Near Surface Disposal Facilities for Radioactive Waste


Book Description

This Safety Guide provides recommendations on how to meet safety requirements on the disposal of radioactive waste. It is concerned with the disposal of solid radioactive waste by emplacement in designated facilities at or near the land surface. The Safety Guide provides guidance on the development, operation and closure of, and on the regulatory control of, near surface disposal facilities, which are suitable for the disposal of very low level waste and low level waste. The Safety Guide provides guidance on a range of disposal methods, including the emplacement of solid radioactive waste in earthen trenches, in above ground engineered structures, in engineered structures just below the ground surface and in rock caverns, silos and tunnels excavated at depths of up to a few tens of metres underground. It is intended for use primarily by those involved with policy development for, with the regulatory control of, and with the development and operation of near surface disposal facilities.




Costing Methods and Funding Schemes for Radioactive Waste Disposal Programmes


Book Description

Reliable methods for estimating the cost of a radioactive waste disposal programme are crucial to ensure that the necessary funding for completing the disposal programme is available. Estimating the cost for disposal is, however, a challenging and complex task. Disposal programmes themselves are complex and long term undertakings, and conditions can be expected to change significantly over the time span during which a disposal programme is developed and implemented. This publication provides Member States with information on developing cost estimates for a disposal programme and establishing funding mechanisms. It will help readers in becoming informed clients by familiarizing themselves with the approaches and complexities in cost estimates and funding mechanisms for disposal. The publication is applicable to all waste categories and both near surface and geological disposal. It contains relevant examples and case studies from national programmes. The cost figures are intended to give an indication of the possible cost of certain parts or aspects of the disposal programme rather than to compare different disposal programmesÂ’ costs.




Borehole Disposal Facilities for Disused Sealed Radioactive Sources


Book Description

This Safety Guide provides recommendations on the safe disposal of disused sealed radioactive sources in borehole disposal facilities. Sealed radioactive sources are used all over the world for a wide range of purposes, in areas such as health, industry, research and agriculture. These sources are usually managed safely while in use, but States often experience challenges in their management once the sources reach the end of their useful lives. Even though they may no longer emit sufficient radiation for their intended purpose, disused sources are radioactive and potentially hazardous, and they need to be managed as radioactive waste. Written for regulators and others involved in the development and management of borehole disposal facilities, the objective of this Safety Guide is to provide recommendations on the commissioning, operation, closure, institutional control and regulation of borehole disposal facilities for disused sealed radioactive sources, and small volumes of low and intermediate level secondary waste generated during the management of these sources. This Safety Guide can also be used as a basis for reassessing and, where appropriate, upgrading the safety of existing borehole disposal facilities.




Borehole Disposal Facilities for Radioactive Waste


Book Description

This Safety Guide addresses the safety issues relevant To The disposal of disused sealed sources and provides guidance on meeting the safety requirements and criteria for such facilities. In addition to making recommendations on safety for borehole facilities, such as in site selection and characterization, design and operation, and for closure and post-closure, The Safety Guide also covers provision for containment and isolation, And The performance requirements of the engineered components of the disposal system.







Leadership, Management and Culture for Safety in Radioactive Waste Management


Book Description

This Safety Guide provides recommendations on how to comply with IAEA safety requirements on leadership and management for safety in the area of radioactive waste management. It presents updated guidance on developing and implementing management systems for safety during all steps of radioactive waste management. Emphasis is placed upon effective leadership and culture for safety. The publication is intended to be used by the regulatory body and organizations with responsibilities for directing, planning, or undertaking the management of radioactive waste; it is also intended to be used by the suppliers to such organizations of safety related services and products that support radioactive waste management.




Applicability of IAEA Safety Standards to Non-Water Cooled Reactors and Small Modular Reactors


Book Description

In response to an increase in global activities related to non-water-cooled reactors and small modular reactors, this new Safety Report documenting areas of novelty of these technologies when compared to the current fleet of reactors has been developed. The impact of these areas of novelty on the applicability and completeness of the IAEA safety standards is assessed in the publication. Gaps and areas for additional consideration are identified. The review undertaken to develop this report encompassed the safety standards related to the lifetime of these reactor technologies. The publication also considers the interface between safety, security, and safeguards in the design of these technologies.
