Innovative in-pile instrumentation is crucial for advanced experimental programs in research reactors. In this field, we developed a specific acoustic sensor to improve the knowledge of fission gas release Pressurized Water Reactor (PWR) fuel rods when irradiated Material Testing Reactors (MTR). order perform related study kinetics, CEA (French Nuclear Energy Commission) acquired ability equip pre-irradiated PWR rod with three sensors, allowing simultaneous on-line measurements following...
Four grades of commercial PZT materials have been exposed to nuclear radiation during five months in an irradiation channel the BR1 research reactor at SCK̇CEN (Belgium). This experimental study was performed framework Joint Instrumentation Laboratory with CEA French Commission Atomic Energy validate these for future applications severe conditions such as online measurements experiments reactors. For this purpose, thin piezoelectric discs were irradiated while a remote network analyser...
The production of high-purity radioactive ion beams (RIB) through the isotope separation online (ISOL) method makes possible unique research programmes in several fields science. demand for beam time continues to be high, while study more and exotic isotopes, difficult produce sufficient quantities, is primary interest many currently defined projects. At same time, growing from medical field cannot pass unnoticed, where ISOL technique gives access most innovative with extremely-high specific...
We describe the state of art research towards ultrasonic measurement methods for use in lead-bismuth cooled liquid metal reactors. Our current activities are highly focused on specific tasks MYRRHA system, which is a fast spectrum reactor with eutectic mixture lead and bismuth (LBE) conceived as an accelerator driven system capable operating both sub-critical critical mode. As opaque to light, normal visual feedback during fuel manipulations vessel not available must therefore be replaced by...

Abstract At ISAC-TRIUMF, a 500 MeV proton beam is impinged upon “thick” targets to induce nuclear reactions produce reaction products that are delivered as Radioactive Ion Beam (RIB) experiments. Uranium carbide among the most commonly used target materials which produces vast radionuclide inventory coming from both spallation and fission-events. This can also represent major limitation for successful delivery of certain RIBs experiments since, given mass, many isobaric isotopes be filtered...
The Belgian Nuclear Research Center SCK·CEN is in the process of developing MYRRHA, a generation IV fast flux research reactor to replace aging BR2. MYRRHA conceptualized as an accelerator driven system cooled with lead bismuth eutectic mixture (LBE). As LBE opaque light, visual feedback during fuel manipulations not available and must therefore be replaced by that hindered opacity coolant. In this respect, ultrasonic measurement techniques have been proposed even developed past for...
The Belgian Nuclear Research Centre SCK-CEN is in the process of developing MYRRHA a fast flux research reactor, cooled by lead bismuth eutectic mixture (LBE). As LBE opaque to visual light, ultrasonic techniques will be employed provide feedback submerged operations. One tasks tackled using ultrasound locating potentially lost fuel assembly. Unfortunately, standard machined stainless steel objects, such as assembly, reflect an pulse specular way which induces stringent requirements on...
In some nuclear reactors the core is intended to be cooled by means of liquid metal, for example, lead-bismuth eutectic alloy. For safety and licensing reasons, an imaging method interior reactor has thus developed. The paper devoted development ultrasonic imagi ng measurement technique suitable performance in Pb/Bi
The Belgian Nuclear Research Centre (SCK·CEN) is in the process of designing MYRRHA, a new multi-purpose irradiation facility to replace ageing BR2. MYRRHA fast spectrum reactor cooled with lead-bismuth eutectic (LBE). As liquid metal opaque visual light, ultrasonic measurement techniques are selected fulfill essential tasks that, according our assessment, will be demanded by licensing authorities, particular: fuel assembly identification and localization lost assembly. To that end,...
Optimizing process outcomes by tuning parameters through an automated system is common in industry. Ideally, this optimization performed as efficiently possible, using the minimum number of steps to achieve optimal configuration. However, care must often be taken ensure that, pursuing solution, does not enter “unsafe” state (for itself or its surroundings). Safe Bayesian a viable method such contexts, it guarantees constraint fulfillment during process, ensuring remains safe. This assumes...
This paper presents a system for visualizing the interior structure of vessel filled with liquid metal. Due to opaque and conductive nature medium, regular visualization systems based on cameras, electromagnetic or laser techniques can't be used. The operation, strengths weaknesses an existing set-up are investigated by creating scenario find extract rectangular object inside in shortest possible time. main focus this is not designing new but investigate bottlenecks that faced need kept mind...
