BIMSTEC Foreign Ministers’ meet
GS Paper - 2 (International Relations)

The first-ever Foreign Ministers’ meeting of the Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC) began in Bangkok, Thailand. India’s External Affairs Minister S Jaishankar was also present, and said that areas of coordination challenge that were discussed, including health and energy security.

What is BIMSTEC?

BIMSTEC is a regional organisation that was established in 1997 with the signing of the Bangkok Declaration.
Initially known as BIST-EC (Bangladesh-India-Sri Lanka-Thailand Economic Cooperation), the organisation is now known as BIMSTEC and comprises seven members, with Myanmar joining towards the end of 1997, and Bhutan and Nepal in 2004.
Around 22% of the world’s population lives in the seven countries around the Bay of Bengal, with a combined GDP close to $2.7 trillion.
All seven countries have sustained average annual rates of growth between 3.4% and 7.5% from 2012 to 2016. A fourth of the world’s traded goods cross the bay every year.
Cooperation within the BIMSTEC had initially focused on six sectors in 1997 (trade, technology, energy, transport, tourism, and fisheries) and expanded in 2008 to other areas.
In 2021, a reorganisation led to each of the Member States leading certain sectors. India focuses on security, along with counter-terrorism and transnational crime, disaster management and energy.

Growth of BIMSTEC as a regional forum

Despite having been in existence for many years, the grouping had been largely ignored until India gave it a renewed push in October 2016, a month after the terrorist attack in Uri.
Alongside the BRICS summit in Goa, India hosted an outreach summit with leaders of BIMSTEC countries.
Weeks earlier, some of these countries had supported New Delhi’s call for a boycott of the South Asian Association of Regional Cooperation (SAARC) summit scheduled in Islamabad that November.
SAARC includes Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka as its members. When that summit was postponed, India claimed victory in isolating Pakistan.

China on mind

The Bay of Bengal is crucial for an increasingly assertive China in maintaining its access route to the Indian Ocean.
As China has undertaken a massive drive to finance and build infrastructure in South and Southeast Asia through the Belt and Road Initiative in almost all BIMSTEC countries, except Bhutan and India, BIMSTEC is a new battleground in the India-China battle for dominance.
BIMSTEC could allow India to push a constructive agenda to counter Chinese investments, and instead follow best practices for connectivity projects based on recognised international norms. The Chinese projects are widely seen as violating these norms.
The two organisations — SAARC and BIMSTEC — focus on geographically overlapping regions. However, this does not make them equal alternatives.
SAARC is a purely regional organisation, whereas BIMSTEC is inter-regional and connects both South Asia and ASEAN.
Since the SAARC summit has only been postponed, not cancelled the possibility of revival remains.

Nuclear-powered rocket cut travel time to Mars
GS Paper - 3 (Energy)

In less than three years, NASA could be testing a nuclear rocket in space. The space agency and the Defense Advanced Research Projects Agency, or DARPA, announced that Lockheed Martin had been selected to design, build and test a propulsion system that could one day speed astronauts on a trip to Mars. The program is named DRACO, short for the Demonstration Rocket for Agile Cislunar Operations.

What if a spacecraft could get to Mars in half the time it currently takes?

Every 26 months or so, Mars and Earth are close enough for a shorter journey between the worlds. But even then it is a pretty long trip, lasting seven to nine months. For most of the time, the spacecraft is just coasting through space.
But if the spacecraft could continue accelerating through the first half of the journey and then start slowing down again, the travel time could be slashed.
Current rocket engines, which typically rely on the combustion of a fuel like hydrogen or methane with oxygen, are not efficient enough to accomplish that; there is not enough room in the spacecraft to carry that much propellant.
But nuclear reactions, generating energy from the splitting of uranium atoms, are much more efficient.
The DRACO engine would consist of a nuclear reactor that would heat hydrogen from a chilly minus 420 degrees Fahrenheit to a toasty 4,400 degrees, with the hot gas shooting from a nozzle to generate thrust. Greater fuel efficiency could speed up journeys to Mars, reducing the amount of time astronauts spend exposed to the treacherous environment of deep space.
Nuclear propulsion could also have uses closer to home, which is why DARPA is investing in the project. The technology may allow rapid maneuvers of military satellites in orbit around Earth.

