Subject: XENON PREDICT CALCULATION CONCERN WITH FEBRUARY 29, 2000 DATE

Discussion:

On February 29, 2000, during a simulator training session, the licensee
determined that the xenon prediction program would not accept
February 29, 2000, as the starting date.  The xenon prediction program
located on a computer in the control room also would not accept
February 29, 2000.  The program functioned properly if any date other
than February 29, 2000, was used as a starting date.  The xenon
prediction software program is used to estimate new xenon, samarium, and
iodine levels for a given power level. The program is also used to
calculate current core burnup. Control room operators would use the
program following a reactor trip to predict the xenon concentration to be
used as an input to the estimated critical position calculation.

As immediate corrective action, the licensee used a starting date of
February 28, 2000, and the program successfully calculated the parameters
requested.  The power history information was not affected by this
problem.  If the xenon prediction program had not functioned, the
parameters could have been calculated manually.

The licensee determined that the application program was originally
compiled using Version 1 of Microsoft Visual Basic.  This version would
not accept the February 29, 2000, date.  As permanent corrective action,
the licensee plans to use Version 4 of Microsoft Visual Basic, which
corrects this problem.

Regional Action:

The resident inspectors were informed by the licensee and monitored their
corrective actions.
