Neutron Flux Monitoring System

The neutron  ux monitoring system proTK™ com-

bines long term experience in design and manu-

facturing of both detectors and signal processing

electronics. These products are strictly oriented to

the highest level of safety relevance and reliability and

are quali ed by several type tests and proven by an

excellent operational experience.

The system proTK™ covers the requirements for

measuring equipment used for the reactor protection

system according to IEC 61226 cat A.

APPLICATIONS

• Operational process monitoring

○ Measurement and monitoring of the neutron  ux

density from start-up range to the power range for

research reactors and power reactors
