The Modular Accident Analysis Program for CANDU (MAAP4-CANDU) was developed to assess the consequences of a severe core damage progression in a CANDU nuclear power station. The results from MAAP4-CANDU analyses support Level 2 PSA activities being performed for CANDU stations. During the early stages of a severe core damage accident in a CANDU plant, the primary heat transport system (PHTS) coo...

• Heat exchanger reactor prototypes are designed to study heat transfer in millimetric channels. coefficients zigzag channels 2 5 times higher than straight decreases when the channel cross section increases. A correlation is proposed for coefficient estimation performances of compact reactors were experimentally characterized and measurement uncertainties evaluated using derivation method. Pro...

Abstract The fuel shape and flow path structure of the plate-type reactor are different from those conventional rod-bundle reactor, which leads to difference between thermal-hydraulic phenomenon thermal conduction in rod bundle assembly. Therefore, this thesis, subchannel analysis model code applied developed. calculation results compared with simulation FLUENT MATRA experimental heat transfer ...

امروزه در مبحث محاسبات رآکتورهای هسته‌ای مثل فرسایش و مدیریت سوخت، تحلیل گذرا بازسازی توان میله‌های به دنبال روش‌هایی جهت استفاده کدهای هستند که علاوه بر دقت قابل‌قبول از هزینه زمان بهینه‌ای برخوردار باشند. این پژوهش با گسسته‌سازی معادله پخش نوترون روش نودال بسط شار جریان ‌متوسط مرتبه بالا نشان داده می‌شود روش‌ بهینه قابل‌قبولی بهره می‌برد. مستقیم الحاقی نوترون، برای هندسه مربعی دوبعدی دو گروه ...

Many studies have been conducted for quantitative/qualitative analysis and comparison of various teleoperation schemes. Position-position, force-position and 4-channels are to name a few. However most of this research has been focused on electrically actuated manipulators. This paper documents the comparative study of various teleoperation schemes explicitly for hydraulic manipulators. Identica...

We describe the use of immobilized enzymes in assay methods for the determination of glucose with glucose oxidase, uric acid with uricase, and urea with urease in serum samples. The enzyme reactor tubes were adapted to continuous-flow analyzers (Technicon AA II, SMA 12/60, and SMAC) used in routine laboratory determinations, and results with their use were compared to those from assays involvin...

This report presents the methods and calculated results of activity inventory in structural components Dalat Nuclear Research Reactor (DNRR). These include shielding concrete, reactor tank, its inside irradiated facilities; thermal thermalizing columns; horizontal channels. The MCNP5 code with a three-dimensional neutron transport model was used to calculate flux distribution, energy spectrum a...

Novel micro-structured string-reactor designed as catalytically active wires placed in parallel into a tube was developed. The small diameter of the channels (∼100 m) leads to a short radial diffusion time, a narrow residence time distribution (RTD), and a low pressure drop. This reactor was applied for the oxidative steam-reforming of methanol (OSRM) to produce hydrogen in autothermal mode for...
