The invention relates to a nuclear reactor cooling apparatus, and concretely relates to a welding joint titanium alloy zirconia nuclear reactor cooling assembly. A nuclear reactor interlayer body foot stool is positioned in the inner cavity of the bottom cover of a lower hemisphere, the lower hemisphere is placed on a reactor bottom tank bottom plane through supporting foot stools arranged on the external surface of the bottom cover of the lower hemisphere, a forced cooling cylinder body is fixed above the bottom cover of the lower hemisphere in a sealing manner through a clamp, the outside of the top of the top cover of an upper hemisphere is provided with a filler sealing hole, and the excircle of a control lead tube is fixed in the filler sealing hole on the top of the nuclear reactor interlayer body in a sealing manner; the sidewall in the cylinder of the forced cooling cylinder body is provided with a spiral flow deflector, and the inner edge of the spiral flow deflector is in clearance fit of the outer edge of the nuclear reactor interlayer body; and the bottom cover of the lower hemisphere is connected with a welding joint discharging hole on a welding joint exchanger through a high pressure pipeline, and the top cover of the upper hemisphere is connected with a welding joint back pressure hole on the welding joint exchanger through a back pressure pipeline.
Description
technical field [0001] The invention relates to a forced cooling device for removing decay heat from a nuclear reactor, and the international patent classification is G21C15 / 18, in particular to a welding head titanium alloy zirconia nuclear reactor cooling assembly. Background technique [0002] There are various structures of nuclear reactors used to generate electricity. In terms of coolant circulation, they can be roughly divided into reactors with forced coolant circulation and natural circulation. As we all know, the coolant of a forced circulation reactor, usually water, circulates through the core where the nuclear reaction occurs, takes away heat from the core, flows to the outside of the reactor vessel through the pipeline, and releases the heat to the dedicated In the heat exchanger, and then pumped back to the core. Known so-called "centralized" reactors have no external piping, and the heat exchangers are located in a vessel containing the core. However, this ...
