List of reportable events in German nuclear facilities

from Wikipedia, the free encyclopedia
Overview of the German nuclear power plants

This list deals with reportable operational events in German nuclear facilities . Events that fall under INES ≤ 3 and are among the reportable operational events or incidents in Germany are classified here. The entries are primarily intended to show operational disruptions that directly or indirectly pose a risk to reactor safety, the environment or health. Since this decision is often difficult, the entries were also rated after their echo in the press. Entries such as fuel element change, revision, accidents at work etc. cannot be found here. There have been no incidents in Germany from INES category 4 (accident) and are included in the list of accidents in nuclear facilities worldwide.

List of events

date place event
June 23, 1942 Leipzig In the laboratory of the experimental physicist Prof. Robert Döpel , a so-called uranium machine exploded while the uranium powder used was burned. It was a nuclear test facility that was used in the Third Reich as part of the secret uranium project . Hydrogen was produced, just like in the run-up to a number of later nuclear accidents - right up to Fukushima 2011. Although the size of the fire was relatively small, the extinguishing work by the fire police took two days. The emergency services did not wear respiratory masks, which meant they inhaled radioactive material. However, nothing is known about the health consequences, as the documents were destroyed in the war.
7th December 1975 Greifswald When an electrician at the Greifswald nuclear power plant wanted to show an apprentice how to bypass electrical circuits, he triggered a short circuit on the primary side of the block transformer in Block 1. The resulting arc caused a cable fire. The fire in the main cable duct destroyed the power supply and the control lines of 5 main coolant pumps (6 are in operation for one block). A core meltdown could have threatened, as reactor 1 could no longer be properly cooled. However, the fire was quickly brought under control by the company fire brigade and the power supply to the pumps was temporarily restored. The case was only made public on television after the fall of the Wall in 1989. Just a few hours after the incident, Soviet authorities informed the IAEA, which later classified it in INES 3 (precursor to an accident, here a “station blackout” meltdown scenario).
January 12, 1977 Gundremmingen nuclear power plant , Gundremmingen In cold and damp weather, short circuits occurred on two current-carrying high-voltage lines. The resulting quick shutdown led to control errors. After about ten minutes, the radioactive water in the reactor building of Block A was about three meters high and the temperature had risen to around 80 ° C. At first it was said that the reactor would be able to go back into operation in a few weeks. After the incident, the operators assumed that Unit A would be brought back into operation quickly. However, due to the modernization of the control and safety technology required by politics and supervisory authorities, the operators later decided not to recommission Unit A ( category A or E) for economic and political reasons.
May 13, 1978 Jülich experimental reactor AVR , Jülich A water ingress accident in the Jülich test reactor AVR, in the course of which the operating team manipulated the reactor protection system in order to be able to continue operating the reactor for almost 4 days, was only assigned to the lowest category C at the time. The accident led to a high level of contamination of the soil and groundwater under the reactor with strontium -90 and tritium (see AVR accidents ). According to the assessment of an independent group of experts appointed by Forschungszentrum Jülich in 2011 , this incident should have been classified at least in the middle category B, if not in the highest category A (see AVR expert group ). Critics of the pebble bed reactor concept assume that the much too favorable classification of this event as insignificant from a safety point of view served to preserve the development opportunities of pebble bed reactors.
June 18, 1978 Brunsbuettel Only two years after commissioning, two tons of radioactive steam leaked into the machine building through a torn off of a blind nozzle and subsequently into the open air through roof flaps. Nevertheless, the reactor continued to run for over two hours. The operating team had manipulated the automatic security system to keep the system connected to the grid. The Brunsbüttel nuclear power plant then stood still for more than two years. The incident was classified in the highest category A.
September 7, 1985 THTR-300 , Schmehausen , Hamm On September 7, 1985, the humidity sensors in the THTR-300 failed. In the event of a steam generator leak, they must trigger the quick shutdown. An undetected steam leak would lead to a rapid increase in reactivity. The event was assigned to the second highest reporting category B at the time.
May 4th 1986 THTR-300 , Schmehausen , Hamm In the THTR-300, radioactive aerosols emerged immediately after the passage of the radioactive cloud from Chernobyl . The investigations into aerosol emissions began only after a considerable delay. The cause of the emission is said to have been incorrect operation of the fuel element loading system. The aerosols are said to have been formed from deposits in the pipes of the charging system. The measurement records for emissions on May 4th were patchy. The regulator estimates that the approved maximum daily activity release may have been exceeded slightly, but this is not certain. As an upper limit, it specifies a value slightly above the maximum allowable emission totaled over 180 consecutive days. The reactor was shut down from June 3 to 13, 1986 by order of the authorities. In 2016, a former THTR employee spoke up and claimed that the aerosol emission was deliberate in order to blow dust-covered pipes free. It was assumed that this could not be proven because of the Chernobyl accident. The supervisory authority is investigating the allegations.
