Functional Safety: IEC 61513 – Instrumentation & Control for Systems Important to Safety in Nuclear Power Plants

This course is designed to provide an overview of the overall safety lifecycle of instrumentation and control systems important to safety at Nuclear Power Plants (NPPs), focusing on Nuclear Safety and Security.

The comprehensive agenda will help you understand the recommendations and limitations regarding the application of the IEC6 61513:2013 standard. This standard is recognised by the UK Office for Nuclear Regulation (ONR) as the key standard defining the requirements for instrumentation and control for systems important to safety at NPPs.

This course can also be delivered at a location and dates to suit your business needs.
