सारांश
India is increasingly turning to nuclear power as a vital component of its energy transition strategy, aiming to meet its growing electricity demands and achieve ambitious net-zero emission targets. The discussion highlights the need for reliable baseload power, which nuclear energy can provide, unlike intermittent renewable sources.
A key focus is on Small Modular Reactors (SMRs), which are seen as a promising technology due to their smaller size, modular design, and potential for faster deployment and enhanced safety. Essentially, India is exploring how nuclear energy, particularly advanced SMRs, can provide a clean, stable, and scalable power source to support its economic growth while combating climate change.
पृष्ठभूमि
India's energy demand is projected to grow significantly, driven by economic expansion and population increase. Historically, coal has been the backbone of India's energy sector. However, with increasing concerns about climate change and commitments to net-zero emissions, there's a strategic shift towards cleaner energy sources.
India's nuclear power program, initiated by Homi J. Bhabha, has been a long-term strategy for energy security, based on a three-stage fuel cycle leveraging the country's vast thorium reserves.
नवीनतम घटनाक्रम
Currently, India is actively exploring nuclear power as a vital component of its energy transition strategy. The focus is not only on expanding conventional nuclear capacity but also on adopting advanced technologies like Small Modular Reactors (SMRs).
SMRs offer advantages such as smaller size, modular construction, faster deployment, and enhanced safety features, making them attractive for meeting diverse energy needs and integrating with renewable sources to provide reliable baseload power. This exploration aligns with India's ambitious net-zero emission targets and the need for stable, clean energy to support economic growth.
बहुविकल्पीय प्रश्न (MCQ)
1. Consider the following statements regarding Small Modular Reactors (SMRs): 1. SMRs typically have a power output of less than 300 MWe and are designed for factory fabrication. 2. Their modular design allows for faster deployment and reduced construction costs compared to traditional large-scale nuclear reactors. 3. SMRs are inherently safer due to their smaller core and reliance on passive safety systems. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: D
All three statements are correct characteristics of Small Modular Reactors (SMRs). SMRs are defined by their smaller power output (typically up to 300 MWe), which allows for factory fabrication of components and modular construction. This modularity leads to faster deployment, reduced on-site construction time, and potentially lower costs per unit. Their smaller core size and often simplified designs allow for the incorporation of passive safety systems, which rely on natural forces like gravity and convection rather than active components, enhancing their inherent safety.
2. With reference to India's Three-Stage Nuclear Power Programme, consider the following statements: 1. The first stage focuses on Pressurised Heavy Water Reactors (PHWRs) using natural uranium and producing plutonium. 2. The second stage primarily focuses on using Thorium-232 as fuel in Fast Breeder Reactors (FBRs) to produce Uranium-233. 3. India possesses the world's largest known reserves of Thorium, which is the primary fuel for the third stage. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.1 and 3 only
- C.2 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: B
Statement 1 is correct. The first stage of India's nuclear power program involves PHWRs fueled by natural uranium, which produce plutonium as a byproduct. Statement 2 is incorrect. The second stage uses plutonium (produced in the first stage) and Uranium-238 in Fast Breeder Reactors (FBRs) to breed more plutonium and also to convert Thorium-232 into Uranium-233. Thorium-232 is not the primary fuel for the second stage; it's converted into U-233 for the third stage. Statement 3 is correct. India has significant thorium reserves, estimated to be the largest in the world, which is intended to be the primary fuel for the third stage of the program, utilizing U-233 in thorium-based reactors.
3. In the context of India's energy transition and net-zero targets, which of the following statements best describes the role of nuclear power as a 'baseload' source?
- A.Nuclear power plants can quickly adjust their output to match fluctuations in electricity demand.
- B.Nuclear power provides a consistent and reliable supply of electricity, operating continuously at high capacity factors.
- C.Nuclear power is primarily used to supplement intermittent renewable sources during peak demand periods.
- D.Baseload refers to the ability of nuclear reactors to be rapidly deployed in modular units.
उत्तर देखें
सही उत्तर: B
Baseload power refers to the minimum level of electricity demand required over a period of time. Baseload power plants are designed to run continuously at a high output to meet this constant demand. Nuclear power plants are characterized by their ability to operate continuously for long periods (often 18-24 months between refueling), providing a stable and reliable supply of electricity with high capacity factors, making them ideal baseload sources. Option A describes 'load following' capability, which is not a primary characteristic of traditional nuclear plants. Option C describes 'peaking power' or 'balancing power'. Option D describes a characteristic of SMRs related to deployment, not baseload operation.
4. Which of the following statements regarding the regulatory framework and international cooperation in India's nuclear energy sector is NOT correct?
- A.The Atomic Energy Regulatory Board (AERB) is an independent statutory body responsible for nuclear safety and radiation protection.
- B.India is a signatory to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) as a non-nuclear-weapon state.
- C.The Department of Atomic Energy (DAE) is directly under the Prime Minister's Office.
- D.India's civil nuclear cooperation agreements, such as with the USA, allow for transfer of nuclear technology and fuel under IAEA safeguards.
उत्तर देखें
सही उत्तर: B
Statement B is NOT correct. India has consistently refused to sign the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), viewing it as discriminatory because it creates a distinction between nuclear-weapon states and non-nuclear-weapon states based on a cut-off date. India maintains its nuclear weapons program outside the NPT framework. Statement A is correct; AERB is the primary regulatory body. Statement C is correct; DAE functions under the direct charge of the Prime Minister. Statement D is correct; India has entered into civil nuclear cooperation agreements with several countries, which involve IAEA safeguards on imported reactors and fuel.
