An emergency shutdown of a power unit occurred at a nuclear power plant in Finland

58

There are reports from Finland about an emergency situation at a nuclear power plant. We are talking about the incident at the Olkiluoto nuclear power plant, located on the shores of the Baltic Sea.


According to the latest information, one of the power units at the Finnish nuclear power plant was shut down. At the station today there are two types of electronic weapons: BWR and PWR. The company, which owns the nuclear facility, reports that now the station is "taking all the necessary actions to clarify the circumstances of the unit's emergency shutdown and taking technical measures."

According to the latest data, the second power unit of the nuclear power plant, which was put into operation in 1980, was turned off. Its capacity is about 710 MW.

The license for the operation of the 1st and 2nd power units of the Olkiluoto NPP is valid until 2038.

According to the latest data, the emergency situation at a nuclear power plant in a country neighboring Russia did not cause environmental problems. The personnel at the power units continue to work. At the same time, as reported, the station recorded a "slight" increase in the level of radiation. What in this case means the term "some" (how much it is in system units) is not reported.

            The EU is constantly trying to bend the Finns, but so far it is not very successful. The Finns, unlike the Balts, do not have euphoria from the EU, they look at things realistically.

These are all elements of a hybrid war that Europe has been waging against Russia for a long time. Despite the fact that Western politicians, straining their own throats, do not bother looking for the slightest justification for their own screeching. There is simply a command to yell at any reason without explaining the reasons, solely for the purpose of denigrating Russia's actions and economic resistance. Everything is clear, since the time of Ivan the Terrible ...

          Yes, you're right - I'm not a reactor specialist. For me, a reactor is a boiler, and the boiler can shut down (without protection) for various reasons: stopping the supply of fuel or air (the most gentle option is simply stopping combustion and vaporization), or destruction of the boiler. I hope for the first option, or for the protection actuation, as you wrote. But - I repeat - there is nothing in the news [yet] about stopping the reactor by the protection. hi

    Teollisuuden voima clarified that the emergency shutdown of the reactor was the result of an increase in the level of radiation inside the station. "The situation is stable, the station is safe," the message says.

    The company indicated that the “challenge now is to prepare the reactor for cold shutdown,” which in practice means cooling it down and maintaining it at normal temperature and normal pressure for a specified period.

    Well, yes, it's okay - the exercises, probably, with the cooling down of the reactor ... gee ...

    The coming year of 2004 was the first and the last year when all the work on the project went on as usual. The contractual company between TVO and AREVA was completed, without haste and fuss, a site previously chosen by Finnish customers for the construction of the power unit was prepared. Yes, it is worth saying a few words about the customer, since TVO in Finland is not just an ordinary energy company. 43% of TVO shares are owned by the state, of which 27% are owned by the state-owned company Fortum. The remaining 57% of the shares are owned by Finnish heavy industry companies. TVO not only operated the Olkiluoto nuclear power plant, but also owned both Swedish-made boiling water reactors, which produced 16% of all electricity generated in Finland. laughing

    Another amazing feature of the French-Finnish contract is the way in which the opportunities to contact subcontractors and with STUK were allocated. The supervising public authority could only contact the French-German consortium through TVO, and TVO had no right to contact subcontracting companies. Trifle? But this strange mediation led to a huge loss of time. The AREVA designers made the changes, transferred TVO, they transferred this STUK. STUK identified the shortcomings, passed on their wishes to TVO, they passed them on to AREVA. Long, dreary and devoid of the slightest sense. TVO sees that clearly defective equipment was delivered to the construction site, they contact AREVA, the French communicate with defective subcontractors ... Well, and so on. A trifle that over and over again led to a loss of time. Here's another quote from the same 2006 STUK report:

    “The constant use of excessive gaps between the welded edges during welding is a direct violation of the quality of work procedure and is absolutely unacceptable. Such situations would not be possible with a well-functioning quality control system. … The quality system applied by subcontractors and the supplier is insufficient. ”

    The supplier in this case was understood as a Franco-German consortium.

In the fall, there were rumors that the price would rise by another 500 million euros, and AREVA employees attributed this to higher prices for materials and an increase in salaries. As you can see, the French experienced a "rise in prices", like the Americans from Westinghouse, also at the time of the crisis, when prices for steel and concrete fell to the floor all over the world, when prices fell - for everyone and everywhere, except for AREVA in Olkiluoto ... laughing Have you hired Polish guest welders with ROSATOM too?

