In March 1972, Stephen Hanauer, a technical advisor with the Atomic Energy Commission, met with Norman Rasmussen, a nuclear engineering professor at the Massachusetts Institute of Technology. The AEC had recruited Rasmussen to develop a report, The Reactor Safety Study (WASH-1400), to estimate the probabilities and consequences of a major nuclear power plant accident. With thousands of safety components in a modern reactor, the task was mind-boggling. Rasmussen proposed a novel approach based on more powerful computers, “fault tree” methodology, and an expanding body of operational data. By calculating and aggregating probabilities for innumerable failure chains of components, he believed he could develop a meaningful estimate of overall accident risk. WASH-1400 would be a first-of-its-kind probabilistic risk assessment (PRA).

The American Nuclear Society has selected a group of Black former students known as the Tennessee-85 to receive the inaugural Social Responsibility in the Nuclear Community Award. The 85 former students are receiving the honor in recognition of their bravery and leadership displayed in desegregating an Oak Ridge school in Tennessee in 1955. A co-recipient of the award is the Secretary of Energy for the leadership displayed by the Atomic Energy Commission (now the Department of Energy) in ordering the all-white Oak Ridge public schools to integrate that year. The award will be presented at the upcoming ANS Winter Meeting.

After decades of relinquishing its value and return on investment as “emission-free” electricity generation, segments of the nuclear industry are pursuing actions in several states to secure emission credits for avoiding greenhouse gas emissions. To harmonize electricity market stability and greenhouse gas emission reduction goals, states such as New York and New Jersey have enacted programs to award zero emission credits (ZECs) to nuclear plants for their emission-free output.

Dearly earned and too long forgone, air emission credits have been the economic birthright of the nuclear industry since the passage of the 1990 Clean Air Act (CAA) amendments, when emission control capability first became a tradable commodity. Yet it took until 2016 for ratepayers and shareholders to receive even a small fraction of this valuable return on investment.
