Mini-size fuel plates with monolithic U-10Mo and Zr coating applied by PVD were successfully irradiated and showed stable and predictable swelling behavior in the EMPIrE test. As a next step, the FUTURE-MONO-1 irradiation test is designed to demonstrate this fuel’s performance in full-size geometry and thus qualify it generically for the conversion of European research reactors to low-enriched uranium fuel.As part of this scale-up, Framatome-CERCA demonstrated their capabilities for U-Mo full-size foil fabrication by rolling and laser-cutting, while TUM’s pilot PVD device is able to coat the full-size LEU foils produced this way with a Zr diffusion barrier.

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. [...]

The determination of nuclear structure parameters such as gamma transitions, level scheme, nuclear level density and radiative strength functions is one of the most important tasks in low-energy nuclear physics. The two-step gamma cascades method based on detection of gamma coincidences following neutron capture, ie. [...]

Over the past decade, Oak Ridge National Laboratory developed neutron capabilitiesat both the High Flux Isotope Reactor and the Spallation Neutron Source. A broad scientificportfolio has flourished at both facilities such that a new facility named VENUS is currentlyunder construction at the Spallation Neutron Source [...]
