  • Common sense considerations on nuclear safety today

    Several recent astonishing events at nuclear plants are recalled in this paper. These events are of the type of ‘possible but not credible’ events. The Fukushima tsunami (2011) is the most recent and catastrophic one. A discussion is made on the present (very conservative) safety philosophy and on the reasons why, notwithstanding it, catastrophe (uncontained core melts) may happen at nuclear ...

  • Water monitoring as a safety feature for nuclear desalination

    It is widely accepted that the general safety approach for nuclear facilities is valid for a Nuclear Desalination Plant (NDP), thus IAEA standards and guides are applicable. The coupling of a NDP should be designed with the safety objective of ensuring that it results in no adverse effect on the Nuclear Power Plant (NPP) safety. The first objective (provisions of barriers) is complied with by the ...

  • Fault-tolerant power supply for safety significant nuclear instrumentation and control

    Nuclear Instrumentation and Control (I&C) must address the issue of power supply differently from other commercial control systems. What is doable for commercial plants, such as a thermal power station, should not be applied for Nuclear Power Plant I&C. The hazards arising from power supply failure in nuclear power stations cannot be compared with other commercial systems. Therefore, the use of ...

  • Failure possibilities for nuclear safety assessment by fault tree analysis

    Fault tree analysis (FTA) is a deductive tool to assess the safety of nuclear power plants. This analysis can only be implemented if all basic events in the tree have their corresponding failure rates. Therefore, safety analysts have to provide those failure rates well in advance. However, it is often difficult to obtain those failure rates due to insufficient data, changing environment or new ...

  • Prospects of nuclear desalination in Morocco

    In the last few years, Morocco has faced a continuous series of dry seasons, which has put a great stress on its limited water resources. Hence, for some time now Morocco has been considering desalinating seawater to supply fresh water to some areas. In the early 1980's, due to limited energy resources, Morocco was obliged to consider other alternatives to meet its energy demands. A feasibility ...

  • Value addition in diamonds and other gemstones by nuclear radiation: the phobias and safety considerations

    Four Cs, namely colour, clarity, carat (weight) and cut, primarily determine the price of a gem. Neutron irradiation, gamma rays and electron beams can be used to enhance the colour and clarity of aquamarine, quartz, tourmaline, kunzite, topaz, pearls and, most importantly, diamonds. Imparting colour and clarity to these gems that are otherwise devoid of these attributes results in significant ...

  • Safety and productivity trade-offs: managing nuclear reactor outages

    Risk management is a critical function in all organisations, particularly those that operate high-risk systems such as chemical processing facilities or offshore oil platforms. In this context, risk management extends beyond the protection of financial assets to deal with issues of public concern including human safety and environmental impact. It is clear that these critical systems operate with ...

  • Winners, Losers, and the Nuclear-Waste Dilemma

    This paper explores how property-right assignment affects social efficiency when a public program has both “public good” and “public bad” components. We show that when willingness to accept a public bad exceeds the willingness to pay, the net benefit is unambiguously lower when the property right supports the status quo institutional structure. Thus, Kaldor–Hicks efficiency tests tend to favor ...
