The Chernobyl disaster was a nuclear disaster that happened on April 26, 1986, at the Chernobyl Nuclear Power Plant’s No. 4 reactor in Pripyat in the Ukrainian Soviet Socialist Republic. In terms of both cost and lives, it is considered the deadliest nuclear disaster in history. It is one of only two nuclear energy accidents on the International Nuclear Event Scale graded seven—the most serious the other being the 2011 Fukushima nuclear disaster in Japan. More than 500,000 people were involved in the first emergency response, as well as later environmental cleaning, which cost an estimated 18 billion Soviet rubles ($68 billion in 2019 dollars adjusted for inflation).
The disaster occurred during a safety test on an RBMK-type nuclear reactor’s steam turbine. The power output unexpectedly decreased to near-zero during a scheduled reduction of reactor power in preparation for the test. The operators were unable to restore the test program’s specified power level, putting the reactor in an unstable state. Because the risk was not mentioned in the operating instructions, the operators went ahead and performed the test. The operators shut down the reactor after the test was completed. However, the reactor was on the verge of exploding due to a combination of operator error and significant design defects. An uncontrolled nuclear chain reaction began instead of shutting down, releasing massive amounts of energy.
The health impacts of Chernobyl on the general public are unknown. As of 2011, there had been an excess of 15 children thyroid cancer fatalities. According to a United Nations committee, the aftermath has resulted in less than 100 deaths to date. The linear no-threshold model, a controversial statistical model, makes determining the overall number of exposure-related deaths problematic. The entire death toll in the following decades is predicted by several models. The most reliable studies anticipate 4,000 deaths if only the three most contaminated former Soviet states are considered, and 9,000 to 16,000 deaths if the entire continent is considered. Following the accident, Pripyat was replaced with the new purpose built city of Slavutych.
In 1986, a nuclear power plant explosion in Chernobyl released a radioactive cloud that swept throughout most of the Soviet Union, including what is now Belarus, Ukraine, and the Russian Federation. The radiation affected nearly 8.4 million individuals in the three countries.
Only in 1990 did the Soviet government recognise the need for international help. In the same year, the United Nations General Assembly passed Resolution 45/190, which called for “international collaboration to address and alleviate the consequences of the Chernobyl nuclear power plant disaster.” That marked the beginning of the UN’s engagement in the Chernobyl clean up. To manage the Chernobyl cooperation, an Inter-Agency Task Force was formed. The UN established the Chernobyl Trust Fund in 1991, which is now managed by the Office for the Coordination of Humanitarian Affairs (OCHA). Since 1986, the United Nations and major non-governmental organisations (NGOs) have established more than 230 research and aid programmes in the areas of health, nuclear safety, rehabilitation, the environment, clean food production, and information.
The United Nations announced a change in Chernobyl strategy in 2002, with a new emphasis on long-term development. The UNDP and its regional offices in the three countries affected took the lead in putting the new strategy into action. In the impacted area, there is still a significant bit of work to be done. In 2009, the United Nations established the International Chernobyl Research and Information Network to support international, national, and public programmes aimed at the long-term development of these areas (ICRIN).
The United Nations General Assembly passed a resolution on December 8, 2016, declaring April 26 as International Chernobyl Disaster Remembrance Day. The General Assembly noted in its resolution that three decades after the disaster, there are still substantial long-term impacts and that the impacted communities and territories have ongoing needs. The General Assembly welcomes all Member States, UN agencies and other international organisations, as well as civil society, to participate in the commemoration.
The International Chernobyl Disaster Remembrance Day involves events held all around the world to raise awareness of the Chernobyl disaster’s ramifications and the dangers of nuclear energy in general.
Adi Roche, the founder of the non-profit Chernobyl Children International, spoke before the United Nations General Assembly, calling for a “renewal and recommitment to develop new ways, new initiatives to alleviate further the pain of the people in the devastated ravaged areas.”
The Chernobyl Disaster
The Chernobyl disaster is often regarded as the worst nuclear disaster in history. A reactor at the Chernobyl nuclear power station in today’s Ukraine exploded and caught fire on April 26, 1986, spewing unprecedented volumes of radioactive chemicals into the atmosphere.
Despite the fact that the disaster resulted in a relatively modest number of deaths, the catastrophe’s long-term consequences are significant and will continue to offer issues for many future generations. Numerous studies have proven the accident’s catastrophic health and environmental consequences, with a dramatic spike of thyroid cancer among children in Ukraine, Belarus, and Russia being just one of many heart-breaking cases.
With €2.2 billion funded by over 45 donor countries through funding managed by the European Bank for Reconstruction and Development, the erection of the new safe confinement over the old shelter was a major milestone reached in 2019. (EBRD). On July 10, 2019, the new secure confinement was handed over to the Ukrainian government. In terms of international cooperation, the project has one of the biggest scopes ever seen in the field of nuclear safety.
An integrated approach to sustainable development was developed to address the needs of the impacted regions and populations since the United Nations agencies moved their focus from humanitarian relief to prevention, recovery, remediation, and capacity development. To give development aid to Chernobyl-affected populations, the organisations, funds, and programmes have continued to work closely with the governments of Belarus, the Russian Federation, and Ukraine.
The International Chernobyl Disaster Remembrance Day is a worldwide commemoration, not a national holiday.
