Experimental Studies at AERB-SRI, Kalpakkam

AERB is also involved in experimental studies relevant to safety of nuclear and radiation facilities for
independent verification, development of correlations, validation of computer codes or models etc. The
following Experimental studies were performed.

• Cable fires studies in Compartment Fire Test Facility (CFTF).
• Studies on fires in electrical cabinets containing components critical to
reactor safety.
• Studies on passive hydrogen removal at HYdrogen MItigation Facility
(HYMIF).
• Condensation Induced Water Hammer (CIWH) experiments
in Water and Steam Interaction Facility (WASIF).
• Conducted experiments on AGMS and Coolant Channel Heat-up Facility.
• Conducted experiments in Core Melt Retention Facility.
