Development of a Gas-Cooled, Large-Capacity, Gas-Insulated Shunt Reactor

Large Eddy Simulation in Pebble Bed Gas Cooled Core Reactors

A High Temperature Gas-cooled Reactor (HTGR) is one of the renewed reactor designs to play a role in nuclear power generation. This reactor design concept is currently under consideration and development worldwide. The combination of coated particle fuel, inert helium gas as coolant and graphite moderated reactor makes possible to operate at high temperature yielding a high efficiency. In this ...

hazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures

شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...

Adaptive Polynomial Chaos Techniques for Uncertainty Quantification of a Gas Cooled Fast Reactor Transient

Uncertainty quantification plays an increasingly important role in the nuclear community, especially with the rise of Best Estimate Plus Uncertainty methodologies. Sensitivity analysis, surrogate models, Monte Carlo sampling and several other techniques can be used to propagate input uncertainties. In recent years however polynomial chaos expansion has become a popular alternative providing hig...

Detection in Spacer of Gas-Insulated Switchgears

With the increasing demand for precise condition monitoring and diagnosis of 11 gas-insulated switchgears (GIS), it has become a challenge to improve the detection sensitivity of 12 partial discharge (PD) induced in the GIS spacer. This paper deals with the elimination of the 13 capacitive component from the phase resolved partial discharge (PRPD) signal generated in GIS 14 spacer based on the ...
