INCORE INSTRUMENTATION SYSTEM. I&C Training Programs

This course focuses on those components that, if not properly maintained, can result in unacceptable radiation doses and drive systems that are not fully operational. These include the drive motor assemblies, the path transfer devices and the sealing table. Also available for the practical training of students are the control panels normally located in the control room.

The course will explain the purpose and operation of moving core detectors and core output thermocouples. (At most plants, reactor engineering personnel operate this equipment and I&C personnel repair the system.)

Los ejercicios de rastreo de señales llevan a los estudiantes a través de los diversos modos de operación y explican dónde pueden ocurrir problemas. El mantenimiento mecánico se realiza en los componentes del motor de accionamiento, como el embrague y los codificadores de posición, y se analizan los procedimientos para reemplazar componentes como el detector y los sellos.
