Description:

The Nuclear Instrumentation System Training Course will prepare the successful student to maintain the Nuclear Instrumentation System in accordance with plant procedures and vendor technical manual using all appropriate Human Performance tools.  This course is intended for I&C technicians and system engineers.  No previous experience with the Nuclear Instrumentation System is necessary, although some background in electronics may be helpful. 

Consistent with the Nuclearning® Educational Model, the Nuclear Instrumentation System Initial Training Course incorporates numerous student-centered learning activities to help the student learn and remember the concepts being studied. This approach puts the student at the center of the learning process making him an active participant in all learning activities. Specifically, the course incorporates instructor facilitated discussions, classroom exercises, equipment demonstrations, group work exercises, signal tracing, and hands-on troubleshooting.  Many actual plant problems are used to provide experience in troubleshooting common system failures.

It is very difficult, in operating plants, to find opportunities to train on actual plant equipment. The Nuclear Instrumentation System Training Course addresses this problem by using hands-on training equipment that is very similar to that found in the actual plant. This equipment provides the student with an invaluable opportunity to work on energized equipment in a safe, learning-friendly environment. In this environment, students can see the effect of switch manipulations, practice procedures, and troubleshoot problems while utilizing all of their human performance skills. The net result is the creation of a learning environment that is as similar to the plant as possible.

The Nuclear Instrumentation System Training Course is five (5) days (40 hours) in length. Since hands-on learning is an integral part of the course, the maximum number of students should be held to ten (10) or fewer.


Course Schedule:

The following is a high level, typical daily outline of the Nuclear Instrumentation System Training Course.  This daily schedule may vary due to student backgrounds and class pace.

Day 1

  • Integrated overview – The purpose of the Nuclear Instrumentation System in the nuclear power plant
  • Functional description

Day 2

  • Bistable operation
  • Isolation amplifier
  • Source range: block diagram, preamplifier, pulse amplifier, log pulse integrator

Day 3

  • Source range: signal outputs
  • Intermediate range: block diagram, log amplifier, power supply, testing
  • Power range: block diagram, signal processing, calibration

Day 4

  • Power range: rate circuit
  • FDMIC
  • Channel comparator
  • Startup rate: audio count rate, Source range functional test
  • Troubleshooting
  • Performance evaluations

Day 5

  • Source, Intermediate and Power range functional tests
  • Troubleshooting
  • Performance evaluations
  • Written exam review
  • Written exam* - A written examination will be used to test each student’s understanding of the system. The examination questions are based on the learning objectives used in the course.
  • Performance Evaluation** - Performance evaluations will also be conducted to assess the students’ capability to perform hands-on testing and troubleshooting.

*Westinghouse will provide one remediation exam (if required) for re-test of remediated student(s) in the event of a written exam failure. It is the responsibility of the utility to perform remediation activities and administer the remediation exam.  The utility must provide passing remedial exam scores to Westinghouse for documentation of satisfactory completion.

**If the course schedule allows, Westinghouse will provide one remedial performance evaluation (if required) for re-test of student(s) who fail their first attempt at performance evaluation.  If schedule limitations do not allow time for remedial performance evaluations to be given, remedial performance evaluations must be negotiated and scheduled in an offer separate from this course.

If applicable, this Nuclear Instrumentation System Course will cover any new-style circuit boards that the plant has installed. These boards will be covered first at the block diagram level and then at the schematic level. Emphasis will be on new test points and card edge indication. Since these boards are typically phased in over time, both the new and old style boards will be covered in the course.

Although Westinghouse does not grant a Nuclear Instrumentation System qualification to utility personnel for this training, many utilities, at their discretion, use successful completion of this course to grant a qualification.

The Westinghouse Nuclear Instrumentation System Training Course provides each student with a challenging and effective way to develop his or her understanding of this critical plant system.  By the end of the course, the successful student will have the knowledge and skills required to safely maintain and troubleshoot the Nuclear Instrumentation System.

Satisfactory completion of the course will be measured by achieving 80% or greater on a written exam and satisfactory completion of a performance evaluation.
