After the first concrete was poured on December 9, 2012 at Shidao Bay site in Rongcheng, Shandong Province, China, construction of reactor building for world's high-temperature gas-cooled pebble-bed module (HTR-PM) demonstration power plant completed June, 2015. Installation main equipment then began, and is currently progressing well toward connecting to grid end 2017. The thermal a single HTR-PM 250 MWth, helium temperatures core inlet/outlet are 250/750 °C, steam 13.25 MPa/567 °C produced...
The Breit-Wheeler process which produces matter and anti-matter from photon collisions is investigated experimentally through the observation of 6085 exclusive electron-positron pairs in ultra-peripheral Au+Au at $\sqrt{s_{_{NN}}}=200$ GeV. measurements reveal a large fourth-order angular modulation $\cos{4\Delta\phi}=(16.8\pm2.5)\%$ smooth invariant mass distribution absent vector mesons ($\phi$, $\omega$ $\rho$) experimental limit $\le 0.2\%$ observed yields. differential cross section as...
Nuclear plant modeling and control is an important subject in nuclear power engineering, giving the dynamic model from process mechanics and/or operational data as well guaranteeing satisfactory transient steady-state performance by well-designed laws. With fast development of small modular reactors (SMRs) context massive integration intermittent renewables, it required to operate plants more reliably, efficiently, flexibly smartly, motivating recent exciting progress control. In this paper,...
Small modular reactors are the nuclear fission with electric power output less than 300 MWe. To apply enhanced safety of small to build large-scale plants any desired ratings, multi-modular scheme is recommended be adopted, where multiple reactor modules utilized drive common load equipment for generation or cogeneration. The feasibility not verified until several plant-wide tests were carried out recently on high temperature gas-cooled pebble-bed module (HTR-PM) plant. HTR-PM plant consists...
U-tube steam generator (UTSG) is one of the most important facilities in a pressurized-water nuclear reactor. The water level control UTSG crucial to secure sufficient cooling inventory for reactor and, at same time, prevent damage turbine blades. Because high nonlinearity and nonminimum phase characteristics dynamics, it necessary establish an effective nonlinear water-level controller. After establishing state-space model UTSG, output feedback dissipation (OFDC) systems presented, then...
Based on the multi-modular scheme, modular high temperature gas-cooled reactor (MHTGR) can be used to build large-scale nuclear power plants with inherent safety feature at any desired ratings. It is so clear that module coordinated control very crucial for safe and stable operation of MHTGR plants, which induces importance study in coordination. Motivated by this, it revealed this paper multiple MHTGR-based NSSS modules essentially flowrate-pressure regulation a fluid flow network (FFN). A...
Nuclear fission reaction provides more and energy required for generating electrical power in the world, therefore load-following control has become an important technique nuclear reactor regulation. A novel nonlinear controller called observer-based feedback dissipation single-output-single-input (SISO) generalized Hamiltonian systems is presented this paper. The observer a dissipative structure, sufficient condition closed-loop asymptotical stability also derived. This strategy then...
Because of the inherent safety feature, modular high temperature gas-cooled reactor (MHTGR) has been seen as one best candidates for next generation nuclear power plants. Power-regulation is a key technique to provide safe, stable and efficient plant operation multi-reactor-module Based on successful design Chinese test HTR-10, gas cooled pebble-bed module (HTR-PM) project proposed. Since HTR-PM composed two interconnected steam supply system (NSSS), strategy multi-reactor-modular different...
Reactivity is a key physical parameter that directly reflects the balance between neutron generation and consumption in every nuclear fission reactor. In this paper, by regarding reactivity as an extended state-variable of point kinetics, novel state-observer (ESO) proposed. Theoretic analysis shows newly-built ESO provides globally asymptotically bounded estimation for reactor flux, concentrations delayed precursors reactivity. Numerical simulation results illustrate influence observer to...
Growing electricity requirement and the serious pollution caused by burning petroleum coal give current rebirth of nuclear energy industry. State observation is one key basic technologies system monitoring which very necessary to safe effective operation today's reactors. Since reactors are complex nonlinear systems, it quite design a state-observer with high-performance for A dissipation-based high gain filter (DHGF) presented systems in this paper, robustness analysis also given. The DHGF...
