Description

Results of heat transfer analysis and service life time estimation are presented for submerged electromagnetic pump (EMP) on liquid lead for reactor BREST-OD-300. EMP is planned to use for liquid lead level regulation in the reactor during putting it into exploitation under partial or full EMP submerging in lead. Main EMP parameters: pressure head 1.0 MPa, nominal flow rate 2.0 m3/hr, lead temperature 390-420 °С. Required service life time under nominal conditions is 1000 hours. Cylindrical linear induction pump was chosen as a result of optimization. Heat transfer analysis was done with ANSYS. Maximum EMP winding temperature was found to be 471 °С. Life time estimation of EMP based on these results proved that required duration 1000 hours was provided. The design of the mock-ups was chosen for carrying out life tests and confirming the pump resource.
