If anyone wishes to see what that plant looks like since then,
there's a very clear satellite photo on google map showing the
damaged building unrepaired, if you select the 45 deg angle view
you'll get more details:

Not sure how old it is since 2009, but its clearly post accident.

The US Chemical Safety Board have released their report into the
2009 accident at NDK's synthetic crystal growing facility in
Belvidere IL <

It also describes the process.
Basically a 50ft autoclave failed, killing a member of the public at
a rest stop 650ft away. Looks like management decisions, probably
based on cost, overriding engineering advice even following an
earlier minor incident. The letters from a consulting engineer in
the annex make interesting reading. It illustrates the importance of
those professional engineers amongst us notifying and recording any
safety issues we discover. The facility is still shut down and the
insurance company won't settle as NDK were told of possible issues.
