Embodiment Construction

[0066] The present invention therefore relates to a method of intervention in a radioactive area 1 by at least one operator.

[0067] This area is called a radioactive area in the sense that it is located in a facility containing radioactive materials. It itself contains or may contain radioactive material.

[0068] The facility is a basic nuclear facility (BNI), such as a nuclear reactor, nuclear fuel cycle facility or laboratory. Alternatively, the facility is an ICPE (Environmentally Classified Facilities) or any other facility.

[0069] The region is of any type. This area is eg a reactor pool, a hot cell or any place classified as a contaminated area of ​​the INB open access for maintenance operations.

[0070] Interventions are intended to carry out various works in radioactive areas: maintenance work, cleaning, dismantling, etc.

[0071] The intervention is carried out by a single operator in the radioactive area 1 or conversely by a team of several operators simult...

Abstract

The invention relates to a method and assembly for intervention in a radioactive zone. Said method comprises the following steps: production of a digital model representing the three-dimensional topography of the radioactive zone (1); and intervention of the at least one operator in the radioactive zone (1), the intervention step comprising at least the following substeps: repeated measurement ofthe radioactive radiation intensity by a portable detector (3), and determination of the spatial coordinates of the portable detector (3) at the time of the measurement; recording of a plurality of said measurements and the corresponding spatial coordinates in the digital model; and materialisation of the recorded measurements in an augmented reality device (5) worn by the at least one operator, by a plurality of discrete holographic symbols (7).

Description

technical field [0001] The present invention relates to intervention operations in radioactive areas. Background technique [0002] In the case of maintenance operations in nuclear facilities, operators working in controlled areas face several risks: [0003] - Radiological risks (environmental dose rates, hot spots, radioactive contamination). [0004] - General safety (risks of falling, load handling, working at heights, hypoxia, burns, etc. at the same level). [0005] Consideration of these various risks enables maintenance operations to be carried out in complete safety while limiting the integrated dose to a strict minimum level (ALARA principle). [0006] Many of these risks are undetectable to human senses (pollution, ionizing radiation) or can be masked by the work environment (risk of falling into floor openings, risk of no-travel areas during load handling operations, or more generally say any risky situation that cannot be permanently flagged). Additionally, ...
