Nuclear reactor safety system

Boiling water reactors are able to SCRAM the reactor completely with the help of their control rods. [2] In the case of a loss of coolant accident (LOCA), the water-loss of the primary cooling system can be compensated with normal water pumped into the cooling circuit. On the other hand, the standby liquid control (SLC) system (SLCS) consists of a solution containing boric

Why Reactors are used in Power Systems and their Types

Reactive Power Compensation: Power systems consist of both active power (real power) and reactive power. Reactive power doesn''t perform useful work, but it''s necessary for maintaining voltage levels and ensuring the proper functioning of the power system. Reactors can be used to provide reactive power support by either absorbing (capacitive

What are the different types of reactors?

This article highlights two common types of reactors which are the dry-type and the oil-immersed. In an AC circuit, reactance is the opposition to current flow. A reactor, also known as a line reactor, is a coil wired in series between two points in a power system to minimize inrush current, voltage notching effects, and voltage spikes.
