We have performed an extensive search for correlated production of two or more photons at the 25MWTh reactor at Swierk/Poland/. We were looking for a prompt signal originating from decays of axions. Our experimental set-up consisted of an arry of nine 3'' x 3'' NaI/Tl/detectors, surrounded by active/plastic scintillators/ and passive shieldings, thus ncreasing experimental sensitivity as compared to other experiments in which two detectors were used. Data were collected during 26 weeks, with four days of reactor ''ON'', and three days of reactor ''OFF'' each week. Preliminary results are presented.
