The Instrumentation and Control (I&C) System of the TRIGA reactor of the University of Pavia was dated (see Fig.1) and, in order to grant a safe and continuous reactor operation for the future, it became necessary to substitute or to upgrade the system. Since the substitution of the I&C system with a new-made one was very difficult to be performed due to long authorization procedures, an home-made refurbishment was planned. Using commercial components of high quality, almost a complete substitution, channel-by-channel, of the I&C system was realized without changing the operating and safety logics. The refurbished I&C system shows a very good operational behavior and reliability and will assure a continuous operation of the reactor for the future.

Abstract
The Instrumentation and Control (I&C) System of the TRIGA reactor of the University of Pavia was dated (see Fig.1) and, in order to grant a safe and continuous reactor operation for the future, it became necessary to substitute or to upgrade the system. Since the substitution of the I&C system with a new-made one was very difficult to be performed due to long authorization procedures, an home-made refurbishment was planned. Using commercial components of high quality, almost a complete substitution, channel-by-channel, of the I&C system was realized without changing the operating and safety logics. The refurbished I&C system shows a very good operational behavior and reliability and will assure a continuous operation of the reactor for the future.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