December 16, 1987 Biblis nuclear power plant , Biblis Incident in Block A of the Biblis NPP. When the reactor was started up, a valve that had to shut off a connection line to the reactor circuit, which was under 150 times atmospheric pressure, jammed and remained open. Only after 15 hours did the operating staff take the flashing warning lamp seriously; the control logic of the lamp was believed to be defective. The personnel did not shut down the reactor immediately, but opened a second, redundant safety valve to flush the jammed valve through and thus close it. The valve did not close and 107 liters of radioactive cooling water ran into the annulus . The safety valve closed seconds later. The incident came to the public only after a year through an article in an American journal (Nucleonic Weeks), but was reported by the operator to the authorities in good time, which in turn did not publish a press release. The incident was later classified as level 1 ( incident ) on the INES scale . After the incident, the manufacturers took remedial action: By retrofitting a pressure relief valve between the primary and secondary shut-off (i.e. the said valves) of these connection lines, a failure of the secondary shut-off and thus a bypass is prevented after the initial shut-off by means of pressure relief in the containment.
March 1994 Biblis In March 1994 the motor of a main coolant pump burned inside the containment in Biblis A because a short-circuit had occurred due to a chisel that was forgotten in the motor during maintenance work.
June 26, 2000 Grafenrheinfeld nuclear power plant , Grafenrheinfeld On June 26, 2000, an INES level 1 incident occurred at the Grafenrheinfeld nuclear power plant. Technical defects were found in five out of eight control valves that had been installed the year before.
July 5, 2000 Grafenrheinfeld nuclear power plant , Grafenrheinfeld In the Grafenrheinfeld nuclear power plant there was a fire in the engine of the main coolant pump, which is located in the immediate vicinity of the reactor pressure vessel. (Category N)
August 2001 Philippsburg nuclear power plant , Philippsburg At the Philippsburg nuclear power plant, the operating team overlooked the fact that the emergency cooling system did not meet the requirements of the operating manual when starting up unit 2. The emergency cooling system was sufficient to cool the cold and non-critical reactor. After restarting the reactor, the emergency cooling system was upgraded to the extent required by the limit values. However, the incident mentioned below occurred. The coolant, which is buffered in the flood tanks (emergency cooling system) of the nuclear power plant , fell below the permissible boron concentration. Three of the four existing containers were affected. Due to these events, the power plant manager and two board members of the operator EnBW lost their posts. (Category S and INES 2)
December 14, 2001 Brunsbüttel nuclear power plant , Brunsbüttel Serious incident. As it became known only a few months later, a hydrogen explosion had occurred in the immediate vicinity of the reactor pressure vessel . The supply line for cooling the reactor cover with a diameter of 100 mm was torn over a length of 2 to 3 meters. There was a risk that splinters would damage the containment by passing the splinterguard . The operator HEW tried to cover up the incident as far as possible. For example, it was only reported to the responsible ministry as "spontaneous seal leakage". Only after two months did the supervisory authorities manage to inspect the "leak" while the reactor was shut down, and the extent of the incident was discovered, amid a heated dispute with the operator. If the reactor had been shut down according to regulations immediately after the explosion, the operator would have had to buy additional electricity for several million euros at the beginning of winter.
February 8, 2004 Biblis nuclear power plant , Biblis A malfunction occurred at the Biblis nuclear power plant in which at least five of the power supply systems failed one after the other. During a storm, two high-voltage lines collided near the NPP and caused a short circuit. As a result, one main grid connection in the power plant failed, and the second shortly afterwards. The reserve connection did not work either. The emergency power supply of block A and the internal supply of block B then also failed. There was thus the risk that the security systems could no longer be supplied with energy. As a result of these events, the reactor was automatically shut down for safety reasons. The properly working emergency power diesel generators prevented worse. In the past, some of these four emergency power generators were not available several times during regularly recurring inspections, but one is sufficient to ensure that reactor safety is maintained. (Category E and N)
July 27, 2004 Neckarwestheim nuclear power plant , Neckarwestheim In the Neckarwestheim nuclear power plant there was an incident due to human error in which water from Block II contaminated with two mega becquerels got into the Neckar , despite countermeasures taken immediately . For the first time in Germany, the incident resulted in the operating company of a nuclear power plant ( EnBW ) having to pay a fine (€ 25,000). A manager was fired because he had been critical. (Category N and INES 1)
May 7, 2007 Philippsburg nuclear power plant On May 7th, 2007 the containment was not properly closed after an overhaul "because of an incorrectly switched limit switch". A valve was open on both sides of the security lock ( category E and INES 1 ).
July 2007 Unterweser nuclear power plant According to an E.ON report from July, one of four strings of the emergency and after-cooling system was "only available to a limited extent" during an unspecified time. In addition, repair work was periodically carried out on a second line. The remaining two strings (2 x 50%) would have provided sufficient cooling capacity for the limiting incident if required. The BMU then added and criticized this fact: The operator had been aware of the fault in the relevant line for over a year, but had not been rectified ( Category E and INES 1 )
June 28, 2007 Brunsbüttel nuclear power plant Smoldering fire. In addition, cracks would have formed on the cover plates. When the reactor was restarted, incorrect operation by the staff led to two shut-offs in the reactor water purification system on July 1st. A limit value has been exceeded when introducing water from the reactor into the condensation chamber. This limit value is intended to indicate a broken pipe in the system and then lead the system to shut off, but there was no broken pipe. Despite an express request from the reactor supervisory authority on July 2, the deputy plant manager initially denied this reportable event, and it was only officially reported on July 6 at noon. ( Category N )
June 28, 2007 Krümmel nuclear power plant
This article or section needs to be revised. More details should be given on the partly gross nonsense: "so that the reactor driver could only continue his work after opening the valves as a precaution (!) With a respirator (!!)". Please help to improve it , and then remove this flag.

