The Status and Prospect of Reactor Neutron Detector
Abstract:Reactor neutron detector is the necessarysafety device for nuclear plant. The detection principles of several in-core and ex-core neutron detectors are introduced in this paper,and they are compared in the aspects of advantages, applied range, applied status and disadvantages;The main challenges for the new generation reactors are also summarized, and it shows the most important one for the present neutron detector is material problem due to the wore condition of the new generation reactor, which determines the key parameters, such as high temperature resistance, lifetime, sensitivity and radiation resistance.Finally,the development status and prospects of neutron detectors for the new generation reactors are outlined.
Keywords: reactor neutron detector new generation reactor
