FINISHED PRODUCTS OPERATDN
O NTHLY REI9RT
JULY- 197 WITH DE[EIONS
There were no changes during the month in the responsibilities assigned
to the Finished Products Operation.
A. Metal Finishing Operation
Fabrication schedules were met but button production fell short of
schedules by approximately 16%.
The production load continued at a level near the capacity of the
plant. Feed was received from only the Purex plant for the first
half of the month. Purex suspended operations for a week at mid-
month for scheduled flushing and cleaning operations. Feed started
coming from Redox on July 12, and continued steadily for a week when
a shutdown for repairs was necessary. Deliveries were resumed a
few days later. During the last ten days of the month feed was
received from both Purex and Redox and higher rates were necessary
in order to maintain this large production load. About twice as
much material was also received from the Product Recovery Operation
as was delivered from this source in June. The quality of the feed
was maintained at a very high level during the entire month with the
exception of seven Purex batches which were substandard due to
column flooding. It was necessary to recycle part of this material
in the Purex plant and part of it through Recuplex to make it
suitable for feed to the RMA Line.
The production of plutonium buttons fell short of schedule by 16%
this month. This negative variance was due to a combination of both
process and equipment difficulties. About 7% of the underage was
associated with buttons which failed to meet density specifications.
Two percent was related to the processing of smaller than normal
batches in wet chemistry and thereby limiting the capacity of the
plant. Seven percent of the underage was due to equipment troubles
which were so severe that schedules were affected. Firm plans have
been established for recovering this underage in future months.
Equipment problems were unusually severe during the month in the
wet chemical equipment. Delays were experienced due to plugged
lines and valve failures early in the month and the plant was
scheduled to work both the holiday as well as one Saturday in order
to maintain schedules. Operations progressed smoot a few days,
