As the title says, Molten Salt Reactors (MSR) utilize molten salt in their core. Especially, when it is used as a fuel carrier, it provides enormous designing freedom. Consequently, there are many concepts available in the literature; some more matured than others. Recently there was a common effort at IAEA to classify these concepts and create MSR taxonomy. This taxonomy will be briefly introduced in the seminar together with the reactor physics characterization of the major MSR classes and families. Particular MSR features will be discussed and listed together with the involved families. The fuel cycle performance will be evaluated from neutronics perspective. It will include discussion about cross- section of applicable material for MSR construction. Several MSR families will be classified according to the breeding gain and applicable fuel cycles. Last but not least, salt composition and distribution in the MSR system during its operation will be presented together with an initial assessment of possible radionuclides release during accidental conditions.

Please join the U.S. Department of Energy (DOE), Office of Nuclear Energy for a webinar on its consent-based siting funding opportunity announcement (FOA). On Oct. 3, 2022, from 3 p.m. - 4 p.m. EST, hear from DOE Assistant Secretary for Nuclear Energy, Dr. Kathryn Huff, and DOE Deputy Assistant Secretary for Spent Fuel and Waste Disposition, Sam Brinton.

The purpose of this webinar is to share progress on DOE's consent-based siting efforts and answer questions about the recent funding opportunity announcement. The $16 million FOA was issued to support public engagement and dialogue with DOE regarding a consent-based process to site one or more federal consolidated interim storage facilities for the nation’s spent nuclear fuel.

In this Webinar, development of ISI rules for SFRs using the System Based Code (SBC) concept is introduced. The SBC concept consists of three parts: 1) design to reliability target that must be met throughout the service life, 2) margin exchange among the various technical areas of concern such as design, inspection, fabrication, and fitness for service, and 3) expand technical options by the timely adoption of newly developed technologies that are not in current codes and standards. Such a flexible and consistent concept is suitable to develop ISI rules by taking account of individual features of SFR plants. A unique logic flow to determine ISI requirements by using reliability targets for components is discussed, and the procedure to derive the reliability targets from plant safety requirements and to evaluate corresponding structural reliability is presented.

The Nuclear Power Institute of China has developed many small and medium (SMR) reactors including those used for nuclear seawater desalination, nuclear district heating, and nuclear-powered commercial ships, multi-purpose small modular pressurized reactors. Developing nuclear energy is a measure of meeting national economic development and satisfying the need for energy conservation and reduction of emissions. Large size nuclear power units are less suitable to regional networks and non-electric fields, highlighting the importance of studying small and medium reactors. Small reactors are also in high demand for developing countries and the vast Midwest of China. Domestic cities and regions are also in urgent need of nuclear energy for heating, desalination, and district heating.

Molten salt reactors (MSRs) are being considered as one of the potential nuclear options to meet future energy demands. While the MSR designs differ from the more traditional light water reactor, many of the waste streams are similar between the concepts. Other streams differ drastically. This presentation outlines strategies for the treatment and processing of MSR-type wastes from concepts of reconditioning and recycle of certain components to partitioning and direct immobilization of other waste components. The primary focus will be on the management of fuel salt related wastes while other streams unique to MSRs are also briefly discussed.

Austenitic stainless steels are widely used as in-core materials in current nuclear systems, due to a combination of corrosion resistance, ductility, and other mechanical properties. However, in the next generation nuclear systems that will be operated at higher temperature and higher level of neutron irradiation, the use of austenitic stainless steels is largely avoided mostly due to poor void swelling resistance. In this regard, our research group developed an austenitic SS with uniformly distributed nanosized NbC precipitates, named as ARES-6P, by controlling chemical composition and thermo-mechanical processing. To demonstrate the radiation resistance, heavy ion irradiation was performed at high temperatures to the damage level of ~200 displacement per atom (dpa). The measured void swelling of ARES-6P was 2‒3%, which was considerably less compared to commercial 316 stainless steel and comparable to ferritic martensitic steels. In addition, the increment of hardness measured by nano-indentation was much smaller for ARES-6P compared to 316 stainless steel. Though some nanosized NbC precipitates were dissociated under relatively high dose rate (~5.0 × 10-4 dpa s-1), a sufficient number of NbC precipitates remained to act as sink sites for the point defects, resulting in superior radiation resistance. Both significantly less void swelling and less irradiation hardening indicate the superior irradiation resistance of ARES-6P for the application of next generation nuclear systems. Register NOW at:

Join us for a national workshop exploring strategies for and the many benefits of repurposing legacy fossil fuel infrastructure, including closed coal mines, coal power plants, and orphaned oil and gas wells.

Leveraging and transforming legacy fossil fuel infrastructure creates the opportunity for a skilled workforce to access new sources of high-quality jobs and for states and communities to increase tax revenues. As clean energy, manufacturing, and other innovative companies grow, energy communities are an attractive option for locating new and expanding operations because they often offer:

A skilled workforce with knowledge of industrial operations
Entrenched community relationships
Access to rail lines, ports, highways, and other distribution infrastructure
Electrical interconnect equipment and direct grid connections
Industrial land, facilities, and potentially even site and permitting licenses
Register for this half-day workshop featuring expertise on site remediation and reclamation, worker training and upskilling of dislocated workers, and the broad range of options for capitalizing on existing fossil fuel infrastructure.
In the industry and especially in the nuclear field, simulation software plays an important part on the study of new prototypes, as building scale 1 prototype is both complex and expensive. To assess new design options and validate associated simulation software, most experiments are performed on small-scale mock-ups. However, distortions of a studied phenomenon can occur from a small-scale model to a prototype: this is known as scale effects. Without understanding of these effects, results from models cannot be transposed to the prototype scale and numerical results cannot be validate either.
In the French SFR project, an important problematic is the raise of the core jets in the upper plenum for specific operating conditions. When these jets raise, the flow pattern in the vessel is modified and leads to thermal fluctuations reducing the lifetime of the reactor’s components because of thermal fatigue. While this raise can be observed on small-scale mock-up, it is important to be able to characterize both this phenomenon and its transposition. For this purpose, Benjamin Jourdy works on a methodology based on bibliography synthesis and experimental results, leading to the conception of a new mock-up dedicated to this study. Register Here:

The ESFR-SMART project is what in the Anglo-Saxon world is called a “working horse" or a “concept car”. Its role is to introduce, outside any constructive planning, new ideas for the future, which can be valuable guides for R&D. Unlike in an “industrial” project, which initially had a construction schedule, one can introduce innovative ideas, even if their lower technological-readiness level would require development and time. For these new ideas, research and first calculations were also performed during the project, to check their general feasibility and the absence of major impossibilities.

The presentation will show the design proposition for this SFR reactor including the
experience feedback from European experience on Phénix, Superphénix, EFR and ASTRID. This design includes all improvements in response to the last safety rules issued after the Fukushima incident. Finally, the first calculations performed for the design validation are also explained with the necessary R&D.
