Throughout the world, and especially in the European Union, numerous technologies for the thermal treatment of radioactive waste are available or being developed. These technologies can be applied to a large range of different radioactive waste streams, including non-standard types of waste that present specific waste management challenges. Thermal treatment can result in a significant reduction in volume and hazard, which are beneficial for safe storage and disposal. Thermal treatment also removes organic material that can form complexing agents and increase the mobility of radionuclides in the landfill. In the paper, basic thermal techniques are presented, and some examples of the installations are shown. Common knowledge of these methods may result in an increased public acceptance of nuclear energy in a country just introducing it, as Poland is.

Abstract It is a striking and happy reality today at the same time, marked universally: What it is agreed to call the nuclear controversy is remained circumscribed with nuclear energy and rather confined with the industrialized countries. The other economic and social applications of the nuclear techniques experience a very important development all over the world and which has to continue. The countries of intermediate socio-economic level do not escape this report. And even if these countries have, generally, slightly resorted to nuclear energy, the World Energy Conference (the USA, 1999) provides that nuclear energy will know in the court - medium term a rise in the emerging countries which will come to compensate for its relative retreat in the industrialized countries. There is consequently a number unceasingly crescent of “small producers” of radioactive waste particularly in the emerging countries but, unfortunately, this waste is not dealt with in a rigorous and exhaustive way, generating a potential serious threat engraves for the people and the environment. The analysis of this situation, from the case of Tunisia, reveals the following cause: miss of infrastructures, qualified personnel, financial means and impossibility of coping with these difficulties without international co-operation there. In this communication we propose a strategy, on a 20 years horizon of management of the radioactive waste for Tunisia taking account of the means of the country and the essential contribution of the co-operation. We make share in this respect already committed experiment of the three-way co-operation Tunisia - IAEA - Belgium. The strategy that we propose articulates on the following points: 1. Definition of the long-term objectives and the principles; 2. The institutional and regular project; 3. The inventory of the radioactive waste; 4. The planning of the formation; 5. The project of a pilot unit for waste processing and storage; 6. The question of the evacuation; The above actions are evoked in interference with the role of the international co-operation.

Safe management of radioactive waste is challenging to waste producers and waste management organisations. Deployment of thermal treatment technologies can provide significant improvements: volume reduction, waste passivation, organics destruction, safety demonstration facilitation, etc. The EC-funded THERAMIN project enables an EU-wide strategic review and assessment of the value of thermal treatment technologies applicable to Low and Intermediate Level waste streams (ion exchange media, soft operational waste, sludges, organic waste, and liquids). THERAMIN compiles an EU-wide database of wastes, which could be treated by thermal technologies and documents available thermal technologies. Applicability and benefits of technologies to the identified waste streams will be evaluated through full-scale demonstration tests by project partners. Safety case implications will also be assessed through the study of the disposability of thermally treated waste products. This paper will communicate the strategic aims of the ongoing project and highlight some key findings and results achieved to date.

The article analyses critera applying to the choice of energy efficient high quality light sources and luminaires, which are used in Russian domestic and international practice. It is found that national standards GOST P 54993–2012 and GOST P 54992– 2012 contain outdated criteria for determining indices and classes of energy efficiency of light sources and luminaires. They are taken from the 1998 EU Directive #98/11/EU “Electric lamps”, in which LED light sources and discharge lamps of high intensity were not included. A new Regulation of the European Union #874/2012/EU on energy labelling of electric lamps and luminaires, in which these light sources are taken into consideration, contains a new technique of determining classes of energy efficiency and new, higher classes are added. The article has carried out a comparison of calculations of the energy efficiency classes in accordance with GOST P 54993 and with Regulation #874/2012/EU, and it is found out that a calculation using GOST P 54993 gives underrated energy efficiency classes. This can lead to interdiction of export for certain light sources and luminaires, can discredit Russian domestic manufacturer light sources and does not correspond to the rules of the World Trade Organization (WTO).

Authors from the Christian Right in the USA situate the September 11 attack on New York and Washington within God's intentions to bring America into the divine schedule for the end of the world. This is true of Pat Robertson and Jerry Falwell, and other leading figures in the ‘Christian Coalition’. This article analyses how Christian fundamentalists assess the roles of the USA, the State of Israel, Islam, Iraq, the European Union and Russia within what they perceive to be the divine plan for the future of the world, especially against the background of ‘9/11’. It argues that the ideas of the Christian Right and of President George W. Bush coalesce to a high degree. Whereas before 9/11 many American mega-church preachers had aspirations to direct political life, after the events of that day the President assumes some of the roles of a mega-religious leader.

This paper aims to explore Pakistan's geo-economic options in the difficult situation that confronts following the easing of sanctions, which added acute balance of payments pressures to its existing ailments of near-stagnant exports, a lower growth trend than in preceding decades, an unattractive climate for foreign investment, and weak social indicators. The first question explored is whether Pakistan has any opportunity of participating in a regional trade grouping. It is argued that the only conceivable way of achieving this would involve the development of SAARC, which would demand a profound transformation of Indo-Pakistani relations (though one no more profound than that realised in Franco-German relations since the founding of what is now known as the European Union). One benefit of achieving deep integration through SAARC is that this would create the possibility of Pakistan developing a serious engineering industry far more rapidly than will otherwise happen. In the absence of deep integration in SAARC, it is argued that Pakistan's best option would be a policy close to unilateral free trade, so as to place it in a position to take advantage of whatever the next generation of labour-intensive activities demanded by the world economy proves to be. Under either of those scenarios, the reestablishment of a dynamic industrial sector will require the maintenance of a competitive exchange rate, something that, it is argued, is not necessarily guaranteed by floating. The paper also discusses the role of inward direct investment in contributing to the export success of East Asia, and considers whether the expatriate Pakistani community might be capable of playing a role comparable to that played by the overseas Chinese in nurturing the Chinese export expansion of the last two decades. It is suggested that such a hope was set back by the extra-legal attempt to renegotiate power tariffs with the independent power producers in the course of 1998, and that Pakistan needs to become a country of laws rather than discretion if foreign investors, including expatriate Pakistanis, are ever to find the country an attractive export platform. While more inward direct investment would almost certainly be beneficial, the same is not true for inward financial investment, where too large an inflow can easily expose a country to very significant risks, as the East Asian crisis showed. In the long run, Pakistan needs to be prepared to repel excessive capital inflows if they materialise; but its immediate problem is still balance of payments pressure, and this seems to demand targeting a major and sustained improvement in the current account over the next several years.
