Belgium: Radiation accident more serious than expected
The accident occurred at the Institut des Radioéléments (IRE). The company produces radioisotopes for cancer treatment. On Friday, August 22, radioactive iodine-131 leaked from the plant.
According to the IRE, the leak was discovered the following Monday morning and operations were stopped. On Monday evening at 17:30 p.m., the operator informed the Belgian nuclear regulator FANC.
On Thursday morning, August 28, the nuclear regulator sent a team to Fleurus to take samples. On Thursday night, a warning was issued to the population. The authority recommended that people not eat fruit and vegetables from their gardens or dairy products. The accident was classified as level 3 on the seven-level INES scale.
The case raises questions. It is completely unclear why IRE did not contact the authorities until Monday evening. Contrary to initial statements, elevated radiation levels had apparently been measured in a ventilation shaft for two days.
What is even more incomprehensible is that the Belgian nuclear regulator only reacted days later. And why a spokesman for the authority initially said on the radio that there was no risk to the population.
At this point, IRE estimated that 45 gigabecquerels of iodine-131 had been released...

During maintenance work in an E.ON power grid switchgear on June 28, 2007, a short circuit in the 380 kilovolt transmission network caused a fault in the immediate vicinity of the Brunsbüttel nuclear power plant. The plant was then automatically disconnected from the power grid and very quickly shut down to the output of around 30 MW required for the plant's own needs by means of "load shedding". In order to avoid damage during the sharp reduction in output, a turbine emergency shutdown was triggered and, as a result, the plant's own needs were switched to the external network transformer. The turbine emergency shutdown was immediately followed by a reactor emergency shutdown. When the plant was restarted on July 1, the reactor water purification system was shut off twice. According to the operator, these were both due to incorrect operation by the staff. The barriers were classified in category “N” (Normal) according to the AtSMV and in level 0 (with no or little safety significance) according to the international accident assessment scale INES...

The second incident involved an uncontrolled "point of accumulation" where a critical mass of uranium could have accumulated and was discovered in the course of responding to the first incident. In other words, no protection systems were in place to prevent solution leakage from occurring at the bottom of an elevator shaft in the facility. The result of material accumulation in a confined space could be a criticality incident.

Of these, however, 3 got stuck in the top position, whereupon the reactor was shut down by injecting boric acid into the cooling circuit. An emergency shutdown was then simulated by retracting the remaining nine groups with a total of 54 control rods in order to check their function. It was found that a further 19 control rods failed in the same way (i.e. a total of 22 out of 60). The cause of the fault was a change in the design of the control rods by the manufacturer Gidropress. In the event of a simultaneous loss of coolant (e.g. due to the rupture of the supply line), its failure could have led to overheating and melting of the reactor core.

In April 2005, a leak was discovered in Sellafield, through which around 83.000 liters of radioactive liquid, consisting of nitric acid, uranium and plutonium, escaped unnoticed for months. It is the most serious incident at a nuclear facility in Great Britain since 1992. The public was only informed weeks later, the first press reports appeared on May 9, 2005. The "Independent on Sunday" later reported that the pipe had been leaking since August 2004, but this was not discovered until April 19, 2005.
The British nuclear company BNG (British Nuclear Group), which is responsible for the decommissioning of the Sellafield reactors, was fined on 16 October 2006 for negligence to pay £500.000 (around 750.000 euros) for the incident. The cost of this event is estimated at $76 million.
Since the late 1940's and Windscale/Sellafield's inception, approximately 20 incidents of greater or lesser severity involving the release of radioactivity have been reported. Up until the mid-1980s, large quantities of the nuclear waste generated in day-to-day operations were discharged in liquid form via a pipeline into the Irish Sea.

On the night of November 3rd to 4th, 2004, an accident occurred due to a turbine malfunction, which caused the Balakovo-2 reactor to be automatically shut down. The reactor is said to have suffered no damage. However, conflicting reports caused great concern among the population: "Hundreds of residents fled that day out of fear of radioactive contamination of the surrounding area. Shop owners closed their shops, and pharmacies were out of iodine products to prevent health damage caused by radioactive radiation." The reactor was restarted a few days later...

On November 4, 2004, an accident occurred at the nuclear power plant, which caused great concern among the population in the town and the surrounding area, and some even panicked. Eyewitnesses and news agencies reported that numerous frightened residents stocked up on iodine-based radiation antidotes in pharmacies. Universities in Samara, 300 kilometers to the northeast, were closed. Shops in the city advised their employees to stay at home. The environmental organization Greenpeace in Russia feared a leak. The incident brought back memories of the Chernobyl nuclear disaster in April 1986 in Ukraine (then part of the Soviet Union).
Ultimately, according to the operator Energoatom, the incident at the power plant was only a minor malfunction. There were no increased radioactive emissions and a danger could be ruled out, the Russian nuclear agency said...

