“…ELECTRA (European Lead Cooled Training Reactor) 14,15 concept has been developed for the acquisition of LFRs' operation technology and also as an educational and training facility by the KTH Royal Institute of Technology (KTH) in Sweden. Derived from the research on LFRs made at KTH, SEALER (Swedish Advanced Lead Reactor) 16‐18 has been designed by LeadCold Reactors Company mainly to serve the needs of the power production and mining operations market in Arctic regions of Canada. Hydromine Nuclear Energy (HNE) of Luxembourg has carried out the design and research work of an amphora shaped lead‐cooled fast reactor LFR‐AS‐200 5 .…”

Summary Lead‐based fast reactor is one of the most promising fourth‐generation nuclear energy systems. Fuel assembly design is a key technology for the research and development of lead‐based fast reactor. The current status of typical lead‐based reactors and fuel assembly design schemes in the world are reviewed in this paper, and also the key technical parameters and design features of fuel assembly are summarized, with the advantages and disadvantages discussed. A hexagonal fuel assembly that can achieve both “passive” and “active” axial positioning by the gravity of ballast unit and mechanical locking device proposed by the nuclear fuel assembly research group of China initiative Accelerator Driven System project at Institute of Modern Physics has been emphatically introduced. It is expected that this paper can provide certain supporting data and reference solutions for the further design and development of fuel assembly for lead‐based reactor.

“…LeadCold Reactors, a spin-off company of KTH Reactor Physics Division, is developing LFRs in the SMR category. Their SwEdish Advanced LEad Reactor (SEALER) is designed to produce electricity in remote, off-grid regions, such as the Canadian Arctic [2]. A variant of SEALER is currently being developed for the UK, named Small, Economic and Agile LEad-cooled Reactor for the UK (SEALER-UK).…”

Investigation of a Self-Actuated, Gravity-Driven Shutdown System in a Small Lead-Cooled Reactor

Passive safety systems in a nuclear reactor allow to simplify the overall plant design, beside improving economics and reliability, which are considered to be among the salient goals of advanced Generation IV reactors. This work focuses on investigating the application of a self-actuated, gravity-driven shutdown system in a small lead-cooled fast reactor and its dynamic response to an initiating event. The reactor thermal-hydraulics and neutronics assessment were performed in advance. According to a first-order approximation approach, the passive insertion of shutdown assembly was assumed to be influenced primarily by three forces: gravitational, buoyancy and fluid drag. A system of kinematic equations were formulated a priori and a MATLAB program was developed to determine the dynamics of the assembly. Identifying the delicate nature of the balance of forces, sensitivity analysis for coolant channel velocities and assembly foot densities yielded an optimal system model that resulted in successful passive shutdown. Transient safety studies, using the multi-point dynamics code BELLA, showed that the gravity-driven system acts remarkably well, even when accounting for a brief delay in self-actuation. Ultimately the reactor is brought to a sub-critical state while respecting technological constraints.

“…In Europe, a lead-based reactor was rapidly developed under the framework of science project. In addition, a small modular lead-based reactor, SEALER (Wallenius et al, 2018;LeadCold Reactors Company, 2022), was designed by Swedish LeadCold Company for polar region application. Furthermore, an experimental reactor MYRRHA (Abderrahim and D'hondt, 2007), demonstration reactor ALFRED (Frogheri, 2013;Alemberti, 2020), and prototype reactor ELFR (Frogheri, 2013) have been under research and development.…”

Neutronics performance improvement based on the small lead-based fast reactor SLBR-50

The design of high-performance lead-based fast reactors (LFRs) has become a hotspot in the advanced reactor system. This study evaluates the neutronics performance improvement based on the small LFR SLBR-50. Parameter sensitivity analyses are conducted, including height-to-diameter ratio (H/D), reflector assembly arrangement, and pitch-to-diameter ratio in fuel assembly, fuel material, and fuel enrichment partitioning. Numerical results of eigenvalue in burnup procedure, assembly power distribution, and energy spectrum are analyzed using the Monte-Carlo code RMC. Our findings indicate that the fuel material, fuel partitioning, and H/D are the three most important factors in LFR design. The neutronics performance analyses will assist in LFR design.
