March 15, 2011 Remembered

March 15, 2011 was the day that Fukushima unit 3's reactor blew in the largest of the explosions that rocked the plant in March of 2011.

Unit 3's MOX fuel contained plutonium, a very toxic as well as radioactive element (e.g., see here).

Nuclear engineer Arnie Gundersen of Fairewinds has hypothesized that unit 3 experienced a "prompt criticality" in the spent fuel pool.

Although Gundersen's account has been disputed, there has been no compelling evidence (in my opinion) to rule out his interpretation and, more importantly, reactor fuel from Fukushima's explosions was detected worldwide regardless of the explosion form (e.g., see

One group of researchers using Cesium-134 as a marker, which has a short half-life, reported detecting Fukushima plutonium, in Lithuania:
G. Lujanienė , S. Byčenkienė, P.P. Povinec, M. Gera M. (27 December 2011) ‘Radionuclides from the Fukushima Accident in the Air Over Lithuania: Measurement and Modeling Approaches’, Journal of Environmental Radioactivity, 114, 71-80.

Given the intensity of the explosive damage and the volatility of the fuel, it can hardly be surprising that 7 years later Fukushima Daiichi continues to produce heat and radioactive emissions whose traces are visible on the webcams.

My bet is that Diablo Canyon nuclear power plant in California, situated on a fault and next to the Pacific Ocean, will be the next Fukushima.
