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.

Standards and regulations in many countries discuss graded approach; some
even require it. Criteria or justifications for grading are commonly addressed.
Not much, however, is discussed about the methods that can be used to grade
a process once the criteria are met.
This webinar will remove any mystery associated with graded approach. Mr.
Chermak asserts there are only two ways to grade one’s approach to Quality
Assurance — and they are very simple.
Join us for an interactive discussion of this topic! We look forward to your
company while we learn about and delve into graded approach.

The post-war dawn of ‘The Atomic Age’ promised abundant energy and prosperity. However, questions around safety and economic viability contributed to nuclear fission going out of vogue by the late 1980s, culminating in the weekly lampooning of nuclear power on The Simpsons.
Today, the new urgency to decarbonize has put nuclear fission back on the table. What has changed on the technical front that might make it safer? Can it be economically viable compared to solar and wind power? Will people want a nuclear fission reactor in their town? Will fission power be necessary for us to reach our climate objectives?
We are in the middle of a shift in expert opinion on the viability of nuclear fission power. Join our panel of experts Wednesday, August 4 at 3 pm ET/12 pm PT to understand the current thinking around nuclear fission in relation to decarbonization.

In Service Inspection is a major challenge to consider for future Generation IV Reactors safety. Therefore, a large focus of R&D work has been performed since 2010 in France for the Sodium Fast Reactor systems (SFR), mainly dedicated to the inspection of reactor block structures, primary components and circuits, and Power Conversion System main components (Heat Exchangers). In Service Inspection requirements have to be taken into account since the early preconceptual design phase, then consolidated through the basic design phase with more detailed specifications leading to increase the inspection tools ability for immersed sodium structures of SFRs, at about 200°C (shut down conditions). Inspection within the main vessel should be performed either with transducers immersed in sodium (with associated in sodium robotics) and with transducers located out of sodium medium. Nondestructive Examination, Telemetry and Imaging are qualified with experimental in-water and then in-sodium testing, using
ultrasonic transducers. Experimental results are then compared to simulations using French CIVA software platform results. Repair was also part of this program, with laser system development. This webinar provides a technical overview of this
ISI&R program that involves specific international collaborations done through GENIV mainly. Of course, it also benefits to other Gen4 systems.

The development of critical design criteria for new advanced reactor systems, components, and materials requires an understanding of both fabrication and the irradiation environment during normal operating and accident conditions. Next-generation researchers and designers are therefore challenged not only by demands for improved performance, they must also work to shorten the development and commercialization lifecycle for new nuclear reactors and systems to remain competitive. This provides unique and exciting opportunities for all contributors to this field of study. This presentation will offer a strategic overview of the impact that advanced manufacturing has on the lifecycle of new generation reactors. By evaluating state-of-the-art practices found in other large manufacturing industries, this presentation provides an overview of major innovation areas that are considered to benefit the GEN-IV systems (SFR, GFR, LFR, FSMR...). Synergetic advanced manufacturing approaches beneficial to the collective GEN-IV systems, with some examples of differentiating approaches necessary for specific reactor designs, are discussed. Furthermore, new paradigms in licensing approaches for additively manufactured parts will be discussed.

WASHINGTON – The Nuclear Innovation Alliance (NIA) invites you to a webinar on Wednesday, May 19th about the release of a new report “Unlocking Advanced Nuclear Innovation: The Role of Fee Reform and Public Investment.” As multiple advanced reactor vendors enter the licensing process to build first-of-a-kind demonstration projects, issues with the NRC's current user fee cost recovery model could slow innovation and raise regulatory costs. Importantly, reliance on applicant fees limits the ability of the NRC to hire and train staff ahead of expected applications, reducing regulatory efficiency.
NIA's new report explores the history of the fee system, identifies how the fee model can inhibit advanced nuclear innovation, and compares to regulatory models in other industries and countries. It includes recommendations to strenghten the NRC, reduce barriers for advanced reactor applicants, and to ensure advanced reactors can provide a timely contribution to climate mitigation.
The webinar will consist of a virtual panel discussion moderated by former NRC Commissioner Stephen Burns, Senior Fellow at Third Way, with panelists Alex Gilbert of the Nuclear Innovation Alliance, Caroline Cochran of Oklo, and Peter Hastings of Kairos Power. The webinar will discuss the report and its findings, as well as discuss the impacts of user fees on advanced nuclear innovation more broadly.
