Non-Destructive Determination of Reactor Pressure Vessel Neutron Exposure by Continuous gamma-Ray Spectrometry

摘要

Neutron induced radiation damage experienced by the pressure vessel of a power reactor can be a controlling factor in defining the effective life of plant operation. As a consequence, methods of quantifying the neutron exposure fluence of reactor pressure vessels are of worldwide interest. To this end, a new nondestructive method of reactor pressure vessel neutron dosimetry is advanced. It is based on the observtion of characteristic gamma-rays emitted by activation products in the reactor pressure vessel with a unique Si(Li) Compton continuous gamma-ray spectrometer. 5 references (extended abstract).
