Abstract
A sodium-cooled nuclear reactor includes at least one electromagnetic pump assembly and a backflow reduction pipe. The backflow reduction pipe may include an inlet, an outlet, at least one tubular section having a first length and a first diameter, and at least one fluid diode section between the inlet and the outlet.
Claims13
A sodium-cooled nuclear reactor comprising:
- at least one electromagnetic pump assembly, the electromagnetic pump assembly including, a backflow reduction pipe including,
- an inlet,
- an outlet,
- at least one tubular section having a first length and a first diameter, the at least one tubular section between the inlet and the outlet;
- and
- at least one fluid diode section between the inlet and the outlet and configured to restrict backflow, the at least one fluid diode section including,
- a first section having a second diameter at a largest point of the first section, and
- a second section having a third diameter at a largest point of the second section,
- the first section closer to the inlet than the second section, the first section having a first radius at a widest point thereof, the second section having a second radius at a widest point thereof, the first radius being about 1.9 to about 2.2 times the second radius of the second section, and the first section and the second section being generally frustoconical in cross-section.
