14 nTOF4FAIR nTOF4FAIR Daniel Cano Ott, nTOF4FAIR – Proyecto Coordinado Plan Nacional I+D+i 2008, 18 de Mayo de 2010 (n,γ) cross section measurements of fissile materials The capture cross sections of fissile materials are prioritary data but are difficult to measure. Two competing channels which produce γ-rays:  (n,γ) and  (n,f) For fissile materials:  (n,f)  5 ·  (n,γ) → 10 times more γ-rays We have to distinguish the γ-rays from neutron capture from the γ-rays produced in the (n,f) reactions. Solution: measure the fission γ-ray background in coincidence with micromegas fission detectors. Successful test on 235 U performed in Real measurements have to follow.

Need of a high resolution and high efficiency neutron TOF spectrometer. Physics motivation

20 nTOF4FAIR nTOF4FAIR Daniel Cano Ott, nTOF4FAIR – Proyecto Coordinado Plan Nacional I+D+i 2008, 18 de Mayo de 2010 TOF spectrometer: array of liquid scintillators (BC501A) The MOdular Neutron SpectromTER - MONSTER CIEMAT has designed and is leading the construction of a 200 cell neutron spectrometer for the DESPEC (56 institutions, 350 researchers) experiment at FAIR. High intrinsic detection efficiency in the range of a few 100 keV up to tens of MeV. For neutron energies below 100 keV, a complementary system is needed. Funding is requested for the acquisition of a few doped ( 6 Li, 10 B) neutron detectors, efficient a energies below 100 keV.

21 nTOF4FAIR nTOF4FAIR Daniel Cano Ott, nTOF4FAIR – Proyecto Coordinado Plan Nacional I+D+i 2008, 18 de Mayo de 2010 Status of the project CIEMAT has completed the scintillator cell design: -Monte Carlo simulations (Diploma theses of E. Reillo and A. García). -Design of the light guide and optimisation of the light collection (Diploma thesis of A. García) -Characterisation of the prototype cell at the metrology laboratory PTB Braunschweig (E. Reillo and A. García) CIEMAT has completed the design of a low efficiency and low resolution 30 cell demonstrator (compatible with the future array). The demonstrator will be ready by the end of 2011 and used in experiments at the cyclotron of the University of Jyvaskyla in CIEMAT leads the international collaboration that will build MONSTER: Spain (CIEMAT, Instituto de Física Corpuscular), Finland (University of Jyvaskyla ), Sweden (University of Uppsala), India (VECC, University of Calcatta). CIEMAT has established a strong collaboration with the European research groups developing neutron detectors for SPIRAL-2: LPC – Caen (France) and Laboratori Nazionali di Legnaro (Italy) – NEDA project

22 nTOF4FAIR nTOF4FAIR Daniel Cano Ott, nTOF4FAIR – Proyecto Coordinado Plan Nacional I+D+i 2008, 18 de Mayo de 2010 CIEMAT is coordinating the neutron detector working group of the entire NUSTAR collaboration: 158 institutions and over 900 members.

25 nTOF4FAIR nTOF4FAIR Daniel Cano Ott, nTOF4FAIR – Proyecto Coordinado Plan Nacional I+D+i 2008, 18 de Mayo de 2010 The mechanical structure has been designed entirely by CIEMAT and made at CIEMAT’s workshops.

26 nTOF4FAIR nTOF4FAIR Daniel Cano Ott, nTOF4FAIR – Proyecto Coordinado Plan Nacional I+D+i 2008, 18 de Mayo de 2010 First part of the structure completed at CIEMAT’s workshops (May 2011)

27 nTOF4FAIR nTOF4FAIR Daniel Cano Ott, nTOF4FAIR – Proyecto Coordinado Plan Nacional I+D+i 2008, 18 de Mayo de 2010 The MONSTER demonstrator CIEMAT is currently building the 30 cell demonstrator of MONSTER. -Low energy resolution -Low efficiency Request: 10 more cells (+10 from IFIC) are necessary for reaching the target efficiency of 10% at 1 m flight path. Additional funding will be necessary for extending the structure to a larger number of modules.

28 nTOF4FAIR nTOF4FAIR Daniel Cano Ott, nTOF4FAIR – Proyecto Coordinado Plan Nacional I+D+i 2008, 18 de Mayo de 2010 We aim at manufacturing the Spanish in-kind contribution to MONSTER in Spain. Scientifica International has expressed strong interest and made a preliminary cost evaluation of an individual cell. The price is competitive with detectors available commercially (St. Gobain or SCIONIX).

29 nTOF4FAIR nTOF4FAIR Daniel Cano Ott, nTOF4FAIR – Proyecto Coordinado Plan Nacional I+D+i 2008, 18 de Mayo de 2010 The combined neutron and γ-ray spectrometry requires high simultaneous detection efficiencies: Largest efficiency of the neutron spectrometer (including solid angle) ~ 25% Largest efficiency of the γ-ray spectrometer based on Ge ~ 10% Neutron- γ coincidence detection efficiency ~ 2% For exotic isotopes, the Q β and P n values (neutron emission probabilities) become large. There are cases for which alternative γ-ray detectors like inorganic scintillators become a more reasonable choice. Improving the n-γ coincidence detection efficiency

31 nTOF4FAIR nTOF4FAIR Daniel Cano Ott, nTOF4FAIR – Proyecto Coordinado Plan Nacional I+D+i 2008, 18 de Mayo de 2010 “Recently” developed inorganic scintillators like LaBr 3 (Ce) do offer excellent energy resolution (better than NaI) and can be grown in large sizes (>3”x3”). They are a reasonable choice for combined neutron and γ- ray spectrometry when high efficiency is required. The request is part of CIEMAT’s R&D to the Total Absorption Spectrometer for DESPEC. Additional uses: -Photon strength function measurements at n_TOF. -Use as “neutron detectors” with neutron to γ-ray converters (R&D done by CIEMAT) thanks to its good energy resolution.

50 nTOF4FAIR nTOF4FAIR Daniel Cano Ott, nTOF4FAIR – Proyecto Coordinado Plan Nacional I+D+i 2008, 18 de Mayo de 2010 The 437 nuclear reactors in operation worldwide generate about 5800 tons/GW e /year of waste: Uranium and structural materials (94% of the mass). Can be considered as waste (like in Spain) or as valuable resources that should be reprocessed (like in France. Short lived fission fragments (5%). Decay in 300 years. Transuranic elements (1%): Pu, Np, Am, Cm… Highly radioactive and long lived. Difficult to handle over long periods ( to years). Uranium and structural materials Short lived fission fragments Transuranic elements Motivation: the problem of the nuclear waste

II.Partitioning and transmutation of the transuranic elements. Mid- and long-term (2030  ). The transmutation can take place in both ADS and Generation IV critical reactors (with fast neutron spectrum). III.Geological storage.
