Dominique Finon Carine Staropoli* Among the various traditional "grands programmes" typical of the French public intervention in high-tech industries, the nuclear programme is often considered as one of the major successes. About 60 nuclear reactors have been built between 1970 and 1998. Altogether they generate 80% of the electricity produced by the state-owned monopoly at a competitive cost. Moreover, the French nuclear industry ranks first on the world market of nuclear equipment and services. Such performances are all the more contrasting with those in the other OECD countries, where costs have dramatically increased while many projects never went ahead: since the 1980s a number of electricity companies decided to stop their riskyinvestments in nuclear equipment in many countries. Such a performance is attributable to an appropriate institutional set-up, which has been able to enforce all the technological leaming needed to the implementation of this kind of radical complex and large-sized innovation.

Dissemination Level PU Public X RE Restricted to the partners of the CAST project CO Confidential, only for specific distribution list defined on this document CAST WP5 Review of Current Understanding of Inventory and Release of C14 from Irradiated Graphite (D5.5) CAST – Project Overview The CAST project (CArbon-14 Source Term) aims to develop understanding of the potential release mechanisms of carbon-14 from radioactive waste materials under conditions relevant to waste packaging and disposal to underground geological disposal facilities. The project focuses on the release of carbon-14 as dissolved and gaseous species from irradiated metals (steels, Zircaloys), irradiated graphite and from ion-exchange materials. The CAST consortium brings together 33 partners with a range of skills and competencies in the management of radioactive wastes containing carbon-14, geological disposal research, safety case development and experimental work on gas generation. The consortium consists of national waste management organisations, research institutes, universities and commercial organisations. The objectives of the CAST project are to gain new scientific understanding of the rate of release of carbon-14 from the corrosion of irradiated steels and Zircaloys and from the leaching of ion-exchange resins and irradiated graphites under geological disposal conditions, its speciation and how these relate to carbon-14 inventory and aqueous conditions.

  • NRC Regulatory History of Non-Light Water Reactors (1950-2019)
    BNL-211739-2019-INRE NRC Regulatory History of Non-Light Water Reactors (1950-2019) Manuscript Completed: June 10, 2019 Prepared by: Pranab Samanta, David Diamond, and William Horak Nuclear Science and Technology Department Brookhaven National Laboratory Upton, NY 11973-5000 Prepared for: Imtiaz Madni and George Tartal Office of New Reactors U.S. Nuclear Regulatory Commission ABSTRACT This report describes the U.S. Nuclear Regulatory Commission’s (NRC’s) history with the licensing of non-light water reactors (non-LWRs). The focus is on regulatory policy and licensing issues that have arisen in the past so that NRC staff will be in a better position to deal with these matters in the future. It is not an objective to discuss in any detail the technology of non-LWR designs. Documenting the historical policy issues and licensing approaches is particularly important to NRC staff unfamiliar with non- LWRs and is an important incentive for the report. Hence, the report is written as a tutorial rather than as an historical archive. The subject is approached chronologically going from the early days of the Atomic Energy Commission to the formation of the NRC, then into the era when the regulatory structure newly developed for LWRs provided guidance for other types of reactors, followed by the era when policy was made specifically for advanced reactors including non-LWRs. This background provides the transition to current planning for future non-LWR licensing and policy─also described herein. iii TABLE OF CONTENTS ACRONYMS ...................................................................................................................vi 1 INTRODUCTION ................................................................................................... 1-1 1.1 Background ............................................................................................... 1-1 1.2 Objective ..................................................................................................

  • The Amster Concept (Actinides Molten Salt Transmuter)
    1 THE AMSTER CONCEPT (ACTINIDES MOLTEN SALT TRANSMUTER) J VERGNES P. BARBRAULT,D LECARPENTIER, Ph TETART EDF Pole Industrie Division Recherche et Développement Département Physique des Réacteurs 1 Avenue du Général de Gaule 92140 CLAMART France e mail: jean.vergnes@edfgdf;fr H MOUNEY EDF Pole Industrie Division Ingéniérie et Services CAP AMPERE 93282 SAINT DENIS CEDEX France e mail: henri.mouney@edfgdf;fr ABSTRACT In the frame of the French law related to the management of long lived radioactive wastes, a reactor concept aiming both to generate electricity and to minimize existing transuranics (TRU) and long lived fission product is proposed. This concept named AMSTER is a Molten Salt Reactor, the molten fuel being a mixing of Transuranics and enriched Uranium. The salt processing is integrated and allows both to supply U-235 and to separate fission products while minimizing transuranics losses. Two options have been analyzed : · a TRU self-burning option, releasing only a few grams/Twhe of TRU in the wastes for geological storage. It needs an equilibrium inventory of 1.6 metric tons/Twhe in the reactor and a consumption of 10 metric tons/Twhe of natural uranium (compared to 21 for PWR) ; · a TRU incineration option which would permit, for example to burn the TRU present in PWR spent fuels at a rate of 28 kg/TWhe, for an inventory at equilibrium of 4.7 metric tons/Twhe of TRU. The consumption would be then of 2.2 metric ton/TWhe of PWR spent fuel and 3.7 metric ton/TWhe of natural Uranium. 2 1.
