The fifth version of Japanese Evaluated Nuclear Data Library, JENDL-5, was developed. JENDL-5 aimed to meet a variety needs not only from nuclear reactors but also other applications such as accelerators. Most the JENDL special purpose files published so far were integrated into with revisions. consists 11 sublibraries: (1) Neutron, (2) Thermal scattering law, (3) Fission product yield, (4) Decay data, (5) Proton, (6) Deuteron, (7) Alpha-particle, (8) Photonuclear, (9) Photo-atomic, (10)...
Abstract Based on the results of IFMIF/EVEDA project in broader approach (BA) activities, conceptual design Advanced Fusion Neutron Source (A-FNS) to obtain irradiation data DEMO blanket materials is under consideration Japan. This paper describes progress A-FNS design, which consists a 40 MeV, 125 mA deuteron beam, liquid lithium target system, and test post-irradiation facilities. main objectives are acquisition RAFM up 2035 tritium recovery blanket. In addition, it expected be used for...
JENDL-5 was validated from a viewpoint of shielding applications under the Shielding Integral Test Working Group JENDL Committee. The following benchmark experiments were selected: JAEA/FNS in-situ experiments, Osaka Univ./OKTAVIAN TOF ORNL/JASPER sodium NIST iron experiment and QST/TIARA experiments. These analyzed with MCNP nuclear data libraries (JENDL-5, JENDL-4.0 or JENDL-4.0/HE, ENDF/B-VIII.0 JEFF-3.3). analysis results demonstrate that is comparable to better than JEFF-3.3 for neutron...
A plan of an advanced fusion neutron source (A-FNS) by using d-Li reaction is in progress at Rokkasho Japan. We investigate multipurpose usages the A-FNS addition to material irradiation test. Production medical isotope 99Mo considered as one usages. conducted a conceptual study on module for radioisotope production which was composed spectrum shifter and reflector. examined impacts materials reflector amounts production, their thicknesses. It concluded that beryllium most suitable both from...
Abstract The Linear IFMIF Prototype Accelerator, LIPAc, is being commissioned aiming at validating the RFQ up to 5 MeV beam acceleration. Eventually, nominal of MeV–125 mA in 1 ms length and Hz rate pulsed mode was achieved 2019. operation has been resumed since July 2023 after a long maintenance including recovery from unexpected problems RFQ-RF system. This new phase aims commissioning full configuration except SRF LINAC, which replaced by temporary transport line. Focusing on behavior, it...
A new benchmark experiment on lead with DT neutrons was designed and carried out a large assembly covered Li2O blocks at JAEA/FNS to validate nuclear data of for measurement reaction rates without impact background neutrons. The analyzed by using the MCNP5-1.40 code latest libraries, ENDF/B-VII.1, JEFF-3.2 JENDL-4.0. calculated underestimated measured ones depth. Moreover, tendencies C/Es were different among libraries. In order find reasons differences, we examined cross-sections in...
We have studied reasons of differences KERMA factors and DPA cross-section data among nuclear libraries. Here the included in official ACE files JENDL-4.0, ENDF/B-VII.1 JEFF-3.2 are examined more detail. As a result, it is newly found out that lot nuclei different followings: 1) large secondary particle production yield, 2) no gamma data, 3) files12–15 mt = 3, 4) 103–107 without 600 s–800 s file6. The issue considered to be due while issues 2)-4) seem NJOY. with these problems should revised...
The deuterium-tritium (D-T) experimental program on the Tokamak Fusion Test Reactor (TFTR) is underway and routine tritium operations have been established. technology upgrades made to TFTR facility demonstrated be sufficient for supporting both maintenance an extended D-T campaign. To date fusion power has increased ∼9 MW several physics results of importance reactor regime obtained: electron temperature, ion plasma stored energy all increase substantially in relative D-D at same neutral...
