during an event. Designed to withstand 360mph
winds, the building has 18-inch thick
concrete walls. The rolling tornado-missileshield
door (Figure 2)-also 18 inches
thick-is 14 feet wide and 16 feet tall.
And if that weren't enough, two
new nuclear regional response centers
opened this year to ensure backup
equipment is available even following
unthinkable disasters that disable
multiple nuclear plants at the same
time. The $40 million centers-located
in the Phoenix, Ariz., and Memphis,
Tenn., metropolitan areas-are stocked
with portable generators, water pumps,
lighting, and other equipment that can
be rapidly deployed in the event of an
emergency. The equipment, which is
preloaded onto trailers, can be delivered
to any nuclear power plant in the
U.S. within 24 hours of a request.
Useful Redundancy
With all of the redundant backup systems,
TVA believes its new spent fuel pool instrumentation
system can keep running
off of the available power indefinitely.

Digital Writing Solution
Allows Timely Updates
to Drawings and Field
Reports
Skilled maintenance and service teams inspect
critical infrastructure, perform preventive
maintenance, and quickly respond
to issues to keep service levels high. It is
critical that such teams work with as-built
drawings that reflect original plans along
with the cumulative changes. Armed with
the current drawings, service teams can
avoid surprises.

The challenge is that drawings are
occasionally out of date. Changes are
often noted on paper drawings in real
time, but those changes are rarely entered
immediately in the master as-built
drawings. Marked up paper plans can be
misplaced, and even when the markups
do make it back to the office, sometimes
they are just added to a stack awaiting
entry by a computer-aided drafting
(CAD) operator.
However, a new solution is available to
document changes in the field and update
drawings that is as easy to use as a
pen and paper. Anoto, a digital writing
technology company, and ChasmTech, a
company focusing on field data collection
solutions, worked together to create
a product called SmartInk Redline.
The tool is a digital pen, drawing markup
solution (Figure 1) designed for utilities,
architects, and engineers who need timely
access to as-built information.
