The applicability of employing a parameter-dependent control to a nuclear pressurized water reactor is investigated and is compared to that of using an H1 control. A linear time-invariant controller cannot maintain performance over the entire operating range. The parameterdependent synthesis technique produces a controller which achieves speci ed performance against the worst-case time variatio...

The purpose of this paper is to present an approach to optimization in which every target is considered as a separate objective to be optimized. For an efficient search through the solution space we use a multiobjective genetic algorithm which allows us to identify a set of Pareto optimal solutions providing the decision maker with the complete spectrum of optimal solutions with respect to the ...

Abstract Corrosion products in the primary circuit of Pressurized Water Reactor (PWR) during operation will cause Chalk Rivers Unidentified Deposit (CRUD), increase level coolant source term and deposition outside core, then affect normal PWR radiation field shutdown overhaul. Stretch-Out (SO) is a flexible mode reactor, which can improve economy reactor. In this paper, theoretical model CRUD a...

The noninvasive investigation of flows, where media of different optical density participate, is often not possible. A measurement through dynamic water-air surfaces will result in higher measurement uncertainties or they will hinder any measurement at all. To overcome this issue we make use of adaptive optics (AO). Dependent on the measurement system, an adaptive correction of the illumination...

SUMMARY Poor control of steam generator water level of a nuclear power plant may lead to frequent nuclear reactor shutdowns. These shutdowns are more common at low power where the plant exhibits strong non-minimum p...

have sprung to life in these recent years at the welcome sight of a possible nuclear power renaissance, IRIS (International Reactor Innovative and Secure) is the one that has moved most rapidly from an idea to a viable, albeit still at the preliminary design stage, commercial entry. IRIS is a modular pressurized water reactor with an integral configuration (all primary system components—pumps, ...

Due to limited sources of natural uranium, Department of Atomic Energy (DAE) has sought thorium (Th) as an alternative source of nuclear fuel. India has one of the largest deposits of natural Th in the form of monazite in Kerala. The currently known Indian Th reserves amount to 155,000 GWe-yr of electrical energy and can meet the energy requirements during the next century and beyond. Thorium-2...
