Thermal and hydraulic analysis of a brazed aluminum evaporator
Applied Thermal Engineering, 2002Abstract This paper presents an analytical/computer model to predict the performance of a brazed aluminum evaporator operating under dehumidifying conditions. The evaporator uses small hydraulic diameter, flat multi-channel tubes and louver fins. The in-tube refrigerant flow was divided into three regions including the two-phase, liquid deficient and

Thermal-Hydraulic Analysis of the DEMO CS Coil
IEEE Transactions on Applied Superconductivity, 2018Two alternative designs of the central solenoid (CS) coil were proposed by EPFL-SPC PSI Villigen and CEA Cadarache for the European DEMO Tokamak. The DEMO CS coil consists of five modules, namely CSU3, CSU2, CS1, CSL2, and CSL3, the most demanding of which is the CS1.

Refined numerical modelling in thermal-hydraulic analysis
Nuclear Engineering and Design, 1990Abstract The paper presents the strategy for the development of numerical models and softwares in EDF and CEA, for the computation of nuclear reactor single-phase thermal-hydraulics problems. These tools use the Navier Stokes equations coupled with the k-lg3 model for turbulence, and have been validated upon simple situations of isothermal and ...

Treatment of the thermal–hydraulic uncertainties in the pressurized thermal shock analysis
Nuclear Engineering and Design, 2007Abstract The pressurized thermal shock (PTS) analysis is a quantitative analysis to calculate the vessel failure probability of the embrittled reactor pressure vessel. The PTS analysis consists of three major parts, such as the probabilistic safety analysis (PSA), the thermal–hydraulic analysis (T/H), and the probabilistic fracture mechanics (PFM ...

Thermal-hydraulic analysis of the TRADE spallation target
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2006The experimental facility TRADE serves to demonstrate the coupling between proton accelerator, spallation target and subcritical blanket at sizeable power (several 100 kW s). Solid tantalum target cooled with water is selected. The integrity of the spallation target has to be guaranteed during the entire operation time.

Thermal hydraulic transient analysis of the HTR-10
Nuclear Engineering and Design, 2002The HTR-10 is the first high temperature gas-cooled test module reactor built in China. In the accident analysis, typical design basis accident and beyond design basis accident (BDBA), including the reactivity accident, the loss of external power ATWS, the air ingress accident and water ingress accident into the primary system are selected and detailed

On the MEGAPIE Target Thermal Hydraulics: A RELAP5 Analysis
12th International Conference on Nuclear Engineering, Volume 2, 2004A new type of liquid-metal target is designed for the Spallation Neutron Source in PSI. LBE is selected to be the target material and the primary coolant as well. RELAP5/MOD 3.2 is used to analyze the system thermal hydraulics. The nominal conditions are chosen based on temperature constraints from the design assessments.

Thermal Hydraulic Analysis of a SCWR Core Concept
Volume 2: Plant Systems, Construction, Structures and Components; Next Generation Reactors and Advanced Reactors, 2013A Super Critical Water Reactor (SCWR) single channel analysis model was built considering energy coupling between water rods and coolant channels. By using this model, a comparative study was performed on SCWR fuel assembly arrangement such as the size and location of water rods and fuel pins.

Thermal Hydraulic Analysis of Severe Accident in PFBR
18th International Conference on Nuclear Engineering: Volume 4, Parts A and B, 2010During a core disruptive accident (CDA), the amount of primary sodium that can be released to Reactor Containment Building (RCB) in Prototype Fast Breeder Reactor (PFBR) is estimated to be 350 kg/s, by a transient fluid dynamic calculation. The pressure and temperature evolutions inside RCB, due to consequent sodium fire have been estimated by a ...
