  • Assessment of uncertainty in discrete fracture network modeling using probabilistic distribution method

    There have been widespread concerns about solute transport problems in fractured media, e.g. the disposal of high-level radioactive waste in geological fractured rocks. Numerical simulation of particle tracking is gradually being employed to address these issues. Traditional predictions of radioactive waste transport using discrete fracture network (DFN) models often consider one particular ...

  • Socio–environmental nuclear conflicts: the case of El Cabril

    Since the commissioning of the 'El Cabril' Central Storage Facility for Low– and Intermediate–level Radioactive Waste (hereafter 'El Cabril'), most people living in nearby towns and villages have regarded this nuclear facility with a marked degree of rejection and distrust. This study examines the process of analysis, management and intervention specifically designed and implemented with a view ...

  • Radioactive waste buried beneath Runit Dome on Enewetak Atoll, Marshall Islands

    In the early 1970s after extensive characterisation of fallout the US Pacific Proving Grounds located at Enewetak Atoll began rehabilitation in preparation for the return of indigenous people who were relocated during the Cold War. Cleanup entailed removal and collection of ∼545 GBq of contaminated topsoil, vegetation, and debris (concrete and metal) that was subsequently entombed within an ...

  • Need a swifter, safer way to mop up toxic waste? Blue goo may do.

    Scouring radioactive waste usually means just that. Scrub with soap and water, pails and brushes. Repeat. If it sounds messy, it is—and dangerous too for those exposed to dust and contaminated wastewater.  Hawaii-based CBI Polymers says it's come up with a better way to clean up nuclear waste. The firm's blue goo may not look high-tech; all you do is pour it. But as the superabsorbent ...

  • Counting solutions LSC technical tips from PerkinElmer

    The advance of the nuclear industry in all its forms coupled with growing concerns for possible environmental contamination has led to an increased interest in the quantification of radioisotopes in the environment. Radionuclides currently present in the environment originate from a variety of sources such as fallout from nuclear weapons testing, and in discharges from both nuclear and ...

  • Optimisation of processes in a two-stage installation for liquid radioactive waste immobilisation

    A two-stage installation for liquid radioactive waste (LRW) immobilisation is intended for LRW reprocessing with the objective to include radionuclides into solid vitreous matrix. Depending on the processing scheme of immobilisation, an installation for LRW immobilisation may include one or more devices. This paper describes a developed mathematical model of a two-stage installation for LRW ...

  • Selection and design criteria of supported liquid membrane for the treatment of rad-waste

    Supported Liquid Membrane (SLM) is an emerging trace metal pre-concentration technique. It has the ability to decontaminate radionuclides even from lean secondary effluent. SLM can be considered as a part of process intensification, which implies a closed loop operation. It has reduced space requirement as well as minimised secondary effluent generation and the number of unit steps. Proper ...

  • Knowledge management for radioactive waste disposal: moving from theory to practice

    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 associated Performance Assessments (PAs). ...
