coupling heat storage to nuclear Reactors for variable electricity output with baseload Reactor Operation
The Electricity Journal, 2018Co-Authors: Charles Forsberg, Stephen Brick, Geoffrey HaratykAbstract:Abstract Nuclear Reactors produce heat and thus can couple to heat storage systems to provide dispacthable electricity while the Reactor operates at full power. Six classes of heat storage technologies couple to light-water Reactors with steam cycles. Firebrick Resistance-Heated Energy Storage (FIRES) converts low-price electricity into high-temperature stored heat for industry or power. FIRES and brick recuperators coupled to nuclear brayton power cycles may enable high-temperature Reactors to buy electricity when prices are low and sell electricity at higher price.

demand driven salt clean up in a molten salt fast Reactor defining a priority list
PLOS ONE, 2018Co-Authors: Bruno Merk, Dzianis Litskevich, Robert Gregg, Andrew R MountAbstract:The PUREX technology based on aqueous processes is currently the leading reprocessing technology in nuclear energy systems. It seems to be the most developed and established process for light water Reactor fuel and the use of solid fuel. However, demand driven development of the nuclear system opens the way to liquid fuelled Reactors, and disruptive technology development through the application of an integrated fuel cycle with a direct link to Reactor Operation. The possibilities of this new concept for innovative reprocessing technology development are analysed, the boundary conditions are discussed, and the economic as well as the neutron physical optimization parameters of the process are elucidated. Reactor physical knowledge of the influence of different elements on the neutron economy of the Reactor is required. Using an innovative study approach, an element priority list for the salt clean-up is developed, which indicates that separation of Neodymium and Caesium is desirable, as they contribute almost 50% to the loss of criticality. Separating Zirconium and Samarium in addition from the fuel salt would remove nearly 80% of the loss of criticality due to fission products. The theoretical study is followed by a qualitative discussion of the different, demand driven optimization strategies which could satisfy the conflicting interests of sustainable Reactor Operation, efficient chemical processing for the salt clean-up, and the related economic as well as chemical engineering consequences. A new, innovative approach of balancing the throughput through salt processing based on a low number of separation process steps is developed. Next steps for the development of an economically viable salt clean-up process are identified.

progress in reliability of fast Reactor Operation and new trends to increased inherent safety
Applied Energy, 2015Co-Authors: Bruno Merk, Alexander Stanculescu, P Chellapandi, R N HillAbstract:The reasons for the renewed interest in fast Reactors and an overview of the progress in sodium cooled fast Reactor Operation in the last ten years are given. The excellent Operational performance of sodium cooled fast Reactors in this period is highlighted as a sound basis for the development of new fast Reactors. The Operational performance of the BN-600 is compared and evaluated against the performance of German light water Reactors to assess the reliability. The relevance of feedback effects for safe Reactor design is described, and a new method for the enhancement of feedback effects in fast Reactors is proposed. Experimental Reactors demonstrating the inherent safety of advanced sodium cooled fast Reactor designs are described and the potential safety improvements resulting from the use of fine distributed moderating material are discussed.

lessons learned from sodium cooled fast Reactor Operation and their ramifications for future Reactors with respect to enhanced safety and reliability
Nuclear Technology, 2008Co-Authors: J Guidez, P Chellapandi, L Martin, S C Chetal, Baldev RajAbstract:Eighteen sodium-cooled fast Reactors (SFRs), a number that includes Reactors in Operation or shut down, have provided 388 Reactor-years of operating experience to date. This paper summarizes the important incidents related to fast Reactor sodium components and systems. The solutions incorporated, based on experience, analysis, experimental tests, and research and development for past and current SFRs, are described. The paper also describes lessons learned for future SFRs.
