Safety at a nuclear power plant is essential, and safety standards are constantly reviewed and upgraded as new developments and research are performed. Constant research regarding this subject is fundamental for the nuclear industry.

Although severe accident analysis and research has been performed throughout the evolution of nuclear industry, it has not yet considered all plausible scenarios. Adequate analyses are needed for all phases of this matter in order to maintain or improve safety margins. Hence it is essential to encourage researchers to keep performing and developing research, codes, and simulations of these potentially dangerous events.

This is why we invite researchers to contribute with original works in an effort to improve nuclear safety and severe accident guidelines. We are interested in articles which can help improve safety in existing generation II nuclear power plants (NPP) as well as in generation III NPP being built and in generation III+ and IV NPP being developed. Potential topics include, but are not limited to:

• Core chemical reactions and behavior
• Core heat-up, degradation or damage, decay heat removal, and postaccident heat removal
• Cool-ability of severely damaged core in the reactor vessel
• Hydrogen generation, deflagration to detonation transition (DDT), and flame acceleration (FA)
• Status of severe accident management guidelines (SAMGs)
• Accident frequency analysis and probabilistic risk assessment
• Core and contention damage mitigation analysis
• Corium stabilization in reactor vessel/in containment
• Severe accident code assessment, validation, and application
• Containment loads and structural response
• Analysis of boron injection/dilution
• Experimental investigations in severe accidents
• Fuel degradation in the spent fuel pool
• Fission products behaviors and source term evaluation

Before submission authors should carefully read over the journal's Author Guidelines, which are located at http://www.hindawi.com/journals/stni/guidelines/. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/ according to the following timetable:
