Abstract
75903-Neutron radiography, which uses nuclear reactors and accelerators as sources of neutrons, has been demonstrated to be an excellent method for imaging high-density, thick objects for the detection of corrosion, voids, and cracks, particular in nuclear power plants. Unfortunately, no high brightness neutron sources exist that are portable, inexpensive and capable of neutron radiography in short imaging times. This project will develop an inexpensive, portable, high-intensity source that can be scaled to a high-brightness radiator capable of imaging with reasonable exposure times. The high brightness will be achieved by increasing the neutron production and by focusing the neutron-producing beam (e.g. D+ ions) onto a small diameter titanium anode. Phase I will: (1) analyze the required brightness and source size to achieve the imaging times and resolution needed for the nuclear industry, (2) establish the required performance parameters, such as resolution and contrast, for a portable neutron radiographic source, (3) create a prototype design, and (4) conduct preliminary imaging experiments using an existing neutron source. The design of a compact, fast thermal neutron radiography system in Phase I will lead to the construction of a commercial prototype in Phase II. Commercial Applications and Other Benefits as described by the awardee: A compact fast/thermal neutron source, capable of penetrating steel, lead or uranium, should improve the nondestructive evaluation of nuclear plants. Specifically, it could discover fatigue cracks, evaluate piping integrity without the need to remove insulation, and detect aging in polymeric cabling materials. The neutron radiography source also could serve the nondestructive testing need of aircraft, public utility, and petrochemical organizations.
