The ICCM-86 system training course satisfies the need for technician competency on Class1E equipment that alerts operators to conditions of inadequate core cooling during accidents.  Use of advanced 16-bit microprocessor technology in this system requires training in the latest state-of-the-art electronics using Intel 8086-based single board computers and peripherals.  Hands-on operation and maintenance of system hydraulic components and Intel-based circuit boards are provided in a laboratory setting, allowing the student to identify normal component operating parameters as an aid to troubleshooting the system.  System displays, local indications and maintenance terminal interfaces are discussed to provide the understanding necessary to efficiently isolate system faults in the hydraulics or electronics portions of the system.  Periodic maintenance items are discussed and will be performed on the actual field equipment.
