Vizag Scientist Offers Nuclear Reactor Crack Solution
A scientist named N Kalidas from Visakhapatnam has found a way to make nuclear reactors safer.
He discovered that mixing a special material called fly ash with concrete can make it stronger and last longer when exposed to radiation.
This is important because nuclear reactors can develop cracks over time due to radiation.
Kalidas and his team have been working on this for 35 years.
They shared their findings with the government, and now a big research center called BARC is going to help make this idea a reality.
If this works, it could make nuclear reactors much safer and last longer, which is great for everyone's safety.
N Kalidas from INSWAREB claims to have a solution to prevent cracks in nuclear reactor concrete structures.
Research shows that radiation transforms crystalline materials in concrete, leading to cracks.
INSWAREB's 35-year research on fly ash suggests that mixing it with cement increases concrete strength and durability.
The government has entrusted the Bhabha Atomic Research Centre (BARC) to further develop this technology.
The proposed nano-concrete technology aims to block radiation and extend the lifespan of reactor structures.
