Summary
-
The Zaporizhzhia power plant’s warning systems have stopped sending out information.
-
Ukraine previously stated that Chernobyl might discharge radioactive within 48 hours.
-
A state-owned nuclear power plant Energoatom stated that it is unable to cool spent nuclear fuel.
-
Spent gasoline is kept in metal canisters that are cooled in a big pool of water.
-
However, without energy, the water cannot be preserved at the proper temperatures.
-
Electricity is also utilised to power ventilators and for radiation monitoring.
-
Work to restore electricity has been hampered due to Russian control of the facility.
Nuclear safety monitors have lost communication with the seized Zaporizhzhia power facility, only hours after warning of a possible Chernobyl disaster.
The International Atomic Energy Agency (IAEA) reported that warning systems at Zaporizhzhia had ceased sending information in the days following Russian soldiers shelling the facility.
The statement came two weeks after the watchdog said that it had similarly lost contact with its systems that monitor radioactive material at the Chernobyl Nuclear Power Plant.
Rafael Grossi, president of the International Atomic Energy Agency, expressed worry over the “sudden suspension” of data transmissions to the watchdog’s Vienna headquarters.
He also stated that the cause of the interruption in updates was unknown, but the IAEA was still getting data from other nuclear sites in Ukraine, including three additional functioning nuclear power reactors.
Earlier, Ukraine warned that Chernobyl might leak radioactive within 48 hours and urged Russia to maintain an immediate truce to allow for repairs.
Energoatom, the country’s nuclear business, has previously warned that radioactive chemicals may be discharged if the site’s power loss continued, as it made cooling spent nuclear material impossible.
In the early days of the invasion, Russian soldiers captured the facility and cut the electricity.
Since then, repairs at the facility have proven impossible, and the plant is presently functioning on diesel-powered emergency backup generators.
The French government stated that it was in contact with the International Atomic Energy Agency (IAEA) and urged Russia to cooperate.
‘Reserve diesel generators have a 48-hour capacity to power the Chornobyl NPP,’ stated Ukraine’s Foreign Minister Dmytro Kuleba in a tweet.
‘After then, the cooling systems of the spent nuclear fuel storage facility would fail, potentially resulting in radiation leakage.’
Energoatom has stated that efforts to repair the link and restore electricity to the plant, which was the scene of the world’s worst nuclear catastrophe in 1996, has been hampered by fighting in the vicinity.
According to the business, there were around 20,000 spent fuel assemblies at Chernobyl that could not be maintained cold due to a power failure.
Their warming might result in the “emission of radioactive chemicals into the atmosphere.” The radioactive cloud might be spread by wind to other parts of Ukraine, Belarus, Russia, and Europe,’ according to the statement.
Without electricity, the plant’s ventilation systems would also be inoperable, exposing workers to deadly levels of radiation, according to the statement.
Russia seized control of the derelict nuclear facility on the first day of the invasion and has since taken control of Europe’s largest nuclear station, Zaporizhzhia.
Ukrenergo, the facility’s energy operator, has stated that electricity to the plant and its security systems has been completely shut off.
The plant ‘was entirely severed from the electricity grid,’ Ukrenergo said in a Facebook statement, adding that military actions meant ‘there is no chance of restoring the lines.’
Recent events have added to the region’s growing worry about safety and security.
‘These recent events contributed to the IAEA’s mounting worries about the safety, security, and safeguards implications of Ukraine’s war on the country’s nuclear facilities, including its four operational nuclear power reactors and the Chernobyl site,’ stated the IAEA.
‘The remote transmission of data from IAEA safeguards equipment situated at nuclear facilities throughout the world is a crucial component of our safeguards operation, both in Ukraine and worldwide,’ said IAEA Director General Rafael Grossi.
‘Such systems are implemented at various Ukrainian facilities, including all nuclear power plants, and allow us to monitor nuclear material and activity at these sites while our inspectors are not there.’
Staff at the Zaporizhzhia nuclear power station were seen on film last week appealing with Russian soldiers who were directing fire on the structure before taking it over.
The nuclear power facility, which generates around 20% of Ukraine’s electricity, was taken during a furious gun fight between Russian President Vladimir Putin’s soldiers and Ukrainian defenders, which ignited a fire in a six-story training building.
Fortunately, none of the site’s six reactors were physically damaged, and radiation levels remained normal, according to the United Nations’ nuclear monitoring organisation.
France announced on Wednesday that it is in contact with the International Atomic Energy Agency (IAEA) to examine the situation at Chernobyl.
‘We are attempting to explain these claims in collaboration with the International Atomic Energy Agency,’ said government spokesman Gabriel Attal, adding that France was requesting cooperation from Russia.
On Wednesday, a representative for Germany’s environment ministry stated that Germany was unaware of any radioactive leaks from Ukraine’s Chernobyl nuclear power facility.
During meetings over the weekend, French President Emmanuel Macron asked Russian President Vladimir Putin to assure the protection and security of Ukraine’s nuclear installations.
