This reactor will run on liquid thorium instead of uranium and is expected to be safer than the traditional reactors. As molten salt, when exposed to air, cools and solidifies quickly thus insulating the thorium, causing any potential leak to spill very little radiation into the environment compared to the leaks from traditional reactors.


About Thorium

Thorium is a radioactive, silvery metal which has been named after the Norse god of thunder Thor. It is more abundant and much cheaper than uranium, and it cannot be easily used to create nuclear weapons.

Molten-salt reactors

Molten-salt reactors, instead of using fuel rods, work by dissolving thorium into a liquid fluoride salt before sending this mixture into the reactor’s chamber at temperatures which is above 600 degrees Celsius.

India plans to create power islanding systems in several cities of the country to protect the critical infrastructures from potential attacks on the electricity grid of the nation.

Key Points


About Islanding systems

Islanding systems feature generation capacity and can automatically isolate from the main grid during an outage. For the new systems to be installed, the provinces need to submit proposals for setting up storage and generation capacities.

Reji Pillai, president of the India Smart Grid Forum, has recommended smart micro grids for isolating the smaller areas, such as industrial and commercial complexes, airports, shopping malls, hospitals, defense units and railway stations. This system would be connected to the main network and will automatically isolate during an outage. The micro grids would run on a mix of rooftop solar power and battery.

MS disturbs communication between the brain and the rest of the body. Under this condition, the myelin, a protective layer around the nerve fibres, get attacked by the immune system. It leads to inflammation and temporary lesions. As per WFN, Multiple sclerosis is a debilitating neurological disease that impacts a person’s life, with effects ranging from cognitive impairment to physical disability. The progression of MS can be slowed down by Disease-modifying treatments.


Symptoms of Multiple Sclerosis

Symptoms vary from person to person. Symptoms of this disease can also change on the basis of duration and severity of the disease. Some common symptoms include of this disease are fatigue, difficulty in walking, slurred speech, vision problems, weakness in limbs, lack of coordination and dizziness.

On 23rd July, 2021 the Indian Institute of Technology, Kanpur (IIT-K) launched technology innovation hub to find cyber security solutions for intrusion detection system, anti-drones technologies, cyber physical system and block-chain.



About the start ups

The start-ups which will be supported by IIT Kanpur’s C3iHub will bring in multiple innovations on cyber security space, developing services and products and focusing on designs which will be used to safeguard India’s critical infrastructure.

A large number of these start-ups will also be focusing on the creation of anti-drone technology which will be deployed to protect the critical infrastructures along the nation’s border. Last month, an IAF base in Jammu was attacked using drones which prompted the government to look into creating anti-drone technologies.
