“…The design has several features that differentiate it from other existing containment systems. First, the rated pressure is 5.5 MPa (800 psia), which is 12 times higher than old-style containments [1]. As a result, the design is claimed can withstand all LOCAs that may occur inside containment.…”

“…The module comprises of 160 MWt reactor core and other primary system components that are housed in single reactor pressure vessel and enclosed by a relatively small steel containment vessel, which is submerged in a large pool of water. Several power modules (as many as 12 modules) can be co-placed in the same pool [1].…”

NUMERICAL STUDY ON CONDENSATION IN IMMERSED CONTAINMENT SYSTEM OF ADVANCED SMR DURING UNCONTROLLED DEPRESSURIZATION.A number of Small Modular Reactor designs have been developed by several countries and mostly each comes with specific innovative improvements. One of them is NuScale reactor which implements a steel, small size immersed-in-pool containment system. This new approach derives new challenges as control for temperature and pressure inside the containment is conducted without any active system. Passive heat transfer and condensation is important parameter that needs to be investigated for this kind of containment design. Hence, this work examines the condensation, pressure and the effect of pool temperature on capability of the containment to remove heat and maintain integrity passively. The work is performed using numerical simulation by modeling the reactor in RELAP5 code. Calculation result shows that during depressurization, maximum pressure limit of 5.5 MPa is not exceeded. Besides, the containment design provides enough capability to transfer heat from the containment to water pool passively. This work also investigates sensitivity analysis of pool temperature which shows that for an increase of about 17 o C, heat removal from the containment to water pool is only slightly affected with value less than 3 percent.Keywords: Containment, Condensation, RELAP5, NuScale, Depressurization ABSTRAK STUDI NUMERIK PROSES KONDENSASI PADA SISTEM PENGUNGKUNG TERENDAM UNTUK SMR SAAT DEPRESURISASI TAK TERKENDALI.

“…Licensing small modular light water reactors with new features, such as passive cooling, is challenging and in most countries associated with increased costs for the licensing procedure and uncertainties regarding the outcome of the licensing process [119,120]. NuScale's present attempts to license their small modular reactor design in the U.S. may be a good example of this [121,122]. Licensing small modular reactors that are not only different in power level but show fundamental differences to currently deployed light water reactors such as a different coolant or moderator creates additional uncertainties for the licensor and thus increase the risk of the applicant to provide additional information, that results in increased costs for the overall licensing procedure [123][124][125][126][127][128].…”

On the Sustainability and Progress of Energy Neutral Mineral Processing

et al. 2018

A number of primary ores such as phosphate rock, gold-, copper-and rare earth ores contain considerable amounts of accompanying uranium and other critical materials. Energy neutral mineral processing is the extraction of unconventional uranium during primary ore processing to use it, after enrichment and fuel production, to generate greenhouse gas lean energy in a nuclear reactor. Energy neutrality is reached if the energy produced from the extracted uranium is equal to or larger than the energy required for primary ore processing, uranium extraction, -conversion, -enrichment and -fuel production. This work discusses the sustainability of energy neutral mineral processing and provides an overview of the current progress of a multinational research project on that topic conducted under the umbrella of the International Atomic Energy Agency.

“…The secondary coolant is injected to the secondary side of the OTSGs or OTHXs and is changed to be the satisfactory working fluid for driving different thermal loads such as a steam turbine. Actually, OTHSS are very common in practical engineering such as the integral pressurized water reactors (iPWR, e.g., Nuscale, IRIS and mPower) with internal OTSGs [3][4][5][6], modular high temperature gas-cooled reactor (MHTGR, e.g., HTR-Module [7][8][9], MHTGR [10] and HTR-PM [11][12][13]) with side-by-side arranged OTSGs, concentrating solar power (CSP) plants with OTSGs [14] or OTHXs [15] and even coal-fired once-through boilers. A thermally interconnected distributed energy system is called a hybrid energy system (HES) [16][17][18] if the heat sources of OTHSS modules are of different types, otherwise it is called a multimodular energy system.…”

Modeling and Control of Fluid Flow Networks with Application to a Nuclear-Solar Hybrid Plant

et al. 2017

Fluid flow networks (FFNs) can be utilized to integrate multiple once-through heat supply system (OTHSS) modules based on either the same or different energy resources such as the renewable, nuclear and fossil for multi-modular and hybrid energy systems. Modeling and control is very important for the safe, stable and efficient operation of the FFNs, whose objective is to maintain both the flowrates and pressure-drops of the network branches within specific bounds. In this paper, a differential-algebraic nonlinear dynamic model for general FFNs with multiple pump branches is proposed based on both the branch hydraulics and network graph properties. Then, an adaptive decentralized FFN flowrate-pressure control law, which takes a proportional-integral (PI) form with saturation on the integral terms, is established. This newly-built control not only guarantees satisfactory closed-loop global stability but also has no need for the values of network hydraulic parameters. This adaptive control is then applied to the flowrate-pressure regulation of the secondary FFN of a two-modular nuclear-solar hybrid energy system and numerical simulation results show the feasibility and high performance of this network control strategy. Due to its concise form, this new flowrate-pressure FFN controller can be easily implemented practically.
