| The 5-day RVLIS Hydraulics training program is designed to provide plant I&C technicians and engineers the skills and information necessary to operate, maintain, and troubleshoot this system. This is accomplished through a combination of classroom and hands on laboratory maintenance and troubleshooting exercises using equipment similar to that found in the plant. Hydraulic training equipment is available to allow students to perform hands on operation of the hydraulic system including alignments and system filling, and return the system to operational status. The RVLIS Hydraulics course begins with an overview of the basic purpose and operation of the RVLIS system. After completing the overview and functional description of the system, the course focuses on the hydraulics portion of the system. During this portion of the course, the students will be provided with information pertaining to the construction and operation of the components that comprise the hydraulics portion of the RVLIS system including the sensor bellows, hydraulic isolators, differential pressure transmitters and Magnex valves. Laboratory sessions will be used to demonstrate how to properly operate the Magnex valves, test system integrity, evaluate hydraulic isolator performance and calibrate the differential pressure transmitters. Using the hydraulics laboratory rig, the students will learn how to perform a vacuum fill of the system. After the students have been exposed to the hydraulic components found in the RVLIS system, the students are provided with a detailed understanding of the hydraulic operation of the system. This portion of the course is introduced by covering system piping diagrams and interconnecting wiring diagrams and followed by additional laboratory exercises during which the students are asked to calibrate the cards in the cabinet until the system is functional and provides proper indications. These exercises serve as a review of the circuit cards and the overall RVLIS system. The remainder of the course is used to demonstrate the response of the system to various faults. The hydraulics training rig trainer is used throughout the course to provide the students with as much hands on training as possible. Additionally, plant specific procedures and system documentation, such as alignments and vacuum fill procedures, will be utilized as much as possible during the laboratory exercises. One examination will be used to test the students understanding of the hydraulic system. The examination questions are based on the learning objectives used in the course. The exam is given at the end of the week. |
