Adelard partner, Dr Sofia Guerra presented a series of papers to an influential audience from the nuclear industry at the 11th International Conference on Nuclear Plant Instrumentation, Control, and Human-Machine Interface Technologies (NPIC & HMIT 2019), February 9-14, 2019, Orlando, USA.
NPIC&HMIT is the de facto forum for nuclear instrumentation and control (I&C) and human factors engineering (HFE) professionals to meet with leaders in industry and academia, discover the state of the technology, exchange information, and discuss future directions.
Sofia presented the following papers:
- Justifying PLC-based applications with limited cooperation from platform supplier - the COGS approach
Several control and monitoring applications are implemented using commercial-off-the-shelf (COTS) PLCs that were not necessarily developed according to nuclear standards. The UK nuclear regulatory regime requires that a safety case be developed to justify and communicate their safety.
This paper describes the Class 1 assessment of the Rosemount 3051 Pressure Transmitter and the Class 2 assessment of the Rosemount 644 Temperature Transmitter using Emphasis at SIL 3 and 2 respectively
- Templates, databases and other harmonised approaches to the safety justification of embedded digital devices.
This paper describes work funded by Energiforsk to consider the feasibility of using harmonised component level safety demonstration and, in particular, on using aspects of the UK approach to licensing and qualification of smart devices in Finland.
- Justification of commercial industrial instrumentation and control equipment for nuclear power plant applications.
This paper discusses work done by the authors to develop an IAEA Nuclear Energy Series report to provide guidance on what would constitute an adequate justification process for a COTS device to be installed in a Nuclear power plant.