    In general, this is a jamb of this company, which admitted dozens of problems at nuclear power plants in France, that if London gets lost on the outskirts of a skiff, the EU loses the qualification level necessary to create reliable systems. Especially in Germany, it is noticeable from the best and most powerful reactors in the world to the mess with trances and black Arabs at nuclear facilities. In just 25 years! Lovers of camels and chopping off the heads of those accused of witchcraft, they also love to build ...

    Japanese police, in response to Prime Minister Keizo Obuchi's demands to conduct a "tough" investigation into JCO's activities, raided its Tokyo headquarters. The investigation already has the recognition of the company's management shedding light on the causes of the accident. Seven years ago, the plant adopted an internal instruction, which illegally, in violation of the rules for working with radioactive materials approved by state bodies, established a simplified technology for the manufacture of uranium fuel.

    Refusing automation, factory workers mixed uranium powder with nitric acid in ordinary stainless steel buckets using long-handled spoons and then manually, rather than using a pump, loaded the mixture into the tank of the production reactor. On September 30, they mistakenly poured eight times more uranium mixture into the reactor than expected, which led to an uncontrolled chain reaction. They managed to stop her by a miracle. The investigation also established that the workers who made the mistake knew practically nothing about the properties of uranium and did not have personal dosimeters.

    This was not the only breach of safety at the factory. According to eyewitnesses, the surveillance cameras located around the perimeter of the plant were always turned off. laughing

        .

        The volume was the same. But the initial material on September 30 was different - the enterprise started working with new raw materials, with a multiple degree of enrichment.
        With the use of standard automation, everything would have worked out - this was taken into account when developing the system. But with manual mixing, the workers simply did not understand what they were dealing with - and as usual they loaded the same volume into the reactor. Then they saw Cherenkov radiation - in a mixture of high concentration, the critical mass was exceeded, after which a chain reaction began.

    Newspaper "Kommersant" # 184 of 08.10.1999/XNUMX/XNUMX, An hour after the start of the search at the Tokyo headquarters of JCO, Prime Minister Keizo Obuchi, accompanied by the newly appointed head of the Agency for Science and Technology, Hirofumi Nakasone, departed from Tokyo to Tokaimura by helicopter. Visiting the ill-fated factory, the prime minister acknowledged the inadequacy of the government’s measures following the accident: "We could not imagine such an incident, and our system was inadequate."

    Obuchi promised to review the current laws regarding nuclear incidents, and, if necessary, amend them at the next session of parliament. Control over Japan's nuclear facilities will be tightened "so that the nation can feel safe again."

    JCO's fate is now being decided by the Science and Technology Agency. The issue of revoking her license is being considered, but the final decision will be made upon completion of the investigation. In addition, the authorities of Ibaraki Prefecture, which includes Tokaimura, intend to demand from JCO financial compensation, the amount of which is likely to lead the company to bankruptcy.

    Meanwhile, no one in Japan is in favor of closing the nuclear power plant. Now 51 nuclear reactors provide only one third of the country's energy needs, which are constantly growing. The construction of thermal or hydroelectric power plants in Japan is almost impossible due to the peculiarities of the Japanese landscape. Therefore, the Japanese nuclear program, which provides for the construction of another 2010 reactors by 20, will continue. A country that has mastered the technology of mixing nuclear fuel in a bucket to build storage of gaseous hydrogen is a trifle. laughing

    Since the Poles are in business, there is no need to worry about the fate of the project. They will also connect the neighbors on the bottom right, to accelerate the movement into the bright hydrogen future, and at the same time they will overpower them. laughing

    We often hear that the market is the backbone of modern society, but it is impossible to think with the spinal cord. Chernobyl and Fukushima prove that the atom and slovenliness are not "democratic" or "totalitarian". These people are no longer able to manage what they have created themselves.

    ... At the station today there are two types of electronic weapons: BWR and PWR ...


    The author of the article must be precise. To date, only 2 blocks BWR... PWR is not running, and it is not known when it will be started.

    Emergency shutdown is a common situation. Automation settings are paranoid. A little off. Why raise the noise. We need to get information on the merits.
    Here is a link from the industry site http://atominfo.ru/newsz02/a0718.htm. Judging by the article, the shutdown prevented further development of the incident. They will figure it out and run.

    And you might think if something like this happened at the NPP, then the media would have only one prada and nothing to the cream of truth? - All levels are measured at each meter with micro-roentgen accuracy ... Yeah, right now. The usual practice, routine expressions - everything is under control, we are working.
    And there is nothing dangerous in shutting down the unit, if it is not RBMK)))
