AMS Nuclear delivered nuclear-grade gas measurement and effluent monitoring systems for Hinkley Point C. Six measuring gas cabinets, flow proportional samplers and analysers, all seismically qualified, built to nuclear standards and delivered on schedule.
This project demonstrates our ability to deliver proven, safety-critical systems for the UK's most important new nuclear facility.

Nuclear Safety Critical Gas Measurement Systems for Hinkley Point C
Executive Summary At Hinkley Point C (HPC), EDF required robust gas measurement and effluent monitoring systems to meet stringent safety,…
This project involved the design of a modification to valve B/G/90 to provide automatic operation of the valve to overcome the potential local hazards which could prevent isolation of the system if a seismic event were to occur.
Gaseous Activity Monitoring (GAM) System – Installation Assistance
EDF Energy – Heysham 1
To assess the interface feasibility and detailed design which will be required prior to the installation of the new fleet wide Gaseous Activity Monitoring (GAM) system.
AMS designed, built, tested, delivered and site tested a flow monitoring and valve control panel for the oxygen injection system to be used at Heysham 1 power station
The existing RAETP (Radioactive Active Effluent Treatment Plant) alarm panel showed signs of ageing and needed replacing with a new alarm panel with the same functionality and maximum size.
AMS was asked to provide a cold eye review of the TG2 Turbine Extract Condenser (TEC) Level controller system that had proven problematic following an upgrade.
Due to chemical control issues with TG7 and 8 stator winding cooling water systems, there became a requirement to improve the pH control within the circuit.
AMS has undertaken detailed site walk downs on some stations and produced optioneering reports providing recommendations for the individual panel modifications to improve cabinet RFI resilience.
AMS evaluated the proposed EDF concept design and expanded the concept whilst working closely with the site engineers to ensure the system was fit for purpose and compatible with existing infrastructure.
AMS will undertake detailed site walk downs of the required stations and produce optioneering reports providing recommendations for the individual panel modifications.
AMS’ report needed to specify component qualification requirements, recommend modern component equivalents and substantiate the use of these components on a technical basis.
AMS’ scope was to utilise the existing controls and indications within the CCR whilst providing an interface which allows the controls and indication to operate with either the old or new plant
AMS undertook a site survey and produced a detailed P&ID of the existing system before completing the detailed design, build, installation and commissioning activities.
The Automatic Boiler Depressurisation System (ABDS) and Reactor Safety Relief Valve Isolation (SRVI) System were two of the three modifications being prioritised for immediate implementation at DNB.
Following the final shutdown and defuelling of Hinkley Point ‘A’, AMS delivered a new and separate C&I ‘overlay’ system to meet the plants monitoring and communication needs for the next phase of decommissioning.
The Public Address (PA) system at Hinkley Point ‘A’ was suffering the effects of ageing and obsolescence. AMS were contracted to conduct an optioneering study and to ultimately implement a replacement system.
When an old piece of instrumentation became obsolete, AMS reverse engineered the PCB enabling the client to avoid the costly exercise of qualifying a new piece of equipment for the application.
As part of a boiler lifetime modification program, AMS were engaged by the client to design, substantiate, build, test and deliver a suite of instrument cubicles to support a risk reduction initiative to meet the station’s Safety Case.
AMS was contacted by a client to utilise our instrumentation expertise to propose a solution to an obsolescence issue surrounding the level measurement of radioactive effluent in a nuclear power station’s effluent storage tanks.
