Nuclear Waste Management: An In-Depth Guide to Navigating and Handling Radioactive Waste

As the world seeks cleaner and more efficient sources of energy, the role of nuclear power has become increasingly crucial. However, with great benefits also come great responsibilities, especially when it comes to managing nuclear waste. This radioactive waste carries significant environmental and health risks, which is why proper management and disposal methods are a top priority for industry leaders and policymakers alike. In this blog, we’ll explore the nuclear fuel cycle, various techniques for managing radioactive waste, international perspectives, environmental and health impacts, future innovations and research, and more. So, let’s dive into the depths of nuclear waste management.

The Nuclear Fuel Cycle:

Before delving into waste management techniques, let’s first understand the nuclear fuel cycle. This cycle describes the process by which nuclear power plants generate electricity. It consists of two phases, including the front end and the back end. Front-end steps prepare uranium for use in nuclear reactors and the Back-end steps ensure that used or spent but still highly radioactive, nuclear fuel is safely managed, prepared, and disposed of. It begins with the mining and milling of uranium, which is used as fuel for reactors. Nuclear reactors then generate heat by splitting uranium atoms in a process called nuclear fission. This heat is used to produce steam, that drives turbines for electricity generation. However, fission also produces a variety of radioactive isotopes, which are the source of nuclear waste.

Categorization of Waste:

  • Exempt waste (EW): This refers to the waste, which meets the criteria for clearance, exemption or exclusion from regulatory control for radiation protection purposes.
  • Very short lived waste (VSLW): This waste can be stored for decay over a limited period of up to a few years and then cleared from regulatory control as per arrangements approved by the regulatory body, for uncontrolled disposal, use or discharge. This class includes waste containing primary radionuclides with very short half-lives often used for medical and research purposes.
  • Very low level waste (VLLW): This refers to the waste that does not require a high level of containment and isolation and, is therefore suitable for disposal in near surface landfill type facilities with limited regulatory control. Such landfill type facilities may also contain other hazardous waste. Typical waste in this category includes soil and rubble with low levels of activity concentration.
  • Low level waste (LLW): This waste is above clearance levels, but with limited amounts of long-lived radionuclides. It requires robust containment and isolation for periods of up to a few hundred years and is fit for disposal in engineered near surface facilities. This class covers a very broad range of waste.
  • Intermediate level waste (ILW): This refers to the waste that because of its content, particularly of long-lived radionuclides, requires a greater degree of containment and isolation that provided by near surface disposal. However, ILW needs no or little provision, for heat dissipation during its storage and disposal.
  • High level waste (HLW): This refers to the waste with levels of activity concentration high enough to generate significant quantities of heat by the radioactive decay process or waste with immense amount of long-lived radionuclides that need to be regarded in the design of a disposal facility for such waste. Disposal in deep and stable geological formations usually several hundred meters or more below the surface is generally recognized option for the disposal of high-level waste (HLW).

Acts mandating the disposal of waste in India:

Activities concerning establishment and utilization of nuclear facilities and use of radioactive sources are carried out in India in accordance with the relevant provisions of the Atomic Energy Act, 1962.

The environmental protection aspects related to nuclear waste are governed by the Environmental Protection Act, 1986.

The regulations pertaining to radiation protection are governed by the Radiation Protection Rules, 1962. the Mines Minerals Prescribed Substance Rules, 1984 governs the Safety aspects in mining and milling of prescribed substances. The implementation of the Atomic Energy Safe Disposal of Radioactive Waste Rules, 1987 ensures the safe disposal of nuclear waste.

Radioactive Waste Management Techniques:

There are various techniques for managing radioactive waste, including Incineration, Storage, Shallow Burial, Deep Burial, In water, and Recycling.

1. Incineration

Incineration is a technique used to treat radioactive waste that cannot undergo other management methods. This technique involves burning the waste at high temperatures, reducing the volume and quantity of the waste. During the incineration process, the waste is heated to a high temperature, and the resulting ash is sent for further treatment. Incineration can be an expensive technique, as you need specialized equipment and expertise. Additionally, incinerators need to meet strict safety guidelines to ensure the health and safety of workers and the environment.

2. Storage

Storage is an important and common technique used for the management of low-level and intermediate-level radioactive waste. The waste is stored in containers to ensure radioactivity does not leak and harm the environment. These containers are placed in storage facilities, where they are monitored to maintain their integrity. Long-term storage is usually done underground, where waste is protected from external factors such as weather or natural disasters. Proper care should be taken, however, to prevent leaks, contamination, and breaches in security.

3. Shallow Burial

Shallow burial is a technique that involves burying the radioactive waste in a lined trench of several meters deep and covering it with a soil cover. The aim is to ensure that waste is securely contained and isolated from the environment. Shallow burial is commonly used for low-level and some types of intermediate-level waste. Adequate care and continuous monitoring are required to avoid any potential for leaks or infiltration of the soil. Since the waste is underground, this method can lead to fewer risks of harm for humans and the environment.

4. Deep Burial

Deep burial refers to burying the waste much deeper into the earth than shallow burial. This technique has the advantage of increasing the barrier between the waste and the environment, minimizing the risk of harm. Owing to the depth of burial, the waste is exposed to significant pressures, which can ensure containment. This technique is useful for radioactive materials with a long half-life, such as the spent fuel from nuclear power plants. However, the potential for waste leakage into the surrounding environment poses a significant threat and requires constant monitoring and safety protocols.

5. Transmutation

Transmutation is a new radioactive waste management technique that offers long-term solutions to managing radioactive waste. The technique involves changing radioactive elements into non-radioactive elements through the use of nuclear reactors and particle accelerators. The non-radioactive waste can then be recycled or disposed of without the risk of radiation.

6. In-Water and Recycling

In-water management involves disposing of liquid radioactive waste in offshore waters. Similar to shallow and deep burial, the aim is to ensure containment and isolation from the environment. Recycling is another method, which, as the name suggests, involves the reprocessing of waste for use again. This method is commonly used in nuclear plants, where spent fuel is reprocessed to extract the unused uranium and plutonium, which can be used in other processes. Recycling reduces the overall quantity of waste, and the material that cannot be reused can then be processed using other methods.
