Title: ART-04--A MODIFICATION OF THE ART PROGRAM FOR THE TREATMENT OF REACTOR THERMAL TRANSIENTS ON THE IBM-704

Abstract

Several recent modifications of the ART program for the study of the behavior of a nuclear reactor during various thermal transients are described. The program requires a 32,000-word IBM-704 computer with six tape units. The major modifications are provision for a slip flow model and for void reactivity contribution. (auth)

  • A description is given of a program by which the behavior of a nuclear reactor during various thermal transients may be studied. The program is written for a 32,000-word IBM-704 computer with six tape units. It is designed to predict the behavior of a water-cooled and moderated reactor with flat plate fuel elements during transients which are slower than a prompt excursion and during which the reactor flow. inlet temperature, and control rod motion may be specified as a function of time.

  • SPY (D1G) is an IBM-704 digital-computer program developed specifically for the calculation of thermal transients occurring in a three primary coolant loop, one-pass nuclear reactor system. The program has the computing ability to provide the supponting calculations for the analysis of complete and sequential loss-of-flow accidents, coldwater accidents, stant-up accidents, and other accidents which may be simulated by externally controlled variations in reactivity. Inclusion of a three-channel core model and the effects of interchannel flow redistribution provide a basis for the complete transient thermal aralysis of both nominal and hot channels. Two versions of the program are available: SPY 1more » employing three radial nodes and SPY 2 employing six radial nodes to describe the thermal transient effects in terms of fuel-element meat, cladding, and surface temperatures, and bulk-coolant temperatures. Each version contains an option for eliminating all thermal and hydraulic calculations in one of the three channels. Operation of the program requires an IBM-704 digital computer of 16,000-word minimum core storage. (auth)« less
  • In order to use many of the thermal design codes, it is necessary to nodalize the continuous power distributions. A code, PST, intended for this purpose is described. PST is primarily useful where either volume normalized or power fraction data is required. Both are obtained from PST. PST is an outgrowth of a previous code, PAS. The changes from PAS allow determination of the nodalized power fraction and the unity normalized water rise integral. (auth)
  • The TRANSITO program solves the heat transfer equations for the steady state and transient temperature distribution in a three-dimensional geometry (space and time), using a first-forward finite difference method to solve the system of differential equations. The dependence of the physical parameters on temperature is accounted for in the Fourier equations. Given the assembly's geometrical and physical description, the code yields the temperature distribution as a function of time. The mathematical approach and the nature of input-output data are given, and a sample calculation is presented along with the Fortran statements of the code. (auth)
