Thursday 26th April 1986 became a momentous date in modern history, when one of the reactors at
the Chernobyl nuclear power station in northern Ukraine, exploded. It was the most significant
reactor failure in the history of nuclear power, a Maximum Credible Accident (MCA).
The plant, just 20 km away from the town centre, was made up of four reactor units each
generating an output of 1,000 megawatts. The reactor in question exploded due to operational
errors and inadequate safety measures and the meltdown was directly linked to routine testing
on the reactor unit’s turbine generators. The test required reactor activity and the thermal
reactor output to be run down to a lower level. During the procedure, however, the reactor
plummeted to an unexpectedly low and unstable level of activity. At this point, it should have
been shut down; as the operators chose to continue with the test, the events subsequently
proved to be catastrophic.
More than 200 people died or were seriously injured by radiation exposure immediately after the
explosion. 161,000 people had to be evacuated from a 30 kilometre radius of the reactor and
25,000 square km of land were contaminated. As time went on millions of people suffered
radiation related health problems such as leukaemia and thyroid cancer and around 4,000 people
have died as a result of the long-term effects of the accident.
The Chernobyl disaster brought the ongoing discussion of the pros and cons of nuclear power to
the forefront of public attention. Critics saw the reactor failure as dramatic and alarming
evidence to support their anti-nuclear stance. Advocates of nuclear power insisted that the
fragile Chernobyl reactor was an outdated model, and that the plants of Western Europe and the
US demonstrated a vastly improved safety culture thanks to their more advanced technology.
These conflicting assessments of the accident have led to extensive research into nuclear
safety standards and the disposal of radioactive fuel elements. Today, the fundamental issues
surrounding the benefits and risks of nuclear energy and its future role in power generation
continue to be hotly debated.
