SPN DETECTORS

Self-Powered Neutron Detectors

SPN-detectors are designed for the detection of

thermal neutrons within the core of the reactor. These

detectors generate a current proportional to the

neutron  ux density without applying an external

voltage source.

In general, the detector current of these detectors is

caused by the emission of beta radiation (electrons)

from the target material which gets activated by

neutrons. Therefore, besides the name SPN-detector

(Self-Powered Neutron detector), also the name n,ß-

detector (neutron-beta-detector) is in use.

APPLICATIONS

• Operational process monitoring

○ Detection and measurement of the thermal

neutrons inside the reactor core for neutron  ux

distribution monitoring and monitoring of neutron

 ux peaks
