Nuclear Safety Basics

Nuclear Safety Basics - Introduction to the goals and terminology of Nuclear Safety

  • Basics of nuclear power generation, inherent security, feedback
  • Comparison of Functional Safety (61508) and Nuclear Safety
  • Postulated initial events (PIE), design basis
  • Nuclear incidents, accidents - INES scale
  • Important reactor accidents and malfunctions:
    • Three Mile Island
    • Chernobyl
    • Fukushima
    • Serious incident at Paks in 2003
  • Regarding each nuclear accident:
    • What causes and events led to the accident?
    • How did the accident proceed and what were the consequences?
    • What and how could/should have been done differently to avoid the accident / reduce the consequences?
    • What lessons were learned from the accident and how did nuclear safety change, with particular regard to control systems?

Introduction to Model Driven System Engineering
Requirement Modeling
Magic Draw and licence

For the first assignment and all the lab session about modeling we will use Magic Draw.

You can download a preinstalled win x64 from the following url. Based on the feedback from you it seems to be not working for everybody so please use the licence and download the appropriate version from the website.

If you prefer to install it to any other system (iOS or Linux) use the following licence and download the appropriate version (the basic MagicDraw and the SysML extension) from here.

All downloadable content is password protected you will receive your password through the Neptun system!

First assignment: SysML modeling

Read the document carefully and create the required model along with its documentation.

Deadline: the 2nd of November 2014 23:59.

The upload site will be announced later via news and on this webpage

Structure Modeling slides
Requirement modeling laboratory

The model created during the laboratory session for requirement modeling.

Can be used as the starting point for the first phase of the second assignment.

Unzip the downloaded file!
