University of Sheffield MSc Process Safety and Loss Prevention Safety in Nuclear Operations (Module CPE6014) Copyright CCGTS/SU/001 Issue 2 Page 1 of 16 01/04/2016 Managing Nuclear Risk Introduction Managing the Risk 1 It’s a Balancing Act! This module will help build your understanding of nuclear safety related issues and how we go about the business of managing risk, the content is not intended to develop detailed technical knowledge but to bring together a range of subject areas, some of which you may already have a knowledge of to develop an understanding of their interrelationships in terms of nuclear safety. The most important element to safe power generation is people. a healthy awareness of nuclear power and adopting a strong Nuclear Safety Culture is key to the future safety of our industry. Safe, Clean, Efficient Safe, Clean, Efficient; The challenge is to understand how this is achieved and how we ensure that nuclear safety is maintained. What contributes to managing the nuclear risk to acceptable levels? Do our neighbours’ agree? Does the wider society agree? What is Risk? W hat is Risk? What is Risk? “The chance that something adverse will happen” “The chance or possibility of danger, loss, injury etc.” Acceptable Risk What makes risk acceptable? What risks are you prepared to accept why? Risk acceptance is a balance between the benefits and the risk; No benefit no point taking a risk. Lots of benefit - take the risk Climb a mountain, dangerous sports, bet on a race, invest in the stock market. It’s all in the perception. Risk = Consequence x Frequency (or = Impact x Probability)

University of Sheffield MSc Process Safety and Loss Prevention Safety in Nuclear Operations (Module CPE6014) Copyright CCGTS/SU/001 Issue 2 Page 2 of 16 01/04/2016 Risk Plot Probability Impact Risk Plot Unacceptable Acceptable If we plot the level of Probability against Impact we can develop a model in which we plot a line which represents our acceptable level of risk based on Probability x Impact. This gives us a fixed measure. Of course if everyone plotted their own values of what would be acceptable and what is not then we would see that there is a ‘grey area’ around this line based on personal perception. Crossing the road What is the risk? Clearly we can not manage our nuclea r business against ‘grey areas’ it needs to be black and white - the requirements must be definitive. So we need to be able to put exact figures against risk. How do we measure risk? These figures need to be translated into risk of death / year so everything has the sane base line. What if you cross the road multiple times? What if the car drives faster (increasing the risk)? What if you stop in the middle of the road? Fundamental Hazard The uncontrolled release of radioactive material from the reactor core Not a bomb but a large release of fission products. We are worried about uncontrolled releases, we release some radioactivity all the time in gas, water, solid waste as monitored, authorised discharges. As the consequences of an uncontrolled

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
