Shelling at the Kharkiv Nuclear Power Plant in Ukraine
The shelling at the Kharkiv nuclear research facility in Ukraine has forced staff to evacuate the site, but they have since returned and have restored power supplies to safety systems. The facility is used for research, medical applications, and the production of radioisotopes. Its inventory of radioactive material is low, and it has subcritical nuclear material. But this does not mean it is safe. Here's what you need to know.
Reactor lifetime extensions
There have been concerns about the long-term operation of nuclear power plants since the first units were built decades ago. Today, the majority of nuclear power plants are older than 30 years. Many nations are looking into long-term operations of their reactors to maintain safety. IAEA offers safety review services to power plants worldwide. In Ukraine, two-thirds of nuclear power reactors are over 30 years old.
In May 2002, the NRI was awarded a license to build the Khmel'nyts'kyi nuclear power plant. The license covered the construction and operation of a nuclear research reactor named WWR-M and spent fuel storage. According to the license, the reactor's lifetime was due to end 31 December 2008. NRI submitted an application to the State Nuclear Regulatory Inspectorate of Ukraine requesting the reactor be extended until 31 December 2017.
The new construction of the fourth 750kV overhead line will help the plant produce more electricity. The plant's outdoor switchyard has been expanded, reducing transmission constraints and enabling 17 million kWh of additional electricity per day. The plant also underwent a lifetime extension of Units One and Two, which were due to retire in 2010 and 2011 respectively. The new extensions will keep the reactors operational until 2037.
Energoatom plans to build four new reactors and rebuild its VVER. In order to maintain the capacity of the South Ukraine NPP, the company partnered with Westinghouse Electric Sweden. In 2012, this fuel caused serious damage to the South Ukraine NPP, which forced the Ukrainian government to suspend the contract. After Russia annexed Crimea, the contract was revived.
The National Academy of Sciences of Ukraine has been entrusted with the scientific support of the nuclear energy sector. The Department of Nuclear Physics and Energy, which was established on Boris Paton's initiative, studied promising areas of nuclear energy development in Ukraine and provided appropriate proposals to the government. The Institute's research has produced promising results, including the development of titanium-based metal hydride materials for spent nuclear fuel containers. Additionally, the team is now exploring the production of nuclear-pure hafnium for use in neutron-absorbing elements.
Building on the existing nuclear infrastructure is an important option for Ukraine's energy future. The Ukrainian government should review existing reactors and plan expansion projects to increase the country's nuclear capacity. It should use expertise available to ensure the long-term sustainability of its nuclear power facilities. Ukraine's electricity needs are estimated at 8% from non-nuclear sources, primarily hydroelectric power. Investment in clean renewable sources of energy will increase the country's energy independence and help preserve the environment.
New dry storage facility for spent fuel
The new dry storage facility for spent fuel from the Khmelnytskyi nuclear power plant will be constructed in Ukraine. The CSFSF is undergoing licensing approval, and it will store spent fuel from PWR reactors. This facility will be operational by 2021. It will be constructed on a site near the Chernobyl nuclear disaster site. Ukraine has long hoped to store its nuclear fuel, but it faces many challenges.
Ukraine has three operating nuclear power plants and two more under construction. In March, the electricity grids of Ukraine and Moldova synchronized with the Continental European Grid. These plants store low-level waste and disused nuclear sources. The site in Kharkiv could store spent nuclear fuel from research reactors. Russian shelling in Ukraine reportedly destroyed an oncology centre near the plant. This damage compromised the safety and security of the high-level radiation sources. The lack of security arrangements likely contributed to the loss of nuclear materials.
A dry storage facility for spent fuel at Kharkiv's nuclear power plant is necessary to protect the reactor from further damage. The reactor is a subcritical assembly of 37 different nuclear fuel elements controlled by a linear electron accelerator. Ukraine has accused Russia of firing missiles from Grad launchers, which do not have precise targeting. However, the SNRIU says that radiation levels on the playground are safe.
