PARAMETRIC STUDY OF THE STRUCTURAL RESPONSE OF NPP CONTAINMENT TO IMPACT LOADING

Abstract

The presented article is a contribution to the discussion concerning nuclear safety which has intensified after the Fukushima Daiichi nuclear disaster. A parametric study concerning various materials, containment wall thicknesses and different aircraft speeds at the time of impact was performed. The aim of this study was to establish damage extent of various variants of a containment structure. Containment damage was evaluated by means of the value of maximum permanent deformation and plastic strain extent. The purpose of this study was also to foster experiential suggestions for improving the explicit method in the RFEM program in order to release it for RFEM users.

Nuclear Smuggling and Threats to Lithuanian Security

Abstract

The article explores threats related to illicit trafficking of radioactive materials and dual-use goods applicable in state level nuclear programs, actualizing the global trends for the Baltic region. The article points to Eastern Europe’s changing risk profile in this respect, as increasing penetration of Russian criminal groups inside Ukraine and the destabilized situations in neighboring countries create an environment where the risk of nuclear smuggling is on the rise. Criminal entities can be seen forming new bonds, with trafficking routes intersecting and zones of influence shifting - consequently, an unusual level of criminal involvement in nuclear smuggling is observed, alongside a geographic shift of smuggling patterns. In addition, states seeking materials and technologies for their military programs have taken a notable interest in this region as a way of circumventing international transit regulations. The article looks at the likely implications of these new nuclear smuggling trends for the security of the Baltic states. It suggests that Lithuania may soon be facing a relatively new threat, and one that it is ill-prepared to counter. The article discusses the risk factors and indicators to watch before that risk becomes reality, and offers ways for Lithuania to contribute to addressing these increasingly acute problems on a regional level.

The Impact of the US Military Transformation on North Korean Defence Policy

Abstract

This article presents an interpretation of the US capacity to force North Korea to abandon the development of nuclear weapons, based on the analysis of the conventional balance between the U.S. and North Korea. It is also an attempt to evaluate the impact of the US military transformation on defence policy decisions of the potential opponents of the US. The first (theoretical) part of the article presents the assumptions of theoretical interpretation as well as the fundamentals of evaluating the conventional balance between the US and North Korea. The second part of the article highlights the key moments of the US and the international community’s so far unsuccessful attempts to force North Korea to give up its nuclear weapons and explains the reasons for such unsuccessful policy. The third part of this paper analyzes the conventional balance between the US and North Korea, taking into account the conventional forces of those countries, their long range conventional strike programmes as well as the missile defence programmss - this analysis presupposes the failure of the US to prevent North Korea from nuclear weapon development

Application of instruments of nuclear physics to the calculation of theoretical dose distributions in various organs of the human body for beams used in hadrontherapy

Abstract

The area of interests of nuclear physics are studies of reactions, wherein atomic nuclei of projectile collide with target nuclei. An amount of energy lost by projectile nucleus during its passing through the target is a major issue – it is important to know how charged particles interact with matter. It is possible to afford this knowledge by using theoretical programs that calculate energy loss applying the Bethe-Bloch equation. Hadrontherapy, which is a field of still growing interest, is based on the interactions of charged particles with matter. Therefore, there exists a need of creating a simple model that could be used to the calculation of dose distributions in biological matter. Two programs (SRIM, Xeloss), used to the calculation of energy loss by nuclear physicist, have been adapted to determine the dose distributions in analogues of human tissues. Results of the calculations with those programs for beams used in hadrontherapy (e.g. 1H, 12C) will be compared with experimental data available in references.
