PWR-PPM, Boration-Dilution Tables Generator for PWR Operation

1 - Description of problem or function: PWR-PPM generates boration- dilution tables used by the reactor operator of a PWR. The computer printed tables plot initial and final reactor coolant system boron concentration in units of ppm boron against the gallons of makeup water and boric acid solution required to obtain the desired ppm change. These tables replace nomographs normally required for boration and dilution operations. 2 - Method of solution: PWR-PPM utilizes the explicit solution of the single system dilution and boration equations and linear interpolation of the compressed liquid tables. 3 - Restrictions on the complexity of the problem: The temperature between and including 100 degrees F. to 600 degrees F. and the pressure between and including 200 psig to 6000 psig. 4 - Unusual features of the program: Only five input parameters are required: (1) weight per cent of boric solution in make-up steam, (2) volume of the reactor coolant system, (3) temperature of the reactor coolant system, (4) pressure of the reactor coolant system, and (5) title card
