Petrunik KEPCO AECL CANDU KEPCO with the support of AECL and other Korean and Canadian subcontractors has created a strong multi-company team to execute design and construction of the Wolsong 2 CANDU 6 power plant. Key concepts of the project team are: 1. KEPCO is the project manager and AECL is the Engineering Contractor. 2. Significant participation by Korean companies in design work in Canada and Korea. 3. Significant manufacturing in both Canada and Korea. 4. Construction by Korean contractors. Key concepts of the Wolsong 2 design are: 1. Evolutionary improvement of the Wolsong 1 plant which balances proven technology and necessary design improvements including current codes and standards. 2. Sharing of some structures with the Wolsong 1 plant. This paper describes the successful establishment and operation of the complex project interfaces along with the current project status and plans. 920068/dp/transfer/cna/wp51 1992/05/11 UPDATE ON CANADA'S WASTE MANAGEMENT PROGRAM C.J. Allan Vice-President, Environmental Sciences and Waste Management AECL Research Pinawa, Manitoba ROE 1L0 204-753-2311 The Canadian Nuclear Fuel Waste Management Program (CNFWMP) was launched in 1978 as a joint initiative by the Governments of Canada and Ontario. Under the program AECL has been developing and assessing a concept to dispose of nuclear fuel wastes in plutonic rock, of the Canadian Shield. Ontario Hydro has advanced the technologies for interim storage and transportation of used fuel- In 1981 the two Governments stated that selection of a nuclear fuel waste disposal site would not proceed until the concept had been reviewed and assessed. Thus the concept that has been developed is generic rather than site-specific. In common with programs in other countries the Canadian concept is to isolate the fuel waste from the biosphere by a series of engineered and natural barriers. These include the waste form, container, buffer and backfill materials, and the host rock. During the past fourteen years AECL has carried out detailed studies on each component of this barrier system. A concept has been developed with options for the choice of materials and designs for the different components. The Underground Research Laboratory (URL) is playing an important role in our program. Construction of this facility was completed early in 1990. The shaft extends to 443 metres below the surface, and experimental rooms have been built at the 240 and 420 metre levels. The URL has now entered the operating phase. The planned program of experiments include: 1) Investigations of solute transport in highly and moderately fractured rock, 2) The Buffer-Container Experiment, a demonstration of the engineering aspects of borehole emplacement, 3) The Mine-by Experiment, a study of the mechanical properties and response of an intact volume of highly stressed rock to excavation, 4) An engineering demonstration of the grouting of a fracture zone, 5) A study of materials and emplacement methods for shaft sealing, and 6) A large-scale integrated multicomponent experiment to study buffer emplacement and room backfilling and sealing, and to provide a database on the performance of a fully backfilled room. The first phase of the full-scale Buffer-Container Experiment has been started. An electrically-heated simulated used fuel container has been emplaced in an in-floor borehole excavated in intact granite. In a first experiment, expected to last about one year, water uptake by the buffer material will be controlled by the permeability of the rock. In a second experiment, which will last about two years, a constant supply of groundwater from the URL will L fed to the buffer-rock interface. In the Mine-by Experiment we are monitoring the response of a highly-stressed rock mass to excavation using a variety of techniques, e.g., micro-seismic detectors and ultrasonic tomography. The response will be compared to predictions obtained with our rock mechanics codes. The disposal concept has been referred for review under the Canadian Environmental Assessment and Review Process (EARP). AECL is the "Proponent" for this review, and will submit an Environmental Impact Statement (EIS) describing the concept. The EIS will be written to conform with guidelines issued by the Environmental Assessment Panel responsible for carrying out the review. Once the EIS has been submitted public hearings will be held at which members of the public will have an opportunity to make presentations to the Panel and to question AECL. The hearings will take place in those provinces with a particular interest in the concept and its application, including Ontario, Quebec, New Brunswick, Manitoba and Saskatchewan. At the end of the review the Panel will make recommendations on the acceptability of the concept and for future action on nuclear fuel waste disposal. Government decisions are then anticipated on the next steps to be taken. The Panel conducting this review was appointed in late 1989. Public Houses were held in the spring of 1990 to acquaint prospective participants with the process. Scoping Sessions to assist the Panel in determining the scope of the EIS took place in the autumn of 1990. In 1991 June the Panel issued, for comment, draft guidelines for the EIS. Comments were received from over 30 