Yesterday the Swedish nuclear safety authority (SSM) published this on their web page:<br /><br />"Operations at the nuclear power plant in Oskarshamn, OKG, have problems in several areas. It shows the total lack of security."<br />"For a long time, the SSM criticized a number of problem areas at the nuclear power plant in Oskarshamn, OKG. But the company has not managed to overcome the problems."<br />"This means that we are forced to act."<br /><br />Of course the SSM is pro-nuke, and allows the nuke plant to continue operating:<br />"The decision SSM today has made also means that OKG must report its decision to restart Authority before the company can restart any of the reactors after a planned or unplanned stoppages."<br /><br />If I read this correctly, Oskarshamn could have a good chance to have an accident soon, as they'll try to not shut down the reactor even if problems occur.<br /><br />If your betting office offers bidding on nuclear accidents, bidding on Oskarshamn could be a good idea.<br /><br />Source: http://www.stralsakerhetsmyndigheten.se/Om-myndigheten/Aktuellt/Nyheter/OKG-under-sarskild-tillsyn/Atomfritznoreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-10916965500986900832012-12-21T15:40:14.766-08:002012-12-21T15:40:14.766-08:00Yes, and it is not even clear yet whether the sali...Yes, and it is not even clear yet whether the salinity already got high enough to do much damage.<br />According to the wording, it could even be a stoppage due to detection of mere trace quantities.<br /><br />So my delight about another potentially ruined NPP might have been premature.<br />The Swedish nuclear authority didn't yet post news about this on their web page.<br />Atomfritznoreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-63588342162479711422012-12-21T15:28:46.597-08:002012-12-21T15:28:46.597-08:00Salt water infiltration presumably is a gentle way...Salt water infiltration presumably is a gentle way of saying either the primary or the secondary cooling circuit is contaminated with salt water. Neither is a routine or easily corrected problem.<br />Most likely is contamination of the secondary loop, which feeds the steam turbines, because that is the leg that gets sea water cooling. As turbines require very pure water to avoid damage, it is unlikely that the problem was ignored for long, but it still means damage to the heat exchangers, a costly and difficult to fix component.<br />However, it is likely that the damaged component can be isolated from the circuit so that the system can be restored to operation, perhaps at reduced power, after the clean out of the contamination is completed.netudianthttps://www.blogger.com/profile/11726679291917155189noreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-23582492887486975722012-12-21T11:26:39.903-08:002012-12-21T11:26:39.903-08:00Wow, that's great news.

Big lumbering electric plants that fall apart, require electricity from coal/nat gas plants, breakdown often (When's the last time anyone's had a major problem at a coal-fired plant?), catastrophic consequences in case of true disaster, and a giant money hog. I don't want anyone to freeze to death. Being from the NE USA I understand freezing temps (Although it's been getting more mild here.), but what happens when those plants get shutdown due to damage for months, sometimes years? We have so much natural gas that fueling these plants should not be a problem, its CHEAP, and it's abundant. I'd rather have my state build extra FF plants, shut off the nukers, start investing in diverse "green" power plants, and overtime phase in a distributed power grid taking advantage of the renewables to lower FF usage on greater and greater levels till a minimum of FF plants are needed. A nice distributed grid of energy production does not need nuclear, in fact it squanders all monetary resources, and will become more sustainable and diverse and resilient over time. It's also cheaper. Pretty clear what we need to be investing in. No one would have to be left in the cold. We just have to convince these "econuts" that have reality twisted from the nuke propaganda. Have they had rolling blackouts from these shutdown plants? That's something to ponder here. <br /><br />Also, is this saying salt water got into the primary loop? That would be horrible. How can that even happen without large holes in the heat exchanger?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-32246987677558262742012-12-21T01:32:53.027-08:002012-12-21T01:32:53.027-08:00It is true it's very difficult to be rational ...It is true it's very difficult to be rational about such things!<br />The fact that no worker has died of radiation exposure yet is not surprising, given the now 26 years of knowledge since Tchernobyl:<br />http://www.unscear.org/docs/reports/2008/11-80076_Report_2008_Annex_D.pdf<br />Look at page 58 (V. Early health effects, figure VII, most exposed workers).<br />There are no short-term deaths below 2 Gy. However, the lowest range, which corresponds to the most affected Fukushima workers, does show some later deaths, attributable at least partly to the accident.<br />So even though the "these-50-will-die" hysteria is just hysteria indeed, and their dose is below the acute radiation syndrome level, these workers will definitely run a higher cancer risk in their later life.<br />Therefore, the minimum TEPCO & the government should do is guarantee them frequent health checkups to detect any early sign!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1765307840677473617.post-84181914474488782202012-12-21T00:31:54.395-08:002012-12-21T00:31:54.395-08:00Thanks for the link but it was hard for me to take...Thanks for the link but it was hard for me to take it or the links from the site seriously.
