Magnetic cores design flow

Superior water conditioners. These are tubular-shaped devices that employ permanent magnets (no electrical connection). The devices are designed with a cobalt-content alloy core, arranged so that water flows around the magnetic core and perpendicular to the magnetic fields. 

N in the figure) and dt secondary coil (designated as N, ). Electric current through the primary coil causes a magnetic flux in the core and at the same time an impedance to the current and therefore an induced emf across the primary. The magnetic flux in the core in turn induces an emf across the secondary coil, causing a current to flow. The relation between the emf induced in the primary coil (note that this is not the source emf) and the emf induced in the secondary coil is given by... 

A new type of hydraulic drive mechanism is used to drive the control rods in HR-200. In the drive system the reactor coolant (water) is the actual medium. The water is pumped into step-cylinders of which the movable parts contain the neutron absorber. A pulsed flow, generated by a controlling magnetic valve in the control unit moves the movable part of the step-cylinder step by step. The drive system is very simple in its stmcture and is designed on the "fail-safe" principle, i.e. all control rods will drop into the reactor core by gravity under loss of electric power, depressurization, postulated breaks in its piping systems and pump shut down events.
