A nuclear liability framework for South Asia: formation of South Asia Association for Regional Cooperation (SAARC) nuclear risk community
South Asia is one of the densely populated regions of the world. A disaster in the nature of nuclear accident in one country will have a significant impact on the life and livelihood of large population across the region. Currently, major economies in South Asia are expanding their nuclear energy programmes, and this poses a transboundary risk. The risk is aggravated by the fact that countries in ...

Some aspects of producing regulations and guidelines for controlling safety in nuclear and radiation facilities
Because the regulation of nuclear and radiation safety is a national responsibility and in order to keep the use of nuclear energy for the welfare and prosperity of the nation and ensure that the use of nuclear energy is safe for man and the environment and does not promote the proliferation of nuclear weapons, an Atomic Energy Act and related legal regulations and decrees are a must for every ...

Limping legislation - viability of the Indian Nuclear Liability Act within the constitutional scheme
India's launch into the international nuclear regime has been controversial with allegations of being unconstitutional being levied on its liability legislation, the Civil Liability Act. This paper proposes to argue the legality of the legislation on the parameters of Constitutional mandates in fundamental rights of life, liberty and equality. On dissection, it finds the legislation in breach of ...

Prospects of nuclear desalination and highlights of related IAEA activities
Currently, several IAEA Member States have shown interest in using nuclear energy for seawater desalination, not only because recent studies have demonstrated that nuclear desalination is feasible, but also because it is economical and has already been demonstrated in several countries. Therefore, this paper will provide a highlight on seawater desalination using nuclear energy as a potential for ...

Risk management in a scientific research nuclear installation decommissioning project
With the development of nuclear technology and engineering, more and more scientific research nuclear installations have already or will enter the phase of decommissioning. Based on the risk management of a nuclear installation decommissioning project, this paper analyses the risk factors and their effects, then puts forward relative measures and suggestions.Keywords: nuclear decommissioning, ...

Experimental determination of dose uniformity in the CDTN gamma irradiator
This paper describes an experimental study of dose uniformity within a container used for products irradiation, in the gamma irradiation facility at Nuclear Technology Development Center (CDTN). The CDTN is a research institute of the National Nuclear Energy Commission (CNEN), Brazil. Polymethylmethacrylate (PMMA) dosimeters were used in order to determine the Dose Uniformity Ratio (DUR) inside ...

Media reporting and changes in public opinion after Fukushima nuclear accident: Belgium as case study
This study examines the Belgian press coverage related to the Fukushima nuclear accident and investigates the changes in the public opinion related to nuclear energy. Two research methodologies were applied. The first method conducted was a content analysis of two quality newspapers in Belgium, covering the first two months after the accident. The second method was a public opinion survey, based ...

Nuclear technology and its challenges in India
India has a strong technology base for its comprehensive nuclear energy programme. A glimpse of this capability is given in this paper, starting with uranium exploration and mining to fuel reprocessing and nuclear waste management. India has chosen a closed fuel cycle option, and the plutonium recovered from spent fuel will soon be manufactured into fuel elements for its 500 MWe Prototype Fast ...

Condensed matter nuclear science (cold fusion): an update
Seventeen years after the announcement by Professors Stanley Pons and Martin Fleischmann of the discovery of cold fusion in March 1989, the scientific community does not acknowledge this field as a genuine scientific research theme. However, the scientific demonstration of cold fusion was made long ago by showing the evidence of excess heat production in electrolytic cells and other devices. ...

Vietnam: ensuring safety and security for peaceful uses of atomic energy
Atomic energy applications have been developed and used in various sectors of the national economy in Vietnam. Recently, the Government has approved the 'Strategy for Peaceful Uses of Atomic Energy up to 2020'. The government has also acknowledged that to ensure safety and security for the development of atomic energy applications, it is especially essential to strengthen the state management in ...

An IAEA survey on the current status of knowledge preservation in nuclear and supporting organisations
Knowledge Preservation (KP) is part of the larger process of knowledge management and a variety of methods and tools are used to capture, process, organise, store, retrieve, exchange and communicate nuclear knowledge. A benchmark survey was conducted to determine the current and anticipated status of nuclear KP in International Atomic Energy Agency (IAEA) member states. This article presents an ...

The cost benefit of a light water reactor safety study in JAERI
A cost benefit effect of nuclear energy is studied in this paper, where the reduction of Nuclear Accident Compensation Insurance (NACI) by reducing the accident risk of LWR and the contribution of the JAEA LWR safety study to NACI are main parameters. It is revealed that the reduced amounts by NACI was 240 million dollars (M$), omitting the contributions from research reactors. This value is ...

Decision support for the management of aging nuclear critical infrastructures: vulnerability assessment and multi-criteria decision analysis
Because many nuclear facilities are nearing the end of their design life, it is important to assess the vulnerability of these aging critical infrastructure systems. The risks associated with nuclear energy are often complex and uncertain, including the release of radioactive fission and environmental issues related to the longevity and toxicity of waste products. In the event of a nuclear ...

Thermodynamic limitations to nuclear energy deployment as a greenhouse gas mitigation technology
To both replace fossil-fuel-energy use and meet the future energy demands, nuclear energy production would have to increase by 10.5% per year from 2010 to 2050. This large growth rate creates a cannibalistic effect, where nuclear energy must be used to supply the energy for future nuclear power plants. This study showed that the limit of ore grade to offset greenhouse gas emissions is ...

Spent nuclear fuel and the principle of national responsibility: national policies in a European context; the case of Sweden
The principle of national responsibility is of essential importance for the international regulation of nuclear waste and spent nuclear fuel. The principle lays down the obligation of each state producing nuclear energy to take responsibility for the residual products that this production generates. It is a principle that can be, and has been, invoked on a national level to provide a legal basis ...

Looking through the prism of international environment and human rights law - International Civil Nuclear Liability Law and a call for Indian exceptionalism
As the spectre of climate change and competition over fossil fuels have led energy–hungry states towards nuclear power, liability rules for nuclear damage have acquired increased significance. However, many of the core common elements of the existing international legal regimes on civil nuclear liability - channelling of liability, quantum and temporal limits, definition of harm, etc. - are not ...

Sovereignty of states, peaceful nuclear energy and principles of international environmental law
The sovereign right of states to peaceful nuclear energy is analysed on the basis of principles of international environmental law. The exercise of this right depends on the implementation of certain obligations under international law. The notion of sovereignty as independence and superiority does not serve the challenges of peaceful nuclear energy and the modern understanding of the environment ...

Fuzzy finite element analysis of multi–group neutron diffusion equation with imprecise parameters
In this paper, multi–group neutron diffusion equation with imprecise parameters has been solved using proposed fuzzy finite element method. The proposed method is demonstrated by investigating the neutron fluxes viz. thermal and fast group fluxes of a benchmark problem ANL–BSS–6–A2. Various parameters such as thermal conductivity, diffusion, group fission and neutron interaction constants are ...
