Remote Visual Inspection Equipment Overview
BWXT's remote visual inspection services are crucial for nuclear facilities to ensure the integrity and safety of their equipment. The equipment includes a range of tools such as inner tube bundle inspection cameras, annulus inspection cameras, inspection crawlers, retrieval kits, delivery tubes, and video recording equipment. These tools allow for thorough inspections of critical components like tubesheets and annulus regions to verify cleanliness requirements, identify foreign objects, and perform retrievals when necessary. The use of video monitors and cables enables real-time viewing of inspection activities, enhancing the overall efficiency and accuracy of the process.
Annulus Inspections and NTL Inspections
Annulus inspections are essential for verifying the cleanliness of tube sheet annulus areas. BWXT's inspection camera with integrated lighting and retrieval guides allows inspectors to navigate through handholes and conduct detailed inspections. Similarly, NTL inspections are crucial for ensuring the cleanliness of NTL regions and bundle regions to identify any foreign objects present. The use of lancing rails as delivery systems streamlines the inspection process, reducing setup and removal times significantly. With specialized cameras housed within the inspection unit, inspectors can perform accurate and efficient inspections while minimizing the risk of damage or loose parts.
Preheater Inspection and FOSAR
BWX Technologies' remote visual inspection services also extend to preheater and feedwater box region inspections. Video probes and delivery tubes are utilized for these inspections, with retrievals conducted using tubesheet elevation retrieval tooling. These inspections are crucial for ensuring the proper functioning and maintenance of key components in nuclear facilities. By incorporating field-proven equipment and specialized tooling, BWXT's services provide a comprehensive solution for inspecting and maintaining critical infrastructure.
Qualification and Validation Process
BWX Technologies' rigorous qualification and validation process ensure the reliability and effectiveness of their remote visual inspection services. Mock-up inspections within tube bundles and validation of in-bundle tube lanes are conducted to identify foreign materials and verify performance criteria. The process includes inspection of both hot leg and cold leg sides, ensuring thorough coverage of all critical areas. By validating the inspection and retrieval capabilities of annulus and NTL regions, BWXT guarantees the readiness and efficiency of their services for on-site execution, providing peace of mind to nuclear facility operators.
