This book was released on 2021-10-08 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication reports on the DACCORD project, which supports Member States in preparing preliminary cost estimates for the decommissioning of research reactors. The report is of particular benefit to programmes with limited decommissioning experience. Costing projects for the decommissioning of research reactors can be broad in scope with many possible inputs and influences that require due consideration in developing the estimate. The publication provides information on unit factors for research reactor decommissioning and a basis for estimating uncertainties and contingencies and for assessing the impact of decommissioning planning and characterization activities. It also addresses the use of the CERREX-D2 (Cost Estimate for Research Reactors in Excel) software code, developed by the IAEA to enable non-specialist users to develop preliminary cost estimates for decommissioning.

This book was released on 2018-02 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is intended to assist those Member States with limited decommissioning expertise, to estimate the overall cost of decommissioning during the early planning stages. The lack of published data has made it difficult to benchmark estimated costs against international practice. The DACCORD (data analysis and collection for costing of research reactor decommissioning) project was established to address this deficiency. Based on the outcome of the three main working groups, this publication provides representative input data and benchmarking data needed for the costing of research reactor decommissioning at preliminary planning stages. All detailed cost cases considered in the DACCORD project are presented in a special format, following a software tool, developed by the IAEA, and which helps to ensure uniformity of the presented data and generally to facilitate the analysis of the available information.

Download or read book International Structure for Decommissioning Costing (ISDC) of Nuclear Installations written by Organisation de coopération et de développement économiques and published by . This book was released on 2012 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cost estimation for the decommissioning of nuclear facilities can vary considerably in format, content and practice both within and across countries. These differences may have legitimate reasons but make the process of reviewing estimates complicated and the estimates themselves difficult to defend. Hence, the joint initiative of the OECD Nuclear Energy Agency (NEA), the International Atomic Energy Agency (IAEA) and the European Commission (EC) was undertaken to propose a standard itemisation of decommissioning costs either directly for the production of cost estimates or for mapping estimates onto a standard, common structure for purposes of comparison. This report updates the earlier itemisation published in 1999 and takes into account experience accumulated thus far. The revised cost itemisation structure has sought to ensure that all costs within the planned scope of a decommissioning project may be reflected. The report also provides general guidance on developing a decommissioning cost estimate, including detailed advice on using the structure.
Book Synopsis An Analysis of Decommissioning Costs for the AFRRI TRIGA Reactor Facility by :
Download or read book An Analysis of Decommissioning Costs for the AFRRI TRIGA Reactor Facility written by and published by . This book was released on 1989 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides a cost analysis for decommissioning the Armed Forces Radiobiology Research Institute (AFRRI) TRIGA reactor facility. AFRRI is not suggesting that the AFRRI TRIGA reactor facility be decommissioned. This report was prepared in compliance with paragraph 50.33 of Title 10, Code of Federal Regulations, which requires that funding for the decommissioning of reactor facilities be available when licensed activities cease. The planned method of decommissioning is complete decontamination (DECON) of the AFRRI TRIGA reactor site to allow for restoration of the site to full public access. The cost of DECON in 1990 dollars is estimated to be $3,200,000. The anticipated ancillary costs of facility site demobilization and spent fuel shipment will be an additional $600,000. Thus, the total cost of terminating reactor operations at AFRRI will be about $3,800,000. The primary basis for developing this cost estimate was a study of the decommissioning costs of similar reactor facility performed by Battelle Pacific Northwest Laboratory, as provided in U.S. Nuclear Regulatory Commission publication NUREG/CR-1756. The data in this study were adapted to reflect the decommissioning requirements of the AFRRI TRIGA reactor facility.

Book Synopsis Costs of Decommissioning Nuclear Power Plants by :
Download or read book Costs of Decommissioning Nuclear Power Plants written by and published by . This book was released on 2016 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: While refurbishments for the long-term operation of nuclear power plants and for the lifetime extension of such plants have been widely pursued in recent years, the number of plants to be decommissioned is nonetheless expected to increase in future, particularly in the United States and Europe. It is thus important to understand the costs of decommissioning so as to develop coherent and cost-effective strategies, realistic cost estimates based on decommissioning plans from the outset of operations and mechanisms to ensure that future decommissioning expenses can be adequately covered. This study presents the results of an NEA review of the costs of decommissioning nuclear power plants and of overall funding practices adopted across NEA member countries. The study is based on the results of this NEA questionnaire, on actual decommissioning costs or estimates, and on plans for the establishment and management of decommissioning funds. Case studies are included to provide insight into decommissioning practices in a number of countries.

