gas release event behavior of 241-SY-101. Table 1-1 compares the key controls and the current state of the waste as of December 31, 1998.
