Plant dynamics studies towards design of plant protection system for PFBR

Experimental studies on CSRDM specimen to validate the use of Ritz vectors for the response evaluation of structures subjected to multi-support excitation

“…The main function of control rods in a nuclear reactor is to control the neutronic power generated in the core and to trip the reactor in case of accident (Rajan Babu et al, 2010). Chyou et al (2004) and Natesan et al (2012) conducted a series of tests and design improvement to ensure the mechanical integrity and durability of a prototype control rod drive mechanism. Tachibana et al (2004) had described various tests to be performed on the control rod system to ensure safety of the reactor.…”

Simplified method for measuring the response time of scram release electromagnet in a nuclear reactor

“…The evolution of sodium flow and temperature in all parts of the plant during various design basis events are investigated and the maximum permissible delays in instrumentation responses have been worked out to ensure plant safety under all transient conditions (Natesan et al, 2012). to the electromagnet clutch release (called as 'EM response time' hereafter).…”
