I suspect that the nuclear power industry is one place that you'll
find the oldest stuff, however, given the long regulatory approval
process for change.
I remember a nuclear reactor (research, not power generation)
controlled by a PDP-9.
For Ontario Power Generation (formerly Ontario Hydro), the Nuclear
Power Generation
station at Darlington (just East of Toronto) still uses the PDP-11
running RSX-11. A
refurbishment is either in progress of will commence soon and that
might change, but
it is unlikely. It is easier to continue to use the original hardware
and software than
to completely revamp the system. In the past, only the servicing
hardware tends to
change.

The Pickering Nuclear station ran on IBM 1800s and Bruce ran on PDP-8s.
The Nanticoke Coal fired thermal plant also used 1800s. I recall in my
early days at IBM they reconned a 1800 on our education center lab floor
for Ontario Hydro. They self serviced all their systems and a friend
who did a work term at Bruce was telling me they had a room full of
PDP-8s for spare parts.
