Failure Assessment Diagram in Structural Integrity Analysis of Steam Generator Tubes
(Elsevier Science, 2015-07-02)
The assessment of the structural integrity of Steam Generator Tubes (SGTs) in nuclear power plants has been receiving increasing attention in the literature in the last years due to the negative impact related to their ...
Numerical study of the applicability of the η-factor method to J-resistance curve determination of steam generator tubes using non-standard specimens
(Pergamon-Elsevier Science Ltd, 2015-09)
The suitability of the η-factor method for the determination of J-resistance curves of thin walled steam generator tubes was evaluated using elastoplastic finite element analysis. Different candidate non-standard specimens' ...
Structural integrity assessments of steam generator tubes using the FAD methodology
(Elsevier Science Sa, 2015-12)
Steam generator tubes (SGTs) represents up to 60% of the total primary pressure retaining boundary area of a nuclear power plant. They have been found susceptible to diverse degradation mechanisms during service. Due to ...
Bio-ethanol steam reforming and autothermal reforming in 3-μm channels coated with RhPd/CeO2 for hydrogen generation
(Elsevier Science, 2013-02)
A silicon micromonolith of 7 mm diameter and 0.2 mm length containing 1.5 million regular channels with a diameter of 3.3 μm was used for obtaining hydrogen through ethanol or bio-ethanol steam reforming (ESR) and oxidative ...

Thermodynamic analysis of direct steam reforming of ethanol in molten carbonate fuel cell
(Asme-amer Soc Mechanical Eng, 2014)
Microgeração de energia elétrica (Abaixo de 100 kW) utilizando turbina Tesla modificada
An economical electricity generating system is developed, i.e., a boiler and turbine with a capacity ≤ 100 kw, to occupy a niche market where the existing steam systems are not economically viable. A Tesla turbine is used. ...
Thermodynamic analysis of the cogeneration system expansion in a sugar-alcohol factory
(Natl Technical Univ Athens, 2006-01-01)
In this work it was performed energetic and exergetic analyses of three thermal plants to assessment a cogeneration system in expansion of a sugar-alcohol factory. The initial configuration considered is constituted by a ...
