½ð²©ÌåÓý

Background

½ð²©ÌåÓý has provided training services for boiling water reactor (BWR) plants since 1980. These training programs combine formal classroom instruction with hands-on lab exercises to maximize student learning and skills development.

Description

½ð²©ÌåÓý has a full-depth wet vessel mockup at the Chattanooga, Tennessee (USA), BWR Service Center, complete with a fully operational fuel-handling platform. The service center mockup also includes a mock spent fuel pool (SFP).

The reactor vessel mockup has the following components:

• One-eighth section full-scale in-vessel mockup
• Actual reactor components Top guide
• Fuel supports
• Control rod
• Jet pumps
• In-core instruments
• Control rod blade guides
• Dummy fuel assemblies
• Fuel-handling platform Vessel-servicing aids, grapples and cameras

The Chattanooga BWR Service Center includes a full-size, under-vessel mockup complete with a carousel, a leveling tray, a control rod drive (CRD) travel path and an A-frame for loading and unloading mock CRDs.

½ð²©ÌåÓý also has a fully equipped and mobile BWR trailer for hands-on CRD training.

The ½ð²©ÌåÓý mobile CRD mockup trailer is a self-contained mockup of the CRD and under-vessel area of the BWR (two through six) reactor vessel. It is designed so that it can be easily transported and set up at the customer’s facility. ½ð²©ÌåÓý trainers can use the ½ð²©ÌåÓý Model 2 CRD exchange equipment or the customer-supplied non-contaminated exchange equipment.
