• Under the Companies Act, 1956, issuing securities to 49 people was considered private placement. This limit was raised to 200 under the Companies Act, 2013.
• Types of Private Placements: Preferential allotment and Qualified Institutional Placement (QIP).

Preferential Allotment:

Overview: Preferential allotment involves a company issuing new shares to a select group of existing shareholders or specific investors, usually at a price lower than the current market price.

Purpose: This method is often utilized when a company aims to reward or retain existing shareholders, such as promoters, by offering them the opportunity to purchase additional shares.

Regulation: Preferential allotment in India is regulated by SEBI regulations and the Companies Act. Companies require permission from their shareholders to proceed with preferential allotment.

Qualified Institutional Placement (QIP):

Overview: QIP is a private placement option exclusive to listed companies. It enables listed companies to issue shares or securities to qualified institutional buyers (QIBs), including mutual funds, banks, insurance companies, and foreign institutional investors, without going public.

Purpose: Companies often opt for QIP to efficiently raise capital from institutional investors for various purposes such as expansion, debt reduction, or other corporate needs.

Regulation: SEBI has established guidelines for QIP issuances in India to ensure transparency and fairness in the process.

However, with the advancement of nuclear power comes the complex challenge of managing nuclear waste effectively.

Understanding Nuclear Waste: Nuclear waste, also known as radioactive waste, comprises materials containing radioactive isotopes rendered obsolete for their original purpose. In a fission reactor, atoms bombarded by neutrons split apart, generating energy and forming nuclei of different elements. If these elements cannot undergo further fission, they become nuclear waste.

Nuclear Waste Management Conventions: Several international agreements aim to address nuclear waste management comprehensively:

• The Bamako Convention prohibits the import of hazardous waste, including radioactive waste, into Africa.
• The Joint Convention on the Safety of Spent Fuel Management and the Safety of Radioactive Waste Management is an IAEA treaty addressing the safe management of radioactive waste.
• The Convention on Nuclear Safety emphasizes safety standards for nations with nuclear power plants, promoting regular meetings to enhance safety levels.

Nuclear Waste Handling Techniques: Various techniques are employed for nuclear waste management:

• Spent Fuel Storage involves underwater storage for cooling before transferring to dry casks for long-term storage.
• Liquid Waste Treatment and Vitrification transform liquid waste into a glass-like material for storage.
• Reprocessing separates usable material from spent fuel.
• Geological Disposal entails burying nuclear waste deep underground in specially designed containers.

Issues Associated With Nuclear Waste: Radioactive pollution, harmful radiation emissions, and storage challenges pose significant environmental and safety concerns. Long-term storage of high-level waste remains a challenge due to its prolonged radioactivity, while ensuring secure storage facilities is crucial to prevent unauthorized access.
