In last week’s op-ed piece (November 2), the chemical and biological hazard of Cesium, isotope 137 (Cs-137) was summarized. This week, we will look at how Cs-137 has been used to speculate on risk relative to the spent fuel pools at Fukushima Daiichi. Cs-137 is a...

A recent issue-revival of the radioactive water build-up at Fukushima Daiichi has brought fear of radioactive Cesium back to the forefront of the Japanese Press. The most recent analysis of the decontaminated waters at F. Daiichi reveals a Cesium concentration of 2.4...

Ninety-six percent of Japan’s nuclear power fleet is idled, and has been for more than a year. Much of the resulting electricity shortfall has been recovered by pulling old, unreliable “thermal” (mostly liquid natural gas-fueled) power plants out of mothballs. This...

The French Nuclear construction company Areva has announced a contract to back-fit Japan’s Pressurized Water Reactors (PWR) with hydrogen recombiners. The devices use passive catalytic oxidation to convert free hydrogen into water vapor inside the domed containment...

Today, Tepco has posted the results of the first water sample taken inside the unit #1 Primary Containment Vessel (PCV). We find results that come as more than a bit of a surprise. The interior water’s results have been compared to analyses of the water’s outside the...

This week, America’s prestigious Wall Street Journal posted a debate entitled “Should the World Increase Its Reliance on Nuclear Energy”. The principles in the debate are Mark Lynas, at Oxford’s School of Geography and the Environment, and Peter Bradford, adjunct...

Flexibility! That seems to be the key concept in the Japanese government’s final decision on its future energy policy. As a result, it seems the reports of the demise of nuclear energy in Japan are possibly premature….possibly. Recently, the Japanese Diet (congress)...

The Fukushima Updates have not been posting Tepco’s numbers on waste water treatment and storage this year. Why? Because the water levels in the four flooded building basements have stayed essentially the same for the entire period. Until the groundwater flows into...

For the past several weeks, America’s preeminent prophet of nuclear energy doom has been touring Japan. He says that Fukushima Daiichi is an accident still-in-progress, with the greatest potential for disaster being the spent fuel pool (SFP) of unit #4. (1) His...
