  • Power for artificial arms from normal walking
    It is also found to be easy to operate the pumps by transferring weight from one foot to the other while standing still. The fluid pressure force at 500 lb/in2 (3.42 MN/m 2) is 55 lb t (245 N …
  • Improved Procedures for Injecting Radioisotopes During Fracturing Operations
    The injection pump transfers the radioisotope fluid to the suction of the downhole pumps through a discharge hose ranging from a few feet to more than lLKIft [30.48 m] in length. The radioisotope fluid is injected into the main slurry flow as near the downhole pump suction as possible. fnjectionof the radioisotope should k pfonned with only one of the downbole pumps if more than one is oper- ating , thus minimizing the contamination …
  • Assessment of alternative mitigation concepts for Hanford flammable gas tanks
    These pipes discharge approximately 3 112 feet from the tank bottom. When the desired amount of dilution fluid has been added to the tank, the existing mitigation pump will be operated to mix the waste and diluent. 5.3.2 Dilution to Meet Transfer Line Requirements .
  • Savannah River Site Interim Waste Management Program Plan FY 1991--1992
    From the purnp pit, the hot concentrate is continuously circulated by the main purnp through double-walled pipes, through the upper interior of several waste tanks in series, and back into the concentrate transfer system pump tank. Air- operated drawoff valves, esp.ecially designed to minimize stagltant holdup :+pace, are operated interrnittently under automatxc … This recirculation system is used to accommodate relatively low net drawoff rates (original design, 3 gpm) and still maintain, in practical-size piping (1-1/2 to 2 inches), sufficient fluid velc_:ity (>2 feet /second) to keep the fluid hot and prevent …
  • Savannah River Site Waste Management Program Plan, FY 1993. Revision 1
    From the pump pit, the hot concentrate is continuously circulated by the main pump through double-walled pipes, through the upper interior of several waste tanks in series, and back into the concentrate transfer system pump tank. Air- operated drawoff valves, especially designed to minimize stagnant holdup space, are operated intermittently under automatic control … This recirculation system is used to accommodate relatively low net drawoff rates (original design, 3 gpm) and still maintain, in practical-size piping (1-1/2 to 2 inches), sufficient fluid velocity (>2 feet /second) to keep the fluid hot and prevent settling …
  • BLENDING STUDY FOR SRR SALT DISPOSITION INTEGRATION: TANK 50H SCALE-MODELING AND COMPUTER-MODELING FOR BLENDING PUMP DESIGN, PHASE 2
    To develop the necessary technical basis for the design and operation of blending equipment, Savannah River National Laboratory (SRNL) completed scaled blending and transfer pump tests and computational fluid dynamics (CFD) modeling. The test tank represents a 1/10.85 scaled version of an 85 foot diameter, Type IIIA, nuclear …
  • Evaluation of Failed Crane Chempumps Used During Salt Well Pumping
    The saltwell system operated satisfactorily during the pumping campaign with one exception. The saltwell did not operate well at the high transfer rates, exceeding 2 gpm. System operating parameters suggested that a large solid particle was being lifted into the foot valve and interfering with the fluid flow between the venturijet and nozzle.
