Title: Heat Balance Study for Submersible Mixer Pump

Abstract

A transient heat balance model was developed to assess the impact of a Submersible Mixer Pump (SMP) on waste temperature during the process of waste mixing and removal for the Type-I SRS tanks. The model results will be mainly used to determine the SMP design impacts on the waste tank temperature during operations and to develop a specification for a new SMP design to replace existing long-shaft mixer pumps used during waste removal. The model will also be used to provide input to the operation planning. This planning will be used as input to pump run duration in order to maintain temperature requirements within the tank during SMP operation.

  • The purpose of this task is to characterize the physical properties of kaolin/sand slurry used to test the performance of a new submersible mixer pump which is undergoing performance testing at the TNT Waste Tank mockup facility. Three different sample locations, the SMP cooling water exit, the SMP fluid flow field, and SMP effective cleaning radius were used for sampling over the seven day test. The physical properties determinations for the kaolin/sand slurry samples include rheology, weight percent total solids (wt TS), density, and particle size distribution were requested, though not all these determinations were performed on all the samples.more » The physical properties determinations are described in more detail in section 1.0. Measurements were performed at Savannah River National Laboratory in accordance with the Technical Assistance Request (TAR)1. The data, average of two measurements, is shown in the table below. This data clearly shows that the SMP-CWE samples contained more so lids than those at other sample locations for a given sample day. The SMP-FFF and SMP-ECR were similar in solids content. The rheology of the samples is dependent on the wt solids concentration and are all within the bounds stated in the TAR.« less
  • The objective of this evaluation was to determine whether a single rotating pump located 20 ft off-center would adequately mix expected AN-101 waste. Three-dimensional, AN-101 pump jet mixing simulation results indicate that a single, 20-ft off-centered mixer pump would mobilize almost all solids even at the furthest tank wall for sludge yield strength up to 150 Pa or less. Because the yield strength of the AN-101 waste was estimated to be less than 150 Pa, the AN-101 pump mixing model results indicate that a single mixer pump would be suffice to mobilize bulk of the disturbed and diluted AN-101 solids.
  • The pump-to-motor mixing rate of the ByronJackson 4000-gpm pump was determined as a function of motor purge flow. A purge rate of 63 liters/hr, which corresponds to a mixing rate of 0.55 liters/hr, is recommended for operation of this pump. Further increases in purge flow did not decrease the mixing rate significantly below this level. Two runs were made with cooling water bypassing the external motor cooler. These runs indicated that the external cooler was necessary to prevent overheating of the 4000 gpm pump motor. However, the observed heat balance checked the predicted heat balance, indicating that the method ofmore » prediction can be applied to the design of motor« less
  • The hourly power demand and heating- and cooling-mode energy use of electric air source heat pumps in single-family residences was analyzed and correlated. Field data from 50 houses in five different geographical locations, representing a range of 1434 to 8310 heating degree days and 2889 to 527 cooling degree days, were selected from a previous field study. A subset of the data was used to test a residential building-heat pump simulation model. Calculated daily heating energy consumption agreed to within 10 to 27% of the measured values; daily cooling energy consumption agreed to within 12 to 23% of the measuredmore » values. A Monte Carlo simulation procedure was developed for the prediction of heat pump diversified demand of a probability sample of residential customers on the basis of certain customer-class, equipment, and weather-related characteristics. Due to lack of valid field data, only a crude test of this procedure was possible, but it indicated that this method holds promise in simulations where test metering data are unavailable.« less
