radioactive waste management Articles

The exponential growth in the knowledge base for radioactive waste management is a cause for concern in many national programmes. In Japan, this problem is exacerbated by a volunteering approach to siting of a deep geological repository, which requires particular flexibility in the tailoring of site characterisation plans, repository concepts and ...

With an increase in the use of nuclear energy, radiation and radioactive substances, it is essential to invigorate, reinforce and enhance the effectiveness of the elements of national radiation protection and safety infrastructure. This also includes the addition of feasible and affordable ways and means to the national safety infrastructure with ...

Starting in 2006, the International Atomic Energy Agency (IAEA) developed a guidance publication on knowledge management for radioactive waste management organisations. The publication is part of the IAEA Nuclear Energy Document Series at the level of Report. The purpose of the document was to provide guidance to the full range of decision makers ...

The EURATOM Basic Safety Standards provided the occasion to establish comprehensive clearance regulations in German law. The new German Radiation Protection Ordinance contains detailed regulations regarding clearance of radioactive substances with negligible radioactivity from practices subject to authorisation. For about 300 radionuclides, there ...

This paper gives a short overview of the activities of the Belgian Nuclear Research Centre (SCK?CEN) and the role it can play in the cooperative agreement that was established between the China National Nuclear Corporation (CNNC) and SCK?CEN. Indeed, the current established cooperation on nuclear energy research between China and Belgium should ...

The object of this paper is to present the 'Integrated Information System for Supporting the Inventory Control of Radioactive Waste' ? SICORR. The SICORR model considers the following items: the radioactive waste control inventory, encompassing the treatment and integration of the radioactive waste and the radionuclide data and processes; the ...

This paper proposes a procedure based on financial-option theory for establishing a fuzzy discount rate for radioactive waste management. Funding is made available in a dedicated fund for covering future liabilities, including technical-scenario uncertainties. Assets in the fund are managed according to some given strategic asset allocation. ...

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 ...

Activities on rehabilitation of eleven temporary radwaste repositories are currently underway at the RRC 'Kurchatov Institute'. Technologies used for exploratory drilling of repositories, their radiation survey, cleaning fill-up soil from the repository ceilings and opening the ceilings, RW extraction, sorting and packing in containers are ...

FACTS The State of Nevada, local communities, the nuclear industry1 and several environmental organisations challenged the statutory and regulatory scheme for the Yucca Mountain nuclear waste repository. There were three types of dispute. In the first group, challenges weremade to the regulations issued by the three regulatory authorities, namely ...
