Tests of cosmic ray radiography for power industry applications

Abstract

In this report, we assess muon multiple scattering tomography as a non-destructive inspection technique in several typical areas of interest to the nuclear power industry, including monitoring concrete degradation, gate valve conditions, and pipe wall thickness. This work is motivated by the need for radiographic methods that do not require the licensing, training, and safety controls of x-rays, and by the need to be able to penetrate considerable overburden to examine internal details of components that are otherwise inaccessible, with minimum impact on industrial operations. In some scenarios, we find that muon tomography may be an attractive alternative to more typical measurements.

Experiments on muon radiography with emulsion track detectors

“…Lately, the capabilities of muon radiography for nuclear reactor monitoring were actively developed [14,15]. The need for such a research became apparent after the devastating accident at the Fukushima-1 nuclear power plant in Japan [16,17] (see Fig.…”

Large Industrial and Natural Objects Investigation by the Muon Radiography on the Basis of Track Detectors

“…Up to date, in the world practice the research of various objects by the method of muon radiography the electronic equipment was often used, even it is much more cumbersome and complicated than the emulsion track detectors [9,10,[17][18][19][20]. Emulsion track detectors, in addition to small size and design simplicity, have today's best spatial resolution (<1 micron), large information capacity.…”

“…Muon radiography method has been already successfully used for nondestructive testing of large industrial facilities, such as bridges, dams, blast furnaces, etc. [9], for radiation monitoring of nuclear power facilities [10] and for large archaeological object radiography: the first successful archaeological research of Khafre pyramid in Egypt was carried out in the 70s of the 20th century by group of scientists under the leadership of Nobel laureate Luis Alvarez [11]. During last ten years physicists of Italy, Japan, Switzerland and other countries for these purposes have actively developed the muon radiography on base of track detectors with nuclear emulsions as a recording elements [8,[12][13][14][15], many model calculations and experimental measurements are made.…”
