We present a theoretical explanation for the intuitive proposition that the occupational safety conditions of on-site contract workers (employees of contracting firms) and employees (employees of host companies) are likely to differ. We derive ordinary imperfect information models from a review of regulations governing Japan’s nuclear utility industry. The models imply that hiring contract work...

We present in this paper a review of some recent work dedicated to the numerical interfacial coupling of fluid models. One main motivation of the whole work is to provide some meaningful methods and tools in order to compute unsteady patterns, while using distinct existing CFD codes in the nuclear industry. Thus, the main objective is to derive suitable boundary conditions for both codes to be ...

This paper describes the results of a research study sponsored by the UK nuclear industry into methods of justifying smart sensors. Smart sensors are increasingly being used in the nuclear industry; they have potential benefits such as greater accuracy and better noise filtering, and in many cases their analogue counterparts are no longer manufactured. However, smart sensors (as it is the case ...

John E. Hogan Georgia Institute of Technology School of Mechanical Engineering Atlanta. GA 30332 (404) 894-8165 A three-dimensional graphical environment, called the Multi-Body Simulator or MBSim, has been developed for the simulation, animation,' and control of multi-body mechanisms with or without sensors. The mechanisms can be composed of holonomic links. such as revolute and prismatic links...

The concept of organisational reliability is at the heart of the safety of at-risk systems. Many studies have been conducted in the nuclear industry; all emphasise the study of plants in normal, daily operation or during shutdowns. However, decommissioning, whether ongoing or planned, places a sharp focus on the question. This is because, on the one hand operating companies make significant cha...

The Writing Committee was selected to represent the American College of Cardiology (ACC) and the American Society of Nuclear Cardiology (ASNC) and included a cardiovascular training program director; a nuclear cardiology training program director; earlycareer experts; highly experienced specialists in both academic and community-based practice settings; and physicians experienced in defining an...

Today the applications of nuclear physics span a very broad range of topics and fields. This review discusses a number of aspects of these applications, including selected topics and concepts in nuclear reactor physics, nuclear fusion, nuclear non-proliferation, nuclear-geophysics, and nuclear medicine. The review begins with a historic summary of the early years in applied nuclear physics, wit...

Field Programmable Gate Arrays (FPGAs) have been gaining interest in the nuclear industry for a number of years. Their simplicity compared to microprocessor-based platforms is expected to simplify the licensing approach, and therefore reduce licensing project risks compared to software based solutions. However, few safety-related applications have been licensed in the nuclear industry; those th...

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...
