Japan's Efforts to Ease Nuclear Crisis Hit Setback as Reactors Face Unexpected Rise in Pressure

FUKUSHIMA, Japan -- An unexpected rise in pressure inside a troubled reactor [#3] set back efforts to bring Japan's overheating, leaking nuclear complex under control Sunday...

The pressure increase meant plant operators may need to deliberately release radioactive steam...

...

But the buildup in pressure inside the vessel holding Unit 3's reactor renewed the danger, forcing officials to consider venting...

...

Nuclear safety officials said one of the options could release a cloud dense with iodine as well as the radioactive elements krypton and xenon.

No gases to be released from No. 3 reactor

The Tokyo Electric Power Company has decided against releasing gases from the overheating No. 3 reactor in an attempt to reduce pressure inside the containment vessel.

TEPCO officials in Fukushima said on Sunday afternoon that pressure within the reactor containment vessel has begun to stabilize, and gases don't need to be released for the time being.

They say they will closely monitor the situation.

The Nuclear and Industrial Safety Agency announced earlier on Sunday that pressure inside the vessel is rising despite efforts to cool the reactor by spraying seawater inside it.

The agency said the pressure must be reduced to protect the containment vessel, which holds radioactive materials inside in the event of an accident.

A release of gases could lead to radioactive substances being released into the environment.

Power company officials in Fukushima also say work to restore electricity to the Fukushima Daiichi nuclear plant by connecting the damaged reactors to external power sources is continuing.

Interesting how both news sources Fox and NHK give basically the same information but each has its own perspective and message.

Earlier report from NHK indicated they would need to release gases if pressure didn't stabilize. Two hours later the above report from NHK was issued.

The foreign news media is behind the Japanese news because of the time zone difference.

And the foreign news media tends to have more exploitative titles to their news articles.

The truth is that the rise is pressure has been happening on and off since the beginning of this saga. It is not "unexpected".

machine translation of the above story -

Unit 3 is building some pressure but they do not think they have to relieve that pressure with a gas release yet. They are monitoring the situation.

Unit 3, without immediate outgassing TEPCO

13:16 May 20

Pressure rises due to the reactor containment vessel containing Fukushima Daiichi Nuclear Power Station Unit 3, TEPCO plans to reduce the pressure of working gas discharged to the outside of the vessel that contains radioactive material had, Toukyoudenryoku Hukushima According to the office, all that pressure has stabilized, "currently No. 3 in a state does not require immediate release. will 見守Ritai pressure conditions carefully," he said, In the meantime, has revealed that you do not release.

The Unit 3 nuclear power plant Fukushima Daiichi Although continued work to inject water to cool the reactor, that increases pressure in the containment covering the reactor in the morning 20 It is confirmed that. Therefore, to prevent damage to the containment, releasing the gas containing radioactive material outside, and was considering lowering the pressure that you do, and depending on the office Hukuzima TEPCO, the pressure has stabilized With that said, "No. 3 in the current situation does not require immediate release. will 見守Ritai pressure conditions carefully," he said, meantime, has revealed that you do not release. According to the office Toukyoudenryoku Hukuzima currently supply restoration work being done at Fukushima Daiichi nuclear power plant has not been suspended, continued, is that it keeps.
