Fukushima, LENDIT and Cultural Relationships

CS Colloquium
When: Tuesday, 2/28/2012, 3:30 - 4:20 PM
Where: EP 122
Speaker: Akira Tokuhiro, Prof. of Mechanical Engineering, UIdaho

The Fukushima Dai-ichi and Dai-ni nuclear power station with 4 GE-BWRs units at one site and 2 BWR units respectively co-located on the north-central eastern coast of Japan withstood a 9.0 earthquake and a large-scale tsunami on March 11, 2011. All six units were constructed via a GE/Hitachi/Toshiba collaboration from 1967-1979. In spite of the immediate shut down of all units based on ground-level acceleration and decay heat cooling for some 30-45 minutes, loss-of-offsite-power by ingress of water into the diesel generators' pit, initiated loss-of-coolant accident; overall as a 'beyond design basis accident'. Further, all units faced unanticipated challenge of cooling spent fuel pools situated above the reactors in lightly-structured buildings. Several hydrogen explosions later and nearly 1 year since '3/11', the utility (TEPCO) and the Japanese Government are now facing a 20+-year cleanup effort. Evidence suggests that 3 reactor cores have partially-to-fully melted. The scale of the recovery, restoration and remediation effort will be very large. The Fukushima accident is perhaps an example of 'complex issues and challenges' for today's students. These grand challenges, such as climate change, sustaining the global economy, poverty, disease and social unrest will prevail for many years to come. The speaker contends that adoption of common metrics, length(L), energy(E), number (N), distribution (D), information (I) and time (time) [LENDIT] cuts across soft and hard science, engineering and computing domains, and as such offer an analytical `lingua Franca'. Perhaps the ultimate challenge along soft domains is predicting the unpredictable human being. The speaker will try to connect the dots along Fukushima, LENDIT and culture.
