China Unveils World's First Thorium Nuclear Reactor; Where Does India Stand?
China launched its thorium power project in 2011 with a $444 million investment. India, rich in thorium reserves, has explored this concept for decades
China has achieved a significant milestone by constructing the world's first thorium-based nuclear reactor. This feat comes against the backdrop of the ongoing trade war with the US. The revolutionary reactor, known as the Thorium Molten Salt Reactor, has been installed in the Gobi Desert in Wuyi city, Gansu province.
The project, initiated in October 2023, aims to generate two megawatts of electricity. While this is a monumental breakthrough in nuclear science, experts caution that large-scale electricity generation from thorium reactors will take time.
China embarked on this thorium electricity generation project in 2011, investing a substantial $444 million. Thorium reactors are advantageous as they produce less radioactive waste compared to uranium and are relatively safer. Additionally, thorium is difficult to use for nuclear weapons, which is a significant security benefit. China is now focusing on constructing a larger 10 MW thorium reactor, scheduled for installation by 2030.
India has long been acquainted with the thorium reactor concept, boasting the world's largest thorium reserves.
Thorium itself is not a nuclear fuel but can be converted into uranium-233, which is used in reactors. Despite the complex and costly conversion process, India made considerable strides in nuclear power starting in the 1950s under Dr. Homi Jahangir Bhabha, a renowned nuclear scientist.
Bhabha's vision was to leverage India's extensive thorium reserves in light of its limited uranium resources. Research by the Bhabha Atomic Research Centre and other institutions yielded successful results.
China's Lead And Global Progress
The US experimented with a 7.4 MW thorium reactor in the 1960s. Germany also experimented with thorium reactors in the 1970s and 1980s, with similar endeavours by Canada, Norway, Japan, Denmark, and the Netherlands.
Amongst these nations, India and China have emerged as leaders in thorium-based nuclear energy research, with India maintaining a prominent position in this field.

Sree Chitra transfers Parkinson's care tech to industry partners
THIRUVANANTHAPURAM: The Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST) has transferred five advanced medical technologies to industry partners, paving the way for their commercial production and broader clinical use. Among the developments is a Deep Brain Stimulator, an implantable device designed to manage movement disorders such as Parkinson's disease and dystonia. Developed by a multidisciplinary team from SCTIMST in collaboration with the Bhabha Atomic Research Centre, the device offers a cost-effective, indigenous alternative to imported stimulators. Another major innovation is a chitosan-based wound dressing sponge, intended for the treatment of chronic and infected wounds. The dressing delivers antibiotics directly to the site of infection, neutralises free radicals, and promotes faster healing while reducing the risk of systemic toxicity associated with oral or injectable antibiotics. The institute has also developed a small-scale plasma fractionation technique that enables the extraction of four critical proteins—fibrinogen, thrombin, albumin, and immunoglobulin—from blood plasma. These proteins can be used in specific combinations to aid blood clotting and manage immune-related conditions. Additionally, SCTIMST has created a device to transfer laboratory mice without causing stress. The Mice Transfer and Enrichment Box is designed to improve animal welfare standards in laboratory environments. The technologies have been licenced to various companies for commercial development. The Deep Brain Stimulator has been transferred to Shree Pacetronix Ltd in Madhya Pradesh. Intracranial and subdural electrodes, along with the plasma protein extraction technology, have been handed over to Synapticore Technology Pvt Ltd. The chitosan-based wound dressing has been transferred to Vranova Biotech Pvt Ltd in Mumbai.

