TALK:FUKUSHIMA NUCLEAR ACCIDENT LOG MARCH 2011

Disputed sentences

These sentence are credibly questioned here. Of course, this can be restored. -- Tenmei ( talk) 20:41, 13 April 2011 (UTC) reply

March 11: With the loss of power from the grid and the damage to the generators, the plant has become "dark." A steam-driven turbine located in Unit 3 provide cooling to Units 1, 2 and 3.<:ref> http://www.oecd-nea.org/press/2011/NEWS-04.html Timeline for the Fukushima Dai-ichi nuclear power plant accident</ref> Later, reports indicate that only the generator for Unit 6 remained working in full operational capacity.

Radio nuclides exceeding the national regulatory standard were detected in milk produced in Fukushima prefecture and spinach from Ibaraki, Fukushima, Tochigi, and Gunma prefectures.
Evacuation radius	20 km from nuclear power station. People who live between 20 km to 30 km from the Fukushima I nuclear power station are to stay indoors.

Remarks	Immediate threat is damage to fuel in the spent fuel pool (SFP), which is outside the containment vessel. Spraying water onto the SFPs in units 3 and 4 is continuing. Reductions in ambient radiation around the plant suggest that this spraying has been effective in cooling down the SFPs. Seawater injection to the unit 2 fuel pool was conducted on 20 March. Work to recover grid power for the entire plant is in progress. So far power has been restored to the distribution switchboard for unit 2. Integrity checks of electrical equipment in unit 2 are in progress; these must be completed before the equipment can be energized. Grid power has also been partly restored to unit 5 (which continues to run from its emergency diesel generators). Radiological screening dairy and agricultural products, such as milk in Fukushima and spinach in Ibaraki prefectures, revealed levels of radioisotopes in excess of national regulatory standards. Shipment of these products has been restricted until further notice. Seawater sampled at the front coast of the station contained radioactive iodine-131, caesium-134 and caesium-137 levels exceeding the regulatory limit. Data collected by an IAEA team show radiation levels of 161 µSv/h in the town of Namie, Fukushima Prefecture, 20 km from the power plant. This level is 1,600 times higher than normal.^{[table 27]} The worldwide average background dose for a human being is about 2.4 mSv/year (0.27 µSv/h), which is 590 times less than 161 µSv/h.^{[table 28]}

Environmental effect (NPS border)	The Main Gate: 265.4 µSv/h at 15:00, Mar. 23. Radioactive nuclides exceeding the legal standard were detected in milk produced in Fukushima and Ibaraki prefectures and spinach and some other vegetables produced in Fukushima, Ibaraki and other prefectures. Also, radioactive iodine exceeding the standard set by Nuclear Safety Commission was detected in tap water in Fukushima prefecture. The level of the radioactivity detected is low enough not to do harm to the health of people who take those products or water for a limited time. Monitoring results of seawater sampled at coasts in the surrounding area of the station showed that radioactive iodine-131, caesium-134 and caesium-137, exceeding the regulatory limit were detected.
Evacuation radius	20 km from nuclear power station. People living between 20 km and 30 km from the station told to stay indoors.
INES (estimated by NISA)	Level 5	Level 5	Level 5	Level 3	-	-
Remarks	Immediate threat is damage of the fuel rods in the fuel pool outside the containment vessel. The operation for spraying water to the pool is continuing at units 3 and 4. Work to recover AC power for units 1 to 6 is in progress. External AC power has reached to units 2, 4, 5 and 6 and is now available in all the units. Integrity check of electric equipment is going on in each unit, which must be done before energizing them. Lighting has been recovered at unit 3's main control room. External AC power has replaced the emergency diesel generator in units 5 and 6.

Environmental effect (NPS border)	Radiation level: 1050 μSv/h at the south side of the office building, 163 μSv/h at the main gate, 75 μSv/h at the West gate, as of 15:00, 30 March. Radioactive material was detected from milk and agricultural products from Fukushima and neighboring prefectures. The government issues order to limit shipment (21 March) and intake (23 March) for some products from some areas. Radioiodine was detected from tap water sampled at some prefecture. Level in tap water temporally exceeds the provisional legal limit for infant consumption. Radioactive iodine, caesium, ruthenium, and tellurium were detected from seawater sample collected in the sea surrounding the power station. Nuclear Safety Commission of Japan released prediction of radioactive material spread caused by the accident (24 March), based on the computer model SPEEDI (System for Prediction of Environmental Emergency Dose Information).^{[table 31]}^{[table 32]} Radiation higher than 1 Sv/h was measured at the surface of water accumulated in the tunnel for laying piping outside Unit 2 turbine building on 27 March. Plutonium was detected from the soil of the Fukushima I site on 28 March at very low levels.
Evacuation radius	20 km from Nuclear Power Station. People who live between 20 km to 30 km from Fukushima I should consider leaving.
INES (estimated by NISA)	Level 5	Level 5	Level 5	Level 3	-	-
Remarks	Progress of the work to recover injection function: Water circulation for the reactor pressure vessel by temporary pumps was switched from seawater to freshwater at Units 1, 2 and 3 on 26 March, due to concern about possible erosion. High radiation is making work to restore the functioning of the original pumps difficult. Removal of water containing high concentrations of radionuclides from the basements of buildings of units 1 to 3 was partly begun on 26 March but will take time to complete. Three workers were sent to the hospital after heavily exposure on 24 March and discharged on 28 March. Function of containing radioactive material: It is presumed that radioactive material inside the reactor vessel would have leaked outside the containment vessel at units 1, 2 and 3, based on the investigation of the water samples in the turbine building from 24 to 27 March. On 30 March, NISA said that air may be leaking from the reactor pressure vessels of units 2 and 3 because some of their data show the pressure in the vessels is low, but there is no indication of large cracks or holes in the vessels. Cooling the spent fuel pool: Steam rising intermittently from the reactor buildings of units 1, 2, 3 and 4 has been observed. Injecting and/or spraying water into the spent fuel pool has been conducted on and off since 17 March.

I've taken the removed text and archived it at User:Dtgriscom/Fukushima nuclear accident log, March 2011. Please review the latter page, move all useful text to the former page, and delete all irrelevant text. -- Dan Griscom ( talk) 11:23, 24 March 2013 (UTC) reply