Tihange Nuclear Power Plant
On November 22, 2002, an incident occurred in Unit 2 (INES 2). The reactor - which was shut down at the time and no longer critical - was still producing decay heat, which was dissipated by circulating coolant in the primary circuit, as in power operation. During a test, a safety valve on the pressurizer was opened by mistake, causing the pressure in the primary circuit to drop very quickly from 155 bar to 85 bar. The high pressure in the primary circuit during operation means that the water does not boil, even at high temperatures, but remains liquid. If the pressure drops, the boiling point of the water also drops. The decay heat of the fuel elements can then no longer be removed, and there is a risk of a core meltdown. In this specific case, due to the rapid drop in pressure, several safety systems were activated, which pumped water into the primary circuit and thus continued to cool the fuel elements. The pressure relief valve that had been opened by mistake was closed again after three minutes...

On December 14, 2001, another hydrogen explosion occurred, destroying a cooling line and endangering reactor pressure and containment vessels. Since the operator only reported the incident three days later, "the Federal Environment Ministry expressed doubts about the reliability of the operator" - a threat to withdraw the operating license." The safety team refused to shut down the reactor for an inspection and downplayed the damage for two months. Vattenfall stuck to its cover-up tactics and, in order to reassure the population, set up a "commission of experts" made up of nuclear power supporters. The Schleswig-Holstein nuclear regulator created a detailed list with several hundred defects, but it was not allowed to be published due to legal resistance from Vattenfall. The report was also not handed over to German Environmental Aid.
The nuclear-critical doctors' organization IPPNW accused Vattenfall of not responding adequately with retrofitting and safety measures to the hydrogen explosions in the Brunsbüttel and Krümmel nuclear power plants (Schleswig-Holstein), and of the Schleswig-Holstein state government of lying to parliament. The company and the state government rejected the allegations.

Serious incident at the Brunsbüttel NPP. 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 could 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, despite a violent 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.

Nuclear submarine. Sank after one of its own torpedoes exploded on board. Mostly raised and scrapped in 2001. The entire crew perished.
Kursk (submarine)
The Kursk, K-141, was a Russian nuclear submarine of Project 1990A (NATO code Oscar II class) built in 1991/949 and equipped with cruise missiles.
When it sank in the Barents Sea in 2000 as a result of an explosion presumably caused by a technical defect, the Russian military initially claimed that the Kursk had been rammed by a US submarine. The Russian Navy did not have a special rescue submarine that had rescue locks or robotic arms compatible with the Kursk, but only diving capsules. The hesitant Russian information policy, the initially unsuccessful rescue attempts by the poorly equipped Russian Navy to open the exit hatch with the help of Norwegian divers, and the skepticism of Russian naval officers as to whether it was still possible to open the allegedly damaged exit hatch, led to a serious delay and to the very late acceptance of foreign offers of help.
After time-consuming failed attempts, Norwegian divers, now operating from their own dive platform, managed to open the inner hatch three days after their arrival and more than a week after the explosion. They had to realize that there could be no survivors because all sections were already flooded. However, Norwegian officer Erland Raanes testified that, contrary to claims by Russian naval officers, no damage was found to the exit hatch. The Russian government then asked the Norwegian government to carry out the recovery of the bodies.
It later emerged that around 23 crew members had survived and managed to escape to the rearmost section, where the emergency exit hatches were. A fallen CO2 filter that came into contact with water or oil caused a chemical reaction that led to a fire. This consumed the remaining oxygen in the air and the men suffocated.

Salvage
After the use of diving robots, divers began in July 2001 to mark the places on the wreck where holes were to be drilled for the ropes to lift the wreck. The ship was raised by the Dutch companies Mammoet and Smit Internationale on October 8, 2001. Previously, the bow with the torpedo section had been separated from the rest of the ship underwater. The wire saw used for this purpose was manufactured by a Krefeld company. This wire saw consisted of sleeves coated with JG-DUR hard metal. With the help of the Giant-4 pontoon, the deep-sea tug Singapore towed the Kursk to the port of Roslyakovo (♁69° 4′ N, 33° 12′ E). There it was brought to the floating dock PD-50 and scrapped. The Kursk is the only one of the five sunken Soviet-built nuclear submarines that was raised.
