  1. 1. Effective Models for Simulation of Thermal Stratification and Mixing Induced by Steam Injection into a Large Pool of Water

    Författare :Hua Li; Pavel Kudinov; Michele Andreani; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermal Stratification; Mixing; Pressure Suppression Pool; Containment; Thermal Hydraulic; GOTHIC; Light Water Reactor; Fysik; Physics;

    Sammanfattning : Steam venting and condensation in a large pool of water creates both a source of heat and a source of momentum. Complex interplay between these two sources leads to either thermal stratification or mixing. LÄS MER

    Sammanfattning : The Pressure Suppression Pool (PSP) of a Boiling Water Reactor (BWR) is a large heat sink designed to limit the containment pressure by condensing steam released from the primary coolant system. The development of thermal stratification is a safety concern since it leads to higher containment pressures than in completely mixed conditions, and can affect the performance of systems such as the emergency core cooling and containment spray, which the use PSP as a source of water.
