include safety standards that would not
normally have been included in a paper
package to provide specific procedural
guidance instead of knowledge-based
decisions. This technology also provides
- human performance / technical human
performance advantages which augment
nuclear safety based on the ability to
perform any functionAdobe Pro provides.
Examples include color highlighting,
warning bubbles, enforcement of step-
by-step procedural compliance via
software and many other smart procedure
functions that ensure compliance to
rules and standards. This technology
allows the users to automatically validate
each shift that all drawings, documents
and procedures within the entire work
package are the latest revision.
In addition, the eWP iPad camera
can be utilized to photograph or video
an unexpected condition which the
worker may feel needs to be quickly
communicated to his supervision and
Site Safety personnel. With wireless
connectivity, these photos or videos
would be almost instantly available for
viewing by anyone at a workstation.
eWP has the potential to annually
save person-rem based on resource
savings and its ability to facilitate work
execution in a streamlined manor. This
online and outage savings is realized
year after year during the execution of
work. Dose will be saved because work
package problems can be addressed
quickly and efficiently, often without
requiring the workers to travel out of the
plant to get a work package revised and
support staff can resolve many package
change requests without traveling into
the plant. There also is the elimination
of delays from potentially contaminated
paperwork.
A recent example is at Clinton
Power Station, when returning from
Maintenance Outage C1M21, there
was a parts issue with Turbine Driven
Reactor Feed Pump “A”. This issue was
holding up power ascension and needed
immediate attention. Pictures were taken
via iPads and transmitted from the field
saving Planner in-field time and dose
by validating correct part remotely. The
planner saved 45 min in a 2-10 mrem field
with an estimated 2.0 mrem. This one
scenario is repeated monthly by several
planners at several sites as one example
of dose savings.
Cost Savings Response
To calculate cost savings, Exelon
reviewed actual historical data for
outage and online maintenance activities
completed normalized over a 2 year
period. The savings has been derived
based on the difference of time spent
between pre and post eWP deployment
for each functional area involved in
the work execution flow process for
Preventive and Corrective maintenance.
Time savings were calculated based on
the average number of work packages
in each area and converted to cost based
on labor rates. These cost savings apply
to the six Exelon Mid-West plants that
are the first to implement eWP and will
increase as we implement for the rest of
our fleet. Another aspect of cost savings
is eWP eliminates paper which also
supports Exelon’s green/carbon footprint
policies.
Innovation Response
Development
and
deployment
of eWP at Exelon Sites is a first in
this industry. Exelon first evaluated
the viability of this technology in
collaboration with EPRI and other
industry representatives via an EPRI
TAG Group. Exelon has implemented
a complete solution that passes data
between the Data Glance software and
Passport without the need to populate
both systems which reduces burden on
the planners. Other innovations include
the use of single bar code scanning to
populate multiple databases for better
Measurement and Test Equipment
(M&TE) traceability and zoom functions
that provide the ability to improve clarity
on documents/prints to ensure details are
legible. This technology utilizes Apple
iPads in the field that work seamlessly
whether connected to WiFi or not.
EPRI has followed our development
and deployment process and published
a report based on EPRI and Exelon
Operating Experience.
Productivity/Efficiency
Response
This eWP Project was initiated
to work more efficiently, reduce costs
and regain valuable resources while
maintaining high worker and nuclear
safety standards. This project reduces the
eWP technology in use.
