People also ask
Q1: What is nuclear waste, and how is it generated?
Ans: nuclear waste, also known as radioactive waste, comprises materials containing radioactive isotopes that are no longer useful for their original purpose. It is generated through the fission process in nuclear reactors, where atoms of certain elements are bombarded by neutrons, leading to the production of radioactive byproducts.
Q2: What are some international conventions addressing nuclear waste?
Ans: Key conventions include the Bamako Convention, prohibiting the import of hazardous waste, including radioactive materials, into Africa. The Joint Convention on Spent Fuel and Radioactive Waste Management focuses on global standards for radioactive waste management. Additionally, the Convention on Nuclear Safety aims to enhance global nuclear safety standards.
Q3: What are the primary techniques used in waste handling?
Ans: Techniques include spent fuel storage, initially underwater for cooling before transferring to dry casks. Liquid waste treatment processes waste from nuclear plants before release. Advanced methods like vitrification and reprocessing manage high-level radioactive waste.
Q4: What are the main challenges associated with waste management?
Ans: Challenges include radioactive pollution, posing environmental and health risks. Storage challenges arise due to long-term radioactive waste. Safety concerns involve transportation accidents, requiring stringent measures. Additionally, the financial burden impacts energy production.
Q5: How does India manage waste within its nuclear program?
Ans: India employs on-site management strategies for handling waste generated at nuclear power stations, coupled with reprocessing facilities located in Trombay, Tarapur, and Kalpakkam. These facilities play a crucial role in processing spent fuel and managing radioactive waste. India also adheres to IAEA safeguards and monitoring measures to ensure the safe and secure handling of nuclear materials and waste.
