B. Process Technology
1. E Metal Processing
An important resolution in the chemical processing of E metal was
made by the Hanford Laboratories with the definition of limiting
nuclear-safe dimensions for slab and annular dissolver design
concepts. The maximum allowable slab thickness was defined as
twelve (12) inches; the maximum annular thickness in a seven (7)
foot diameter dissolver as eleven (11) inches. The annular concept
now offers a promising dissolver design for ob' lining the Redox
Phase III rate criterion with either E metal, I and E elements, or
conventional solid slugs. Preliminary design work is in progress
to define further engineering development and/or design verification
testing that may be needed prior to construction of the dissolvers.
A target beneficial use date, prior to January 1, 1959, precludes
extensive developmental activities and necessitates early completion
of this phase of work. Consequently, every engineering effort and
approach will be made to minimize any additional development work
required. Plans have been made with the Hanford Laboratories to
expedite any tests that may be required and to effect close liaison
between the developmental and design functions.
2. Buried Pipes
Sixteen 2" Schedule 40 stainless steel pipes leading from the pipe
galleries to the cells have been examined by the eddy current test
method in an effort to detect the degree of corrosion that may
exist in the piping. Five of these lines show evidence of
corrosion, with two lines being damaged over the entire length. In
one case the degree of attack is greater than 50 percent of the wall
thickness. Two other pipes were partially corroded with about one-
third and one-half their lengths attacked, respectively. In the
fifth pipe, start of corrosion was detected.
C. Plant Engineering
Two tools have been fabricated which will permit the remote removal
and replacement of the Bakelite plate and contacts in the canyon
electrical wall connectors. These are presently being tested for
Here’s what’s next.
