Evaluation of nuclear data for JENDL Actinide File and High Energy Files is now in progress. JENDL Actinide File will contain evaluated nuclear data for 89 nuclides horn 2 0 8= to ‘5Fm including main fissile and fertile nuclides. The data are evaluated in the neutron energy region from 10‘5 eV to 20 MeV, by widely using theoretical calculations and systematic of parameters and cross sections. E...

Hexagonal boron nitride (hBN) possesses extraordinary potential for solid-state neutron detector applications. This stems from the fact that the boron-10 (B) isotope has a capture cross-section of 3840 barns for thermal neutrons that is orders of magnitude larger than other isotopes. Epitaxial layers of hBN have been synthesized by metal organic chemical vapor deposition (MOCVD). Experimental m...

Radiation sensitive polymer gels are among the most promising three-dimensional dose verification tools developed to date. Polymer gel dosimeter known by the acronym MAGIC has been tested for evaluation of its use in boron neutron capture (BNCT) dosimetry. We irradiated a large (diameter 10 cm, length 20 cm) cylindrical gel phantom in the epithermal neutron beam of the Finnish BNCT facility at ...

A LIXI(Light Intensifier X-ray Image) device has been employed in a real-time neutron radiography system. The LIXI is coupled to a video camera and the real-time images can be observed in a TV monitor, and processed in a computer. In order to get the real-time system operational, the neutron radiography facility installed at the IEA-R1m nuclear research reactor of the IPEN-CNEN/SP has been opti...

An electron spectrometer was used to measure the and ion spectra in two different irradiations of implosion laser deuterated spherical shell targets at direct fast ignition experiments on Gekko-LFEX facility. In transverse irradiation against LFEX axis, low effective hot temperature (Teff) huge neutron yield (Ny) could be obtained although high Teff Ny observed axial irradiation. irradiation, e...

Tungsten isotope compositions of magmatic iron meteorites yield ages of differentiation that are within 72 Ma of the formation of CAIs, with the exception of IVB irons that plot to systematically less radiogenic compositions yielding erroneously old ages. Secondary neutron capture due to galactic cosmic ray (GCR) irradiation is known to lower the eW of iron meteorites, adequate correction of wh...

The gradient of the neutron field in a nuclear reactor and requirements for permissible spread specific electrical resistance over volume silicon ingot makes it necessary to develop an irradiation device. This is especially true large ingots. One options reducing flux along height use neutron-absorbing screens design At WWR-K reactor, cadmium with natural isotopic composition used as screen mat...

Abstract International Fusion Materials Irradiation Facility-DEMO-Oriented NEutron Source (IFMIF-DONES) is a high-intensity neutron irradiation facility for qualification of fusion reactor materials, which being designed as part the European roadmap to fusion-generated electricity. Its main purpose study behavior materials properties under in flux able simulate same effects terms relevant nucle...

The applicability of the activation of an NaI scintillator for neutron monitoring at a clinical linac was investigated experimentally. Thermal neutron fluence rates are derived by measurement of the I-128 activity generated in an NaI scintillator irradiated by neutrons; β-rays from I-128 are detected efficiently by the NaI scintillator. In order to verify the validity of this method for neutron...
