Overview
Radiological safety analysis software is used to support licensing of nuclear facilities by modeling and assessing radiological consequences to workers and the public due to release of radioactivity to the environment. The software considers all aspects of radiological consequence assessments while adhering to nuclear standards such as the CSA N288 series of standards. The nuclear industry uses software like this to demonstrate compliance with radiological dose limits for human and non-human receptors set by regulatory bodies. Using such tools is essential for protecting workers, the public, and the environment while supporting nuclear facilities' safe and efficient operation.
Kinectrics developed this software suite to facilitate licensing of nuclear facilities. Leveraging decades of expertise in software development, maintenance, qualification, and analysis for nuclear applications, our tools are tailored to support a wide range of applications. ORCA (On/Off-site Radiological Consequences of Accidents) and RINO (Radiological Impacts of Normal Operations) are built to comply with stringent nuclear standards, including CSA N288, CSA N286.7 and NQA-1 (for ORCA). These analyses are vital for ensuring nuclear facilities' safety, compliance, and efficiency, providing insights to protect people and the environment while supporting seamless operations. By developing robust, user-friendly tools, Kinectrics is one of the leaders in radiological analysis solutions.

Radiological Safety Analysis Explained
Radiological safety analysis evaluates the radiological consequences to workers or members of the public from routine or accidental releases of radioactivity to the environment. Phenomena such as atmospheric turbulence, plume rise, stack and building downwash, radionuclide decay, dry deposition and washout are modeled to accurately predict the concentration of these materials in the environmental media (e.g., air, surface water, soil, plant and animal life) surrounding the nuclear facility. The dose consequences to an individual are then calculated by accounting for a variety of exposure pathways including inhalation, cloudshine, groundshine and ingestion, as appropriate. The results of the analysis are used to demonstrate compliance with dose limits set by the regulator.
Software Capabilities - ORCA
ORCA (On/Off-site Radiological Consequences of Accidents) calculates atmospheric dispersion and radiological doses following accidental airborne releases from nuclear facilities, following CSA Standard N288.2. The code supports calculations for facilities close to site boundaries (known as the near field) with the implementation of the dispersion parametrizations in NUREG/CR-6331, which is consistent with U.S. NRC software WinMACCS and ARCON.

Software Capabilities - RINO
RINO (Radiological Impacts of Normal Operations) models the public’s radiation exposure from radionuclides released by nuclear facilities during normal operation, following CSA N288.1. The software also evaluates the impact of conventional and radiological contaminants on non-human biota for nuclear facilities, following the CSA Standard N288.6. RINO can also compute the Derived Release Limits (DRLs) or Derived Emission Limits (DELs) for nuclear facilities, which need regulatory approval and are part of the operating license.
