Coast to Coast Hosts Arnie Gundersen: Updates on Fukushima Daiichi
Coast to Coast's John Wells hosts Arnie Gundersen of Fairewinds. First up, Arnie discusses the recent news that bluefin tuna caught off the coast of California were found to have radioactive contamination from last year's Fukushima accident. "They went fifteen for fifteen... that basically means that every tuna in the Pacific now is carrying cesium-134 and 137," he reported. Arnie expressed concern over the rush to get nuclear units in Japan running again before safety modifications are put into place. Even when you safely shut down a nuclear reactor, about 5% of the heat never goes away, he explained, adding that in the case of Fukushima 5% represents 150,000 horsepower worth of heat. If that heat isn't dealt with on a continual basis, a meltdown is possible, he noted. Arnie and John also talked about the astronomical amount of radiation in spent fuel rods, pointing out that the radiation in the fuel pool in Fukushima's Unit 4 is equal to all of the cesium exploded during the 700 above ground nuclear tests the United States did in the 60s and 70s. He suggested spent nuclear fuel rods be stored in heavily shielded dry casks.
