सारांश
The UN nuclear watchdog, the International Atomic Energy Agency (IAEA), has reported that the protective shield at the Chernobyl nuclear power plant in Ukraine has been damaged by drones. This shield, crucial for containing radioactive material from the 1986 disaster, is now compromised. Ukraine has quickly pointed fingers at Russia for the attack.
What does this mean? It's a serious concern for nuclear safety, especially in a war zone, as any damage to such critical infrastructure could have far-reaching environmental and health consequences. The IAEA's involvement highlights the international community's worry about the safety of nuclear facilities during conflicts.
पृष्ठभूमि
The Chernobyl nuclear power plant in Ukraine was the site of the world's worst nuclear disaster in 1986. Following the accident, a temporary 'sarcophagus' was built to contain the highly radioactive material. This was later replaced by the New Safe Confinement (NSC), a massive arch-shaped structure designed to safely enclose the damaged reactor unit for at least 100 years.
The facility, though decommissioned, still houses significant radioactive waste and requires constant monitoring and maintenance to prevent further environmental contamination. The ongoing conflict in Ukraine has raised serious concerns about the safety and security of all nuclear facilities in the country, including Chernobyl and Zaporizhzhia.
नवीनतम घटनाक्रम
The International Atomic Energy Agency (IAEA) has reported damage to the protective shield at the Chernobyl nuclear power plant, allegedly caused by drones. Ukraine has attributed the attack to Russia. This incident underscores the extreme vulnerability of critical nuclear infrastructure in active war zones.
Any damage to containment structures or safety systems could lead to the release of radioactive material, posing severe environmental and health risks not only locally but potentially across borders. The IAEA's involvement highlights the international community's alarm over the potential for a nuclear catastrophe due to military actions.
बहुविकल्पीय प्रश्न (MCQ)
1. Consider the following statements regarding the Chernobyl nuclear disaster and its aftermath: 1. The disaster occurred in 1986 due to a design flaw in an RBMK-type reactor, which is a graphite-moderated, water-cooled reactor. 2. The original 'Sarcophagus' was a temporary containment structure, later replaced by the New Safe Confinement (NSC) to ensure long-term safety. 3. The immediate cause of the disaster was a steam explosion followed by a graphite fire, releasing a significant amount of radioactive material. 4. The International Atomic Energy Agency (IAEA) was established primarily to regulate nuclear weapons proliferation, with civilian nuclear safety being a secondary concern. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.1, 2 and 3 only
- D.1, 3 and 4 only

सही उत्तर: C
Statement 1 is correct: The Chernobyl disaster in 1986 involved an RBMK (Reaktor Bolshoy Moshchnosti Kanalnyy - High-Power Channel-type Reactor) reactor, which is graphite-moderated and water-cooled, known for its positive void coefficient. Statement 2 is correct: The 'Sarcophagus' was indeed a temporary structure, and the New Safe Confinement (NSC) was built over it for long-term containment. Statement 3 is correct: The accident sequence involved a power surge, steam explosion, and subsequent graphite fire. Statement 4 is incorrect: The IAEA has a dual mandate: promoting the peaceful use of nuclear energy and preventing its use for military purposes. Civilian nuclear safety is a core and primary concern, not secondary.
2. With reference to the International Atomic Energy Agency (IAEA), consider the following statements: 1. The IAEA is an autonomous international organization that reports directly to the UN General Assembly and Security Council. 2. Its primary mandate includes promoting the peaceful use of nuclear energy and preventing its use for military purposes. 3. The 'Additional Protocol' to IAEA safeguards agreements is a voluntary measure designed to strengthen the agency's verification authority over nuclear programs. 4. India is a founding member of the IAEA and is subject to full-scope safeguards on all its nuclear facilities. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.1, 2 and 3 only
- D.1, 3 and 4 only

सही उत्तर: C
Statement 1 is correct: The IAEA is an independent intergovernmental organization within the United Nations system, reporting annually to the UN General Assembly and, when appropriate, to the Security Council. Statement 2 is correct: This accurately describes the IAEA's dual mandate. Statement 3 is correct: The Additional Protocol provides the IAEA with enhanced rights of access and information, strengthening its ability to verify the peaceful nature of nuclear programs. Statement 4 is incorrect: While India is a founding member of the IAEA, it is not subject to full-scope safeguards on all its nuclear facilities because it is not a signatory to the Nuclear Non-Proliferation Treaty (NPT) as a non-nuclear-weapon state. Only its civilian nuclear facilities, under specific agreements, are subject to IAEA safeguards.
3. Which of the following statements regarding major nuclear accidents and reactor types is/are correct? 1. The Fukushima Daiichi nuclear disaster (2011) involved a meltdown in Pressurized Water Reactors (PWRs) following a tsunami. 2. The Three Mile Island accident (1979) was a partial meltdown of a Light Water Reactor (LWR) in the USA. 3. RBMK reactors, like the one at Chernobyl, are graphite-moderated and water-cooled, known for their positive void coefficient. 4. India's nuclear power plants primarily use Pressurized Heavy Water Reactors (PHWRs) and are largely indigenously developed. Select the correct answer using the code given below:
- A.1, 2 and 3 only
- B.2, 3 and 4 only
- C.1 and 4 only
- D.1, 2, 3 and 4
उत्तर देखें
सही उत्तर: B
Statement 1 is incorrect: The Fukushima Daiichi plant used Boiling Water Reactors (BWRs), not Pressurized Water Reactors (PWRs). Statement 2 is correct: The Three Mile Island accident involved a partial meltdown of a PWR, which is a type of Light Water Reactor (LWR). Statement 3 is correct: RBMK reactors are indeed graphite-moderated and water-cooled, and their design flaw included a positive void coefficient, which contributed to the Chernobyl disaster. Statement 4 is correct: PHWRs form the backbone of India's nuclear power program, and India has achieved significant indigenous capability in their design and construction.
