A review of selected portions of the ARHCO waste tank farm monitoring methods and systems was made. Only preliminary evaluations were made as the study was carried out over a period of only ten days. The study was requested by the Operation Support Engineering Department of ARHCO and the objectives as developed were divided into four tasks. Briefly, these were: evaluation of the waste tank dry well monitoring and data processing systems; evaluation of the accuracy (and precision) of material balance calculations for transfers from one tank to another tank; evaluation of the capabilities of material balance techniques for the …

Description
A review of selected portions of the ARHCO waste tank farm monitoring methods and systems was made. Only preliminary evaluations were made as the study was carried out over a period of only ten days. The study was requested by the Operation Support Engineering Department of ARHCO and the objectives as developed were divided into four tasks. Briefly, these were: evaluation of the waste tank dry well monitoring and data processing systems; evaluation of the accuracy (and precision) of material balance calculations for transfers from one tank to another tank; evaluation of the capabilities of material balance techniques for the detection of leaks in evaporator bottoms loop systems; and evaluation of the general operability of liquid level instrument systems currently in use and alternatives to these systems. The objectives of these tasks are restated in more detail in each of the sections below. An overview of the entire Hanford radioactive waste program including a limited description of the physical equipment involved can be found in PWM-530, Hanford Radioactive Waste Management Plans. Additional efforts have been initiated to establish an overall R and D program to more fully evaluate these systems and other factors relative to the successful operation of the ARHCO tank farm system.
