The nuclear power plant and waste repository are hazardous environments with gamma and neutron radiation being the main danger factors, particularly within the “in-containment” areas. To successfully monitor the activities within these harsh environments is of key importance. Surveying and assessing the status and functionality of all key equipment is one important factor. The other ...
This paper proposes the application of Direct Contact Membrane Distillation (DCMD) coupled with a nuclear reactor for water desalination and for low- and medium-level radioactive liquid waste concentration. Both laboratory and pilot plant experiments were carried out using the membranes reviewed in Part I of this paper. The effects of process parameters on the productivity and quality of DCMD ...
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 ...
According to the nuclear legislation in Sweden, companies licensed to operate nuclear power plants have overall responsibility for safely managing all nuclear waste and to pay all expenses regarding final disposal. A committee was set up by the Government to explore the requirements in the present legislation, and if necessary, make proposals for improvements. The committee proposed that the ...
Five waste streams are reviewed in this technical report: sewage sludge, construction and demolition waste, waste oils, waste from coal-fired power plants and biodegradable municipal waste. The review focuses on the quantities of wastes produced and on systems used to collect and treat them in several European countries and ...
Global reserves of mineral phosphorus are finite and the recycling of phosphorus from wastewater, a significant sink for phosphorus, can contribute to a more sustainable use. In Germany, Switzerland, and the Netherlands, an increasing percentage of municipal sewage sludge is incinerated and the contained phosphorus is lost. This paper reviews current technologies and shows that a complete ...
A new treatment successfully removes arsenic, selenium, and mercury from a variety of waste streams. Arsenic, selenium, and mercury occur widely in nature, though at low levels, and are associated with sulfide ores, elemental sulfur, and in crude oil and coal deposits. These metals are used in the manufacture of numerous industrial products, such as semiconductors, fuel cells, photographic ...
A methodology for criticality safety analyses with burn-up credit application has been developed for the WWER spent fuel management facilities. This methodology is based on two worldwide-used code systems: SCALE 4.4 for depletion and criticality calculations and NESSEL-NUKO for depletion calculations. The methodology is in the process of extensive validation for WWER-440 and WWER-1000 spent fuel ...
Mercury has long been recognized as a serious global pollutant that has a significant impact upon our ecosystem. Unlike most other pollutants, it is highly mobile, non-biodegradable, and bio-accumulative and as a result has to be closely monitored to ensure its harmful effects on local populations are minimized. Approximately 50 tons of mercury particulates are emitted into the atmosphere every ...

A major source of waste water in many power plants is the waste stream that results from ion exchange used for demineralizing the boiler feed water. The alkaline regeneration waste stream produced by the ion exchange process requires the addition of an acid to this stream before discharge from the plant. Regulatory authorities typically require the effluent to have a near neutral pH before ...

The U.S. Environmental Protection Agency Performance Track Program is a prestigious program that recognizes the accomplishments of manufacturing facilities that lead the way for improving their facilities’ environmental performance (i.e. reduce air emissions and consumption of water). Brooklyn Navy Yard Cogeneration Partners L.P. is an elite member of this program. They have been ...
The oxygen concentration in the flue gas of a combustion process such as that of a power plant or a waste incinerator gives a good indication of the efficiency of the combustion process. The parameter is therefore of great interest to optimize fuel economy, but also to control and reduce emissions of air pollutants. An ideal combustion process only results in CO2 and water, but if the air ...
Continuous emissions monitoring (CEM) is about monitoring air pollutants generated by a specific activity and emitted to the ambient air, typically through a tall stack or other exhaust pipe. The “activity” can be some industrial process like a power plant or a waste incinerator, but it can also be on a much smaller scale such as a car equipped with an internal-combustion engine. The ...
Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...
Vitrification and cementation are used for conditioning liquid radioactive waste (LRW) at SIA 'Radon'. More than 2000 m³ of LRW are treated on the vitrification plant and 100,000 m³ of LRW on cementation plants. For clearing LRW are used the filtration, ultra filtration, reverse osmosis, selective sorption, ion exchange, and oxidation. For treatment NPP bottom concentrates the technology of ...
The principal objective of the paper is to present operating experience in management of radioactive metal waste, originating at nuclear power facilities of the Russian Federation. Issues of radioactive metal waste recycling by melting, with the purpose of unrestricted re-use in industry, or restricted re-use within the nuclear industry, have been considered. The necessity for using a method of ...
