Not very much has happened this weekend, below is the status of the reactors. The first numbers are from JAIF, April 10th 18:00<\/a> and the numbers within () is from NISA, April 7th 12:00<\/a>. If there is only one number given its from NISA and from the 7th of april.<\/p>\n

A new blog<\/a> has appeared, Info on\u00a0#FNPP1 and Irradiatio<\/a>n, that updates graphs of several relevant parameters. Very nicely done! I hope they will\u00a0continuously\u00a0be updated, very good resource to bookmark. I direct link to the parameter pictures in the table below(i.e click on water level (meter) and you will get directed to the water level graph on the FNPP1 blog).<\/p>\n

Pressure in the number 1 reactor pressure vessel is continuing to climb. It is now about one seventh of normal operating pressure. The containment pressure is also rising, due to the ongoing nitrogen injection<\/a>. Work proceeds<\/a> in moving the radioactive water from the turbine hall basements in order to be able to\u00a0access\u00a0pumps and other things located in the turbine halls that are\u00a0necessary\u00a0to get the internal core cooling working again. After they plugged the leak into the ocean through the cable pit water levels are rising in the tunnel connecting to the pit, so TEPCO is preparing to pump the water from the tunnel to the turbine condenser within the turbine building. Steel sheets and barriers<\/a> has been put up in the ocean to contain water from flowing freely from leaks into the ocean.<\/p>\n

IAEA as usually has written an excellent summary<\/a> of the status of the Fukushima plant.<\/p>\n

I have attached a drawing of the Oyster Creek reactor, it should be very similar to the Fukushima reactors. It shows more detail compared to earlier drawings. The control rod drive pipings sure looks like a candidate for the leakage out of the number 2 reactor!<\/p>\n
