Civil nuclear reactors are used for the production of electrical energy. In the nuclear industry vendors propose several nuclear reactor designs with a size from 35–45MWe up to 1600–1700MWe. The choice of the right design is a multidimensional problem since a utility has to include not only financial factors as levelised cost of electricity (LCOE) and internal rate of return (IRR), but also the...

This article demonstrates the feasibility of converting Iran’s 40MWt heavy-water research reactor at Arak (the IR-40) to use low-enriched uranium fuel in order to slow the production of weapon-usable plutonium. Two methods are proposed, and both retain identical power density, thermal-hydraulic, and safety profiles as the original design and require no physical alteration of the core. They can ...

the basic structure of a reactor physics laboratory environment simulation software, developed using object modeling technique (omt), and based on the reactor point kinetic equation, is presented. also, various capabilities of the simulator in teaching the fundamental concepts of reactor physics are discussed. in this virtual laboratory, student can perform seven different experiments, namely, ...

stable. The main results are: data normalization is fundamental to obtain better precision, the larger the number of data points, the lesser the error, the error decreases with the decreasing of noise level. The next step is to develop an Ipen nuclear research reactor model and apply the GMDH methodology to predict the reactor variables. This work is a part of a Monitoring and Diagnosis System ...

A highly enriched uranium coupled reactor consisting of pulse cores and a laser module is known as one of the reactors for nuclear-pumped laser. Neutronic analysis on a low enriched uranium coupled reactor which consists of pulse cores and a laser module was performed. Calculation results showed that a low enriched uranium coupled reactor could achieve criticality by using several expanded puls...
