Technical Support to Vitrification

NNL has more than 35 years' experience in providing nuclear waste vitrificiation technical support. The majority of our work has been in support of HLW vitrification at Sellafield site. And for the last 25 years, our main focus has been in support of the Waste Vitrification Plant (WVP) and the AVH process.

Our Service

NNL's expertise and experience comes from our professional team of technologists and engineers who have an in-depth understanding of the WVP process and the operation of its equipment. NNL is frequently involved in supporting operations and monitoring plant performance via direct plant contact and by using the Apentech Process Explorer plant data monitoring system. We also have our own on-line capability to monitor live plant data. And in addition we have substantial knowledge of the relevant chemical and effluent flow sheets. Our work is widely recognised by the WVP management and technical support teams and our expertise, responsiveness, flexibility and advice are all appreciated.

Benefits of Our Service

The professional service NNL provides includes:               

  • Troubleshooting of operational problems
  • Advice on unusual plant conditions
  • Quality assurance and non-conformance with product specification

We are key members of our customers' High Level Waste Technical Committee and the Product Quality Review Committee. We provide an independent body of experts who peer review plant technical issues.

NNL will continue to provide ongoing support to the continued operation of high-level waste vitrification at Sellafield through the life cycle of these plants including POCO and decommissioning.
