| The Westinghouse 7300 Process Control System Continuing Training class focuses on solving actual hands-on troubleshooting scenarios using the Westinghouse 7300 Training System and training system schematics. Because of the aggressive course pace and the availability of only one 7300 Training System, the maximum class size is limited to eight students. Any optional requirements for formal troubleshooting performance evaluations may limit class size even further. The classroom phase of continuing training is structured toward recognition of normal and abnormal signal conditions within the 7300 Process Control System, and relies heavily on the students’ previous 7300 knowledge. Identification of normal and abnormal signals allows the student to develop corrective actions to quickly restore normal system operation. When feasible, the Six-Step Troubleshooting Process is combined with plant-specific practices. The continuing training course consists of classroom lecture, discussions, equipment demonstrations, test point signal recognition, and "hands-on" troubleshooting techniques. The students also review recent industry practices and events, where applicable. Westinghouse uses many typical trouble scenarios to provide experience in troubleshooting system failures. Where appropriate, the students use plant specific schematics and/or procedures for 7300 troubleshooting. |

The 7300 Process Control System Continuing Training Course opens with a presentation of the course objectives, and an overview of the functional and operational concepts of the 7300. Demonstrations using the Westinghouse 7300 Training System illustrate the functions of the 7300, and show how it provides protection, control, and indications for safe plant operation. The first day typically consists of lectures and discussions of the 7300 overview; cabinets, hardware, and components, a review of basic electronic theory, and specific card review. On day two the plant specific circuit card review is completed. An analysis of plant applications is started, using plant specific drawings where possible. Day two concludes with a review of the OPDT and OTDT circuitry. On day three, students perform OPDT and OTDT labs and troubleshooting. In addition, trainees will review the Pressurizer Level Control, and begin labs and troubleshooting on this circuit. Day Four completes the Pressurizer Level Control troubleshooting, then continues on with Steam Generator Water Level Control review, labs, and troubleshooting exercises. The instructor uses the final day for a review of the 7300 material that was presented during the week, and to administer a written examination. The trainer can also conduct an optional troubleshooting performance examination for qualification purposes. |
