There are several risk-sensitive industries like air traffic, nuclear power generation, dangerous chemical processes, etc. The technical solutions used are usually well approved and widely known; the occasional problems usually originate from the not-careful-enough design, the insufficient risk assessment, the unsatisfactory training and mismanagement. With proper operation and waste management...

ENRESA is the national company in charge of radioactive waste management in Spain. The company was set up in 1984, and one of its missions is the dismantling of nuclear facilities. ENRESA has carried out the dismantling of the Vandellós 1 nuclear power plant, several research installations and a pool type experimental reactor and is currently initiating the dismantling of the José Cabrera nucle...

The issue of waste management has been studied simultaneously along with the development of the ARIES heavy-ion-driven inertial fusion energy (IFE) concept. Options for waste management include disposal in repositories, recycling, or clearance from regulatory control, following a reasonable cooling period. This paper concerns the feasibility of recycling the heavy-ion-beam targets, in particula...

The issues of waste generation in batch process plants differ in many aspects from those in continuous plants. Despite the smaller-scale of processing, complexities from discontinuities and run-to-run variations make waste minimization in batch plants more challenging. In this paper, we introduce an integrated qualitative-quantitative methodology and decision support system, called Batch-ENVOPE...

14C is one of the limiting radionuclides used in the categorization of radioactive graphite waste; this categorization is crucial in selecting the appropriate graphite treatment/disposal method. We propose a rapid analysis method for 14C specific activity determination in small graphite samples in the 1-100 μg range. The method applies an oxidation procedure to the sample, which extracts 14C fr...

This paper is to illustrate the experience and future plans for decommissioning Italian NPPs, and the new organization, set to manage the whole decommissioning problem. Italian NPPs were shut down in the 1980s, and “deferred decommissioning (SAFSTOR)” was the selected decommissioning strategy, due to the lack of a repository for the disposal of radioactive waste. In 1999 the liberalization of t...

Nuclear hazards, linked to both U.S. weapons programs and civilian nuclear power, pose substantial environment justice issues. Nuclear power plant (NPP) reactors produce low-level ionizing radiation, high level nuclear waste, and are subject to catastrophic contamination events. Justice concerns include plant locations and the large potentially exposed populations, as well as issues in siting, ...

Due to an increase of the nuclear power plant, radioactive waste is also increasing trend and due to the large amount of radioactive waste disposal costs also increase. Decontamination of soil contamination is depending on the soil characteristics and environmental factor, so single decontamination method is difficult for effective decontamination. We need innovative method to decontamination, ...

most of electricity is generated by thermal power plants in iran. shahid rajaee thermal power plant consists of four 250mw natural gas and fuel oil burning units that is located at 100 km west off tehran. as a result of fuel oil burning in winter time, boilers air heaters are washed and cleaned frequently. the wastewater originating from air heater washing contains suspended solids and differen...

The waste water showed high values of total solid (TS), hardness and chloride with slightly alkaline pH along with high concentrations of Cr (2.03 mg l(-1)), Ni (1.59 mg l(-1)) and Zn (0.46 mg l(-1)). The concentration of Cu (0.21 mg l(-1)) and Zn in industrial waste water was low than Ni and Cr. The diluted (25 and 50%), undiluted (100%) waste water was used to irrigate the lettuce plants grow...
