Ageing & Obsolescence
Replacement CCR Hardwired 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.
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.
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.
Alternative Indication Centre (AIC) – Scada System Upgrade
EDF Energy – Hinkley Point B
AMS partnered with Servelec Controls (Now ITI) to deliver a new SCADA system that mimics the functionality of the existing system.
PA System Technical Support
EDF Energy – Sizewell B
AMS provisioned a Senior C&I Engineer with suitable qualifications and experience in working on PA systems to establish thorough visual inspections.
Polar Crane
EDF Energy – Sizewell B
AMS’ report needed to specify component qualification requirements, recommend modern component equivalents and substantiate the use of these components on a technical basis.
PCB Reverse Engineering
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.
Sludge Tank Level Monitoring
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.