Flashback

Nuclear propulsion for space is not a new idea. In the 1950s and 1960s, Project Orion — financed by NASA, the Air Force and the Advanced Research Projects Agency — contemplated using the explosions of atomic bombs to accelerate spacecraft.
At the same time, NASA and other agencies also undertook Project Rover and Project NERVA, efforts that aimed to develop nuclear-thermal engines similar in concept to those now being pursued by the DRACO program.
A series of 23 reactors were built and tested, but none were ever launched to space. Until the end of this program in 1973, NASA had contemplated using nuclear reactors to propel space probes to Jupiter, Saturn and beyond, as well as to provide power at a lunar base.
The technical capabilities, including early safety protocols, remain viable today, Tabitha Dodson, the DRACO project manager, said in a news briefing on 2 August 2023.
A key difference between NERVA and DRACO is that NERVA used weapons-grade uranium for its reactors, while DRACO will use a less-enriched form of uranium. The reactor would not be turned on until it reached space, part of the precautions to minimize the possibility of a radioactive accident on Earth.

Poor nations forced to rely on fossil fuels
GS Paper - 3 (Energy)

Poor countries with heavy debts have been forced to continue to rely on fossil fuels for generating revenue to return the loans taken from richer countries and private lenders to meet various economic exigencies like the pandemic three years ago, a new report said. These countries, mostly in the global south, may find it impossible to phase out fossil fuels and transition to renewable energy as revenues from fossil fuel projects “are often overinflated and require huge investments to reach expected returns, leading to further debt”.

What is the “debt-fossil fuel trap”?

The report, ‘The Debt-Fossil Fuel Trap’, published on 21 August 2023 by the anti-debt campaigners Debt Justice and partners in affected countries.
The global south — a term used for developing, less developing and underdeveloped countries, located in Africa, Latin America, and Asia — countries are increasingly being burdened by enormous debts in recent years.
Their “external debt payments (money borrowed from richer countries, or multilateral creditors like the World Bank and IMF, or private lenders such as banks) has gone up by 150% between 2011 and 2023, reaching their highest levels in 25 years”, said the report.
Moreover, 54 countries are in a debt crisis — they had to cut their public sending budgets during the pandemic to repay the loans, the analysis found.
The situation is worsened by extreme weather events, which force these countries to borrow more money as they lack adequate finances and resources for adaptation, mitigation and tackling loss and damage.
For instance, Dominica’s debt as a percentage of GDP rose from 68% to 78% after Hurricane Maria hit the island in 2017.
To deal with the mounting debts, these countries have turned to extracting more fossil fuels.
The country’s strategy to reduce debt may end up adding to debt levels without generating adequate revenue to repay, which could force Argentia to further expand its fossil fuel projects, the report added. This is known as the “debt-fossil fuel trap”.
Ending the high debt burdens

The report has laid out a few recommendations to help global south countries exit the “debt-fossil fuel trap”.
It said clean energy, wealthy governments and institutions must implement “ambitious debt cancellation for all countries that need it, across all creditors, free from economic conditions.
They should also stop accepting repayments made through fossil fuel projects’ revenue.
Meanwhile, “Bilateral and multilateral finance should be aligned with a 1.5 degree warming scenario and fair shares calculations, and not be used to finance fossil fuels.

Fukushima nuclear water release
GS Paper - 3 (Nuclear Energy)

Twelve years after the Fukushima nuclear meltdown, Japan is releasing the power plant’s cooling water into the ocean. Japanese officials say it’s safe, but experts are divided. It’s hard to have a purely fact-based discussion about Japan’s Fukushima water release plan. Due to several scandals and a lack of transparency, trust appears to be low in both TEPCO, the company that operated the now-defunct Fukushima-Daiichi nuclear power plant, and the Japanese government, with its close ties to the atomic energy industry.

