Abstract: Ion chambers for reactor control and safety instrumentation have been indigenously developed. The chambers are used for on-line neutron flux measurement in reactor out-of-core location. The chambers have a rugged mechanical design with integral mineral insulated cable assembly capable of operating in hostile environment. The electrodes were coated with 350 mg of 92% enriched elemental boron-10 and the theoretically expected neutron sensitivity of 2.9 x 10-14 A/nv has been achieved. Tests on one of the chambers show good saturation at 1.o x 108 nv. If necessary, the chamber can be operated at neutron flux of the order of 1.0 x 1011 nv.
