Technical Meeting on Evaluation and Dependability Assessment of Software for Safety Instrumentation and Control Systems at NPPs

Daejeon, Republic of Korea
 
23 - 26 September 2014
 

Background

TM_IandC_2014_thumbnail.pngThe purpose of the meeting was to serve as a forum for interested Member States to discuss commonly encountered difficulties and to share best practices or strategies used in the evaluation and dependability assessment of software used in instrumentation and control (I&C) systems important to safety at Nuclear Power Plants (NPPs), as well as to discuss the challenges and issues that need to be resolved in this area.

These difficulties were also discussed by the members of the Technical Working Group on Nuclear Power Plant Instrumentation and Control (TWG-NPPIC) at their 2013 meeting, where it was recommended that the IAEA initiate relevant activities to address these problems. In response, the IAEA is developing a new technical report entitled Evaluation and Dependability Assessment of Software for Safety Instrumentation and Control Systems at Nuclear Power Plants to provide guidance to Member States in this area.

An additional goal of this Technical Meeting, which was attended by 35 participants from 23 countries, was to disseminate information on the lessons learned through the work with the new IAEA technical report.

Objectives

TM_IandC_2014_thumbnail2.pngThe meeting had the following primary objectives:

• To provide an international forum for presentations and discussions on the subject of the meeting;
• To strengthen Member States’ capabilities for improved understanding of software dependability assessment;
• To disseminate the experience that has been captured while developing the new IAEA report entitled Evaluation and Dependability Assessment of Software for Safety Instrumentation and Control Systems at Nuclear Power Plants;
• To review the draft version of this report; and
• To support the IAEA in defining future activities in the field of software evaluation and dependability assessment.

Based on keynote speeches and participants’ presentations, it was observed that software dependability assessment is a relevant topic. A maturity of dependability assessment varies among countries. In this regard the IAEA technical report, as well as nuclear safety and security standards, provide an important guidance on how to properly address this topic in applications of digital I&C systems important to safety at nuclear power plants.    

The IAEA will further process the technical report and prepare its final draft for the next Consultancy Meeting, which is planned for March 2015.
