Decommissioning & waste management

Many of the world’s nuclear facilities will be reaching the end of their active life over the next 20 years. The clean-up and management of the nuclear legacy is one of the most demanding challenges facing the industry. 

Amec Foster Wheeler has a long track record of working on the world’s most complex nuclear decommissioning sites. Two prime examples include the world’s largest decommissioning contract, Ignalina in Lithuania, where we were responsible for the programme management; and the Decommissioning Framework Contract at the Sellafield site in the UK. 

Waste management
Waste management is essential in the clean-up of any nuclear facility or site. Our services provide customers with solutions in waste characterisation, through waste minimisation and processing, to the transportation and safe final disposal of the hazard. 

We have operations in Slovakia and Czech Republic that specialise in: 

  • Radiological monitoring using broad range of techniques from manual to highly sophisticated applications of remotely operated vehicles (ROVs)·
  • Removal and separation of radioactive sludge from the storage tanks using the ROVs and subsequent in-situ treatment
  • Design and implementation of bespoke decontamination services
  • Automatic system for measurement of gamma activity for free release or waste characterisation
  • Repackaging of wastes in historical repositories 

Our commitment to safe and efficient on-site operations demand highly skilled and innovative project management, and our project teams focus on ensuring that our customers’ requirements are met. 

Amec Foster Wheeler has world class experience of decommissioning in the UK, Canada, Eastern and Western Europe, Lithuania, Ukraine, Armenia and Russia. We offer a complete range of nuclear services that span the full life-cycle of any decommissioning project, from developing the initial concept through to hands-on decommissioning and clean-up. 

With our safety, health physics and environmental support we act as a single supplier, delivering the full range of skills and services for the completion of any decommissioning project; managing the decontamination and decommissioning of facilities to minimise the environmental impact and pave the way for site regeneration. 

In support of our decommissioning and waste management activities, Amec Foster Wheeler provides Radiological and Environmental services, which give essential support to our customers, other contractors and our own project teams.

<div>A technique for immobilising, solidifying and encapsulating nuclear waste in a safe and cost-effective way. It has been used successfully at a number of nuclear power plants in Europe over the past 20 years. SIAL<span style="vertical-align: text-bottom; font-size: xx-small;">®</span>&nbsp;can be used on site, saving the customer significant time and cost. It enables the transformation of radioactive wastes into a much safer, solid form which is easier to handle, transport and store.</div><div>&nbsp;<br /></div><div>The SIAL<span style="vertical-align: text-bottom; font-size: xx-small;">®</span>&nbsp;technique can be used on low, intermediate and higher-level radioactive wastes, including ion exchange resins, spent fuel debris, borates, organic liquids and incineration ash. As a geopolymer, it is superior to cement because it can incorporate significantly more waste into the matrix, thus saving disposal costs. The physical characteristics of the final product means it performs better in terms of compressive strength and leachability.</div><div>&nbsp;<br /></div><div>In 2010, The World Association of Nuclear Operators and the Operational Safety Review Team evaluated the SIAL<span style="vertical-align: text-bottom; font-size: xx-small;">®</span>&nbsp;matrix technology at Dukovany nuclear plant in the Czech Republic, as an example of best practice.</div><div><br /></div><div><ul><li>It encapsulates nuclear waste in a safe and cost-effective way</li><li>It immobilises and solidifies waste</li><li>Ion exchange resins, spent fuel debris, borates, organic liquids &amp; incineration</li><li>Cited as good practice by IAEA</li></ul></div>

ORION ScanSort<sup>SM</sup> is a portable, conveyor-based system for laboratory quality radiometric scanning and real-time segregation of radioactive material. ScanSort<sup>SM</sup> offers significant benefits over traditional sorting methods because it: <UL> <LI>Reduces waste volumes by up to 95% <LI>Scans excavated materials precisely and accurately <LI>Sorts material to nuclear regulators specifications <LI>Cuts transport and disposal costs <LI>Provides peace of mind for clients, regulators and local communities.</LI> </UL>
