● The nuclear Industry is The nuclear Industry is going through a going through a renaissancerenaissance
● New Stations are under New Stations are under constructionconstruction
● While the older stations While the older stations approach the end of their approach the end of their useful livesuseful lives
● Decommissioning Decommissioning provides exciting provides exciting opportunities for research opportunities for research and developmentand development
What does my research involve?What does my research involve?
● The research involves the creation of a system that takes 3D scans from scanner in a radiation environment for the purpose of planning decommissioning projects.
ObjectivesObjectives
● The scans produce point clouds which are 3D representations of an objects.
● Each point in the cloud is an XYZ coordinate.
● The objective is to take the point clouds and reconstruct them in the computer aided design package Solidworks, with information on radioactive sources.
● So what does a point cloud look like???
Here's an exampleHere's an example
What needs to be scanned?What needs to be scanned?
● One of the environments that needs to be scanned is called a Cave, what is a Cave?
● A Cave is a place where High Level Waste (HLW) is handled for the purpose of disposal, also such Caves can be used for experimentation.
● Naturally the HLW will emit significant levels of Gamma Radiation that prevents Human access for the purpose of survey.
● Inside the Cave is a complex environment of pipes and various components.
● Here's a couple of good cases...
The CaveThe Cave
Getting the scanner to the objectsGetting the scanner to the objects
● In the case of the cave the scanner will be taken to objects and structures with a remotely operated arm.
● The scanner will orientated by this arm into various positions.
● The scans from these positions will be combined together to form a complete 3D picture.
The Research challenge The Research challenge (The exciting and fun part!)(The exciting and fun part!)
● The development of software that will extract the objects three dimensional definition from its point cloud.
● Elimination of unwanted points to save processing time while retaining critical points that define the objects shape.
● Use of artificial intelligence in design to create an efficient piece of software
Also...Also...
● There will be areas that the remote manipulator arm will not be able to reach with the scanner...
● Radiation fluences may exist that could damage the delicate electronics of the scanner...
● Some pipes and components in the room will stand in the way of other objects thus hiding these objects from scans...
● These are some of the many and exciting challenges that lie ahead...
