A Wall Street Journal report -after interviews with former TEPCO engineers and executives- throws more light on the failure of power and cooling at certain reactors in Fukushima Daiichi that led to the nuclear meltdown. The difference not grasped at the time turned out to be the critical difference between the reactors where electricity to cool the reactors worked and where the the electricity failed. Of the 10 nuclear reactors at Fukushima, only the 4 with the earlier Mark 1 design failed. These reactors were the earliest reactors installed by G.E. beginning in the 1970's. The Mark 1 reactors were serviced by an American engineering firm called Ebasco. Ebasco designed the reactor buildings really small so that they would be compact and economical. Because of the small size of the reactor buildings the generators providing the electricity supplies to the Mark 1 reactors could not be installed inside the reactor buildings made of fortified concrete and were installed in buildings outside lacking similiar protection. These outhoused generator buildings could not withstand the tsunami, resulting in the loss of power and cooling for these reactors, and leading eventually to the meltdown. The reactors with the Mark II and later designs were installed along with the generators in the same fortified concrete buildings, and these survived the tsunami without disruption in power supplies and cooling. This critical difference was noted by older TEPCO executives who were intervewed, but nothing was done about this because of the added cost of making the major modifications that would be needed. The regulatory system also failed to catch the problems with the original blueprints and design for housing the reactors and generators for cooling reactors. In 2001 the original 30 year operating permit for the Fukushima Daiichi nuclear reactor was renewed, and again in 2011 for another ten year period. Japan's Nuclear and Industrial Safety Agency is part of the industry ministry, and not kept separate and independent from the nuclear industry, a structural flaw. The ministry considered its job to be promoting nuclear power, and increasing nuclear power from 30% in 2010 to 50% of Japan's electricity output. One inspection official says fundamental design and construction of the reactors from a 30-40 year old design were never looked at in safety reviews by regulators approving the extensions. He even goes to the point of saying that the reviews focussed on things like pipes and fittings, missing entirely the safety of the outhouse buildings housing the generators. One of the top TEPCO engineers says this difference stood out like a sore thumb when did a walk through during inspections. He failed to get the support from fellow engineers and Tepco executives for changes that would add to the cost....

Krugman points out the risks for the U.S. economy as the U.S. loses export competitiveness with the euro reaching parity with the dollar. The huge shift from $1.50 to the dollar at one point to parity gives Europe a sudden strong boost. Europe needs the boost to escape a deflationary trap, and there is little that can be done for capital flows and exchange rates, says Krugman. He points out that many Federal Reserve governors were clueless of the impact this could have on U.S. growth, sanguinely assuming the U.S. would boost growth in 2015. Better says Krugman for the Fed to be very careful about raising rates at a time when wage growth is sluggish, and inflation low.

European Union and at its heart Germany cut oil and gas use by 25% over a short period. The WSJ looks at one company that makes agricultural machinery such as harvester combines in Germany, and how it did this. The lesson from this experience- long dependent on cheap oil and gas supplies from Russia Germany was not expected to bounce back and cut its use sharply, when prices of Russian gas increased 20 fold. Not only did this German company slash gas use by 30% by making technical changes in how the machinery operated, and by using oil pipes, storing LNG from other countries such as Britain and Norway.  A 6% decline in sales to eastern and central Europe was offset by a 35% growth in sales in the US. By pivoting to the US German manufacturers have increased sales. The US has also become a major supplier of LNG to Europe. This makes it possible for Germany to conduct its own policies free of the kind of influence Russia exerted on Europe. So what does the CEO of German company Claas say about this experience- he says the export model is robust but in a different form with the US Europe's and Germany's biggest partner. The lesson of the past few years says CEO Bock- "Don't be dependent on one country." Not Russia, and not China. ...

Medvedev appears to have little role in setting policy in Russia, even though he has presented a different view of liberal groups and showed interest in pluralistic democracy and free expression of opinion. Putin has expressed a very different view about liberal groups, as representing foreign interests in Russia. The media remains tightly controlled in Russia, and elections are determined in the Putin way. A mayor picked by Putin won the Sochi elections even without campaigning, as many opposition candidates were disqualified or discredited before the campaign. He won with 77% of the vote. In this way elections take place in Russia but are conducted in a way which makes it very difficult for the opposition parties, and keeps media television coverage heavily pro-government.

Under the coordinated action by central banks in the U.S., Canada, Japan, Switzerland and the ECB, the U.S. Federal Reserve lends dollars to the ECB, getting euros in return, and the ECB in turn provides European banks with the U.S. dollars. The European banks were facing a shortage of U.S. dollars in November 2011. Money market funds in the U.S. had pulled back from investing in eurozone bonds in the third quarter of 2011, adding to the shortage of dollars. This action eases liquidity concerns.
