Title: TURBO--A TWO-DIMENSIONAL FEW-GROUP DEPLETION CODE FOR THE IBM-704

Abstract

TURBO is a two- or four-group depletion code in twodimensions and is the direct counterpart of the onedimensional code, CANDLE. The neutron flux values are computed in elther x-y or r-z geometry by using a modification of PDQ. The parameters used in the diffusion equations are derived from effective one- velocity microscopic cross sections for the elements comprising the media. These elements are described by their isotopic densities and thermal self-shielding factors. The flux values obtained are normalized to a specified power output. Assuming flux and power to be constant for a specified period of time, called a time-step, the isotopic densities are recomputed according to the equations given previously. Two magnetic tapes of interest are generated during the calculation. The first, called the history tape, contains ail of the information needed to continue to the next time-step. i.e., isotopic densities of time-dependent elements and converged flux values. The information needed in a thermal survey code is also saved. The second tape. called tae binary output tape, contains information already calculated which may be selectively processed for printing by the output routine. The TURBO code consists of seven separate routines: the first is the x-y calculation (TURBO 1), the secondmore » is the r-z calculation (TURBO 2), the third is the maximum xenon calculation in x-y geometry (TURBO 3), the fourth is the maximum xenon calculation in r-z geometry (TURBO 4), and the fifth is the output routine (TURBO 5). The last two routines are essentially service routines. One of these, TRSE, is to be used when the Endof Tape condition is encountered on the history tape to allow the computation to continue beyond this point. The other routine, (TURBO 0) allows replacement of rectangular blocks of burnable materials or the movement of one block to another location. (auth)« less
