Workshop N°1: Nuclear instrumentation and measurement in research reactors
- Christelle Reynard-Carette (Aix-Marseille University)
- Gordon Kohse (MIT Nuclear Reactor Laboratory)
Description
The development of nuclear instrumentation and measurement methods for major nuclear research facilities such as the Jules Horowitz Reactor under construction in France, the reactivated TREAT reactor in the USA and other research reactors in Europe for instance (MARIA, BR2, ...). Such facilities will offer extreme conditions requiring accurate, reliable and hardened sensors and detectors. The workshop will focus on recent advancements in nuclear instrumentation, and scientific and technological breakthroughs, through seven invited oral presentations. A variety of key measurement quantities (neutron and photon fluxes, nuclear heating rate, temperature, …) will be addressed and relevant possible topics will be detectors, sensors, irradiation devices, test benches, metrology, miniaturization, data acquisition, among others. The workshop will cover experimental and numerical studies carried out under laboratory conditions and during irradiation campaigns. The workshop will allow scientists and experts to discuss issues related to future challenges and identify potential joint work.
The MARIA research reactor is operated by the National Centre for Nuclear Research in Otwock, Poland. The MARIA reactor is a water and beryllium moderated reactor of a pool type with graphite reflector and pressurized channels. The fuel channels are situated in a matrix containing beryllium blocks. The MARIA reactor has been operating since 1974, and it has power up to 30 MW. Current main...
The Jules Horowitz irradiation reactor is under construction in the south of France. The objective of this new 100MWth research reactor is to carry out technological irradiations (Materials and Fuels) in support of current and future nuclear power plants (GEN2, 3 &4). https://jhrreactor.com/
It will also enable the production of artificial radioelements as well as the production of Moly...
LVR-15 is a 10 MW experimental reactor operated by Centrum výzkumu Řež (CVR), Czech Republic. The LVR-15 reactor is used primarily for irradiation of materials, production of radiopharmaceuticals, and experiments using neutron radiography and other applications of neutron beams. Although the reactor operates at atmospheric pressure and low coolant temperatures, materials can be irradiated...
Crucial nuclear facilities, such as Material Testing Reactors (MTRs), support existing nuclear power plants and future generations of reactors thanks to studies on material and fuels under representative and extreme conditions, including accelerated aging and accidental conditions. Due to the aging of the Material Testing Reactor (MTR) park, the Jules Horowitz Reactor (JHR), a new research...
The Jožef Stefan Institute TRIGA Mark II reactor has been used for many experiments to test nuclear instrumentation, to validate particle transport codes as well as to study various multiphysics phenomena. Among them are also experiments to study various temperature related effects. In the presentation we will present recent experiments in this field.
Firstly, the JSI TRIGA reactor will be...
SCK CEN has nearly 50 years of experience in conducting fuel performance assessments and qualifications, irradiating rod segments or plates in dedicated facilities installed at the high flux Belgian Reactor 2 (BR2). When those facilities are equipped with flow rate and temperature measurement, it is possible to deduce in real time the linear power produced in the tested fuel segments....
