dependent upon the number of response
teams desired. If there are four teams,
there would be 16 events per year. There
is a need to limit the operation of the Phase
Two equipment to twice a year, so how
would the other 14 training sessions be
accomplished? VE permits training each
team with normal, abnormal and even
casualty operations without the actual
operation of the Phase Two equipment,
while maintaining training records and
actual scenario replay.

What cyber security services and
products are provided by General
Dynamics to the nuclear power industry?
With
significant
experience
supporting the Department of Defense
cyber security requirements, General
Dynamics has the capability to offer cyber
security solutions to the nuclear power
industry ranging from individual training
to operational and exercise environments
to meet the increasing requirements for
level 3 and 4 cyber security requirements
at any nuclear generating site.

How General Dynamics applications
help control the radiation dose to the
plant staff?
The visualization tool used by
General Dynamics, the Havok at game
engine, permits the inclusion of radiation
dose calculations (for any desired isotope
and source type) and allows modeling of
any location in the containment building
or any storage, transport or sampling
location. Using a monitor, mobile device
or game (3D head-mounted device), an
operator is able to visualize the real-time
dose he or she is accumulating. This
visualization permits the proper addition
of temporary shielding and incorporates
the impacts of other factors, such as
distance or time to assess radiation
dose. Operators may utilize robots to
survey the environment prior to entering
a containment building to validate the
levels of radioactivity. This survey of
the containment allows the operator
to capture the current condition of the
building and after altering the VE, make
decisions that could maintain or lower the
potential accumulated radiation dose.
The net effect is the immediately
available VE for planning, which
can either validate the maintenance
procedures in place or permit a real-
time change to the procedures that
take into account the newly discovered
conditions. These changes would allow
planning movement in such a way as
to either maintain the current exposure
predictions or minimize any additional
dose. Additionally, the VE can replicate
the various types of radiation detection
devices and the specific radiation types to
assess hazards, such as wet or dry spills or
airborne contaminants, to lower exposure
in an emergency situation.

hardware repair or replacement.
Westinghouse and Toshiba have jointly
developed an underwater laser welding
application for use in reactor vessel
nozzle welds. Westinghouse can use the
process to deposit a corrosion-resistant
layer or inlay for mitigating SCC, and to
seal existing cracks up to approximately
0.020 in (0.5 mm).
Westinghouse is committed to
supporting plant operation now and to
80 years and beyond. Our commitment
has led us to develop a technology plan
to help identify the most beneficial
technologies for supporting the nuclear
fleet in continuing safe and economical
long-term plant operation. The challenge
with operation to 80 years is to identify
potential new issues that could arise
that have not occurred thus far and to
develop new technologies to anticipate
and address these new issues before they
occur. Our long history as an original
equipment manufacturer, experience
we are gaining as we support the fleet
as they operate through 60 years, and
continued investment in the development
of new technologies, all demonstrate our
commitment to support plant operation
through 80 years and beyond. We
are actively soliciting customer input
on where we at Westinghouse should
commit our innovation investments to
support plant operation to 60 years, and
eventually to 80 years and beyond for
safe, reliable and profitable operation.
