One of the major challenges facing the nuclear industry, is the retrieval and immobilisation of liquid, intermediate and low level waste. Traditionally the approach to solving this problem has been to design and build bespoke systems on a site by site basis. This approach was both costly and time consuming.

Working with British Nuclear Group, NSG has designed and built a number of process plants based on a modular design principle. This not only enables the plant to be transported from site to site, but also be operated on a campaign basis. Work began on this concept in 1988, and since then NSG has built three waste encapsulation plants and has completed over 30 campaigns, processing more than 380,000 litres of waste.

In parallel with this work, NSG has been involved in the design, build, installation and operation of mobile plants for processing intermediate level waste by cementation and minimising waste through dewatering.

NSG has provided operational support to British Nuclear Group for the retrieval and solidification of low and intermediate level waste for over 10 years. Through this we have developed the capability of operating nuclear plant on most of the UK nuclear licensed sites. Whilst this service is provided as a planned operational programme, we are also able to provide a rapid response to unplanned events in many instances.
