Abstract: Simplicity in defining the reactor operation through shaped normalised reactor period function, helps to define control laws for efficient reactor control. This function is invariant for any set-manoeuvring rate, consistent with reactor physics rules, and thus generates control laws close to physics. This paper deals with the derivation, properties and application of the normalised shaped reactor period function. This function is already applied for reactor control of PHWR 540 MW.
