PRIMARY SHIELDING CALCULATIONS ON THE IBM 650 (ROC CODES)

Description: Four programs written for the IBM 650 to calculate the gamma dose rates in the primary shielding of thermal reactors are described. Their functions are outlined as follows: Program 651-calculates the core attenuation coefficient and equivalent core gamma volumetric source values for a specific core. Program 652- calculates the activation gamma source data in the shield and prepares tabular data in machine storage for Programs 653 and 654. Program 653- calculates the gamma dose rates in the shie… more

Solutions of Systems of Differential Equations

Description: FOLDER is a routine whose purpose is to solve a system of linear differential equations on the IBM 650 computer which is equipped with index accumulators and floating-point hardware. A system of K n/sup th/-order differential equations which is represented by a system of K x n first-order differential equations and coded in a prescribed manner is solved numerically by the methods of Milne and/or Runge-Kutta. Flexible operating modes are made possible by the user's designtion of parameters. Outp… more

SO131--AN IBM-650 CODE TO SOLVE PRESSURE AND THERMAL STRESS PROBLEMS IN CORE SUBASSEMBLY PLATES

Description: In the design of nuclear reactor core subassemblies, a stress analysis is often made of a subassembly whose plates differ in geometry, in reactor coolant pressure loading, and in temperature distribution. Bettis code S0131 was developed for the IBM-650 computer to assess the adequacy of the subassembly design and to assist in determining acceptable manufacturing tolerances. The output of the code gives redundant weld reactions, deformations, and stresses in the individual plates. (auth)

NUCLEAR EXCURSION ANALYSIS ON THE IBM 650 (EARLY CODE)

Description: The Early Program is designed to compute the peak power and total energy release vhich will occur in a reactor due to a step increase of reactivity. These excursions may be terminated by one of several automatic shutoff mechanisms caused by the power excursion itself. The calculation assumes no thermodynanaic delays and assumes void formation is due to heat conduction from the cladding to the moderator. (W.D.M.)

ATBAC CHECK CALCULATION ON THE IBM 650, PROGRAM NO. 303

Description: This program, using the lBM 650 electronic data processing machine, is used primarily as a tool in order to prepare input data for an lBM 704 code ATBAC. The code calculates steady state thermal characteris tics of a plate type fuel element for both a nominal and adverse chanael. (auth)

NUCLEAR EXCURSION ANALYSIS ON THE IBM 650 (EARLY CODE)

Description: The early program is designed to compute the peak power and total energy release which will occur in a reactor due to a step increase of reactivity. The calculation assumes no thermodynamic delays and assumes void formation is due to heat conduction from the cladding to the moderator. For periods in the 1 to 10 msec. range, the calculation yields results which are in excellent agreement with SPERT experimental results. (W.D.M.)

Reflector and Pressure Vessel Cooling and Thermal Stress Analysis on the IBM 650

Description: S>These programs are intended to:ssist in establishing reflector cooling requirements, as well as thermal stresses in the reflectors and pressure vessel. The main program (304-Rec I) establishes required velocities between reflectors as a function of geometry, heat generation rates, material and fluid properties, and allowable surface temperature. This is done by iterating on velocities for successive water gaps. When required velocities have been established, corresponding thermal stresses are… more

THERMAL ANALYSIS ON THE IBM 650. LOVELY-I, PROGRAM NO. 55

Description: A program is given for the establishment of flow requirements of a tailored flow core. It is capable of handling either one- or two-pass cores, with flow direction optional in each pass, and a reflector coolant flow in parallel with elther pass. The various configurations which may be investigated are illustrated. Although the program is specifically intended for APPRtype elements, flows may be established for any set of dimensions snd pressure and temperature conditions and corresponding to an… more
