[en] Prior to the CAORSO 3.26 fuel data bank had been generated whose active longitude was of 144 inches, longitude that not this in agreement with the used assemblies in the unit 1 of Laguna Verde, of 150 inches of active longitude. When realizing this difference, it was speak with the personnel of the CAORSO plant to verify if there was some error in the sent information. The CAORSO personnel, when verifying it, point out that they sent us information of another fuel and that the appropriate one for our plant is that of the CAORSO 3.29 fuel, that which made necessary the generation of this bank. In this work in a general way the form in that was generated the data bank of the CAORSO 3.29 fuel to analyze their use in a future reload for Laguna Verde is described. The formation of the bank was carried out with the ECLIPSE 86-2D, RECORD 89-1A and POLGEN 88-1B of the FMS package installed in the VAX system of the offices of the National Commission of Nuclear Safety and Safeguards in Mexico D.F and in the Electric Investigations Institute in Cuernavaca, Morelos. The formed bank is denominated 'L1PG9110' and was carried out following the '6F3/I/CN029/90/P1' procedure. The generated data bank contains the enough information in terms of constant in two groups of burnt dependent and instantaneous vacuums, for the different arrangements of fuel bars present in the assemble, as well as those coefficients that take into account the presence of the control bar, the variation in the fuel temperature and the effect of the 'historical' vacuums. All this is included in that is known as SUPER option of the bank for PRESTO with the options PRCOEF and POLRAM. Also, in the Annex G of this report, is provided by separate the M-FACTOR, the Xenon coefficients and the burnt parameters of the control bar for PRESTO. Its are also presented charts and comparative graphic of the obtained results in the BURNT series of the cell for three vacuum percentages in the moderator, 0%, 40% and 70% for each one of the five cells identified in the one assemble.
