Called
to
ask
about
construction
of
the
passive
screen
retrofit
at
the
WH
Zimmer
Plant
in
Ohio.

Plant
started
operation
in
1989.
Confirmed
that
plant
was
originally
constructed
as
a
nuclear
plant
but
converted
to
coal
before
completion.
Noted
that
the
cooling
system
was
recirculating
cooling
towers
and
that
if
there
was
a
problem
with
the
screens
they
are
set
up
to
use
treated
wastewater
as
an
alternative
source
if
needed.
He
said
that
sometimes
the
screens
get
clogged
with
leaves
(
in
fall)
and
that
divers
are
needed
to
clean
the
screens.
He
said
the
original
intake
consisted
of
traveling
screens
but
it
was
located
in
an
area
subject
to
sediment
deposition
and
was
plagued
by
sediment
in
and
around
the
intake.
He
said
that
the
original
intake
screen
portion
was
abandoned
and
only
the
intake
pump
well
&
pumps
were
retained.
The
screens
uses
an
air
backwash
system.
The
intake
is
covered
by
5
ft
of
water
and
includes
dolphins
for
protection.
Construction
occurred
before
the
plant
start
up
so
there
was
no
attempt
to
minimize
downtime
associated
with
intake
retrofit
construction.

He
said
to
call
Ron
Frey
(
difficult
to
find
in
office)
