Van - Nuclear Decommissioning


A Wealth of Experience

We have our own radiological protection supervisor and have worked on several nuclear sites in the UK over the last decade. We operate at the Tier 3 specialist contractor level but do have the in-house capacity to operate as a Tier 2 supplier as well.

Innovative Solutions

We pride ourselves on developing innovative processes to deliver positive project outcomes.


We try, wherever possible, to apply existing technologies to nuclear-specific problems for issues such as blockage inspection and removal, liquid-solid separation, and conditioning of the collected solids. We have developed a set of environmentally safe water jetting procedures and can offer remote abrasive water jet cold cutting.


Almost all of our work in the sector is subject to commercial confidentiality and will not and cannot be posted. We are, however, more than happy to discuss how we might assist you to deliver your project objectives. Please call or email for initial discussions.
