Description

A decision-support tool combined with 3D simulation

Visiter le site de OREKA Solutions

DEMplus for nuclear is the first 3D simulation software for interventions in nuclear field.

DEMplus for nuclear, by OREKA Solutions, uses technological components developed by CEA. It is a real decision-support tool which responds to current work challenges.

Whatever the project (new works, operation, maintenance or decommissioning works) is, DEMplus ensures a better safety and waste management, major cost and planning cuts, whilst using the ALARA approach.

Created by nuclear experts for nuclear experts, DEMplus is a business software easy to use. It allows collaborators, involved in the same project, to work together from the beginning to the end (reports and schedules).

Sensitivities studies can easily be performed allowing an optimum scenario choice, according to the project criterias.
This enables safty improvement and gains increase (up to 30%).

At the end, DEMplus for nuclear is the answer to the nuclear industry challenges, thanks to 3D simulation.

Modules

DEMplus® for nuclear main functionalities on video

  • Dosimetry

    The dosimetry module provides a dosimetric mapping based upon the radiological sources and screens. It computes in real time the equivalent dose rate received by the operator (or robot) based on his location.

  • Cutting module

    With the cutting module, partial cutting can also be performed on objects, either to remove material or to improve the 3D model by dissociating items within the same model.

  • Anti-collision

    Users drive their avatar or robotic arm in the 3D model using a space mouse®. The anti-collision module, detects instantaneously any contact between the avatar (operator or robot) and his surroundings. This allows a better check on the accessibility.

  • Kinematic

    This module enables any kinematic process to be conducted (handling systems, robot, bridge crane, ). Users confirm the tool performance by checking the process capacity and its accessibility.

C3D approach

Cost, dose, waste, time

Whatever the project, the complexity and specificity of nuclear projects, in particular the radioactivity that characterizes them, make the development of a scenario difficult.

Parameters, such as cost, dose, waste, and time, are tightly linked.
This is the reason why, to define the best scenario, our computation models incorporate this interdependency: this is the C3D approach.
