A microreactor based on high-temperature gas reactor (HTGR) technology is a very promising advanced reactor with inherent safety, and it can couple with a closed Brayton cycle for higher efficiency. Since dynamics characteristics are fundamental to analyzing a power generation system and a reactor is the main source of the dynamics characteristics of a system, it is necessary to study a microreactor model suitable for system analysis. The main goal is to simulate the performance of the previously mentioned integrated system, focusing on the details of the power conversion unit while still ensuring acceptable calculation times. Hence, a simplified reactor model is needed that could supply sufficiently accurate values of pressure drop and heat transfer across the core. In this paper, by simplifying the physical processes in a microreactor, a dynamic model described by differential algebraic equations is obtained based on the lumped parameter modeling methodology and the basic conservation of fluid mass, momentum, and energy. Coupling thermal hydraulics with neutron kinetics, the temperature coefficient of reactivity and xenon poisoning are considered. Finally, the model is programmed and calculated using Modelica language. The transient responses of the main parameters under typical perturbations are analyzed, and the results show that the responses are correct. Because of the effect of reactivity feedback, fluctuations of the main parameters caused by microperturbations eventually tend to stabilize. In addition, the effects of negative reactivity introduced by xenon poisoning under two typical dynamic processes are analyzed. In power regulation, excess reactivity is required to compensate for the negative reactivity introduced by 135Xe. The model and results can properly predict the systematic parameters and serve as a basis for system analysis of microreactor coupling with the helium closed Brayton cycle.}, + keywords = {microreactor,Modelica language,simplified model,System analysis} +} + @article{gentonClassesKernelsMachine2001, title = {Classes of {{Kernels}} for {{Machine Learning}}: {{A Statistics Perspective}}}, shorttitle = {Classes of {{Kernels}} for {{Machine Learning}}}, @@ -7771,6 +7807,24 @@ for defect classification of TFT–LCD panels.pdf} abstract = {This video walks through a controller design for an active suspension system.

The codes developed under the U.S. Department of Energy Office of Nuclear Energy Advanced Modeling and Simulation (NEAMS) program provide flexibility in terms of geometry modeling and multiphysics coupling and are particularly well suited for modeling novel microreactor concepts. To test the maturity of these codes, this paper introduces a conceptual heat pipe microreactor (HP-MR) designed to gather various technologies of interest to microreactor developers such as control drums, heat pipes, and hydride moderators. The objective of this effort is to demonstrate NEAMS tools capability to perform high-fidelity multiphysics simulations, using coupled neutronics (via the Griffin code), heat conduction (via the BISON code), heat pipe modeling (via the Sockeye code), and hydrogen redistribution in hydride metal moderator (via the SWIFT code). Codes are coupled in-memory through the Multiphysics Object-Oriented Simulation Environment (MOOSE) framework, which permits flexible multiphysics data transfer schemes. The analysis confirmed two key aspects of the HP-MR concept: (1) its ability to follow the power load requested from the heat pipe and (2) its ability to avoid heat pipe cascading failure unless designed with high power close to operating failure limits of its heat pipes. The developed computational model was distributed publicly on the Virtual Test Bed for training purposes to accelerate adoption by industry and to provide a high-fidelity multiphysics solution for benchmarking against other tools. Additional multiphysics analyses including other transients and coupled physics were identified as necessary future work, together with a focus on validating multiphysics behavior against experiments.}, + keywords = {heat pipe,Microreactor,multiphysics} +} + @video{stevebruntonControlBootcampCautionary2017, entrysubtype = {video}, title = {Control {{Bootcamp}}: {{Cautionary Tale About Inverting}} the {{Plant Dynamics}}}, @@ -12386,6 +12456,24 @@ Subject\_term: Careers, Politics, Policy}, file = {/home/danesabo/Zotero/storage/CI4DN5JM/Ter Beek et al. - 2022 - Formal methods and tools for industrial critical s.pdf} } +@article{testoniReviewNuclearMicroreactors2021, + title = {Review of Nuclear Microreactors: {{Status}}, Potentialities and Challenges}, + shorttitle = {Review of Nuclear Microreactors}, + author = {Testoni, Raffaella and Bersano, Andrea and Segantin, Stefano}, + date = {2021-08-01}, + journaltitle = {Progress in Nuclear Energy}, + shortjournal = {Progress in Nuclear Energy}, + volume = {138}, + pages = {103822}, + issn = {0149-1970}, + doi = {10.1016/j.pnucene.2021.103822}, + url = {https://www.sciencedirect.com/science/article/pii/S0149197021001888}, + urldate = {2025-01-21}, + abstract = {Nuclear energy is being reconsidered worldwide as a low-carbon and dispatchable energy source. Following the development of Small Modular Reactors (SMR) to reduce the capital costs and increase the safety of new nuclear power plants, microreactors are being designed by several companies. Microreactors are usually defined as SMR with a power output in the range 1–20 MWe. They can operate as part of the electric grid, independently from the electric grid or as part of a microgrid to produce electricity and process heat. In the present paper, some microreactors at an advanced design stage are presented: eVinci™, Aurora, Holos Generators, Xe-Mobile, NuScale, Sealer, U-Battery and Micro Modular Reactor. The main applications of microreactors and the technology features are then discussed to present the main potentialities and challenges. The main advantages are the small size, the simple plant layout and the fast on-site installation. The main challenges are the limited fuel availability, the security and proliferation risk and the licensing process. Finally, an economic analysis shows that, due to an economy of scale, despite the capital cost reduction, microreactors are not cost competitive with large nuclear plants, but they are competitive with technologies with similar scale and application, such as diesel generators and renewable sources in microgrids.}, + keywords = {Microreactors,Nuclear energy,SMR}, + file = {/home/danesabo/Zotero/storage/MGZP6X8P/testoni2021.pdf;/home/danesabo/Zotero/storage/YLPCKPRW/Testoni et al. - 2021 - Review of nuclear microreactors Status, potentialities and challenges.pdf;/home/danesabo/Zotero/storage/HVDCW3NV/S0149197021001888.html} +} + @article{thalerProofsArgumentsZeroKnowledge, title = {Proofs, {{Arguments}}, and {{Zero-Knowledge}}}, author = {Thaler, Justin},
