Abstract
A method for assaying a wall of a pressure tube for a nuclear reactor is disclosed. The wall has a matrix material and deuterium nuclei in the matrix material. The method includes: (a) transmitting gamma rays into the matrix material to induce photodisintegration of at least some of the deuterium nuclei, whereby reaction particles of the nuclei are emitted from the wall; (b) detecting at least some of the reaction particles emitted in step (a) using a particle detector; and (c) generating particle signals in response to detecting the particles in step (b).

A method for assaying an object having a matrix material and target nuclei in the matrix material, the method comprising:
- a) subjecting an n-gamma radiator to a neutron flux to induce an n-gamma reaction, whereby gamma rays are emitted from the radiator;
- b) transmitting the gamma rays emitted from the radiator in step (a) into the matrix material to induce photodisintegration of at least some of the target nuclei, whereby reaction particles of the nuclei are emitted from the object;
- c) detecting at least some of the reaction particles emitted from the object in step (b) using a particle detector;
- and
- d) generating particle signals in response to detecting the reaction particles in step (c).