Book Synopsis An Investigation of Major Component Disposal Costs for Advanced Nuclear Reactors by : Chumani Mokoena
Download or read book An Investigation of Major Component Disposal Costs for Advanced Nuclear Reactors written by Chumani Mokoena and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Waste disposal is an important aspect for decommissioning of Nuclear Power Plants (NPPs) that requires an understanding of the characteristics of the waste forms. The costs of disposal depend on the activity, volume, dose rate and waste handling/packaging. The U.S. average nuclear reactor age is 40 years old, with many pursuing license extensions. Decommissioning costs are several hundred million dollars, with waste disposal alone predicted to cost over $100 million by the U.S. Nuclear Regulatory Commission (NRC). The current NPP fleet is exclusively made of light water reactors and as such there are no detailed study of decommissioning for advanced reactors that are being developed for deployment. This work modelled activity and benchmarked the disposal costs for a Pressurized Water Reactor's (PWR) components (core shroud, barrel and reactor pressure vessel) against previous work funded by the NRC. The same methodology was then applied towards characterizing disposal costs for a Molten Salt Reactor. Both a crude analytical method that is accessible to the general community and more detailed numerical method with MCNPX and CINDER90 were used to estimate the activity of the reactor vessel and its internals. Disposal costs are based on the Texas Low Level Waste (LLW) facility. Generally, the analytical method overestimated the flux and/or activity of components closer to the core such as the core barrel (PWR) or MSR internals. However, the waste classification was consistent for both methods. The nuclides contributing to the long-term activity of the components throughout the study were Ni-59, Co-60 and Ni-63, while the nuclides with a half-life less than five-years dominated the initial total activity. The PWR core shroud, barrel and vessel were designated as greater than Class C, Class C and Class A, respectively. Based on the disposal costs of the PWR components analyzed, the levelized cost of disposal for a PWR was scaled to be $0.68-$0.9/MWh assuming a 40-year operating lifetime, below the $1/MWh that is typically budgeted. The MSR analysis focused on the activity and disposal costs of the graphite reflectors, core can/shroud, and reactor vessel. Metal components were modelled as either SS316 or Hastelloy N based with an operating period of 5 to 10 years. Graphite reflectors were Class C waste with a specific disposal cost of about $2,200/kg. The core can was greater than Class C waste for both Hastelloy N and SS316. The vessel was Class C for SS316 (5-10 years) and Class C for Hastelloy N (5-7 years) before becoming greater than Class C waste for a 10-year operating lifetime. MSR disposal costs were computed with and without a PWR activation charge limits assuming both an immediate disposal (high cost) and disposal after a 20-year decay period after plant shutdown (low cost). Without activation cost limits, the total levelized cost of disposal is $8.27 to an enormous $779/MWh but the range reduces to $7.25-$20.10/MWh if limits on activation charge are imposed. In all scenarios, the MSR disposal of the reactor vessel and its internals alone were larger than $1/MWh commonly assumed for light water reactors. In addition, the noted cost does not include increased scope for fueled-salt cleanup and decontamination of the considered components as well as primary piping and heat exchangers. Therefore, this work motivates advanced reactor developers, particularly, the MSR community, to estimate the disposal cost of their technologies as it may play an important role in their economic viability.
Book Synopsis Technology, Safety and Costs of Decommissioning a Reference Boiling Water Reactor Power Station by :
Download or read book Technology, Safety and Costs of Decommissioning a Reference Boiling Water Reactor Power Station written by and published by . This book was released on 1990 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study presents the results of a comparison of a previous decommissioning cost study by Pacific Northwest Laboratory (PNL) and a recent decommissioning cost study of TLG Engineering, Inc., for the same commercial nuclear power reactor station. The purpose of this comparative analysis on the same plant is to determine the reasons why subsequent estimates for similar plants by others were significantly higher in cost and external occupational radiation exposure (ORE) than the PNL study. The primary purpose of the original study by PNL (NUREG/CR-0672) was to provide information on the available technology, the safety considerations, and the probable costs and ORE for the decommissioning of a large boiling water reactor (BWR) power station at the end of its operating life. This information was intended for use as background data and bases in the modification of existing regulations and in the development of new regulations pertaining to decommissioning activities. It was also intended for use by utilities in planning for the decommissioning of their nuclear power stations. The TLG study, initiated in 1987 and completed in 1989, was for the same plant, Washington Public Supply System's Unit 2 (WNP-2), that PNL used as its reference plant in its 1980 decommissioning study. Areas of agreement and disagreement are identified, and reasons for the areas of disagreement are discussed. 31 refs., 3 figs., 22 tabs.
Book Synopsis Costing Methods and Funding Schemes for Radioactive Waste Disposal Programmes by : IAEA
Download or read book Costing Methods and Funding Schemes for Radioactive Waste Disposal Programmes written by IAEA and published by International Atomic Energy Agency. This book was released on 2020-11-11 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 programmes costs.
