Nuclear Power Corporation of India awards filtration leader supplier accreditation

28 Aug 2018

Porvair Filtration Group has achieved status as an accredited supplier to the Nuclear Power Corporation of India Limited (NPCIL), after qualifying and supplying its polymeric filter cartridges.

Initially being recognised as a supplier in 2013 to the Tarapur Atomic Power Station, Porvair was again invited to bid for a similar project at the Kakrapar Atomic Power Station (KAPP) and the Rajasthan Atomic Power Plant (RAPP) in 2017.

Porvair’s Microfil™ polymeric filter cartridges were selected for the filtration of cooling water in the plant’s moderator line. The installation of the filter was critical to prevent the build-up of radioactive particles in the system and consequentially the development of areas of high radioactivity, also known as hotspots.

As part of the qualification process, Porvair’s Microfil™ filter cartridges were tested in the presence of an independent witness from a leading regulatory body, in accordance with the NPCIL criteria to meet their Quality Assurance Plan.

This product testing confirmed the filter’s efficiency and compatibility with the process conditions encountered. The results demonstrated a significant safety margin that was above the recommended operating parameters of the process specifications.

In addition, tests confirmed the filter’s ability to resist the aggressive process conditions, including: high pH, high temperatures and deformation under pressure. What’s more, installation in heavy water applications has resulted in no reported degradation of the filter media due to radiation.
