To decommission the Fukushima nuclear power plant after accident caused by a tsunami in 2011, characterization of fuel debris is required.The precise location and radiological composition are currently unknown, area submerged making it difficult to investigate primary containment vessel.An integrated system that includes both radiation detectors sonar will allow full localization debris.This paper describes research completed toward development complete system, on-board low-cost, small...
Surveying active nuclear facilities for spread of alpha and beta contamination is currently performed by human operators. However, a skills gap qualified workers emerging set to worsen in the near future due under recruitment, retirement increased demand. This paper presents an autonomous ground vehicle that can survey alpha, gamma radiation generate heatmaps. New methods preventing robot from spreading radioactive using state-machine costmaps are introduced. first detect autonomously...
Abstract This paper presents the Vega robot, which is a small, low cost, potentially disposable ground robot designed for nuclear decommissioning. has been developed specifically to support characterization and inspection operations, such as 2D 3D mapping, radiation scans sample retrieval. The design construction methodology that was followed develop described its capabilities detailed. provide flexibility, both in software hardware, controlled via tele‐operation, although it can be extended...
Robotics and embedded systems are increasingly used deployed in harsh environments such as nuclear decommissioning radioactive waste handling. Development of new, low-cost, robotic solutions, requires commercial-off-the-shelf (COTS) components to survive exposure. Understanding the response these γ-radiation is important for safe reliable deployment. Power supply regulation microcontrollers have been highlighted sensitive radiation this study determines experimentally characteristics...
The use of robotics in harsh environments, such as nuclear decommissioning, has increased recent years. Environments the Fukushima Daiichi accident site from 2011 and Sellafield legacy ponds highlight need for robotic systems capable deployment hazardous environments unsafe human workers. To characterise these it is important to develop robust accurate localization that can be combined with mapping techniques create 3D reconstructions unknown environment. This paper describes development...
This paper describes the development of a submersible system based on remote-operated vehicle coupled with radiation detectors to map interior reactors at Fukushima Daiichi nuclear power station. It has aim oflocating fuel debris. The AVEXIS used in this study been designed as low-cost, potentially disposable, inspection platform that is smallest its class and capable being deployed through 150 mm diameter access pipe. To gamma-ray environment, cerium bromide scintillator detector small form...
Instruments and Methods were developed to explore fuel debris at the bottom of Primary Containment Vessel in Fukushima Daiichi Nuclear Power Plant.A Remotely Operated Vehicle was designed investigate distribution surface profile primary containment vessel using a sonar compact radiation detector.Several tests carried out various facilities determine capabilities gamma-ray detector feasibility device.
The premise behind this research is the characterisation and integration of a unique detector system on board submersible, remotely-operated vehicle (ROV) for end purpose fuel debris at Fukushima Daiichi. Currently, Whilst precise knowledge location core not known it commonly assumed that has leaked through into base pedestal below suggested may have moved outside lower plenum. flooding reactor floors immediately following accident adds an extra element complexity detection requiring to be...
