An approach for the analysis and management of multiple criteria critical infrastructure problems is put forth. Nuclear waste management involves complex tradeoffs under uncertainty. Among all waste either generated by nature or human activities, radioactive nuclear waste is the most toxic to human health and difficult to manage: it is known that some nuclear waste material will be radioactive ...

The routine operation and maintenance of nuclear facilities generate quantities of radioactive material in many different matrices that are packed in many different sized containers. The waste is often packaged in large containers, such as 220 l drums, because process operators find drums more economical to handle than small containers. Based on regulations, the radioactivity and the radionucli...

en c= m m — < m The Waste Isolation Pilot Plant (lVIPP) is the first operational repository designed for the safe disposal of transuranic(TRU) radioactive \vastefrom the defense programs of the U.S. Department of Energy (DOE). The U.S. Environmental Protection Agency (EPA) is responsible for certifications and regulation of the WIPP facility for the radioactive components of the waste. The EPA ...

The radioactive waste containers, containing different radioactive materials, have to be characterized before their final disposal. Destructive methods, although being the most precise, are also the most expensive and not the easiest ones from the radioprotection point of view. In this situation, high resolution gamma spectrometry proved to be a reliable method for the non destructive assay met...

More than 167,000 m of mixed waste, waste that contains both chemically hazardous and radioactive components, are in the known inventory at DOE sites that formarly produced nuclear defense materials. The inventory contains both mixed low level wastes (MLLW) and mixed transuranic wastes (MTRU). Site cleanup and decommissioning activities during the coming years are expected to nearly double this...

human activities such as oil and gas production can enhance the natural level of naturally occurring radioactive materials (norm) in by-product and waste streams. iran has been among the top five oil producing countries since 2005. this high production rate emphasizes the importance of norm management to ensure the safety of humans and wildlife. petroleum storage and transport facilities are lo...

FOREWORD Plans for disposing of radioactive waste have raised a number of unique and mostly philosophical problems, mainly due to the very long timescales which have to be considered. While there is general agreement on disposal concepts and on the approach to establishing that disposal facilities are safe, consensus on a number of issues remains to be achieved. To assist in promoting discussio...

Assay of the radioactive content of waste drums is important for inventory and waste disposal purposes. The sampling of the drum content is a difficult, time and labor consuming procedure, involving special radiation protection considerations. On the other hand the characterization of waste drums containing radioactivity by measuring the drum as a whole (without opening) offers overall simplici...
