3. India To Build Nuclear Power Plants In "Fleet Mode" From 2023
Tags: Science and Technology
The Government of India plans to start construction of ten 'fleet mode' nuclear reactors over the next three years, with the first pour of concrete for a 700 MW atomic power station in Karnataka's Kaiga slated for 2023.
Under the fleet mode, a nuclear power plant is anticipated to be built over a period of five years from the first pour of concrete(FPC).
The first pour of concrete (FPC) marks the beginning of construction of nuclear power reactors from the pre-project stage which includes excavation activities at the project site.
The officials of the Department of Atomic Energy informed the Parliamentary panel on science and technology that the “ FPC of Kaiga units 5&6 is expected in 2023; FPC of Gorakhpur Haryana Anu Vidyut Praiyonjan units 3 & 4 and Mahi Banswara Rajasthan Atomic Power Projects units 1 to 4 is expected in 2024; and that of Chutka Madhya Pradesh Atomic Power Project units 1 & 2 in 2025”.
The Centre had approved construction of 10 indigenously developed pressurized heavy water reactors (PHWR) of 700 MW each in June 2017. The ten PHWRs will be built at a cost of Rs 1.05 lakh crore.
The PHWRs, which use natural uranium as fuel and heavy water as moderator, have emerged as the mainstay of India’s nuclear power programme.
India’s first pair of PHWRs of 220 MW each were set up at Rawatbhata in Rajasthan in the 1960s with Canadian support.
As many as 14 PHWRS of 220 MW each with standardized design and improved safety measures were built by India over the years. Indian engineers further improvised the design to increase the power generation capacity to 540 MWe, and two such reactors were made operational at Tarapur in Maharashtra.

9. 93% of Indian lives in high air pollution areas
Tags: Science and Technology
The United States based Health Effect Institute (HEI) in its Annual report “State of Global Air analysis for the year 2020” has found that around 93% of the Indian population lives in areas where the air pollution is seven times the World Health organisation (WHO) standards.
Major highlights of the report
93% of the Indian population is exposed to air containing at least 35µg/m3 concentration of PM2.5 (particulate matter of the size of 2.5 microns). According to the WHO standards, the upper annual limit for PM2.5 is 5µg/m3.
Due to high exposure to air pollution,Indians have on an average loose 1.51 years of their life.
The large exposure to PM2.5 has also reduced life expectancy for countries and regions—Egypt (2.11 years), Saudi Arabia (1.91 years), India (1.51 years) China (1.32 years) and Pakistan (1.31 years).
Almost 100% of the world population lives in areas where the PM2.5 levels exceeded WHO recommendations.
India was ranked as the ninth most exposed country to Ozone after Congo, Ethiopia, Germany, Bangladesh, Nigeria, Pakistan, Iran and Turkey.
The lowest impacts of pollution on longevity is in Norway, Sweden, Australia, and New Zealand.

10. IPCC warns of irreversible impact of global climate change
Tags: Popular Science and Technology
The Intergovernmental Panel on Climate Change (IPCC) has warned of a grim future for earth if global warming continues and the global temperatures continue to increase beyond 1.5% .
The latest warnings have come in the second part of IPCC’s Sixth Assessment Report which talks about climate change impacts, risks and vulnerabilities, and adaptation options. The first part of the report was released in August last year.
The Assessment Reports, the first of which had come out in 1990, are the most comprehensive evaluations of the state of the earth’s climate. Later reports were released in 1995,2001,2007 and 2015.
The report highlights the increasing impacts that are expected as the rise in global temperatures, currently around 1.1C, heads to 1.5Cabove the 1850s level.
Highlights of the report
South Asia is the most vulnerable to severe climate change impacts due to its inequality and poverty .
The Ganga, Indus, Amu Darya river basins in Asia will face severe water scarcity by 2050.It will adversely affect agriculture and drinking water scarcity in the region .
Ahmedabad city faces a risk of urban heat island effect . It means that the average temperature in the city will be higher than the surrounding areas.
Mumbai is at a high risk of rising sea level and consequent flooding
If the temperature increases by 1-4 degree centigrade then rice production in the world can fall by 10-30% and maize production can fall by 25-70%.
If temperatures rise to between 1.7 and 1.8C above the 1850s level, then the report states that half the human population could be exposed to periods of life-threatening climatic conditions arising from heat and humidity.
Rising Sea Level
According to the IPCC report, global sea levels will likely rise 44-76 cm this century if governments meet their current emission-cutting pledges. With faster emission cuts, the increase could be limited to 28-55 cm.
But with higher emissions, and if ice sheets collapse more quickly than expected, sea levels could rise as much as 2 m this century and 5 m by 2150.
Wet Bulb Temperature
Lucknow and Patna ,Bhubaneswar, Chennai, Mumbai, Indore, and Ahmedabad , are among the cities predicted to reach wet-bulb temperature of 35°C if emissions continue to rise.
Assam, Meghalaya, Tripura, West Bengal, Bihar, Jharkhand, Odisha, Chhattisgarh, Uttar Pradesh, Haryana and Punjab will be the most severely affected, but if emissions keep rising, all States will have regions that experience wet-bulb temperature of 30°C or more by the end of the century.
IPCC
The Intergovernmental Panel on Climate Change was set up by the World Meteorological Organisation and the United Nation Environment Programme in 1988.
Aim of IPCC
It was set up to prepare a comprehensive review and recommendations with respect to
- the state of knowledge of the science of climate change;
- social and economic impact of climate change,
- potential response strategies and elements for inclusion in a possible future international convention on climate.
Its Headquarters : Geneva, Switzerland

Concept Clearing
What is Wet Bulb Temperature
Human body regulates our body temperature depending upon the external environment of heat and humidity. If the temperature is high then our body tries to lower down our body temperature by sweating. The more we sweat the faster the cooling. However if humidity (water vapour in air ) is high then the ability of our body to cool also reduces . That’s why dry heat feels more tolerable than extreme humidity.
Wet-bulb temperature accounts for both heat and humidity, and reflects what that combination means for the human body’s ability to cool down.
The term wet bulb comes from a way the measurement can be taken, by wrapping a piece of wet cloth around the end of a thermometer to see how much evaporation can decrease the temperature.
35 degree centigrade is considered to be the maximum limit for a wet bulb temperature.
If the wet bulb temperature reaches 35 degree centigrade then a normal healthy human being cannot lose its body heat by sweating and will suffer heat stroke leading to death if they remain outdoors for a considerable period of time.
With the continuous rise in earth temperature the risk of wet bulb temperature phenomena is expected to become common.
