Robotics for nuclear waste handling
This research focuses on the development of the control system of a dual arm industrial robot. A controller for the position control of unconstrained robot arm is also presented. System architecture, hardware configuration and software development are discussed in detail; The experimental set-up …

Automated robotics system for nuclear waste handling (hardware and software)
Hazardous materials handling involves the use of robotics manipulators, which are controlled by operators outside a sealed environment. The operator's reduced vision and decreased dexterity causes slower job performance and fatigue, which ultimately leads to mistakes. These mistakes can be …

An assessment of the potential for waste minimisation in small and medium enterprises in the South African metal finishing industry
… has recently (1998) been updated. The National Waste Management Strategy (NWMS), has clearly identified waste minimisation as an important part of future programs aimed at making waste handling practices in South Africa more sustainable. The waste minimisation approach has been applied in …

Levelized Cost of Fuel (LCOF) studies for microreactors using TRISO fuel in hydride and beryllium-based composite moderators in open and closed fuel cycles
… on demonstrated long-term TRISO fuel integrity. Waste handling also factors into the analysis. Deconsolidation—removing the inert moderator before disposal—can shrink spent-fuel volumes by more than 90%, easing repository demands. Continued R&D into advanced additive manufacturing, high-burnup …

Performance Evaluation of Condiments as Environmentally Friendly Corrosion Inhibitors for Amine-Based Carbon Dioxide Absorption Process
… not environmentally friendly and require costly waste handling and disposal. To reduce such cost and prepare for more stringent environmental regulations for chemical uses and disposal, this work investigated the feasibility of using condiments as environmentally friendly corrosion inhibitors in …

Moderately-rapid assessment of alkaline desiccation environmental systems
… was determined to be the limiting factor in some waste samples, resulting in the need to dilute the waste with local soils. Designs were developed to reduce the unnecessarily long detention times between 0.75 to 4.4 years and improve other features, especially additive use and waste handling. …

Policies to manage electronics waste : an analysis of US and EU regulatory initiatives
… associated with the disposal of electronics waste are being developed in the US and the EU. This paper offers a standard critique of those policies and also analyzes them in terms of the likelihood they will induce innovation in response to their requirements. The US proposal relaxes the …

A Study of University Hospital Health care worker's relevant factors of Medical Waste Management Practices
… of knowledge, attitude, and practice on medical waste among hospital employees, to identify the correlation of each, and to identify factors influencing attitude and practice of medical wastes. Data from 150 healthcare workers at a university hospital in Gyeonggi S city were collected using a …

Enhancing hydraulic performance of a multi-stage anaerobic digester for high solids cattle manure
… digestion is an attractive technology for waste handling because it converts low value waste material into energy and other useful products while performing necessary treatment for proper waste disposal. Conventional anaerobic digestion technology, however, has been met with many economic …

A System-Wide Model for Solid Waste Separation and Food Waste Discharge to Sewer Systems
… has resulted in a call to (1) convert wastewater treatment plants (WWTPs) to water resource recovery facilities (WRRF) and (2) diversion of organic waste (i.e., food waste) from landfills. Due to excess anaerobic digester (AD) capacities at most WWTPs, it has been proposed to co-digest …

The preparation and characterisation of highly selective adsorbents for fission product removal from acid solutions
… isotopes thereby preventing them from being wasted. This can save up to 30% of the natural uranium that is required each year for the fabrication of new nuclear fuel. A second aim is to reduce the volume of high-level radioactive waste. Along with the separation of uranium and plutonium there …

An Investigation of Major Component Disposal Costs for Advanced Nuclear Reactors
Waste disposal is an important aspect for decommissioning of Nuclear Power Plants (NPPs) that requires an understanding of the characteristics of the waste forms. The costs of disposal depend on the activity, volume, dose rate and waste handling/packaging. The U.S. average nuclear reactor age is 40 …

Sustainable waste management system for market waste in less economically developed cities: barriers and opportunities
The improper disposal of solid waste has become a significant concern, particularly in developing countries with poor waste management practices, where indiscriminate disposal on land, in the aquatic environment, and poorly designed and maintained landfill sites are now widely acknowledged as …
