Monitoring the exchange of fuel rods in

nuclear power stations to detect damages


Replacing fuel rods in a nuclear power station is a critical process,

especially inserting new rods. Even small deviations from the ideal

position lead to malfunctions and the corrective actions are time

consuming as well as expensive.

Conventional vision systems with standard video framing rates (25

frames/sec) used today for monitoring purposes are too slow to reveal

details of the causes for possible damages. Cameras with substantially

higher frame rates (‘highspeed cameras’) cannot record

the complete process due to a limited sequence length.


A high speed video system with 200 frames/sec (= 8 time faster than

standard PAL video) and the capability to stream for several hours

provide slow motion footage covering the full process. The high

speed video systems works with 2 compact camera heads, covering

all sides of the inserting rod.

Customer benefits

The operator of the Mass Rapid Transport system benefits from advantages

like the following:

• Slow motion image sequence to capture the shortest incidents.

• Slow motion allows to indicate the reasons why an incident

happened (thus allowing to correct and improve the process).

• All sides of the fuel rod are covered by a 2-camera system

• Sequence length to cover the complete process, user-selectable

between minutes to hours

• High image quality to detect even small details

• Post-processing the video sequence by a Motion Analysis