u. a. Search warrant

On June 28, 2007, a fire on a transformer also started on the site of the NPP , which could be extinguished within a few hours. A short circuit for an unexplained cause is said to have ignited transformer oil . According to the authorities, there was no danger to the nuclear area of ​​the nuclear power plant . There were no injuries. The nuclear reactor was shut down by means of an emergency shutdown . The fire brigade was on site with around 80 emergency services to take measures against the fire. In the opinion of the Kiel Ministry of Social Affairs, which is responsible for nuclear supervision , the events in both Krümmel and Brunsbüttel are “definitely notifiable”. However, a spokesman for the operator of the Krümmel NPP, Vattenfall Europe , initially denied this for his power plant, as the event took place outside the reactor. The responsible ministry later admitted that the reactor was also affected secondarily. A too rapid pressure reduction of the reactor due to human error - the reactor driver misunderstood an instruction of his superior and opened two safety and relief valves by hand - and "unplanned failure of one of several reactor feedwater pumps " led to a "rapid pressure and level drop in the reactor pressure vessel " from 65 to 20 bar. "There was still enough water over the fuel rods at all times," said a ministry spokesman. The drop in water level and pressure could be compensated for by automatically connecting a further safety system. Vattenfall confirmed the events, but stated that the Ministry had been informed of the abnormalities "immediately after the fire and the emergency shutdown". The emergency shutdown also resulted in problems with the power plant's own power supply and with data backup. In addition, smoke gases from the fire got through the ventilation system into the control room, so that the reactor driver could only continue his work with a protective mask after opening the valves. Because of this series of breakdowns, the nuclear supervision of the Federal Environment Ministry intervened. On July 13, 2007, there were searches by the police because Vattenfall had repeatedly refused to question the reactor driver. A search warrant was issued after a report by the taz that there were allegedly injured people in the control room.

February 4, 2008 Krümmel nuclear power plant , Geesthacht On the morning of February 4, 2008, a smoldering fire occurred in a ventilation system in the power plant. This could be extinguished by the plant fire brigade within an hour with a fire extinguisher, external help was not necessary. The nuclear regulatory authority then dispatched an expert. However, radioactivity had never leaked because the accident site was outside the reactor building. This incident again aroused great interest in the media and was used by numerous environmental protection organizations as an opportunity to repeatedly question the Krümmel nuclear power plant and the safety of nuclear energy. At this time, the power plant had been idle since 2007.
June 6, 2008 Philippsburg nuclear power plant According to the Baden-Württemberg Ministry of the Environment, on the night of Friday, June 6th, 2008, a pressure drop in the containment of Block I was found that exceeded the permissible values. The container, which encloses important parts of the reactor, has a slight overpressure of 20 millibars during normal operation. According to the ministry, the pressure drop determined was 1 millibar per hour and was due to a leak. The leak occurred when the system was started up after the overhaul and immediately after the tank was flooded with nitrogen. On the international “INES” rating scale, it belongs to class 1 (“fault”).
4th July 2009 Krümmel nuclear power plant , Geesthacht Incident on July 4, 2009 . A reactor emergency shutdown occurred shortly after 12 noon . The cause was a malfunction in one of the two machine transformers , which resulted in undervoltage in two of the four power supply rails of the nuclear power plant. In addition, there were cooling problems when cleaning the reactor water and (with the additional fixation of a control rod ) there were indications of a defective fuel element ( INES 0). The rapid shutdown caused massive restrictions in the power grid in Hamburg. 1,500 of the city's 1,711 traffic lights failed, sometimes for several hours, and shopping centers were without light. Furthermore, several water pumps failed as a result of the malfunction, and when the pumps were restarted due to pressure surges, eleven water pipes burst, which meant that thousands of hamburgers were temporarily without a water supply. Schleswig-Holstein's Minister of Social Affairs, Gitta Trauernicht , who is responsible for nuclear supervision , then ordered the operator Vattenfall to perform a new reliability check. Furthermore, three days after the emergency shutdown, the company announced that a mandatory monitoring device , a so-called partial discharge measuring device, had not been installed on the affected transformer . Because of the incidents, the previous power plant manager was dismissed by Vattenfall. Shortly afterwards, a spokesman for Vattenfall admitted that fuel rod damage had also likely occurred inside the reactor. A few of the 80,000 fuel rods showed a defect.
