RISYS: An Advanced Reactor Vessel Inspection System with .

Since the reactor vessel is cylindrical and the nozzle is conical, the intersection line is made by a cylinder and a cone in a 3 dimensional space. It can therefore be modeled as: X 2 +Y 2 = R 2 Y 2 +(Z-Z n) 2 = -k(X-X n) 2. where R is the radius of the reactor vessel in the shape of the cylinder, and k is the cone angle of the nozzle.

Control rod - Energy Education

Control rod - Energy Education

A control rod is a device that is used to absorb neutrons so that the nuclear chain reaction taking place within the reactor core can be slowed down or stopped completely by inserting the rods further, or accelerated by removing them slightly. Essentially, control rods provide real-time control of the fission process, ensuring that it remains active while preventing it from accelerating out of .
