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.
