Measurement and Analysis of Neutron Leakage Spectra from Pb and LBE Cylinders with D-T Neutrons

EPJ Web of Conferences, 2017
For validating the current evaluated neutron data libraries, neutron leakage spectra from lead and lead bismuth eutectic (LBE) cylinders have been measured using an intense D-T pulsed neutron source with time-of-flight (TOF) method by Institute of ...

Novel integrated structure and function of Mg–Gd neutron shielding materials

Nanotechnology Reviews
As the lightest metal structural materials, magnesium (Mg) alloys offer extensive application potential. Gadolinium (Gd), as the primary alloying element in Mg alloys and recognized for its notable thermal neutron capture cross-section, is considered one

Supermc neutron simulation - burnup of different composition and distribution of burnable poisons in VVER-1000 reactor

, 2021
Различный состав и пространственное распределение выгорающих поглотителей по-разному влияют на размножающие и теплофизические свойства реактора. В работе создана расчетная 3D модель ТВС реактора с выгорающими поглотителями. В качестве выгорающих поглотителей используются традиционно-применяемые Gd2O3-содержащие твэлы и твэлы с AmO2. Проведенные расчеты
