In　order　to　give　lectures　on　nuclear　engineering　and　nuclear　technology　without　time　and　space　restriction,　this　paper　developed　a　network-based　real-time　PWR　nuclear　power　plant　simulation　software　(NUSOLSIM)　using　C/S　model.　The　software　modeling　the　system　equipment　of　the　core,　primary　circuit　and　secondary　circuit　of　PWR　nuclear　power　plant,　has　the　capability　to　simulate　typical　nuclear　power　plant　accidents　in　real　time,　with　pause,　save　and　graphic　output　buttons　on　the　user　interface.　Finally,　this　paper　uses　NUSOLSIM　software　to　analyze　two　DBC-2　events.　The　results　show　that　the　software　has　good　performance　in　accident　process　analysis.　©　2020,　Editorial　Board　of　Journal　of　Nuclear　Power　Engineering.　All　right　reserved.
