Boron meter system

Description
This Boron Meter System is designed to monitor continuously the boron concentration in the water circulating in the LWR primary system, and its performance is as good as the similar product produced in other countries, which is validated by the stable and reliable operation in nuclear power plants. NPIC provides the supply of this product, the modification of this system and equipment, and training of operators and maintenance staff.

Characteristics
This system is designed based on the characteristics of B10 to absorb the slow neutron. It can continuously measure and display the boron density in the primary water in the pressured reactor nuclear power plants, and gives an alarm when the boron density is over-diluted.
