Yes, the accident became a disaster because it was so severe
It was estimated in 1980 that 30-40% of fatalities in survivable accidents are related to fire and its effects (FAA-ASF-300-1H).
Accident is one which occurs in a particular area and confined to the limits whereas disaster is an accident spreading to neighbouring areas and usually occurs in largescale.
The worst accident in history is considered to be the Chernobyl nuclear disaster that occurred in 1986 in Ukraine. The consequences of the accident included the release of a large amount of radioactive material into the environment, leading to widespread health issues, environmental contamination, and the displacement of thousands of people from their homes. The long-term effects of the disaster are still being felt today.
Nuclear power accidents are a disaster. The 1986 nuclear accident at the Chernobyl Nuclear Power Plant in Ukraine was a catastrophic accident.

I don't know that there is a technical definition of a nuclear disaster. There are two accidents that are commonly referred to as disasters. One is the well known Chernobyl disaster, and the other is the Kyshtym disaster, both of which were in the former USSR. The Windscale fire, Three Mile Island Accident, and other problems are referred to as accidents. There is an International Nuclear Event Scale, which rates events on a scale of 1 (least important) to 7 (most important). On this scale, the Chernobyl Disaster is rated at a 7, and the Kyshtym Disaster is rated at 6. Three Mile Island Accident is rated at 5, as is the Windscale Fire, and two other accidents. There is a link below to an article on the International Nuclear Event Scale.
The Canadian House of Commons caught fire in 1916. The exact cause of the fire was never resolved, but the Royal Commission investigating the accident ruled out enemy sabotage.
