Underwater Integrated Measurement System for Fuel Assemblies
An underwater integrated measurement system for in-service fuel assemblies in spent fuel pools, using underwater image-vision technology to inspect geometric dimensions, appearance deformation and oxide film thickness without contact.
Product Overview
▅ Core Features
Adapted to underwater radiation environments: The system supports online inspection without disassembling the fuel assembly, helping protect component integrity and operational safety.
Full-dimensional inspection coverage: It integrates measurement of geometric dimensions, appearance deformation and oxide film thickness to support comprehensive condition assessment.
Image-vision measurement technology: Non-contact underwater visual measurement reduces manual intervention, improves data consistency and avoids secondary impact on the fuel assembly.
Complete assembly-size coverage: The system measures key indicators including assembly length, rod length, upper/lower nozzle clearance, rod pitch and grid width.
▅ Key Technical Parameters
Length measurement accuracy: 0.5 mm
Nozzle spacing measurement accuracy: 0.2 mm
Rod pitch measurement accuracy: 0.2 mm
Oxide film measurement accuracy: 5 μm
▅ Applicable Industries
Shipbuilding and nuclear industry.
▅ Application Value
The system provides accurate, traceable underwater inspection data for fuel assembly operation and maintenance. Non-contact measurement and full-dimensional coverage support nuclear facility safety assessment while reducing operational risk.
