Operation of the present accelerator is summarized and plans for a new injection system and additional machine modernization are described. Research results of both experimentalists and theorists are reviewed in very brief summaries; references are provided. (RWR)

Irradiation tests of aluminum-lithium co-producer target elements are planned for charging in the N-reactor. Although the target elements are subjected to extensive non-destructive testing to assure that defective pieces are not charged, it is necessary to have some knowledge of the failure characteristics of the targets under reactor conditions. To study the possible behavior of in-reactor failures, a series of defected test elements were tested in the high temperature, pressurized TF-9 facility located at 100 KE. The test objectives were: to follow the progress of the failures of target elements with several types of intentional defects, and to run the tests until, on several of the elements, the failure and corrosion had progressed essentially to a point of total destruction of the core. This report describes the intentionally defected elements used in the test and the progressive results of subjecting these defected elements to high temperature water.

The flexibility of N-Reactor will be demonstrated by comparing (in tabular form) the basic 4000 Mw Pu-only, weapons grade case with a 4800 Mw co-product, weapons grade mode including production of Po-210 and PU-238. The competitive position of N-Reactor in the AEC complex will be illustrated in a table summarizing 1964 production studies.

Friction tests were performed to determine the force required to slip a control plate between the control drum beryllium cylinder and the aluminum drum housing. Tests were conducted of ambient temperature and at 140°R with the control drum in the "as assembled" condition and reqorked to simulate nominal tolerance conditions.

This test was conducted to determine the structural adequacy of the core bond assembly; the stresses and deflections in the core band due to simulated startup and cold flow conditions; the ability of the core band to function after repeated thermal cycling; and to investigate the mechanics of assembly of the core band.

A friction test was performed to determine the torque required to rotate a control drum under various conditions of control drum and outer reflector sector interference.

None

A series of tests were run which simulated the thermal shock on a control drum during gaseous flow reactor startup and measured the distortion (thermal bow) resulting from this shock.
