The George B. Pegram Lecturer for 1962 is Professor Derek J. de Solla Price of Yale University, who is an eminent historian of science.

Using these reactors and accelerators, fundamental and applied research and develop- ment is carried out in physics, metallurgy, biology, medicine, chemistry and engineering. Canada was one of the pioneers in the application of radioactive isotopes in research, medicine, agriculture and industry. The Commercial Products Divi- sion of the AECL processes and sells radioactive isotopes produced in the Chalk River reactors and also develops new uses for isotopes and equipment for their application. It is the policy of AECL to contract out to industry as much of the development work on nuclear power as is practical. However, much of the work, particularly fuel development, depends on access to irradi- ation facilities that are only available at Chalk River. Industry, therefore, works closely with the Chalk River staff. A reactor school has beer1 established at Chalk River to give both Canadian and foreign scientists alnd engineers intensive twelve-week courses that emphasize the type of research reactors and atomic power stations devel- oped in Canada. Students and some university staff members are employed for summer work, visits are arranged for groups of students at all levels, and talks and lectures by Chalk River scientists are given at a variety of gatherings from school groups through service clubs to highly technical meetings.

    309 IAEA-SM-310/ 94 SAFETY RE-ASSESSMENT OF AECL TEST AND RESEARCH REACTORS D. J. WINFIELD Chalk River Nuclear Laboratories ATOMIC ENERGY OF CANADA LIMITED 310 IAEA-SM-310/94 SAFETY RE-ASSESSMENT OF AECL TEST AND RESEARCH REACTORS ABSTRACT Atomic Energy of Canada Limited currently has four operating engineering test/research reactors of various sizes and ages; a new isotope-production reactor MAPLE-X10, under construction at Chalk River Nuclear Laboratories (CRNL), and a heating demonstration/test reactor, SDR, undergoing high-power commissioning at Whiteshell Nuclear Research Establishment (WNRE). The company is also performing design studies of small reactors for hot water and electricity production. The older reactors are ZED-2, PTR, NRX and NRU; these range in age from 42 years (NRX) to 29 years (ZED-2). Since 1984, limited-scope safety re-assessments have been underway on three of these reactors (ZED-2, NRX and NRU). ZED-2 and PTR are operated by the Reactor Physics Branch, all other reactors are operated by the respective site Reactor Operations Branches. For the older reactors the original safety reports produced were entirely deterministic in nature and based on the design-basis accident concept. The limited scope safety re-assessments for these older reactors, carried out over the past 5 years, have comprised both quantitative probabilistic safety-assessment techniques, such as event tree and fault tree analysis, and/or qualitative techniques, such as failure mode and effect analysis. The technique used for an individual assessment was dependent upon the specific scope required. This paper discusses the types of analyses carried out, specific insights/recommendations resulting from the analysis and indicates the plan for future analysis.

ABSTRACT The bucklings of heavy water moderated lattices of ZEEP rods (3.25 cm diameter natural U metal contained in aluminum tubes) were measured by the flux mapping method in the ZED-2 reactor. The isotopic composition of trie moderator was 99.46 atom percent D2O. The bucklings, corrected for the 0.34 atom percent difference in isotopic composition, are in excellent ag.eement with earlier measurements made in the ZEEP reactor.

In this work, the neutronic models of these critical exper­ iments were investigated by TSUNAMI, a sensitivity and uncertainty (SjU) analysis tool, part of the SCALE6 reactor physics package from the Oak Ridge National Laboratory. TSUNAMI consists of different modules that are capable of calculating the values of keff and the uncertainties in keff due to uncertainties in the nu­ clear data. It generates energy-dependent sensitivity coefficients from which the percentage change in keff due to perturbations in nuclear data values can be determined. The calculated keff has a bias which is the difference between calculation and measurement.

    Fuels for Canadian Research Reactors

    XA04C1592 FUELS FOR CANADIAN RESEARCH REACTORS M. A. Feraday Atomic Energy of Canada, Ltd. Chalk River, Ontario INTRODUCTION Originallywhen I was requested to attend the meetingit was to be as an observer. Last Friday David Stahl asked if I would make an informal presenta- tion on the Canadian situation. The remarks I will make will be of a general -nature and should not necessarily be construed as official policy of AECL. They will be personal observations on several aspects of the program. Although my 22 years experience in the nuclear field ranges from reactor operations, fuel development, and now designing of remotely operated fuel plants for gamma active 233U-Th fuels, I am not expert in the fields of reactor physics, reactor safety, and the political implications of changing the enrichment in our two large research reactors. So what I would like to do this morning is: - say a few words on the uranium silicide fuels for which we have significant fabrication, irradiationand defect performance experience. - describe the two Canadian high flux research reactors which use high enrichment uranium (HEU) and the fuels currently used in these reactors. - comment on the limited fabrication work we are doing on Al-U alloys to uranium contents as high as 40 wt%. This work is aimed at our fast neutron program. I will then try and apply this experience in general terms to the NRX and NRU designs of fuel. U3Si PROGRAM For a period of about 10 years AECL had a significant program looking into the possibility of developing U3Si as a high density replacement for the U02 pellet fuel in use in CANDU power reactors.

Wilson iii ABSTRACT Title: Nuclear Fuel Waste Projections in Canada – 2020 Update Report No.: NWMO-TR-2020-06 Author(s): M. Gobien and M. Ion Company: Nuclear Waste Management Organization Date: October 2020 Abstract This report summarizes the existing inventory of used nuclear fuel wastes in Canada as of June 30, 2020 and forecasts the potential future nuclear fuel waste from the existing reactor fleet as well as from proposed new-build reactors. While the report focuses on power reactors, it also includes prototype, demonstration and research reactor fuel wastes held by AECL, which are included in the NWMO mandate. As of June 30, 2020, a total of approximately 3.0 million used CANDU fuel bundles (about 58,200 tonnes of heavy metal (t-HM)) were in storage at the reactor sites, an increase of about 90,250 bundles since the 2019 NWMO Nuclear Fuel Waste Projections report.
