A Company-wide Activity to Grow Safety Culture in A Maintenance Department of Nuclear Power Plant

摘要

This study aims to conduct a field survey to collect specific instances of "learning activity" that would help develop a safety culture in a maintenance department of nuclear power plant, with "activity theory" as a theoretical base, and to derive a conceptual model that portrays these instances as part of comprehensive organizational activities. First, the field survey found instances where an accident that occurred a few years ago provided momentum;a company-wide activity is being implemented in order to fulfill the requests of field workers so that their requests for improvements are positively honored and budgets are allocated to measures designed to accommodate these requests. This paper calls this company-wide activity "an activity to materialize the requests for improvements in the workplace" and considers it to be a typical instance of learning activity. Second, the field survey found that, in the workplace under discussion, a daily meeting was held in a unique way and a study session was conducted frequently and regularly. Last, we came up with a conceptual model for the entire aspect of organizational activities in which we could position the above instances as well as the results of our past field surveys. This model conceptualizes organizational activities from the two aspects of "learning activity (primary learning activity)" and "management activity" and characterizes an activity that would transform the existing organizational activities into ones that could not be even predicted as "secondary learning activity. " "An activity to materialize the requests for improvements in the workplace" was taken as falling under the category of secondary learning activity.
