In risk analysis, the treatment of the epistemic uncertainty associated to the probability of occurrence of an event is fundamental. Traditionally, probabilistic distributions have been used to characterize the epistemic uncertainty due to imprecise knowledge of the parameters in risk models. On the other hand, it has been argued that in certain instances such uncertainty may be best accounted ...

This text presents a block diagram proposal of protection system for a PWR nuclear power plant. It describes the plant operation, as well as it defines what a protection system is. Some of the main inherent definitions to protection systems are shown and the system operation is explained in a global form. The block diagram proposed for the protection system can be used as a project foundation f...

On March 11, 2011, Japan was consecutively hit by three unprecedented disasters caused by The Great East Japan (Tohoku) Earthquake: an earthquake of magnitude 9.0, an incredibly powerful tsunami, and a nuclear power plant breakdown. As Japan had experienced The Great HanshinAwaji Earthquake in 1995, we were prepared to provide the victims with appropriate medical care to some extent. Neverthele...

The Prime Power Conjecture (PPC) states that abelian planar difference sets of order n exist only for n a prime power. Evans and Mann [1] verified this for cyclic difference sets for n ≤ 1600. In this paper we use the Mann test to verify the PPC for n ≤ 2, 000, 000.

The majority of our citizens are aware of the contributions of nuclear technology to the production of electricity via commercial nuclear power plants. But most are unaware that the impact of this technology is even greater for non-power applications. The world of medicine, agriculture, and modern industry has been substantially improved by the harnessing of radioisotopes, and new applications ...

Field profiles, equivalent isotropic radiated power (EIRP), beamwidth, and sidelobe levels of a quasi-optical powercombining grid amplifier structure are obtained using a wholefield electromagnetic analysis of a finite structure. This is efficiently obtained using a mixed spectraland spatial-domain method-of-moments technique. It is seen that edge effects can have a significant effect on system...

The objective of this study was to examine childhood cancer incidence in proximity to nuclear power plants in Illinois. Cancer cases diagnosed among Illinois children 0 to 14 years old from 1986 through 2005 were included in the study. Standardized incidence ratio (SIR) was calculated for the geographic zones defined by the proximity to nuclear power plants. The results show that children livin...
