ABSTRACT DETERMINAll0N OF PRO NEUTRON DECAY CONSTANT OF THE AP-600 REACTOR CORE. Detennination of prompt neutron decay constant of the AP-600 reactor core has been perfonned using combination of nvo codes WIMS 4 and Batan-2D IFF. The calaJIation was done at beginning of cycle and all of control rods pulled out. Cell ge eration from various kinds of core materials was done witIl 4 neutron energ}. group ill I-D trcmsporct ode S/D~). The cell is consideredf or ~ filel assemblyi n cluster model \\ith square pitch arrange aIld then, the dim ion of its unit cell is calaJIated. The unit cell consist of a fuel and moderator unit The unit cell dimensiona s. put data of \VIMSID;J code,c alled it aIU1ulusi,s obtained from tIle equivalent unit cell. Macroscopic cross secti ns as output was used as input of neutron diffusion code Batan-2Diff for core calculation as appropriate with ee enriclunent regions of the fuel of AP-600 core, n;unely 2; 2.5 and 3 %. From result of diffusion code (Ba -2DIFF) is obtained the value of delayed neutron fnlction of 6,932E-O3 and aveI"'clgper onlpt neutron life-time f 26.38 ~5,s o that the value of pronlpt neutron decay constaIlti s 262.8 s-l. If it is compared the calculation re It \VitIl the design value, the dC\'iation are, for the design value of delayed neutron fraction is 7.5E-{)3,a bout 0;;a, nd tIle designv alue of avcragep ronlpt neutron life time is 19.6 IS,a bout 34 IYor,e spectively. l1le deviatio beclusc tllere are still lmknO\\l1 SCVChcUo re conlponcnts of AP-600, so it diwl 't include in c<uClllationy et.
