3. DESCRIPTION OF PROGRAM 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.

4. METHODS

PWR-PPM utilizes the explicit solution of the single system dilution and boration equations and linear interpolation of the compressed liquid tables.

7. 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.
