RE: Y2K problems at a Nuke Plant?
I didn't intend to imply that the systems were not useful. I was trying to
indicate that even though some systems of this nature may not be available,
the systems redundancy and the Operator training that you referred to,
should prevent a loss of this nature from turning into a crisis. As noted
by your reference to Davis-Besse. One of the big problems noted as a result
of TMI were Operator training deficiencies. A great deal of effort has been
placed into operator training including the wide spread and rigorous use of
simulators ( a very interesting part of the training program, to say the
least )

I too am nowhere close to being an SRO but as an interested observer, I'd
respectfully note that there was a reason why the NRC required the SPDS in
the first place -- because a contributing factor to the TMI accident was
operator confusion due to key instrumentation being spread all over the
control room.
That said, I reported on the tornado strike at Davis-Besse last year and
know they lost their SPDS as well as the main plant computer for a time,
and no safety-significant problems resulted. That was due largely to proper
operator response, which the operators themselves attributed to intensive
training in the simulator under scenarios including tornado strike and
station blackout. I'm curious to what extent Y2K-type problems are being
incorporated into training scenarios, in the event some bugs don't get
worked out in time?

As a Senior Reactor Operator certified individual, I would like to note
that
while these systems are very useful in indicating the existence and
determination of the extent of a condition, all of the critical plant
parameter monitoring systems have other direct indications for the
operators. Radiation monitors, plant pressure and temperature and other
related parameters remain available to the Control Room Operators.

Perhaps, but it is critical to understand that these systems represent the
bulk of the Operator's ability to recognize and evaluate unsafe or
emergency
conditions in plant systems. Emergency Action Levels (EALs) and Emergency
Operation Procedures (EOPs) are based in very large part on the indications
provided by these systems. They are, in essence, the Operator's eyes and
ears.
