(ZT) UPDATE AS OF 11:20 A.M. EDT, FRIDAY, MARCH 18:

Reactors 1, 2 and 3 at the Fukushima Daiichi nuclear power plant are in stable condition, with workers continuing to provide seawater cooling into the reactors. Containment integrity is believed to be intact on reactors 1, 2 and 3, and containment building pressures are elevated but are within design limits.

Site radiation doses have been decreasing since March 16. Radiation dose rates are fluctuating based on some of the relief operations, such as adding cooling water to the used fuel pools. Recent readings at the plant boundary are about 2 millirem per hour. Radiation dose rates at reactor 3 range between 2,500 and 5,000 millirem per hour.

The Japanese Self-Defense Force restarted cooling water spray into the Unit 3 reactor building and spent fuel pool at around 1 a.m. EDT on March 18. Plans are to spray 50 tons of water on the reactor 3 reactor building/spent fuel pool using seven fire-fighting trucks.

A diesel generator is supplying power to reactors 5 and 6. TEPCO is installing high voltage cables from a nearby transmission line to reactors 1 and 2. Once electricity supply is re-established, priority will be given to restoring power to reactor heat removal systems and cooling water pumps. Workers are seeking to install electrical cables to reactors 3 and 4 components in about two days.

Fukushima Daini

All four reactors at Fukushima Daini remain shut down with normal cooling being maintained using residual heat removal systems.

Daiichi Accident Rated 5 on International Event Scale

New International Nuclear and Radiological Event Scale (INES) ratings have been issued for the accident at the Fukushima Daiichi and Daini nuclear power plants, the International Atomic Energy Agency said.

Reactor core damage at the Daiichi reactors 2 and 3 caused by a loss of cooling function has resulted in a rating of 5 on the seven-point scale.

The loss of cooling and water supply functions in the spent fuel pool of reactor 4 was rated a 3, or "serious" incident. The loss of cooling functions in the reactors 1, 2 and 4 of the Fukushima Daini nuclear power plant has led to a rating of 3.

The rating for the Chernobyl accident was 7, or a "major accident" on the INES scale. The Three Mile Island accident was 5, or an "accident with wider consequences." For more information on INES, see the IAEA's website and this IAEA leaflet.

• 老金啊，我们都生活在有放射性物质中，至于是否达到损害身体程度，是很专业的问题，不可做文学类的夸张。 -大度读人- ♂ (0 bytes) () 03/19/2011 postreply 02:20:29

• 所以没事，去日本旅游去吧，哈哈。你一方面反对建造核电站，一面又说没事，一致点嘛 -金笔- ♂ (0 bytes) () 03/19/2011 postreply 10:37:04
