Risk Management that Makes Risk ALARP in the age of IoT

Congratulating the start of the new international gathering ASRAM, I would like to point out in my talk that we are faced with various new risk management issues in these days, owing to the innovation represented by the internet of things (IoT).

To secure safety of nuclear reactors, it is required to reduce the public risk due to severe accidents as low as reasonably practicable (ALARP). While the pursuance of defense-in- depth have been regarded as an effective strategy for making risks of nuclear facilities ALARP, recently published INSAG 27 identifies the importance of accountable communication and interaction not only between plant operators and regulatory agencies but also among operators, regulators, the industry, stakeholders, citizen and international organizations or interaction among institutions in depth, not to mention the functioning of multilayered interaction driven by vibrant safety culture in each of them. Should we understand that the proposal is based on the recognition of the need for sociological pressure through these interactions to reduce risk due to epistemological errors or even "errors a sector doesn't recognize it doesn't recognize"? Yes, the proposal is surely based on the recognition of the importance of mutual communication among these sectors to cope with the fallibility of human-being or isolated autonomous organization and reminds me the statement that autonomy will be a key determinant for IoT risk.

(Biographical information)

Dr. Shunsuke Kondo joined the Department of Nuclear Engineering, School of Engineering, the University of Tokyo (UTokyo) as lecturer in 1970, after receiving BE, ME, and DE in nuclear engineering from the UTokyo in 1965, 1967 and 1970, respectively. Since then he dedicated to research and teaching in the area of nuclear engineering, promoting to Professor of Nuclear Engineering, School of Engineering of the UTokyo in 1984.

He retired from the UTokyo in 2004 when he was appointed to the post of Chairman of the Atomic Energy Commission, Cabinet Office by the Prime Minister. He retired from the position on March 2014.

He assumed the position of the President of the Nuclear Waste Management Organization of Japan on July 1st, 2014.

New Threats and New Design Bases

Since the very first nuclear power plant, the design basis accident(DBA), which is a large break loss of coolant accident (LB-LOCA), did not change. For that matter, Engineered Safety Features(ESFs) in a nuclear power plant (NPP) did not change much either. That is because current ESFs are basically for the current DBA, LB-LOCA. However, a series of core melt down accidents are happening. Therefore, we now know that a nuclear reactor core can go melt. In addition, there is still a big disparity between the public perception on the nuclear safety and nuclear engineers' safety. The current "nuclear energy" issue in Korea is "de-nuclearization" in the national energy mix. On the other hand, the "nuclear safety" issue is the question of "how many nuclear reactors could be built in one site." And what are the technical and/or legal bases for the judgement?

The current paper proposes that we need: 1) a new safety goal of zero release, 2) a severe accident as the new DBA and 3) additional ESFs for new DBA.

A risk look at energy development

The rainbow energies refer to a spectrum of seven kinds of energies, which all have strengths and weaknesses in terms of their efficiency, safety, reliability, environmental impact, reserves and economic value. Fossil fuels remain the world's dominant energy source, accounting for around 65%. Coal, the main culprit for greenhouse gas emissions, represents 43% of fossil fuels, and causes seven million deaths a year, according to the United Nations. At the same time, 30% of the world's population has no, or extremely limited, electricity resources, and yet this segment of the global community has to bear the consequences of any energy combinations adopted by the rest of the world.

Life has many risks: air pollution, auto accidents, terrorism, cybercrimes and system failures, among others. But the biggest risk today resides in energy and energy safety. The use of fossil fuels, and the climate change resulting from global warming, is affecting the future of our planet. Only a rational analysis of the relationship between energy and the environment will give us a clearer picture. No discussion of energies today can neglect the balance of the rainbow energies, including the nuclear energy as a key base-load power.

(Biographical information)

Way Kuo is President at City University of Hong Kong. He is a Member of the US National Academy of Engineering and Academia Sinica of Taiwan, and a Foreign Member of the Chinese Academy of Engineering and Russian Academy of Engineering.

Before joining CityU, he was part of the senior management team at Oak Ridge National Laboratory and Dean of Engineering at the University of Tennessee. He is renowned in design for the reliability of electronics systems and nuclear energy. His book Critical Reflections on Nuclear and Renewable Energy has been published in six languages in Taiwan, Hong Kong, mainland China, US, Japan, France and Russia.

He was the first foreign expert invited to discuss nuclear safety following the Fukushima incident. He argues that a holistic view of energy development is required, one that prioritises the production and use of reliable energy sources over that of polluting and volatile ones.