different groups and individuals. The final guidelines were issued in 1992 March. It is anticipated that AECL will submit its EIS to the Panel in 1993. Social and ethical issues associated with the management of nuclear fuel wastes were of considerable concern to participants in the Scoping Sessions. In March 1991 AECL conducted a workshop to provide perspectives on the key ethical issues related to the concept, and to obtain advice on approaches to addressing the issues identified. A report summarizing the proceedings of the workshop has been produced. The future direction of the CNFWM program will depend on the recommendations of the Panel and the subsequent governmental decisions on the appropriate next steps. AECL and Ontario Hydro have, however, initiated planning to be in a position to proceed with implementation if the disposal concept is approved. If the concept review is completed by 1995, as currently scheduled, and if the concept is approved, disposal could not begin before about 2025. NEW BRUNSWICK'S EXPERIENCE WITH CITIZENS GROUPS R. E. Tweeddale Prince William, NB, EOH ISO 506-363-2494 In response to the Brundtland Report, a "Premier's Round Table on Environ- ment and Economy" was established in New Brunswick in 1988 to conduct public hearings. Its mandate was to examine the environmental and economic problems within distinct segments of the provincial economy (e.g., agriculture, energy, education, etc.) and to suggest appropriate strategies to reduce conflicts between economic growth and the welfare of the environment. A broadly based but very informal group of citizens in Fredericton came into being to study and critique the work of the Premier's Round Table. Its mem- bers felt that "loud and emotional voices" were tending to warp the Round Table's agenda. Insofar as the production of electrical energy is concerned, the group felt that the preferred direction for future development in New Brunswick was nuclear. Their dominant reason for this choice was that it believed that it was environ- mentally the least risky. A secondary reason was that this choice would be highly beneficial to the provincial economy.

It is intended to provide an overall review on the production, accumulation and projections of radioactive waste in Canada. The data presented in this report has been gathered from many sources including regulatory documents, published reports and supplemental information provided by the nuclear regulator, waste producers and waste management facilities. Radioactive waste has been produced in Canada since the early 1930s when the first radium mine began operating at Port Radium in the Northwest Territories. Radium was refined for medical use and uranium was later processed at Port Hope, Ontario. Research and development on the application of nuclear energy to produce electricity began in the 1940s at the Chalk River Laboratories (CRL) of Atomic Energy of Canada Limited (AECL). At present, radioactive waste is generated in Canada from: uranium mining, milling, refining and conversion; nuclear fuel fabrication; nuclear reactor operations; nuclear research; and radioisotope manufacture and use. Radioactive waste is primarily grouped into three categories: nuclear fuel waste, low- and intermediate-level radioactive waste, and uranium mining and milling waste. In accordance with Canada’s Radioactive Waste Policy Framework, the owners of radioactive waste are responsible for the funding, organization, management and operation of long-term waste management facilities required for their waste.

LidStone AECL Research Whiteshell Laboratories Pinava, Manitoba, Canada ABSTRACT ARCL Is currently building the 10-MV APLE-XIO reactor at the Chalk River Laboratories to operate as a dedicated producer of commerclal-scale quantities of key medical and ndustrial radioisotopes and as a demonstration of the MAPL.R reactor design. In support of the safety and licensing analyses, static physics calculations have been performed to determine the neutronic performance and safety characteristics of the APLE-XIO reactor. This report summarizes results from the static physics calculations for several core conditions prior to commencing radioisotope production. 1. INTRODUCTION Atomic Energy of Canada Limited (AECL) is currently undertaking a Research Reactor Rationalization Program [1) hich ill define AECL's research reactor capabilities for the next ten to fifteen years. This rationalization program has been initiated to address several issues: 1. AECL's current research reactors, NRX and NRU, have operated for 44 and 34 years respectively. These reactors are ageing and are in need of rehabilitation or replacement. 2. There is a growing demand for radioisotopes hich has increased the number of radioisotope targets installed in the prime irradiation space in the NRU and NRX reactors. 3. The CANDU power reactor has achieved a successful operating and maintenance record and the demands for supporting research have changed significantly. 1. These authors are located at the Chalk River Laboratories, Chalk River, Ontario, Canada. 271 One major step in the rationalization program has been to develop the MAPLE reactor 12,3] to meet contemporary Canadian and international requirements for modest-cost, ultipurpose neutron sources.
