Frazer-Nash Consultancy helps with delivery of EDF's Continuous Emergency Monitoring System

News

EDF Energy is deploying a new fleet-wide nuclear plant telemetry system to assist responses to severe ‘beyond design basis’ events.

EDF’s Continuous Emergency Monitoring System (CEMS) has been developed to help power station operators deal with a wide scale emergency, which Charlie Hall, senior consultant at Frazer-Nash Consultancy and CEMS project technical lead, defined as an event assumed to have disrupted infrastructure on and off site, such as by widespread flooding.

Hall added that the project has been reporting to the Office for Nuclear Regulation (ONR), which issued a report in May 2015 that said: “The resilience of systems that provide key emergency data, which facilitates decision-making by emergency responding personnel, is being enhanced through the installation of CEMS.”

According to Frazer-Nash, the CEMS enables an operator to use a modular logging and telemetry system without relying on wider station infrastructure to support it.

The reactor-monitoring module connects to a secure satellite communications module and supplies data that can be accessed by operators on and around the site, plus staff at EDF’s Central Emergency Support Centre.
