Neutron transmission experiment with PTFE at AKR-2
Popis výsledku v původním jazyce
Fluorine is a crucial element for the nuclear industry and technology due to its application in nuclear fuel production as uranium hexafluoride (UF6), its use of Teflon (R) in criticality experiments, and its use in coolant/ fuel materials in several Molten Salt Reactor (MSR) concepts currently being designed. There have been many efforts to improve the neutron reaction cross sections for fluorine. The neutron broad-beam transmission experiment through the PTFE (PolyTetraFluoroEthylene) block at the Dresden AKR-2 reactor has been performed to validate existing evaluated cross-section libraries from 1 to 10 MeV of incident neutron energies. Calculations with studied data sets (ENDF/B-VIII.0, INDEN, JEFF-3.3, and JENDL-5) show satisfactory agreement with the experiment in the energy region above 2.1 MeV within the uncertainty range. The measured neutron transmission shows a systematic disagreement in a calculation to experiment comparison in the energy region 1-2.1 MeV. This behavior is consistent with the measured 252Cf(s.f.) neutron leakage in the PTFE block with dimensions of 60 x 50 x 50 cm. Improvement of evaluated cross sections below 2 MeV of neutron incident energy is needed.
