NSG Decommissioning Newcastle University Cyclotron

NSG Environmental Ltd is delighted to announce it was recently awarded a contract to decommission and dispose of an ABT Biomarker Generator (BG-75) cyclotron at Newcastle University.

The redundant equipment was previously used for the production of positron emitting isotopes for radiochemistry/pre-clinical positron emission tomography (PET). The space currently occupied by the cyclotron is required for a new laboratory at the North East research university. Having recently decommissioned cyclotrons at GE Healthcare’s Amersham site, NSG’s vast nuclear decommissioning and waste management experience was a key factor in being awarded the contract.

The project is expected to be completed by the end of 2019.

NSG to Supply and Install Upgraded Effluent Samplers at Hunterston B

NSG Environmental Ltd is delighted to announce it was recently awarded a contract for the supply and installation of two upgraded Flow Proportional Liquid Effluent Samplers (FPLES) at EDF Energy’s Hunterston B site in Scotland.


For over 20 years, NSG has provided a maintenance service to all of the original FPLES installed at EDF Energy and Magnox nuclear power stations. During this period, a number of sampler components and critical spares became increasingly obsolete and NSG identified the need for an upgraded sampler that is fully supported with readily available components and critical spares. The Mark II design replicates the service connections and functional requirements of the original sampler whilst minimising redundancy and obsolescence.

The technology consists of small aliquots being taken at frequent intervals to ensure changes in discharge volume and rate are not overlooked whilst providing a manageable qualifying sample. The sampler provides a consistently reliable representative and proportional sample of liquid effluent, including any particulate present, for testing and analysis, plus an accurate indication of total discharge volume. Operational benefits of the technology include minimal operator intervention and low maintenance requirements.

NSG Secures Place on Dounreay Decommissioning Services and Works Framework

NSG Environmental Ltd is delighted to announce it has secured a place on the Dounreay Decommissioning Services and Works Framework as part of the AECOM E&C UK team.

The framework has a seven-year duration (4+2+1) and an anticipated value in the region of £400m. Opportunities include a number of major projects at the Scottish nuclear licensed site, such as the construction of a size reduction facility, shaft and silo decommissioning, and the demolition of historic active laboratories.

The team, led by AECOM, also includes influential partners Exyte Hargreaves, Kier Infrastructure and Overseas, Morson Projects, NIS Ltd, Squibb Group and Westinghouse Electrical Company UK.

Jim Porter, Managing Director of NSG, commented:

We are absolutely thrilled to secure a place on the framework and look forward to collaborating with our partners to deliver success on one of the most complex nuclear decommissioning projects in Europe.

Collaboration Success for NSG-Cavendish-Sellafield R&D Project

The project team during trials at NSG’s facility (from left to right): Chris Mould (Sellafield), Karen Allen (Cavendish Nuclear), Stephen Lloyd (Sellafield), Rob Hughes (NSG), Rachael Wills (Sellafield) and Dave Blackburn (NSG)

NSG Environmental Ltd is currently working with Sellafield and Cavendish Nuclear via the Design Services Alliance (DSA) framework to evaluate a technology for Magnox sludge resuspension. The project is part of a programme of work currently being undertaken by Sellafield to retrieve and process sludge stored in the FGMSP SPP1 Bulk Storage Vessels. The primary aim of the project is to test the effectiveness of the Pulsair Tote Stick to resuspend Magnox sludge prior to pumping and subsequent waste processing.

Sellafield recently placed the contract with Progressive through the DSA, which was flowed down to NSG because of their experience, facilities and collaborative approach. The team has mobilised quickly and the early trials are now being carried out at NSG’s R&D facilities in Chorley, Lancashire.

As part of the work, NSG is manufacturing a series of sludges with different formulations and properties to replicate a range of challenging environments that potentially may be faced on Sellafield site. Magnesium hydroxide powders are used to simulate the physical properties of the corroded Magnox sludge, while tungsten powder and tungsten pieces are used to represent the potential for dense metallic debris that may occur within the pond waste stream.

NSG is adding value to the trials through their ability to repeatedly manufacture the range of sludges to a consistent specification. In support of this, they also have equipment to test, sample and analyse sludge samples within their laboratory for rheology and particle size measurement. Cavendish is adding value to the team through their programme management and design input.

Early results are showing promise and, if successful, there is a plan to develop the work further through full-scale testing and potential future inclusion within a larger system on site.

Stephen Lloyd, Process Engineer and Technical Lead for Sellafield, commented:

It is great to see Sellafield, Cavendish and NSG collaborating to quickly evaluate technologies which can potentially add real value to the Legacy Ponds work programme.

Major Milestone Reached on LLWR Decommissioning Project

A major milestone has been reached on the LLWR PCM Decommissioning and Demolition project with the transition of a magazine to C2 radiological classification.

Magazine 10 is the first of four remaining magazines scheduled to be fully decommissioned and it is now possible to enter the magazine without any respiratory protection for the first time since the magazines were filled with PCM (plutonium contaminated material) waste over 20 years ago. This marks a major achievement for the project, which NSG has been delivering as part of an integrated team on the site for the last five and a half years. In this time, the facility has been transitioned from C5, the highest contamination-controlled area classification, to C3 and now finally C2, where only a pair of overshoes is required to enter in addition to the standard ‘Site Basics’ clothing.

Gareth Wilson, NSG’s Project Manager at LLWR, commented:

The decommissioning activities undertaken by the project team to achieve this milestone have been vast and included some significant challenges. A number of the tasks have involved closely managing significant risks in terms of conventional safety whilst working in high hazard contamination-controlled areas. The team have worked vigilantly to complete all tasks safely and have delivered all the decommissioning scope without a single lost time accident.

A Dream Placement at NSG for Dominic

Last week, NSG welcomed A-level student and chemistry enthusiast Dominic Jackson from West Lakes Academy for the Centre for Leadership Performance’s Dream Placement initiative.

During his Placement Week, Dominic spent his first day at NSG’s head office in Chorley, where he interviewed Managing Director Jim Porter and learned about the nuclear industry. For the rest of the week, Dominic was based at the Low Level Waste Repository in West Cumbria and shadowed members of the NSG site team. Whilst there, Dominic attended project meetings; chatted with engineers, project managers and planners to gain an insight into the different office-based roles; supported the project team with data collection and other project tasks; and received a bespoke tour of the site to witness operations.

Lesley Wood, HR Officer and Dream Placement representative for NSG, commented:

It was great to have Dominic with us for the week and we hope he had an enjoyable and educational experience. There are lots of exciting career opportunities available in the nuclear industry and Dream Placement enables students like Dominic to experience them first hand.

Dominic’s Dream Placement will conclude at the Showcase Event at Energus in Workington in late March, where he, Lesley and the rest of the participating students and company representatives will get back together to discuss their Dream Placement experiences.
