Reactor power measurement by gamma and neutron radiation in Heavy Water Zero Power Reactor (HWZPR)

► A new approach for reactor power measurement is proposed. ► The proposed technique has been applied for gamma and neutron radiation from HWZPR reactor. ► NE213 detector has been used for reactor power measurement. ► The proposed technique has increased the redundancy and diversity for reactor power measurement. ► This proposed technique is on-line, prompt, and independent of safety and control rods and fuel configuration.
