Species sensitivity and dependence on exposure conditions impacting the phototoxicity of TiO2 nanoparticles to benthic organisms

by John Wiley & Sons, Ltd.  (Mar. 21, 2014)

Toxicity of TiO2 nanoparticles (nano‐TiO2) to aquatic organisms can be greatly increased upon exposure to ultraviolet radiation (UV). This phenomenon has received some attention for water column species; however, investigations of nano‐TiO2 phototoxicity for benthic organisms are still limited. In this study, bioassays of 3 representative ...

An ontological approach to knowledge management for sustainable nuclear decommissioning

by Inderscience Publishers  (Jan. 30, 2014)

Nuclear decommissioning design and operational knowledge may remain relevant over many decades. Designing sustainable operations today requires meaningful simulation of future events, which in turn relies on the accurate representation of all relevant current knowledge. In decommissioning, human agents may be as important for maintaining ...

Nuclear energy: societal and knowledge management aspects

by Inderscience Publishers  (Jan. 30, 2014)

Multidisciplinary complexity and special characteristics of nuclear energy management lead to varied public perception of associated risks. Arguments on how nuclear power plants might contribute to sustainability or threaten it are discussed. Energy produced from nuclear power reactors may contribute to the economic development of the country they ...

The role of the trade unions in fostering safety culture

by Inderscience Publishers  (Jan. 9, 2014)

Trade unions can play a relevant role in managing active policies on safety at work, above all in nuclear activities. Italian experience in safety at work is in the vanguard and has produced noteworthy outcomes. A significant figure is the Safety Workers' Representative (SWR), directly elected by workers. The SWR has four basic rights: to be ...

Sogin: best practice in supplier qualification

by Inderscience Publishers  (Jan. 9, 2014)

The purchasing and procurement policy of the Italian Sogin company, which is engaged in the reclamation of nuclear sites and management of radioactive waste, helps to ensure safety and quality during all work stages so as to protect workers, citizens and the environment.Keywords: Sogin, Nucleco, nuclear decommissioning, radioactive waste, waste ...

Radioactive waste management in Italy

by Inderscience Publishers  (Jan. 9, 2014)

After a short review of radioactive waste origins and inventories in Italy, the paper deals with the current major challenges that Italy has to cope with to pursue its radioactive waste sustainable management and safe disposal. Site restoration by Sogin of dismissed nuclear installations is part of the waste management challenge. The importance of ...

Common sense considerations on nuclear safety today

by Inderscience Publishers  (Jan. 9, 2014)

Several recent astonishing events at nuclear plants are recalled in this paper. These events are of the type of 'possible but not credible' events. The Fukushima tsunami (2011) is the most recent and catastrophic one. A discussion is made on the present (very conservative) safety philosophy and on the reasons why, notwithstanding it, catastrophe ...

Operational and decommissioning safety

by Inderscience Publishers  (Jan. 9, 2014)

The paper highlights the safety aspects during the operational and the decommissioning stages of a nuclear power station. It discusses the safety issues that must be taken into account starting from the design stage until the final restoration of the site. Also, the safety of the plant extension life is mentioned.Keywords: decommissioning safety, ...

US NRC progress in source term evaluation

by Inderscience Publishers  (Dec. 2, 2013)

In this paper progress in the source term evaluation is presented. This paper presents the development of source term evaluation of Nuclear Power Plants (NPPs) for Probabilistic Risk Assessment (PRA) for operation and licensing of the NPPs. Substantial research had been carried out by NRC, for this purpose. Nuclear Research and Development (R&D) ...

Photodegradation of chlorpyrifos in water by UV/H2O2 treatment: toxicity evaluation

by IWA Publishing  (Nov. 29, 2013)

Chlorpyrifos (CP) is an organophosphorus pesticide widely used in agriculture. Due to its toxicity, it has been necessary to develop a treatment to eliminate the environmental wastes generated by this substance. The combination of UV radiation and hydrogen peroxide seemed an interesting option to reduce the concentration of CP in water, as it has ...
