Nuclear Fuel Complex, after assessing the need to increase production of nuclear fuel and zircaloy structural components to meet the requirement of the Indian Nuclear Power Programme, decided, in 2001 to enhance zirconium sponge production by setting up a project, Zirconium Complex (ZC) on a green-field site at Pazhayakayal in the port city Tuticorin in Tamil Nadu.

Zirconium Complex was commissioned in November 2009 to produce Zirconium Oxide and Zirconium Sponge to meet the enhanced demand.

The plant has been operating continuously and producing zirconium sponge at its rated capacity.

Use of zirconium and its alloys for nuclear applications requires stringent monitoring of quality of raw materials, chemicals and intermediate process streams / products. A Materials Testing Laboratory is set up for analysis of samples using state-of the art analytical instruments for process control and quality control of products.

Zirconium Complex was certified for Quality Management System as per ISO-9001:2015 by Bureau of Indian Standards (BIS) in 2018. Zirconium Complex was given an award for best quality assurance practices by Bureau of Indian Standards in October 2023.

Continuous efforts are madetowards improvement / development of production processes for higher production, better recovery, less consumption of chemicals and reduction of effluents. With these efforts, ZC is scaling new heights and excelling in fulfilling the mandates of the Department of Atomic Energy.

Atomic Energy Central School was established at ZC Township in March 2017 for providing quality education for wards of DAE staff and CISF Personnel.

Zirconium Complex has also established a Sea water Reverse Osmosis (SWRO) Plant for producing potable water from sea water.

ZC has following plans for:

  • Setting up of Magnesium Recycling Technology Development & Demonstration Facility.
  • Capacity augmentation of zirconium sponge production to meet the future demand commensurate with the nuclear power programme.
  • Augmentation of Zirconium Complex Township infrastructure to cater to the requirement.

For the welfare of the employees ZC has township and other amenities such as medical centre, shopping complex etc. for employees of ZC and CISF personnel.
