This book was released on 2003 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the nuclear industry, many contaminated facilities that require decommissioning contain huge volumes of concrete. This concrete is generally disposed of as low-level waste at a high cost. Much of the concrete is lightly contaminated and could be reused as roadbed, fill material, or aggregate for new concrete, thus saving millions of dollars. However, because of the possibility of volumetric contamination and the lack of a method to evaluate the risks and costs of reusing concrete, reuse is rarely considered. To address this problem, Argonne National Laboratory-East (ANL-E) and the Idaho National Engineering and Environmental Laboratory teamed to write a ''concrete protocol'' to help evaluate the ramifications of reusing concrete within the U.S. Department of Energy (DOE). This document, titled the Protocol for Development of Authorized Release Limits for Concrete at U.S. Department of Energy Site (1) is based on ANL-E's previously developed scrap metal recycle protocols; on the 10-step method outlined in DOE's draft handbook, Controlling Release for Reuse or Recycle of Property Containing Residual Radioactive Material (2); and on DOE Order 4500.5, Radiation Protection of the Public and the Environment (3). The DOE concrete protocol was the basis for the ASTM Standard Guide for Evaluating Disposal Options for Concrete from Nuclear Facility Decommissioning, which was written to make the information available to a wider audience outside DOE. The resulting ASTM Standard Guide is a more concise version that can be used by the nuclear industry worldwide to evaluate the risks and costs of reusing concrete from nuclear facility decommissioning. The bulk of the ASTM Standard Guide focuses on evaluating the dose and cost for each disposal option. The user calculates these from the detailed formulas and tabulated data provided, then compares the dose and cost for each disposal option to select the best option that meets regulatory requirements. With this information, the reuse of concrete may be possible, thus reducing dose and decontamination and decommissioning costs. This paper outlines ten steps required to release concrete for reuse and discusses the disposal options covered in the ASTM Standard Guide.

Book excerpt: Sustainability of Life Cycle Management for Nuclear Cementation-Based Technologies, edited by Dr. Rahman and Dr. Ojovan, presents the latest knowledge and research on the management of cementitious systems within nuclear power plants. The book covers aging, development and updates on regulatory frameworks on a global scale, the development of cementitious systems for the immobilization of problematic wastes, and the decommissioning and decontamination of complex cementitious systems. The book's editors and their team of experts combine their practical knowledge to provide the reader with a thorough understanding on the sustainability of lifecycle management of cementitious systems within the nuclear industry. Sections provide a comparative tool that presents national regulations concerning cementitious systems within nuclear power plants, check international and national evaluation results of the sustainability of different systems, help in the development of performance test procedures, and provide a guide on aging nuclear power plants and the long-term behavior of these systems in active and passive safety environments. - Presents the latest information on the behavior of different cementitious systems used in the nuclear industry in one comprehensive resource - Includes scientific justifications of system behavior during the design, operation, maintenance and decommissioning phases - Aids the reader in the development of evaluation tests for problematic wastes

This book was released on 2005 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly all nuclear installations utilize stacks to discharge ventilation air as well as gases and fumes from contaminated areas. Over a service lifetime, stacks may become contaminated as the result of deposition of radioactive substances, such as aerosols on stack surfaces. In the longer term, this is a serious decommissioning issue.

This book was released on 2000 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The US Department of Energy (DOE) Order 5400.5, ''Radiation Protection of the Public and Environment'' contains provisions pertinent to releasing potentially radioactive materials from DOE facilities for reuse or recycle. A process of authorized release for materials recovered from radiation areas is permitted under Order 5400.5 and the proposed rule in Title 10, Part 834, of the Code of Federal Regulations (10 CFR Part 834). A generic disposition protocol to facilitate release of concrete under these provisions has been developed. This report analyzes the application of that generic protocol to site-specific cases at the Idaho National Engineering and Environmental Laboratory (INEEL). The potential radiological doses and costs for several concrete disposition alternatives for the sewage treatment plant (STP) at the Central Facilities Area (CFA) of INEEL were evaluated in this analysis. Five disposition alternatives were analyzed for the concrete: (A) decontaminate, crush, and reuse; (B) crush and reuse without decontamination; (C) decontaminate, demolish, and dispose of at a nonradiological landfill; (D) demolish and dispose of at a nonradiological landfill without decontamination; and (E) demolish and dispose of at a low-level radioactive waste (LLW) facility. The analysis was performed for disposition of concrete from four INEEL structures: (1) trickle filter, (2) primary clarifier, (3) secondary clarifier, and (4) CFA-691 pumphouse for a generic case (based on default parameters from the disposition protocol) and an INEEL-specific case (based on INEEL-specific parameters). The results of the analysis indicated that Alternatives B and D would incur the lowest cost and result in a dose less than 1 mrem/yr (except for the trickle filter, the dose for which was estimated at 1.9 mrem/yr) for nonradiological workers. The analysis indicated that the main contributor to the radiological dose would be cobalt-60 contamination in the concrete. A characterization conducted in 1996 was used in the analysis; therefore, because of radioactive decay, the resultant doses to receptors (now or later) would be less than the values reported in this analysis. For the generic case study, costs associated with Alternatives A and C were shown to be much smaller than for Alternative E. For the INEEL-specific case, in general, costs were much higher for Alternatives A and C than for Alternative E because of on-site disposal with zero disposal cost.

Book excerpt: "Decommissioning activities for zero-power reactors, radio-diagnostic and radiotherapy hospital departments and laboratories and factories using radioactive material may be erroneously perceived as trivial and of low priority. This publication provides practical information, experience and assistance aimed at a broad spectrum of practitioners who are faced with decommissioning of such small nuclear facilities. Particular consideration is given to the financial and scientific resources, and early planning, which are all factors essential to efficient and effective decommissioning. It is written as a simplified, stepwise approach for guidance to nuclear operators who may have little or no experience in decommissioning. An accompanying CD contains practical information in two Annexes, including descriptions of decommissioning projects problems encountered, solutions and analyses, and lessons learned"--Provided by publisher.