Later that day, the International Atomic Energy Agency (IAEA) stated that the power outage at Ukraine’s deactivated Chernobyl nuclear reactor had ‘no essential impact on safety.’
The United Nations nuclear watchdog in Vienna said Wednesday that Ukraine has informed them of the power outage, which violates a “key safety pillar on guaranteeing uninterrupted power supply.”
However, it stated on Twitter that ‘in this circumstance, the IAEA sees no major impact on safety.’
The IAEA stated that spent nuclear fuel at the site could be ‘effectively removed without the requirement for electrical support.’
Claire Corkhill, Professor of Nuclear Material Degradation at Sheffield University, told MailOnline that although the loss of electricity at Chernobyl was worrying, the spent nuclear fuel would not result in a nuclear’meltdown.’
‘With the energy supply to the Chernobyl facility out of commission, there are various areas of worry about the safety of the radioactive material held there,’ she added.
She stated that spent fuel from reactors one and three is kept cold in metal casings in a pond (that looks like a large swimming pool).
‘This material generates heat through radioactive decay and need regular cooling, which is accomplished by injecting fresh cool water into the ponds,’ she explained.
‘Without electricity, this water may slowly evaporate, potentially contaminating the building with low quantities of radioactive isotopes.’
The second issue, she claims, is the monitoring of radiation levels in reactor four, which detonated in 1996.
‘It is critical that radiation monitoring devices can continuously monitor the condition within reactor 4 so that we are aware of any potential grounds for worry regarding the exposed nuclear fuel that dwells there,’ Prof. Corkhill added.
‘Another major worry is the upkeep of the ventilation system in the New Safe Confinement facility,’ she added. The Chernobyl New Safe Confinement is the massive lid, often known as a sarcophagus, that was installed over reactor four in 2016.
‘This avoids further deterioration of Reactor 4 and the dangerous exposed nuclear fuel therein, and is critical to the site’s eventual decommissioning.’
‘If there is no electricity to this structure, we might see the entire 1.5 billion euro decommissioning programme fail to make the site safe once and for all.’
While Prof. Corkhill believes the loss of power would not result in widespread radiation leakage, she believes there will be’severe contamination within one of the spent fuel storage buildings.’
Prof. Corkhill’s research focuses on the long-term evolution of radioactive waste material in disposal settings, and she gives impartial advice to the UK government on radioactive waste management and disposal regulations.
She is leading a British team that is assisting in the massive clean-up effort at Japan’s crippled Fukushima nuclear power plant after producing material that replicates the most deadly radioactive debris still in the reactors.
Russia invaded Ukraine on February 24 and seized the derelict facility, the site of a 1986 tragedy that killed hundreds and sent radioactive radiation west across Europe.
Russian forces have been in control of the Chernobyl site since last week.
It was not immediately obvious what caused the damage to the electrical line that served it.
The UN atomic watchdog IAEA said on Tuesday that the plant was no longer sending data and expressed worry for workers working under Russian security.
According to the IAEA, the situation for the personnel was ‘worsening,’ citing the Ukrainian nuclear regulator.
The dismantled facility is located within an exclusion zone that also includes deactivated reactors and radioactive waste facilities.
The Chernobyl New Safe Confinement was built in 2016 to protect the reactor. It was meant to keep radioactive pollutants from being released for the next 100 years.
More than 2,000 people are still employed at the facility, which requires continual control to avoid another nuclear accident.
On Tuesday, IAEA Director General Rafael Grossi urged “the troops in effective control of the facility to promptly permit the safe rotation of staff there.”
He also reiterated his invitation to fly to Chernobyl or elsewhere to assure all stakeholders’ “commitment to the safety and security” of Ukraine’s power plants.
The IAEA stated in a statement yesterday that ‘the Director General indicated that remote data transmission from safeguards monitoring devices deployed at the Chernobyl NPP had been lost.’
Nuclear material and waste products produced by nuclear power stations are tracked by safeguards.
The IAEA has asked Russian authorities to release the 210 staff members who are being held hostage at Chernobyl to go, stating that while radiation levels in the region are relatively low, a’safe rotation’ of employees is required.
It comes after the Vienna-based UN organisation claimed on Sunday that Ukrainian officials reported an attack on a nuclear plant in Kharkiv, despite no increase in radiation levels at the site.
WHAT HAPPENED DURING THE CHERNOBYL NUCLEAR DISASTER IN 1986?
On April 26, 1986, a power station on Pripyat’s outskirts had a severe accident in which one of the reactors caught fire and exploded, releasing radioactive material into the surrounding area.
Over 160,000 people of the town and nearby regions were evacuated and are unable to return, leaving the former Soviet site a radioactive ghost town.
The exclusion zone, which encompasses a large portion of Ukraine and portions of neighbouring Belarus, will stay in place for generations until radiation levels decrease to acceptable levels.
Because of the considerable radiation that endures, the region is referred to as a “dead zone.”
The expansion of wildlife in the area, however, opposes this, and many say that the territory should be turned up to the animals that have gotten established in the area, resulting in the creation of a radioactive protected wildlife reserve.
