European Diamond University Sets Up Forum on Nuclear Decomissioning Techniques
20 May 2011
In the aftermath of the Japanese earthquake and the damage to the nuclear reactors at Fukushima Daiichi nuclear plant, it is timely that the European Diamond University is launching its Special Council about Nuclear Decommissioning. Sponsored by leading European diamond tooling company, Carbodiam, the forum has been set up to discuss social, regulatory, scientific and technical aspects of decontamination, decommissioning, re-utilization and waste management supported by cutting, drilling and grinding diamond tool technologies.
With many nuclear plants around the world reaching the end of their working lives in the coming decades, it will be important to share practical experiences of dealing with all aspects of decommissioning. So, the objective of the new council is to ensure the maintenance and development of decommissioning skills, promote good practices and services in view of protecting communities around deactivated nuclear sites.
The first planned event organised under the auspices of the council will take place in mid-September and, depending on the number and origin of applicants, several sessions are likely to take place at Carbodiam’s different manufacturing sites in Germany, France, and Belgium. The sessions will include updates on lessons learned from international projects and technological developments in the area of Nuclear Decommissioning, Waste management, site closure, and legacy management, in addition to a comprehensive technical training. As part of the event, there will be visits to the company’s diamond tool factory, R&D laboratory and some live presentations at its demonstration and testing site. The event will also be sponsored by several other European diamond tool manufacturers, or equipment suppliers, partnering for that specific topic.
Expertise on tap
Carbodiam has an established Nuclear Decommissioning Team aims to support organizations and companies working in the nuclear field. The company’s focus is on continuously improving the tools, techniques and processes supporting the nuclear plant construction, refurbishing, waste management facilitation, nuclear plant de commissioning and management of radioactive waste.
This team is built around five experts in the diamond tooling industry who, together, have more than 100 years experience. The experts are:
• Bernard Delannay – Diamond Grinding and Wet Cutting Techniques
• Erico Mariotti – Diamond Wire Cutting Techniques
• Adrian Eglin – Diamond Dry Cutting Techniques
• Uwe Neidhardt – Diamond Grinding and Surfacing Techniques
• Lorenz zur Nedden—Drilling techniques
Their expertise is backed by technical solutions and products developed by Carbodiam for cleaning and dismantling hazardous material for all types of industries, including sensitive areas. These proven processes are alternative technologies and solutions for cleaning, deactivating and decommissioning nuclear sites. Carbodiam has a good understanding of the future requirements of nuclear decommissioning as well as refurbishment of nuclear plants.
Carbodiam’s experience with other sensitive industries in the technical aspects of decontamination, decommissioning, reutilization and waste management is directly duplicable to nuclear sites legacy management. Carbodiam’s world-wide expertise is an asset for nuclear site sanitation, replanting, closures and clearance of redundant equipment.
Tasks such as asbestos removal, removal of led containing coatings, de-fuelling, pond decommissioning and rationalization of decontamination systems require highly professional tools/equipment and technical support. The challenge is to accelerate hazard reduction taking into account the safety, security and environmental performance but keeping in mind that every solution needs also to be cost effective!
Carbodiam solutions, technologies and expertise in surfacing, drilling, dry cutting, wet sawing, wire cutting are very valuable assets in civil nuclear legacy management.
It supports processes such as:
• De-radiation and remote cleaning to target dose rate level to permit man entry.
• Remote handling for dismantling sites and installations having contained radioactive material.
• Removal of wing walls, shield doors and final decontamination of internal cave surfaces to de-mining level.
• Wire cutting for metal and concrete items.
The Cobrator Carbodiam Diamond wire range covers five different versions from 8.8mm to 15mm diameter. Cobrator diamond beads and wires and provides not only a long life but also exceptional speed. This range has been extended with a new electroplated wire for more extreme and complex situations and is designed either to cut reinforced concrete with a reduced amount of cooling water or full steel on a dry basis. This permits to use the diamond wire on critical sites such as nuclear decommissioning where the contamination and waste treatment is a vital issue.
