A meeting was held in Wilmington on May 15, 1956, with representatives of Allegheny Ludlum to discuss possible production by Allegheny of uranium tubes in the number needed this next year for development work on tubular elements by Savannah River. Allegheny Ludlum, through king, had expressed a possible interest in the manufacture of uranium tubes. The Allegheny representatives, in the meeting, reiterated their interest in trying to determine whether Allegheny should consider entering the business of fabricating nuclear fuel elements and nuclear fuel element components, pointing out that the did not wish to do this work in existing facilities. Woodhouse covered the work done by Nuclear Metals, Inc., on bare uranium tubes. He stated that this work had reached a stage in which there would be needed, for development purposes, a supply of the order of 500 bare tubes at Savannah River over the next twelve months. These will be in excess of Nuclear Metals ability to supply. King as a director of NMI and Pierce as a former director were familiar with the NMI situation. On question by King, Worthington stated the order-of-magnitude of the tube requirements if the development work is successful and tubes are used on a …

The conceptual design of a nuclear ram jet-rocket missile is preserved. This missile is a modified, scaled-up AC-210 nuclear ram jet carrying ammonia in the space enclosed by the spike and inlet diffuser. The payload may be a 10,000 pound thermonuclear weapon or equivalent weight of reconnaissance equipment plus local shielding as in the AC-210 missile. The payload for a missile of body size equivalent to the AC-210 will be reduced by the weight of ammonia.

Modifications are described in the nuclear instrumentation system of the Shippingport Pressurized Water Reactor designed to monitor neutron flux level from source to 150% of reactor designed full power output, to compute the rate of change of the neutron flux level for indication and control, and to provide level and rate of change of level signals for reactor shutdown to prevent reactor damage.
