Shielding And Sealing Plugs By Avasarala Technologies Limited

By taking advantage of our large industrial experience in this sector, we are associated with Manufacturing and Distributing an array of Shielding And Sealing Plugs from Pondicherry, India. These are employed for encasing fuel elements inside coolant channels of the 220MWe reactor. Works on the principle of mechanical face locking between metal to metal. Functions include retention of fuel elements, creation of a barrier between heavy water and vault environment on either side of each of the coolant channel.
An exclusive in-house facility created to ensure conformance to stringent specifications. A dedicated machining and inspection line employed for non-contamination of carbon steels. Assembly and cold run tests using dedicated fixtures in clean environment

Criticalities:
Works in coolant channel directly facing active heavy water having 1000Rems/hour radiation levels at 175 Deg. C temperature.
Has mechanical feature to facilitate unmanned robotic handling by fuelling Machine Heads.
Performs uninterruptedly ensuring high reliability.
Withstands a test pressure of 90-110 kgf/cm2 in sealed condition.
Have assured interchange ability at component level and full assembly level.
Development of Thick Nickel Coating on Stainless Steel.
