3. 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.

4. 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.

5. 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.

6. TYPICAL RUNNING TIME:  Running  time  usually does  not  exceed  5
seconds.

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.
