Presented detail of storage of hazardous waste used and produced at Slovenia's only nuclear power plant. The first part describes NEK, its history and its social responsibility, which is very important for today. Then comes a section on the operation of the
nuclear power plant, and I have focused the thesis on the division and specifics of NEK's hazardous waste storage. Finally, I have presented the legislation and environmental standards that apply in this area.

This seminar paper examines the management and storage protocols for hazardous radioactive waste at the Krško Nuclear Power Plant (NEK) in Slovenia. The primary focus is to analyze how different classes of radioactive materials are processed, stored on-site, and regulated to ensure environmental and human safety.
- History and developmental milestones of the Krško Nuclear Power Plant.
- Categorization and specific storage methodologies for low-, intermediate-, and high-level radioactive waste.
- Technical implementation of spent fuel management, including pool and dry storage solutions.
- Legal frameworks, national regulations, and international safety performance standards.
- Analysis of corporate social responsibility regarding environmental neutrality and sustainability.
Excerpt from the Book
2. STORAGE OF RADIOACTIVE MATERIAL IN A FACILITY
Most of the radioactive waste in Slovenia, 90%, is generated by nuclear power plants. Radioactive waste is objects, equipment or substances for which no further use is foreseen and whose radioactivity exceeds the limit allowed by law. Ionising radiation emitted by radioactive waste and other radioactive substances may be dangerous to humans and other living beings because of its radioactivity. If the radiation energy is significantly higher than the radiation normally present in the environment, it can cause temporary or permanent damage to cells. As with other radioactive substances, radioactive waste must therefore be handled in such a way as to prevent exposure of living beings to ionising radiation and the release of radioactive substances into the environment. This is why the radioactive waste we dispose of is always in solid form.˝ (ARAO, 2015) The radioactivity of a substance decreases over time, depending on the half-lives of the chemical elements in the process.
Radioactive waste is divided into two basic groups:
"Low- and intermediate-level radioactive waste (LLRW) emits ionising radiation, but not significant amounts of heat. Therefore, they do not need to be cooled, but they must be prevented from spreading into the environment through water or other streams by packaging or other barriers. This is also how we contain the radiation. Additional radiation shielding is not usually needed for low-level waste, but is usually needed for intermediate level waste. The radioactivity of NSRAW containing short-lived elements with a half-life of less than 30 years will be comparable to that of the natural environment after a maximum of 300 years due to radioactive decay.
Summary of Chapters
1. WHAT IS A NUCLEAR POWER PLANT?: This chapter outlines the fundamental principles of nuclear power generation and provides a historical overview of the Krško plant. It also details basic plant data and the organization's approach to corporate social responsibility.

Frequently Asked Questions
What is the primary scope of this paper?
The paper focuses on the operational storage and management procedures for various classes of radioactive waste generated at the Krško Nuclear Power Plant in Slovenia.
Which facility does the research specifically analyze?
The research is dedicated to the Krško Nuclear Power Plant (NEK), which is the only facility of its kind in Slovenia.
What is the central goal of this study?
The goal is to explain how NEK handles hazardous waste, moving from generation and temporary storage to regulatory compliance and long-term safety strategies.
Which scientific methodology is applied?
The work utilizes a descriptive approach based on technical documentation, official plant data, national legislation, and existing academic studies on nuclear waste management.
How is radioactive waste managed at the plant?
Waste is managed by strictly following safety regulations, utilizing protective barriers for low and intermediate waste, and using pool or dry storage for high-level radioactive materials and spent fuel.
Which keywords define this study?
Key terms include nuclear power plant, radioactive waste, storage, uranium, safety, NEK, and legislation.
Why is dry storage considered an important technical solution?
Dry storage is highlighted as a passive safety solution that requires no cooling medium or electricity, offering increased safety against environmental risks compared to traditional pool storage.
How does the plant ensure safety during fuel replacement?
During shutdown, which occurs every 18 months, systems undergo rigorous maintenance, and fuel elements are moved to a pool where water acts as both a heat sink and a radiation shield.
