The HFIR, RHF, and FRM II reactors represent a particular class of Research and Test Reactors that provide some of the most intense and continuous neutron fluxes for science, industry, and medical applications. These high-performance reactors have achieved compact cores by operating with Highly Enriched Uranium fuel (HEU, 235U/U ≥ 20 wt. [...]

A gamma-irradiation facility is constructed for irradiations of samples in the spent fuel elements at the FRM II. It consists of a double-walled watertight sample container and a positioning device to adjust the sample position for a homogeneous irradiation. [...]

The Cold Neutron Source is arguably the most important of the secondary sources of FRM II. When its damage was diagnosed and confirmed, it had to be pulled from the rector in order to allow for continuation of the reactor operation. [...]

Abstract: Meanwhile since more than three decades smart micro- and nanogels are studied and the number of publications in this area of research is steadily growing. This year to date (May 2021) already more than 400 articles were published on this topic. [...]

For chemical analysis, reactions of neutrons with atomic nuclei can be used to induce a radiation characteristic of the element. This is the basis for neutron activation analysis (NAA) and prompt gamma activation analysis (PGAA), two established methods for determining the elemental bulk composition in highly different matrices. [...]

Neutrons are versatile probes for the non-destructive examination of various materials. To introduce the following chapters on the applications and methods, we give a general overview of the fundamental properties of neutrons and the ways of their production in research institutes. [...]

Large-scale analytical research infrastructures (ARIs) provide unique capabilities tostudy materials and living matter at levels far beyond those of conventionaltechniques. The x-ray and neutron analytical research infrastructures (synchrotron,free-electron laser, nuclear reactor, and spallation neutron sources) are at the centreof the ARI family and provide a vast range of techniques and skills made availableto researchers in academia and industry alike to study, probe, and monitor materialsunder static as well as real manufacturing and working conditions.