A horticulturist bids adieu to the magnificent trees of TIFR
MUMBAI: For over three decades, Rajendra Gumaste has tended to the acres of greenery in a pocket at the southern tip of Mumbai set up by scientist extraordinaire Homi Bhabha. Now, as he prepares to move on to other pastures, he leaves to it the distilled essence of his years of work there, sprinkled with archival finds and curiosities, in the form of a coffee table book titled 'Trees of Tata Institute of Fundamental Research'. 'When Dr Bhabha got this piece of land in Colaba in the 1950s to house TIFR, it was mostly barren reclaimed land,' said Gumaste, speaking before the book's launch at the seaside campus on Thursday. 'Even though this was to be a den of scientific inquiry, he gave as much importance to nature in over 20 acres, almost half of the campus.' When Mumbai was in its teething stages, sacrificing trees to make way for people, Bhabha was making space for the former. 'Around half the trees here are transplanted from other parts of Mumbai, including Banyan trees, baobabs and peepal trees,' said Gumaste. 'He also imported rare species like the Melaleuca leucadendra and Tabebuia rosea.' Today the campus has over 2,000 trees in 110 varieties. The unmistakable star of this transplanting effort lies in the campus: a gigantic Banyan tree, one of the approximately 20 on campus, whose canopy spreads out over 6,000 square feet. 'This is not the oldest Banyan tree in Mumbai, but it is the only one that has been given this much space to spread its wings to its heart's desire,' said Shyam Palkar, assistant professor of botany at MES' DG Ruparel College. Gumaste met Palkar, who is part of a group called 'Friends of Trees', back in 2024 on a tree walk he was conducting at TIFR. They became great friends, and Palkar came on board as the book's editor and added botany and taxonomy details to it. Another feat of transplantation is one of the four baobab trees on campus. 'This baobab was transplanted from Nepeansea Road in 1972, when it was approximately 50 years old,' said Gumaste. 'The archive notes that Bhabha's brother, J J Bhabha, saw the tree being cut and asked the then director if it was possible to transplant it. Despite being an expensive endeavour, they still went ahead with it, with funding by Telco. There is a photo of the night it was being transplanted, with JRD Tata and J J Bhabha, looking up to its branches, a banner about its transplantation hanging between two trees in the background.' For Gumaste, who began his role as the head of gardens and parks at TIFR—he retired in 2024 but continues as a consultant—the challenges of tending to the trees have increased over the years due to the change in weather, temperature and rainfall patterns. 'Every monsoon, there are a few tree falls, especially those trees that are not native to Bombay like the gulmohar and spathodea, and the newer ones planted to fill the gaps,' he said. 'It is even trickier over here, as this is reclaimed land, and soil does not always allow the roots to bind firmly. During Cyclone Tatukae in 2021, we lost 48 trees.' Following in the footsteps of Bhabha, Gumaste and his 40-50 gardeners hoisted 32 of the trees right back up. Gumaste has also continued adding trees, preferring to choose the native varieties for a better survival rate. A few acres ahead, the greenery changes shape and leads to well-manicured French-style lawns with a hedge of Putranjiva trees around it and flowers decorating the borders. In the centre is a flower arrangement. Gumaste explains, 'While the flowers in it change according to the seasons, its shape—an amoeba—stays the same, as that is what Bhabha wanted.' Step another three acres ahead, and the greenery once again changes form into one mimicking a forest of wispy Casuarina equisetifolia trees, again at Bhabha's behest. 'This is a tree great for the seashore, as it bonds well in the sandy soil, breaks the wind, and prevents soil erosion,' said Gumaste. 'We keep reconstructing small gazebos here, as professors like to take lectures here, but the younger trees often fall during the monsoon and break them.' Gumaste credits his band of gardeners with keeping Bhabha's dream alive. For the book, he thanks the contributions of Palkar, designer Neil Daptardar and two TIFR photographers Vijay Shinde and Jatin Acharya, as well as Friends of Trees and the TIFR Alumni Association. 'We desperately need to bring back that sense of reverence and exaltation of trees,' he said. ('Trees of Tata Institute of Fundamental Research' is available with the TIFR Alumni Association for ₹1,500)

This Is Why India's First Nuclear Test In 1974 Was Delayed By 5 Minutes
Last Updated: Though termed a 'peaceful nuclear explosion,' the 1974 test proved India's nuclear capability, placing it among the world's elite group of nuclear-armed nations Fifty-one years ago, India surprised the world by conducting its first nuclear test under the leadership of then Prime Minister Indira Gandhi, often referred to as the Iron Lady. She described the test as a 'peaceful nuclear explosion." However, the United States, displeased with the move, responded by cutting off the supply of nuclear materials and fuel to India. The test marked a turning point in India's history, signalling the beginning of its nuclear journey. Despite opposition from the global nuclear non-proliferation regime, India's so-called 'peaceful' nuclear explosion positioned it among the select group of nations with nuclear capabilities. On May 18, preparations for the nuclear test were finalised. A scaffold was set up five kilometres away to monitor the explosion, where senior military officers and scientists gathered to observe. Scientist Virendra Sethi was sent to the test site for a final inspection. However, when the jeep at the site failed to start, Sethi had to walk two kilometres to the control room, resulting in a five-minute delay from the scheduled 8 a.m. detonation time. Seven Years Of Hard Work After seven years of dedicated effort, a team of 75 scientists and engineers successfully brought the top-secret nuclear project to completion. The initiative was led by Dr. Raja Ramanna, then Director of the Bhabha Atomic Research Centre (BARC). Among his team was APJ Abdul Kalam, who would later go on to lead India's 1998 Pokhran nuclear tests. India Faced A Dilemma Over Nuclear Path India's political leadership remained conflicted about pursuing a nuclear weapons program. Despite growing security concerns, Prime Minister Jawaharlal Nehru was reluctant to develop nuclear arms, even after China conducted its first nuclear test at Lop Nur in 1964. His successor, Lal Bahadur Shastri, also resisted domestic pressure to carry out nuclear tests in response. Instead, during his 1964 visit to Britain, Shastri sought security assurances from established nuclear powers rather than opting for an indigenous nuclear build-up. Indira Gandhi Adopted A Firm Stance When Indira Gandhi became Prime Minister in 1966, she charted a different course from her predecessors. Unlike Nehru and Shastri, who were cautious about pursuing nuclear weapons, Gandhi adopted a tougher and more pragmatic stance, particularly toward the discriminatory Nuclear Non-Proliferation Treaty (NPT). She gave the green light to India's nuclear establishment to develop the capability for a functional nuclear explosion—one that could be presented as a peaceful test if needed. After years of determined work by Indian nuclear scientists through the 1960s and early 1970s, the country was finally prepared for a defining moment. On May 18, 1974, India conducted its first nuclear test—Pokhran-1—code-named Smiling Buddha, in an underground facility in Rajasthan. Though officially described as a 'peaceful nuclear explosion," the test effectively showcased India's nuclear weapons capability, placing the country in the elite group of nuclear-armed nations. The successful detonation triggered a surge of national pride, but it also drew sharp international criticism and heightened concerns of a potential arms race in South Asia.
