Why should safeguards by design be a global effort?
Jeremy Whitlock
I can’t think of a more exciting time to be working in nuclear, with the diversity of advanced reactor development and increasing global support for nuclear in sustainable energy planning. But we can’t lose sight of the need to plan for efficient international safeguards at the same time.
Global nuclear deployment has been underpinned since 1970 by the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), making it a key customer requirement for governments to demonstrate unequivocally that the technology is not being misused for weapons development.
The International Atomic Energy Agency (IAEA) has helped verify this commitment for more than 50 years, but it has never safeguarded many of the advanced reactors (and related fuel cycle processes) being developed today.

The assessment and control of image quality is a fundamental task associated with good practice to guarantee a suitable diagnosis by the radiologist. The need for image quality assessments in radiography is well established, and the use of test phantoms is a common method for this purpose. In this work we present a developed tool that consists of a specific phantom (named RACON) that is used for acceptance and constancy test in order to analyze the image obtained by digital radiographic equipment, software (named SoftRACON) for automated image analysis with digital processing techniques, and a database to store test phantom images and the scoring results.The main objective is to characterize the constancy of the radiographic imaging chain and guarantee acceptable image quality, related to well-functioning of the radiographic equipment. Therefore, the application presented in this work is sensitive enough to the operating conditions of the radiographic digital equipment and allows the assessment of the imaging system quality and, consequently, increases the objectivity (accuracy) in the evaluation of the image.
