Case Studies
Gaseous Sampling & Monitoring Cubicle Refurbishment
The particulate and sulphur 35 (S-35) gaseous discharge monitoring panels at Hinkley Point B required upgrades.
B/G/90 Valve Installation
EDF Energy – Hinkley Point B
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.
Replacement CCR Hardwire Fire Alarm System
EDF Energy – Hinkley Point B
AMS provided a detailed design for a replacement hard wired fire alarm system for Hinkley Point B Nuclear Power Station.
Reactor CO2/ O2 Injection System
EDF Energy – Heysham 1
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
Superheater Overpressure Instrumentation Replacement
EDF Energy – Dungeness B
AMS was tasked to find a suitable modern replacement for the two signal isolators and the power supply based upon an item equivalency evaluation.
RAETP Alarm Management System
EDF Energy – Heysham 1
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.
Cold Eye Review – Level Control System
EDF Energy – Hartlepool
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.
Stator Water Caustic Dosing System
EDF Energy – Heysham 2
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.
EMI/ RFI Resilience – Surveys, Recommendations & Modifications
EDF Energy – Several Sites
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.
