the 18 month hiatus. I took a job with Tacoma Power as their
Generation Manager of Mechanical Engineers. I am in charge of
the repair and upgrade of units ranging in size from 500
kilowatts to 200 megawatts. It is hard to describe all the cool
projects I am working on. The following are some random updates:

top of the U21, a 29 MW, Allis Chalmers Hydro Generator. He came
for Thanksgiving and we went on a tour.

runners in 1998.

turbine/generator set the City installed at a CORPS Dam in 1994.
and I attended the Hydro Vision International Conference in
Nashville this past July. Celesty represented the Alden Research
Laboratory and presented a paper on Luddington Pumped Storage
intake design. During the conference she was surprised with an
award that she was recognized as one of the outstanding woman in
hydro!!! I was very proud of her!!
Here is an
incredible photo of the new Andritz runner installed at
Mossyrock. This runner swallows 6000 cfs at 303 feet of head. It
is so beautiful. It has been operating since 2008 and there are
no signs of cavitation:
We discovered cavitation on our LaGrande
runners. I wrote a welding procedure for the repair work. The
following photos depict some of the repair work:
Removing a LaGrande runner. Notice the
overhung lifting jig used to lift the runner horizontally out of
the gate case at its center of gravity. Note because of the
head, the inlet blade section is larger in diameter than the
This is pitting caused by cavitation. Notice
the metal has been eroded from the center of the blade leaving
the blade hollow.
All position welding jig used to easily
rotate the runner to the optimum position for repairing the
pitting damage. The repair is made by grinding out the pitted
metal hole and filling it back in with SS welding rod.