Fukushima: Why is the water being released into the Pacific Ocean?

Storage tanks holding the cooling water at the ruined facility are full. Japan has had to cool the reactors at the nuclear power plant since they were destroyed during a catastrophic tsunami in 2011.
It takes 170 tons of cooling water per day to keep them cool. In addition, rain and groundwater have been seeping into the site. There are 1,046 storage tanks holding 1,343 million cubic meters of water.
Once the water has been filtered, it is considered safe and sent through a one-kilometer (0.62 mile)-long tunnel before being released into the Pacific Ocean — a process that will take an estimated 30 years to complete. The radioactive waste, meanwhile, will remain on land.
Is Japan allowed to release filtered cooling water into the sea?

Both Japan’s atomic agency and the International Atomic Energy Agency (IAEA) have approved the plan.
The IAEA said Japan had met international safety standards and that “discharges of the treated water would have a negligible radiological impact to people and the environment.
They said it had been common practice for nuclear power plants worldwide to release used cooling water into the ocean for decades routinely.
However, environmental and fishing experts, as well as neighboring states, have accused Japan of downplaying the level of radiation in the cooling water.
They are concerned about far-reaching ocean contamination, potential environmental damage, a fall in fishing revenue and loss of reputation.
How will the water be prepared before it’s released?

Before it’s released into the ocean, the contaminated cooling water and groundwater will be sent through a filter system called the Advanced Liquid Processing System (ALPS).
ALPS can filter 62 different radionuclides — radioactive elements — but can’t filter out the radioactive isotope tritium.
So, TEPCO wants to dilute the water until the concentration of tritium is reduced to about 1,500 Becquerel per liter or less than a fortieth of the national safety standard. A becquerel (Bq) is a unit that measures the rate at which radioactive material emits radiation or how many atoms in the material decay in a given time.
TEPCO says that if the levels of tritium remain too high after filtration, they will repeat the process before releasing the water.
How dangerous is tritium?

Tritium is a form of hydrogen that occurs naturally in Earth’s atmosphere. It is radioactive but far less dangerous than cesium-137 or strontium-90 — both of which are life-threatening.
It emits a weak beta particle that can be stopped by a sheet of plastic or human skin.
It’s a different story if strontium-90 gets into the human body: “Strontium is absorbed by the bones, and once it’s in the crystalline structure of the bones, you can’t get rid of it again.

First indigenous electric tractor
GS Paper - 3 (Energy)

India has launched the country's first indigenous fully-electric tractor, named CSIR-PRIMA ET11. The tractor was developed by India's state-owned Council for Scientific and Industrial Research and Central Mechanical Research Engineering Institute (CSIR-CMERI). The CSIR-PRIMA E11 is designed to cater to small and marginal farmers with around two hectares or less of farmland.

Salient features of the CSIR PRIMA ET11

The first very important point is that entire tractor has been designed and manufactured with indigenous components and technologies.
The main purpose of the tractor is to cater the demand of agriculture field application, it has been designed in such a way that its dynamics, weight distribution, transmission engagements, then lever and pedal position everything has been well designed and considered.
Another USP of the developed technology is that it Women friendly. For this we have given special attention in the ergonomics, for eg: All the levers, switches etc have been placed for easy approach to the women.
The farmers can charge the tractor using conventional home charging sockets in 7 to 8 hours and operate the tractor for more than 4 hours at the field. Otherwise, a tractor can run more than 6 hours in case of normal Haulage operation.
Coming to Transmission: The tractor is being designed with a robust and efficient transmission system by using the semi Synchronized type gearing system. The design helps to achieve the desired efficiency in min cost.
The tractor is equipped with best in class hydraulic with lifting capacity of 500 kg or more. It implies that the tractor can lift implements required not only for field operation but also hauling operation. It is also to be mentioned that the tractor can tow 1.8-ton capacity trolley with a max speed of 25 kmph.
Coming to electric aspects the battery we have chosen as the state of art Lithium ion battery with Prismatic cell confirmation. It has deep discharge capability for farming application and has a life of more than 3000 cycles.
Another distinct feature, we have provided that there is a port called V2L i.e. vehicle to load, this means when the tractor is not in operation, it battery power can be utilized for other secondary applications like pump and irrigation etc.

