DOE 2011 Occupational Radiation Exposure report, _Prepared for the U.S. Department of Energy, Office of Health, Safety and Security. December 2012

Abstract

Foreword Foreword ForewordA core value of the U.S. Department of Energy (DOE) is to ensure the health and safety of DOE employees, contractors, and subcontractors. The Office of Health, Safety and Security (HSS) provides the corporate-level leadership and strategic vision necessary to establish clear expectations for, and provide oversight and enforcement regarding health, safety, environment, and security programs. In support of this mission, the HSS Office of Analysis provides for the collection, analysis, and dissemination of data and performance indicators, such as occupational radiation exposure information.A key safety focus for DOE is to maintain worker radiation exposures below administrative control levels (ACL) and DOE radiation dose limits and to further reduce these exposures to levels that are "as low as reasonably achievable (ALARA)." The annual DOE 2011 Occupational Radiation Exposure Report provides an evaluation of DOE-wide performance regarding compliance with Title 10, Code of Federal Regulations, Part 835, Occupational Radiation Protection dose limits and ALARA process requirements and an overview of the status of radiation exposures of the DOE workforce. In addition, this report serves as a risk management tool for managing radiological safety programs and provides useful information to DOE organizations, epidemiologists, researchers, and national and international agencies involved in developing policies to protect individuals from harmful effects of radiation.The Radiation Exposure Monitoring System (REMS) program remains a key component of HSS oversight and analysis to inform management and stakeholders of the continued vigilance and success of the DOE sites in minimizing radiation exposure to workers. One of the objectives of this report is to provide useful, accurate, and complete information to DOE and the public. As part of a continuing improvement process, we would appreciate your response to the User Survey included at the end of this report. iv DOE 2011 Occupational Radiation Exposure ReportThis page intentionally left blank. (ALARA) process requirements. In addition, the report provides data to DOE organizations responsible for developing policies for protection of individuals from the adverse health effects of radiation. The report provides a summary and an analysis of occupational radiation exposure information from the monitoring of individuals involved in DOE activities. The occupational radiation exposure information is analyzed in terms of aggregate data, dose to individuals, and dose by site over the past five years.It should be noted that was revised as of June 2007, with full implementation required by July 2010. All sites have now transitioned, and therefore this report reflects the changes in dose terminology and dose assessment methodology required by the revision to 10 C.F.R. 835.As an indicator of the overall amount of radiation dose received during the conduct of operations at DOE, the report includes information on collective total effective dose (TED).

Robot-Assisted Glovebox Teleoperation for Nuclear Industry

“…Autonomous robotics and teleoperation are also key factors to innovate the dismantling of legacy gloveboxes in multiple nuclear facilities in the world. Up to now, operators have accomplished different tasks by inserting their hand (with proper equipment) into a hazardous environment where the consequence of an accident could be serious: The operator could be contaminated by accidental cuts of the rubber glove [13] or by an error in the operation process [14]. Robotics and artificial intelligence can be profitably used to remove the operator from these dangerous tasks while autonomous or semi-autonomous systems could accomplish the activities.…”

“…Autonomous robot and tele-operation are also key factors to innovate a legacy glovebox that is going to be dismantled in multiple nuclear facilities in the world. Up to now, operators accomplish different tasks by inserting the hand (with proper equipment) in a hazardous environment where the consequence of an accident could be serious: the operator could be contaminated by accidental cuts of the rubber glove [5] or by an error in operation process [6].
