for 89 fission products (representing 99% of fission product absorption). The ANSWERS Monte Carlo code MONK can be run using discrete energy dependence, by utilising a broad group (i.e. 172 groups) nuclear data library, or using continuous (or point) energy. This latter option removes the approximations inherent in using discrete energy groups. To run in point energy mode, MONK uses the BINGO [1] collision processor and associated point energy nuclear data library. BINGO is the successor to the DICE collision processor which utilised a hyper-fine energy group scheme (13193 groups). For the point energy BINGO library, it is necessary transform the evaluated data from the standard ENDF-6 format, to a form that allows efficient Monte-Carlo sampling. This is done using a code called the BINGO Pre-Processor (BPP). The BPP uses the NJOY nuclear data processing code to reconstruct and Doppler broaden the crosssections to form a smoothly varying function of energy. The secondary angle and energy data for emitted neutrons are transformed into equi-probable bins or probability functions. The broad group library used by MONK is identical with the library applied in the ANSWERS deterministic neutronics code, WIMS. For this library, NJOY is again used to reconstruct and Doppler broaden the cross-sections but, in this case, NJOY is further used to produce the group averaged data for both the cross-sections and emitted data. These data are then transformed into the specific form required for the WIMS library. This paper will describe the methodologies used to generate the BINGO point energy and WIMS broad group libraries. It will also present MONK benchmark results for libraries derived from the JEFF3.1.2 evaluated data library.

Sublet, UKAEA, United Kingdom. The “Neutrons For Science” (NFS) facility will be a component of SPIRAL-2 laboratory under construction at Caen (France). The SPIRAL-2 facility will be dedicated to the production of high intensity of Radioactive Ions Beams (RIB). The high-power, superconducting driver LINAG (linear accelerator of GANIL) will accelerate deuteron beams to produce neutrons by breakup reactions on a C converter.These neutrons will 184
induce 238 U fission producing radioactive nuclei. Additionally to the RIB production the Linag Experimental Area (LEA) will allow to use stable beams (protons, deuterons as well as heavy ions) delivered by the accelerator: NFS is one of the two facilities of the LEA. NFS will be composed of a pulsed neutron beam for in-flight measurements and irradiation stations for cross-section measurements and material studies. The beams delivered by the LINAG will allow producing intense pulsed neutrons sources in the 100 keV-40 MeV energy range. Continuous and quasi-monokinetic energy spectra will be available at NFS respectively produced by the interaction of deuteron beam on thick Be converter and by 7 Li(p,n) reaction on thin converter. The flux at NFS will be up to 2 orders of magnitude higher than those of other existing time-of-flight facilities in the 1 MeV - 40 MeV range. Irradiation stations for neutron, proton and deuteron induced reactions up to 40 MeV will also allow to perform cross-sections measurements by activation technique. NFS will be a very powerful tool for physics, fundamental research as well as applications like the transmutation of nuclear waste, design of future fission and fusion reactors, nuclear medicine or test and development of new detectors. The facility and its characteristics will be described, and several examples of the first potential experiments will be presented.

Wagner Helmholtz-Zentrum Dresden-Rossendorf, Postfach 510119, 01314 Dresden, Germany The compact neutron-time-of-flight facility nELBE at the superconducting electron accelerator ELBE of Helmholtz-Zentrum Dresden-Rossendorf is currently being rebuilt. From the beginning of 2013 a new enlarged experimental hall with a flight path of up to 10 m will be available. As the neutron radiator consists only of a liquid lead circuit no moderated neutron are produced and also the background from capture gamma rays is very small [1]. The useful neutron spectrum extends from some tens of keV to about 10 MeV. As the electron bunch length is only a few ps the energy resolution in the MeV range is dominated by the timing resolution of the detectors. nELBE is intended to deliver cross section data of fast neutron nuclear interactions e.g. for the transmutation of nuclear waste and improvement of neutron physical simulations of innovative nuclear systems. The inelastic scattering of 56 Fe was investigated both with a double-time-of-flight experiment i.e. the scattered neutron and the de-excitation photon are measured in coincidence using a BaF2 scintillator and plastic scintillator arrays. In the same experiment, the gamma production cross section was measured with an HPGe detector and the inelastic neutron scattering cross section to the first few excited states in 56 Fe was determined. An experiment to measure the neutron induced fission cross section of 242 Pu using fast ionisations chambers with homogeneous actinide deposits is in preparation [2]. The neutron total cross sections of Au and Ta were determined in the energy from 200 keV to 7 MeV using a plastic scintillator in a transmission experiment.