Largest indigenously developed N-plant starts ops
GS Paper - 3 (Energy)

The third unit of the indigenously developed 700-megawatt electric (MWe) nuclear power reactor at the Kakrapar Atomic Power Project (KAPP3) in Gujarat has commenced operations at full capacity. This comes a little over three years since the unit achieved its ‘first criticality’ – a technical term that signifies the initiation of a controlled, but sustained nuclear fission reaction – in July 2020. On 30 June this year, the unit had started commercial operations.

More about the News

In India’s civilian nuclear programme, this is seen as a landmark event, given that KAPP-3 is the country’s first 700 MWe unit and the biggest indigenously developed variant of the Pressurised Heavy Water Reactor (PHWR).
The PHWRs, which use natural uranium as fuel and heavy water as moderator, constitute the mainstay of India’s nuclear power fleet.
Till now, the biggest reactor of indigenous design was the 540 MWe PHWR, two of which have been deployed in Tarapur, Maharashtra.
For India, the operationalisation of its first 700MWe reactor is a significant scale up in technology, both in terms of the optimisation of its PHWR design — the new 700MWe unit addresses the excess thermal margins and also marks an improvement in the economies-of-scale, without significant design changes to the 540 MWe reactor.
Flashback

As India works to ramp up its existing nuclear power capacity of 7,480 MWe to 22,480 MWe by 2031, the 700MWe capacity would constitute the biggest component of this expansion plan. Currently, nuclear power capacity constitutes around 2 per cent of the total installed capacity of 4,17,668 MW (May 31).
Significantly, as India’s civilian nuclear sector gears up to its next frontier — building a 900 MWe Pressurised Water Reactors (PWRs) of indigenous design – the experience of executing the larger 700MWe reactor design would come in handy, especially with respect to the improved capability of making large-size pressure vessels, alongside India’s own isotope enrichment plants being developed to supply a part of the required enriched uranium fuel to power these new generation reactors over the next decade or so, according to DAE officials.
The first ‘pour of concrete’ for laying the foundation of KAPP-3 happened in November 2010 and this unit was originally expected to be commissioned in 2015.

Cabinet approves VGF for battery storage system
GS Paper - 3 (Energy)

The Union Cabinet has approved a scheme for providing viability gap funding (VGF) for developing battery storage of 4 gigawatt (Gw) by 2030-31. The VGF for the battery energy storage system (BESS) will have an initial outlay of Rs 9,400 crore and this will include a budgetary grant of Rs 3,700 crore.

More about the News

The VGF would be disbursed in five tranches and be linked with the various stages of implementation of BESS projects. The scheme is aimed at supporting the energy storage needs of the renewable energy sector, especially solar and wind.
Given their restricted hours/seasons of operation, energy storage ensures round-the-clock green energy.
The VGF scheme for BESS projects was first announced in Budget 2023. Through the scheme, the Centre is aiming to bring down the cost of battery storage systems and increase their viability.
By offering VGF support, the scheme targets achieving a Levelized Cost of Storage (LCoS) ranging from Rs 5.50-6.60 per kilowatt-hour (kWh), making stored renewable energy a viable option for managing peak power demand across the country, said a statement by the ministry of power.
The statement further said that 85 percent of BESS projects under the scheme would be provided to the power distribution companies (discoms).
This will not only enhance the integration of renewable energy into the electricity grid but also minimise wastage while optimising the utilisation of transmission networks. Consequently, this will reduce the need for costly infrastructure upgrades.
Developers for these BESS projects would be selected through a competitive bidding process, to be open for both public and private sector. This approach will foster healthy competition and encourage the growth of a robust ecosystem for BESS, attracting significant investments and generating opportunities for associated industries.