The Zaporizhia nuclear complex is about 140 miles up the Dnieper River from the Black Sea. It has six reactors, which is more than any other location in the world. Three of them are not on the grid at this time. The open pools that are built at the plant's site are more susceptible to accidental damage than the other structures. This is a risk because the pool houses the most radioactive material.
Ukraine's nuclear power organization claims that Russian personnel were exposed to high levels of radiation while digging trenches on the site. The IAEA has dispatched personnel to the site to determine whether the workers were exposed to radiation. As of April, the IAEA has not confirmed or denied Ukraine's claim. Although the incident is unfortunate for all concerned, it is an important step toward peace in Ukraine.
There are some concerns regarding this new dry storage facility for spent fuel in Ukraine. Some local officials worry that Russian occupied Zaporizhzhia employees will take over the station's operations, even if it is not under Russian command. In addition to being illegal, the situation could also endanger the lives of Ukrainian workers. Currently, SNRIU personnel cannot directly supervise the station, as they work with Russians.
In the meantime, Ukraine is working to maintain a running inventory of fresh nuclear fuel, as well as reactor fuel cycle management. In addition to that, it has maintained a running inventory of spare parts and equipment. The government of Ukraine is in constant contact with Kyiv and other Ukrainian authorities to ensure the safety of the reactor. It is important to understand that Ukraine is a large consumer of electricity in Europe. This means that Ukraine's nuclear power plant safety and operation are at risk.
Russian military occupation of kharkiv nuclear power plant
During the Russian military occupation of Ukraine, a nuclear research institute in Kharkiv was shelled repeatedly. At the same time, the nuclear power station in Zaporizhzhia was attacked. Depending on the level of Russian military command and leadership, the military forces may take actions that could result in an accident. A nuclear accident would likely put the civilian population at risk of radiation exposure.
Video feeds from inside the plant show plumes of smoke and explosions. One building within the plant was set ablaze by a projectile, but is not related to the reactors. In a statement, Rafael Grossi, the head of the International Atomic Energy Agency, said there has been no release of radioactive material. However, despite the high level of security at the plant, the IAEA has put the situation at Zaporizhzhia in 24/7 response mode.
Ukrainian shift personnel have remained at the station despite the Russian military occupation. However, the operators have been put under tremendous duress and cannot provide direct safety oversight at the station. This has created a situation wherein SNRIU personnel are no longer able to provide direct safety oversight. As a result, these operators have been forced to work in extremely strained conditions and have no means of providing direct oversight of the nuclear power plant.
At this time, only one of the six reactors at the Chernobyl nuclear power plant is operating. The others are being put into a "safe" state and are "offline." According to Corkhill, this may have been a deliberate action by Russia. Russia could have attacked a nearby building to force the operators to shut down the plant. This, in turn, would lead to a leak of radioactive elements from the plant.
The US State Department says that the Russian military is responsible for most of the casualties. The US State Department has accused the Kremlin of blocking and throttling social media. Meanwhile, the Russian parliament is considering a bill to punish the publication of "unofficial" invasion reports. Although this is not a resolution to the crisis, this issue is of utmost importance to the Ukrainian people.
The occupied plant in Ukraine's Slavutych is located outside the exclusion zone around the Chernobyl nuclear power plant. The government of Ukraine has called for a ceasefire and urged the Russian troops to leave. The Ukrainian Foreign Minister has warned that if the Russian army didn't leave soon, the explosion would be ten times larger than Chernobyl. The Zaporizhzhia plant has six reactors and supplies more than a fifth of the country's electricity. The plant was taken by Russian troops, and the American Nuclear Society has backed this up.
The situation in Kharkiv is becoming increasingly dire. The Russian military occupation has led to a mass exodus of nearly 1.5 million people from the city. While a lot of media and government officials say the occupation is a temporary phase, there are no plans for the plant to be shut down permanently. Further, the situation in the country has become a global crisis. Meanwhile, the situation in Ukraine has impacted Russian nationals.
