[en] In 1969 CRNL recognized the need for a strong group skilled in non-destructive test procedures. Within two years a new branch called Quality Control Branch was staffed and working. This branch engages in all aspects of non-destructive testing including development of new techniques, new applications of known technology, and special problems in support of operating reactors.

[en] The scientific life of Wilfrid Bennett Lewis. The biography covers Lewis's role in the development of radar, his tenure as the Chief Superintendent of the Telecommunications Research Establishment at Malvern through his heading of the then fledgling Canadian nuclear research facility in Chalk River, Ontario. Lewis's drive, intelligence, and remarkable organizational skills placed him at the forefront of Canada's nuclear program. His influence lead to a collaboration between Atomic Energy of Canada Limited and Ontario Hydro that ultimately resulted in the development of the CANDU reactor. His influence was also profound in the near by town of Deep River with one prime legacy being the W.B. Lewis Library. Lewis's bibliography is included in the biography

[en] A list of 1900 serial publications (periodicals, society transactions and proceedings, annuals and directories, indexes, newspapers, etc.) is presented with volumes and years held by the Main Library. This library is the largest in AECL as well as one of the largest scientific and technical libraries in North America, and functions as a Canadian resource for nuclear information. A main alphabetical list is followed by broad subject field lists representing research interests, and lists of abstract and index serials, general bibliographic serials, conference indexes, press releases, English translations, and original language journals

[en] The Chalk River Nuclear Laboratories (CRNL) are located in a sparsely populated area on the Ontario bank of the Ottawa River, approximately 150 km upstream from Ottawa. The site contains diverse facilities including research reactors, research laboratories and support facilities, isotope production facilities, a heavy-water upgrading plant and waste management areas. Due to the nature of operations at CRNL, the range of radionuclides potentially or actually released to the environment is greater than that in normal releases from operating power reactors. The monitoring program for routine releases (which are much below prescribed limits) at CRNL has evolved over many years and it has been designed to measure adequately the releases of radionuclides and assess their concentrations along environmental pathways. The major effluent streams from CRNL are sampled continuously with automatic samplers. These samples are analysed for total beta and gross alpha activities, while composite samples are analysed for specific radionuclides by liquid scintillation counting, gamma-ray spectrometry and radiochemical analysis. Releases from the waste management areas are monitored by routine sampling of surface waters on site. Groundwater and subsurface sediment samples are collected periodically to map active plumes and to provide data for research studies. The off-site effects of airborne releases are monitored with a network of TLD's. Monthly composite samples from the Ottawa River are collected both upstream and downstream of CRNL, while other offsite surface waters are sampled annually. The concentrations of radionuclides in precipitation and local milk are also routinely measured. Routine meteorological measurements are also included in the monitoring program at CRNL. The data are used to calculate doses from airborne releases under both normal and accident conditions

[en] The innovation process introduced into AECL's research laboratories is described, with its achievements in increased commercial and spin-off businesses. In particular, the role of the champion or entrepreneur is emphasized in the manner in which he/she interacts within a dedicated team to pursue each opportunity. Examples are provided of several commercial and business development opportunities resulting from the background research programs

[en] The history of the NRX reactor is briefly recounted. When NRX started up in 1947, it was the most powerful neutron source in the world. It is now the oldest research reactor still operating. NRX had to be rebuilt after an accident in 1952, and its calandria was changed again in 1970. Loops in NRX were used to test fuel for the Nautilus submarine, and the first zircaloy pressure tube in the world. At the present time, NRX is in a 'hot standby' condition as a backup to the NRU reactor, which is used mainly for isotope production. NRX will be decommissioned after completion and startup of the new MAPLE-X reactor

[en] The Seminar for Labour on the Objectives and Work of CRNL was held in Chalk River, Ontario, Canada on May 29-31, 1972. The main objective is to review the work and contributions of employees at Chalk River Nuclear Laboratories. Three specific matters communicated at the conference are: a full sense of pride in the achievements the employees have helped to bring about; a realization that CRNL has a long future ahead of it and though much as been accomplished, much more remains to be done; and, that Chalk River is a good place to work and there is a high regard for the safety of every employee. Not all aspects of work done at CRNL could be presented, however the selected samples cover a fairly large spectrum of the functions in the Laboratories. This document provides the opportunity to determine just how large and essential a role the employees and the Laboratory has played and will continue to play in Canadian and world wide affairs.
