RE: Y2K problems at a Nuke Plant?

["Richards, David" <david.richards@rfets.gov>]

Ron,
As an SRO you would certainly understand those systems better than me. But
my understanding of the NRC report (www.nrc.gov/NRC/NEWS/WIR/week3.html) is
that they lost both the primary and backup plant monitoring system (PMS)
computers in their entirety. The reference to safety parameter display
system (SPDS), emergency response data system (ERDS), and 3D Monicore
thermal limit monitoring system is that they were lost IN ADDITION TO the
PMS. This seems to have gotten lost in the press writeup. The NRC report
states that "operators determined that this constituted a major loss of
emergency assessment capability". Perhaps my understanding of what the PMS
does is somewhat off base. Wouldn't be the first time.
