ABSTRACT

Purpose: To improve the safety culture of personnel of the department Andreev Bay of Northwest Center for Radioactive Waste SevRAO — branch of Enterprise for Radioactive Waste RosRAO (NWC SevRAO) for spent nuclear fuel and radioactive waste through the use of dynamic three-dimensional modeling software.

Material and methods: NWC SevRAO is temporary storage of radioactive waste generated during operation and decommissioning of the nuclear submarines and ships. According to an integrated expert evaluation this site is the most dangerous nuclear facility in the Northwest of Russia. Environmental rehabilitation of the site is now in progress and is supported by strong international collaboration. For the department Andreev Bay of NWC SevRAO was developed software tools that allows dynamically visualize the radiation situation and calculate doses in the virtual 3D model of the territory and buildings of the industrial complex.

Results: Designed software tools help to reduce uncertainty in the assessment of radiation exposure during operations, i.e. to have more precise information of the possible radiation doses. This result is achieved by visualization of the radiation field and by the ability of creation of different scenarios and simulation on the computer with real-time assessment of radiation effects on participants of these works. The input data for calculations can be measurements of the radiation situation, made by personnel of radiation safety service, or the information about the activity, radionuclide composition and geometry of radiation sources. Software includes a powerful analytical unit designed for radiation safety staff to support decision making process. Software tools allows to raise the qualification of staff through training, to optimize doses by modeling of different scenarios of work and to plan individual doses for personnel in the forthcoming operations.

Key words: radiation hazardous facilities, safety culture, 3D simulation, methodology ALARA, radiological protection
