The detector will consists in an array of close-packed single modules, each of them coupled to two high efficiency Hamamatsu photomultipliers. Two 12.5 kg each NaI(Tl) crystals provided by Alpha Spectra are currently taking data at the LSC. These modules have shown an outstanding light collection efficiency (12-16 phe/keV), about the double of that from DAMA/LIBRA phase 1 detectors, which could enable reducing the energy threshold down to 1 keVee. ANAIS crystal radiopurity goals are fulfilled for 232Th and 238U chains, assuming equilibrium, and in the case of 40K, present crystals activity (although not at the required 20 ppb level) could be acceptable. However, a 210Pb contamination out-of-equilibrium has been identified and its origin traced back, so we expect it will be avoided in next prototypes. Finally, current status and prospects of the experiment considering several exposure and background scenarios are presented. 000056138 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio2010-MULTI-DARK-CSD2009-00064$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2011-23749 000056138 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000056138 592__ $$a0.313$$b2016 000056138 593__ $$aNuclear and High Energy Physics$$c2016$$dQ3 000056138 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000056138 700__ $$0(orcid)0000-0002-6948-5101$$aCebrián, S.$$uUniversidad de Zaragoza 000056138 700__ $$0(orcid)0000-0003-1190-7233$$aCuesta, C. 000056138 700__ $$0(orcid)0000-0002-9827-2332$$aGarcía, E.$$uUniversidad de Zaragoza 000056138 700__ $$0(orcid)0000-0002-4643-2138$$aGinestra, C. 000056138 700__ $$0(orcid)0000-0002-9043-4691$$aMartínez, M. 000056138 700__ $$0(orcid)0000-0001-7025-061X$$aOliván, M.A.$$uUniversidad de Zaragoza 000056138 700__ $$0(orcid)0000-0002-2793-7544$$aOrtigoza, Y. 000056138 700__ $$0(orcid)0000-0001-8278-6032$$aOrtiz de Solórzano, A.$$uUniversidad de Zaragoza 000056138 700__ $$0(orcid)0000-0002-5457-3694$$aPobes, C. 000056138 700__ $$0(orcid)0000-0001-8732-8196$$aPuimedón, J.$$uUniversidad de Zaragoza 000056138 700__ $$0(orcid)0000-0002-7552-1228$$aSarsa, M.L.$$uUniversidad de Zaragoza 000056138 700__ $$0(orcid)0000-0003-0228-7589$$aVillar, J.A.$$uUniversidad de Zaragoza 000056138 700__ $$0(orcid)0000-0002-6519-4315$$aVillar, P.$$uUniversidad de Zaragoza 000056138 7102_ $$15007$$2520$$aUniversidad de Zaragoza$$bDpto.
