All parts of the prototype Purex oiling system h Bird has
developed are in their shop being fabricated. Test operation
in their plant is tentatively scheduled for mid September.
c. Consultant Agreement CA-147
Twenty-five copies of the final report for consulting agreement
CA-147, "Waste Storage Tank Design," submitted by Ammann and
Whitney, consulting engineers, accompanied with a Commentary
Report prepared by H. W. Stivers, has been distributed to interested
HAPO personnel. A meeting is scheduled with CEO, August 22, 1957,
to discuss this material and firm-up concepts for future tank de-
B. Process Technology
1. Critical-Mass Laboratory
The final drafts of the engineering report and conceptual design
drawings have been completed covering the proposed critical mass
laboratory. Complete resolution of all radiological safety aspects
has not been obtained. Differences in shielding aspects of the
design are being resolved and any resulting changes will be in-
corporated into the design. At that time the final report will be
issued. Resolution of all shielding aspects is expected by August
2. Plastics Development
Further refinements have been made in the development of a trans-
parent respiratory hood. The hood, as currently designed and
successfully demonstrated, is made of 20 gauge transparent vinyl
plastic and fits snugly around the neck. Complete visibility, and
sufficient air for deep breathing without fogging or lung strain
provide important advantages over present respiratory equipment.
Following further evaluation it is planned to use the hood within
Doors on either side of an air lock leading to the large fan room
in the basement of 271-T Building have been modified to permit use
of the fan room as a testing and training center for use of plastic
suits. Using this new demonstration facility, it is planned to
train personnel by collapsing the suits, adjusting air flows, and
otherwise manipulating the working variables. It will thus be
possible to avoid any undue concern by personnel entering suits in
contaminated work areas without prior experience.
