| The Refueling machine is one of the important equipment in a nuclear power station,takes on the task of the fuel loading and unloading,its performance can affec t the overhaul efficiency directly.This paper mainly takes the refueling machine of tianwan nuclear power station as the research object,analyses different overhaul refueling modes and optimizes the technological process of the refueling machine loading and unloading,in order to improve the operation speed and the more reasonable transportation process;At the same time,calculate the optimization effect and the time saved by each step of opt imization.The optimization integrated into each Technological cycle form a variety of logic algorithms,take into account the original blocking protection,add new blocking protection as needed,On the basis of safety and reliability,Achieve the optimal. |
