Nuclear energy offers many benefits over other forms of energy, ranging from cost-effectiveness to low environmental impact.

However, the production of nuclear energy involves certain risks, and it can have disastrous consequences in the event of a meltdown or other accidents.

Here is a look at five of the most dangerous nuclear power plants in the world.

Kozloduy Nuclear Power Plant, Bulgaria

The Kozloduy nuclear power plant in Bulgaria consists of six Soviet-designed reactors, and the first four units do not have any containment structure. If a meltdown occurs, the radiation will spread across the country and the Balkans, and possibly to as far as Italy.

Another problem is that the reactors are not equipped with reliable emergency core cooling systems.

Despite upgrades funded by western countries, the cooling systems, as well as the fire protection systems and controls, fail to meet international safety standards.

Kola Nuclear Power Plant, Russia

The Kola nuclear plant is situated in Murmansk Oblast in the northwestern part of Russia, and it comprises four reactor units.

Three of its reactors have exceeded their 30-year design service lifespan, and they are considered dangerous and illegal. Additionally, the reactors have design and structural defects that are irreparable, and they can potentially contaminate a very large area.

The state and foreign organizations are constantly donating funds to improve the safety of the Kola nuclear plant, but their efforts are largely in vain.

Metsamor Nuclear Power Station, Armenia

Armenia's Metsamor nuclear power station is home to one of the few remaining first-generation water-moderated Soviet-designed reactors that were constructed without containment structures.

Its reactor is close to retirement age, and it is dangerous because of its design and location in a highly earthquake-prone region.

Fukushima Daiichi Nuclear Power Plant, Japan

Even before it was damaged by an earthquake and tsunami, the Fukushima Daiichi nuclear power plant was already regarded as one of the riskiest in the world.

The facility is situated on the Pacific Ring of Fire, and it was not properly maintained to meet safety standards. After disaster struck, it contaminated an area of about 4,500 square miles and forced more than 60,000 residents of the Fukushima prefecture to evacuate.

Cernavoda Nuclear Power Plant, Romania

The Cernavoda nuclear power plant has two reactors, which account for about 20 percent of Romania's power needs.

These reactors have been plagued with problems since they started operating, and they were temporarily shut down on a number of occasions. Also, the plant lies in an area that is relatively vulnerable to earthquakes.

The Potential Risks of Nuclear Power Plants

The main hazard that is associated with nuclear power plants is radiation.

Exposure to nuclear radiation can increase the risk of cancer and genetic diseases, undermine body function and even result in death. Nuclear plants also produce radioactive waste, which can have long-term negative effects on the environment.

Nuclear disasters can potentially cause great damage to human beings, animals, plants and the environment.

As such, governments, utility companies and other organizations should take adequate measures to minimize the risk of nuclear accidents.

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
