چکیده

This paper overviews certain radiation detection, perception, and planning challenges for nuclearized robotics that aim to support the waste management and decommissioning mission. To enable the autonomous monitoring, inspection and multi–modal characterization of nuclear sites, we discuss important problems relevant to the tasks of navigation in degraded visual environments, localizability–aware exploration and mapping without any prior knowledge of the environment, as well as robotic radiation detection. Future contributions will focus on each of the relevant problems, will aim to deliver a comprehensive multi–modal mapping result, and will emphasize on extensive field evaluation and system verification.

Prioritization methodology for the decommissioning of nuclear facilities: a study case on the Iraq former nuclear complex.

There are a number of sites in Iraq which have been used for nuclear activities and which contain potentially significant amounts of radioactive waste. The principal nuclear site being Al-Tuwaitha. Many of these sites suffered substantial physical damage during the Gulf Wars and have been subjected to subsequent looting. All require decommissioning in order to ensure both radiological and non-r...

Towards a Safety Case for the Use of Laser Cutting in Nuclear Decommissioning (a0193)

Some of the requirements in nuclear decommissioning include size reduction of contaminated containers, pipework and other structures manufactured from stainless and other steels. Size reduction is generally performed using mechanical saws or shears, with drawbacks of quick wear, significant applied force, difficult remote operation and addition to contaminated waste mass. The use of lasers for ...

Mobile laboratories: An innovative and efficient solution for radiological characterization of sites under or after decommissioning.

During the operation and the decommissioning of a nuclear site the operator must assure the protection of the workers and the environment. It must furthermore identify and classify the various wastes, while optimizing the associated costs. At all stages of the decommissioning radiological measurements are performed to determine the initial situation, to monitor the demolition and clean-up, and ...

Plasma source mass spectrometry for radioactive waste characterisation in support of nuclear decommissioning: a review

The efficient characterization of nuclear waste materials represents a significant challenge during nuclear site decommissioning, with a range of radionuclides requiring measurement in varied and often complex sample matrices. Of the available measurement techniques, inductively coupled plasma mass spectrometry (ICP-MS) has traditionally been applied to long-lived radionuclides, particularly in...

Nuclear Decommissioning and Organisational Reliability: Involving Subcontractors in Collective Action

The concept of organisational reliability is at the heart of the safety of at-risk systems. Many studies have been conducted in the nuclear industry; all emphasise the study of plants in normal, daily operation or during shutdowns. However, decommissioning, whether ongoing or planned, places a sharp focus on the question. This is because, on the one hand operating companies make significant cha...
