Alarm goes off at Oi nuclear plant, 1st trouble since restart decided

An alarm went off Tuesday night at the No. 3 reactor of the Oi nuclear power plant in Fukui Prefecture, indicating a minor problem, the plant operator and the government said Wednesday during preparations to reboot the reactor. 

It was the first sign of trouble since the government decided Saturday to restart the plant’s Nos. 3 and 4 units […]

Delayed disclosure at Ohi plant

Kansai Electric Power Company said on Wednesday that the alarm suggested the water level had fallen in a tank used to cool an electric power generator at its No.3 reactor.

The firm says workers who examined the tank found no leaks but that the water level was about 5 centimeters lower than usual.


the disclosure of Tuesday’s incident came about 13 hours after the alarm went off.


Nuclear and Industrial Safety Agency official Yasushi Morishita apologized at a news conference, saying his lapse in judgment caused the delayed disclosure.

(Update) Alarm Rings at Oi N-Reactor during Restart Work

An alarm rang at the idled No. 3 reactor of the Oi nuclear power plant in central Japan on Tuesday night, warning of falling water levels in a cooling water tank for the reactor’s power generator, the plant’s operator said Wednesday. 


The alarm went off at around 9:50 p.m. Tuesday (12:50 p.m. GMT), warning that the water level in the tank fell at least 10 centimeters from the standard level, according to Kansai Electric and the Nuclear and Industrial Safety Agency.


The alarm rang due to temporary changes in the water level, Kansai Electric officials said. Some more water will be injected into the tank just in case, the officials said.

    Finally, a truthful problem. We will need to keep an eye on that reactor. Looks like someone is spilling the beans. Tepco can not hide anymore, Some people actually have a conscience. Who knew?


    I can't believe they actually restarted that reactor. What a bunch of fools……..

      Has Oi actually been restarted? -"Alarm goes off at Oi nuclear plant, 1st trouble since restart decided"
      Kyodo News
      and – (Update) Alarm Rings at Oi N-Reactor during Restart Work
      Jiji Press

      Both suggest working toward restart, not actually restarted.
      Can I be right please?

  • dosdos dosdos

    Why did they choose a set of reactors that are sitting on an active fault line? They are worse than fools, they are idiots.

    Again, NISA withheld information from the public. Surprise, surprise…..

    If water leaked 10cm during restart it means there is a leak. With a leak comes an alarm which should have been announced to the public as it happened. 13 hours later is not within the bounds of nuclear reason. It only takes an instant to release clouds of death and cancer upon the population. Yet stupidity never changes. The idiot parade is in full march as nuclear agencies struggle to understand what the hell is really going on while keeping everything they can from the drooling masses.

    Here we go….showing how *transparency really works when the Nuclear and Industrial Safety Agency official Yasushi Morishita apologizes at a news conference, saying his LAPSE IN JUDGEMENT caused the delayed disclosure.

    So his judgement can NOT be counted on as he admitted. And shows the *excuses that we will continue to hear.

  • MaidenHeaven MaidenHeaven

    So maybe the Safety Agency official Yasushi Morishita needs to HEAR THIS:

    Reactor Head Failures
    The reactors at Oi are Westinghouse PWR reactors. 30 of this type of reactor worldwide have been found to have reactor head corrosion and cracking issues.

    Borated water is used in these reactors and this has caused issues of corrosion in reactor caps.

    CNIC also revealed that unit 3 at Oi could be at risk for significant damage in the case of a plane strike.

    Some basic understanding of how tsunamis are known to act raises serious concerns about the siting of Oi.

    NISA has discovered that the north hill near units 1 & 2 at Oi is at risk for a landslide.

    The general landslide risk inside the plant complex also raises concerns about damage or blockage of key areas, loss of offsite power and also the safety of any equipment staged at a higher location.

    Plant height risks exist at Oi.

    Read complete report & be sure to take a look at the PRE & Later work required…

    Japan putting all bets on new nuclear agency to deal with contentious issues

    Shoichi Kondo, DPJ leader in the lower house committee on nuclear regulations, is quoted by the Wall Street Journal as saying that the regulator could well be swayed by political considerations, since it will be headed by five commissioners appointed by parliament. “The political party in power can ultimately choose the members of the commission, and thus its policy direction,” Mr. Kondo told WSJ Japan Real Time.

    Should we plan an "I told you so" protest?

    Hi all,

    We protested the Ohi restart in Chicago on June 15th in solidarity with those protesting in Japan.

    I posted an account of it on my blog. If you don't have time to read it let me just say that the Japanese Consulate in Chicago would not accept our letter of protest. They would not allow a few people up to deliver them and they would not send anyone down to accept them.

    Also, to Joy who was at the protest. Please contact Nuclear Energy Information Service they want to keep you in the loop about upcoming events etc..

    Nukes are humanly impossible to tame. And they consume more energy than the electricity they generate during their entire life time. They are not an acceptable choice for meeting human electricity needs.
