The Fourth Industrial Revolution (IR 4.0) refers to the current and developing era of technological changes and advancements, characterized by the integration of advanced technologies like artificial intelligence (AI), robotics, the Internet of Things (IoT), 3D printing, genetic engineering, quantum computing, and other technologies. It has the potential to revolutionize the world in every aspect of human life, from manufacturing and transportation to healthcare and education. For instance, IR 4.0 promises to increase efficiency and productivity through the use of automation, artificial intelligence, and other digital technologies. This could lead to significant improvements in areas such as healthcare, where Al and machine learning algorithms can be used to analyze medical data and improve diagnoses and treatments. Moreover, it can make logistics and global supply chains more effective in driving economic growth. However, IR 4.0 also presents challenges and potential risks, such as job displacement due to automation and the need for upskilling and reskilling of workers to adapt to the new technological landscape. It could yield greater inequality, particularly in its potential to disrupt labor markets. There are also concerns around data privacy and security, as well as the ethical implications of the use of Al and other advanced technologies. In consideration of the above potential challenges, the Indian government should focus on the following key areas to aid Indian enterprises:

• Encourage R&D and increase investments in technology: India spends a meager 0.6 to 0.7 percent of its GDP on research and development. Investing in R&D is critical as enterprise survival will depend on adopting new technologies and boosting factor productivity. As a result, an investment policy specifically for the fourth industrial sector is required. This will improve technology absorption in the Indian economy and prepare it for the fourth industrial revolution. Introducing a generous reward system tied to technology could also aid India in attracting investment.
• Investing in upskilling and reskilling: The introduction of Automation and Cyber-Physical Systems in the manufacturing process needs a better-skilled workforce, which understands the complexity of the process. Thus, a national strategy for reskilling the labor force that becomes unemployed due to technological shocks and an intricate social security net should be established to reduce negative social repercussions.
• Enhance future human capital: Human capabilities drive innovation, which is a continuous and progressive process. Therefore, the government must focus on an education curriculum that instills sophisticated cognitive capabilities, such as high-level problem solving, skills to adapt to new technology, reasoning, and lessons related to socio-behavioral components required to create a future-ready workplace.
• Emphasizing cyber security: With the increasing use of technology, the risk of cyber-attacks also increases. Indian enterprises need to invest in robust cyber security measures to protect their data and intellectual property.
• Enhancing regulatory framework: The Indian Government needs to review and update the regulatory frameworks to ensure that they are appropriate for the digital age, while also protecting the rights and privacy of individuals.

The rapidly changing technology landscape offers India a good opportunity to industrialize. The democratic nature of technology may be able to assist Indian businesses in overcoming their legacy issues and becoming globally competitive. To secure India’s active involvement in the fourth industrial revolution, it will be necessary to restructure some vital domestic industries and strengthen institutional capability.

Small modular reactors (SMRs) are advanced nuclear reactors that have a power generation capacity of up to 300 megawatts (MW) per unit, which is one-third the capacity of a traditional nuclear reactor. They have been in growing demand because being mobile and due to agile technology, SMRs can be factory-built vis-a-vis the conventional nuclear reactors that are built on-site. Thus, it is a promising technology in industrial de-carbonization, especially where there is a requirement for a reliable and continuous supply of power. Prospects of setting up SMRs in India:

• Cover rural areas: They can be built in locations not suitable for larger nuclear power plants.
  • In areas lacking sufficient lines of transmission and grid capacity, like rural regions, SMRs can be installed into an existing grid or remotely off-grid, as a function of its smaller electrical output, providing low-carbon power for industry and the population.
• Safer alternative: In comparison to the existing reactors, SMR designs are generally simpler, and the safety concept for SMRs often relies more on passive systems and inherent safety characteristics of the reactor, such as low power and operating pressure.
  • These increased safety margins, in some cases, eliminate or significantly lower the potential for unsafe releases of radioactivity to the environment and the public in case of an accident.
• Affordable: Pre-fabricated units of SMRs can be manufactured and then shipped and installed on-site, hence resulting in savings in cost and construction time.
• Reduced fuel requirements: Power plants based on SMRs may require less frequent refueling, every 3 to 7 years, in comparison to between 1 and 2 years for conventional plants.
• Energy security: SMRs can offer a reliable and constant source of clean energy, which could enhance India’s energy security by reducing its dependence on imported fossil fuels.

Challenges of setting up SMRs in India:

• Licensing and regulation: Deriving license and regulation protocols will require substantial research into the design safety parameters catering to SMRs.
• Safety concerns: Nuclear power plants, including SMRs, have the potential to cause significant harm in the event of an accident or malfunction. Therefore, ensuring the safety of SMRs is of utmost importance and requires a robust regulatory framework, skilled personnel, and adequate emergency response plans.
• Nuclear waste disposal: Effective management of nuclear waste remains a crucial problem for the nuclear industry and a major concern of the public as well.
• Public perception: There is a general lack of trust and concerns from local communities over the addition of nuclear power plants.
  • The anti-nuclear protests outside nuclear power plants in Kudankulam, Tamil Nadu, and Jaitapur, Maharashtra are two significant resistance movements in the last two decades.

To address the above challenges, the government should frame a collaborative licensing process suitable for SMRs without compromising India’s strategic interests. The integration of SMRs in India’s existing nuclear power program can also be done in both grid and off-grid approaches. Moreover, India can collaborate globally, such as Cooperation in Reactor Design Evaluation and Licensing, to develop staffing requirements, basic safety specifications, and regulation and licensing protocols suitable for SMRs. Although integrating SMRs into the nuclear power grid will take time, working on a concept of SMRs that suits India’s current nuclear energy regime is a crucial opportunity for India to address the factors that have contributed to the lag in nuclear energy growth in the country.
