Reactor riser
WebA nuclear heating reactor (NHR) is a typical integral pressurized water reactor (iPWR) with advanced design features such as an integral primary circuit, self-pressurization, full-power-range natural circulation, and hydraulic control rods. Through adjusting its electric power output according to the variation of demand, NHR power plants can be adopted to … WebRepairs are time consuming, and can be difficult to effect, for example in catalyst transfer lines, reactor riser, or reactor overhead vapor line to the main fractionator. These refractory failures occur for various reasons, one of which is obviously age of the linings.
