Tering Distributions Using MCNP Simulations of Critical Measurements and Simplified Calculation Benchmarks K.S
International Conference on Nuclear Data for Science and Technology 2007 DOI: Assessment of evaluated (n,d) energy-angle elastic scat- tering distributions using MCNP simulations of critical measurements and simplified calculation benchmarks K.S. Kozier Atomic Energy of Canada Limited, Chalk River Laboratories, Chalk River, Ontario, Canada, K0J 1J0 Abstract. Different evaluated (n,d) energy-angle elastic scattering distributions produce k-effective differences in MCNP5 simulations of critical experiments involving heavy water (D2O) of sufficient magnitude to suggest a need for new (n,d) scattering measurements and/or distributions derived from modern theoretical nuclear models, especially at neutron energies below a few MeV. The present work focuses on the small reactivity change of <1 mk that is observed in the MCNP5 D2O coolant-void-reactivity calculation bias for simulations of two pairs of critical experiments performed in the ZED-2 reactor at the Chalk River Laboratories when different nuclear data libraries are used for deuterium. The deuterium data libraries tested include ENDF/B-VII.0, ENDF/B-VI.4, JENDL-3.3 and a new evaluation, labelled Bonn-B, which is based on recent theoretical nuclear-model calculations. Comparison calculations were also performed for a simplified, two-region, spherical model having an inner, 250-cm radius, homogeneous sphere of UO2, without and with deuterium, and an outer 20-cm-thick deuterium reflector. 1 Introduction The present work focuses on the sensitivity of the ZED-2 MCNP5 CVR calculation bias to -

Schruder, Waste Remediation & Enhancement Projects Division D. Wilder, Site Engineering & Project Management Division W. Graham, Components & Systems Division AECL, Chalk River Laboratories, MS #E4 Chalk River, ON, Canada K0J 1J0 [email protected] ABSTRACT Liquid intermediate- and high-level radioactive wastes presently stored in 21 tanks at the Chalk River Laboratories are being retrieved, conditioned and consolidated into a new storage system. The Liquid Waste Transfer and Storage project is responsible for designing, constructing and commissioning the storage system, specifying and procuring retrieval and transfer equipment and developing operating, maintenance and training procedures and materials. The project has characterized the existing wastes and completed an inspection of the present storage tanks and vaults. The conceptual design has progressed to include a criticality safety assessment, a safeguards analysis, selection of retrieval and transfer technologies and conceptual design of the new storage system. The transfer and collection of wastes from these 21 tanks will be a step forward in the goal of achieving a long-term management solution for the wastes. This paper provides an overview of the development of the conceptual design, including the new storage system, the retrieval system and the transfer systems, the laboratory program that supports the blending sequence and waste conditioning and the tank and vault inspection. INTRODUCTION Atomic Energy of Canada Limited (AECL) is a Federal Crown Corporation charged with leading the development of peaceful applications of nuclear technology in Canada. -

Decommissioning Projects at the Chalk River Laboratories Over the Next 5 Years and the Challenges with Delivery
Waste Management, Decommissioning and Environmental Restoration for Canada’s Nuclear Activities September 11-14, 2011 CW -508300-CONF-003 UNRESTRICTED DECOMMISSIONING PROJECTS AT THE CHALK RIVER LABORATORIES OVER THE NEXT 5 YEARS AND THE CHALLENGES WITH DELIVERY K. Schruder, J. McKenna and A. Winter Atomic Energy of Canada Limited, Chalk River Laboratories Chalk River, Ontario, Canada ABSTRACT Nuclear research and development carried out on behalf of the Government of Canada have resulted in 60 years of nuclear legacy liabilities at the Chalk River Laboratories. The liabilities consist of shutdown reactors, research facilities and supporting infrastructure. The Government of Canada in 2006 initiated a five-year, $520 million start-up phase and in April 2011 entered the next 5-year program of decommissioning as part of the long term strategy to address the legacy liabilities. A number of planned projects in Facilities Decommissioning, at the Chalk River Laboratories, have been defined for the next 3 years and will be described in this paper in combination with operational lessons learned for future decommissioning project work. 1. INTRODUCTION The Chalk River Laboratories (CRL) is the Canadian nuclear research facility located near Chalk River, Ontario, approximately 180 km north-west of Ottawa, on the Trans-Canada Highway. CRL is a site of major research and development to support and advance nuclear technology. CRL has expertise in physics, metallurgy, chemistry, biology, and engineering and consists of both operating and shutdown unique research facilities. CRL was conceived in 1942 from collaboration between British and Canadian nuclear researchers, where a research laboratory established in Montreal under the National Research Council of Canada (NRC). -

En plus de son utilisation actuelle principale pour la production d'électricité, et, à un degré moindre, la propulsion marine, l'énergie nucléaire a été et peut être utilisée pour les applications de chaleur industrielle, comme le chauffage des locaux, le chauffage industriel et le dessalement de l'eau de mer. En outre, une grande variété de types de réacteurs a été employée à cette fin dans divers pays. En se fondant sur cette expérience, deux méthodes de conception surgissent pour le chauffage industriel nucléaire : extraction d'une partie de l'énergie thermique d'une centrale nucléaire (c.-à-d. -
