In a written reply to a question in the Lok Sabha Union Minister of State (Independent Charge) Science & Technology; MoS PMO, Personnel, Public Grievances, Pensions, Atomic Energy and Space, Dr Jitendra Singh said, nuclear power is considered as one of the most promising clean energy options for power generation. There is a thrust world over for a strategy to use nuclear power that could reduce reliance on fossil fuels over the coming years.

In order to move away from fossil fuel consumption, SMRs can be installed and operated for repurposing the aging fossil fuel-based power plants.

China successfully powered up its “artificial sun” nuclear fusion reactor for the first time, state media reported on Friday, marking a great advance in the country’s nuclear power research capabilities.

The HL-2M Tokamak reactor is China’s largest and most advanced nuclear fusion experimental research device, and scientists hope that the device can potentially unlock a powerful clean energy source.

It uses a powerful magnetic field to fuse hot plasma and can reach temperatures of over 150 million degrees Celsius, according to the People’s Daily — approximately ten times hotter than the core of the sun.

Located in Sichuan province and completed late last year, the reactor is often called an “artificial sun” on account of the enormous heat and power it produces.

Chinese scientists have been working on developing smaller versions of the nuclear fusion reactor since 2006.

The development of nuclear fusion energy is not only a way to solve China’s strategic energy needs, but also has great significance for the future sustainable development of China’s energy and national economy,” said the People’s Daily

They plan to use the device in collaboration with scientists working on the International Thermonuclear Experimental Reactor –– the world’s largest nuclear fusion research project based in France, which is expected to be completed in 2025.

Nuclear fusion

Fusion is considered the Holy Grail of energy and is what powers our sun.

It merges atomic nuclei to create massive amounts of energy –– the opposite of the fission process used in atomic weapons and nuclear power plants, which splits them into fragments.

Unlike fission, fusion emits no greenhouse gases and carries less risk of accidents or the theft of atomic material.

But achieving fusion is both extremely difficult and prohibitively expensive, with the total cost of ITER estimated at $22.5 billion.
