Technological Perspectives for Propulsion on Nuclear Attack Submarines
World Journal of Nuclear Science and Technology, 2018Co-Authors: Luciano Ondir Freire, Delvonei Alves De AndradeAbstract:This work aimed at proposing a new combination of technologies to improve military performances and reduce costs of Nuclear Attack submarines, without overlooking safety constraints. The last generation of Nuclear Attack submarines increased size to meet safety and operational requirements, imposing huge burden on costs side, reducing fleet size. The limitations of current Technologies employed were qualitatively discussed, explaining their limitations. There are new technologies (plate and shell heat exchangers) and architectural choices, like passive safety, and segregation of safety and normal systems, which may lead to reduction of costs and size of submarines. A qualitative analysis was provided on this combination of technologies, stressing their commercial nature and maturity, which reduced risks. The qualitative analysis showed the strong and weak points of this proposal, which adopted the concept of strength in numbers. Concluding, new Technologies enabled the existence of 3800 t Nuclear Attack submarines with powerful propulsion systems and good acoustic discretion.

Fallout risk following a major Nuclear Attack on the United States.
Health physics, 1992Co-Authors: Ted F. Harvey, Charles S. Shapiro, Richard F. WittlerAbstract:Fallout distributions are calculated for Nuclear Attacks on the contiguous United States. Four Attack scenarios are treated, including counterforce and counterforce-countervalue Attacks, for meteorological conditions associated with a typical day in summer and one in winter. The countervalue Attacks contain mostly airbursts. To determine fallout effects, the population surviving the prompt effects is first calculated. For the prompt effects, a "conflagration-type" model is used. The counterforce Attack produces about 8 million prompt deaths, and the counterforce-countervalue case projects 98 million prompt deaths. Partial relocation before Attack to low-risk fallout areas at least 15 km from potential strategic targets would result in a decrease in projections of deaths by tens of millions. For fallout risk calculations, only the dose received in the first 48 h (the early or local fallout) is considered. Populations are assumed to be sheltered, with a shelter protection factor profile that varies for a large urban area, a small urban area, or a rural area. With these profiles, without relocation, the fallout fatalities for all four Attack scenarios are calculated to be less than one million people. This can be compared to fallout fatalities of about 10 million for a hypothetical unsheltered "phantom" population. Language: en

Russian choir draws criticism over performance describing Nuclear Attack on U.S.
2019Co-Authors: Louis CasianoAbstract:The Russian Orthodox Church expressed regret over a choir performance that featured a satirical Soviet-era song depicting a Nuclear Attack on the United States in the midst of heightened tension between Washington and Moscow.

After a Terrorist Nuclear Attack: Envisaging Catalytic Effects
Studies in Conflict & Terrorism, 2010Co-Authors: Robert AysonAbstract:It is just possible that a terrorist Nuclear Attack could catalyze an inter-state Nuclear war. The likelihood of a terrorist group gaining access to Nuclear weapons is lower than some fear, and terrorists might not use a Nuclear weapon as soon as they had acquired one. But if a terrorist group was to explode a Nuclear device in a country that was itself armed with Nuclear weapons, and especially if that country was in a conflict-prone relationship with another Nuclear-armed state, the broader consequences of even a single terrorist Nuclear detonation could be much more serious than some assume.
