Candu Energy Inc. (former commercial operation of AECL) has developed probabilistic tools to support nuclear plant operators with a risk-based fuel channel management strategy. One such tool is used to evaluate the probability of pressure tube rupture resulting from pressure tube to calandria tube contact and hydride blisters. This tool assumes that PT rupture occurs when delayed hydride cracking (DHC) initiates in a blister. The objectives of the probabilistic assessments are to: • Determine the overall risk of PT rupture in the reactor core for comparison with the acceptance criteria. • Determine the risk of PT rupture for specific fuel channels to assist in the development of an inspection/maintenance strategy. • Evaluate the risk reduction that would result from different fuel channels inspection/maintenance scenarios. • Optimize inspection/maintenance programs. The distributions of the most critical input distributions can be derived by benchmarking against in-reactor measurements. Two benchmark methods were developed to take advantage of the recent advancements in the accuracy of the inspection tool that measures the gap profile between the PT and the CT.

In modern conditions of increasing threats, challenges, dangers and threats of various types, it is necessary to create a system of innovative training of managers. The paper considers the formation of an innovation management strategy for education of managers on disaster risk reduction and the development of methodological support for this activity. In the course of work to achieve the goal, key tasks were solved: the organizational basis for the formation of an integrated education system was justified, proposals for creating an information and organizational learning innovation were developed, and the basis for a new unified innovative information and communication educational platform was created. Methodological recommendations for innovative training of managers are proposed. The research methodology provides for the creation of innovative and technological matrixes of Executive education based on modern methods of analysis and synthesis, expert assessments, modeling, analogies, and observation. The results of the research are the main provisions of the innovation management strategy for education of managers on disaster risk reduction, organizational and methodological support for this activity. On their basis, a comprehensive system of training managers has been created, and modern training programs and practices in the field of disaster management have been introduced. Recommendations for the consolidation of key modern achievements of science and technology in the educational sphere are formulated. The study may be of interest to state authorities in the formation and implementation of the state strategy of innovative management of education of managers, which provides a high modern level of training.

AbstractTall buttercup is an invasive forb that has been reported in all but eight states and one Canadian province. The species has been of concern in Montana where it has invaded over 8,300 ha, and it has been particularly problematic in irrigated hayfield meadows that are used for forage production. This study sought to develop an integrated management strategy to control tall buttercup while maintaining forage production. Research was conducted over 2 yr at flood-irrigated and subirrigated hayfield meadows near Twin Bridges, MT. Treatments were randomly applied in a split-plot design with four replications at both sites. Herbicide treatments occurred at the whole-plot level: nonsprayed, aminopyralid (172 g ai ha−1), aminocyclopyrachlor + chlorsulfuron (83 g ai ha−1+ 33 g ai ha−1), and dicamba (981 g ai ha−1). Split plots consisted of mowing and fertilization (28 kg N ha−1). All herbicides provided up to 2 yr of tall buttercup control at both sites. In the second year, aminocyclopyrachlor + chlorsulfuron and aminopyralid reduced tall buttercup by 93% and 96%, respectively, for the subirrigated and flood-irrigated sites. At the subirrigated site, mowing reduced tall buttercup by 71%, and fertilization reduced it by 57%. Forage decreased following aminocyclopyrachlor + chlorsulfuron treatments. The integration of herbicide, mowing, and fertilization did not improve tall buttercup control.
