Technical Program

Nuclear Fuel Cycle Policy, Regulation and Safeguard/Nonproliferation

Session is prepared including the policy of nuclear fuel cycle, the safe regulation on the radioactive waste management and the issues both on safeguard and nonproliferation. The policy of nuclear fuel cycle in this session accommodates the recent issues on the national policy and the legal structure on the overall radioactive wase management issues both for spent nuclear fuel, HLW and for LILW. The safe regulation, in this session, accommodates the overall national regulatory activities concerning the nuclear material, the spent nuclear fuel, HLW and LILW on the radioactive waste management. Issues both on safeguard and nonproliferation are also includes for the safeguards, the import&export control, the physical protection and the cyber securities of nuclear materials.

Radioactive Waste Treatment

Radioactive waste treatment refers to convert a wide variety of radioactive waste materials into forms that are suitable for their subsequent management of radioactive waste of liquid, solid and gas discharge from nuclear industry operations with the goal of protecting people and the environment.
Radioactive waste of various types results from any activity that makes use of radioactive materials, including medical and industrial uses. Whatever their origin, radioactive wastes have to be managed safely and economically.
The Radioactive waste treatment session welcomes paper and presentations and is to encompass : Technology development, demonstration, and deployment, waste minimization, waste characterization and analysis, effluent monitoring, waste form and facility performance assessment, regulations and standards

LLW/ILW Disposal

The safe management of radioactive waste is a national task required for sustainable generation of nuclear power and for other beneficial applications with radio isotope. All countries with nuclear power generation program produced a certain amount of radioactive waste, both low-and intermediate-level of LLW/ILW. Moreover, due to a side application of radioisotopes (RI), the RI waste generation from industries, hospitals, and research organizations is also increasing. Unavoidably, many issues in related to LLW/ILW have arisen and thereby discussions and shares for the issues will be essential to resolve the tackles from the management. In that regard, this sections mainly covers LLW/ILW disposal for proper and final management of radioactive wastes generated from various sectors in application of nuclear energy. Area of the section composed of that includes This LLW/ILW disposal section welcomes papers and presentations with regard to disposal facility design, licensing and construction, transportation to disposal, radioactive waste treatment for pre disposal. And it also covers safety assessment and operation experience of disposal facility, site and environment survey and its assessment, development of solidification of LLW/ILW, classification of radioactive wastes, and procedure of waste acceptance with development of proper waste acceptance criteria and any other related issue to disposal of LLW/ILW.

Spent Nuclear Fuel (SNF) Storage

Spent nuclear fuel (SNF) refers to uranium-bearing fuel elements that have been used at nuclear reactors and that are no longer producing enough energy to sustain a nuclear fission reaction. The SNF needs management with special care due to its high radioactivity, radiotoxicity, and decay heat until it is finally disposed in geological repository. Whatever fuel cycle policy is selected in a country, storage for a specific period of time is a necessary and inevitable management step. There are two acceptable storage methods for SNF after it is removed from the reactor core: wet storage and dry storage. Right after discharge from nuclear reactor, SNF is stored in reactor side pool for cooling and transferred to designated wet or dry storage facilities, where it will await final disposal or reprocessing. The dry storage is an option adopted in most countries and the extension of dry storage period is anticipated because of the delay in the installation of the final disposal facility. Transport of SNF is also an essential management step. Spent nuclear fuel may be transported from a reactor pool to another pool, storage facility, research facility or disposal facility. Protection of people and environment from the radiological hazard posed by SNF is the key objective during the storage and transport of SNF and maintaining retrievability and integrity of SNF is another important objective to facilitate subsequent management steps following storage.

This session welcomes contributions regarding storage and transport of SNF covering but not limited to the following topics: SNF storage and transport systems, safety and risk assessment of SNF storage and transportation, SNF and cladding characterization, fuel retrievability and integrity assessment, management of damaged fuel, aging management of SNF and storage systems, monitoring and inspection during storage, security and non-proliferation issues of storage and transportation of SNF.

SNF/HLW Disposal

Safe, sustainable and effective geological disposal of spent nuclear fuel and high-level radioactive wastes is urgent matter to be solved for peaceful use of nuclear power including stable supply of electricity in countries generating nuclear energy. Safety is the most important of all, and long-term research and development is needed so that the risks arising from the current generation do not burden future generations.
Geological disposal system generally consists of multiple barriers of natural and engineered barriers, and its safety and performance should be verified through Underground Research Laboratory (URL). In addition to the technical contents, social aspects such as public acceptance are also important, and to this end, research for higher safety and efficiency of the geological disposal system is being conducted in each country considering SNF/HLW disposal.

This session welcomes contributions from specialists in geology, nuclear engineering, rock mechanics, geochemistry, hydrology, civil engineering, and environmental engineering for discussing and sharing ideas and knowledge on technology, engineering and associated research and development to support the development and implementation of a disposal repository for high level radioactive waste (HLW) including spent nuclear fuel (SNF).

Technical paper / abstracts are invited in the following topic areas:
- Site selection
- Natural barrier system
- Engineered barrier system
- Nuclide migration within geological disposal system
- Design and performance assessment of geological disposal system
- Natural analogues
- Underground research laboratory (URL)
- Concept and design of alternative disposal system
- Closure and monitoring of disposal facilities

Decontamination & Dismantling (D&D), Environment

Decontamination and decommissioning refer to a series of activities to remove radioactive contamination or to demolish the facility and site by applying various technologies when nuclear facilities are out of operation. Decontamination and decommissioning must consider both economical, environmental and safety aspects. It is difficult to satisfy all three considerations, so several factors need to be studied and reviewed. Therefore, environmentally friendly technologies as well as reasonable and optimized technologies must be considered when demolishing the facility and site or removing radioactive contamination. Environmental safety includes all activities associated with the radiation monitoring, sample analysis and characterization, risk assessment, and remediation technologies of nuclear facilities.

Decontamination and dismantling technology is a comprehensive technology in which several technologies are fused and combined, such as cutting, remote/automation, monitoring, handling and contaminant removal technology and so on. To this end, decontamination and dismantling technologies are developing in various fields, such as improving existing technologies or developing technologies through new concepts.
The goal of this session is to improve your understanding of decontamination and decommissioning as well as environmental safety through discussion of experiences, new technologies, and improvements to existing technologies and so on. This session welcomes the participation of environmentalists, physicists, nuclear engineers, chemists and soil scientists to share experiences/ideas and discuss new and improved technologies.
