Success at TVA Watts Bar Nuclear Plant (WBN)!
Over 10,000 pages of electrical calculations are superceded by an ETAP study
report
of only 81 pages held by Tamatha Reed.
"When
Julio Gomez came to WBN to supervise the Electrical Design Section
in 1995, he realized one of his challenges had
to be the consolidation and upgrade of the Electrical Power System
calculations. The perseverance and hard work of Site Engineering’s
Dennis Lashley and Ron Cox, and Corporate Engineering’s
Jerry Nicely, Tamatha Reed and Govind Patel has recently paid
off when, on Friday, 1/12/2001 the Electrical Engineering team
issued the WBN auxiliary power system calculations utilizing
the Electrical Transient Analysis Program (ETAP). As noted
in the attached photograph, this one ETAP-based calculation being
held by Tamatha Reed replaces all of the calculations shown on
the table. In addition to the large paper reduction, the ETAP
analysis technique provided better analysis capabilities for
developing the WBN degraded voltage requirements, which in turn
will provide Transmission Power Supply relaxed grid interface
requirements to WBN. This relaxation will postpone current projections
for TPS to install capacitor banks for Watts Bar Nuclear Plant
(a savings of 3.4 million dollars) and/or construct a new 161
kV transmission line between Rockwood and Harriman (a savings
of 9.4 million dollars). All individuals collaborating
on this project should be commended including those from WBN
Site Engineering, Corporate Engineering and Transmission Power
Supply."

“Prior
to using ETAP, TVA WBN was forced to maintain several databases
for their system. This cumbersome task was further complicated
with the need to control and validate the data for the purpose
of performing calculations. The program that was previously
used to perform power system studies lacked the intelligence
and capabilities to provide secure and acceptable results. Using
ETAP’s innovative 3-D database technology, TVA WBN has
combined all of their independent system data into one integrated,
controlled, and detailed database for the purpose of conducting
various types of power system analysis. The savings in
documentation and upgrade costs would not be possible without
the hard work and dedication of TVA engineers and the reliable
calculation results from ETAP.”
