Nuclear analysis

Some 60 elements can be identified and quantified after having been transformed into radioisotopes by bombardment with particles. This particular labelling technique, whose sensitivity varies with the element (1000 ppm to ppb), is part of the field of multi-elemental nuclear analysis. Neutron activation is the most widely used of these techniques because it does not involve charged particles. 

The comprehensive reviews in Analytical Chemistry cover nuclear analysis with three of the more recent reviews on Nuclear and radiochemical analysis being by Ehmann and colleagues (Ehmann et al. 1990, 1992,... 

NDP is a prompt nuclear analysis technique, which employs a nuclear reaction that results in emission of charged particles with a specific kinetic energy. It is one of the most powerful non-destructive techniques for depth profiling of some light elements especially for and Li, which have very high thermal neutron capture cross-sections of 3837 and 940 barn respectively. 

PIGE or PIGME is a versatile non-destructive technique which is complementary to other ion beam techniques (especially particle induced X-ray emission, PIXE). It is the most common application of nuclear analysis. 

The mechanical design of the fuel and core for the Standard MHTGR is described in Section 4.2.4.1.1. The results of the nuclear analysis of the core (Section 4.2.5.2.1) provided the core power and flux distributions for the fuel performance analysis.
